    PURPOSE AND METHODS: As a part of reviewing the Multinational Association of Supportive Care in Cancer (MASCC) antiemetic guidelines in Perugia in 2009, an expert group identified directions for future antiemetic research. RESULTS AND CONCLUSIONS: In future trials, the prediction of nausea...... and vomiting may combine algorithms based on observed prognostic factors relating to the patient and the anticancer therapy, the identification of the genes that code for receptors, and pharmacogenetic studies of the metabolism of drugs. Design issues for future trials include standardising the emetic stimulus...... of an antiemetic. With current high rates of control of acute vomiting, future trials will need to consider new primary endpoints such as nausea, a complex symptom, where improvement is needed. Economic endpoints should be incorporated to ascertain the cost benefit of antiemetic prophylaxis, taking into account...

    A number of new advances have occurred over the past 2 years in the management of chemotherapy-related nausea and vomiting (CINV). A new neurokinin-1 receptor antagonist (NK1RA), netupitant, has been combined with palonosetron in a single oral tablet for treating the effects of moderately emetogenic chemotherapy (MEC) and highly emetogenic chemotherapy (HEC). Rolapitant, another NK1RA, unlike aprepitant, has a long half-life and does not block CYP-3A4 and therefore has fewer drug interactions. Olanzapine reduces nausea more effectively than aprepitant in patients who are receiving HEC and is a better rescue antiemetic than is metoclopramide. Ginger lacks efficacy as an antiemetic agent for CINV. Although there was some evidence in a pilot study of gabapentin as an antiemetic, it was no better in reducing CINV than was placebo. Compliance to guidelines in multiple settings ranges from 50%-60% but is improved by computerized order entry of antiemetics and recommendations displayed with chemotherapy. ©2016 Frontline Medical Communications.

    Ondansetron (GR 38032F) is a highly selective 5-HT3 receptor antagonist, one of a new class of compounds which may have several therapeutic applications. Animal and clinical studies show that ondansetron reduces the 24-hour incidence and severity of nausea and vomiting induced by cytotoxic drugs, including cisplatin, and by single exposure, high dose radiation. Ondansetron is more effective than high dose metoclopramide in the 24 hours following chemotherapy, and preliminary clinical evidence suggests that it is equally effective in the following 4 days. It is also more effective than the moderate doses of metoclopramide used to suppress emesis following radiotherapy. The antiemetic efficacy of ondansetron is enhanced by dexamethasone in cisplatin-treated patients. Importantly, extrapyramidal effects have not been reported with ondansetron. Further comparisons are required with standard combination antiemetic therapy to complement the data presently available. Thus, ondansetron is a promising new agent for prophylaxis against nausea and vomiting in chemotherapy and radiotherapy. It may be particularly useful in young and elderly patients who are more susceptible to extrapyramidal symptoms induced by high dose metoclopramide. With its improved tolerability and clinical response profiles, ondansetron represents an important advance in a difficult area of therapeutics. 101 refs.

    Nausea and vomiting are common in cancer patients. The most common cause of nausea and vomiting is the administration of cytotoxic chemotherapy. Apart from chemotherapy-induced nausea and vomiting (CINV), biological agents may also cause these symptoms. In this review, discussion will be focused on management of nausea and vomiting due to antineoplastic therapies. The cornerstone of effective management of nausea and vomiting secondary to these antineoplastic drugs is the prevention with the use of appropriate guideline-directed combination antiemetic regimen. Type 3 serotonin receptor antagonists (5HT3RAs), neurokinin-1 receptor antagonists (NK1RAs), and dexamethasone are the backbone antiemetic drugs. In recent years, newer drugs and preparations have been introduced for clinical use and include second-generation 5HT3RA, palonosetron; granisetron transdermal patch; the recently introduced NK1RA rolapitant; and the novel oral combined drug NEPA (netupitant plus palonosetron); and last but not least, the atypical antipsychotic olanzapine.

    To determine patient expectations of antiemetic treatment in the ED. Survey of adult ED patients with nausea. expectation of antiemetic treatment as symptoms being 'totally gone', 'a lot less', 'a little less' and 'the same'. comparison between expectations and symptom change when expectations were met; general views on indications for treatment, treatment satisfaction and reasons for additional medication use. Of 176 surveyed, treatment expectation was recorded by 165 (94%). These were: 'totally gone', 'a lot less' or 'a little less' for 60 (36%), 84 (51%) and 21 (13%), respectively. This pre-treatment nomination, was matched or exceeded by the reported level of symptom reduction at 30 min, for 43/87 (49%, 95% CI: 39-60) whose expectations were met, and 6/33 (18%, 95% CI: 7-35) whose were not. The majority (117/176, 66%) believed treatment should be reserved for moderate or severe nausea; 158/176 (90%) would accept treatment if offered; 130/165 (79%) expected a treatment effect by 30 min. Treatment satisfaction findings were similar to expectations being met. Further drug treatment at 30 min was desired by 29/120 (24%) who received an antiemetic drug. Most were improved, but believed additional drugs might help more. Of the 91 not wanting more treatment, most were improved and thought no more drugs were necessary. Most patients expected antiemetic treatment to make symptoms at least 'a lot less'. Most also believe treatment should be reserved for moderate or severe nausea, and should take effect by 30 min. © 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    Nausea and vomiting in pregnancy remains the most common cause of hospitalization in the first half of pregnancy. Although the exact cause is largely unknown, an interaction of genetic, biological and psychological factors is plausible. An endocrine trigger for hyperemesis has been linked with both ovarian and placental hormones, but this association requires further clarification. The use of type-3 serotonin receptor antagonists is increasing but as yet there are no convincing data to demonstrate their superiority over the other antiemetics. A computerized search was conducted using PubMed, Embase, Cinahl, Lilacs, ISI Web of Science, the Cochrane Central Register of Controlled Trials (all from inception or 1960 to October 2010), and Research Registries of ongoing trials. The key words used were nausea, vomiting, emesis, hyperemesis gravidarum, morning sickness, pregnancy, pregnancy complications, treatment, efficacy, effectiveness, antiemetics, safety and teratogenesis. The precise mechanism underlying hyperemesis gravidarum remains unclear, but appears to be multifactorial. As yet there is no evidence that any antiemetic class is superior to another with respect to effectiveness.

    To update a key recommendation of the American Society of Clinical Oncology antiemetic guideline. This update addresses the use of the oral combination of netupitant (a neurokinin 1 [NK1] receptor antagonist) and palonosetron (a 5-hydroxytryptamine-3 [5-HT3] receptor antagonist) for the prevention of acute and delayed nausea and vomiting in patients receiving chemotherapy. An update committee conducted a targeted systematic literature review and identified two phase III clinical trials and a randomized phase II dose-ranging study. In one phase III trial, the oral combination of netupitant and palonosetron was associated with higher complete response rates (no emesis and no rescue medications) compared with palonosetron alone in patients treated with anthracycline plus cyclophosphamide chemotherapy (74% v 67% overall; P = .001). In another phase III trial, the oral combination of netupitant and palonosetron was safe and effective across multiple cycles of moderately or highly emetogenic chemotherapies. In the phase II dose-ranging study, each dose of netupitant (coadministered with palonosetron 0.50 mg) produced higher complete response rates than palonosetron alone among patients receiving cisplatin-based chemotherapy. The highest dose of netupitant (ie, 300 mg) was most effective. All patients who receive highly emetogenic chemotherapy regimens (including anthracycline plus cyclophosphamide) should be offered a three-drug combination of an NK1 receptor antagonist, a 5-HT3 receptor antagonist, and dexamethasone. The oral combination of netupitant and palonosetron plus dexamethasone is an additional treatment option in this setting. The remaining recommendations from the 2011 ASCO guideline are unchanged pending a full update.

    Chemotherapy-induced nausea and vomiting (CINV) is associated with a significant deterioration in quality of life and is perceived by patients as a major adverse effect of the treatment. The purpose of the review is to determine the safety and efficacy of current antiemetic agents. Information on antiemetic guideline recommended antiemetics derived from PubMed showed that the first and second generation 5-hydroxytryptamine-3 (5-HT3) receptor antagonists have been safe and effective in the control of acute emesis with a small number of patients experiencing mild headache, diarrhea, or constipation. Improvement in the prevention of delayed emesis has occurred with the neurokinin (NK)-1 receptor antagonists aprepitant, netupitant, and rolapitant with mild headache, constipation, hiccups, and fatigue the most commonly reported adverse events. Olanzapine, an antipsychotic that blocks multiple neurotransmitters in the central nervous system, appears to be effective in the prevention of nausea and emesis with mild short term sedation the only reported adverse event. The current antiemetics that are recommended by the various international antiemetic guidelines are safe and effective in the prevention of chemotherapy-induced nausea and vomiting when used in the recommended doses. Practitioners should consult the antiemetic guidelines for patients receiving chemotherapy.

    CONCLUSION: Although this study is not prospective, it is homogenous for treatment modalities and patient selection. Complete response was observed in 63% of courses; however this antiemetic affect is not found to be satisfactory. In order to develope better protocols there is need for prospective studies on homogenous group. Antiemetic efficiency has to associate for chemotherapy protocols.

    The use of antiemetic drugs for patients receiving chemotherapy with low or minimal emetic risk has been recognized as a growing concern for health care costs and patients' welfare. Relatively few studies have examined antiemetic prophylaxis or treatment of emesis associated with chemotherapy with lower emetic risk. To describe the pattern in Japan of overprescribing prophylactic antiemetic drugs to patients who have received intravenous chemotherapy with minimal or low emetic risk. This secondary analysis of a health insurance claims database linked with the hospital-based cancer registry of 122 designated cancer care hospitals covered the period from September 1, 2010, to December 31, 2012. Data were included from patients who (1) were diagnosed with breast, lung, colorectal, stomach, cervical, or prostate cancer; (2) were 20 years or older at the time of the diagnosis; and (3) received intravenous chemotherapy with minimal or low emetic risk. The data from patients with advanced stage cancer (stage IV) were excluded. Data were analyzed from March 20, 2014, to June 30, 2016. The percentage of chemotherapy administration involving patients prescribed prophylactic antiemetic drugs, namely, a neurokinin 1 receptor antagonist, serotonin receptor antagonist, and/or dexamethasone, was calculated. The costs of potentially unnecessary antiemetic drugs were estimated using the National Health Insurance drug price list for 2011. A total of 8545 patients (5886 women [68.9%] and 2659 men [31.1%]; mean [SD] age, 61.9 [12.8] years) undergoing 73 577 administrations of chemotherapy with minimal emetic risk (2464 patients; 22 619 administrations) or low emetic risk (6081 patients; 50 958 administrations) were identified. Of these, patients who received 24 373 administrations of chemotherapy with a low emetic risk (47.8%) and 633 administrations of chemotherapy with a minimal emetic risk (2.8%) were prescribed serotonin receptor antagonists and dexamethasone.

    Approximately 30-59% of patients undergoing cranial or craniospinal radiotherapy experience nausea and/or vomiting. Here, we evaluated the effectiveness of granisetron for controlling emesis in patients treated with cranial or craniospinal radiotherapy. Between December 2011 and January 2013, 34 patients (19 males, 15 females; age range, 3-80 years) received cranial or craniospinal radiotherapy at our department. All but one male patient, who developed meningitis during the irradiation period were enrolled in this retrospective study. Patients who experienced irradiation-induced vomiting (grade 1) or nausea (grade 2) were treated with granisetron as a rescue anti-emetic. Episodes were graded as no vomiting, no nausea, no anti-emetic; no vomiting, nausea, no anti-emetic; no vomiting, nausea with anti-emetic; and vomiting. Of the 9 patients who underwent whole-brain or whole neural-axis irradiation, 5 (55.6%) experienced grade 2 nausea or vomiting. Two of 6 patients (33.3%) treated with whole ventricle irradiation experienced grade 2 nausea or vomiting. Three of 18 patients (16.7%) who underwent local-field irradiation experienced grade 2 nausea or vomiting. Patients who underwent wide-field irradiation experienced nausea, vomiting, and anorexia (p<0.05). Complete response (no vomiting, no additional rescue anti-emetic, and no nausea) was observed in 5 of 9 patients treated with granisetron. Four of 9 patients (44.4%) treated with granisetron experienced constipation (grade 1 or 2); its administration had no major adverse effects in our study population. Rescue therapy with granisetron is safe and effective to treat nausea and vomiting in patients subjected to cranial or craniospinal irradiation. (author)

    Acute gastroenteritis (AG) represents both the main cause of acute vomiting in children under 3 years old and a major cause of access to the emergency department. Even if several drugs may be able to reduce the emesis, the pharmacological treatment of vomiting in children remains a controversial issue, and several drugs are prescribed outside their authorized drug label with respect dosage, age, indication, or route of administration and are named as off-label. The aim of present study was to assess the off-label use of antiemetic drugs in patients less than 18 years with vomiting related to AG. This study was carried out in eight pediatric emergency departments in Italy. The following data were obtained crossing the pharmacy distribution records with emergency departments' patient data: sex and age of the patients and detailed information for each drug used (indication, dose, frequency, and route of administration). We recorded that antiemetic drugs were prescribed in every year, particularly in children up to 2 years old, and compared with both literature data and data sheet; 30 % of the administered antiemetics were used off-label. In particular, domperidone was the only antiemetic used labeled for AG treatment in pediatric patients, while metoclopramide and ondansetron have been off-label for both age and indications (i.e., AG treatment). In conclusion, we documented an off-label use of antiemetics in children, and this could represents a problem of safety for the patient and a legal risk for the prescribing physician if patients have an unwanted or bad outcome from treatment.

    Full Text Available Purpose: Adherence to international antiemetic prophylaxis guidelines like those of ASCO can result in better control of chemotherapy-induced nausea and vomiting; however, the extent of implementation of such guidelines in India is unknown. Therefore, this survey was planned. Methods: This study was an anonymized cross-sectional survey approved by the ethics committee. Survey items were generated from the clinical questions given in the ASCO guidelines. The survey was disseminated through personal contacts at an oncology conference and via e-mail to various community oncology centers across India. The B1, B2, and B3 domains included questions regarding the optimal antiemetic prophylaxis for high, moderate, and low-minimal emetogenic regimens. Results: Sixty-six (62.9% of 105 responded and 65 centers (98.5% were aware of the published guidelines. The partial, full, and no implementation scores were 92.5%, 4.5%, and 3.0%, respectively. Full implementation was better for the low-minimal emetogenic regimens (34.8% than the highly emetogenic regimens (6.1%. The three most frequent reasons for hampered implementation of ASCO guidelines in routine chemotherapy practice cited by centers were a lack of sensitization (26 centers; 39.4%, lack of national guidelines (12 centers; 18.2%, and lack of administrative support (10 centers; 15.2%. Conclusion: Awareness regarding ASCO antiemetic guidelines is satisfactory in Indian oncology practices; however, there is a need for sensitization of oncologists toward complete implementation of these guidelines in their clinical practice.

    Full Text Available Objective. Olanzapine is proved to be effective for chemotherapy induced nausea and vomiting (CINV. But its efficacy in combination with standard antiemetic therapy is unknown. The purpose of this study is to prove the preventive effect of olanzapine for the prevention of CINV caused by highly emetogenic chemotherapy when used with standard antiemetic therapy. Method. Gynecologic cancer patients receiving cisplatin-based chemotherapy who had grade 2 or 3 nausea in overall phase (0–120 h after chemotherapy despite standard therapy were assigned to this study. From the next cycles to cycles in which patients developed grade 2 or 3 nausea, they received olanzapine with standard therapy. 5 mg oral olanzapine was administered for 7 days from the day before chemotherapy. The effectiveness of preventive administration of olanzapine was evaluated retrospectively. The primary endpoint was nausea control rate (grade 0 or 1 with olanzapine. Results. Fifty patients were evaluable. The nausea control rate with olanzapine was improved from 58% to 98% in acute phase (0–24 h after chemotherapy and 2% to 94% in delayed phase (24–120 h after chemotherapy. In overall phase, the nausea control rate improved from 0% to 92%, and it was statistically significant (P<0.001. Conclusion. Preventive use of olanzapine combined with standard antiemetic therapy showed improvement in control of refractory nausea.

    Cisplatin-like chemotherapeutics cause vomiting via release of multiple neurotransmitters (dopamine, serotonin (5-HT), or substance P (SP)) from the gastrointestinal enterochromaffin cells and/or the brainstem via a calcium dependent process. Diverse channels in the plasma membrane allow extracellular Ca(2+) entry into cells for the transmitter release process. Agonists of 5-HT3 receptors increase calcium influx through both 5-HT3 receptors and L-type Ca(2+) channels. We envisaged that L-type calcium agonists such as FPL 64176 should cause vomiting and corresponding antagonists such as nifedipine would behave as broad-spectrum antiemetics. Administration of FPL 64176 did cause vomiting in the least shrew in a dose-dependent fashion. Nifedipine and the 5-HT3 receptor antagonist palonosetron, potently suppressed FPL 64176-induced vomiting, while a combination of ineffective doses of these antagonists was more efficacious. Subsequently, we investigated the broad-spectrum antiemetic potential of nifedipine against diverse emetogens including agonists of serotonergic 5-HT3- (e.g. 5-HT or 2-Me-5-HT), SP tachykinin NK1- (GR73632), dopamine D2- (apomorphine or quinpirole), and cholinergic M1- (McN-A-343) receptors, as well as the non-specific emetogen, cisplatin. Nifedipine by itself suppressed vomiting in a potent and dose-dependent manner caused by the above emetogens except cisplatin. Moreover, low doses of nifedipine potentiated the antiemetic efficacy of non-effective or semi-effective doses of palonosetron against vomiting caused by either 2-Me-5-HT or cisplatin. Thus, our findings demonstrate that activation of L-type calcium channels causes vomiting, whereas blockade of these ion channels by nifedipine-like antagonists not only provides broad-spectrum antiemetic activity but can also potentiate the antiemetic efficacy of well-established antiemetics such as palonosetron. L-type calcium channel antagonists should also provide antiemetic activity against drug

  4. Mechanisms of Broad-Spectrum Antiemetic Efficacy of Cannabinoids against Chemotherapy-Induced Acute and Delayed Vomiting

    Nissar A. Darmani

    2010-09-01

    Full Text Available Chemotherapy-induced nausea and vomiting (CINV is a complex pathophysiological condition and consists of two phases. The conventional CINV neurotransmitter hypothesis suggests that the immediate phase is mainly due to release of serotonin (5-HT from the enterochromaffin cells in the gastrointestinal tract (GIT, while the delayed phase is a consequence of release of substance P (SP in the brainstem. However, more recent findings argue against this simplistic neurotransmitter and anatomical view of CINV. Revision of the hypothesis advocates a more complex, differential and overlapping involvement of several emetic neurotransmitters/modulators (e.g. dopamine, serotonin, substance P, prostaglandins and related arachidonic acid derived metabolites in both phases of emesis occurring concomitantly in the brainstem and in the GIT enteric nervous system (ENS [1]. No single antiemetic is currently available to completely prevent both phases of CINV. The standard antiemetic regimens include a 5-HT3 antagonist plus dexamethasone for the prevention of acute emetic phase, combined with an NK1 receptor antagonist (e.g. aprepitant for the delayed phase. Although NK1 antagonists behave in animals as broad-spectrum antiemetics against different emetogens including cisplatin-induced acute and delayed vomiting, by themselves they are not very effective against CINV in cancer patients. Cannabinoids such as D9-THC also behave as broad-spectrum antiemetics against diverse emetic stimuli as well as being effective against both phases of CINV in animals and patients. Potential side effects may limit the clinical utility of direct-acting cannabinoid agonists which could be avoided by the use of corresponding indirect-acting agonists. Cannabinoids (both phyto-derived and synthetic behave as agonist antiemetics via the activation of cannabinoid CB1 receptors in both the brainstem and the ENS emetic loci. An endocannabinoid antiemetic tone may exist since inverse CB1

    Background and purpose: To report recommendations given in the Multinational Association of Supportive Care in Cancer (MASCC) International Consensus Conference regarding the use of antiemetics in radiotherapy. Patients and methods: A steering committee under MASCC auspice chose panel participants for the guidelines development process on prevention of chemotherapy- and radiotherapy-induced emesis (RIE). Pertinent information from published literature as of March 2004 was reviewed for the guideline process. Both the MASCC level of scientific confidence and level of consensus, and the American Society of Clinical Oncology (ASCO) type of evidence and grade for recommendation were adopted. Results: Total body irradiation is classified at high risk, upper abdomen at moderate, lower thorax, pelvis, cranium (radiosurgery) and craniospinal at low, head and neck, extremities, cranium and breast at minimal risk. The recommendations for the use of antiemetics in radiotherapy are as follows: prophylaxis with a 5-HT3 antagonist in patients at high and moderate risk levels of RIE (±dexamethasone in the former group), prophylaxis or rescue with a 5-HT3 antagonist in the low risk group, and rescue with dopamine or a 5-HT3 receptor antagonist in minimal risk level. Conclusions: These recommendations represent a valid tool for prophylaxis and treatment of RIE in clinical practice

    The 5-HT 3 receptor antagonists are the most potent antiemetics known at present. Lerisetron is a new 5-HT 3 receptor antagonist chemically unrelated to other antagonists like Ondansetron. An emesis model in the dog induced by irradiation with 60 Co was used, and 8 Gy were administered over the total body surface. An irradiated control group was established and received no medication, and two irradiated groups received treatment with either Ondansetron or Lerisetron. The 'up-down' technique was employed to determine the effective dose (ED 50 ). A logarithmic scale was used to increase or decrease the doses in each case. The initial doses were 300 μg/kg for Ondansetron and 100 μg/kg for Lerisetron. All animals in the control group vomited. The ED 50 of Ondansetron was 178 ± 151 μg/kg body wt and that of Lerisetron was 63 ± 18 μg/kg. Lerisetron is more potent and presented less individual variability than Ondansetron, but its antiemetic effects were equally effective. (orig.)

Several antiemetic options exist to manage CINV. Corticosteroids, serotonin receptor antagonists, and neurokinin receptor antagonists are the classes most commonly used in the prevention of CINV. There are many alternative drug classes utilized for the prevention and management of CINV such as antihistamines, benzodiazepines, anticonvulsants, cannabinoids, and dopamine receptor antagonists. Medications belonging to these classes generally have lower efficacy and are associated with more adverse effects. They are also not as well studied compared to the aforementioned agents. This review will focus on dronabinol, a member of the cannabinoid class, and its role in CINV. Cannabis sativa L. (also known as marijuana contains naturally occurring delta-9-tetrahydrocannibinol (delta-9-THC. The synthetic version of delta-9-THC is the active ingredient in dronabinol that makes dronabinol an orally active cannabinoid. Evidence for clinical efficacy of dronabinol will be analyzed in this review as monotherapy, in combination with ondansetron, and in combination with prochlorperazine.

    The purposes of this study were to evaluate the effect of implementation of institutional guidelines for low emetic risk chemotherapy with docetaxel and estimate the cost saving for all low emetic risk chemotherapies. We examined the clinical effect of preparing and implementing institutional antiemetic guidelines for the breast cancer patients receiving adjuvant docetaxel therapy. Although the antiemetic medication for such patients used to be ondansetron 4 mg plus dexamethasone 8 mg (OND + DEX), it was changed to dexamethasone (DEX) 12 mg alone after implementation of the institutional guidelines. The effectiveness and adverse effects of DEX alone (56 patients, 205 courses) were compared with those of OND + DEX (41 patients, 151 courses). The cost saving was calculated from the antiemetic costs in both groups. The annual cost saving was estimated from the number of all low emetic risk chemotherapies in a year. The incidences of nausea (19.5% versus 16.1%), vomiting (2.4% versus 0%), constipation (34.1% versus 30.4%), and insomnia (17.1% versus 17.9%) were not significantly different between the OND + DEX group and DEX alone group. In all low emetic risk chemotherapies, US $78,883 of potential cost saving was estimated in the first year after changing the antiemetic treatment. The present results suggest that DEX alone is equally effective for preventing nausea and vomiting and less expensive compared with a 5-HT(3) receptor antagonist plus DEX in low emetic risk chemotherapy with docetaxel.

    Chemotherapy Induced Nausea and Vomiting (CINV) is a serious health concern in the treatment of cancer patients. Conventional routes for administering anti-emetics (i.e. oral and parenteral) have several drawbacks such as painful injections, poor patient compliance, dependence on skilled personnel, non-affordability to majority of population (parenteral), lack of programmability and suboptimal bioavailability (oral). Hence, we have developed a trans-epidermal antiemetic drug delivery patch using out-of-plane hollow silicon microneedle array. Microneedles are pointed micron-scale structures that pierce the epidermal layer of skin to reach dermal blood vessels and can directly release the drug in their vicinity. They are painless by virtue of avoiding significant contact with dermal sensory nerve endings. This alternate approach gives same pharmacodynamic effects as par- enteral route at a sparse drug-dose requirement, hence negligible side-effects and improved patient compliance. Microneedle design attributes were derived by systematic study of human skin anatomy, natural micron-size structures like wasp-sting and cactus-spine and multi-physics simulations. We used deep reactive ion etching with Bosch process and optimized recipe of gases to fabricate high-aspect-ratio hollow silicon microneedle array. Finally, microneedle array and polydimethylsiloxane drug reservoir were assembled to make finished anti-emetic patch. We assessed microneedles mechanical stability, physico-chemical properties and performed in-vitro, ex- vivo and in-vivo studies. These studies established functional efficacy of the device in trans-epidermal delivery of anti-emetics, its programmability, ease of use and biosafety. Thus, out-of-plane hollow silicon microneedle array trans-epidermal antiemetic patch is a promising strategy for painless and effective management of CINV at low cost in mainstream healthcare.

    Full Text Available Combination antiemetic regimens targeting multiple molecular pathways associated with emesis have become the standard of care for prevention of chemotherapy-induced nausea and vomiting (CINV related to highly and moderately emetogenic chemotherapies. Antiemetic consensus guidelines from several professional societies are widely available and updated regularly as new data emerges. Unfortunately, despite substantial research supporting the notion that guideline conformity improves CINV control, adherence to antiemetic guidelines is unsatisfactory. While studies are needed to identify specific barriers to guideline use and explore measures to enhance adherence, a novel approach has been taken to improve clinician adherence and patient compliance, with the development of a new combination antiemetic. NEPA is an oral fixed combination of a new highly selective NK1 receptor antagonist (RA, netupitant, and the pharmacologically and clinically distinct 5-HT3 RA, palonosetron. This convenient antiemetic combination offers guideline-consistent prophylaxis by targeting two critical pathways associated with CINV in a single oral dose administered only once per cycle. This paper will review and discuss the NEPA data in the context of how this first combination antiemetic may overcome some of the barriers interfering with adherence to antiemetic guidelines, enhance patient compliance, and offer a possible advance in the prevention of CINV for patients.

    Injection pain has been associated with veterinary use of the antiemetic maropitant (Cerenia, Pfizer Animal Health). Cerenia is formulated using sulphobutylether-beta-cyclodextrin to bind maropitant and mitigate injection pain. The objective of this study was to determine whether the temperature of Cerenia alters binding between maropitant and sulphobutylether-beta-cyclodextrin and affects injection pain. Binding decreased as temperature increased, and Cerenia-elicited injection pain increased at warmer drug temperatures. These data suggest that the amount of free unbound maropitant increases with temperature and that injection pain increases with temperature in a similar fashion. Clinically, these studies suggest that injection of refrigerated Cerenia may significantly reduce or eliminate pain associated with SC injection of Cerenia.

    Full Text Available Introduction: Nausea and vomiting are the most common complications after minor head trauma that increases the risk of intracranial pressure rising. Therefore, the present study was aimed to compare the antiemetic effects of metoclopramide and ondansetron in the treatment of post-traumatic nausea and vomiting. Methods: The study was a controlled, randomized, double blind clinical trial, which was conducted in the first 6 months of 2014 in emergency department Al-Zahra and Kashani Hospitals in Isfahan, Iran. The patients with minor head trauma associated with nausea and vomiting were randomly divided into 2 groups: treatment with metoclopramide (10mg/2ml, slow injection and treatment with ondansetron (4mg/2ml, slow injection. The comparison between the 2 groups was done regarding antiemetic efficacy and side effects using SPSS 21 statistical software. Results: 120 patients with minor head trauma were distributed and studied into two groups of 60 patients (mean age 35.6±14.1 years; 50.0% male. Administration of both ondansetron and metoclopramide significantly reduced the severity of nausea (P<0.001. Changes in the severity of nausea in both groups before and after the treatment revealed that nausea had been decreased significantly in both groups (P < 0.001. The incidence of fatigue (p=0.44, headache (p=0.58 and dystonia (p=0.06 had no significant difference in the two groups but the incidence of drowsiness and anxiety in the metoclopramide group was significantly higher (P < 0.001. Conclusion: The present study indicated that the treatment effectiveness of ondansetron and metoclopramide are similar. However, incidence of drowsiness and anxiety in the metoclopramide was considerably higher. Since these complications can have adverse effects on the treatment of patients with brain injury, it is suggested that it may be better to use ondansetron in these patients.

    This review provides background information on chemotherapy-induced nausea and vomiting (CINV) classification and pathophysiology and reviews various antiemetic agents for CINV prophylaxis, including corticosteroids, serotonin receptor antagonists (5-HT3 RAs), tachykinin NK1 receptor antagonists (NK1 RAs), and olanzapine. Other less commonly used agents are briefly discussed. Practical considerations are reviewed as well, including emetogenicity of chemotherapeutic regimens, patient-specific risk factors for CINV, principles of CINV management, health economics outcome research, and quality of life. Available data on the newly FDA-approved antiemetic combination netupitant/palonosetron (NEPA) is also reviewed. Prevention of CINV is an important goal in managing patients with cancer and is especially difficult with respect to nausea and delayed CINV. Corticosteroids are a mainstay of CINV prophylaxis and are usually given in combination with other therapies. The 5-HT3 RA palonosetron has shown increased efficacy over other agents in the same class for prevention of delayed emesis with moderately emetogenic chemotherapy and NK1 RAs improve emesis prevention in combination with 5-HT3 RAs and dexamethasone. Olanzapine has shown efficacy for CINV prophylaxis and the treatment of breakthrough CINV. The new combination therapy, NEPA, has been shown to be efficacious for the prevention of acute, delayed, and overall CINV. Risk factors that have been identified for CINV include gender, age, and alcohol intake. It is important to assess the emetogenicity of chemotherapy regimens as well as the potential impact of patient risk factors in order to provide adequate prophylaxis. Acute and delayed CINV are severe, burdensome side effects of chemotherapy; however, new data on prevention and the discovery of new agents can further improve CINV control.

    Background Migraine is a common, disabling condition and a burden for the individual, health services and society. Many sufferers choose not to, or are unable to, seek professional help and rely on over-the-counter (OTC) analgesics. Diclofenac is an established analgesic, and new formulations using the potassium or epolamine salts, which can be dissolved in water, have been developed for rapid absorption, which may be beneficial in acute migraine. Co-therapy with an antiemetic should help to reduce the nausea and vomiting commonly associated with migraine. Objectives To determine the efficacy and tolerability of diclofenac, alone or in combination with an antiemetic, compared to placebo and other active interventions in the treatment of acute migraine headaches in adults. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the Oxford Pain Relief Database, ClinicalTrials.gov, and reference lists for studies through 27 September 2011. Selection criteria We included randomised, double-blind, placebo- and/or active-controlled studies using self administered diclofenac to treat a migraine headache episode, with at least 10 participants per treatment arm. Data collection and analysis Two review authors independently assessed trial quality and extracted data. We used numbers of participants achieving each outcome to calculate relative risk (or ‘risk ratio’) and numbers needed to treat to benefit (NNT) or harm (NNH) compared to placebo or a different active treatment. Main results Five studies (1356 participants) compared oral diclofenac with placebo, and one also compared it with sumatriptan; none combined diclofenac with a self administered antiemetic. Four studies treated attacks with single doses of medication, and two allowed an optional second dose for inadequate response. Only two studies, with three active treatment arms, provided data for pooled analysis of primary outcomes. For single doses of diclofenac

    Nausea is a common problem in ED patients. Antiemetic drugs have been used in the ED for decades, but a recent Cochrane review found no convincing evidence for the benefit of antiemetic drugs over placebo. This was largely based on three placebo-controlled trials, which found mean Visual Analog Scale (VAS) changes for various drugs and placebo, to be similar. However, reliance on mean VAS change as the primary outcome measure has probably been a mistake. It does not give information on the number of improved patients, so these cannot be compared between groups. Alternative primary outcome measures warrant further exploration. Use of a VAS cut-off level indicative of clinically significant symptom improvement would allow comparison of numbers of patients with improved nausea ratings. This is proposed as the best option currently available. Preliminary testing of this outcome measure suggests that the conclusions of past studies may be misleading, and that the question of antiemetic efficacy for ED patients is not yet answered. © 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    Despite significant advances in supportive care in oncology, many patients with cancer still experience chemotherapy- induced nausea and vomiting (CINV). Historically, there were only 3 neurotransmitter receptors (dopamine D2, cannabinoid- 1, and 5-hydroxytryptamine-3) that were the known targets for antiemetic therapy. Major advances in the management of chemotherapy-induced emesis were seen with the introduction of 5-hydroxytryptamine-3 receptor antagonists, which include palonosetron, ondansetron, tropisetron, dolasetron, and granisetron. However, recently, selective inhibitors of substance P have shown promising activity in the management of CINV in patients with cancer. Substance P mediates a number of biologic effects by binding to a specific neuroreceptor, neurokinin-1 (NK-1). Among the NK-1 receptor antagonists, aprepitant has been approved for the treatment of CINV. Currently, several other NK-1 receptor antagonists, including casopitant, vestipitant, netupitant, and SCH619734, are undergoing clinical evaluation for the prevention of CINV in patients with a variety of malignancies. The clinical potential of these novel NK-1 receptor antagonists and their respective ongoing clinical trials for the management of chemotherapy-induced emesis are discussed briefly herein.

    Chemotherapy-induced nausea and vomiting (CINV) is one of the most common symptoms feared by patients, but may be prevented or lessened with appropriate medications. Several antiemetic options exist to manage CINV. Corticosteroids, serotonin receptor antagonists, and neurokinin receptor antagonists are the classes most commonly used in the prevention of CINV. There are many alternative drug classes utilized for the prevention and management of CINV such as antihistamines, benzodiazepines, anticonvulsants, cannabinoids, and dopamine receptor antagonists. Medications belonging to these classes generally have lower efficacy and are associated with more adverse effects. They are also not as well studied compared to the aforementioned agents. This review will focus on dronabinol, a member of the cannabinoid class, and its role in CINV. Cannabis sativa L. (also known as marijuana) contains naturally occurring delta-9-tetrahydrocannibinol (delta-9-THC). The synthetic version of delta-9-THC is the active ingredient in dronabinol that makes dronabinol an orally active cannabinoid. Evidence for clinical efficacy of dronabinol will be analyzed in this review as monotherapy, in combination with ondansetron, and in combination with prochlorperazine

    To evaluate and compare the efficacy of the combination of midazolam and dexamethasone, with midazolam and dexamethasone alone, for the prevention of postoperative nausea and vomiting (PONV) in female patients undergoing middle ear surgery. A prospective, randomized, double-blind, placebo-controlled study in 80 female patients (mean age 32.6 years), undergoing middle ear surgery with general anesthesia at Ohud Hospital, Madina, Kingdom of Saudi Arabia from May 2007 to May 2008. Patients were classified into 4 groups. They received intravenous normal saline (S group), midazolam 0.075 mg/kg (M group), or dexamethasone 10 mg (D group), or a combination of midazolam and dexamethasone (MD group), before the induction of anesthesia. Postoperatively for 24 hours observation and assessment of nausea, vomiting, rescue anti-emetics, and side effects of the study drugs such as headache and drowsiness were carried out. There was a significant difference between the 4 groups. The MD group was the least to develop PONV compared to other groups (p<0.01). Regarding nausea, there was a non-significant difference between the 4 groups, although the MD group developed the least symptoms among the 4 groups, there were no significant differences in pain intensity and side effects such as, headache, dizziness, and drowsiness between the 4 groups. The combination of midazolam 0.075 mg/kg and dexamethasone 10 mg intravenously is better than either drug alone in reducing the incidence of PONV in female patients after middle ear surgery.

    Full Text Available The Transdermal Drug Delivery System (TDDS is one of the novel routes for systemic delivery of drugs through intact skin. A transdermal patch (TP is a medicated patch that is placed on skin for delivery of medication through skin into the blood stream. The aim of present study was to formulate and evaluate a Unani transdermal patch that could be used for antiemetic therapy. The incorporation of Unani ingredients, namely, Khardal (Brassica nigra, Zanjabeel (Zingiber officinale, Podina (Mentha arvensis, and Sirka (Vinegar were envisaged. The TP was prepared by solvent evaporation technique and was evaluated for organoleptic characteristics and other physicochemical properties, such as thickness, weight uniformity, folding endurance, moisture content, drug content, and tolerability and acceptability of patch. The in vitro permeation study of the patch was carried out through Franz diffusion cell using egg shell membrane as barrier membrane. Phosphate buffer pH 7.4 was used as dissolution medium and the temperature was maintained at 37 ± 1°C. The in vitro permeation study of the prepared TP indicated a time dependent increase in drug release throughout the study. The percentage of cumulative drug release was found to be 77.38% in 24 hours. The study shows a new approach to work in Unani pharmaceutics.

    This study is aimed at determining the efficacy of Mentha spicata (M. spicata) and Mentha × piperita (M. × piperita) in preventing chemotherapy-induced nausea and vomiting (CINV). This was a randomised, double-blind clinical trial study. Prior to the study, patients were randomly assigned into four groups to receive M. spicata or M. × piperita. Statistical analysis included the χ(2) test, relative risk, and Student's t-test. Fifty courses were analysed for each group that met our eligibility criteria. The treatment and placebo groups applied essential oils of M. spicata, M. × piperita, or a placebo, while the control group continued with their previous antiemetic regimen. Patients or guardians recorded the number of emetic events, the intensity of nausea over 20 h of chemotherapy, as well as any possible adverse effects that occurred during this time. There was a significant reduction in the intensity and number of emetic events in the first 24 h with M. spicata and M. × piperita in both treatment groups (p spicata or M. × piperita essential oils are safe and effective for antiemetic treatment in patients, as well as being cost effective.

    An increasing number of women are diagnosed with cancer during pregnancy and lactation. Women are usually advised to interrupt breastfeeding during systemic anticancer treatment for fear of serious adverse effects to the nursed infant. However, the issue is poorly addressed in the literature and very few studies have evaluated the safety of breastfeeding during or after cytotoxic drugs or target agents administration. In this review we will analyze the available evidence that addresses the issue of anticancer drugs, targeted agents, antiemetics and growth-factors excretion in human milk. This could serve as a unique resource that may aid physicians in the management of breastfeeding cancer patients interested in maintaining lactation during treatment. Copyright © 2012 Elsevier Ltd.

    A variety of triple antiemetic regimens are being used to prevent cisplatin-based chemotherapy induced delayed emesis and nausea in cancer patients. We performed a network meta-analysis to compare the efficacies of the different regimens. Electronic searches of the PubMed, Cochrane Library and MEDLINE databases were performed to identify randomized controlled trials, and data were analyzed using JAGS, Stata 14.0 and R project. The primary outcome was a complete response (CR). The secondary outcomes were no vomiting (NV) and no nausea (NN). Among the 398 studies identified, 10 were eligible and included, providing data on nine regimens. In the CR analysis, the absolute rank of netupitant + palonosetron + dexamethasone (NEPA) was 0.8579. In the NV and NN analyses, NEPA's absolute ranks were 0.8631 and 0.7902, respectively. The compliance of patients treated with rolapitant + granisetron + dexamethasone (RGD) was the best due to a low incidence of adverse events, and good compliance was also observed with NEPA. It was difficult to achieve good compliance with aprepitant + granisetron + dexamethasone (AGD). Overall, NEPA was the best regimen, and aprepitant + ondansetron + dexamethasone (AOD) is also worthy of recommendation because of its low cost and good effect. For patients with severe constipation, hiccups, asthenia and/or delayed nausea, RGD is worthy of consideration.

    To compare the efficacy of intravenous ondansetron (4 mg, 2 mL) and granisetron (2 mg, 2 mL) for preventing postoperative nausea and vomiting (PONV) in patients during oral and maxillofacial surgical procedures under general anesthesia. A prospective, randomized, and double blind clinical study was carried out with 60 patients undergoing oral and maxillofacial surgical procedures under general anesthesia. Patients were divided into two groups of 30 individuals each. Approximately two minutes before induction of general anesthesia, each patient received either 4 mg (2 mL) ondansetron or 2 mg (2 mL) granisetron intravenously in a double blind manner. Balanced anesthetic technique was used for all patients. Patients were assessed for episodes of nausea, retching, vomiting, and the need for rescue antiemetic at intervals of 0-2, 3, 6, 12, and 24 hours after surgery. Incidence of complete response and adverse effects were assessed at 24 hours postoperatively. Data was tabulated and subjected to statistical analysis using the chi-square test, unpaired t-test, or the Mann-Whitney U-test as appropriate. A P-value less than 0.05 was considered statistically significant. There was no statistically significant difference between the two groups for incidence of PONV or the need for rescue antiemetic. Both study drugs were well tolerated with minimum adverse effects; the most common adverse effect was headache. The overall incidence of complete response in the granisetron group (86.7%) was significantly higher than the ondansetron group (60.0%). Granisetron at an intravenous dose of 2 mg was found to be safe, well tolerated, and more effective by increasing the incidence of complete response compared to 4 mg intravenous ondansetron when used for antiemetic prophylaxis in maxillofacial surgery patients receiving general anesthesia. Benefits of granisetron include high receptor specificity and high potency, which make it a valuable alternative to ondansetron.

    Patients receiving platinum-based chemotherapy are at high risk of chemotherapy-induced nausea and vomiting (CINV), a distressing side effect of treatment. This post-hoc subgroup analysis of two pivotal trials evaluated the efficacy of NEPA in preventing CINV in subsets of patients with lung cancer who received cisplatin or carboplatin. In each study, the efficacy endpoints complete response (CR; defined as no emetic episodes and no rescue medication) and no significant nausea (NSN; defined as a score of  88% overall CR; carboplatin: > 75% overall CR), with higher CR rates for NEPA-treated patients than those receiving palonosetron; moreover, CR rates were sustained over multiple chemotherapy cycles (> 75%). High rates of NSN observed during cycle 1 (> 79%) were also maintained over multiple chemotherapy cycles. NEPA was well tolerated in all patients. NEPA appears to be effective and well tolerated in patients with lung cancer receiving platinum-based chemotherapy, across the acute, delayed, and overall phases and throughout multiple cycles. As a highly effective oral combination antiemetic agent administered as a single dose once per cycle, NEPA may offer a convenient, simplified prophylactic antiemetic.

    Antiemetic agent Meclizine HCl, widely prescribed in vertigo, is available only in immediate release dosage forms. The approved therapeutic dose and shorter elimination half-life make Meclizine HCl a potential candidate to be formulated in extended release dosage form. This study was aimed to develop extended release Meclizine HCl pellets by extrusion spheronization using natural and synthetic lipids. Influence of lipid type, drug/lipid ratio and combinations of different lipids on drug release and sphericity of pellets were evaluated. Thirty two formulations were prepared with four different lipids, Glyceryl monostearate (Geleol ® ), Glyceryl palmitostearate (Precirol ® ), Glyceryl behenate (Compritol ® ) and Carnauba wax, utilized either alone or in combinations of drug/lipid ratio of 1:0.5-1:3. Dissolution studies were performed at variable pH and release kinetics were analyzed. Fourier transform infrared spectroscopy was conducted and no drug lipid interaction was found. Sphericity indicated by shape factor (e R ) varied with type and concentration of lipids: Geleol ® (e R  = 0.891-0.997), Precirol ® (e R  = 0.611-0.743), Compritol ® (e R  = 0.665-0.729) and Carnauba wax (e R  = 0.499-0.551). Highly spherical pellets were obtained with Geleol ® (Aspect ratio = 1.005-1.052) whereas irregularly shaped pellets were formed using Carnauba wax (Aspect ratio = 1.153-1.309). Drug release was effectively controlled by three different combinations of lipids: (i) Geleol ® and Compritol ® , (ii) Geleol ® and Carnauba wax and (iii) Geleol ® , Compritol ® and Carnauba wax. Scanning electron microscopy of Compritol ® pellets showed smooth surface with pores, whereas, irregular rough surface with hollow depressions was observed in Carnauba wax pellets. Energy dispersive spectroscopy indicated elemental composition of lipid matrix pellets. Kinetics of (i) Geleol ® and Compritol ® pellets, explained by Korsmeyer-Peppas (R 2  = 0.978-0.993) indicated

    Chemotherapy-induced acute and delayed emesis involves the activation of multiple pathways, with 5-hydroxytryptamine (5-HT; serotonin) playing a major role in the initial response. Substance P tachykinin NK1 receptor antagonists can reduce emesis induced by disparate emetic challenges and therefore have a clinical utility as broad inhibitory anti-emetic drugs. In the present studies, we investigate the broad inhibitory anti-emetic profile of a relatively new NK1 receptor antagonist, netupitant, alone or in combination with the long acting 5-HT3 receptor antagonist, palonosetron, for a potential to reduce emesis in ferrets and shrews. Ferrets were pretreated with netupitant and/or palonosetron, and then administered apomorphine (0.125 mg/kg, s.c.), morphine (0.5 mg/kg, s.c.), ipecacuanha (1.2 mg/kg, p.o.), copper sulfate (100 mg/kg, intragastric), or cisplatin (5-10 mg/kg, i.p.); in other studies netupitant was administered to Suncus murinus before motion (4 cm horizontal displacement, 2 Hz for 10 min). Netupitant (3 mg/kg, p.o.) abolished apomorphine-, morphine-, ipecacuanha- and copper sulfate-induced emesis. Lower doses of netupitant (0.03-0.3 mg/kg, p.o.) dose-dependently reduced cisplatin (10 mg/kg, i.p.)-induced emesis in an acute (8 h) model, and motion-induced emesis in S. murinus. In a ferret cisplatin (5 mg/kg, i.p.)-induced acute and delayed emesis model, netupitant administered once at 3 mg/kg, p.o., abolished the first 24 h response and reduced the 24-72 h response by 94.6%; the reduction was markedly superior to the effect of a three times per day administration of ondansetron (1 mg/kg, i.p.). A single administration of netupitant (1 mg/kg, p.o.) plus palonosetron (0.1 mg/kg, p.o.) combined with dexamethasone (1 mg/kg, i.p., once per day), also significantly antagonized cisplatin-induced acute and delayed emesis and was comparable with a once-daily regimen of ondansetron (1 mg/kg, p.o.) plus aprepitant (1 mg/kg, p.o.) in combination with dexamethasone

    The purpose of this pilot study was to evaluate the acute gastrointestinal morbidity of adjuvant radiotherapy (RT) for Stage I seminoma of the testis. Ten Stage I patients receiving para-aortic and ipsilateral pelvic nodal (dog-leg) RT provided a toxicity baseline (group A). Twenty Stage I patients randomized to dog-let RT or para-aortic RT (10 per group) were further randomized to received prophylactic ondansetron or expectant therapy with metoclopramide (group B). Daily patient-completed questionnaires evaluated acute toxicity. Dog-leg RT for Stage I seminomas is associated with readily demonstrable gastrointestinal tract (GIT) toxicity. The number of patients in this study is too small to produce definitive results, but there appears to be reduced GIT toxicity with prophylactic antiemetics. The effect of reduced RT fields has been assessed further in the MRC randomized tiral of field sizes (TE10). (Author)

    Research on patient-reported outcomes indicates that constipation is a common adverse effect of chemotherapy, and the use of 5-hydroxytryptamine (serotonin; 5HT3) receptor antagonists aggravates this condition. As cancer patients take multiple drugs as a part of their clinical management, a non-pharmacological self-management (SM) of constipation would be recommended. We aimed to evaluate the effectiveness of a SM program on antiemetic-induced constipation in cancer patients. Thirty patients with breast cancer, receiving 5HT3 receptor antagonists to prevent emesis during chemotherapy were randomly assigned to the intervention or control group. The SM program consisted of abdominal massage, abdominal muscle stretching, and education on proper defecation position. The intervention group started the program before the first chemotherapy cycle, whereas patients in the wait-list control group received the program on the day before their second chemotherapy cycle. The primary outcome was constipation severity, assessed by the constipation assessment scale (CAS, sum of eight components). The secondary outcome included each CAS component (0-2 points) and mood states. A self-reported assessment of satisfaction with the program was performed. The program produced a statistically and clinically significant alleviation of constipation severity (mean difference in CAS, -3.00; P = 0.02), decrease in the likelihood of a small volume of stool (P = 0.03), and decrease in depression and dejection (P = 0.02). With regards to program satisfaction, 43.6 and 26.4 % patients rated the program as excellent and good, respectively. Our SM program is effective for mitigating the symptoms of antiemetic-induced constipation during chemotherapy.

  13. Eliminating Postoperative Nausea and Vomiting in Outpatient Surgery with Multimodal Strategies including Low Doses of Nonsedating, Off-Patent Antiemetics: Is “Zero Tolerance“ Achievable?

    Full Text Available For ondansetron, dexamethasone, and droperidol (when used for prophylaxis, each is estimated to reduce risk of postoperative nausea and/or vomiting (PONV by approximately 25%. Current consensus guidelines denote that patients with 0–1 risk factors still have a 10–20% risk of encountering PONV, but do not yet advocate routine prophylaxis for all patients with 10–20% risk. In ambulatory surgery, however, multimodal prophylaxis has gained favor, and our previously published experience with routine prophylaxis has yielded PONV rates below 10%. We now propose a “zero-tolerance” antiemetic algorithm for outpatients that involves routine prophylaxis by first avoiding volatile agents and opioids to the extent possible, using locoregional anesthesia, multimodal analgesia, and low doses of three nonsedating off-patent antiemetics. Routine oral administration (immediately on arrival to the ambulatory surgery suite of perphenazine 8 mg (antidopaminergic or cyclizine 50 mg (antihistamine, is followed by dexamethasone 4 mg i.v. after anesthesia induction (dexamethasone is avoided in diabetic patients. At the end of surgery, ondansetron (4 mg i.v., now off-patent is added. Rescue therapy consists of avoiding unnecessary repeat doses of drugs acting by the same mechanism: haloperidol 2 mg i.v. (antidopaminergic is prescribed for patients pretreated with cyclizine or promethazine 6.25 mg i.v. (antihistamine for patients having been pretreated with perphenazine. If available, a consultation for therapeutic acupuncture procedure is ordered. Our approach toward “zero tolerance” of PONV emphasizes liberal identification of and prophylaxis against common risks.

    Chemotherapy-induced nausea and vomiting (CINV) are major adverse effects of chemotherapy. Ginger has been used in postoperative and pregnancy-induced nausea and vomiting. Data on its utility in reducing CINV in children and young adults are lacking. Sixty chemotherapy cycles of cisplatin/doxorubicin in bone sarcoma patients were randomized to ginger root powder capsules or placebo capsules as an additional antiemetic to ondensetron and dexamethasone in a double-blind design. Acute CINV was defined as nausea and vomiting occurring within 24 hr of start of chemotherapy (days 1-4) and delayed CINV as that occurring after 24 hr of completion of chemotherapy (days 5-10). CINV was evaluated as per Edmonton's Symptom Assessment Scale and National Cancer Institute criteria respectively. Acute moderate to severe nausea was observed in 28/30 (93.3%) cycles in control group as compared to 15/27 (55.6%) cycles in experimental group (P = 0.003). Acute moderate to severe vomiting was significantly more in the control group compared to the experimental group [23/30 (76.7%) vs. 9/27 (33.33%) respectively (P= 0.002)]. Delayed moderate to severe nausea was observed in 22/30 (73.3%) cycles in the control group as compared to 7/27 (25.9%) in the experimental group (P < 0.001). Delayed moderate to severe vomiting was significantly more in the control group compared to the experimental group [14/30 (46.67%) vs. 4/27 (14.81%) (P = 0.022)]. Ginger root powder was effective in reducing severity of acute and delayed CINV as additional therapy to ondensetron and dexamethasone in patients receiving high emetogenic chemotherapy (ClinicalTrials.gov identifier: NCT00940368).

    Chemotherapy-induced nausea and vomiting is ranked among the worst side effects of chemotherapy. NEPA is an oral fixed-dose combination antiemetic under development, consisting of netupitant 300 mg, a highly selective NK1 receptor antagonist (RA), and palonosetron 0.5 mg, a pharmacologically and clinically distinct 5-HT3 RA. Although palonosetron is not associated with relevant ECG effects, this study evaluated cardiovascular safety of netupitant in combination with palonosetron, as well as its tolerability. This randomised, placebo- and positively controlled study in 197 subjects included 4 treatment groups: placebo, 200 mg netupitant + 0.5 mg palonosetron (NEPA200/0.5), 600 mg netupitant + 1.5 mg palonosetron (NEPA600/1.5, a supratherapeutic dose), and 400 mg moxifloxacin. Assessments included a 24-h baseline ECG recording, followed by a single dose of treatment and ECG measurements for 2 days. Mean placebo-corrected time-averaged changes from baseline were similar in NEPA200/0.5 and NEPA600/1.5 groups primarily for individually heart rate-corrected QT interval (QTcI: +4.7 and +3.6 ms, respectively) and for heart rate (HR: -3.3 bpm and -3.0 bpm), PR interval (-0.4 ms and 0.2 ms), and QRS interval (1 ms and 0.5 ms). The time-matched analysis showed no upper confidence interval >10 ms, with no suggestion of a QTc effect by pharmacokinetic-pharmacodynamic modeling for parent/metabolites. Moxifloxacin showed the expected placebo-corrected change from baseline (+8.4 ms time average) and the expected profile to establish assay sensitivity. No new morphologic changes of clinical relevance were observed. Treatment-related adverse events were comparable among groups. This study showed that NEPA treatments produced no significant effects on QTcI, HR, PR interval, QRS interval, and cardiac morphology relative to placebo, even at supratherapeutic doses.

    In 0.1 mol L-1 HCl medium, antiemetic drugs (ATM), such as granisetron hydrochloride (GS) and tropisetron hydrochloride (TS), reacted with H3PW12O40·nH2O and formed 3:1 ion-association complex of [(ATM)3PW12O40], then self-aggregated into nanoparticles-[(ATM)3PW12O40]n with an average size of 100 nm. The reaction resulted in the enhancement of resonance Rayleigh scattering (RRS) and the absorption spectra. The increments of scattering intensity (ΔIRRS) and the change of absorbance (ΔA) were both directly proportional to the concentrations of ATM in certain ranges. Accordingly, two new RRS and spectrophotometric methods were proposed for ATM detection. The detection limits (3σ) of GS and TS were 3.2 ng mL-1 and 4.0 ng mL-1(RRS method), 112.5 ng mL-1 and 100.0 ng mL-1(spectrophotometric method). These two methods were applied to determine GS in orally disintegrating tablets and the results were in good agreement with the official method. The ground-state geometries and electronic structures of GS and TS were optimized by the hybrid density functional theory (DFT) method and the shape of [(ATM)3PW12O40]n was characterized by atomic force microscopy (AFM). Take the RRS method with higher sensitivity as an example, the reaction mechanism and the reasons for enhancement of scattering were discussed.

    The interaction between two non-psychotropic cannabinoids, cannabidiol (CBD) and cannabigerol (CBG), which have been reported to act as a 5-hydroxytryptamine 1A (5-HT(1A)) agonist and antagonist, respectively, was evaluated. To evaluate the potential of CBG to reverse the anti-nausea, anti-emetic effects of CBD. In experiment 1, rats were pre-treated with CBG (0.0, 1, 5, and 10 mg/kg, ip), 15 min prior to being treated with CBD (experiment 1a: VEH or 5 mg/kg, ip) or 8-OH-DPAT (experiment 1b: VEH or 0.01 mg/kg, ip). Thirty minutes later, all rats received a pairing of 0.1% saccharin solution and LiCl (20 ml/kg of 0.15 M, ip). Seventy-two hours later, the rats received a drug-free taste reactivity test with saccharin to evaluate the effects of the treatments on the establishment of conditioned gaping reactions (a model of nausea). As well, conditioned saccharin avoidance was measured. In experiment 2, Suncus murinus were injected with CBG (5 mg/kg, ip) or VEH 15 min prior to CBD (5 mg/kg) or VEH and 30 min later were injected with LiCl (60 ml/kg of 0.15 M, i.p.), and the number of vomiting episodes were measured. CBD (5 mg/kg) suppressed conditioned gaping in rats and vomiting in shrews, which were reversed by pre-treatment with all doses of CBG. CBG also prevented the anti-nausea effects of 8-OH-DPAT. Interactions between moderate doses of CBG and CBD may oppose one another at the 5-HT(1A) receptor in the regulation of nausea and vomiting.

    Co-administration of multiple antiemetics that inhibit several molecular pathways involved in emesis is required to optimize chemotherapy-induced nausea and vomiting (CINV) control in patients receiving highly emetogenic chemotherapy (HEC). NEPA, a fixed combination of a highly selective NK1 receptor antagonist, netupitant (300 mg), and the pharmacologically distinct 5-HT3RA, palonosetron (PALO 0.50 mg), has shown superior CINV prevention compared with PALO in cisplatin and anthracycline/cyclophosphamide-based settings. This study is the first head-to-head comparison of NEPA versus an aprepitant (APR)/granisetron (GRAN) regimen. This randomized, double-blind phase III study conducted in Asia was designed with the primary objective to demonstrate non-inferiority of a single oral dose of NEPA compared with a 3-day oral APR/GRAN regimen in chemotherapy-naïve patients receiving cisplatin-based HEC. All patients also received oral dexamethasone (DEX) on days 1-4. The primary efficacy endpoint was complete response (CR: no emesis/no rescue medication) during the overall (0-120 h) phase. Non-inferiority was defined as a lower 95% CI greater than the non-inferiority margin set at - 10%. Secondary efficacy endpoints included no emesis, no rescue medication, and no significant nausea (NSN). Treatment groups were comparable for the 828 patients analyzed: predominantly male (71%); mean age 54.5 years; ECOG 0-1 (98%); lung cancer (58%). NEPA demonstrated non-inferiority to APR/GRAN for overall CR [NEPA 73.8% versus APR/GRAN 72.4%, 95% CI (-4.5%, 7.5%)]. No emesis [NEPA 75.0% versus APR/GRAN 74.0%, 95% CI (-4.8%, 6.9%)] and NSN rates [NEPA 75.7% versus APR/GRAN 70.4%, 95% CI (-0.6%, 11.4%)] were similar between groups, but significantly more NEPA patients did not take rescue medication [NEPA 96.6% versus APR/GRAN 93.5%, 95% CI (0.2%, 6.1%)]. NEPA was well tolerated with a similar safety profile to APR/GRAN. In this first study comparing NK1RA regimens and DEX, NEPA

    Full Text Available Rhus verniciflua Stoke has been commonly used in traditional medicine to treat gastrointestinal (GI dysfunction diseases. In order to investigate pharmacological properties of Rhus verniciflua Stoke water extract (RVX on cisplatin-induced amnesia, RVX (0, 25, 50, or 100 mg/kg was orally administrated for five consecutive days after a single intraperitoneal injection of cisplatin (6 mg/kg to SD rat. Cisplatin injection significantly increased the kaolin intake (emesis but reduced the normal diet intake (anorexia whereas the RVX treatment significantly improved these abnormal diet behaviors at both the acute and delayed phase. The serotonin concentration and the related gene expressions (5-HT3 receptors and SERT in small intestine tissue were abnormally altered by cisplatin injection, which were significantly attenuated by the RVX treatment. Histological findings of gastrointestinal tracts, as well as the proteins level of proinflammatory cytokines (TNF-α, IL-6, and IL-1β, revealed the beneficial effect of RVX on cisplatin-induced gastrointestinal inflammation. In addition, RVX significantly improved cisplatin-induced myelosuppression, as evidenced by the observation of leukopenia and by histological examinations in bone marrow. Our findings collectively indicated Rhus verniciflua Stoke improved the resistance of rats to chemotherapy-related adverse effects in the gastrointestinal track and bone marrow.

    Most patients who undergo chemotherapy have noted that nausea and vomiting are the most feared and distressing side-effects of cancer treatment (1). Nausea and vomiting from chemotherapy can be classified as acute, delayed, or anticipatory. Acute emesis generally occurs within 24 hours of chemotherapy administration; while delayed nausea and vomiting begin 24 hours after chemotherapy and may continue for up to one week. Anticipatory emesis occurs prior to chemotherapy in patients who anticipate another episode by sight, odors or memory of the place where acute nausea and vomiting occurred (2, 3). Different neurotransmitters found in the gastrointestinal tract (GIT) and central nervous system (CNS) mediate the pathophysiology of chemotherapy induced nausea and vomiting (CINV). These include dopamine, histamine, acetycholine, serotonin, and substance P; which act directly and indirectly on the vomiting center located in the lateral reticular formation of the medulla (1, 4). Substance P is a member of the tachykinins family of neuropeptides. The biological activity of this substance is to induce vomiting mediated by neurokinin-1 (NK1) receptors located primarily in the GIT and the CNS (5). Both Nk1 receptors and substance P play a significant role in the pathogenesis of acute and delayed CINV. (author)

    Specifically, our result indicates unacceptably high levels of aluminum in Eko and Omumu (>10-fold greater than the highest desirable levels set by the USEPA. The aluminum concentrations were influenced by the pH condition in which the samples were digested. Dietary exposure to aluminum at such high levels may be deleterious to maternal health and fetal development. Therefore consumption of Eko and Omumu as an antidote to reduce nausea during pregnancy should be discouraged. Future studies are planned to investigate specific impacts on fetal and maternal health and likely teratogenicity in rodent models.

    Chemotherapy-induced nausea and vomiting (CINV) is a common, distressing, debilitating and costly side effect, experienced by up to 90% of patients receiving highly emetogenic drugs. During the last 20 years great advances have been made in the prevention and treatment of CINV. Aprepitant (a neurokinin-1 antagonist) and palonosetron (a 5-HT3 antagonist) are the most recent additions to the available armamentarium. The aim of this paper is to review the most recent findings concerning the pathophysiology and prevention of CINV, and the international guidelines currently in place for its prevention and treatment. Among the treatments available, 5-HT3 antagonists and NK-1 antagonists are compared. In a large meta-analysis (8 studies in 3 592 patients) statistically significant differences in favour of palonosetron compared with first-generation 5-HT3 antagonists have been demonstrated in the prevention of acute, delayed and overall CINV. A recent, large phase III randomized, gender-stratified, double-blind trial in 848 patients receiving a broad range of moderately emetogenic chemotherapy regimens with a variety of tumour types showed superiority of an aprepitant triple regimen compared to a control regimen of ondansetron and dexamethasone. A new combined 5-HT3/ NK-1 treatment, called NEPA (palonosetron/netupitant), has provided very promising preliminary data and is awaited with great anticipation by clinicians. The specific Belgian situation in terms of Health Authorities recommendations and reimbursement policies is also presented. It is concluded that further improvements are still desirable, particularly in the prevention and treatment of delayed emesis.

    In a prospective, double-blinded, randomized trial, we evaluated the efficacy of IV (a) dexamethasone 8 mg, (b) ondansetron 8 mg, and (c) dexamethasone 8 mg plus ondansetron 4 mg for the prevention of postoperative nausea, vomiting (PONV), and pruritus in 130 (ASA physical status I to III) patients undergoing elective major orthopedic surgery after spinal anesthesia with hyperbaric 0.5% bupivacaine and intrathecal morphine. After spinal anesthesia, patients were randomized to one of three groups. Failure of PONV prophylaxis in the 24-h postoperative period occurred more frequently in patients who received dexamethasone alone (29 of 40; 73%) compared with those who received either ondansetron alone (23 of 47; 49%) (P = 0.02) or dexamethasone plus ondansetron together (19 of 43; 44%)(P = 0.01). There was no difference in the incidence of failure of prophylaxis of pruritus (70%, 72%, and 70% in dexamethasone 8 mg, ondansetron 8 mg, and dexamethasone 8 mg plus ondansetron 4 mg, respectively) (P > 0.1) in the 24-h postoperative period. We conclude that the administration of dexamethasone 8 mg with ondansetron 4 mg has no added benefit compared with ondansetron 8 mg alone in the prophylaxis of PONV and pruritus. IMPLICATIONS: Postoperative nausea and vomiting (PONV) and pruritus are common side effects after spinal opioid administration. In this study, dexamethasone 8 mg plus ondansetron 4 mg was as effective as ondansetron 8 mg. The administration of dexamethasone alone was associated with a frequent incidence of PONV, demonstrating a lack of efficacy. This has important cost implications.

    1987-07-01

    The antiaversive effect of mu-, kappa- and delta-opioid receptor agonists against conditioned taste aversion (CTA) induced by apomorphine, lithium chloride and copper sulphate in the rat was studied, in order to evaluate whether prevention of CTA is a suitable model for the study of antiemetics. Anti-aversion was not a general characteristic of all opioid substances tested. Only one dose of the mu-agonist morphine and only one dose of the kappa-agonist ethylketocyclazocine had a consistent antiaversive effect against CTA induced by apomorphine; one dose of the delta-agonist [D-Ala2, Met5]enkephalinamide antagonized the aversion induced by lithium chloride. As the results do not correspond to our previous findings on the antiemetic effects of these opioids in the dog (all mu- and kappa-agonists tested having an antiemetic effect), we conclude that the CTA test cannot be used as a screening test for potentially antiemetic drugs.

    Chemotherapy-induced nausea and vomiting (CINV) is associated with a significant deterioration in quality of life and is perceived by patients as a major adverse effect of the treatment. This review summarizes the safety and efficacy of current antiemetic agents for the prevention of CINV in children. Information on antiemetic prophylaxis for CINV in children was obtained from a literature review of current peer-reviewed articles and recent international guidelines. The literature review and the international antiemetic guidelines provide recommendations for use of specific antiemetics in children based on the emetogenicity of the chemotherapy. 5-Hydroxytryptamine-3 (5-HT 3 ) receptor antagonists have been safe and effective in the prevention of acute emesis with a few patients experiencing mild headache. No adequate studies have been conducted to date for specific recommendations for the prevention of delayed nausea and vomiting in children. The neurokinin (NK)- 1 receptor antagonist aprepitant has been approved by the US FDA for use in children of a specific age and weight. No studies for the NK 1 receptor antagonists netupitant and rolapitant in children have been conducted. Olanzapine, an antipsychotic, has been shown to be safe and effective in preventing nausea and emesis in adult patients receiving chemotherapy. Its use in children has been limited to children with poor control of CINV; more studies are necessary in this population. In conclusion, practitioners should follow international antiemetic guidelines to provide patients with the specific antiemetics in the recommended dose for the highest possible quality of care.

    Despite significant progress in the prevention of chemotherapy-induced nausea and vomiting (CINV) with the introduction of new antiemetic agents, 30–50% of patients receiving moderately or highly emetogenic chemotherapy (MEC or HEC) and guideline directed prophylactic antiemetics develop breakthrough CINV. International guidelines recommend the treatment of breakthrough CINV with an agent from a drug class that was not used in the prophylactic antiemetic regimen and recommend using the breakthrough medication continuously rather than using it on an as needed basis. There have been very few studies on the treatment of breakthrough CINV. A recent double-blind, randomized, phase III study suggested that olanzapine may be an effective agent for the treatment of breakthrough CINV. Refractory CINV occurs when patients develop CINV during subsequent cycles of chemotherapy when antiemetic prophylaxis has not been successful in controlling CINV in earlier cycles. Patients who develop refractory CINV should be considered for a change in their prophylactic antiemetic regimen. If significant anxiety exists, a benzodiazepine may be added to the prophylactic regimen. If a refractory patient is receiving HEC, olanzapine may be added to the prophylactic regimen. If the patient is receiving MEC, olanzapine or an NK-1 receptor antagonist may be added to the prophylactic regimen. PMID:26421294

    Full Text Available Gabapentin is well known for its pain control and antiepileptic effect, but its antiemetic effect is poorly investigated. Here we report on effective gabapentin use for refractory vomiting after craniotomy in two children with medulloblastoma in the fourth ventricle. The two pediatric patients (an 11-year-old girl and a 4-year-old boy underwent near-total excision of the tumor via craniotomy. Both patients suffered from refractory postoperative nausea and vomiting, treated with multiple traditional antiemetic drugs but without relief. After gabapentin intake, their nausea and vomiting improved from one to two episodes per day to complete resolution of symptoms. This report suggests that gabapentin may be a novel antiemetic therapeutic intervention for patients with refractory nausea and vomiting after craniotomy.

To prevent acute emesis, antiemetics should be administered just before chemotherapy and patients should be protected for up to 24 hours after chemotherapy initiation. The emetogenic potential of chemotherapeutic agents guides clinicians towards the most appropriate antiemetic prophylaxis. Current guidelines recommend the use of 5-HT3 receptor antagonist (RA either alone or in combination with dexamethasone and/or a neurokinin-1 RA both in the acute and delayed phases. The second-generation 5-HT3RA palonosetron exhibits a longer half-life and a higher binding affinity than older antagonists. Palonosetron has been approved by the FDA for the prevention of chemotherapy-induced nausea and vomiting (CINV in patients scheduled to receive either moderately (MEC or highly emetogenic chemotherapy (HEC and for the prevention of delayed CINV in patients receiving MEC. The present review will discuss the role of palonosetron in the prevention of acute CINV.Keywords: antiemetics, chemotherapy, nausea, vomiting, serotonin-receptor antagonists, palonosetron

    2015-12-01

    Many patients undergoing moderately or highly emetogenic chemotherapy experience chemotherapy-induced nausea/vomiting (CINV) and report reduced daily functioning, despite prophylaxis with antiemetic drugs. While modern antiemetics have largely alleviated acute emesis, management of nausea and delayed emesis remains particularly challenging. We briefly review the pathophysiologic mechanisms of CINV and the clinical impact of current antiemetics, i.e., the serotonin subtype 3 (5-HT3) receptor antagonists (RAs) and neurokinin-1 (NK1)RAs, before summarizing recent data from clinical trials of new agents. The new antiemetics reviewed include the two most recently approved drugs, the NK1RA rolapitant and the fixed-dose combination product, NEPA, which is composed of the NK1RA netupitant and the 5-HT3RA palonosetron. Phase 3 studies demonstrate improved control of CINV in the delayed and overall phases when rolapitant is added to a standard 5-HT3RA regimen. Phase 2 and phase 3 clinical trials with NEPA demonstrate improved control of CINV in the acute, delayed, and overall phases vs. 5-HT3RA regimens. These data suggest that delayed emesis can be substantially reduced via combined 5-HT3 and NK1 receptor neurotransmitter pathway inhibition. Copyright © 2015 Elsevier Ltd. All rights reserved.

  13. Recent developments in the prevention of chemotherapy-induced nausea and vomiting (CINV): a comprehensive review.

    2015-06-01

    The prevention of chemotherapy-induced nausea and vomiting (CINV) has been revolutionized over the past 25 years. Guideline-based treatment means that vomiting can be prevented in the majority, but not in all patients. Therefore, antiemetic research continues with the goal of optimizing CINV control for all patients. This comprehensive review summarizes the research efforts in this field over the past few years. Emerging from this research are two new antiemetic agents, netupitant/palonosetron, the first antiemetic combination agent and rolapitant, a new NK1RA. In addition, studies have evaluated the benefits of olanzapine and ginger, explored optimal combinations of agents for delayed CINV prevention, confirmed that dexamethasone-sparing regimens are effective, and demonstrated the value of NK1RAs in high-dose chemotherapy settings as well as with certain moderately emetogenic chemotherapies such as carboplatin. Research has also validated the correlation between antiemetic guideline adherence and improved CINV control. Finally, regulatory authorities have utilized extreme caution in retiring some 5-HT3RAs or decreasing their maximum dose. © The Author 2015.

It causes significant mortality in developing countries and significant economic burden to developed countries. Viruses are ­responsible for approximately 70% of episodes of acute gastroenteritis in children and rotavirus is one of the best studied of these viruses. Oral rehydration therapy is as effective as i­ntravenous therapy in treating mild to moderate dehydration in acute gastroenteritis and is strongly r­ecommended as the first line therapy. However, the oral rehydration solution is described as an underused simple solution. Vomiting is one of the main reasons to explain the underuse of oral rehydration therapy. Antiemetics are not routinely recommended in treating acute gastroenteritis, though they are still commonly prescribed. Ondansetron is one of the best studied antiemetics and its role in enhancing the compliance of oral rehydration therapy and decreasing the rate of hospitalization has been proved recently. The guidelines regarding the recommendation on antiemetics have been changed according to the evidence of these recent studies.Keywords: gastroenteritis, vomiting, antiemetic, ondansetron, rotavirus, oral rehydration therapy, intravenous therapy, guideline

    Petra Feyer

    2015-01-01

    Full Text Available The incidence of nausea and vomiting after radiotherapy is often underestimated by physicians, though some 50–80% of patients may experience these symptoms. The occurrence of radiotherapy-induced nausea and vomiting (RINV will depend on radiotherapy-related factors, such as the site of irradiation, the dosing, fractionation, irradiated volume, and radiotherapy techniques. Patients should receive antiemetic prophylaxis as suggested by the international antiemetic guidelines based upon a risk assessment, taking especially into account the affected anatomic region and the planned radiotherapy regimen. In this field the international guidelines from the Multinational Association of Supportive Care in Cancer (MASCC/European Society of Medical Oncology (ESMO and the American Society of Clinical Oncology (ASCO guidelines as well as the National Comprehensive Cancer Network (NCCN are widely endorsed. The emetogenicity of radiotherapy regimens and recommendations for the appropriate use of antiemetics including 5-hydroxytryptamine (5-HT3 receptor antagonists, steroids, and other antiemetics will be reviewed in regard to the applied radiotherapy or radiochemotherapy regimen.

  8. The involvement of TRPV1 in emesis and anti-emesis.

    2015-01-01

    Diverse transmitter systems (e.g. acetylcholine, dopamine, endocannabinoids, endorphins, glutamate, histamine, 5-hydroxytryptamine, substance P) have been implicated in the pathways by which nausea and vomiting are induced and are targets for anti-emetic drugs (e.g. 5-hydroxytryptamine3 and tachykinin NK1 antagonists). The involvement of TRPV1 in emesis was discovered in the early 1990s and may have been overlooked previously as TRPV1 pharmacology was studied in rodents (mice, rats) lacking an emetic reflex. Acute subcutaneous administration of resiniferatoxin in the ferret, dog and Suncus murinus revealed that it had "broad-spectrum" anti-emetic effects against stimuli acting via both central (vestibular system, area postrema) and peripheral (abdominal vagal afferents) inputs. One of several hypotheses discussed here is that the anti-emetic effect is due to acute depletion of substance P (or another peptide) at a critical site (e.g. nucleus tractus solitarius) in the central emetic pathway. Studies in Suncus murinus revealed a potential for a long lasting (one month) effect against the chemotherapeutic agent cisplatin. Subsequent studies using telemetry in the conscious ferret compared the anti-emetic, hypothermic and hypertensive effects of resiniferatoxin (pungent) and olvanil (non-pungent) and showed that the anti-emetic effect was present (but reduced) with olvanil which although inducing hypothermia it did not have the marked hypertensive effects of resiniferatoxin. The review concludes by discussing general insights into emetic pathways and their pharmacology revealed by these relatively overlooked studies with TRPV1 activators (pungent an non-pungent; high and low lipophilicity) and antagonists and the potential clinical utility of agents targeted at the TRPV1 system.

The objective of this study was to define, from the UK payer perspective, the cost-effectiveness of an antiemetic regimen using aprepitant, a selective neurokinin-1 receptor antagonist, for patients receiving chemotherapy for breast cancer. Methods: A decision-analytic model was developed to compare an aprepitant regimen (aprepitant, ondansetron, and dexamethasone with a standard UK antiemetic regimen (ondansetron, dexamethasone, and metoclopramide for expected costs and health outcomes after single-day adjuvant chemotherapy for breast cancer. The model was populated with results from patients with breast cancer participating in a randomized trial of CINV preventative therapy for cycle 1 of single-day chemotherapy. Results: During 5 days after chemotherapy, 64% of patients receiving the aprepitant regimen and 47% of those receiving the UK comparator regimen had a complete response to antiemetic therapy (no emesis and no rescue antiemetic therapy. A mean of £37.11 (78% of the cost of aprepitant was offset by reduced health care resource utilization costs. The predicted gain in quality-adjusted lifeyears (QALYs with the aprepitant regimen was 0.0048. The incremental cost effectiveness ratio (ICER with aprepitant, relative to the UK comparator, was £10,847/QALY, which is well below the threshold commonly accepted in the UK of £20,000–£30,000/QALY. Conclusion: The results of this study suggest that aprepitant is cost-effective for preventing CINV associated with chemotherapy for patients with breast cancer in the UK health

    1998-01-01

    Background: A significant number of patients receiving radiotherapy experience the distressing side effects of emesis and nausea. These symptoms are some of the most distressing problems for the patients influencing their quality of life. Methods: International study results concerning radiotherapy-induced emesis are demonstrated. A German multicenter questionnaire examining the strategies to prevent or to treat radiotherapy-induced nausea and emesis is presented. An international analysis concerning incidence of emesis and nausea in fractionated radiotherapy patients is discussed. Finally the consensus of the consensus conference on antiemetic therapy from the Perugia International Cancer Conference V is introduced. Results: Untreated emesis can lead to complications like electrolyte disorders, dehydration, metabolic disturbances and nutrition problems with weight loss. Prophylactic antiemetics are often given to patients receiving single high-dose radiotherapy to the abdomen. A survey has revealed that antiemetic prophylaxis is not routinely offered to the patients receiving fractionated radiotherapy. However, there is a need for an effective treatment of emesis for use in this group of patients, too. In 20% of patients nausea and emesis can cause a treatment interruption because of an inadequate control of symptoms. Like in chemotherapy strategies there exist high, moderate, and low emetogenic treatment regimens in radiotherapy as well. The most emetogenic potential has the total body irradiation followed by radiotherapy to the abdomen. Radiotherapy induced emesis can be treated effectively with conventional antiemetics up to 50%. Conclusions: Studies with total body irradiation, fractionated treatment and high-dose single exposures have cleary demonstrated the value of 5-HT3-receptor antagonist antiemetics. There is a response between 60 and 97%. There is no difference in the efficacy of the different 5-HT3-antagonists. High-risk patients should be prophylactic

    The current antiemetic prophylaxis for patients treated with highly emetogenic chemotherapy (HEC) included the olanzapine-based triplet and neurokinin-1 receptor antagonists (NK-1RAs)-based triplet. However, which one shows better antiemetic effect remained unclear. We systematically reviewed 43 trials, involving 16,609 patients with HEC, which compared the following antiemetics at therapeutic dose range for the treatment of chemotherapy-induced nausea and vomiting: olanzapine, aprepitant, casopitant, fosaprepitant, netupitant, and rolapitant. The main outcomes were the proportion of patients who achieved no nausea, complete response (CR), and drug-related adverse events. A Bayesian network meta-analysis was performed. Olanzapine-based triple regimens showed significantly better no-nausea rate in overall phase and delayed phase than aprepitant-based triplet (odds ratios 3.18, 3.00, respectively), casopitant-based triplet (3.78, 4.12, respectively), fosaprepitant-based triplet (3.08, 4.10, respectively), rolapitant-based triplet (3.45, 3.20, respectively), and conventional duplex regimens (4.66, 4.38, respectively). CRs of olanzapine-based triplet were roughly equal to different NK-1RAs-based triplet but better than the conventional duplet. Moreover, no significant drug-related adverse events were observed in olanzapine-based triple regimens when compared with NK-1RAs-based triple regimens and duplex regimens. Additionally, the costs of olanzapine-based regimens were obviously much lower than the NK-1RA-based regimens. Olanzapine-based triplet stood out in terms of nausea control and drug price but represented no significant difference of CRs in comparison with NK-1RAs-based triplet. Olanzapine-based triple regimens should be an optional antiemetic choice for patients with HEC, especially those suffering from delayed phase nausea. According to the results of this study, olanzapine-based triple antiemetic regimens were superior in both overall and delayed

  14. 8-OH-DPAT suppresses vomiting in the cat elicited by motion, cisplatin or xylazine

    Science.gov (United States)

    Lucot, James B.; Crampton, George H.

    1989-01-01

    Vomiting was suppressed in cats pretreated with 8-OH-DPAT and then challenged with an emetic stimulus; motion, xylazine or cisplatin. The antiemetic effect is likely due to stimulation of postsynaptic serotonin-1A receptors. The most parsimonious explanation is that it acts at a convergent structure, presumably at or near the vomiting center. If so, 8-OH-DPAT may block emesis elicited by virtually any other stimulus. A supplementary experiment revealed that lorazepam suppressed motion sickness at a dose that produced ataxia, but did not suppress xylazine-induced emesis. These results do not support the possibility that the antiemetic effects of 8-OH-DPAT were the result of anxiolytic activity.

    Various recommendations exist for the treatment of nausea and vomiting in palliative care but only few studies and even less systematic reviews look into antiemetic therapy for patients receiving palliative care. This systematic review aims to analyze the current evidence for antiemetic treatment with 5HT3 receptor antagonists, steroids, antihistamines, anticholinergics, somatostatin analogs, benzodiazepines and cannabinoids in palliative care patients with far advanced cancer not receiving chemotherapy or radiotherapy, acquired immune deficiency syndrome (AIDS), chronic obstructive pulmonary disease (COPD), progressive heart failure, amyotrophic lateral sclerosis (ALS) or multiple sclerosis (MS). Results regarding evidence of treatment with prokinetic and neuroleptic agents will be published separately. The electronic databases PubMed and EmBase were systematically searched for studies (published 1966-2011) dealing with antiemetic therapy in palliative care and electronic retrieval was completed by manual searching. Studies with patients undergoing chemotherapy or radiotherapy, pediatric studies and studies published in languages other than English or German were excluded. Studies addressing therapy with 5HT3 receptor antagonists, steroids, antihistamines, anticholinergics, somatostatin analogs, benzodiazepines or cannabinoids were identified and selected for this systematic review. In the general search 75 relevant studies were found. Of those 36 addressed 5HT3 receptor antagonists, steroids, antihistamines, anticholinergics, somatostatin analogs, benzodiazepines and cannabinoids, 13 considered 5HT3 receptor antagonists, 10 somatostatin antagonists, 9 steroids, 5 cannabinoids, 4 anticholinergics, 1 antihistamines and none benzodiazepines. Furthermore six systematic reviews exist. Evidence for any drug used as an antiemetic is low. Concerning 5HT3 receptor antagonists data are insufficient for recommendations on the treatment of patients with AIDS and MS due to

    As a drug originally introduced for its anticonvulsant effects, gabapentin has been recently shown to be effective in the treatment of nausea and vomiting in various clinical settings. This study compared the antiemetic efficacy of oral gabapentin, intravenous ramosetron and gabapentin plus ramosetron in patients receiving fentanyl-based patient-controlled analgesia after laparoscopic gynecologic surgery. One hundred and thirty two patients undergoing laparoscopic gynecologic surgery under general anesthesia were allocated randomly into three groups: group G received 300 mg oral gabapentin 1 h before anesthesia, group R received 0.3 mg intravenous ramosetron at the end of surgery, and group GR received a combination of 300 mg oral gabapentin 1 h before anesthesia and 0.3 mg intravenous ramosetron at the end of surgery. Postoperative nausea, retching, vomiting, rescue antiemetic drug use, pain, rescue analgesic requirements and adverse effects were assessed at 0-2, 2-24 and 24-48 h after surgery. Postoperative nausea and vomiting (PONV) was defined as the presence of nausea, retching or vomiting. The incidence of complete response (no PONV and no rescue antiemetics up to 48 h postoperatively) was significantly higher in group GR (26/40, 65%) than group G (16/40, 40%; P = 0.025) and group R (18/44, 41%; P = 0.027), whereas there was no significant difference between group G and group R (P = 0.932). There were no significant between-group differences in the incidence of emetic episodes, use of rescue antiemetics, severe emesis, use of rescue analgesics or any adverse effects. Postoperative pain scores were also similar among groups. The combination with gabapentin and ramosetron is superior to either drug alone for prevention of PONV after laparoscopic gynecologic surgery.

    Arab scientists were various centuries ahead of our current knowledge of the curative power of hemp (Cannabis sativa L., Cannabaceae). Modem scientific literature ignores their contribution on the subject. We review in this paper the therapeutic uses of the plant in Arabic medicine from the 8th to the 18th century. Arab physicians knew and used its diuretic, anti-emetic, anti-epileptic, anti-inflammatory, pain-killing and antypiretic properties, among others.

    Purpose: A prospective observational multicentre trial was carried out to assess the incidence, pattern, and prognostic factors of radiation-induced emesis (RIE), and to evaluate the use of antiemetic drugs in patients treated with radiotherapy or concomitant radio-chemotherapy. The application in clinical practice of the Multinational Association of Supportive Care in Cancer guidelines was also studied. Materials and methods: Forty-five Italian radiation oncology centres took part in this trial. The accrual lasted for 3 consecutive weeks and only patients starting radiotherapy or concomitant radio-chemotherapy in this period were enrolled. Evaluation was based on diary card filled in daily by patients during treatment and one week after stopping it. Diary card recorded the intensity of nausea/vomiting and prophylactic/symptomatic antiemetic drug prescriptions. Results: A total of 1020 patients entered into the trial, and 1004 were evaluable. Vomiting and nausea occurred in 11.0% and 27.1% of patients, respectively, and 27.9% patients had both vomiting and nausea. In multifactorial analysis, the only statistically significant patient-related risk factors were concomitant chemotherapy and previous experience of vomiting induced by chemotherapy. Moreover, two radiotherapy-related factors were significant risk factors for RIE, the irradiated site (upper abdomen) and field size (>400 cm 2 ). An antiemetic drug was given only to a minority (17%) of patients receiving RT, and the prescriptions were prophylactic in 12.4% and symptomatic in 4.6%. Different compounds and a wide range of doses and schedules were used. Conclusions: These data were similar to those registered in our previous observational trial, and the radiation oncologists' attitude in underestimating RIE and under prescribing antiemetics was confirmed.

    Conclusion: Number of vomiting per day and maternal serum TSH levels could help physicians to estimate the risk of prolonged hospitalization; however further investigations are needed in large population studies. Identifying the high risk patients is important both for prevention of HEG and beginning appropriate antiemetic treatment to avoid complications to reduce the economic costs.

    Postoperative nausea and vomiting (PONV) is a common complication after craniotomy. Vomiting may be a potentially hazardous complication in neurosurgical patients. We compared the efficacy of fosaprepitant and droperidol for the prevention of PONV, vomiting in particular, after craniotomy. Patients scheduled to undergo elective craniotomy were enrolled in the study and randomly divided in a double-blind manner into two groups to receive either 150 mg of fosaprepitant (group F) or 1.25 mg of droperidol (group D). Dexamethasone (9.9 mg) was given to all patients, except those with diabetes mellitus. The incidence of PONV, frequency of vomiting, nausea score, and use of rescue antiemetic during the first 72 h after surgery were assessed at five time intervals (0-2, 2-6, 6-24, 24-48, and 48-72 h). Of the 200 randomized patients eligible for entry into the study, 186 were ultimately included for analysis. There were no significant differences in demographics or intraoperative variables between the two treatment groups. Over the entire 72-h post-craniotomy observation period the overall and cumulative incidence of vomiting was significantly lower in group F patients than in group D patients, while there were no between-group differences in the overall and cumulative incidence of PONV or in complete response (no PONV and no rescue antiemetic). The incidence and frequency of vomiting during each of the five observational periods were significantly lower in group F patients than group D patients, although there were no differences in the nausea score and antiemetic use between the groups. Based on the results, fosaprepitant was more effective than droperidol in the prevention of vomiting after craniotomy over the entire 72-h study period. However, there was no difference in the incidence of nausea and antiemetic use.

    Cisplatin is commonly used for esophageal and gastric cancer, but has a high emetic risk. Although the control of vomiting is favorable, nausea is still poorly controlled in patients receiving cisplatin-based regimens. The present study was designed to determine the risks for cisplatin-induced nausea. The effect of olanzapine, an antipsychotic drug, as an antiemetic for patients with risk of poor control of nausea was subsequently examined. The prevalence of antiemetic medication and the control of nausea and vomiting were retrospectively examined in patients with esophageal or gastric cancer receiving the first cycle of cisplatin-based chemotherapy. Risks for nausea were analyzed by multivariate logistic regression analysis, in which threshold for age and cisplatin dose wer assessed by receiver operating characteristic curve analysis. A total of 186 patients received cisplatin-based regimens during January 2011 and December 2016. Guideline-consistent antiemetic medication was administered to all patients. Although the rate of no vomiting was high (93%), the rate of non-significant (grade 2 or more) nausea was insufficient (64%) during the overall period. Risk analysis showed that cisplatin dose of 50 mg/m 2 or more and female gender were significant risks for nausea. Addition of olanzapine, but not of prochlorperazine, to the standard antiemetic medication was effective in suppressing nausea in patients who experienced nausea in the first cycle. Being female and cisplatin doses at 50 mg/m 2 or more were demonstrated to increase risk for nausea. Addition of olanzapine to the standard medication was effective in preventing nausea in high-risk patients with esophageal and gastric cancer.

    Full Text Available Background and Aims: Post-operative nausea and vomiting (PONV has an 80% incidence in high-risk patients. This is despite the availability of several antiemetic drugs. Selective 5-hydroxytryptamine type 3 (5-HT 3 receptor antagonists are considered first-line for prophylaxis, ondansetron being the most commonly used agent. Ramosetron, another selective 5-HT 3 receptor antagonist, is more potent and longer acting than ondansetron. This study was conducted to evaluate the antiemetic efficacy of ramosetron in comparison with ondansetron in patients at a high risk of PONV. Methods: This was a prospective randomised double-blind study carried out over a 6-month period in which 206 patients with at least two risk factors for PONV were randomised to receive ramosetron 0.3 mg or ondansetron 8 mg, 30 min before the end of surgery. The incidence of PONV, severity of nausea and need for rescue antiemetic were recorded over the next 24 h. Primary outcome was the incidence of PONV. Secondary outcomes included severity of nausea and need for rescue. The data were analysed using the Predictive Analytics Software (PASW, version 18: Chicago, IL, USA. Results: The incidence of PONV was found to be 35% in the ramosetron group as opposed to 43.7% in the ondansetron group (P = 0.199. Need for rescue antiemetic was 23.3% in the ramosetron group and 32% in the ondansetron group (P = 0.156 in the 24 h following surgery. Conclusion: Ramosetron 0.3 mg and ondansetron 8 mg were equally effective in reducing the incidence of PONV in high risk patients.

  11. The Effect of Transdermal Scopolamine for the Prevention of Postoperative Nausea and Vomiting

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available Postoperative nausea and vomiting is one of the most common and undesirable complaints recorded in as many as 70%-80% of high-risk surgical patients. The current prophylactic therapy recommendations for PONV management stated in the Society of Ambulatory Anesthesia guidelines should start with monotherapy and patients at moderate to high risk, a combination of antiemetic medication should be considered. Consequently, if rescue medication is required, the antiemetic drug chosen should be from a different therapeutic class and administration mode than the drug used for prophylaxis. The guidelines restrict the use of dexamethasone, transdermal scopolamine, aprepitant, and palonosetron as rescue medication 6 hours after surgery. In an effort to find a safer and reliable therapy for postoperative nausea and vomiting, new drugs with antiemetic properties and minimal side effects are needed, and scopolamine may be considered an effective alternative. Scopolamine is a belladonna alkaloid, α-(hydroxymethyl benzene acetic acid 9-methyl-3-oxa-9-azatricyclo non-7-yl ester, acting as a nonselective muscarinic antagonist and producing both peripheral antimuscarinic and central sedative, antiemetic, and amnestic effects. The empirical formula is C17H21NO4 and its structural formula is a tertiary amine L-(2-scopolamine (tropic acid ester with scopine; MW = 303.4. Scopolamine became the first drug commercially available as a transdermal therapeutic system used for extended continuous drug delivery during 72 hours. Clinical trials with transdermal scopolamine have consistently demonstrated its safety and efficacy in postoperative nausea and vomiting. Thus, scopolamine is a promising candidate for the management of postoperative nausea and vomiting in adults as a first line monotherapy or in combination with other drugs. In addition, transdermal scopolamine might be helpful in preventing postoperative discharge nausea and vomiting owing to its long

    Neuroleptics are antipsychotic drugs. In addition to their antipsychotic properties, many physicians use them as anti-anxiety or antiemetics. Indeed, most patients referred to psychiatrists would have been given one, or a combination, of these drugs. Physicians should therefore be aware of their side-effects. Abnormal involuntary movements, now recognized as side-effects of neuroleptics, are broadly classified as acute early occurring movement disorders and late appearing movement disorders. ...

    Full Text Available BACKGROUND: We investigated the effects of a novel method of anesthesia combining propofol and volatile anesthesia on the incidence of postoperative nausea and vomiting in patients undergoing laparoscopic gynecological surgery. METHODS: Patients were randomly divided into three groups: those maintained with sevoflurane (Group S, n = 42, propofol (Group P, n = 42, or combined propofol and sevoflurane (Group PS, n = 42. We assessed complete response (no postoperative nausea and vomiting and no rescue antiemetic use, incidence of nausea and vomiting, nausea severity score, vomiting frequency, rescue antiemetic use, and postoperative pain at 2 and 24 h after surgery. RESULTS: The number of patients who exhibited a complete response was greater in Groups P and PS than in Group S at 0-2 h (74%, 76% and 43%, respectively, p = 0.001 and 0-24 h (71%, 76% and 38%, respectively, p < 0.0005. The incidence of nausea at 0-2 h (Group S = 57%, Group P = 26% and Group PS = 21%, p = 0.001 and 0-24 h (Group S = 62%, Group P = 29% and Group PS = 21%, p < 0.0005 was also significantly different among groups. However, there were no significant differences among groups in the incidence or frequency of vomiting or rescue antiemetic use at 0-24 h. CONCLUSION: Combined propofol and volatile anesthesia during laparoscopic gynecological surgery effectively decreases the incidence of postoperative nausea. We term this novel method of anesthesia "combined intravenous-volatile anesthesia (CIVA".

    To provide information to help nurses mitigate cardiac risks among patients receiving romidepsin (Istodax®), a histone deacetylase (HDAC) inhibitor approved by the U.S. Food and Drug Administration for the treatment of relapsed/refractory cutaneous and peripheral T-cell lymphoma. 
. Clinical studies of romidepsin represented the primary data sources. Supporting references included class information on HDAC inhibitors, as well as data regarding the impact of electrolyte imbalances and antiemetic treatment on electrocardiogram (ECG) data.
. Cardiac concerns during treatment with romidepsin are multifactorial. Electrolyte deficiencies, which are associated with ECG abnormalities and dysrhythmias, are common among patients with T-cell lymphoma. In addition, clinically insignificant changes in the corrected QT interval reported with romidepsin are primarily attributable to concomitant use of prophylactic antiemetics and likely exaggerated by transient increases in heart rate. 
. Data support the cardiac safety of romidepsin while cautioning about the need for nurses' vigilance regarding consistent electrolyte supplementation, appropriate antiemetic selection, and heart rate monitoring. 
. By recognizing drug-related and non-drug-related influences on cardiac safety during treatment with romidepsin, as well as other anticancer agents, nurses can identify risks, report them, and recommend appropriate interventions, which, ultimately, facilitates improved patient outcomes.

    Prevention of nausea and vomiting is the main goal of antiemetic treatment in cancer patients scheduled to receive chemotherapy. To prevent acute emesis, antiemetics should be administered just before chemotherapy and patients should be protected for up to 24 hours after chemotherapy initiation. The emetogenic potential of chemotherapeutic agents guides clinicians towards the most appropriate antiemetic prophylaxis. Current guidelines recommend the use of 5-HT 3 receptor antagonist (RA) either alone or in combination with dexamethasone and/or a neurokinin-1 RA both in the acute and delayed phases. The second-generation 5-HT 3 RA palonosetron exhibits a longer half-life and a higher binding affinity than older antagonists. Palonosetron has been approved by the FDA for the prevention of chemotherapy-induced nausea and vomiting (CINV) in patients scheduled to receive either moderately (MEC) or highly emetogenic chemotherapy (HEC) and for the prevention of delayed CINV in patients receiving MEC. The present review will discuss the role of palonosetron in the prevention of acute CINV

    STUDY OBJECTIVES: To compare the prophylactic antiemetic efficacy of the combination of ondansetron and droperidol with that of droperidol alone in patients undergoing elective laparoscopic cholecystectomy. DESIGN: Randomized, double-blind controlled trial. University affiliated teaching hospital after induction of standardized general anesthesia. PATIENTS: 64 ASA physical status I or II patients aged 18 to 80 years, undergoing elective laparoscopic cholecystectomy. INTERVENTION: Following induction of general anesthesia, patients received either droperidol 1.25 mg intravenously (IV; n = 30; Group D) or the combination of droperidol 1.25 mg IV and ondansetron 4 mg IV (n = 34; Group D+O). MEASUREMENTS: Number and severity of nausea episodes, number of emetic episodes, total analgesic consumption, and rescue antiemetic administration were assessed at 1, 3, and 24 hours after admission to the recovery room. Data were analyzed using Fisher\\'s Exact test and unpaired Student\\'s t-test; a p-value <0.05 was considered significant. RESULTS: The proportions of patients who experienced nausea (70% and 53% for D and D+O groups, respectively) and vomiting (30% and 19% for D and D+O groups, respectively) were similar in the two groups. The frequency of moderate and severe nausea (requiring administration of antiemetic) was less in group D + O (7%) compared with group D (19%; p < 0.05). CONCLUSIONS: Patients who received the combination of droperidol and ondansetron experienced less severe nausea compared with patients who received droperidol alone.

    Chemotherapy-induced nausea and vomiting (CINV) has long been one of the most troublesome adverse effects of chemotherapy, leading to significant detriments in quality of life and functioning, increased economic costs, and, in some cases, the discontinuation of effective cancer therapy. The past 2 decades have witnessed a dramatic increase in the number of effective antiemetic agents, with the introduction of the serotonin (5-hydroxytryptamine [5-HT₃]) receptor antagonists (ondansetron, granisetron, and palonosetron), the neurokinin-1 (NK₁) receptor antagonists (aprepitant and fosaprepitant), and the identification of other agents that have demonstrated efficacy against CINV, including corticosteroids. These agents often provide excellent control of emesis. Nausea, however, has proven more intractable, particularly in the days after administration of chemotherapy. Newer antiemetic agents under study may provide additional CINV control, particularly against delayed nausea. New agents undergoing review by the US Food and Drug Administration for the prevention of CINV include the novel NK₁ receptor antagonist rolapitant and a fixed-dose combination consisting of the novel NK₁ receptor antagonist netupitant and palonosetron (NEPA). Adherence to clinical practice guidelines has been shown to significantly improve CINV control. As antiemetic therapy continues to evolve, it will be important for clinicians to stay informed of new developments and changes in guidelines.

    Chemotherapy-induced nausea and vomiting (CINV) remains one of the most challenging adverse events of chemotherapy, and one that has substantial negative effects on patients, clinicians, and the wider health care system. Use of CINV prophylaxis consistent with clinical practice guidelines is essential for attaining optimal CINV control. In recent years, there has been a dramatic improvement in the control of CINV with the introduction of effective antiemetic agents, including the serotonin (5-hydroxytryptamine [5-HT3]) receptor antagonists (ondansetron, granisetron, and palonosetron) and the neurokinin-1 (NK1) receptor antagonists (aprepitant and fosaprepitant). An important benefit of the newer antiemetic agents is their improved ability to control the delayed CINV that can develop in the days after chemotherapy administration. In October 2014, a fixed-dose oral combination containing the novel NK1 receptor antagonist netupitant and palonosetron (NEPA) received approval from the US Food and Drug Administration. The combination of 2 effective antiemetic agents in a single, oral capsule may help simplify CINV management. Ongoing studies are evaluating new CINV approaches (eg, the novel NK1 receptor antagonist rolapitant), as well as the optimal use of existing therapies. Patient education regarding the timing, prevention, and treatment of CINV is another key component of CINV management.

    We investigated the efficacy of clonazepam as an antiemetic in cisplatin-based chemotherapy for lung cancer. Seven patients experienced cisplatin-induced vomiting despite antiemetic therapy including 5-hydroxytryptamine(3) (5-HT(3)) antagonist and dexamethasone. Therefore, the antiemetic therapy including clonazepam, 5-HT(3) antagonist and dexamethasone was subsequently explored in the next course for the same seven patients. We administered clonazepam (0.5 or 1.0 mg/kg) once a day orally for 5 d from day one prior to chemotherapy. The grade of delayed vomiting, evaluated according to Common Terminology Criteria for Adverse Events Version 3.0, in the courses of therapy with clonazepam was significantly lower than without clonazepam (p=0.013). The patients whose serum clonazepam concentrations were below the lower limit of detection (3.0 ng/ml) experienced vomiting in three of three courses, whereas the patients whose serum clonazepam concentrations were higher than 4.3 ng/ml experienced no vomiting in six of seven courses. We observed that the symptom of cisplatin-induced delayed vomiting is controlled with serum clonazepam levels in the order of 10.0 ng/ml.

    The purpose of this study was to investigate the antiemetic effect of the dopamine D 2 - and dopamine D 3 -receptor antagonist, amisulpride, in patients receiving cisplatin-based chemotherapy. This dose-finding, non-comparative study investigated the antiemetic effect and safety of increasing doses (2.5, 7.5 and 20 mg) of amisulpride against acute nausea and vomiting in the period 0-24 h after initiation of cisplatin-based chemotherapy. The 20 mg dose was also investigated in combination with the 5-HT 3 -receptor antagonist, ondansetron. The primary parameter was complete response (0-24 h), defined as no emesis and no need for rescue antiemetics. Secondary parameters were number of emetic episodes, severity of nausea and time to first emetic episode and start of nausea. A total of 51 patients were enrolled and evaluable. None of the 10 patients in the 2.5 and 7.5 mg groups obtained a CR. In the 20 mg monotherapy cohort, two of the 18 subjects (11%) had a CR, 3/18 (17%) had no emesis and 12/18 (67%) had no significant nausea. Seven subjects (39%) had no nausea at all (a VAS score cisplatin-induced acute nausea and vomiting. The effect against nausea is of particular interest. Randomised studies are warranted to further explore the effect and safety of amisulpride.

    This study compares the preoperative administration of ondansetron with that of droperidol or saline solution for the prevention of nausea and vomiting in otologic surgery patients. A total of 120 otherwise healthy individuals were randomly assigned to receive either saline solution, ondansetron (4 mg intravenously), or droperidol (25 microg/kg intravenously) before anesthetic induction. Intraoperative and postanesthesia care unit times were recorded along with incidence of nausea, vomiting, pain, nausea and recovery scores, and the administration of rescue antiemetics. Similar assessments were made during the next 24 hours. Demographics were similar, but more males received ondansetron. Anesthetic recovery scores were lower after administration of droperidol than after ondansetron. Incidence of nausea was similar between groups, but severity was greater with placebo and droperidol than with ondansetron. More vomiting occurred with placebo than with ondansetron or droperidol. No intergroup differences in rescue antiemetic administration were noted, however. Twenty-four hours later, more patients receiving placebo had nausea or vomited than patients receiving droperidol or ondansetron. Fewer women in the ondansetron group vomited than in the other two groups. Ondansetron 4 mg intravenously is as effective as droperidol and better than saline solution in preventing nausea and vomiting in patients undergoing otologic surgery. No cost advantage as determined by lower use of rescue antiemetics or shorter postanesthesia care unit times was noted after ondansetron therapy.

    Objective: The purpose of this study was to determine whether carbidopa (Lodosyn), an inhibitor of dopa-decarboxylase that blocks the synthesis of dopamine outside the brain, is an effective antiemetic in patients with familial dysautonomia (FD) and hyperdopaminergic nausea/retching/vomiting attacks. Methods: We enrolled 12 patients with FD in an open-label titration and treatment study to assess the safety of carbidopa. We then conducted a randomized, double-blind, placebo-controlled, crossover study to evaluate its antiemetic efficacy. Results: Previous fundoplication surgery in each patient studied prevented vomiting, but all of the subjects experienced severe cyclical nausea and uncontrollable retching that was refractory to standard treatments. Carbidopa at an average daily dose of 480 mg (range 325–600 mg/day) was well tolerated. In the double-blind phase, patients experienced significantly less nausea and retching while on carbidopa than on placebo (p < 0.03 and p < 0.02, respectively). Twenty-four-hour urinary dopamine excretion was significantly lower while on carbidopa (147 ± 32 µg/gCr) than while on placebo (222 ± 41µg/gCr, p < 0.05). Conclusions: Carbidopa is a safe and effective antiemetic in patients with FD, likely by reducing the formation of dopamine outside the brain. Classification of evidence: This study provides Class II evidence that carbidopa is effective in reducing nausea/retching/vomiting in patients with FD. PMID:23553478

    Intravenous droperidol has strong evidence for antiemetic efficacy in high risk patients for prevention of postoperative nausea and vomiting (PONV). However it is not clear whether continuous epidural administration of doroperidol prevent PONV. It has been reported that epidural adrenaline decreases PONV; therefore we prospectively compared the effectiveness of epidural droperidol and adrenaline for prophylaxis of PONV. Eighty-six patients were scheduled for abdominal gynecological surgery under general-epidural anesthesia in the study. Patients were randomly assigned to droperidol group or adrenaline group. We investigated the incidences of PONV, the frequency of using the antiemetics. There was no statistical difference between the groups. The incidences of PONV were 27.9% (doropeidol group) and 58.1% (adrenaline group), respectively (P = 0.0046). The frequency of the anti-emetics use were 18.6% and 41.9%, respectively (P = 0.0189). There was one patient who needed cancellation of continuous epidural administration for vomiting in adrenaline group, but no patient in doropeidol group. The results suggest that epidural droperidol effectively decreases PONV in high risk patients. However epidural adrenaline might be ineffective.

    To compare the recovery profile in terms of time of extubation, eye opening, orientation and mobility and frequency of Postoperative Nausea and Vomiting (PONV) between propofol and isoflurane based anesthesia in patients undergoing laparoscopic cholecystectomy with prophylactic antiemetic. After informed consent, a total of 60 ASA I-II patients scheduled for laparoscopic cholecystectomy were divided in two equal groups I and P. Anesthesia in all patients were induced by Nalbuphine 0.15 mg/kg, Midazolam 0.03 mg/kg, Propofol 1.5 mg/kg and Rocuronium 0.6 mg/kg. Anesthesia was maintained with Isoflurane in group I and propofol infusion in group P, while ventilation was maintained with 50% N/sub 2/O/sub 2/ mixture in both the groups. All patients were given antiemetic prophylaxis. Hemodynamics were recorded throughout anesthesia and recovery period. At the end of surgery, times of extubation, eye opening, orientation (by modified Aldrete score) and mobility (recovery profile) were assessed. PONV was observed and recorded immediately after extubation, during early postoperative period (0-4 hours) and late period (4-24 hours). Antiemetic requirements were also recorded for the same periods in both the groups. Propofol provided faster recovery (extubation and eye opening times) and orientation in immediate postoperative period with statistically significant differences between the groups (p<0.0001). Recovery characteristics were comparably lower in group I. More patients achieved full points (8) on modified Aldrete score at different time until 30 minutes in group P. Postoperative nausea and vomiting in early and late periods were significantly reduced in group P. Moreover, requirement of rescue antiemetic doses were significantly lower in group P in 24 hours (p<0.0001). In this series, recovery was much faster with earlier gain of orientation with propofol anesthesia compared to isoflurane in the early recovery periods. Propofol is likely to be a better choice of

    Full Text Available BACKGROUND: We carried out a systematic review and meta-analysis to evaluate the impact of prophylactic dexamethasone on post-operative nausea and vomiting (PONV, post-operative pain, and complications in patients undergoing thyroidectomy. METHODS: We searched Pubmed, Embase, and Cochrane Library databases for randomized controlled trials (RCTs that evaluated the prophylactic effect of dexamethasone versus placebo with or without other antiemetics for PONV in patients undergoing thyroidectomy. Meta-analyses were performed using RevMan 5.0 software. RESULTS: Thirteen RCTs that considered high quality evidence including 2,180 patients were analyzed. The meta-analysis demonstrated a significant decrease in the incidence of PONV (RR 0.52, 95% CI 0.43 to 0.63, P < 0.00001, the need for rescue anti-emetics (RR 0.42, 95% CI 0.30 to 0.57, P<0.00001, post-operative pain scores (WMD -1.17, 95% CI -1.91 to -0.44, P = 0.002, and the need for rescue analgesics (RR 0.65, 95% CI 0.50-0.83, P = 0.0008 in patients receiving dexamethasone compared to placebo, with or without concomitant antiemetics. Dexamethasone 8-10mg had a significantly greater effect for reducing the incidence of PONV than dexamethasone 1.25-5mg. Dexamethasone was as effective as other anti-emetics for reducing PONV (RR 1.25, 95% CI 0.86-1.81, P = 0.24. A significantly higher level of blood glucose during the immediate post-operative period in patients receiving dexamethasone compared to controls was the only adverse event. CONCLUSIONS: Prophylactic dexamethasone 8-10mg administered intravenously before induction of anesthesia should be recommended as a safe and effective strategy for reducing the incidence of PONV, the need for rescue anti-emetics, post-operative pain, and the need for rescue analgesia in thyroidectomy patients, except those that are pregnant, have diabetes mellitus, hyperglycemia, or contraindications for dexamethasone. More high quality trials are warranted to define the

    Some antiemetics are effective in the treatment of postoperative pain and shivering, as well as for postoperative nausea and vomiting (PONV). The aim of this study was to investigate the effects of ramosetron and dexamethasone on PONV, pain, and shivering and to determine the correlations between nausea, pain, and shivering. For this study, 123 patients scheduled for thyroid surgery were randomly allocated to one of three groups: the control group (group C, n = 41), dexamethasone group (group D, n = 41), or the ramosetron group (group R, n = 41). The patients were treated intravenously with 2 mL of 0.9 % NaCl, 2 mL of 5 mg/mL dexamethasone, or 2 mL of 0.15 mg/mL ramosetron immediately after anesthesia. The overall incidence and severity of postoperative nausea and the level of antiemetic consumption were significantly lower in group R compared with group D, and these parameters were significantly lower in groups R and D than in group C. There were significant differences in the incidence and severity of shivering, severity of pain, and analgesic consumption between group C and group R or D, but the incidence of shivering, pain severity, and analgesic consumption did not differ between groups R and D. The severity of shivering was significantly lower in group R than in group D. The correlation coefficients for shivering and pain, shivering and nausea, and pain and nausea were 0.210 (P = 0.010), 0.106 (P = 0.198), and 0.190 (P = 0.035), respectively, in group C. Two antiemetic drugs, ramosetron and dexamethasone, significantly reduced the incidence and severity of postoperative nausea and the need for administration of rescue antiemetic drugs. Furthermore, both drugs effectively decreased the severity of pain and shivering. Ramosetron was superior to dexamethasone for reducing nausea, antiemetic consumption, and the severity of nausea, but not for reducing the incidence of shivering. Further studies are required to elucidate the correlations between postoperative

    Purpose: A prospective observational multicenter trial was carried out to assess the incidence, pattern, and prognostic factors of radiation-induced emesis (RIE), and evaluate the use of antiemetic drugs in radiation oncology clinical practice. Methods and Materials: Fifty-one Italian radiation oncology centers took part in this trial. The accrual lasted 2 consecutive weeks, only patients starting radiotherapy in this period were enrolled. Exclusion criteria were age under 18 years, and concomitant chemotherapy. Evaluation was based on diary cards filled in daily by patients during radiotherapy and 1 week after stopping it. Diary cards recorded the intensity of nausea and any episode of vomiting and retching. Prophylactic and symptomatic antiemetic drug prescriptions were also registered. Results: Nine hundred thirty-four patients entered the trial, and 914 were evaluable. Irradiated sites were: breast in 211 patients, pelvis in 210 patients, head and neck in 136 patients, thorax in 129 patients, brain in 52 patients, upper abdomen in 42 patients, skin and/or extremities in 37 patients, and other sites in 97 patients. Vomiting and nausea occurred in 17.1% and 37.3% of patients, respectively, and 38.7% patients had both vomiting and nausea. At multifactorial analysis, the only patient-related risk factor that was statistically significant was represented by previous experience with cancer chemotherapy. Moreover, two radiotherapy (RT)-related factors were significant risk factors for RIE, the irradiated site and field size. In fact, a statistically significant higher percentage of RIE was registered in upper abdomen RT and RT fields > 400 cm 2 . Although nonstatistically significant, patients receiving RT to the thorax and head and neck presented a higher incidence of RIE. Only a minority (14%) of patients receiving RT were given an antiemetic drug, and the prescriptions were more often symptomatic than prophylactic (9% vs. 5%, respectively). Different compounds and

    Full Text Available Background: The incidence of post-operative nausea and vomitting (PONV is increased after middle ear surgery and it may complicate and interact with reconstruction after surgery, so prevention and treatment of these complications are necessary.The aim of this study was to evaluate the efficacy of anti-emetic combinations in decreasing the PONV after middle ear surgery.Materials and methods: This double blind clinical trial was carried out during 2007-2008 on 111 patients of 15-45 years old with ASA I-II who were candidates for elective middle ear surgery under general anesthesia. The patients were divided into three groups. Patients in the ON group received Ondansetrone 0.1mg/kg + Nacl 0.9% 2cc, OD group received Ondansetrone 0.1mg/kg + Dexamethasone 0.15mg/kg and MD group received Dexamethasone 0.15mg/kg+ Metoclopramide 0.15mg/kg intravenously just before the end of surgery. The patients were evaluated for nausea, vomiting, need of anti-emetic drugs and drug dosage in recovery, 1-6, 6-12 and 12-24 hours after operation and then all data were statistically analyzed by SPSS software, Chi-square, ANOVA and t- Test. P<0.05 was significant.Results: There were no significant differences among three groups in age and sex. The incidence of PONV among 3 groups was not significantly different during 24 hours after operation. (P=0.271 but the incidence of PONV in the first six hours was different among 3 groups (P=0.007 (ON: 8.1%, OD: 0%, MD: 21.6%. Also Metoclopramide consumption was significant between three groups. Conclusion: This study showed that the need to anti-emetic drugs in first 6 hours was the least in OD group, but the difference in the incidence of PONV was not significant otherwise.

    Postoperative nausea and vomiting (PONV) is the most common postoperative complication. The postoperative use of opioids is known to increase the incidence. We compared fosaprepitant, a neurokinin-1 (NK1) receptor antagonist, and ondansetron for their preventive effects on PONV in patients who underwent gynecologic abdominal surgery with patient-controlled epidural analgesia. This prospective, double-blind, randomized study comprised 44 patients who underwent gynecologic abdominal surgery. They were randomly allocated to receive 150 mg intravenous fosaprepitant (n = 24; NKI group) or 4 mg ondansetron (n = 20; ONS group) before anesthesia, which was maintained with volatile anesthetics, remifentanil, fentanyl, and rocuronium. All patients received postoperative fentanyl by patient-controlled epidural anesthesia. The incidence of nausea and vomiting, complete response rate (i.e., no vomiting and no rescue antiemetic use), rescue antiemetic use, nausea score (0-3), and visual analog scale score (VAS 0-10) for pain were recorded at 2, 24, 48, and 72 h after surgery. No (0 %) patient in the NKI group experienced vomiting after surgery; however, 4-6 (20-30 %) of 20 patients in the ONS group experienced vomiting. This difference was significant at 0-24, 0-48, and 0-72 h. During the study period, no significant differences existed between the NK1 and ONS groups in the incidence of PONV, complete response rate, rescue antiemetic use, nausea score, and VAS score for pain. Compared to ondansetron, fosaprepitant more effectively decreased the incidence of vomiting in patients who underwent gynecologic abdominal surgery with patient-controlled epidural analgesia.

    The introduction of second generation serotonin 5-HT 3 receptor (5-HT 3 ) antagonist palonosetron combined with long-acting substance P neurokinin NK 1 receptor (NK 1 ) antagonists (e.g. netupitant) has substantially improved antiemetic therapy against early- and delayed-phases of emesis caused by highly emetogenic chemotherapeutics such as cisplatin. However, the improved efficacy comes at a cost that many patients cannot afford. We introduce a new class of antiemetic, the antiasthmatic leukotriene CysLT1 receptor antagonist pranlukast for the suppression of cisplatin-evoked vomiting. Pranlukast (10mg/kg) by itself significantly reduced the mean frequency of vomits (70%) and fully protected least shrews from vomiting (46%) during the delayed-phase of cisplatin (10mg/kg)-evoked vomiting. Although, pranlukast tended to substantially reduce both the mean frequency of vomits and the number of shrews vomiting during the early-phase, these reductions failed to attain significance. When combined with a first (tropisetron)- or a second (palonosetron)-generation 5-HT 3 receptor antagonist, pranlukast potentiated their antiemetic efficacy during both phases of vomiting. In addition, pranlukast by itself prevented several intracellular signal markers of cisplatin-evoked delayed-vomiting such as phosphorylation of ERK1/2 and PKA. When pranlukast was combined with either palonosetron or tropisetron, these combinations suppressed the evoked phosphorylation of: i) ERK1/2 during both acute- and delayed-phase, ii) PKCα/β at the peak acute-phase, and iii) PKA at the peak delayed-phase. The current and our published findings suggest that overall behavioral and intracellular signaling effects of pranlukast via blockade of CysLT1 receptors generally appear to be similar to the NK 1 receptor antagonist netupitant with some differences.

    Full Text Available Vito Lorusso National Cancer Research Centre, Istituto Tumori Giovanni Paolo II, Bari, Italy Abstract: As recommended by most recent antiemetic guidelines, the optimal prophylaxis of chemotherapy-induced nausea and vomiting (CINV requires the combination of 5-HT3 receptor antagonist (RA with an NK1-RA. Moreover, the major predictors of acute and delayed CINV include: young age, female sex, platinum- or anthracycline-based chemotherapy, nondrinker status, emesis in the earlier cycles of chemotherapy, and previous history of motion/morning sickness. Despite improved knowledge of the pathophysiology of CINV and advances in the availability of active antiemetics, an inconsistent compliance with their use has been reported, thereby resulting in suboptimal control of CINV in several cases. In this scenario, a new antiemetic drug is now available, which seems to be able to guarantee better prophylaxis of CINV and improvement of adherence to guidelines. In fact, netupitant/palonosetron (NEPA is a ready-to-use single oral capsule, combining an NK1-RA (netupitant and a 5-HT3-RA (palonosetron, which is to be taken 1 hour before the administration of chemotherapy, ensuring the coverage from CINV for 5 days. We reviewed the role of NEPA in patients at high risk of CINV receiving highly emetogenic chemotherapy. In these patients, NEPA plus dexamethasone, as compared to standard treatments, achieved superior efficacy in all primary and secondary end points during the acute, delayed, and overall phases, including nausea assessment. Moreover, these results were also achieved in female patients receiving anthracycline plus cyclophosphamide-based chemotherapy. NEPA represents a real step forward in the prophylaxis of CINV.

    Full Text Available Cannabis sativa (CS, family Cannabinaceae has been reported for its anti-emetic activity against cancer chemotherapy-induced emesis in animal models and in clinics. The current study was designed to investigate CS for potential effectiveness to attenuate cisplatin-induced vomiting in healthy pigeons and to study the impact on neurotransmitters involved centrally and peripherally in the act of vomiting. High-performance liquid chromatography system coupled with electrochemical detector was used for the quantification of neurotransmitters 5-hydroxytryptamine (5HT, dopamine (DA and their metabolites; Di-hydroxy Phenyl Acetic acid (Dopac, Homovanillic acid (HVA, and 5-hydroxy indole acetic acid (5HIAA centrally in specific brain areas (area postrema and brain stem while, peripherally in small intestine. Cisplatin (7 mg/kg i.v. induce emesis without lethality across the 24 h observation period. CS hexane fraction (CS-HexFr; 10 mg/kg attenuated cisplatin-induced emesis ∼ 65.85% (P < 0.05; the reference anti-emetic drug, metoclopramide (MCP; 30 mg/kg, produced ∼43.90% reduction (P < 0.05. At acute time point (3rd h, CS-HexFr decreased (P < 0.001 the concentration of 5HT and 5HIAA in the area postrema, brain stem and intestine, while at 18th h (delayed time point CS-HexFr attenuated (P < 0.001 the upsurge of 5HT caused by cisplatin in the brain stem and intestine and dopamine in the area postrema. CS-HexFr treatment alone did not alter the basal neurotransmitters and their metabolites in the brain areas and intestine except 5HIAA and HVA, which were decreased significantly. In conclusion the anti-emetic effect of CS-HexFr is mediated by anti-serotonergic and anti-dopaminergic components in a blended manner at the two different time points, i.e., 3rd and 18th h in pigeons.

    Full Text Available Abstract Background Successful breastfeeding is a goal set forth by the World Health Organization to improve neonatal care. Increasingly, patients express the desire to breastfeed, and clinicians should facilitate successful breastfeeding. The primary aim of this study is to determine if postoperative nausea and vomiting (PONV or postoperative pain are associated with decreased breastfeeding success after cesarean delivery. Methods This is a historical cohort study using the Stony Brook Elective Cesarean Delivery Database. Self-reported breastfeeding success at 4 weeks postoperative was analyzed for associations with postoperative antiemetic use and postoperative pain scores. Breastfeeding success was also analyzed for associations with patient factors and anesthetic medications. Results Overall, 86% of patients (n = 81 who intended on breastfeeding reported breastfeeding success. Breastfeeding success was not associated with postoperative nausea or vomiting as measured by post anesthesia care unit antiemetic use (15% use in successful vs. 18% use in unsuccessful, p = 0.67 or 48-h antiemetic use (28% use in successful group vs 36% use in unsuccessful group, p = 0.732. Pain visual analog scale scores at 6, 12 and 24 h postoperatively were not significantly different between patients with or without breastfeeding success. Breastfeeding success was associated with having had at least 1 previous child (86% vs 36%, p < 0.001. Patients with asthma were less likely to have breastfeeding success (45% vs 4%, p = 0.002. Conclusions Efforts to improve PONV and pain after cesarean delivery may not be effective in improving breastfeeding success. To possibly improve breastfeeding rates, resources should be directed toward patients with no previous children and patients with asthma.

    Chemotherapy-induced nausea (CIN) has a significant negative impact on the quality of life of cancer patients. The use of 5-hydroxytryptamine-3 (5-HT 3 ) receptor antagonists (RAs) has reduced the risk of vomiting, but (except for palonosetron) their effect on nausea, especially delayed nausea, is limited. This article reviews the role of NK 1 RAs when combined with 5-HT 3 RA-dexamethasone in CIN prophylaxis. Aprepitant has not shown consistent superiority over a two-drug (ondansetron-dexamethasone) combination in nausea control after cisplatin- or anthracycline-cyclophosphamide (AC)-based highly emetogenic chemotherapy (HEC). Recently, dexamethasone and dexamethasone-metoclopramide were demonstrated to be non-inferior to aprepitant and aprepitant-dexamethasone, respectively, for the control of delayed nausea after HEC (AC/cisplatin), and are now recognized in the guidelines. The potential impact of the new NK 1 RAs rolapitant and netupitant (oral fixed combination with palonosetron, as NEPA) in CIN prophylaxis is discussed. While the clinical significance of the effect on nausea of the rolapitant-granisetron-dexamethasone combination after cisplatin is not conclusive, rolapitant addition showed no improvement in nausea prophylaxis after AC or moderately emetogenic chemotherapy (MEC). NEPA was superior to palonosetron in the control of nausea after HEC (AC/cisplatin). Moreover, the efficacy of NEPA in nausea control was maintained over multiple cycles of HEC/MEC. Recently, NK 1 RAs have been challenged by olanzapine, with olanzapine showing superior efficacy in nausea prevention after HEC. Fixed antiemetic combinations (such as NEPA) or new antiemetics with a long half-life that may be given once per chemotherapy cycle (rolapitant or NEPA) may improve patient compliance with antiemetic treatment.

    Antiemetic guideline recommendations are inconsistent as to whether a neurokinin-1 receptor antagonist (NK1 RA) should be administered with a 5-hydroxytryptamine-3 (5HT3) RA + dexamethasone (DEX) in patients receiving carboplatin. Patients receiving cisplatin routinely receive an NK1 RA-containing regimen with a resulting 14-22 % benefit in no emesis rates over a 5-HT3 RA/DEX control. Recent studies suggest a similar benefit in patients receiving carboplatin. NEPA is the first fixed antiemetic combination agent and comprises the highly selective NK1 RA, netupitant, and pharmacologically distinct 5-HT3 RA, palonosetron (PALO). This paper presents the efficacy of NEPA in the subset of patients receiving carboplatin in a phase 3 trial (NCT01376297), in the context of aprepitant (APR) data in the carboplatin setting. One hundred ninety-six patients (47 % of all study patients: n = 145 NEPA + DEX; n = 51 APR + PALO + DEX) received carboplatin in a multinational, double-blind, randomized phase 3 study. Complete response (CR: no emesis/rescue) and no significant nausea (NSN: score ≤25 on 100 mm visual analog scale) rates were calculated. Cycle 1-4 overall (0-120 h) CR rates were similar for NEPA (80, 91, 92, and 93 %) and APR (82, 88, 88, and 90 %). Overall NSN rates were also similar (NEPA 84-96 %; APR 82-90 %). Response rates for NEPA and APR regimens were similar and consistent with prior studies evaluating the contribution of adding NK1 RAs in patients receiving carboplatin. Considering such evidence, guideline groups/practitioners should consider giving a NK1 RA antiemetic triplet in patients receiving carboplatin.

    Nausea and vomiting are major adverse effects of chemotherapy and can greatly impact patients' quality of life. Although chemotherapy-induced nausea and vomiting (CINV) prevalence is high, treatment remains difficult. Palonosetron is a 5-hydroxytryptamine receptor antagonist (5-HT3RA) approved for treatment of CINV. The purpose of this review is to discuss existing and emerging therapeutic options, and examine studies focusing on palonosetron with regards to efficacy, pharmacology, tolerability, safety, and patient-derived outcomes. A literature search was conducted using Ovid MEDLINE and EMBASE to identify relevant studies using palonosetron alone or in combination with other antiemetics. Studies were extracted if they included complete response (CR), complete control (CC), no nausea, no vomiting, and no rescue medications as an endpoint. Studies were also included if safety endpoints were examined. Palonosetron alone has been shown to improve CR and CC rates for patients receiving low, moderate, or high emetogenic chemotherapy. Rates were further improved with the addition of dexamethasone, a corticosteroid. Furthermore, the addition of neurokinin-1 receptor antagonists, such as netupitant markedly improved efficacy profiles compared to palonosetron alone. Aprepitant is an antiemetic that has exhibited positive results in combination with palonosetron. Recently, a new drug consisting of netupitant and palonosetron (NEPA) has demonstrated significantly more efficacious prevention of CINV. Regardless of the combination, palonosetron has been well tolerated. The most common adverse events were constipation, headache, fatigue, and dizziness, with the majority of patients describing them as only mild or moderate. Palonosetron, alone or with other antiemetics, has improved CINV treatment due to its ability to significantly reduce delayed phases of CINV, compared to similar 5-HT3RAs. Palonosetron is both more effective than first generation 5-HT3RAs and safer, as it

Moreover, these results were also achieved in female patients receiving anthracycline plus cyclophosphamide-based chemotherapy. NEPA represents a real step forward in the prophylaxis of CINV.

    Chemotherapy-induced nausea and vomiting (CINV) places a significant burden on the patient. Herbal agents are the most commonly complementary therapies used among the public. This study was done to determine the effect of ginger and chamomile capsules on nausea and vomiting in cases undergoing chemotherapy for breast cancer (BC). In a randomized, double-blind and clinical trial study, 65 women with BC undergoing chemotherapy were referred to Breast Cancer Research Center, Tehran, Iran, between May 2013 to June 2014. Regimen for ginger group for 5 days before and 5 days after chemotherapy was: 2 times a day and 500 mg capsules of powdered ginger root in addition to a routine antiemetic regimen consisting of dexamethasone, metoclopramide and aprepitant (DMA) capsules. Chamomile group similarly was: 2 times a day and 500 mg capsules of Matricaria chamomilla extract in addition to a routine antiemetic regimen consisting of DMA capsules. Control group, routine antiemetic regimen consisting of DMA capsules. There were no significant differences between the ginger, chamomile and control groups regarding age. Drugs used for chemotherapy were identical and duration of disease was also matched (1-4 months). Ginger and chamomile were both significantly effective for reducing the frequency of vomiting, there being no significant difference between the ginger and chamomile groups. Moreover, unlike the chamomile, ginger significantly influenced the frequency of nausea. According to the findings of this study, it should be declared that taking ginger capsules (1 g/day) might relieve CINV safely. Nurses dealing directly with cancer patients should be responsible for providing educational programs for patients and their families about how to deal with their drug regimens and associated side effects.

    Full Text Available Background and Aims: Post-operative nausea and vomiting (PONV is highly distressing and unpleasant symptom. Dexamethasone and palonosetron are effective antiemetics with minimal side effect profile. This study compares the efficacy of palonosetron or dexamethasone alone and their combination (palonosetron plus dexamethasone for prevention of PONV after laparoscopic cholecystectomy. Methods: This prospective, randomised, double-blind trial was done on 187 adults, American Society of Anesthesiologists Grade I and II patients, aged 18–75 years undergoing laparoscopic cholecystectomy. They were allocated to three groups which were to receive either of the three treatment regimens: dexamethasone 8 mg (Group D, n = 57, palonosetron 0.075 mg (Group P, n = 66 or dexamethasone 8 mg plus palonosetron 0.075 mg (Group PD, n = 64. The primary outcome was incidence of PONV in 24 h and the secondary outcome was a number of rescue antiemetic required. One-way ANOVA test was used to compare the means amongst three groups. To compare the proportions in the groups, Chi-square test/Fisher's exact test/Two proportions Z-test was applied as appropriate. Results: Overall incidences of PONV in the study 24 h postoperatively were 23.4% in PD, 27.2% in P group and 56.14% in D group (P < 0.001. Requirement of rescue antiemetic was more in dexamethasone group than other two groups (PD = 1 time, P = 1.38 times and D = 1.5 times. Conclusion: Palonosetron alone and palonosetron-dexamethasone combination were equally effective in the prevention of PONV. Dexamethasone alone was least effective amongst the three groups. There is no difference between palonosetron and palonosetron-dexamethasone for PONV prevention.

    Purpose: To investigate international patterns of practice in the management of radiation therapy-induced nausea and vomiting (RINV). Methods and Materials: Oncologists prescribing radiation therapy in the United States, Canada, The Netherlands, Australia, New Zealand, Spain, Italy, France, Hong Kong, Singapore, Cyprus, and Israel completed a Web-based survey that was based on 6 radiation therapy-only clinical cases modeled after the minimal-, low-, moderate-, and high-emetic risk levels defined in the antiemetic guidelines of the American Society of Clinical Oncology and the Multinational Association of Supportive Care in Cancer. For each case, respondents estimated the risks of nausea and vomiting separately and committed to an initial management approach. Results: In total, 1022 responses were received. Risk estimates and management decisions for the minimal- and high-risk cases varied little and were in line with guideline standards, whereas those for the low- and moderate-risk cases varied greatly. The most common initial management strategies were as follows: rescue therapy for a minimal-risk case (63% of respondents), 2 low-risk cases (56% and 80%), and 1 moderate-risk case (66%); and prophylactic therapy for a second moderate-risk case (75%) and a high-risk case (95%). The serotonin (5-HT){sub 3} receptor antagonists were the most commonly recommended prophylactic agents. On multivariate analysis, factors predictive of a decision for prophylactic or rescue therapy were risk estimates of nausea and vomiting, awareness of the American Society of Clinical Oncology antiemetic guideline, and European Society for Therapeutic Radiology and Oncology membership. Conclusions: Risk estimates and management strategies for RINV varied, especially for low- and moderate-risk radiation therapy cases. Radiation therapy-induced nausea and vomiting are under-studied treatment sequelae. New observational and translational studies are needed to allow for individual patient risk

    Hypotension is common after spinal anesthesia for Cesarean delivery. It is associated with nausea, vomiting, and fetal acidosis. Previous research on phenylephrine excluded obese subjects. We compared the incidence of intraoperative nausea and vomiting (IONV) in obese patients who received a prophylactic phenylephrine infusion vs those who received bolus dosing for the treatment of spinal-induced hypotension. In this multicentre, double-blinded randomized controlled trial, 160 obese women undergoing elective Cesarean delivery under spinal anesthesia were randomized to receive a prophylactic phenylephrine infusion initiated at 50 μg·min -1 (and titrated according to a predefined algorithm) or 100 μg phenylephrine boluses to treat hypotension. Maternal systolic blood pressure was maintained within 20% of baseline. The primary study outcome was the incidence of IONV. Intraoperative nausea and vomiting were significantly reduced in the infusion group compared to the bolus group (46% vs 75%, respectively; relative risk [RR], 0.61; 95% confidence interval [CI], 0.47 to 0.80; P < 0.001). This was associated with significantly reduced need for intraoperative rescue antiemetics (26% vs 42%, respectively; RR, 0.62; 95% CI, 0.40 to 0.97; P = 0.04), but no difference in the incidence of vomiting. Postoperative vomiting at two hours was reduced in the infusion group (11% vs 25%; RR, 0.44; 95% CI, 0.21 to 0.90; P = 0.02);however, there were no differences in the incidence or severity of postoperative nausea, need for rescue antiemetics at two hours and 24 hr, or the incidence of postoperative vomiting at 24 hr. In obese women undergoing Cesarean delivery with spinal anesthesia, prophylactic phenylephrine infusion was associated with less intraoperative nausea, less need for rescue antiemetics, and reduced early postoperative vomiting. www.clinicaltrials.gov (NCT01481740).

    To compare the prophylactic administration of ondansetron with droperidol or placebo to determine its effectiveness in reducing postoperative nausea and vomiting after middle ear procedures. Prospective, randomized, double-blind study. Inpatient otolaryngology service at a university medical center. 120 ASA physical status I and II patients presenting for elective middle ear surgical procedures. Patients were randomly assigned to receive either placebo (Group 1), ondansetron 4 mg intravenously (IV) (Group 2), or droperidol 25 mcg/kg i.v. (Group 3) 10 minutes before induction of general anesthesia using thiopental 5 mg/kg i.v. with fentanyl 2 mcg/kg i.v. and maintenance anesthesia with isoflurane 1% to 2% end-tidal in a 50% air/oxygen mixture. Total surgical, anesthesia, extubation, and postanesthesia care unit (PACU) occupancy times were recorded along with anesthesia recovery scores. The incidence and severity of nausea, vomiting, and pain along with rescue antiemetic administration, also were recorded. Similar assessments were made over the next 24 hours. Intergroup demographic data were similar except that the male to female ratio was higher in the ondansetron group. Stewart scores, reflecting emergence from anesthesia, were higher with ondansetron compared with droperidol. The incidence of nausea was similar between the groups but the severity was less after ondansetron therapy. More patients vomited after placebo than when given either droperidol or ondansetron. No intergroup differences were noted in the use of rescue antiemetics. Twenty-four hours later, more patients who received the placebo drug had nausea or vomited compared with either ondansetron or droperidol. Ondansetron 4 mg i.v. is as effective as droperidol and better than placebo in preventing nausea and vomiting in patients undergoing middle ear surgery. No cost advantage as determined by lower use of rescue antiemetics or shorter PACU times was noted after the prophylactic administration of

    To determine the frequency of postoperative vomiting (POV) in children submitted to outpatient surgery and to compare the efficacy of antiemetic drugs in preventing this complication. Nausea and vomiting are common in the immediate postoperative period following anesthetic and surgical procedures. Compared to adults, pediatric patients are more likely to develop postoperative nausea and vomiting, the incidence of which ranges from 8.9% to 42%. This double-blind, randomized, placebo-controlled clinical trial included 129 children. The participants were randomized into three prophylactic treatment groups: dexamethasone (n = 43), ondansetron in combination with dexamethasone (n = 44), and placebo (n = 42). The variables studied were the frequency of POV and the incidence of vomiting after the patient had been discharged from hospital, the need for antiemetic rescue therapy in the postanesthesia care unit (PACU), need for hospitalization, and the time the patient remained in the PACU. A significance level of 5% was adopted. Postoperative vomiting occurred in 12.4% of the children, with no statistically significant difference between the groups: 6.8% in the group receiving ondansetron combined with dexamethasone, 14.3% in the placebo group, and 14% in the group that received dexamethasone alone (P = 0.47). Furthermore, no significant difference was found between the groups with respect to the time the children remained in the PACU, and only five patients reported having vomited following discharge from hospital. The prophylactic use of antiemetic drugs failed to reduce the incidence of POV in pediatric outpatient surgery with a low emetic potential; therefore, routine prophylaxis may be unnecessary. © 2012 Blackwell Publishing Ltd.

    Pharmacological therapy is only partially effective in preventing or treating chemotherapy induced nausea and vomiting (CINV). Therefore, exploring the complementary role of non-pharmacological approaches used in addition to pharmacological agents is important. Nevasic uses specially constructed audio signals hypothesized to generate an antiemetic reaction. The aim of this study was to examine the feasibility of conducting a randomized controlled trial (RCT) to evaluate the effectiveness of Nevasic to control CINV. A mixed methods design incorporating an RCT and focus group interviews. For the RCT, female breast cancer patients were randomized to receive either Nevasic plus usual care, music plus usual care, or usual care only. Data were analysed using descriptive statistics and linear mixed-effects models. Five focus group interviews were conducted to obtain participants' views regarding the acceptability of the interventions in the trial. 99 participants were recruited to the RCT and 15 participated in focus group interviews. Recruitment targets were achieved. Issues of Nevasic acceptability were highlighted as weaknesses of the program. This study did not detect any evidence for the effectiveness of Nevasic; however, the results showed statistically significant less use of anti-emetics (p = 0.003) and borderline non-significant improvement in quality of life (p = 0.06). Conducting a non-pharmacological intervention using such an audio program is feasible, although difficulties and limitations exist with its use. Further studies are required to investigate the effectiveness of Nevasic from perspectives such as anti-emetic use, as well as its overall effect on the levels of nausea and vomiting.

    Full Text Available AIMS AND OBJECTIVE: This prospective double blind randomized study was conducted to compare: 1. The efficacy and safety of prophylactic administration of Metoclopramide versus Ondansetron in the control of postoperative nausea and vomiting in patients receiving intravenous Tr amadol as postoperative analgesic. 2. To study the incidence of post operative nausea and vomiting with IV bolus Tramadol. METHODS: 90 patients ASA grade I and II, age 18 - 60 years, posted for hernia, hydrocele and other peripheral lower limb surgeries under subarachnoid block were selected . Patients were randomly allocated into three groups of thirty each. All surgeries were performed under subarachnoid block and received IV Tramadol 100 m g 8 hourly for 24 hours as post - operative analgesic. Group N received no prophylactic antiemetic. Group M received 10 mg Metoclopramide 12 hourly. Group O received 4 mg Ondansetron 12 hourly. Vital signs, nausea, vomiting, pain, sedation, need for rescue a ntiemetic, rescue analgesic and adverse effects were recorded for 24 hours. RESULTS: Ondansetron group (Group O significantly reduced the incidence of PONV as compared to Metoclopramide (Group M and no antiemetic group (Group N .But Metoclopramide was fo und to be not significantly effective in controlling PONV in patients receiving Tramadol as analgesic. None of the patients in Group O required rescue antiemetic as compared to 13.3% patients in Group M and 26.7% patients in Group N. There was statisticall y no significant difference between the 3 groups with respect to requirement of rescue analgesic. No major adverse effects were observed which can be attributed to either Metoclopramide or Ondansetron. CONCLUSION: Ondansetron was more effective than Metoclopramide in controlling PONV, in patients receiving IV Tramadol as post-operative analgesia

Research in this area is plentiful and has focused on event prediction and pharmacological prophylaxis but despite this, postoperative nausea and vomiting (PONV typically occurs in 20%–30% of patients in contemporary practice. Prediction of postoperative and postdischarge nausea and vomiting is particularly important in the ambulatory surgical population as these symptoms may occur following discharge from hospital and continue for up to one week when access to antiemetic therapies is limited. Many of the existing predictive scoring systems are based on data from inpatient populations and limited to the first 24 hours after surgery. Scoring systems based on data from ambulatory surgical populations to predict PONV are only moderately good. The best-performing systems in ambulatory patients are those of Sinclair and Sarin with an area under the receiver operating characteristic curve of 0.78 and 0.74, respectively, but are limited by the short duration of follow-up and a greater emphasis on nausea than vomiting. Given that the ability to predict both PONV and postdischarge nausea and vomiting is clearly limited, emphasis has been placed on prophylactic strategies that incorporate antiemetic medication, intravenous hydration, and nonnarcotic analgesia. PONV has been reduced to <10% in institutions using multimodal approaches. Scoring systems may facilitate “risk tailoring” in which patient risk profile is used as a stratification method for pharmacointervention.

  9. Delta-9-tetrahydrocannabinol differentially suppresses cisplatin-induced emesis and indices of motor function via cannabinoid CB(1) receptors in the least shrew.

    We have recently shown that the cannabinoid CB(1) receptor antagonist, SR 141716A, produces emesis in the least shrew (Cryptotis parva) in a dose- and route-dependent manner. This effect was blocked by delta-9-tetrahydrocannabinol (Delta(9)-THC). The present study investigates the cannabinoid receptor mechanisms by which Delta(9)-THC produces its antiemetic effects against cisplatin (20 mg/kg, i.p.)-induced emesis as well as its cannabimimetic activity profile (motor reduction) in the least shrew. Intraperitoneal administration of Delta(9)-THC (1, 2.5, 5 and 10 mg/kg) dose-dependently reduced both the percentage of animals vomiting (ID(50)=1.8+/-1.6 mg/kg) and the frequency of vomits (ID(50)=0.36+/-1.18 mg/kg) in a potent manner. The lowest significantly effective antiemetic dose of Delta(9)-THC for the latter emesis parameters was 2.5 mg/kg. Although Delta(9)-THC reduced the frequency of vomits up to 98%, it failed to completely protect all tested shrews from vomiting (80% protection). The cannabinoid CB(1) antagonist (SR 141716A) and not the CB(2) antagonist (SR 144528), reversed the antiemetic effects of Delta(9)-THC in a dose-dependent fashion. Delta(9)-THC (1, 5, 10 and 20 mg/kg, ip) suppressed locomotor parameters (spontaneous locomotor activity, duration of movement and rearing frequency) in a biphasic manner and only the 20-mg/kg dose simultaneously suppressed the triad of locomotor parameters to a significant degree. Subcutaneous (1-10 mg/kg) and intraperitoneal (0.05-40 mg/kg) injection of some doses of SR 141716A caused significant reductions in one or more components of the triad of locomotor parameters but these reductions were not dose dependent. Subcutaneous injection of SR 141716A (0.2, 1, 5 and 10 mg/kg) reversed the motor suppressant effects of a 20-mg/kg dose of Delta(9)-THC (ip) in a dose-dependent manner. Relative to its motor suppressant effects, Delta(9)-THC is a more potent antiemetic agent. Both effects are probably mediated via CB(1

    Radiotherapy-induced emesis depends on the site of irradiation, the field size and the dose per fraction and is generally less intense than chemotherapy-induced emesis. Established anti-emetic drugs offer only limited symptom control (50%). Ondansetron, a 5HT[sub 3] receptors antagonist, had proven a complete or a major control efficacy (0-2 emetic episodes) of 68 to 95% in three pilot studies (fractionated, single-dose and total body irradiations). In controlled studies, ondansetron efficacy was significantly higher than placebo, metoclopramide and prochlorperazine. The treatment was well tolerated in the different studies.

    Purpose: To systematically review the effectiveness and safety of 5-hydroxytryptamine-3 receptor antagonists (5-HT3 RAs) compared with other antiemetic medication or placebo for prophylaxis of radiation-induced nausea and vomiting. Methods and Materials: We searched the following electronic databases: MEDLINE, Embase, the Cochrane Central Register of Controlled Clinical Trials, and Web of Science. We also hand-searched reference lists of included studies. Randomized, controlled trials that compared a 5-HT3 RA with another antiemetic medication or placebo for preventing radiation-induced nausea and vomiting were included. We excluded studies recruiting patients receiving concomitant chemotherapy. When appropriate, meta-analysis was conducted using Review Manager (v5) software. Relative risks were calculated using inverse variance as the statistical method under a random-effects model. We assessed the quality of evidence by outcome using the Grading of Recommendations Assessment, Development, and Evaluation approach. Results: Eligibility screening of 47 articles resulted in 9 included in the review. The overall methodologic quality was moderate. Meta-analysis of 5-HT3 RAs vs. placebo showed significant benefit for 5-HT3 RAs (relative risk [RR] 0.70; 95% confidence interval [CI] 0.57-0.86 for emesis; RR 0.84, 95% CI 0.73-0.96 for nausea). Meta-analysis comparing 5-HT3 RAs vs. metoclopramide showed a significant benefit of the 5-HT3 RAs for emetic control (RR 0.27, 95% CI 0.15-0.47). Conclusion: 5-Hydroxytryptamine-3 RAs are superior to placebo and other antiemetics for prevention of emesis, but little benefit was identified for nausea prevention. 5-Hydroxytryptamine-3 RAs are suggested for prevention of emesis. Limited evidence was found regarding delayed emesis, adverse events, quality of life, or need for rescue medication. Future randomized, controlled trials should evaluate different 5-HT3 antiemetics and new agents with novel mechanisms of action such at the NK

    NMDA receptor antagonists include the prescription medication ketamine, the illicit xenobiotics PCP, MXE, and other novel PCP analogs, and the OTC medication DXM. The NMDA receptor antagonist most commonly abused by adolescents in the United States is DXM. These xenobiotics cause dissociative effects by non-competitively inhibiting the action of glutamate at the NMDA receptor. Additionally, these agents modulate the actions of monoamine neurotransmitters, agonize opioid receptors, and inhibit nitric oxide synthase. Patients typically present with sympathomimetic and neuropsychiatric clinical manifestations after abuse of NMDA receptor antagonists. Treatment is generally symptomatic and supportive. Interventions include benzodiazepines, propofol, fluids, antiemetics, aggressive cooling, and respiratory support.

    Cisplatin-like chemotherapeutics cause vomiting via calcium (Ca 2+ )-dependent release of multiple neurotransmitters (dopamine, serotonin, substance P, etc.) from the gastrointestinal enterochromaffin cells and/or the brainstem. Intracellular Ca 2+ signaling is triggered by activation of diverse emetic receptors (including tachykininergic NK 1 , serotonergic 5-HT 3 , dopaminergic D 2 , cholinergic M 1 , or histaminergic H 1 ) , whose activation in vomit-competent species can evoke emesis. Other emetogens such as cisplatin, rotavirus NSP4 protein and bacterial toxins can also induce intracellular Ca 2+ elevation. Netupitant is a highly selective neurokinin NK 1 receptor (NK 1 R) antagonist and palonosetron is a selective second-generation serotonin 5-HT 3 receptor (5-HT 3 R) antagonist with a distinct pharmacological profile. An oral fixed combination of netupitant/palonosetron (NEPA; Akynzeo(®)) with >85% antiemetic efficacy is available for use in the prevention of acute and delayed chemotherapy-induced nausea and vomiting (CINV). Cannabinoid CB 1 receptor agonists possess broad-spectrum antiemetic activity since they prevent vomiting caused by a variety of emetic stimuli including the chemotherapeutic agent cisplatin, 5-HT 3 R agonists, and D 2 R agonists. Our findings demonstrate that application of the L-type Ca 2+ channel (LTCC) agonist FPL 64176 and the intracellular Ca 2+ mobilizing agent thapsigargin (a sarco/endoplasmic reticulum Ca 2+ -ATPase inhibitor) cause vomiting in the least shrew. On the other hand, blockade of LTCCs by corresponding antagonists (nifedipine or amlodipine) not only provide broad-spectrum antiemetic efficacy against diverse agents that specifically activate emetogenic receptors such as 5-HT 3 , NK 1 , D 2 , and M 1 receptors, but can also potentiate the antiemetic efficacy of palonosetron against the non-specific emetogen, cisplatin. In this review, we will provide an overview of Ca 2+ involvement in the emetic process; discuss the

    Prochlorperazine, a phenothiazine antiemetic, has been reported to protect rats against mercuric chloride (HgCl/sub 2/)-induced nephrotoxicity. Mercuric ion and 12 other divalent metal ions of toxicologic importance inhibit the activity of calmodulin, a ubiquitous intracellular calcium receptor and regulatory protein, at physiologically relevant concentrations. Phenothiazines, including prochlorperazine, are reversible calmodulin antagonists, and as such they interact with divalent calcium at the level of calmodulin. It was of interest therefore to evaluate the comparative effects of several phenothiazines on HgCl/sub 2/-induced nephrotoxicity in rats.

    Full Text Available Cannabinoid hyperemesis syndrome is characterized by chronic, heavy use of cannabis, recurrent episodes of severe nausea and intractable vomiting, and abdominal pain. Temporary relief of symptoms is achieved by taking a hot bath or shower, and resolution of the problem when cannabis use is stopped. Failure to recognize the syndrome leads to misdiagnoses such as psychogenic vomiting, the cyclic vomiting syndrome, an eating disorder or ‘drug-seeking behaviour’, and may lead to extensive, expensive and unproductive investigations, psychiatric referrals and ineffective treatments. Other than stopping cannabis use, there is no proven treatment. Why a substance known for its antiemetic properties should cause such a syndrome is unknown.

    Full Text Available Chronic use of cannabis can result in a syndrome of hyperemesis characterized by cyclical vomiting without any other identifiable causes. Cannabinoid hyperemesis syndrome (CHS is seldom responsive to traditional antiemetic therapies. Despite frequent nausea and vomiting, patients may be reluctant to discontinue use of cannabis. We report a case of severe, refractory CHS with complete resolution of nausea and vomiting after treatment with haloperidol in the outpatient setting. After review of the literature, we believe this is the first reported successful outpatient treatment of CHS and suggests a potential treatment for refractory patients.

    Full Text Available BACKGROUND AND OBJECTIVES To compare the effectiveness of acupressure at P6 point and palonosetron in prevention of postoperative nausea and vomiting in patients undergoing laparoscopic tubal sterilisation. METHODS AND MATERIALS After obtaining institutional ethical clearance and patient consent, this study was conducted during the period of July 2015 to November 2015. Patients undergoing laparoscopic tubal sterilisation belonging to ASA 1 and 2 were included, and patients with hypertension, diabetes neurological diseases, peripheral vascular diseases, local skin diseases, patients on antiemetics and unwilling patients were excluded from the study. Randomisation done by sealed envelope method into two groups of sample size 25 each; group A (acupressure, at P6 point and group B (palonosetron 0.075 mg IV. Acupressure band and Inj palonosetron were given just before the induction of anaesthesia. Episodes of PONV were recorded at 0-2 hours, 2-6 hours, 6- 12 hours and evaluated separately as none, mild, moderate and severe. Rescue antiemetic was given to those who had episode of vomiting. Data analysed using Student ‘t’ test and P value <0.05 considered to be significant. RESULTS Between two group comparisons no significant differences in terms of severity of PONV was observed and Group B showed no incidence of PONV. CONCLUSION Acupressure being non-invasive, non-pharmacological, inexpensive and better patient acceptability can be effectively used as an alternative for the prophylaxis of PONV. However, palonosetron was more effective than acupressure in preventing PONV.

    Full Text Available OBJECTIVE: Ginger effects on (experimental nausea have been described, but also strong placebo effects and sex differences when nausea is involved. The "balanced placebo design" has been proposed to allow better separation of drug and placebo effects. METHODS: Sixty-four healthy participants (32 women were randomly assigned to receive an antiemetic ginger preparation or placebo, and half of each group was told to have received drug or placebo. They were exposed to 5×2 min body rotations to induce nausea. Subjective symptoms and behavioral (rotation tolerance, head movements and physiological measures (electrogastrogram, cortisol were recorded. Groups were balanced for sex of participants and experimenters. RESULTS: Ginger and the information given did not affect any outcome measure, and previous sex differences could not be confirmed. Adding the experimenters revealed a significant four-factorial interaction on behavioral but not on subjective or physiological measures Men who received placebo responded to placebo information when provided by the male experimenter, and to ginger information when provided by the female experimenter. This effect was not significant in women. CONCLUSION: The effects of an antiemetic drug and provided information interact with psychosocial variables of participants and experimenters in reports of nausea.

  2. The medical implications of gastrointestinal vagal afferent pathways in nausea and vomiting.

    Nausea and vomiting are biological systems for defense against food poisoning that are also provoked by numerous drugs (e.g., chemotherapy, anesthesia) and chronic diseases (e.g., cancer, diabetic gastroparesis). The sensory pathways that stimulate nausea and vomiting include vestibular, area postrema, and forebrain inputs, but gastrointestinal vagal afferent fibers arguably play the most prominent role as a first-line defense. Vagal sensory neurons detect toxins that enter the gastrointestinal lumen and transmit information to the hindbrain, leading to nausea (an unconditioned stimulus that serves to facilitate the avoidance of offending foods) and vomiting (a mechanism to clear contents from the stomach). Despite the major importance of these systems to human physiology, progress on the biological basis of nausea and vomiting has been slow - partly because laboratory rats and mice, which represent the largest thrust of preclinical biomedical research, lack a vomiting reflex (although they appear to have indices of nausea, e.g., conditioned food aversion). Several established models are a mainstay of preclinical nausea and vomiting research in academia and pharmaceutical companies, including the dog, cat, ferret, and musk shrew. An argument is made for broader testing across species since each model possesses often unique experimental advantages and sensitivity to emetic and antiemetic agents. This review focuses on the state of knowledge on the neural pathways for nausea and vomiting, behavioral indices of nausea used in preclinical models, role of vagal afferent fibers, current antiemetic and antinausea treatments, and potential future directions.

    Boerhaave's syndrome is a rare disease involving rupture or perforation of the entire layer of the esophagus caused by rapid increase in pressure. When the proper treatment is delayed, the outcome can be fatal, so early diagnosis is important. We experienced a patient of Boerhaave's syndrome during concurrent chemoradiotherapy for hypopharyngeal cancer. We report a 61-year-old male who underwent concurrent chemoradiotherapy for T3N1M0 hypopharyngeal cancer. He had severe chest pain immediately after vomiting. We initially made a differential diagnosis of cardiovascular disease, which needed emergency treatment. However, his general condition deteriorated markedly, and he went into septic shock. We performed a CT after injection of a contrast medium, and confirmed leakage into the thoracic cavity. We diagnosed Boerhaave's syndrome. We started surgery at 19 hours from the onset and found the rupture site by laparotomy. The ruptured esophagus was repaired by simple suturing and covered by the greater omentum, but the patient was not cured of his leakage even after surgery. Recently antiemetics have improved, but we still experience patients who have difficulty due to vomiting when we use cisplatin (CDDP). Furthermore, gastrostomy and opioids as supportive care cause vomiting. Therefore, we must approach antiemetic therapy cautiously, and we should rule out Boerhaave's syndrome quickly when patients have chest pain. (author)

    Full Text Available Christina Ruhlmann, Jørn HerrstedtOdense University Hospital, Department of Oncology, Odense, DenmarkAbstract: Chemotherapy-induced nausea and vomiting (CINV are among the most feared and distressing symptoms experienced by patients with cancer. The knowledge of the pathogenesis and neuropharmacology of CINV has expanded enormously over the last decades, the most significant discoveries being the role of 5-hydroxytryptamine (5-HT3- and neurokinin (NK1 receptors in the emetic reflex arch. This has led to the development of two new classes of antiemetics acting as highly selective antagonists at one of these receptors. These drugs have had a huge impact in the protection from chemotherapy-induced vomiting, whereas the effect on nausea seems to be limited. The first NK1 receptor antagonist, aprepitant, became clinically available in 2003, and casopitant, the second in this class of antiemetics, has now completed phase III trials. This review delineates the properties and clinical use of casopitant in the prevention of CINV.Keywords: casopitant, GW679769, NK1 receptor antagonist, chemotherapy, emesis

    Full Text Available Nausea and vomiting are one of the major complications of chemotherapy for cancers. The aim of this study is to investigate the emetic effects and mechanisms involving serotonin and dopamine of needleless transcutaneous electroacupuncture (TEA at Neiguan (PC6 and Jianshi (PC5 on chemotherapy-induced nausea and vomiting in patients with cancers. Seventy-two patients with chemotherapy were randomly divided into sham-TEA group (sham-TEA, n=34 and TEA group (n=38. TEA was performed at PC 6 and PC 5 (1 h, bid in combination with granisetron. Sham-TEA was delivered at nonacupoints using the same parameters. We found the following. (1 In the acute phase, the conventional antiemetic therapy using Ondansetron effectively reduced nausea and vomiting; the addition of TEA did not show any additive effects. In the delayed phase, however, TEA significantly increased the rate of complete control (P<0.01 and reduced the nausea score (P<0.05, compared with sham-TEA. (2 TEA significantly reduced serum levels of 5-HT and dopamine in comparison with sham-TEA. Those results demonstrate that needleless transcutaneous electroacupuncture at PC6 using a watch-size digital stimulator improves emesis and reduces nausea in the delayed phase of chemotherapy in patients with cancers. This antiemetic effect is possibly mediated via mechanisms involving serotonin and dopamine.

    The purpose of this present study was to evaluate Self-care Improvement through Oncology Nursing (SCION) program to reduce distressing anorexia, nausea, and emesis (ANE) in cancer patients undergoing chemotherapy. Two hundred eight patients receiving chemotherapy with moderate to high emetogenic potential participated in a cluster randomized trial on 14 wards in two German university hospitals. Additionally to standard antiemetic treatment, patients from the intervention wards received the SCION program consisting of four modules: advisory consultation, optimizing emesis prophylaxis, nutrition counseling, and relaxation. Patients from the control group received standard antiemetic treatment and standard care. Primary outcome was the group difference in ANE intensity assessed by Common Terminology Criteria for adverse events (CTCAE). The SCION program did not result in a significant difference in the incidence of ANE symptoms as compared to standard care: mean difference on CTCAE scale was 0.24 pts (95%CI, -1.17 to 1.66 pts; P = 0.733). No difference could be found regarding patients' knowledge of side effects, self-care interventions, and agency. Health-related quality of life was significantly better for patients in the control group (mean difference 10.2 pts; 95%CI, 1.9 to 18.5; P = 0.017). Contrary to our expectations, the groups did not differ in ANE intensity caused by the overall low acute or delayed symptom intensity. Symptom hierarchy in cancer patients alters and challenges nursing interventions targeting the patients' self-care strategies.

    Bloating is commonly reported in gastroparesis, but its prevalence, impact, and associated factors are uninvestigated. We aimed to quantify the prevalence of bloating in gastroparesis and relate its severity to clinical factors and quality of life. Survey, examination, and scintigraphy data were compared in 335 gastroparesis patients from 6 centers of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Gastroparesis Clinical Research Consortium. Bloating severity was stratified using Gastroparesis Cardinal Symptom Index (GCSI) bloating subscale scores. Bloating severity of at least mild (GCSI ≥2) and severe (GCSI ≥4) grades were reported by 76 and 41% of patients, respectively. Bloating severity related to female gender (PDisease etiology, smoking status, and gastric emptying did not relate to bloating subset (P>0.05). Disease-specific quality of life and general measures of well-being were progressively impaired with increasing bloating severity (P=0.01). Probiotic use (P=0.03) and use of antidepressants with significant norepinephrine reuptake inhibitor activity (P=0.045) use related to bloating severity; antiemetic use trended higher with worsening bloating (P=0.06). Bloating is prevalent in gastroparesis and is severe in many individuals. Bloating severity relates to female gender, body weight, and intensity of other symptoms. The symptom impairs quality of life but is not influenced by gastric emptying rates. Antiemetics, probiotics, and antidepressants with significant norepinephrine reuptake inhibitor activity may affect reports of bloating. These findings provide insight into this underappreciated symptom of gastroparesis.

    Gastroparesis patients may have associated psychological distress. This study aimed to measure depression and anxiety in gastroparesis in relation to disease severity, etiology, and gastric retention. Beck Depression Inventory (BDI) and State-Trait Anxiety Inventory (STAI) scores for state (Y1) and trait (Y2) anxiety were obtained from 299 gastroparesis patients from 6 centers of the National Institute of Diabetes and Digestive and Kidney Diseases Gastroparesis Clinical Research Consortium. Severity was investigator graded as grades 1, 2, or 3 and patient reported by Gastroparesis Cardinal Symptom Index (GCSI) scores. Antiemetic/prokinetic medication use, anxiolytic and antidepressant medication use, supplemental feedings, and hospitalizations were recorded. BDI, Y1, and Y2 scores were compared in diabetic vs. idiopathic etiologies and mild (≤20%) vs. moderate (>20-35%) vs. severe (>35-50%) vs. very severe (>50%) gastric retention at 4 h. BDI, Y1, and Y2 scores were greater with increasing degrees of investigator-rated gastroparesis severity (P3.1 vs. ≤3.1 (P3.1 was associated with BDI ≥20 and Y1≥46; antiemetic/prokinetic use was associated with BDI≥20; anxiolytic use was associated with Y1≥46; and antidepressant use was associated with Y2≥44. Higher depression and anxiety scores are associated with gastroparesis severity on investigator- and patient-reported assessments. Psychological dysfunction does not vary by etiology or degree of gastric retention. Psychological features should be considered in managing gastroparesis.

    Serotonin syndrome (SS) is a potentially life-threatening adverse drug reaction that may occur in patients treated with serotonin agonist medications. Medications responsible for serotonin syndrome include commonly prescribed antidepressants, anxiolytics, analgesics, and antiemetics. Veterans with post-traumatic stress disorder (PTSD) are at risk for polypharmacy with serotoninergic medications, given their psychological comorbidities and service-related musculoskeletal injuries. The perioperative period is a particularly vulnerable time owing to the use of high-dose anxiolytics and antiemetics frequently administered in this period, and places PTSD patients at higher risk of SS. Herein, we present the first case of SS in a young veteran with combat-related PTSD following an uncomplicated L5-S1 revision discectomy that highlights the unique set of clinical challenges and dilemmas faced when treating SS in a patient with severe postsurgical pain. As we are likely to encounter increasing numbers of veterans treated for PTSD who require multiple surgical procedures to treat their service-related injuries, health care providers need to be familiar with prevention, recognition, and the clinical challenges in the management of SS in the postoperative period.

    Postoperative nausea and vomiting (PONV) is a common, unpleasant phenomenon and current therapies are not always effective for all patients. Aromatherapy has been suggested as an addition to the available treatment strategies. This review was originally published in 2012 and updated in 2017. The main objective was to establish the efficacy and safety of aromatherapy comparable to standard pharmacological treatments for PONV in adults and children. We searched CENTRAL; MEDLINE; Embase; CINAHL; CAM on PubMed; Informit; LILACS; and ISI Web of Science as well as grey literature sources and the reference lists of retrieved articles up to March 2017. The original search was performed in August 2011. We included all randomized controlled trials (RCTs) and controlled clinical trials (CCTs) where aromatherapy was used to treat PONV. Interventions were all types of aromatherapy compared to placebo or with standard antiemetics. Primary outcomes were severity and duration of PONV. Secondary outcomes were adverse reactions, use of rescue antiemetics and patient satisfaction. Two review authors independently assessed risk of bias in the included studies and extracted data. For dichotomous outcome variables, we used a random-effects model and calculated risk ratio (RR) with associated 95% confidence interval (95% CI). For continuous outcome variables, we used a random-effects model and calculated standardized mean difference (SMD) with associated 95% CI. We used the GRADE software to compile 'Summary of findings' tables. We included seven new studies with 663 participants in the 2017 update; five RCTs and two CCTs. These were added to the nine previously included studies (six RCTs and three CCTs with a total of 373 participants) for a total of 16 included studies and 1036 participants in this updated review. The mean age and range data for all participants were not reported for all studies. We identified two registered trials that met the inclusion criteria for this review

    Antiemetic treatment compliance is important to prevent chemotherapy-induced nausea and vomiting, a feared chemotherapy side effect. NEPA, a new oral fixed combination of netupitant, a highly selective NK1 receptor antagonist (RA), and palonosetron, a second-generation 5-HT3 RA, targets dual antiemetic pathways with a single dose. This study investigated the effect of food intake and age on NEPA pharmacokinetics (PK) and safety. In this open-label, single-center, randomized, phase 1 study, 24 adults (18-45 years) received NEPA in a fed or fasted state during the first treatment period and in the alternative state in the next treatment period. Twelve elderly subjects (≥65 years) received NEPA in a fasted state. Blood samples were taken for netupitant and palonosetron PK analysis. In the fed condition, netupitant plasma exposure increased, whereas palonosetron PK parameters were not affected. Furthermore, elderly subjects showed increased netupitant and palonosetron exposure compared with adults. All adverse events were mild/moderate, with constipation and headache the most common. Although food intake and age altered NEPA PK, dose adjustments were not needed, as netupitant and palonosetron exposure increases did not lead to safety concerns in healthy subjects. © 2015, The American College of Clinical Pharmacology.

    Full Text Available Post-operative nausea and vomiting (PONV is a complication affecting between 20% and 40% of all surgery patients, with high-risk patients experiencing rates of up to 80%. Recent studies and publications have shed light on the uses of alternative treatment for PONV, through their modulation of endogenous opioid neuropeptides and neurokinin ligands. In addition to reducing PONV, hypnosis was reported to be useful in attenuating postoperative pain, anxiety, and contributing to hemodynamic stability. Music therapy has been utilized to deepen the sedation level and decrease patient anxiety, antiemetic and analgesic requirements, hospital length of stay, and fatigue. Isopropyl alcohol and peppermint oil aromatherapy have both been used to reduce postoperative nausea. With correct training in traditional Chinese healing techniques, acupuncture (APu at the P6 acupoint has also been shown to be useful in preventing early PONV, post-discharge nausea and vomiting, and alleviating of pain. Electro-acupuncture (EAPu, as with APu, provided analgesic and antiemetic effects through release of opioid neuropeptides and modulation. These non-pharmacological modalities of treatment contribute to an overall patient wellbeing, assisting in physical and emotional healing.

    Nausea and vomiting are the most often observed symptoms in the course of the early radiation syndrome. Their prevention has long been difficult because of the low effectiveness and side-effects of most antiemetics. There is a clear evidence that 5HT 3 receptor antagonists such as ondansetron and granisetron are highly effective to prevent radiation-induced emesis without any side-effect. We studied the prophylactic effectiveness of their oral administration to macacus cynomolgus, for mixed neutron-gamma whole-body exposure, tat high dose rates. Doses of 4 mg of ondansetron or 1 mg of granisetron were administered before, or after, or both before and after irradiation. The treatment was effective when administered both before and after radiation exposure. It was significant but incomplete if administered once. Post-irradiation administration is interesting, particularly in case of accident. Both antiemetic drugs were well tolerated. Their effectiveness and tolerance are apparently comparable. The 5HT 3 receptor antagonists represent a much improved treatment for radiation-induced nausea and vomiting by completely inhibiting emesis, if administered before and after irradiation. Unwanted sedation and extra-pyramidal side-effects, usually associated with the clinical use of D 2 receptor antagonists, were not observed. (authors). 40 refs., 5 tabs

    Full Text Available Stomach diseases have an important place in the clinical pathology of dogs. Etiological factors can be nutritive, chemical, or infective, but treatment implies certain common general principles and a certain number of therapy protocols which are most often used. On the other hand, a part of the medicines used in the pharmacotherapy of stomach diseases in dogs are taken from the palette of medicines intended for human use, so that a regular dosage and regime of implementation are the main precondition for the success of the applied therapy. Drugs used in the treatment of stomach diseases include antiemetics, prokinetics, antacids, mucoprotectives, anticholinergics, H2-antagonists, proton pump inhibitors, semisynthetic derivatives of prostaglandin E1, and others. The therapy of stomach diseases implies the simultaneous application of several drugs from different pharmacodynamic groups (for instance, an antiemetic, a prokinetic, an antacid, and an Hg antagonist or a proton pump inhibitor when it is necessary to establish a correct regime of implementation because of possible interaction, which will also be discussed in this work.

    Intraoperative vomiting leads to serious respiratory complications that could influence the surgical decision-making process for awake craniotomy. However, the use of antiemetics is still limited in Japan. The aim of this study was to investigate the effect of prophylactically administered single low-dose dexamethasone on the incidence of vomiting during awake craniotomy. The frequency of hyperglycemia was also examined. We conducted a retrospective case review of awake craniotomy for glioma resection between 2012 and 2015. Of the 124 patients, 91 were included in the analysis. Dexamethasone was not used in 43 patients and the 48 remaining patients received an intravenous bolus of 4.95 mg dexamethasone at anesthetic induction. Because of stable operating conditions, no one required conscious sedation throughout functional mapping and tumor resection. Although dexamethasone pretreatment reduced the incidence of intraoperative vomiting (P = 0.027), the number of patients who complained of nausea was comparable (P = 0.969). No adverse events related to vomiting occurred intraoperatively. Baseline blood glucose concentration did not differ between each group (P = 0.143), but the samples withdrawn before emergence (P = 0.018), during the awake period (P craniotomy cases. However, as even a small dose of dexamethasone increases the risk for hyperglycemia, antiemetic prophylaxis with dexamethasone should be administered after careful consideration. Monitoring of perioperative blood glucose concentration is also necessary.

    The main objective of the present research work was to develop a bilayer tablet of metoclopramide hydrochloride (MTH) and diclofenac sodium (DS) in separate layers to avoid incompatibility and thus to maximize the efficacy of both drugs in combination for the effective treatment of migraine headaches. MTH and DS were formulated as immediate and sustained release layers respectively. In vitro dissolution kinetic studies of an optimized (D10) batch of DS in both sustained release layer and bilayer tablet forms show good linearity of regression coefficient 0.9773 (first order equation). The results reveal that an optimized immediate release layer (M5) of MTH and a sustained release layer (D10) of DS might be suitable for the treatment of migraine by sequential release of the two drugs in a bilayer tablet. Migraine is a type of recurring headache of moderate to severe intensity associated with gastrointestinal, neurological, and autonomic symptoms. In migraine, a combination of pretreatment with antiemetics is required for symptomatic treatment, when nausea and vomiting are severe. In our present research, we have selected the metoclopramide hydrochloride (MTH) active ingredient for study because it has an antiemetic effect and is a prokinetic agent. MTH is more effective to counteract gastric stasis associated with migraine, and it enhances the rate of absorption of non-steroidal anti-inflammatory drugs (NSAIDs). In the present investigation we combine MTH and a second active ingredient, diclofenac sodium, as a formulated bilayer tablet to prevent degradation of MTH.

    Purpose: The purpose of this study was to investigate acute normal tissue damage of low irradiation doses to the healthy, adult central nervous system (CNS) using neuropsychological testing of attention functions. Methods and Materials: Neuropsychological testing (IQ, attention [modified Trail-Making Test A, Digit Symbol Test, D2 Test, Wiener Determination Machine]) was used to examine 40 patients (43 ± 10 years) before and immediately after the first fraction (1.2 Gy) of hyperfractionated total body irradiation (TBI) at the University of Heidelberg. The patients received antiemetic premedication. Test results are given as mean percentiles ± standard deviation, with 50 ± 34 being normal. Thirty-eight control patients (53 ± 15 years) were studied to quantify the influence of hospitalization, stress, and repeated testing. Results: The patients showed normal baseline test results (IQ = 101 ± 14, attention = 54 ± 28) and no decrease in test results after 1.2 Gy TBI. Attention functions improved (66 ± 25) corresponding to a practice effect of repeated testing that was seen in the control group, although alternate versions of the tests were used (IQ = 104 ± 10, attention before = 42 ± 29, attention after = 52 ± 31). Conclusion: Our data show no deterioration of neuropsychologic test results acutely after 1.2 Gy whole body exposure in adult patients without CNS disease receiving antiemetic medication

    Full Text Available Bacopa monnieri (BM, family Scrophulariaceae is used in several traditional systems of medicine for the management of epilepsy, depression, neuropathic pain, sleep disorders and memory deficits. The present study investigated the potential of BM methanol (BM-MetFr and BM n-butanol fractions (BM-ButFr to reduce chemotherapy-induced emesis in Suncus murinus (house musk shrew. Cisplatin (30 mg/kg, i.p. reliably induced retching and/or vomiting over a 2 day period. BM-MetFr (10–40 mg/kg, s.c. and BM-ButFr (5–20 mg/kg, s.c. antagonized the retching and/or vomiting response by ∼59.4% (p  0.05. In conclusion, the n-butanol fractions of BM have anti-emetic activity comparable with palonosetron and MPG. BM may be useful alone or in combination with other anti-emetic drugs for the treatment of chemotherapy-induced emesis in man.

    A prospective trial was performed to better assess the risk of nausea and vomiting and the rescue value of tropisetron (TRO), a 5-HT 3 receptor antagonist, in 88 patients undergoing fractionated radiotherapy to the abdomen or to large supradiaphragmatic fields and failing a first anti-emetic trial with metoclopramide (MET). Nausea was graded 0 (absent), 1 (mild), 2 (moderate) and 3 (severe). Nausea requiring anti-emetics (≥ grade 2) was present in 64% of the patients. MET was able to control nausea (≤ grade 1) in 26 of 58 patients (45%) who developed ≥ grade 2 nausea during radiation treatment (2 patients vomiting without nausea included). 34 patients required TRO, and 31 experienced immediate relief. However, nausea (≥ grade 2) recurred in 7 patients from 1 to 3 weeks after starting TRO. Sex, age, field type and field size (cm 2 ) did not influence the incidence and severity of nausea and vomiting. Only 24/88 patients vomited after starting radiotherapy. MET helped to eliminate emesis in one third of these patients. TRO helped to control vomiting in 73% of the salvaged patients. Constipation was observed in 8 patients on TRO and was a reason to stop the medication in 4 cases. (author)

    Delayed postpartum haemorrhage due to uterine atony after caesarean section was occurring in women in our recovery area despite many of them already having an oxytocin infusion running to prevent such a problem. We therefore decided to compare the incidence of such problems for a 2-month period before and after altering our uterotonic policy: in addition to the routine bolus dose of 5 units of oxytocin after delivery of the baby, we added 500 microg of intramuscular ergometrine during abdominal closure. We noticed a reduced number of massive postpartum haemorrhages due to an atonic uterus in the recovery room but an increased incidence of nausea and vomiting. No prophylactic anti-emetic was given during this pilot study. This small study suggests that 50 women would need to be given ergometrine at caesarean section to prevent one delayed massive haemorrhage from uterine atony and four extra women would suffer with vomiting. We feel this is reasonable and now use a prophylactic anti-emetic as well as delaying the ergometrine until closure of the rectus sheath which reduces the incidence of nausea and vomiting.

    Full Text Available Background: postoperative nausea and vomiting (PONV frequently hampers implementation of ambulatory surgery in spite of so many antiemetic drugs and regimens. Aims: the study was carried out to compare the efficacy of Ramosetron and Ondansetron in preventing PONV after ambulatory surgery. Setting and Design: it was a prospective, double blinded, and randomized controlled study. Methods: 124 adult patients of either sex, aged 25-55, of ASA physical status I and II, scheduled for day care surgery, were randomly allocated into Group A [(n=62 receiving (IV Ondansetron (4 mg] and Group B [(n=62 receiving IV Ramosetron (0.3 mg] prior to the induction of general anesthesia in a double-blind manner. Episodes of PONV were noted at 0.5, 1, 2, 4 h, 6 , 12, and 18 h postoperatively. Statistical Analysis and Results: statistically significant difference between Groups A and B (P <0.05 was found showing that Ramosetron was superior to Ondansetron as antiemetic both regarding frequency and severity. Conclusion: it was evident that preoperative prophylactic administration of single dose IV Ramosetron (0.3 mg has better efficacy than single dose IV Ondansetron (4 mg in reducing the episodes of PONV over 18 h postoperatively in patients undergoing day-care surgery under general anesthesia.

    Metoclopramide is a drug which has experienced worldwide use in the clinic for over 30 years as an antiemetic. Recently, it has also been shown to possess radio- and chemosensititzing properties in both animal tumour models and humans at the higher dose of 2 mg/kg. Two new metoclopramide formulations are being clinically developed and they differ mainly in whether the pH of their formulations are acidic (pH 2.5-3.5) or neutral (pH 6.5-7.0). Here we report that intramuscular administration of neutral metoclopramide is about 100% bioavailable, safer and with reduced side effects compared to acidic metoclopramide delivered by intramuscular injection to rats within the dose ranger of 3.5 to 14 mg/kg. The intramuscular administration of metoclopramide was also about 100% bioavailable compared to the intravenous route of administration. Furthermore, neutral metoclopramide had significantly decreased affinity for dopamine D 2 receptors and increased affinity for 5-hydroxytryptamine 3 receptors, but the radiosensitizing potency was the same, when compared to equimolar concentrations of acidic metoclopramide. Taken together these data support the continued development of neutral metoclopramide for high dose intramuscular administration of metoclopramide for future clinical use as both an antiemetic and radiosensitizer.

    Background: A significant number of patients receiving radiotherapy experience the distressing side effects of emesis and nausea. These symptoms are some of the most distressing problems for the patients influencing their quality of life. Methods: International study results concerning radiotherapy-induced emesis are demonstrated. A German multicenter questionnaire examining the strategies to prevent or to treat radiotherapy-induced nausea and emesis is presented. An international analysis concerning incidence of emesis and nausea in fractionated radiotherapy patients is discussed. Finally the consensus of the consensus conference on antiemetic therapy from the Perugia International Cancer Conference V is introduced. Results: Untreated emesis can lead to complications like electrolyte disorders, dehydration, metabolic disturbances and nutrition problems with weight loss. Prophylactic antiemetics are often given to patients receiving single high-dose radiotherapy to the abdomen. A survey has revealed that antiemetic prophylaxis is not routinely offered to the patients receiving fractionated radiotherapy. However, there is a need for an effective treatment of emesis for use in this group of patients, too. In 20% of patients nausea and emesis can cause a treatment interruption because of an inadequate control of symptoms. Like in chemotherapy strategies there exist high, moderate, and low emetogenic treatment regimens in radiotherapy as well. The most emetogenic potential has the total body irradiation followed by radiotherapy to the abdomen. Radiotherapy induced emesis can be treated effectively with conventional antiemetics up to 50%. Conclusions: Studies with total body irradiation, fractionated treatment and high-dose single exposures have cleary demonstrated the value of 5-HT3-receptor antagonist antiemetics. There is a response between 60 and 97%. There is no difference in the efficacy of the different 5-HT3-antagonists. High-risk patients should be prophylactic

    Postoperative nausea and vomiting is a common and unpleasant phenomenon and current therapies are not always effective for all patients. Aromatherapy has been suggested as a possible addition to the available treatment strategies. This review sought to establish what effect the use of aromatherapy has on the severity and duration of established postoperative nausea and vomiting and whether aromatherapy can be used with safety and clinical effectiveness comparable to standard pharmacological treatments. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 3); MEDLINE; EMBASE; CINAHL; CAM on PubMed; Meditext; LILACS; and ISI Web of Science as well as grey literature sources and the reference lists of retrieved articles. We conducted database searches up to August 2011. We included all randomized controlled trials (RCTs) and controlled clinical trials (CCTs) where aromatherapy was used to treat postoperative nausea and vomiting. Interventions were all types of aromatherapy. Aromatherapy was defined as the inhalation of the vapours of any substance for the purposes of a therapeutic benefit. Primary outcomes were the severity and duration of postoperative nausea and vomiting. Secondary outcomes were adverse reactions, use of rescue anti-emetics and patient satisfaction with treatment. Two review authors assessed risk of bias in the included studies and extracted data. As all outcomes analysed were dichotomous, we used a fixed-effect model and calculated relative risk (RR) with associated 95% confidence interval (95% CI). The nine included studies comprised six RCTs and three CCTs with a total of 402 participants. The mean age and range data for all participants were not reported for all studies. The method of randomization in four of the six included RCTs was explicitly stated and was adequate. Incomplete reporting of data affected the completeness of the analysis.

    Safe, effective and convenient antiemetic regimens that preserve benefit over repeated cycles are needed for optimal supportive care during cancer treatment. NEPA, an oral fixed-dose combination of netupitant, a highly selective NK1 receptor antagonist (RA), and palonosetron (PALO), a distinct 5-HT3 RA, was shown to be superior to PALO in preventing chemotherapy-induced nausea and vomiting after a single cycle of highly (HEC) or moderately (MEC) emetogenic chemotherapy in recent trials. This study was designed primarily to assess the safety but also to evaluate the efficacy of NEPA over multiple cycles of HEC and MEC. This multinational, double-blind, randomized phase III study (NCT01376297) in 413 chemotherapy-naïve patients evaluated a single oral dose of NEPA (NETU 300 mg + PALO 0.50 mg) given on day 1 with oral dexamethasone (DEX). An oral 3-day aprepitant (APR) regimen + PALO + DEX was included as a control (3:1 NEPA:APR randomization). In HEC, DEX was administered on days 1-4 and in MEC on day 1. Safety was assessed primarily by adverse events (AEs), including cardiac AEs; efficacy by complete response (CR: no emesis, no rescue). Patients completed 1961 total chemotherapy cycles (76% MEC, 24% HEC) with 75% completing ≥4 cycles. The incidence/type of AEs was comparable for both groups. Most frequent NEPA-related AEs included constipation (3.6%) and headache (1.0%); there was no indication of increasing AEs over multiple cycles. The majority of AEs were mild/moderate and there were no cardiac safety concerns based on AEs and electrocardiograms. The overall (0-120 h) CR rates in cycle 1 were 81% and 76% for NEPA and APR + PALO, respectively, and antiemetic efficacy was maintained over repeated cycles. NEPA, a convenient single oral dose antiemetic targeting dual pathways, was safe, well tolerated and highly effective over multiple cycles of HEC/MEC. © The Author 2014.

    Antiemetic guidelines recommend co-administration of agents that target multiple molecular pathways involved in emesis to maximize prevention and control of chemotherapy-induced nausea and vomiting (CINV). NEPA is a new oral fixed-dose combination of 300 mg netupitant, a highly selective NK1 receptor antagonist (RA) and 0.50 mg palonosetron (PALO), a pharmacologically and clinically distinct 5-HT3 RA, which targets dual antiemetic pathways. This multinational, randomized, double-blind, parallel group phase III study (NCT01339260) in 1455 chemotherapy-naïve patients receiving moderately emetogenic (anthracycline-cyclophosphamide) chemotherapy evaluated the efficacy and safety of a single oral dose of NEPA versus a single oral dose (0.50 mg) of PALO. All patients also received oral dexamethasone (DEX) on day 1 only (12 mg in the NEPA arm and 20 mg in the PALO arm). The primary efficacy end point was complete response (CR: no emesis, no rescue medication) during the delayed (25-120 h) phase in cycle 1. The percentage of patients with CR during the delayed phase was significantly higher in the NEPA group compared with the PALO group (76.9% versus 69.5%; P = 0.001), as were the percentages in the overall (0-120 h) (74.3% versus 66.6%; P = 0.001) and acute (0-24 h) (88.4% versus 85.0%; P = 0.047) phases. NEPA was also superior to PALO during the delayed and overall phases for all secondary efficacy end points of no emesis, no significant nausea and complete protection (CR plus no significant nausea). NEPA was well tolerated with a similar safety profile as PALO. NEPA plus a single dose of DEX was superior to PALO plus DEX in preventing CINV following moderately emetogenic chemotherapy in acute, delayed and overall phases of observation. As a fixed-dose antiemetic drug combination, NEPA along with a single dose of DEX on day 1 offers guideline-based prophylaxis with a convenient, single-day treatment. © The Author 2014.

Although chemotherapy-induced nausea and vomiting (CINV prevalence is high, treatment remains difficult. Palonosetron is a 5-hydroxytryptamine receptor antagonist (5-HT3RA approved for treatment of CINV. The purpose of this review is to discuss existing and emerging therapeutic options, and examine studies focusing on palonosetron with regards to efficacy, pharmacology, tolerability, safety, and patient-derived outcomes.Methods: A literature search was conducted using Ovid MEDLINE and EMBASE to identify relevant studies using palonosetron alone or in combination with other antiemetics. Studies were extracted if they included complete response (CR, complete control (CC, no nausea, no vomiting, and no rescue medications as an endpoint. Studies were also included if safety endpoints were examined.Results: Palonosetron alone has been shown to improve CR and CC rates for patients receiving low, moderate, or high emetogenic chemotherapy. Rates were further improved with the addition of dexamethasone, a corticosteroid. Furthermore, the addition of neurokinin-1 receptor antagonists, such as netupitant markedly improved efficacy profiles compared to palonosetron alone. Aprepitant is an antiemetic that has exhibited positive results in combination with palonosetron. Recently, a new drug consisting of netupitant and palonosetron (NEPA has demonstrated significantly more efficacious prevention of CINV. Regardless of the combination, palonosetron has been well tolerated. The most common adverse events were constipation, headache, fatigue, and dizziness, with the majority of patients describing them as only mild

    Standard prophylaxis for chemotherapy-induced nausea and vomiting (CINV) with highly emetogenic and anthracycline-cyclophosphamide-based chemotherapy includes a 5-hydroxytryptamine-3 receptor antagonist, a neurokinin-1 receptor antagonist (NK1RA), and corticosteroid therapy. NEPA is a fixed combination of netupitant and palonosetron. The primary objective of this analysis was to document the safety profile, including cardiac safety, of NEPA + dexamethasone in comparison with current therapies across all phase II/III trials. This pooled analysis was based on data from 3,280 patients in 4 randomized, double-blind clinical trials. Patients were categorized into 1 of 3 pooled groups on the basis of actual treatment received: NEPA + dexamethasone, palonosetron + dexamethasone, and aprepitant + ondansetron/palonosetron + dexamethasone. Safety was assessed by number and frequency of adverse events (AEs) and changes from baseline electrocardiogram measures. Most patients were female and younger than 65 years of age. Demographic characteristics varied among studies and pooled groups. Frequencies of treatment-emergent AEs (TEAEs) and treatment-related AEs (TRAEs) were similar across groups. TEAEs were mostly mild and consistent with expected chemotherapy and disease-related AEs (hematologic events, hair loss, general weakness). TRAEs in ≥2% of patients were headache and constipation. Frequencies of cardiac TEAEs were similar across groups, with QT prolongation (1.6%), tachycardia (1.1%), and dyspnea (0.9%) the most common. Serious cardiac TEAEs were rare. NEPA was well-tolerated, with an AE profile as expected for the regimen. Sample size, demographic characteristics, study design, chemotherapy, and antiemetic regimen differences across the four studies may have contributed to differences in frequencies of neutropenia and alopecia. Adding an NK1RA to a CINV prophylaxis regimen can improve outcomes without additional toxicity. Supportive care for cancer should ideally be

    Context Gastroenteritis remains a leading cause of childhood morbidity. Objective Because prior reviews have focused on isolated symptoms and studies conducted in developing countries, this study focused on interventions commonly considered for use in developed countries. Intervention specific, patient-centered outcomes were selected. Data Sources MEDLINE, EMBASE, the Cochrane Database of Systematic Reviews, trial registries, grey literature, and scientific meetings. Study Selection Randomized controlled trials, conducted in developed countries, of children aged gastroenteritis, performed in emergency department or outpatient settings which evaluated oral rehydration therapy (ORT), antiemetics, probiotics or intravenous fluid administration rate. Data Extraction The study was conducted in accordance with the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA guidelines. Data were independently extracted by multiple investigators. Analyses employed random effects models. Results 31 trials (4,444 patients) were included. ORT: Compared with intravenous rehydration, hospitalization (RR 0.80, 95%CI 0.24, 2.71) and emergency department return visits (RR 0.86, 95%CI 0.39, 1.89) were similar. Antiemetics: Fewer children administered an antiemetic required intravenous rehydration (RR 0.40, 95%CI 0.26, 0.60) While the data could not be meta-analyzed, three studies reported that ondansetron administration does increase the frequency of diarrhea. Probiotics: No studies reported on the primary outcome, three studies evaluated hospitalization within 7 days (RR 0.87, 95%CI 0.25, 2.98). Rehydration: No difference in length of stay was identified for rapid vs. standard intravenous or nasogastric rehydration. A single study found that 5% dextrose in normal saline reduced hospitalizations compared with normal saline alone (RR 0.70, 95% CI 0.53, 0.92). Conclusions There is a paucity of patient-centered outcome evidence to support many interventions. Since ORT is

    Full Text Available Nausea and vomiting remain among the most feared side effects of chemotherapy for cancer patients. Significant progress has been made in the last 15 years in developing more effective and better-tolerated measures to minimize chemotherapy-induced nausea and vomiting (CINV. During the 1990s, the selective 5-hydroxytryptamine receptor antagonists were first introduced for the treatment of CINV, and resulted in more effective and better tolerated treatment of CINV. Despite recent progress, however, a significant number of patients still develop CINV, particularly during the 2-5-day period (delayed emesis following chemotherapy. There is evidence that this may be an underappreciated problem on the part of some caregivers. Recently, two new antiemetics, aprepitant, the first member of the neurokinin-1 antagonists, and palonosetron, a second-generation 5-hydroxytryptamine receptor antagonist, received regulatory approval in the U.S. Both represent useful additions to the therapeutic armamentarium for the management of CINV.

Irinotecan plus bevacizumab is a treatment frequently used in MG, but is associated with low (55% CINV complete response (CR; no emesis or use of rescue antiemetic with commonly prescribed ondansetron. A single-arm Phase II trial was conducted in MG patients to determine the efficacy of intravenous PAL (0.25 mg and dexamethasone (DEX; 10 mg received in conjunction with biweekly irinotecan–bevacizumab treatment. The primary end point was the proportion of subjects achieving acute CINV CR (no emesis or antiemetic ≤24 hours postchemotherapy.

    The chemotherapeutic drug cisplatin is associated with severe gastrointestinal toxicity that can last for several days. A recent strategy to treat the nausea and emesis includes the combination of a 5-HT 3 receptor antagonist, a glucocorticoid, and an NK 1 receptor antagonist. The present studies explore the use of the selective noradrenaline reuptake inhibitors, (R)-sila-venlafaxine, (R,R)-reboxetine and (S,S)-reboxetine to prevent cisplatin (5 mg/kg, i.p.)-induced acute (0-24 h) and delayed (24-72 h) emesis in ferrets. The positive control regimen of ondansetron and dexamethasone, both at 1 mg/kg/8 h, reduced acute and delayed emesis by 100 (P 0.05). In conclusion, the studies provide the first evidence for an anti-emetic potential of noradrenaline reuptake inhibitors to reduce chemotherapy-induced acute and delayed emesis

    The involvement of 5-hydroxytryptamine (5-HT) 5-HT 3 receptors in the mechanisms of severe emesis evoked by cytotoxic drugs or by total body irradiation have been studied in ferrets. Anti-emetic compounds tested were domperidone (a dopamine antagonist), metoclopramide (a gastric motility stimulant and dopamine antagonist at conventional doses, a 5-HT 3 receptor antagonist at higher doses) and BRL 24924 (a potent gastric motility stimulant and a 5-HT 3 receptor antagonist). Domperidone or metoclopramide prevented apomorphine-evoked emesis, whereas BRL 24924 did not. Similar doses of domperidone did not prevent emesis evoked by cis-platin or by total body irradiation, whereas metoclopramide or BRL 24924 greatly reduced or prevented these types of emesis. Metoclopramide and BRL 24924 also prevented emesis evoked by a combination of doxorubicin and cyclophosphamide. These results are discussed in terms of a fundamental role for 5-HT 3 receptors in the mechanisms mediating severely emetogenic cancer treatment therapies. (author)

    Full Text Available Nausea and vomiting remain among the most feared side effects of chemotherapy for cancer patients. Significant progress has been made in the last 15 years in developing more effective and better-tolerated measures to minimize chemotherapy-induced nausea and vomiting (CINV. During the 1990s, the selective 5-hydroxytryptamine receptor antagonists were first introduced for the treatment of CINV, and resulted in more effective and better tolerated treatment of CINV. Despite recent progress, however, a significant number of patients still develop CINV, particularly during the 2-5-day period (delayed emesis following chemotherapy. There is evidence that this may be an underappreciated problem on the part of some caregivers. Recently, two new antiemetics, aprepitant, the first member of the neurokinin-1 antagonists, and palonosetron, a second-generation 5-hydroxytryptamine receptor antagonist, received regulatory approval in the U.S. Both represent useful additions to the therapeutic armamentarium for the management of CINV.

    Recommendations based on radiation dose and physiologic response are made for treatment of the hematopoietic syndrome. Therapy includes treatment with hematopoietic cytokines, blood transfusion, and stem-cell transplantation in selected cases. Additional medical management based on the evolution of clinical signs and symptoms includes the use of antimicrobial agents (quinolones, antiviral therapy, and antifungal agents), antiemetic agents, and analgesic agents. Because of the strong psychological impact of a possible radiation exposure, psychosocial support will be required for those exposed, regardless of the dose, as well as for family and friends. Treatment of pregnant women must account for risk to the fetus. For terrorist or accidental events involving exposure to radioiodines, prophylaxis against malignant disease of the thyroid is also recommended, particularly for children and adolescents. (authors)

    Children undergoing tonsillectomy remain at risk for postoperative pain, respiratory depression, and postoperative nausea and vomiting (PONV), presenting unique challenges for the postanesthesia nurse. This prospective, observational study examined the relationships between and factors contributing to these outcomes in 102 children after tonsillectomy. All children received an intraoperative opioid and one or more antiemetics. The majority (67%) experienced moderate to severe pain, 27% experienced a respiratory event, and 7% had PONV. Children with moderate to severe pain received similar intraoperative opioid dosages, increased postoperative opioids (P breathing, or opioid use. This study suggests that children undergoing tonsillectomy experience significant pain and respiratory events. Further study examining nonopioid treatments are warranted to determine the best practices for this high-risk group of children. Copyright © 2011 American Society of PeriAnesthesia Nurses.

    Objective To quantify the antiemetic efficacy and adverse effects of cannabis used for sickness induced by chemotherapy. Design Systematic review. Data sources Systematic search (Medline, Embase, Cochrane library, bibliographies), any language, to August 2000. Studies 30 randomised comparisons of cannabis with placebo or antiemetics from which dichotomous data on efficacy and harm were available (1366 patients). Oral nabilone, oral dronabinol (tetrahydrocannabinol), and intramuscular levonantradol were tested. No cannabis was smoked. Follow up lasted 24 hours. Results Cannabinoids were more effective antiemetics than prochlorperazine, metoclopramide, chlorpromazine, thiethylperazine, haloperidol, domperidone, or alizapride: relative risk 1.38 (95% confidence interval 1.18 to 1.62), number needed to treat 6 for complete control of nausea; 1.28 (1.08 to 1.51), NNT 8 for complete control of vomiting. Cannabinoids were not more effective in patients receiving very low or very high emetogenic chemotherapy. In crossover trials, patients preferred cannabinoids for future chemotherapy cycles: 2.39 (2.05 to 2.78), NNT 3. Some potentially beneficial side effects occurred more often with cannabinoids: “high” 10.6 (6.86 to 16.5), NNT 3; sedation or drowsiness 1.66 (1.46 to 1.89), NNT 5; euphoria 12.5 (3.00 to 52.1), NNT 7. Harmful side effects also occurred more often with cannabinoids: dizziness 2.97 (2.31 to 3.83), NNT 3; dysphoria or depression 8.06 (3.38 to 19.2), NNT 8; hallucinations 6.10 (2.41 to 15.4), NNT 17; paranoia 8.58 (6.38 to 11.5), NNT 20; and arterial hypotension 2.23 (1.75 to 2.83), NNT 7. Patients given cannabinoids were more likely to withdraw due to side effects 4.67 (3.07 to 7.09), NNT 11. Conclusions In selected patients, the cannabinoids tested in these trials may be useful as mood enhancing adjuvants for controlling chemotherapy related sickness. Potentially serious adverse effects, even when taken short term orally or intramuscularly, are likely

    INTRODUCTION: 5-Hydroxytryptamine3-receptor antagonists (5-HT3-RA) are the most widely used antiemetics in oncology, and although tolerability is high, QTC prolongation has been observed in some patients. AREAS COVERED: The purpose of this article is to outline the risk of cardiac adverse events...... in clinical trials. Furthermore, polypharmacy is frequent and drug-drug interactions between chemotherapy and other QTc-prolonging drugs may influence the pharmacokinetics and pharmacodynamics of the 5-HT3-RAs. During the next 10 - 15 years a huge increase in the number of cancer patients is expected......, primarily in the group of 65-plus-year old. Therefore it will be crucial to address the incidence of cardiac AEs in cancer patients with known heart disease receiving chemotherapy and a 5-HT3 RA for the prophylaxis of CINV....

  1. Cannabinoid Hyperemesis Syndrome: A Paradoxical Cannabis Effect

    Directory of Open Access Journals (Sweden)

    Ivonne Marie Figueroa-Rivera

    2015-01-01

    Full Text Available Despite well-established antiemetic properties of marijuana, there has been increasing evidence of a paradoxical effect in the gastrointestinal tract and central nervous system, given rise to a new and underrecognized clinical entity called the Cannabinoid Hyperemesis Syndrome. Reported cases in the medical literature have established a series of patients exhibiting a classical triad of symptoms: cyclic vomiting, chronic marijuana use, and compulsive bathing. We present a case of a 29-year-old man whose clinical presentation strongly correlates with cannabinoid hyperemesis syndrome. Despite a diagnosis of exclusion, this syndrome should be considered plausible in the setting of a patient with recurrent intractable vomiting and a strong history of cannabis use as presented in this case.

    Full Text Available Intestinal mucus accumulation is a very rare situation observed in some solid tumors, intestinal inflammation, mucosal hyperplasia, elevated intestinal pressure, and various other diseases. However, it has never been described in acute myeloblastic leukemia. The pathogenesis of intestinal mucus accumulation is still not clear. Here, we report a 14-year-old girl with acute myeloblastic leukemia and febrile neutropenia in addition to typhlitis. She was also immobilized due to joint contractures of the lower extremities and had intestinal mucus accumulation, which was, at first, misdiagnosed as intestinal parasitosis. We speculate that typhlitis, immobilization and decreased intestinal motility due to usage of antiemetic drugs might have been the potential etiologic factors in this case. However, its impact on prognosis of the primary disease is unknown.

    Wilkie, Gianna; Sakr, Bachir; Rizack, Tina

    2016-03-17

    Medicinal marijuana use is currently legal in 23 states and the District of Columbia. As more states approve marijuana use for medical indications, physicians will be asked by their patients for more information regarding the risks and benefits of use. This article reviews the history, adverse effects, and proposed mechanisms of action of marijuana and summarizes the available literature regarding symptom relief and therapeutic value in patients with cancer. Marijuana in oncology may have potential for use as an antiemetic, for refractory cancer pain, and as an antitumor agent. However, much of the data are based on animal data, small trials, or are outdated. More research is needed in all areas related to the therapeutic use of marijuana in oncology.

    Chemotherapy-induced nausea and vomiting (CINV) is a significant clinical issue which affects patients' quality of life as well as treatment decisions. Significant improvements in the control of CINV have occurred in the past 15 years with the introduction of new antiemetic agents: 5-HT3 receptor antagonists, tachykinin NK1 receptor antagonists and olanzapine. Aprepitant was the first NK1 receptor antagonist introduced (2003) for the prevention of CINV in combination with a 5-HT3 receptor antagonist and dexamethasone. Two additional NK1 receptor antagonists, netupitant and rolapitant, were approved by the FDA in 2014 and 2015, respectively. A description of rolapitant and its role in CINV will be presented, along with a comparison to the other NK1 receptor antagonists, aprepitant and netupitant.

    Chemotherapy-induced nausea and vomiting (CINV), both acute and delayed, has a dramatic effect on the well-being and quality of life of patients with cancer. Improved understanding of the mechanisms involved in CINV has led to the development of agents targeting the 5-HT3 receptor as well as the NK-1 receptor. Antiemetic prophylaxis given to patients receiving highly emetogenic chemotherapy combines agents blocking the 5-HT3 and NK-1 receptors along with corticosteroids given regularly and repeatedly. Rolapitant is a long-acting NK-1 receptor antagonist with proven efficacy in controlling CINV as part of the prophylaxis regimen. This review will detail the clinical efficacy and safety of rolapitant in the treatment of patients with cancer receiving highly or moderately emetogenic chemotherapy.

    2010-06-01

    Mallory-Weiss syndrome is relatively common and is involved in 3 to 10% of cases of upper gastrointestinal bleeding. Most of the time, the hemorrhage is mild and stops spontaneously. Clinical suspicion requires confirmation by an upper gastrointestinal endoscopy, which must be performed rapidly after the first hematemesis. Mallory-Weiss syndrome is diagnosed when it shows a longitudinal mucosal tear at the esophagogastric junction. Patients with active bleeding or signs of recent bleeding at endoscopy need immediate endoscopic treatment for hemostasis. Band ligation seems to be the most efficient procedure for primary hemostasis and for preventing recurrent bleeding. The use of proton pump inhibitors and antiemetics seems logical in all cases, although nothing in the literature demonstrates their efficacy. Copyright 2009 Elsevier Masson SAS. All rights reserved.

  8. Managing hyperemesis gravidarum: a multimodal challenge

    Science.gov (United States)

    2010-01-01

    Up to 90% of pregnant women experience nausea and vomiting. When prolonged or severe, this is known as hyperemesis gravidarum (HG), which can, in individual cases, be life threatening. In this article the aetiology, diagnosis and treatment strategies will be presented based on a selective literature review. Treatment strategies range from outpatient dietary advice and antiemetic drugs to hospitalization and intravenous (IV) fluid replacement in persistent or severe cases. Alternative methods, such as acupuncture, are not yet evidence based but sometimes have a therapeutic effect. In most cases, the condition is self limiting and subsides by around 20 weeks gestation. More severe forms require medical intervention once other organic causes of nausea and vomiting have been excluded. In addition, a psychosomatic approach is often helpful. In view of its potential complexity, general practitioners and obstetricians should be well informed about HG and therapy should be multimodal. PMID:20633258

    Hyperemesis gravidarum (HG) is a severe and prolonged form of nausea and/or vomiting during pregnancy. HG affects 0.3-2% of pregnancies and is defined by dehydration, ketonuria, and more than 5% body weight loss. Initial pharmacologic treatment for HG includes a combination of doxylamine and pyridoxine. Additional interventions include ondansetron or dopamine antagonists such as metoclopramide or promethazine. The options are limited for women who are not adequately treated with these medications. We suggest that mirtazapine is a useful drug in this context and its efficacy has been described in case studies. Mirtazapine acts on noradrenergic, serotonergic, histaminergic, and muscarinic receptors to produce antidepressant, anxiolytic, antiemetic, sedative, and appetite-stimulating effects. Mirtazapine is not associated with an independent increased risk of birth defects. Further investigation of mirtazapine as a treatment for HG holds promise to expand treatment options for women suffering from HG.

    The present guidelines were compiled by a multidisciplinary international panel of individuals with interest and expertise in postoperative nausea and vomiting (PONV) under the auspices of The Society of Ambulatory Anesthesia. The panel critically evaluated the current medical literature on PONV to provide an evidence-based reference tool for the management of adults and children who are undergoing surgery and are at increased risk for PONV. In brief, these guidelines identify risk factors for PONV in adults and children; recommend approaches for reducing baseline risks for PONV; identify the most effective antiemetic monotherapy and combination therapy regimens for PONV prophylaxis; recommend approaches for treatment of PONV when it occurs; and provide an algorithm for the management of individuals at increased risk for PONV.

    The antiemetic effect of Pyrimetin in dogs whole-body irradiated with gamma rays at a dose of 500 R, administered per os, intramuscularly, and subcutaneously, immediately before the exposure and after it in the course of the initial symptoms of radiation sickness was studied. A decreased emesis occurred after per os administration of Pyrimetin immediately before whole-body irradiation of the dogs. After the intramuscular application before whole-body irradiation two dogs vomitted, and in the case of the intramuscular administration after whole-body irradiation one dog vomitted. The subcutaneous application of Pyrimetin to dogs before whole-body irradiation and also after it produced only a 30% therapeutic effect. (author)

    Klivinyi, Christoph; Bornemann-Cimenti, Helmar

    2018-01-01

    Long QT syndrome is a cardiac repolarization disorder and is associated with an increased risk of torsades de pointes. The acquired form is most often attributable to administration of specific medications and/or electrolyte imbalance. This review provides insights into the risk for QT prolongation associated with drugs frequently used in the treatment of chronic pain. In the field of pain medicine all the major drug classes (i.e. NSAIDs, opioids, anticonvulsive and antidepressant drugs, cannabinoids, muscle relaxants) contain agents that increase the risk of QT prolongation. Other substances, not used in the treatment of pain, such as proton pump inhibitors, antiemetics, and diuretics are also associated with long QT syndrome. When the possible benefits of therapy outweigh the associated risks, slow dose titration and electrocardiography monitoring are recommended.

    2018-04-01

    Thalidomide was initially synthesised in 1954 and marketed as a sedative and antiemetic for morning sickness. It was withdrawn in 1961 due to the realisation that it was teratogenic with over 10 000 children born with congenital abnormalities. Since then it has been used for treatment of dermatological and oncological conditions, including myeloma. In 1994, it was found to have a potent antiangiogenic effect via downregulation of vascular endothelial growth factor (VEGF). This has led to its use in gastrointestinal bleeding, as vascular abnormalities such as angiodysplasia have been found to have elevated VEGF levels. This article will review the current evidence of the use of thalidomide in bleeding associated with gastrointestinal vascular malformations, including angiodysplasia, gastric cancer and radiation-induced proctitis.

    Although most cases of acute gastroenteritis require minimal medical intervention, severe dehydration and hypoglycemia may develop in cases of prolonged vomiting and diarrhea. The mainstay of treatment for mild-to-moderately dehydrated patients with acute gastroenteritis should be oral rehydration solution. Antiemetics allow for improved tolerance of oral rehydration solution, and, when used appropriately, can decrease the need for intravenous fluids and hospitalization. This issue reviews the common etiologies of acute gastroenteritis, discusses more-severe conditions that should be considered in the differential diagnosis, and provides evidence-based recommendations for management of acute gastroenteritis in patients with mild-to-moderate dehydration, severe dehydration, and hypoglycemia.

    Sculco, Peter K; Pagnano, Mark W

    2015-04-01

    Rapid recovery after total joint arthroplasty requires patients to get ahead and stay ahead or the four impediments to early rehabilitation and discharge: volume depletion, blood loss, pain, and nausea. Adequate volume resuscitation starts before entering the operating room and focuses on intravenous fluids rather than red blood cell transfusion. Tranexamic acid limits blood loss and reduces the need for most other blood management systems. Rapid recovery pain management focuses on minimizing parenteral opioids. A short-acting spinal with a peri-articular local anesthetic injection is reliable, reproducible, and safe. Patients at risk for post-operative nausea are treated with anti-emetic medications and perioperative dexamethasone. These interventions reflect a transition from the sick-patient model to the well-patient model and make rapid recovery joint arthroplasty a reality in 2015. Copyright © 2015 Elsevier Inc.

    2001-05-01

    A case of chronic idiopathic intestinal pseudo-obstruction in an English bulldog is described. The dog was presented with chronic weight loss and vomiting. An intestinal obstruction was suspected based on clinical and radiological findings. A diagnosis of chronic idiopathic intestinal pseudo-obstruction was made on the basis of full thickness intestinal biopsies. The dog was refractory to any antiemetic therapy. Necropsy revealed marked atrophy and fibrosis of the tunica muscularis, together with a mononuclear cell infiltrate extending from the duodenum to the colon. This case was presented with clinical findings consistent with visceral myopathy in humans--namely, atony and dilatation of the whole gut--but the histological findings resembled sclerosis limited to the gastrointestinal tract.

    It is suggested to use metoclopramide (reglan) which is introduced in a dose of 10 ml 10 min before the study intramuscularly at radio X-ray examination of the stomach and duodenum. Peroral application of the drug is not effective. The authors' experience is based on the drug application in 19 healthy persons and 89 patients with the diseases of stomach and duodenum. In patients with gastric ulcer reglan helped in the detection of the niche symptom. The use of the drug facilitated visualization of the pylorus in the case of its organic stenosis. In patients with ulcer of the duodenal bulb after introduction of reglan a better contrasting of the intestine was observed which promoted to the niche detection. An antiemetic property of reglan which can be used in patients, who do not tolerate barium suspension is also pointed out

    To compare the safety and efficacy of a pharmacist-managed patient-controlled analgesia (PCA) service with physician/midlevel provider-managed (standard) PCA services in postsurgical patients. This was a multicenter, retrospective cohort study performed at 3 major hospitals in the Detroit, Michigan, metropolitan area. Postsurgical patients from October 2012 to December 2013 were included. The primary outcome compared the pain area under the curve adjusted for time on PCA (AUC/T) of patients receiving pharmacist-managed PCA services vs. standard care, up to 72 hours after initiation of PCA. Secondary outcomes included initial opioid selection, programmed PCA settings, duration of PCA use, frequency of adjunct analgesia utilization, and frequency of breakthrough analgesia utilization. Safety outcomes were assessed as a composite safety endpoint and individually. Total pain AUC/T scores did not differ between the pharmacist-managed and standard-managed groups (3.25 vs. 3.25, respectively; P = 0.98). Adjunct pain medications were given with similar frequency in the 2 groups; however, significantly fewer patients required breakthrough pain medication in the pharmacist-managed group (11% vs. 36%, respectively; P patients requiring antiemetic use (46% vs. 32%; P = 0.04). A pharmacist-managed PCA service provided no difference in pain control compared to standard management. The requirement for breakthrough analgesia was decreased in the pharmacist group, while the need for antiemetic use was increased. Further research should be conducted to evaluate different PCA management strategies. © 2016 World Institute of Pain.

    There is no research regarding the appropriate antiemetic agents for female patients, especially those receiving moderately emetogenic chemotherapy (MEC). We evaluated the antiemetic efficacy of a combination of 5-HT₃ receptor with/without aprepitant in patients with gynecological cancer treated with the TC (paclitaxel and carboplatin) regimen of MEC. We enrolled 38 patients diagnosed with gynecologic cancer and scheduled to receive the TC regimen. The patients were randomly assigned to receive a 5-HT₃ receptor antagonist, either palonosetron in the first cycle followed by granisetron in the second cycle or vice versa. In the third cycle, all patients received a combination of the 5-HT₃ receptor and dexamethasone with/without aprepitant. When three drugs were administered, palonosetron consistently produced an equivalent complete response (CR) rate to granisetron in the acute phase (89.5% vs. 86.8%, p=0.87) and delayed phase (60.5% vs. 65.8%, p=0.79). With regard to the change in dietary intake, palonosetron exhibited similar efficacy to granisetron in the acute phase (92.1% vs. 89.4%, p=0.19) and delayed phase (65.7% vs. 68.4%, p=0.14). However, in the delayed phase, the addition of aprepitant therapy with a 5-HT₃ receptor antagonist and dexamethasone produced a higher CR rate than a 5-HT₃ receptor antagonist with dexamethasone (93.3% vs. 47.8%, pcontrol therapy of a 5-HT₃ receptor antagonist, and dexamethasone in gynecological cancer patients treated with the TC regimen.

    Full Text Available The herbal medicine rikkunshito has the potential to improve chemotherapy-induced nausea and vomiting (CINV by stimulating ghrelin secretion. We aimed to evaluate the efficacy and safety of rikkunshito in preventing CINV for patients with lung cancer. Two separate prospective, randomized, phase II parallel design studies were conducted in patients with lung cancer. Fifty-eight and sixty-two patients scheduled to receive highly emetogenic chemotherapy (HEC and moderately emetogenic chemotherapy (MEC, respectively, were randomized 1:1 to receive either standard antiemetic therapy in accordance with international guidelines (S group or standard antiemetic therapy plus oral rikkunshito (R group. The primary endpoint was overall complete response (CR—that is, no emesis and rescue medication in the first 120 h post-chemotherapy. Secondary endpoints included CR in the acute (0–24 h and delayed (>24–120 h phases and safety. Fifty-seven patients (S group, 28; R group, 29 receiving HEC and sixty-two patients (S group, 30; R group, 32 receiving MEC with comparable characteristics were evaluated. The CR rates were similar across the S and R groups for the HEC study in the overall (67.9% vs. 62.1%, acute (96.4% vs. 89.6%, and delayed (67.9% vs. 62.1% phases, respectively, and for the MEC study in the overall (83.3% vs. 84.4%, acute (100% vs. 100%, and delayed (83.3% vs. 84.4% phases, respectively. No severe adverse events were observed. Although rikkunshito was well tolerated, it did not demonstrate an additional preventative effect against CINV in lung cancer patients receiving HEC or MEC.Clinical Trial Registry Information: This study is registered with the University Hospital Medical Information Network (UMIN Clinical Trial Registry1, identification numbers UMIN 000014239 and UMIN 000014240.

    Full Text Available Abstract It is commonly claimed that the nausea and vomiting accompanying cytotoxic chemotherapy have a negative impact on health-related quality of life. While this may seem self-evident, until a few years ago there was little empirical data demonstrating that the failure to control postchemotherapy emesis affects aspects of quality of life. In spite of their limitations, several observational studies showed that nausea and vomiting associated with chemotherapy induced a decrease in health-related quality of life with respect to patients without nausea and vomiting. This has also been demonstrated after the adjustment for health-related quality of life before chemotherapy that is an important prognostic factor of chemotherapy-induced nausea and vomiting. Furthermore, one study suggests that the optimal time of assessment of quality of life to evaluate the impact of chemotherapy-induced nausea and vomiting is day 4 if a 3-day recall period is used or day 8 when the recall period is 7 days. In double-blind studies the efficacy, tolerability and impact on quality of life of the 5-HT3 receptor antagonists was superior with respect to metoclopramide, alizapride and prochlorperazine. Similar results have been achieved with the combination of ondansetron with dexamethasone, the standard treatment for the prevention of acute emesis induced by moderately emetogenic chemotherapy, with respect to the metoclopramide plus dexamethasone combination. Instead, in another double-blind study, in patients submitted to moderately emetogenic chemotherapy, a 5-HT3 antagonist did not seem to significantly increase complete protection from delayed emesis and the patients' quality of life with respect to dexamethasone alone. In conclusion, the evaluation of quality of life in randomized trials comparing different antiemetic drugs for the prevention of chemotherapy-induced nausea and vomiting can add important information useful for the choice of the optimal antiemetic

    Full Text Available Background: Gabapentin is an antiepileptic drug. Its antiemetic effect is demonstrated in chemotherapy-induced acute and delayed onset of nausea and vomiting in breast cancer patients. Aim: To evaluate the antiemetic effect of gabapentin on incidence and severity of postoperative nausea and vomiting in laparoscopic cholecystectomy. Settings and Design: Double-blind, randomized, placebo-controlled study. Materials and Methods: Two hundred and fifty patients of ASA physical status I and II, scheduled for laparoscopic cholecystectomy were randomly assigned into two equal groups to receive 600 mg gabapentin or matching placebo two hours before surgery. Standard anaesthesia technique was used. Fentanyl was used as rescue postoperative analgesic. Ondansetron 4 mg was used intravenously as rescue medication for emesis. The total number of patients who had nausea or vomiting, and its severity and total fentanyl consumption in the first 24 hours were recorded. Statistical Analysis: "Z test" was used to test the significance of severity of post-operative nausea and vomiting between groups. Fentanyl consumed in each group (Mean±SD within 24 hrs was compared using student t test. P value< 0.05 was considered significant. Results: There were no demographic difference between the two groups. Incidence of post-operative nausea and vomiting within 24 hrs after laparoscopic cholecystectomy was significantly lower in gabapentin group (46/125 than in the placebo group (75/125 (37.8% vs 60%; P =0.04. There was a significantly decreased fentanyl consumption in gabapentin group (221.2±92.4 µg as compared to placebo group (505.9±82.0 µg; P =0.01. Conclusion: Gabapentin effectively suppresses nausea and vomiting in laparoscopic cholecystectomy and post-operative rescue analgesic requirement.

    Full Text Available AIM: To compare the efficacy of ketoprofen and pethidine for peri-operative analgesia and post-operative nausea and vomiting in children undergoing vitreoretinal surgery and surgery for retinal detachment. MATERIAL AND METHODS: Children aged 7 to 16 years and ASA I status, undergoing vitreo-retinal surgery were randomly allocated to receive either ketoprofen 2mg/kg or pethidine 1mg/kg intravenously for peri-operative analgesia. In all patients, general anaesthesia was induced with thiopentone and intubation was facilitated with vecuronium bromide and maintained with 33% oxygen in nitrous oxide and isoflurane. Intra-operative and post-operative monitoring was done by an observer blinded to the technique. Intra-operative rescue analgesia was used if heart rate and/or blood pressure increased by 25% from pre-incision values. Post-operative pain and episodes of nausea and vomiting were evaluated at recovery (0 hour, 2, 6 and 24 hours intervals. Standard rescue analgesia and anti-emetic agents were administered if required. RESULTS: Eighty-six children were enrolled in the study. Forty-four received ketoprofen while 42 received pethidine. Intra-operative analgesia was comparable in both the groups and no significant difference was found in the requirement of intra-operative rescue analgesia, as well. Postoperatively 6/44 (13.6% children in ketoprofen group had pain at recovery compared to 17/42 (40.4% in pethidine group. Pain at 2, 6 and 24 hours, and postoperative analgesic requirement were not significantly different among the two groups. Post-operative nausea, vomiting, and antiemetic requirement were significantly less in the ketoprofen group at all time intervals. CONCLUSION: Ketoprofen is a satisfactory alternative analgesic to pethidine for vitreoretinal surgery and results in a lower incidence of postoperative nausea and vomiting.

    This randomized, double-blind study evaluated the efficacy of metoclopramide administered at the completion of surgery as an antiemetic agent in pediatric patients undergoing ambulatory strabismus surgery; 126 unpremedicated ASA Physical Status 1 and 2 children ranging in age from 2 to 18 yr served as subjects. All received general anesthesia with halothane, N2O, and O2; tracheal intubation was facilitated with intravenous (iv) atracurium 0.5 mg/kg. Intravenous atropine 0.02 mg/kg and lactated Ringer's solution with 5% dextrose equivalent to 4 h of maintenance fluids were administered during surgery. Neither opioids nor droperidol were given intraoperatively. At the completion of surgery, residual muscle paralysis was reversed with atropine 0.02 mg/kg (maximum dose 1.0 mg) and neostigmine 0.07 mg/kg (maximum dose 5.0 mg), and the stomach was decompressed prior to tracheal extubation. After the patient had been transferred to the postanesthesia recovery room (PARR) either metoclopramide 0.15 mg/kg or normal saline was administered intravenously to the children over a 1-min period. A research associate monitored the children for the incidence of post-operative vomiting and the time required for each child to meet discharge criteria from Short Stay Recovery Unit (SSRU). If a child vomited more than three times in both the PARR and SSRU, the vomiting was construed to be severe and the patient was offered further antiemetic treatment with iv droperidol 70 micrograms/kg. The incidence of postoperative vomiting in the metoclopramide group was 37% versus 59% in the placebo group (P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

    Nausea and/or vomiting (N/V) are frequent side effects of opioid drugs. These are of major concerns to patients and caregivers and only few studies have focused on their economical costs. This is a prospective, nonproduct-related, activity-based evaluation of personnel and material costs of opioid-related N/V among inpatients. Data were obtained from surgical, general medicine, and palliative care wards at 16 German hospitals of different size, healthcare mandate, and ownership. According to predefined criteria, of 462 documented N/V events, 340 were diagnosed as opioid related. Elicited activities and pharmacological interventions for N/V episodes followed local standards. Both materials used and the time engaged to treat patients with N/V were documented on an "ad hoc" activity recording form. The total cost of an opioid-related N/V episode was calculated based on standard wages of the involved personnel and standard costs of the inherent materials used. Mean staff tenure time for handling an episode of N/V was 26.2 ± 19.8 minutes (nausea 16.9 ± 28.7 minutes; nausea + vomiting: 33.4 ± 26.8 minutes). In the German context, this corresponds to average personnel costs of €18.06 ± 13.64. Material cost contributes to another €13.49 ±13.38 of costs mainly depending on acquisition costs of antiemetic drugs. N/V showed to have impact on workload of nurses and (to lesser extent) physicians and economic burden of €31 ± 22 for each N/V episode. In view of these results, the potential costs of strategies to minimize the incidence of N/V (use of antiemetics and/or the use of new analgesics) should be outweighed against the incurred costs of N/V.

    Domperidone is thought to accelerate gastric emptying via D2 receptor antagonism at the gastro-oesophageal and gastro-duodenal junctions. Listed in the BNF as a prokinetic anti-emetic, it has been used in video capsule endoscopy (VCE) to accelerate capsule delivery to the small intestine. We audited VCEs performed at UHCW from 2011, when as standard practice, domperidone was given pre-VCE, to 2012, after its discontinuation due to doubts about its effectiveness. Thirty-one patients received oral domperidone 20 mg pre-VCE. Thirty-three patients underwent VCE without domperidone pre-treatment. After 2 h, if the capsule remained intra-gastric, gastroscopy-assisted duodenal delivery was performed. Data was analysed using Mann-Whitney testing. Median oro-duodenal transit was 13 and 30 min in the untreated and domperidone groups, respectively (p = 0.01). Median oro-caecal transit was 242 and 267 min in the untreated and domperidone groups, respectively (p = 0.02). No difference in duodenal-caecal transit was seen (p = 0.60). Six percent of untreated and 13% of domperidone VCEs required gastroscopy-assisted duodenal capsule delivery (p = 0.65). Unexpectedly domperidone delayed VCE gastric transit. Most studies on domperidone prokinetic effects have been in diabetic gastroparesis, demonstrating that domperidone can achieve good symptomatic relief, but with mixed results for gastric emptying. Our study suggests that any antiemetic effects of domperidone are not mediated through accelerated gastric transit.

    Chemotherapy-induced nausea and vomiting (CINV) is a major concern for cancer patients and, if uncontrolled, can seriously compromise quality of life (QOL) and other treatment outcomes. Because of the expense of antiemetic medications used to prevent CINV (particularly oral medications filled through Medicare Part D), disparities in their use may exist. We used 2006-2012 SEER-Medicare data to evaluate the use of neurokinin-1 receptor antagonists (NK1s), a potent class of antiemetics, among black and white women initiating highly emetogenic chemotherapy for the treatment of early-stage breast cancer. We used modified Poisson regression to assess the relationship between race and (1) any NK1 use, (2) oral NK1 (aprepitant) use, and (3) intravenous NK1 (fosaprepitant) use. We report adjusted risk ratios (aRR) and 95 % confidence intervals (CI). The study included 1130 women. We observed racial disparities in use of any NK1 (aRR: 0.68, 95 % CI 0.51-0.91) and in use of oral aprepitant specifically (aRR: 0.54, 95 % CI 0.35-0.83). We did not observe disparities in intravenous fosaprepitant use. After controlling for variables related to socioeconomic status, disparities in NK1 and aprepitant use were reduced but not eliminated. We found racial disparities in women's use of oral NK1s for the prevention of CINV. These disparities may be partly explained by racial differences in socioeconomic status, which may translate into differential ability to afford the medication.

    Postoperative nausea (PON) is a common complication of anesthesia and surgery. Antiemetic medication for higher-risk patients may reduce but does not reliably prevent PON. We examined aromatherapy as a treatment for patients experiencing PON after ambulatory surgery. Our primary hypothesis was that in comparison with inhaling a placebo, PON will be reduced significantly by aromatherapy with (1) essential oil of ginger, (2) a blend of essential oils of ginger, spearmint, peppermint, and cardamom, or (3) isopropyl alcohol. Our secondary hypothesis was that the effectiveness of aromatherapy will depend upon the agent used. A randomized trial of aromatherapy with patients who reported nausea in the postanesthesia care unit was conducted at one ambulatory surgical center. Eligibility criteria were adult, able to give consent, and no history of coagulation problems or allergy to the aromatherapy agents. Before surgery, demographic and risk factors were collected. Patients with a nausea level of 1 to 3 on a verbal descriptive scale (0-3) received a gauze pad saturated with a randomly chosen aromatherapy agent and were told to inhale deeply 3 times; nausea (0-3) was then measured again in 5 minutes. Prophylactic and postnausea antiemetics were given as ordered by physicians or as requested by the patient. A total of 1151 subjects were screened for inclusion; 303 subjects reporting nausea were enrolled (26.3%), and 301 meeting protocol were analyzed (26.2%). The change in nausea level was significant for the blend (P aromatherapy was also significantly reduced with ginger or blend aromatherapy versus saline (P = 0.002 and P aromatherapy would be effective as a treatment for PON was supported. On the basis of our results, future research further evaluating aromatherapy is warranted. Aromatherapy is promising as an inexpensive, noninvasive treatment for PON that can be administered and controlled by patients as needed.

    Full Text Available BackgroundBone and soft tissue sarcomas are commonly treated with consecutive-day chemotherapy regimens consisting of multiple anticancer agents. Chemotherapy-induced nausea and vomiting (CINV is a serious adverse effect of these regimens and may result in decreased energy intake during chemotherapy. Decreased energy intake may lead to undernutrition and may cause adverse effects on patient quality of life and survival.MethodsPatients with bone and soft tissue sarcomas who received consecutive-day chemotherapy were retrospectively evaluated. CINV and dietary energy intake were assessed, as well as the occurrences of hiccups and constipation during chemotherapy.ResultsA total of 13 patients, 10 males and 3 females, with a total 16 chemotherapy courses were included in the study. All patients received antiemetic prophylaxis. The CINV control rate, defined as no emesis and no rescue therapy, gradually decreased from chemotherapy day 1 (94% to day 5 (75%. Four patients experienced emesis, two of whom had been treated with a cisplatin-containing regimen. Decreased dietary energy intake was possibly associated with CINV during chemotherapy. Anorexia was grade 2 except for one case of grade 3. The incidences of hiccups and constipation were high on days 3–5.ConclusionAntiemetic prophylaxis treatment did not prevent emesis due to consecutive-day chemotherapy, especially with cisplatin-containing regimens, in patients with bone and soft-tissue tumors. Dietary energy intake decreased during chemotherapy, and this appeared to be associated with CINV. In addition, the incidence of hiccups and constipation increased during the course of consecutive-day chemotherapy regimens. Although these results are based on a small number of patients, it may be important to observe nutritional status during chemotherapy, as this may reflect a patient’s general condition. Nutritional counseling might be useful in supporting nutritional status in patients undergoing

    AbstractBackgroundIntravenous fluid is recommended in international guidelines to improve patient post-operative symptoms, particularly nausea and vomiting. The optimum fluid regimen has not been established. This prospective, randomized, blinded study was designed to determine if administration of equivolumes of a colloid (hydroxyethyl starch 130\\/0.4) reduced post operative nausea and vomiting in healthy volunteers undergoing ambulatory gynecologic laparoscopy surgery compared to a crystalloid solution (Hartmann’s Solution).Methods120 patients were randomized to receive intravenous colloid (N = 60) or crystalloid (N = 60) intra-operatively. The volume of fluid administered was calculated at 1.5 ml.kg-1 per hour of fasting. Patients were interviewed to assess nausea, vomiting, anti-emetic use, dizziness, sore throat, headache and subjective general well being at 30 minutes and 2, 24 and 48 hours post operatively. Pulmonary function testing was performed on a subgroup.ResultsAt 2 hours the proportion of patients experiencing nausea (38.2 % vs 17.9%, P = 0.03) and the mean nausea score were increased in the colloid compared to crystalloid group respectively (1.49 ± 0.3 vs 0.68 ± 0.2, P = 0.028). The incidence of vomiting and anti-emetic usage was low and did not differ between the groups. Sore throat, dizziness, headache and general well being were not different between the groups. A comparable reduction on post-operative FVC and FEV-1 and PEFR was observed in both groups.ConclusionsIntra-operative administration of colloid increased the incidence of early postoperative nausea and has no advantage over crystalloid for symptom control after gynaecological laparoscopic surgery.

    Full Text Available Background and Aims: Post-operative nausea and vomiting (PONV is one of the most common complications in patients undergoing gynaecological surgeries under spinal anaesthesia (SA. Palonosetron has the unique property of controlling 'delayed chemotherapy-induced nausea and vomiting' when compared to older serotonin antagonists. This study compared the effectiveness of palonosetron with a combination of ramosetron and dexamethasone in preventing PONV. Methods: Sixty patients undergoing gynaecological surgeries under SA were randomly allocated into two groups of thirty each,to receive either a combination of 0.3 mg of ramosetron and 8 mg of dexamethasone intravenously (IV (Group RD or 0.075 mg of palonosetron IV (Group P. The incidence of PONV, number of complete responders (no nausea, vomiting or use of rescue anti-emetics and severity of nausea were evaluated during intra- and post-operative period. Results: The incidence of complete responders during intraoperative period was 80.0% in Group RD and 76.7% in Group P (P = 0.074 whereas postoperatively at 0–2 h and 2–6 h, it was 73.3% and 83.3% in Group RD respectively as compared to 46.6% and 56.6% in Group P respectively (P = 0.016 and P= 0.024. The incidence of PONV during 24 h of post-operative period was 30.00% in Group RD as compared to 60.00% in Group P (P = 0.0195. Nausea severity score and use of rescue anti-emetics did not vary between the groups. Conclusion: Combination of ramosetron and dexamethasone is more effective than palonosetron alone in preventing PONV in patients undergoing gynaecological surgeries under SA.

    Full Text Available Background: Post-operative nausea and vomiting is one of the most common and distressing complications after anesthesia and surgery. It may lead to serious post-operative complications. Ramosetron is a newer 5-HT3 receptor antagonist and has more potent and longer duration of antiemetic effects compared to first generation 5HT3 receptor antagonists. The purpose of this study was to compare the efficacy of Ramosetron for the prevention of post-operative nausea and vomiting with that of Ondansetron in patients undergoing abdominal surgeries under general anesthesia. Methods: In this randomized, double-blind study, 60 patients, 18-60 years of both genders falling under ASA I-II category scheduled for abdominal surgery were included. Group I received I.V ramosetron 0.3 mg while group II received I.V Ondansetron 4 mg at the time of extubation. The standard general anesthetic technique was used throughout. Postoperatively the incidences of nausea, vomiting, and safety assessments were performed at 1, 2, 6, and 24 h during the first 24 h after surgery. Results: There were no differences between groups with respect to patient demographics. The percentage of patients who had complete response (no PONV, and no need for another rescue antiemetic from 0 to 24 h after anesthesia was 56% with ramosetron and 33% with ondansetron. The corresponding rates at 1, 2, 6, and 24 h after anesthesia were 76% and 63%, 76% and 50%, 100 and 83%, 100 and 93%, respectively. Safety profiles of the two drugs were comparable, as no clinically serious adverse effects caused by study drugs were observed in either of the groups. Conclusion: Our study concludes that prophylactic therapy with ramosetron is highly efficacious than ondansetron in preventing PONV in patients undergoing abdominal surgery under general anesthesia.

    Effective analgesia after midline laparotomy surgery is essential for enhanced recovery programs. We compared three types of continuous abdominal wall block for analgesia after midline laparotomy for gynaecological oncology surgery. We conducted a single-centre, double-blind randomised controlled trial. Ninety-four patients were randomised into three groups to receive two days of programmed intermittent boluses of ropivacaine (18 ml 0.5% ropivacaine every four hours) via either a transversus abdominis plane (TAP) catheter, posterior rectus sheath (PRS) catheter, or a subcutaneous (SC) catheter. All groups received patient-controlled analgesia with morphine, and regular paracetamol and non-steroidal anti-inflammatory medication. Measured outcomes included analgesic and antiemetic usage and visual analog scores for pain, nausea, vomiting, and satisfaction. Eighty-eight patients were analysed (29 SC, 29 PRS and 30 TAP). No differences in the primary outcome were found (median milligrams morphine usage on day two SC 28, PRS 25, TAP 21, P =0.371). There were differences in secondary outcomes. Compared with the SC group, the TAP group required less morphine in recovery (0 mg versus 6 mg, P =0.01) and reported less severe pain on day one (visual analog scores 36.3 mm versus SC 55 mm, P =0.04). The TAP group used fewer doses of tropisetron on day one compared with the PRS group (8 versus 21, P =0.016). Programmed intermittent boluses of ropivacaine delivered via PRS, TAP and SC catheters can be provided safely to patients undergoing midline laparotomy surgery. Initially TAP catheters appear superior, reducing early opioid and antiemetic requirements and severe pain, but these advantages are lost by day two.

    Hyperemesis gravidarum (HG) is the most severe form of nausea and vomiting of pregnancy which can have potentially dangerous complications if untreated. Its treatment is basically supportive as the condition itself is self-limiting. The aim of our study was to evaluate maternal characteristics in patients with HG including risk factors and treatment outcome with respect to improvement in Pregnancy Unique Quantification of Emesis (PUQE) scores, number of doses of antiemetics used, weight gain during treatment and duration of intravenous fluid therapy A cross-sectional study where all women admitted to B.P. Koirala Institute of Health Sciences with a diagnosis of HG during a period of one year were studied for different maternal characteristics. The severity of disease was quantified using Modified PUQE score and the various treatment outcomes considered. The admission for hyperemesis gravidarum (n=81, including 13 readmissions) was 10.64% of total early pregnancy admissions (n = 735).The condition was more common in nulliparous patients (56%) at a mean period of gestation of 8.93 ± 2.33 wks. Most patients suffered from moderate to severe disease at presentation, mean PUQE scores being 12.29 ± 1.59. The median number of doses of intravenous antiemetics used was three (IQR 3-6), median weight gain was one kg (IQR 0-1 kg), median duration of intravenous fluid therapy was 24 hrs (IQR 24-48 hrs) and mean length of hospital stay was 3.2 ± 1.48 days. Hyperemesis is one of the common causes of hospitalization in early pregnancy. Treatment has favourable outcome with early recovery.

    Full Text Available Background: Postoperative nausea and vomiting (PONV remains a signifi cant problem in the surgical population. Many researchers have demonstrated signifi cant reductions in institutional PONV when risk screening and antiemetic prophylaxis protocols are implemented. These protocols have not been universally adopted. Our adoption and implementation led to signifi cant reductions in PONV. The challenge is to sustain these reductions over time. Methods: A retrospective cohort chart review of consecutive surgical patients (n = 1002 during the period encompassing October through November of 2016, the sustainability group (G16. Descriptive statistics were used to compare G16 with the implementation group (G14 in regard to demographic data, and Z-score and Chi-square (χ2 statistics were utilized to determine levels of signifi cance. Correlations were calculated to determine levels of compliance to the protocol and the incidence of PONV. Results: A significant (P = 0.0007 reduction in PONV incidence was identified as 8.5% (85/1002 in G16 compared to 13.4% (134/997 achieved in G14. Overall compliance with the targeted prophylaxis protocol was 87.2% (G16, 874/1002, a significant (P = 0.0001 improvement compared to 79% (G14, 788/997. A 61.1% (11/18 incidence of PONV in laparoscopic gastric bypass patients was identifi ed in the G16 group. Conclusions: Initial reductions in PONV were not only sustained but significantly improved. Preoperative risk assessment for PONV, risk stratification, and fidelity to anti-emetic prophylaxis protocols reduce the incidence of PONV in the post-anesthesia care unit. High-risk patients require three or more interventions to obtain acceptable reductions in PONV. Laparoscopic gastric bypass patients remain a high-risk group requiring aggressive multimodal prophylaxis beyond their Apfel simplifi ed risk score.

    Dexamethasone has been reported to reduce postoperative symptoms after different surgical procedures. We evaluated the efficacy of preoperative dexamethasone in ameliorating postoperative nausea and vomiting (PONV), and pain after mastectomy. In this prospective, double-blind, placebo-controlled study, 70 patients scheduled for mastectomy with axillary lymph node dissection were analyzed after randomization to treatment with 8 mg intravenous dexamethasone (n = 35) or placebo (n = 35). All patients underwent standardized procedures for general anesthesia and surgery. Episodes of PONV and pain score were recorded on a visual analogue scale. Analgesic and antiemetic requirements were also recorded. Demographic and medical variables were similar between groups. The incidence of PONV was lower in the dexamethasone group at the early postoperative evaluation (28.6% vs. 60%; p = 0.02) and at 6 h (17.2% vs. 45.8%; p = 0.03). More patients in the placebo group required additional antiemetic medication (21 vs. 8; p = 0.01). Dexamethasone treatment significantly reduced postoperative pain just after surgery (VAS score, 4.54 ± 1.55 vs. 5.83 ± 2.00; p = 0.004), at 6 h (3.03 ± 1.20 vs. 4.17 ± 1.24; p < 0.0005) and at 12 h (2.09 ± 0.85 vs. 2.54 ± 0.98; p = 0.04). Analgesics were required in more patients of the control group (21 vs. 10; p = 0.008). There were no adverse events, morbidity or mortality. Preoperative intravenous dexamethasone (8 mg) can significantly reduce the incidence of PONV and pain in patients undergoing mastectomy with axillary dissection for breast cancer. NCT01116713

    To compare analgesia and adverse effects during oral morphine and oxycodone and transdermal fentanyl and buprenorphine administration in cancer patients with pain. Cancer patients treated at home and in outpatient clinics with severe pain (numerical rating scale score 6-10) fail to respond to non-opioids and/or weak opioids. All patients were randomized to either morphine, oxycodone, fentanyl or buprenorphine and divided into subgroups with predominant neuropathic and nociceptive pain component. Doses of opioids were titrated to satisfactory analgesia and acceptable adverse effects intensity. Patients were assessed at baseline and followed for 28 days. In all patient groups, immediate-release oral morphine was the rescue analgesic and lactulose 10 mL twice daily was the prophylaxis of constipation; no antiemetics were used as prophylaxis. A total of 62 patients participated and 53 patients completed the study. Good analgesia was obtained for all 4 opioids, for both nociceptive and neuropathic pain. The use of co-analgesics was greater in patients with neuropathic pain. Morphine treatment was associated with less negative impact of pain on ability to walk, work and activity (trend) according to Brief Pain Inventory-Short Form scores and less consumption of rescue morphine. The most common adverse effects included nausea and drowsiness, which increased at the beginning of the treatment and gradually decreased over the days to come. Appetite, well-being, anxiety, depression, and fatigue improved. There was no constipation (the Bowel Function Index scores were within normal range) during the treatment with all opioids. No changes were seen for constipation, vomiting and dyspnea. All opioids were effective and well-tolerated. Morphine was the most effective in the improvement in some of the Brief Pain Inventory-Short Form items regarding negative impact of pain on patients' daily activities. Prophylaxis of constipation was effective; antiemetics may be considered for

    Background: Hyperemesis gravidarum (HG) is the most severe form of nausea and vomiting of pregnancy which can have potentially dangerous complications if untreated. Its treatment is basically supportive as the condition itself is self-limiting. The aim of our study was to evaluate maternal characteristics in patients with HG including risk factors and treatment outcome with respect to improvement in Pregnancy Unique Quantification of Emesis (PUQE) scores, number of doses of antiemetics used, weight gain during treatment and duration of intravenous fluid therapy Methods: A cross-sectional study where all women admitted to B.P. Koirala Institute of Health Sciences with a diagnosis of HG during a period of one year were studied for different maternal characteristics. The severity of disease was quantified using Modified PUQE score and the various treatment outcomes considered. Results: The admission for hyperemesis gravidarum (n=81, including 13 re-admissions) was 10.64 percentage of total early pregnancy admissions (n=735). The condition was more common in nulliparous patients (56 percentage) at a mean period of gestation of 8.93±2.33wks. Most patients suffered from moderate to severe disease at presentation, mean PUQE scores being 12.29±1.59. The median number of doses of intravenous antiemetics used was three (IQR 3-6), median weight gain was one kg (IQR 0-1kg), median duration of intravenous fluid therapy was 24hrs (IQR 24-48hrs) and mean length of hospital stay was 3.2±1.48 days. Conclusions: Hyperemesis is one of the common causes of hospitalization in early pregnancy. Treatment has favourable outcome with early recovery. (author)

    This study is a prospective randomized clinical trial comparing the efficacy and complication of anti-emetic drugs for prevention of nausea and vomiting after radiotherapy which has moderate emetogenic potential. The aim of this study was to investigate whether the anti-emetic efficacy at ondansetron(Zofran) 8 mg bid dose (Group O) is better than the efficacy of metoclopramide 5 mg tid dose (Group M) in patients undergoing fractionated radiotherapy to the abdominal region. Study entry was restricted to those patients who met the following eligibility criteria: histologically confirmed malignant disease; no distant metastasis; performance status of not more than ECOG grade 2; no previous chemotherapy and radiotherapy. Between March 1997 and February 1998, 60 patients enrolled in this study. All patients signed a written statement of informed consent prior to enrollment. Blinding was maintained by dosing identical number of tables including one dose of matching placebo for Group O. The extent of nausea, appetite loss, and the number of emetic episodes were recorded everyday using diary card. The mean score of nausea, appetite loss and the mean number of emetic episodes were obtained in a weekly interval. Prescription error occurred in one patient. And diary cards have not returned in 3 patients due to premature refusal of treatment. Card from one patient was excluded from the analysis because she had a history of treatment for neurosis. As a result, the analysis consisted of 55 patients. Patient characteristics and radiotherapy characteristics were similar except mean age was 52.9{+-} 11.2 in group M, 46.5{+-}9.6 in group O. The difference of age was statistically significant. The mean score of nausea, appetite loss and emetic episodes in a weekly interval was higher in group M than O. In group M, the symptoms were most significant at 5th week. In a panel data analysis using mixed procedure, treatment group was only significant factor detecting the difference of

    Cannabinoid hyperemesis syndrome is a clinical disorder that has become more prevalent with increasing use of cannabis and synthetic cannabinoids, and which is difficult to treat. Standard antiemetics commonly fail to alleviate the severe nausea and vomiting characteristic of the syndrome. Curiously, cannabinoid hyperemesis syndrome patients often report dramatic relief of symptoms with hot showers and baths, and topical capsaicin. In this review, we detail the pharmacokinetics and pharmacodynamics of capsaicin and explore possible mechanisms for its beneficial effect, including activation of transient receptor potential vanilloid 1 and neurohumoral regulation. Putative mechanisms responsible for the benefit of hot water hydrotherapy are also investigated. An extensive search of PubMed, OpenGrey, and Google Scholar from inception to April 2017 was performed to identify known and theoretical thermoregulatory mechanisms associated with the endocannabinoid system. The searches resulted in 2417 articles. These articles were screened for relevant mechanisms behind capsaicin and heat activation having potential antiemetic effects. References from the selected articles were also hand-searched. A total of 137 articles were considered relevant and included. Capsaicin: Topical capsaicin is primarily used for treatment of neuropathic pain, but it has also been used successfully in some 20 cases of cannabinoid hyperemesis syndrome. The pharmacokinetics and pharmacodynamics of capsaicin as a transient receptor potential vanilloid 1 agonist may explain this effect. Topical capsaicin has a longer half-life than oral administration, thus its potential duration of benefit is longer. Capsaicin and transient receptor potential vanilloid 1: Topical capsaicin binds and activates the transient receptor potential vanilloid 1 receptor, triggering influx of calcium and sodium, as well as release of inflammatory neuropeptides leading to transient burning, stinging, and itching. This elicits

    This is an updated version of the original Cochrane review published in Issue 10, 2010, on droperidol for the treatment of nausea and vomiting in palliative care patients. Nausea and vomiting are common symptoms in patients with terminal illness and can be very unpleasant and distressing. There are several different types of antiemetic treatments that can be used to control these symptoms. Droperidol is an antipsychotic drug and has been used and studied as an antiemetic in the management of postoperative and chemotherapy nausea and vomiting. To evaluate the efficacy and adverse events (both minor and serious) associated with the use of droperidol for the treatment of nausea and vomiting in palliative care patients. We searched electronic databases including CENTRAL, MEDLINE (1950-), EMBASE (1980-), CINAHL (1981-) and AMED (1985-), using relevant search terms and synonyms. The basic search strategy was ("droperidol" OR "butyrophenone") AND ("nausea" OR "vomiting"), modified for each database. We updated the search on 2 December 2009. We performed updated searches of MEDLINE, EMBASE, CENTRAL and AMED 2009 to 2013 on 19 November 2013 and of CINAHL on 20 November 2013. We also searched trial registers (metaRegister of controlled trials (www.controlled-trials.com/mrct), clinicaltrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (http://apps.who.int/trialsearch/)) on 22 November 2013, using the keyword "droperidol". Randomised controlled trials (RCTs) of droperidol for the treatment of nausea or vomiting, or both, in adults receiving palliative care or suffering from an incurable progressive medical condition. We judged the potential relevance of studies based on their titles and abstracts, and obtained studies that we anticipated might meet the inclusion criteria. Two review authors independently reviewed the abstracts for the initial review and four review authors reviewed the abstracts for the update to assess

    Patients frequently remain in the hospital after bariatric surgery due to pain, nausea, and inability to tolerate oral intake. Enhanced recovery after surgery (ERAS) concepts address these perioperative complications and therefore improve length of stay for bariatric surgery patients. To determine if ERAS concepts increase the proportion of patients discharged on postoperative day 1. Secondary objectives included mean length of stay, perioperative opioid use, emergency department visits, and readmissions. A large metropolitan university tertiary hospital. A quantitative before and after study was conducted for patients undergoing bariatric surgical patients. Data were collected surrounding length of stay, perioperative opioid consumption, antiemetic therapy requirements postoperatively, multimodal analgesia compliance, emergency department visits, and hospital readmission rates. Wilcoxon rank-sum and χ 2 test were used to compare continuous and categorical variables, respectively. A secondary analysis was performed using Aligned Rank Transformation and Cochran-Mantel-Haenszel χ 2 tests to account for an increase in sleeve gastrectomies in the intervention group. The 2 groups had clinically similar baseline characteristics. Comparison group (N = 366) and ERAS group (N = 715) patients underwent a primary bariatric surgery procedure. There was an increase in the number of patients undergoing a laparoscopic sleeve gastrectomy in the intervention group. After accounting for this increase, the percentage of patients discharged on postoperative day 1 was unchanged (79.8% non-ERAS versus 83.1% ERAS, P = .52). ERAS length of stay was statistically significantly lower for gastric bypass (P<.001) and robotic gastric bypass (P = .01). Perioperative opioid consumption was reduced (41.0 versus 16.2 morphine equivalents, P<0.001), and fewer ERAS patients required postoperative antiemetics (68.8% versus 46.2%, P<.001). Emergency department visits at 7 days were reduced (6

    Full Text Available Abstract Background Chemotherapy induced nausea and vomiting (CINV remains a major problem that seriously impairs the quality of life (QoL in cancer patients receiving chemotherapy regimens. Complementary medicines, including homeopathy, are used by many patients with cancer, usually alongside with conventional treatment. A randomized, placebo-controlled Phase III study was conducted to evaluate the efficacy of a complex homeopathic medicine, Cocculine, in the control of CINV in non-metastatic breast cancer patients treated by standard chemotherapy regimens. Methods Chemotherapy-naïve patients with non-metastatic breast cancer scheduled to receive 6 cycles of chemotherapy including at least three initial cycles of FAC 50, FEC 100 or TAC were randomized to receive standard anti-emetic treatment plus either a complex homeopathic remedy (Cocculine, registered in France for treatment of nausea and travel sickness or the matching placebo (NCT00409071 clinicaltrials.gov. The primary endpoint was nausea score measured after the 1st chemotherapy course using the FLIE questionnaire (Functional Living Index for Emesis with 5-day recall.

    Antiemetic guidelines recommend co-administration of targeted prophylactic medications inhibiting molecular pathways involved in emesis. NEPA is a fixed oral combination of a new NK 1 receptor antagonist (RA), netupitant (NETU 300 mg), and palonosetron (PALO 0.50 mg), a pharmacologically distinct 5-HT 3 RA. NEPA showed superior prevention of chemotherapy-induced nausea and vomiting (CINV) compared with oral PALO in a single chemotherapy cycle; maintenance of efficacy/safety over continuing cycles is the objective of this study. This study is a multinational, double-blind study comparing a single oral dose of NEPA vs oral PALO in chemotherapy-naïve patients receiving anthracycline/cyclophosphamide-based chemotherapy along with dexamethasone 12 mg (NEPA) or 20 mg (PALO) on day 1. The primary efficacy endpoint was delayed (25-120 h) complete response (CR: no emesis, no rescue medication) in cycle 1. Sustained efficacy was evaluated during the multicycle extension by calculating the proportion of patients with overall (0-120 h) CR in cycles 2-4 and by assessing the probability of sustained CR over multiple cycles. Of 1455 patients randomized, 1286 (88 %) participated in the multiple-cycle extension for a total of 5969 cycles; 76 % completed ≥4 cycles. The proportion of patients with an overall CR was significantly greater for NEPA than oral PALO for cycles 1-4 (74.3 vs 66.6 %, 80.3 vs 66.7 %, 83.8 vs 70.3 %, and 83.8 vs 74.6 %, respectively; p ≤ 0.001 each cycle). The cumulative percentage of patients with a sustained CR over all 4 cycles was also greater for NEPA (p < 0.0001). NEPA was well tolerated over cycles. NEPA, a convenient, guideline-consistent, fixed antiemetic combination is effective and safe over multiple cycles of chemotherapy.

    This study aims to assess the feasibility of acupuncture and a Pericardium 6 (PC6) wristband as an add-on intervention of antiemetic medication for the prevention of postoperative nausea and vomiting (PONV) in patients undergoing elective laparoscopic colorectal cancer resection. A total of 60 participants who are scheduled to undergo elective laparoscopic resection of colorectal cancer will be recruited. An enhanced recovery after surgery protocol using standardised antiemetic medication will be provided for all participants. Participants will be equally randomised into acupuncture plus PC6 wristband (Acupuncture), PC6 wristband alone (Wristband), or no acupuncture or wristband (Control) groups using computer-generated random numbers concealed in opaque, sealed, sequentially numbered envelopes. For the acupuncture combined with PC6 wristband group, the embedded auricular acupuncture technique for preoperative anxiolysis and up to three sessions of acupuncture treatments with manual and electrical stimulation within 48 hours after surgery will be provided by qualified Korean medicine doctors. The PC6 wristband will be applied in the Acupuncture and Wristband groups, beginning 1 hour before surgery and lasting 48 hours postoperatively. The primary outcome will be the number of participants who experience moderate or severe nausea, defined as nausea at least 4 out of 10 on a severity numeric rating scale or vomiting at 24 hours after surgery. Secondary outcomes, including symptom severity, participant global assessments and satisfaction, quality of life, physiological recovery, use of medication and length of hospital stay, will be assessed. Adverse events and postoperative complications will be measured for 1 month after surgery. All participants will provide written informed consent. The study has been approved by the institutional review board (IRB). This pilot trial will inform a full-scale randomised trial of acupuncture combined with PC6 stimulation

    Purpose: To assess, in a prospective, observational study, the safety and efficacy of the addition of the neurokinin-1-receptor antagonist (NK1-RA) aprepitant to concomitant radiochemotherapy, for the prophylaxis of radiation therapy–induced nausea and vomiting. Patients and Methods: This prospective observational study compared the antiemetic efficacy of an NK1-RA (aprepitant), a 5-hydroxytryptamine-RA, and dexamethasone (aprepitant regimen) versus a 5-hydroxytryptamine-RA and dexamethasone (control regimen) in patients receiving concomitant radiochemotherapy with cisplatin at the Department of Radiation Oncology, University Hospital Halle (Saale), Germany. The primary endpoint was complete response in the overall phase, defined as no vomiting and no use of rescue therapy in this period. Results: Fifty-nine patients treated with concomitant radiochemotherapy with cisplatin were included in this study. Thirty-one patients received the aprepitant regimen and 29 the control regimen. The overall complete response rates for cycles 1 and 2 were 75.9% and 64.5% for the aprepitant group and 60.7% and 54.2% for the control group, respectively. Although a 15.2% absolute difference was reached in cycle 1, a statistical significance was not detected (P=.22). Furthermore maximum nausea was 1.58 ± 1.91 in the control group and 0.73 ± 1.79 in the aprepitant group (P=.084); for the head-and-neck subset, 2.23 ± 2.13 in the control group and 0.64 ± 1.77 in the aprepitant group, respectively (P=.03). Conclusion: This is the first study of an NK1-RA–containing antiemetic prophylaxis regimen in patients receiving concomitant radiochemotherapy. Although the primary endpoint was not obtained, the absolute difference of 10% in efficacy was reached, which is defined as clinically meaningful for patients by international guidelines groups. Randomized phase 3 studies are necessary to further define the potential role of an NK1-RA in this setting.

    After vaginal surgery, oral and parenteral narcotics are used commonly for pain relief, and their use may exacerbate the incidence of sedation, nausea, and vomiting, which ultimately delays convalescence. Previous studies have demonstrated that rectal analgesia after surgery results in lower pain scores and less intravenous morphine consumption. Belladonna and opium rectal suppositories may be used to relieve pain and minimize side effects; however, their efficacy has not been confirmed. We aimed to evaluate the use of belladonna and opium suppositories for pain reduction in vaginal surgery. A prospective, randomized, double-blind, placebo-controlled trial that used belladonna and opium suppositories after inpatient or outpatient vaginal surgery was conducted. Vaginal surgery was defined as (1) vaginal hysterectomy with uterosacral ligament suspension or (2) posthysterectomy prolapse repair that included uterosacral ligament suspension and/or colporrhaphy. Belladonna and opium 16A (16.2/60 mg) or placebo suppositories were administered rectally immediately after surgery and every 8 hours for a total of 3 doses. Patient-reported pain data were collected with the use of a visual analog scale (at 2, 4, 12, and 20 hours postoperatively. Opiate use was measured and converted into parenteral morphine equivalents. The primary outcome was pain, and secondary outcomes included pain medication, antiemetic medication, and a quality of recovery questionnaire. Adverse effects were surveyed at 24 hours and 7 days. Concomitant procedures for urinary incontinence or pelvic organ prolapse did not preclude enrollment.

Current antiemetic guidelines recommend that the neurokinin-1 receptor (NK-1R antagonist aprepitant should be used as part of a combination regimen with dexamethasone and a serotonin receptor antagonist for the prevention of CINV in patients receiving highly emetogenic chemotherapy (HEC. Fosaprepitant is a water-soluble N-phosphoryl derivative of aprepitant that, when infused, is rapidly metabolized back to an active aprepitant. The existing literature in PubMed about fosaprepitant was screened and selected in order to address the emerging data from two randomized clinical trials evaluating the efficacy and safety of a single-dose fosaprepitant regimen. These phase III trials demonstrated that fosaprepitant given as a single intravenous dose of 150 mg was either noninferior to the conventional 3-day aprepitant or significantly superior to placebo for the prevention of acute and delayed CINV in patients receiving high-dose cisplatin. In both trials, fosaprepitant was well tolerated although more frequent infusion-site adverse events were observed with fosaprepitant. The new dosage regimen of fosaprepitant, therefore, would be an option for CINV control in patients receiving cisplatin-based chemotherapy. The clinical efficacy is consistent with the findings from a time-on-target, positron-emission tomography study evaluating the NK-1R occupancy in the central nervous system (CNS over 5 days after a single-dose infusion of 150 mg fosaprepitant in healthy participants. The single-dose regimen is capable of blocking more than 90% of the NK-1Rs in the CNS for at least 48 hours after infusion, which is sufficient

Patients and methods: Cancer patients treated at home and in outpatient clinics with severe pain (numerical rating scale score 6–10 fail to respond to non-opioids and/or weak opioids. All patients were randomized to either morphine, oxycodone, fentanyl or buprenorphine and divided into subgroups with predominant neuropathic and nociceptive pain component. Doses of opioids were titrated to satisfactory analgesia and acceptable adverse effects intensity. Patients were assessed at baseline and followed for 28 days. In all patient groups, immediate-release oral morphine was the rescue analgesic and lactulose 10 mL twice daily was the prophylaxis of constipation; no antiemetics were used as prophylaxis. Results: A total of 62 patients participated and 53 patients completed the study. Good analgesia was obtained for all 4 opioids, for both nociceptive and neuropathic pain. The use of co-analgesics was greater in patients with neuropathic pain. Morphine treatment was associated with less negative impact of pain on ability to walk, work and activity (trend according to Brief Pain Inventory-Short Form scores and less consumption of rescue morphine. The most common adverse effects included nausea and drowsiness

    Early feeding is well tolerated in patients undergoing caesarean section under general or regional anaesthesia. Intrathecal morphine is effective for postoperative analgesia but can induce nausea and vomiting which may hamper feeding. This study assessed prospectively the effects of intrathecal morphine on early feeding in patients undergoing caesarean section. After ethical committee approval, 66 consenting women scheduled for caesarean section were randomized to receive intrathecal morphine 0.1 mg (group M, n=32) or not ("control group", group C, n=34) at the time of intrathecal anaesthesia performed with a 3 ml mixture containing 8.6 mg bupivacaine, 64 microg clonidine and 4.3 microg sufentanil. Standard antiemetic prophylaxis (5 mg dexamethasone + 2 mg tropisetron) was administered intravenously in all patients after umbilical cord clamping. Standardized multimodal analgesia was initiated postoperatively with 1 g of paracetamol and 30 mg of ketorolac given every 6 hours. Analgesia was evaluated by a numeric rating scale (NRS) at 4 hours intervals and 10 mg of oral morphine was administered if the NRS score exceeded 3. All patients received a protein enriched solution, 8 hours after caesarean section and were allowed to eat solid food on postoperative day 1. Nausea and vomiting episodes, gas and/or stools emission, itching, NRS score and morphine consumption were recorded on the first, second and fourth postoperative hour and then every 4 hours during 48 hours. Nausea was significantly more frequent and persisted longer in group M. Vomiting occurred equally in both groups and stopped after feeding. Gas and/or stools emission appeared within 48 hours postoperatively in 72 and 77 % of patients in group M and group C respectively. Oral morphine consumption was significantly lower in group M (1.9+/-4 vs 6.5+/-7.3mg, p=0.006). When compared to group C, NRS were also lower in group M from the second to the 20th postoperative hour. Itching was observed more frequently

Differences in postoperative pain, incidence of patient-controlled analgesia (PCA-related adverse effects, and risk factors for the need for rescue analgesics for 48 hours postsurgery in young (age 20–39 years and elderly (age ≥70 years patients were evaluated. Although there were no significant differences in postoperative pain intensity between the two groups until 6 hours postsurgery, younger patients experienced greater postoperative pain intensity compared with older patients 6–48 hours postsurgery. While younger patients exhibited greater incidence of numbness, motor weakness, and discontinuation of PCA postsurgery, elderly patients exhibited greater incidence of hypotension, nausea/vomiting, rescue analgesia, and antiemetic administration. Upon multivariate analysis, low fentanyl dosage and history of smoking were found to be associated with an increased need for rescue analgesia among younger patients, while physical status classification III/IV and thoracic surgery were associated with a decreased need for rescue analgesia among the elderly. Discontinuation of PCA was more frequent among younger patients than the elderly (18.5% vs 13.5%, P=0.001. Reasons for discontinuation of PCA among young and elderly patients, respectively, were nausea and vomiting (6.8% vs 26.6%, numbness or motor weakness (67.8% vs 11.5%, urinary retention (7.4% vs 8.7%, dizziness (2.2% vs 5.2%, and hypotension (3.1% vs 20.3%.

    Full Text Available Motion sickness occurs under a variety of circumstances and is common in the general population. It is usually associated with changes in gastric motility, and hypothermia, which are argued to be surrogate markers for nausea; there are also reports that respiratory function is affected. As laboratory rodents are incapable of vomiting, Suncus murinus was used to model motion sickness and to investigate changes in gastric myoelectric activity (GMA and temperature homeostasis using radiotelemetry, whilst also simultaneously investigating changes in respiratory function using whole body plethysmography. The anti-emetic potential of the highly selective histamine H1 receptor antagonists, mepyramine (brain penetrant, and cetirizine (non-brain penetrant, along with the muscarinic receptor antagonist, scopolamine, were investigated in the present study. On isolated ileal segments from Suncus murinus, both mepyramine and cetirizine non-competitively antagonized the contractile action of histamine with pKb values of 7.5 and 8.4, respectively; scopolamine competitively antagonized the contractile action of acetylcholine with pA2 of 9.5. In responding animals, motion (1 Hz, 4 cm horizontal displacement, 10 min increased the percentage of the power of bradygastria, and decreased the percentage power of normogastria whilst also causing hypothermia. Animals also exhibited an increase in respiratory rate and a reduction in tidal volume. Mepyramine (50 mg/kg, i.p. and scopolamine (10 mg/kg, i.p., but not cetirizine (10 mg/kg, i.p., significantly antagonized motion-induced emesis but did not reverse the motion-induced disruptions of GMA, or hypothermia, or effects on respiration. Burst analysis of plethysmographic-derived waveforms showed mepyramine also had increased the inter-retch+vomit frequency, and emetic episode duration. Immunohistochemistry demonstrated that motion alone did not induce c-fos expression in the brain. Paradoxically, mepyramine increased c

    Full Text Available Abstract Background When patients are asked what they find most anxiety provoking about having surgery, the top concerns almost always include postoperative nausea and vomiting (PONV. Only until recently have there been any published recommendations, mostly derived from expert opinion, as to which regimens to use once a patient develops PONV. The goal of this study was to assess the responses to a written survey to address the following questions: 1 If no prophylaxis is administered to an ambulatory patient, what agent do anesthesiologists use for treatment of PONV in the ambulatory Post-Anesthesia Care Unit (PACU?; 2 Do anesthesiologists use non-pharmacologic interventions for PONV treatment?; and 3 If a PONV prophylaxis agent is administered during the anesthetic, do anesthesiologists choose an antiemetic in a different class for treatment? Methods A questionnaire with five short hypothetical clinical vignettes was mailed to 300 randomly selected USA anesthesiologists. The types of pharmacological and nonpharmacological interventions for PONV treatment were analyzed. Results The questionnaire was completed by 106 anesthesiologists (38% response rate, who reported that on average 52% of their practice was ambulatory. If a patient develops PONV and received no prophylaxis, 67% (95% CI, 62% – 79% of anesthesiologists reported they would administer a 5-HT3-antagonist as first choice for treatment, with metoclopramide and dexamethasone being the next two most common choices. 65% (95% CI, 55% – 74% of anesthesiologists reported they would also use non-pharmacologic interventions to treat PONV in the PACU, with an IV fluid bolus or nasal cannula oxygen being the most common. When PONV prophylaxis was given during the anesthetic, the preferred PONV treatment choice changed. Whereas 3%–7% of anesthesiologists would repeat dose metoclopramide, dexamethasone, or droperidol, 26% (95% confidence intervals, 18% – 36% of practitioners would re

    Full Text Available Abstract Background Several in vitro studies have looked at the effect of medicinal plant extracts against Helicobacter pylori (H. pylori. Regardless of the popular use of Byrsonima crassa (B. crassa as antiemetic, diuretic, febrifuge, to treat diarrhea, gastritis and ulcers, there is no data on its effects against H. pylori. In this study, we evaluated the anti-H. pylori of B. crassa leaves extracts and its effects on reactive oxygen/nitrogen intermediates induction by murine peritoneal macrophages. Methods The minimal inhibitory concentration (MIC was determined by broth microdilution method and the production of hydrogen peroxide (H2O2 and nitric oxide (NO by the horseradish peroxidase-dependent oxidation of phenol red and Griess reaction, respectively. Results The methanolic (MeOH and chloroformic (CHCl3 extracts inhibit, in vitro, the growth of H. pylori with MIC value of 1024 μg/ml. The MeOH extract induced the production H2O2 and NO, but CHCl3 extract only NO. Conclusion Based in our results, B. crassa can be considered a source of compounds with anti-H. pylori activity, but its use should be done with caution in treatment of the gastritis and peptic ulcers, since the reactive oxygen/nitrogen intermediates are involved in the pathogenesis of gastric mucosal injury induced by ulcerogenic agents and H. pylori infections.

    Indigenous knowledge of medicinal plants was recorded during summer 2004, in 22 villages of Chagharzai valley, District Buner. The study revealed 141 plant species belonging to 120 genera and 26 families are being used as medicine. The local people know the prospect and nature of the plant utilization, through personal experiences and ancestral prescriptions. The study also revealed that old aged people particularly women posses strong folk love of medicinal plants in comparison to young people. It was concluded that some plants are used singly while many other are used in combination. Similarly few plant species are used for the treatment of a specific disease, while several other have multiple uses. The plants were mainly used as stomachic, anti-allergic, antineuralgia, vermifuge, narcotic, laxative, anti jaundice, emollient, hypnotic, diuretic, digestive, demulcent, carminative, astringent, aphrodisiac, anti-spasmodic, anti-emetic, anti-diabetic, anthelmentic, anodyne and alterative. The present investigation will help in the preservation of indigenous knowledge of the local people, which is depleting day by day. (author)

    This article reports on the clinical practice guidelines developed by a multidisciplinary group working on the indications and uses of the various available treatment options for relieving intestinal obstruction or its symptoms in patients with peritoneal carcinomatosis. These guidelines are based on a literature review and expert opinion. The recommended strategy involves a clinical and radiological evaluation, of which CT of the abdomen is a crucial component. The results, together with an analysis of the prognostic criteria, are used to determine whether surgery or stenting is the best option. In most patients, however, neither option is feasible, and the main emphasis, therefore, is on the role and administration of various symptomatic medications such as glucocorticoids, antiemetic agents, analgesics, and antisecretory agents (anticholinergic drugs, somatostatin analogues, and proton-pump inhibitors). Nasogastric tube feeding is no longer used routinely and should instead be discussed on a case-by-case basis. Recent studies have confirmed the efficacy of somatostatin analogues in relieving obstruction-related symptoms such as nausea, vomiting, and pain. However, the absence of a marketing license and the high cost of these drugs limit their use as the first-line treatment, except in highly selected patients (early recurrence). When these medications fail to alleviate the symptoms of obstruction, venting gastrostomy should be considered promptly. Rehydration is needed for virtually every patient. Parenteral nutrition and pain management should be adjusted according to the patient needs and guidelines. Copyright © 2014 U.S. Cancer Pain Relief Committee. Published by Elsevier Inc.

    Full Text Available Day surgery, coming to and leaving the hospital on the same day as surgery as well as ambulatory surgery, leaving hospital within twenty-three hours is increasingly being adopted. There are several potential benefits associated with the avoidance of in-hospital care. Early discharge demands a rapid recovery and low incidence and intensity of surgery and anaesthesia related side-effects; such as pain, nausea and fatigue. Patients must be fit enough and symptom intensity so low that self-care is feasible in order to secure quality of care. Preventive multi-modal analgesia has become the gold standard. Administering paracetamol, NSIADs prior to start of surgery and decreasing the noxious influx by the use of local anaesthetics by peripheral block or infiltration in surgical field prior to incision and at wound closure in combination with intra-operative fast acting opioid analgesics, e.g., remifentanil, have become standard of care. Single preoperative 0.1 mg/kg dose dexamethasone has a combined action, anti-emetic and provides enhanced analgesia. Additional α-2-agonists and/or gabapentin or pregabalin may be used in addition to facilitate the pain management if patients are at risk for more pronounced pain. Paracetamol, NSAIDs and rescue oral opioid is the basic concept for self-care during the first 3–5 days after common day/ambulatory surgical procedures.

    Full Text Available Rikkunshito is a popular Japanese traditional medicine that is prescribed in Japan to treat various gastrointestinal tract disorders. In a double-blind controlled study, rikkunshito significantly ameliorated dysmotility-like dyspepsia and brought about a generalized improvement in upper gastric symptoms such as nausea and anorexia when compared with a control group. Several studies in rats have shown enhanced gastric emptying and a protective effect on gastric mucosa injury with rikkunshito administration. In addition, rikkunshito in combination with an anti-emetic drug is effective against anorexia and vomiting that occur as adverse reactions to chemotherapy in patients with advanced breast cancer. However, the mechanism by which rikkunshito alleviates gastrointestinal disorders induced by anticancer agents remains unclear. It has recently been shown that rikkunshito ameliorates cisplatin-induced anorexia by mediating an increase in the circulating ghrelin concentration. Moreover, Fujitsuka et al. found that decreased contractions of the antrum and duodenum in rats treated with a selective serotonin reuptake inhibitor were reversed by rikkunshito via enhancement of the circulating ghrelin concentration. These findings show that rikkunshito may be useful for treatment of anorexia and may provide a new strategy for improvement of upper gastrointestinal dysfunction.

    Sorafenib followed by fractionated radiotherapy (RT) has been shown to decrease the phagocytic and candidacidal activities of antifungal agents due to radiosensitization. Moreover, sorafenib has been shown to suppress the immune system, thereby increasing the risk for candida colonization and infection. In this study, we present the 2 hepatocellular carcinoma (HCC) patients suffered from epigastric distress caused by esophageal candidiasis who received sorafenib plus RT. Two patients who had received sorafenib and RT for HCC with bone metastasis presented with hiccups, gastric ulcer, epigastric distress, anorexia, heart burn, and fatigue. Empiric antiemetic agents, antacids, and pain killers were ineffective at relieving symptoms. Panendoscopy revealed diffuse white lesions in the esophagus. Candida esophagitis was suspected. Results of periodic acid-Schiff staining were diagnostic of candidiasis. Oral fluconazole (150 mg) twice daily and proton-pump inhibitors were prescribed. At 2-weak follow-up, esophagitis had resolved and both patients were free of gastrointestinal symptoms. Physicians should be aware that sorafenib combined with RT may induce an immunosuppressive state in patients with HCC, thereby increasing their risk of developing esophagitis due to candida species.

    To identify factors associated with prolonged Hyperemesis Gravidarum (HG). About 395 women completed a survey regarding pre-existing conditions, treatments and outcomes. Responses were compared using two-sided t-tests or the F-test. Participants with prolonged HG are slightly younger and weigh more. Pre-existing factors associated with prolonged HG include allergies and a restrictive diet. Prolonged HG is associated with hematemesis, dizziness, fainting and antiemetic treatment. Following pregnancy, those with prolonged HG reported more posttraumatic stress, motion sickness, muscle weakness and infants with irritability, severe colic and growth restriction. Multiple pre-existing conditions and poor maternal and infant outcomes were associated with prolonged HG. The most significant condition prior to pregnancy was allergies suggesting a possible autoimmune component affecting duration of HG. In addition, the most significant lifestyle choice linked to prolonged HG was a restrictive diet. Future research is needed to determine whether a change in diet prior to pregnancy may lead to a shorter duration of HG and its associated outcomes.

    Full Text Available Renealmia alpinia (Zingiberaceae, a medicinal plant of tropical rainforests, is used to treat snakebites and other injuries and also as a febrifuge, analgesic, antiemetic, antiulcer, and anticonvulsant. The dichloromethane extract of R. alpinia leaves showed potent inhibition of human monoamine oxidases- (MAOs- A and B. Phytochemical studies yielded six known compounds, including pinostrobin 1, 4′-methyl ether sakuranetin 2, sakuranetin 3, pinostrobin chalcone 4, yashabushidiol A 5, and desmethoxyyangonin 6. Compound 6 displayed about 30-fold higher affinity for MAO-B than MAO-A, with Ki values of 31 and 922 nM, respectively. Kinetic analysis of inhibition and equilibrium-dialysis dissociation assay of the enzyme-inhibitor complex showed reversible binding of desmethoxyyangonin 6 with MAO-A and MAO-B. The binding interactions of compound 6 in the active site of the MAO-A and MAO-B isoenzymes, investigated through molecular modeling algorithms, confirmed preferential binding of desmethoxyyangonin 6 with MAO-B compared to MAO-A. Selective reversible inhibitors of MAO-B, like desmethoxyyangonin 6, may have important therapeutic significance for the treatment of neurodegenerative disorders, such as Parkinson’s disease and Alzheimer’s disease.

    Full Text Available Aim — The main focus of the project was to identify whether there is any interaction between Ketotifen Fumarate (antihistamine and domperidone (Antiemetic/dopaminergic antagonist present or not at simulated gastric and intestinal solutions of different pH. Methods — Using Job’s continuous-variation analysis the possible drug-drug interaction was determined at a fixed temperature (37ºC at the studied pH. From Job’s continuous-variation analysis the views of drug-drug interaction at different concentration ratio at all pH (0.4, 1.2, 2.0, 2.8, 6.8, and 7.4 except 6.0 were noted. Results — Data obtained from spectroscopic analysis showed decrease in free-drug concentration of both of the drugs analyzed when they were within the same gastric simulated solution. Conclusion — Concurrent administration of Ketotifen Fumarate and domperidone would result in the formation of a stable complex and this is likely to reduce the the rapeutic activities of both drugs.

    Postoperative nausea and vomiting frequently complicate outpatient anesthesia and surgery. The duration of treatment for this complication must occasionally extend beyond discharge from the hospital. In this study, we evaluated the commonly used anti-emetic promethazine for its efficacy in the post-discharge period. Adult outpatient surgical patients who had excessive postoperative nausea and vomiting in the recovery room, or who were at risk for postoperative nausea and vomiting following discharge were given two promethazine suppositories (25 mg) for home use. All patients were contacted by our recovery room nurses on the first business day after their surgery and questioned as to their use of the suppositories and, if used, their efficacy. We found that 55 percent of patients given promethazine suppositories for home use had nausea and vomiting in the post-discharge period. Of the patients given promethazine, 89 percent used the suppositories. All of these patients reported improvement in their symptoms following use of the suppositories. None reported adverse effects from the promethazine suppositories. In conclusion, we found promethazine suppositories to be an inexpensive and efficacious treatment for nausea and vomiting in adult outpatient surgical patients following discharge from the hospital. Side-effects were minimal, and our patients voiced no complaints about this mode of therapy. We recommend this therapy for treatment of nausea and vomiting after hospital discharge following adult outpatient surgery. PMID:10527366

    The involvement of 5-hydroxytryptamine (5-HT) 5-HT/sub 3/ receptors in the mechanisms of severe emesis evoked by cytotoxic drugs or by total body irradiation have been studied in ferrets. Anti-emetic compounds tested were domperidone (a dopamine antagonist), metoclopramide (a gastric motility stimulant and dopamine antagonist at conventional doses, a 5-HT/sub 3/ receptor antagonist at higher doses) and BRL 24924 (a potent gastric motility stimulant and a 5-HT/sub 3/ receptor antagonist). Domperidone or metoclopramide prevented apomorphine-evoked emesis, whereas BRL 24924 did not. Similar doses of domperidone did not prevent emesis evoked by cis-platin or by total body irradiation, whereas metoclopramide or BRL 24924 greatly reduced or prevented these types of emesis. Metoclopramide and BRL 24924 also prevented emesis evoked by a combination of doxorubicin and cyclophosphamide. These results are discussed in terms of a fundamental role for 5-HT/sub 3/ receptors in the mechanisms mediating severely emetogenic cancer treatment therapies.

    Full Text Available Background Antiemetic guidelines recommend co-administration of agents to maximize the prevention of chemotherapyinduced nausea and vomiting (CINV, however, the control of delayed CINV is still not satisfactory. The purpose of this study was to evaluate the effectiveness and safety of thalidomide in the prevention of CINV. Methods Of 89 patients enrolled, 83 chemotherapy-naïve patients receiving highly emetogenic chemotherapy (cisplatin 70mg/m2 were randomized into two groups: standard therapy group (ondansetron on day 1, metoclopramide and dexamethasone on days one to five and thalidomide group (in addition to standard emesis prevention, patients received oral 100mg thalidomide on days one to five. Patients recorded nausea and vomiting episodes in a diary. The primary end point was the efficacy of thalidomide in controlling vomiting and nausea on days one to five post cisplatin, and the secondary end point was the safety of the thalidomide. Results No significant differences of complete response rates (no emesis, no use of rescue therapy and no nausea were observed between the two groups, while the percentages of patients with complete response of delayed vomiting on day four and day five were higher in the thalidomide group, furthermore, the complete response rate of delayed nausea for thalidomide group and standard therapy group showed significant differences. Thalidomide group showed a similar safety profile as standard emesis prevention group. Conclusion Addition of thalidomide was generally well tolerated and improved prevention of CINV in patients receiving cisplatinbased chemotherapy to some degree, especially for delayed nausea.

    Full Text Available Bernardo Leon Rapoport The Medical Oncology Centre of Rosebank, Johannesburg, South Africa Abstract: Chemotherapy-induced nausea and vomiting (CINV is a debilitating side effect of many cytotoxic chemotherapy regimens. CINV typically manifests during two well-defined time periods (acute and delayed phases. The acute phase is the first 24 hours after chemotherapy and is largely managed with 5-hydroxytryptamine 3 receptor antagonists. The delayed phase, a 5-day at-risk period during which patients are not often in direct contact with their health care provider, remains a significant unmet medical need. Neurokinin-1 (NK-1 receptor antagonists have demonstrated protection against acute and delayed CINV in patients treated with highly emetogenic chemotherapy and moderately emetogenic chemotherapy when used in combination with a 5-hydroxytryptamine 3 receptor antagonist and dexamethasone. Furthermore, recent data indicate that this protection is maintained over multiple treatment cycles. Rolapitant, a selective and long-acting NK-1 receptor antagonist, is approved as oral formulation for the prevention of delayed CINV in adults. This review discusses the differential pharmacology and clinical utility of rolapitant in preventing CINV compared with other NK-1 receptor antagonists.

    Full Text Available CONTEXT AND OBJECTIVE: Nausea and vomiting are major inconveniences for patients undergoing chemotherapy. Despite standard preventive treatment, chemotherapy-induced nausea and vomiting (CINV still occurs in approximately 50% of these patients. In an attempt to optimize this treatment, we evaluated the possible effects of carbamazepine for prevention of CINV.DESIGN AND LOCATION: Prospective nonrandomized open-label phase II study carried out at a Brazilian public oncology service. METHODS: Patients allocated for their first cycle of highly emetogenic chemotherapy were continuously recruited. In addition to standard antiemetic protocol that was made available, they received carbamazepine orally, with staggered doses, from the third day before until the fifth day after chemotherapy. Considering the sparseness of evidence about the efficacy of anticonvulsants for CINV prevention, we used Simon's two-stage design, in which 43 patients should be included unless overall complete prevention was not achieved in 9 out of the first 15 entries. The Functional Living Index-Emesis questionnaire was used to measure the impact on quality of life.RESULTS:None of the ten patients (0% presented overall complete prevention. In three cases, carbamazepine therapy was withdrawn because of somnolence and vomiting before chemotherapy. Seven were able to take the medication for the entire period and none were responsive, so the study was closed. There was no impact on the patients' quality of life.CONCLUSION: Carbamazepine was not effective for prevention of CINV and also had a deleterious side-effect profile in this population.

    Nausea and vomiting are side-effects that are associated with chemo- and radiotherapy. A single-blind study to compare the efficacy and safety of intravenous granisetron (G) with metoclopramide (M) plus dexamethasone (D) in the prophylaxis and control of nausea and emesis in patients undergoing hemi-body irradiation (HBI) was performed. G (3 mg) or M (20 mg) plus D (12 mg) were given intravenously, thirty minutes prior to the start of radiotherapy. Patients were monitored for nausea, vomiting and side-effects. Thirty-five patients were treated, 28 men and 7 women. A total of 21 (60%) patients did not vomit during the first 24 hours after the start of radiotherapy. Both G and M plus D offer safe and effective anti-emetic regimes for the prophylaxis and control of radiotherapy induced nausea and vomiting. However, granisetron was found to be more effective than metoclopramide plus dexamethasone in preventing nausea and vomiting. 101 refs., 40 tabs., 8 figs

    Full Text Available Objective: To study the nutritional status and inflammatory stress levels after gastric cancer patients with chemotherapy received palonosetron and tropisetron. Methods: 94 patients with advanced gastric cancer undergoing FOLFOX4 intravenous chemotherapy in our hospital between May 2014 and March 2016 were selected and randomly divided into observation group (n=47 and control group (n=47 who received palonosetron and tropisetron for chemotherapy anti-emesis respectively. After four cycles of chemotherapy, serum samples were collected from two groups of patients to determine nutritional status, inflammatory reaction and stress reaction indexes. Results: After four cycles of chemotherapy, serum albumin (ALB, prealbumin (PAB, transferrin (TFN, immunoglobulin A (IgA, IgG and IgM content of observation group were significantly higher than those of control group (P<0.05. After four cycles of chemotherapy, serum Keap1 content of observation group was significantly higher than that of control group (P<0.05, while Nrf2, ARE, NQO1, HO-1, interferon-γ (IFN-γ, tumor necrosis factor α (TNF-α, interleukin-4 (IL-4 and IL-10 content were significantly lower than those of control group (P<0.05. Conclusions: Palonosetron has better antiemetic effect than tropisetron for gastric cancer patients with chemotherapy, and after chemotherapy, the nutritional status is better and the inflammatory stress level is lighter.

    In the course of the specific oncologic treatment, there are frequent complications such as nausea and vomiting. The radiation-induced emetic reflex depends on various factors: primary site of radiation, administered dose, fractioning, irradiated volume, the sensory and psychic characteristics of the patient as well as the chemotherapy association. It is known that the afferent path to the so-called center of vomiting is determined by chemical mediators, protuberance receptors of the intracranial pressure and the unleashing chemoreceptor zone. In radiation-induced emesis, the exact mechanism is yet to be determined but it is known that radiation stimulates the production of chemical mediators and serotonin released by enterochromaffin cells that act upon the center of vomiting and vagal nucleus. Most of patients who are exposed to irradiation of their upper and middle hemibody as well as all the patients exposed to whole-body irradiation present with nausea and vomiting. The therapeutical anti-emetic recommendations are based on the neurochemical control of vomiting and the emetogenic effect of radiotherapy. 5HT3 receptor-antagonists are evaluated as effective agents in the control of radiation-induced emesis

    Full Text Available Aim. Efficacy of granisetron and combination of granisetron and dexamethasone was evaluated for prevention of postoperative nausea and vomiting (PONV in children undergoing elective strabismus surgery. Methods. A total of 136 children (1–15 years were included. Children received either granisetron (40 mcg/kg [group G] or combination of granisetron (40 mcg/kg and dexamethasone (150 mcg/kg [group GD]. Intraoperative fentanyl requirement and incidence and severity of oculocardiac reflex were assessed. PONV severity was assessed for first 24 hours and if score was >2, it was treated with metoclopramide. Postoperative analgesia was administered with intravenous fentanyl and ibuprofen. Results. The demographic profile, muscles operated, and fentanyl requirement were comparable. Complete response to PONV in first 24 hours was observed in 75% (51/68 of children in group G and 76.9% (50/65 of children in group GD, which was comparable statistically (p=0.96, Fisher exact test; OR 1.11, 95% CI 0.50, 2.46. Incidence of PONV between 0 and 24 hours was comparable. One child in group G required rescue antiemetic in first 24 hours and none of the children had severe PONV in group GD. There was no significant difference in incidence or severity of oculocardiac reflex. Conclusion. Dexamethasone did not increase efficacy of granisetron for prevention of PONV in elective pediatric strabismus surgery. Registration number of clinical trial was CTRI/2009/091/001000.

    In Europe and the United States, D9-tetrahydrocannabinol(THC, dronabinol), one of the psychoactive constituents of cannabis, has been used for both its anti-emetic and orexigenic effects in cancer patient receiving chemotherapy.However, dronabinol has not yet been launched in the market in Japan.In the future, it is necessary to ascertain the pharmacokinetics of dronabinol in cancer paitient.Therefore, we developed an HPLC procedure using electrochemical detection(ECD)for quan- titation of the concentrations of dronabinol in blood.An eluent of 50mM KH2PO4/CH3CN(9:16)was used as the mobile phase.The column was used the XTerra®RP18, and the voltage of the electrochemical detector in dronabinol was set at 400 mV.As a result, the calibration curve was linear in the range of 10 ng/mL to 100 ng/mL(y=964.85x -3,419, r=0.997).The lower limit of quantification was 0.5 ng/mL(S/N=3).The relative within-runs and between-runs standard deviations for the assay dronabinol were less than 4.7%. The method reported here is superior to previously reported methods in cancer patient.

    Cannabis is not only a widely used illicit drug but also a substance which can be used in pharmacological therapy because of its analgesic, antiemetic, and antispasmodic properties. A very rapid and sensitive method for determination of ∆(9)-tetrahydrocannabinol (THC), the principal active component of cannabis, and two of its phase I metabolites in plasma has been developed and validated. After solid-phase extraction of plasma (0.2 mL), the clean extracts were analyzed by tandem mass spectrometry after a 5-min liquid chromatographic separation. The linear calibration ranges were from 0.05 to 30 ng mL(-1) for THC and 11-nor-∆(9)-carboxy-tetrahydrocannabinol (THC-COOH) and from 0.2 to 30 ng mL(-1) for ∆(9)-(11-OH)-tetrahydrocannabinol (11-OH-THC). Imprecision and inaccuracy were always below 7 and 12 % (expressed as relative standard deviation and relative error), respectively. The method has been successfully applied to determination of the three analytes in plasma obtained from healthy volunteers after oral administration of 20 mg dronabinol.

    New cardiology guidelines recommend antiplatelet therapy for some patients with cardiac stents. Aspirin use is relatively contraindicated during urologic surgery because of increased bleeding risk. We sought to review the outcomes of patients who continued aspirin during robot-assisted radical prostatectomy. Between October 2007 and February 2010, 249 patients underwent robot-assisted radical prostatectomy by a single surgeon. After consultation with the patients' cardiologists, 6 patients had coronary artery stents and continued aspirin perioperatively (Group 1), and 7 patients had coronary artery stents but did not continue aspirin perioperatively (Group 2). The remaining 236 patients had no coronary artery stents and did not require continued aspirin (Group 3). We analyzed our patients' preoperative characteristics, including age, prostate-specific antigen volume, and D'Amico risk, as well as operative time, blood loss, hematocrit changes, transfusion requirements, length of hospital stay, and complications. We found no differences in operative time, estimated blood loss, changes in hematocrit, or length of hospital stay. No patients with any type of cardiac stent required a postoperative blood transfusion or had complications requiring more than simple anti-emetics, analgesics, or electrolyte correction. Nine patients in Group 3 required interventions for significant complications. Larger studies need to be performed to validate these observations.

    There are currently eight groups of drugs for the pharmacotherapy of vertigo, nystagmus, and cerebellar disorders: antiemetics; anti-inflammatories, antimenieres, and antimigraineous medications; antidepressants, anticonvulsants, aminopyridines, and acetyl-DL-leucine ("the eight A's"). In acute unilateral vestibulopathy, corticosteroids improve the recovery of peripheral vestibular function, but there is not sufficient current evidence for a general recommendation. There is also insufficient evidence that 48 or 144 mg/day betahistine has an effect in Ménière's disease. Therefore, higher dosages are currently recommended; in animal studies, it was shown that betahistine increases cochlear blood flow. In vestibular paroxysmia, oxcarbazepine was effective (one yet not randomized controlled trial (RCT)). Aminopyridines are recommended for the treatment of downbeat nystagmus (two RCTs) and episodic ataxia type 2 (EA2, one RCT). There are so far no RCTs on vestibular migraine, so currently no treatment can be recommended. Acetyl-dl-leucine improves cerebellar ataxia (three observational studies); it also accelerates central compensation in an animal model of acute unilateral lesion, but RCTs were negative. There are ongoing RCTs on vestibular paroxysmia with carbamazepine (VESPA), acute unilateral vestibulopathy with betahistine (BETAVEST), vestibular migraine with metoprolol (PROVEMIG), benign paroxysmal positional vertigo with vitamin D (VitD@BPPV), EA2 with 4-aminopyridine versus acetazolamide (EAT-2-TREAT), and cerebellar ataxias with acetyl-DL-leucine (ALCAT). © 2015 New York Academy of Sciences.

On admission, she was dehydrated with remarkably worsening symptoms. Laboratory findings revealed significantly elevated liver enzymes with unknown etiology. Her past medical history showed an admission for nausea and vomiting 3 weeks previously and she was discharged on antiemetics, and esomeprazole for the first time. Due to the predominantly elevated liver enzymes, the clinical pharmacist discussed the possibility of esomeprazole-induced adverse effects and suggested to suspend esomeprazole based on the evidence from literature review. The liver enzymes showed a substantial improvement within days after the discontinuation of the drug; however, a rechallenge was not done since it could have adversely affected the mother or the fetus. Using the Naranjo Adverse Drug Reaction Probability scales, the adverse reaction due to esomeprazole was classified as “probably”.

    Transdermal application can be an alternative drug delivery route for ondansetron, an antiemetic drug. Previous studies found that fatty acids, namely oleic and lauric, were the most effective penetration enhancers. The aim of this study was to investigate the formation of an ion pair between ondansetron and lauric acid as a possible mechanism of its enhancing action. Several techniques were used to reveal the formation of an ion pair complex. Partitioning experiments, where the n-octanol/water coefficient was measured, showed an increase in the distribution coefficient in the presence of the acid, possibly as a result of the formation of more lipophilic ion pairs between the charged molecules of ondansetron and lauric acid. Further evidence of complex formation between ondansetron and lauric acid, was gained from the 13C-nuclear magnetic resonance (13C-NMR) spectra of ondansetron, lauric acid, and their mixture (molar ratio 1:1). The NMR spectra revealed alterations to the magnetic environment of the carbon atoms adjacent to the ionized group, which are the carbonyl group of the acid and the nitrogen of the imidazole ring of ondansetron. This evidence substantiates the theory of ion pair formation. Finally, thermal analysis of the binary mixtures of ondansetron and lauric acid revealed the formation of an additional compound, with different melting point from pure ondansetron and lauric acid, which is thermodynamically favored.

    In patients with motor fluctuations complicating Parkinson's disease (PD), delays in time-to-ON with levodopa are common. This open-label study aimed to assess the effect of apomorphine on time-to-ON in PD patients with morning akinesia. The safety population included 127 enrolled patients, and the full analysis set (FAS) included 88 patients. Patients completed a 7-day levodopa baseline period recording their time-to-ON following each morning dose of levodopa. Patients were titrated to an optimal dose of apomorphine (2-6 mg) while taking trimethobenzamide antiemetic therapy. Apomorphine was injected each morning for a 7-day treatment period and time-to-ON was self-recorded in 5-minute blocks. The primary efficacy variable was time-to-ON in the apomorphine treatment period versus the baseline levodopa period. Secondary assessments included and global impression scales. Safety and tolerability were assessed through adverse events (AEs). Patients receiving apomorphine achieved mean ± standard deviation (SD) time-to-ON 23.72 ± 14.55 minutes, reduced from 60.86 ± 18.11 minutes with levodopa ( P 60 minutes) were more commonly reported with levodopa versus apomorphine (46% vs. 7% of diary entries, respectively). Secondary endpoints supported the primary efficacy findings, with significant improvements from levodopa baseline to apomorphine treatment period (all P morning levodopa dose, and was well tolerated in most patients. After apomorphine treatment, fluctuating patients with morning akinesia experienced rapid and reliable improvement of time-to-ON.

    Full Text Available Background: Copper sulfate ingestion is a relatively popular method for committing suicide in Indian subcontinent. It causes a high mortality rate, and so a growing concern has been raised to identify the severe alarming signs suggestive of poor prognosis and to improve treatment approaches. Case report: A 22-year-old unmarried man working as a painter was found unconscious at his friend residence. The patient developed hypotension, hemorrhagic gastroenteritis with hematemesis and melena, renal and hepatic failure, severe metabolic acidosis and intravascular hemolysis during admission at hospital. His signs were refractory to treatment with fluid replacement therapy, vasoactive drugs, antiemetic drugs, ranitidine, furosemide, methylene blue and 2,3 dimercaptopropane-1-sulphonate. He died six hours post-admission. In post-mortem examinations, there were multiple sub-pleural and sub-epicardial hemorrhages and the gastrointestinal mucosa was congested, hemorrhagic, and greenish blue in color. The liver, on histological examination, showed sub-massive hepatic necrosis. On toxicological analyses, copper sulfate was detected in preserved viscera and results for other heavy metals were negative. Conclusion: Hypotension, cyanosis, uremia and jaundice can be considered as signs of poor prognosis in copper sulfate poisoning. Copper sulfate ingestion is life-threatening due to its deleterious effects on the upper GI, kidneys, liver and blood. Having no time to waste, aggressive treatments should be immediately instituted and signs of poor prognosis should be kept in mind.

    A randomized controlled trial was performed to assess the outcome of early oral postoperative feeding (EOF) compared with traditional oral feeding (TOF) in gynecologic oncology patients undergoing laparotomy with associated intestinal resection. Patients aged 18-75 years, undergoing elective laparotomy, and with preoperative diagnosis of gynecologic malignancy, were eligible. Exclusion criteria included infectious conditions, intestinal obstruction, severe malnutrition, American Society of Anesthesiologists (ASA) score > or =4, and postoperative stay in the intensive care unit lasting >24 h. Patients allocated to EOF received liquid diet in the first postoperative day and then regular diet. Patients received traditional feeding scheme until resolution of postoperative ileus to start liquid diet. The primary end-point of the trial was length of hospital stay. Between January 1st, 2007 and March 15th, 2008, 40 patients were randomized to receive either EOF or TOF. Hospital stay in patients who received EOF (n = 18) was 6.9 days versus 9.1 days in the TOF group (n = 22) (P = 0.022). Requirements for analgesic and antiemetic drugs, intensity of pain, intestinal function recovery, mean levels of postoperative satisfaction, postoperative complications, and quality-of-life scores did not differ between the two groups. Early resumption of oral intake is feasible and safe in gynecologic oncology patients undergoing intestinal resection as part of a planned surgical procedure. Moreover, significant reduction in length of hospital stay was demonstrated.

    Terrorism involving radioactive materials includes improvised nuclear devices, radiation exposure devices, contamination of food sources, radiation dispersal devices, or an attack on a nuclear power plant or a facility/vehicle that houses radioactive materials. Ionizing radiation removes electrons from atoms and changes the valence of the electrons enabling chemical reactions with elements that normally do not occur. Ionizing radiation includes alpha rays, beta rays, gamma rays, and neutron radiation. The effects of radiation consist of stochastic and deterministic effects. Cancer is the typical example of a stochastic effect of radiation. Deterministic effects include acute radiation syndrome (ARS). The hallmarks of ARS are damage to the skin, gastrointestinal tract, hematopoietic tissue, and in severe cases the neurovascular structures. Radiation produces psychological effects in addition to physiological effects. Radioisotopes relevant to terrorism include titrium, americium 241, cesium 137, cobalt 60, iodine 131, plutonium 238, califormium 252, iridium 192, uranium 235, and strontium 90. Medications used for treating a radiation exposure include antiemetics, colony-stimulating factors, antibiotics, electrolytes, potassium iodine, and chelating agents.

    Diarrhea is the second cause of child morbidity and mortality in Morocco after acute respiratory infection. Each child suffers from 4 to 8 episodes of diarrhea per year. The purpose of this study was to evaluate the knowledge as well as diagnostic and therapeutic practices of general practitioners regarding children presenting with diarrhea. Study was based on an epidemiologic survey using a written questionnaire completed by general practitioners in state-run hospitals in the Marrakesh (Tensift El Haouz) region. The anonymous questionnaire containing items on the epidemiological, clinical, laboratory, and therapeutic aspects was distributed in all 5 medical districts in the region. Analysis of reponses concerning therapeutic practices showed heavy reliance on oral rehydration that was prescribed by 98.2% of general practitioners. Dietary analysis was performed by only 24% of practitioners and blood/stool testing was not systematically ordered. Only 3% of practitioners recommended early resumption of feeding. However, data showed excessive use of additional laboratory tests (57.8%) and prescription drugs (48.8%). Overprescription mainly involved antiemetics and anti-diarrheals (77.7%). This study demonstrates an urgent need to develop a strategy to improve the quality of dietary management of diarrhea by general practitioners and rationalize prescription drug use. A continuing medical education program would be useful to increase the awareness of general practitioners and reduce child/infant morbidity and mortality relating to this disease.

    With little scientific evidence to support use of aromatherapy for postoperative nausea and/or vomiting (PONV) symptoms, this study evaluated controlled breathing with peppermint aromatherapy (AR) and controlled breathing alone (CB) for PONV relief. A single blind randomized control trial design was used. On initial PONV complaint, symptomatic subjects received either CB (n = 16) or AR (n = 26) intervention based on randomization at enrollment. A second treatment was repeated at 5 minutes if indicated. Final assessment occurred 10 minutes post initial treatment. Rescue medication was offered for persistent symptoms. Among eligible subjects, PONV incidence was 21.4% (42/196). Gender was the only risk factor contributing to PONV symptoms (P = .0024). Though not statistically significant, CB was more efficacious than AR, 62.5% versus 57.7%, respectively. CB can be initiated without delay as an alternative to prescribed antiemetics. Data also support use of peppermint AR in conjunction with CB for PONV relief. Copyright © 2014 American Society of PeriAnesthesia Nurses. Published by Elsevier Inc. All rights reserved.

    Delayed chemotherapy-induced nausea and vomiting (CINV) remains an important adverse effect of moderately emetogenic chemotherapy not containing anthracyclines and cyclophosphamide (non-AC MEC). In this review, we summarize current literature to update recommendations for delayed CINV prophylaxis after non-AC MEC. We conducted a systematic search in PubMed and conference proceedings from ASCO, ESMO, and MASCC. Included randomized controlled trials (RCTs) aimed to prospectively evaluate the efficacy of two or more antiemetic strategies in the prevention of delayed CINV after the administration of non-AC MEC. At least one of the following endpoints was used: complete response, complete control, no nausea, no vomiting, and/or no use of rescue medication. Our search provided 247 publications. Nine met the predefined criteria. Included RCTs reported outcomes on palonosetron, aprepitant, casopitant, netupitant/palonosetron (NEPA), olanzapine, and megestrol acetate. Superiority of palonosetron over first-generation 5-HT3 receptor antagonists for the prevention of acute and delayed CINV after non-AC MEC has not been proven. The addition of an NK1 receptor antagonist to first-generation 5-HT3 receptor antagonists does not significantly improve the incidence of delayed CINV after non-AC MEC. The efficacy of a single-day regimen of dexamethasone with palonosetron is non-inferior to multiday dexamethasone. NEPA, olanzapine, and megestrol acetate show highly effective complete response (CR) rates.

  12. Delayed Chemotherapy-Induced Nausea and Vomiting: Pathogenesis, Incidence, and Current Management.

    Even when chemotherapy-induced nausea and vomiting (CINV) can be effectively controlled in the acute phase, it may still occur in the delayed phase. Identifying at-risk patients is complex and requires consideration of clinical, personal, demographic, and behavioral factors. Delayed CINV has a significant detrimental effect on patients' daily life and is responsible for significant healthcare resource utilization. Patients who do not experience acute CINV are not necessarily exempt from delayed CINV, and healthcare professionals have been shown to underestimate the incidence of delayed CINV. Failure to protect against CINV during the first cycle of chemotherapy is the most significant independent risk factor for delayed CINV during subsequent cycles. Addition of a neurokinin-1 receptor antagonist to antiemetic prophylactic regimens involving a 5-hydroxytryptamine type 3 receptor antagonist and a corticosteroid helps to ameliorate delayed CINV, particularly vomiting. Netupitant and rolapitant are second-generation neurokinin-1 receptor antagonists that provide effective prophylaxis against delayed chemotherapy-induced vomiting and also have an antinausea benefit. All of the neurokinin-1 receptor antagonists with the exception of rolapitant inhibit or induce cytochrome P450 3A4 (CYP3A4), and a reduced dose of dexamethasone (a CYP3A4 substrate) should be administered with aprepitant or netupitant; by contrast, this is not necessary with rolapitant. Here we review specific challenges associated with delayed CINV, its pathophysiology, epidemiology, treatment, and outcomes relative to acute CINV, and its management within the larger context of overall CINV.

    Chemotherapy-induced nausea and vomiting (CINV) remains an important adverse effect of cancer therapy. The goal of CINV prophylaxis is to reduce the morbidity associated with nausea and vomiting, as well as to preserve quality of life, while maintaining the desired chemotherapy regimen. The US Food and Drug Administration has recently approved new therapies for prevention of CINV, including the neurokinin-1 (NK1) receptor antagonist rolapitant and the fixed-dose combination of the second-generation 5-hydroxytryptamine type 3 receptor antagonist palonosetron with the novel NK1 receptor antagonist netupitant. Alternative agents, like the atypical antipsychotic olanzapine, have also expanded the options available for preventing delayed and refractory CINV. Consensus guidelines for prevention of CINV from several organizations are generally consistent with one another and are updated based on expert review of available clinical trial data. This article will address changes in CINV guidelines over the past 5 years and provide updates on recently approved agents and agents that are expected to be approved, based on published phase III trials. It will also explore other factors affecting optimal CINV control, including the role of patient-related risk factors and the role of physician adherence to antiemetic guidelines in reducing the residual risk of CINV.

  14. Medications for the treatment of motion sickness during evacuation, escape and rescue offshore

    A high incidence of seasickness has been recorded amongst survivors of accidents occurring offshore, whether in lifeboats or in the water. Illness is prevalent in relatively calm seas as well as conditions of severe wind and wave. When considering the occupants of totally enclosed motor propelled survival craft (TEMPSC), then the shape and design of the vessel, the lack of visual cues, the lack of forward facing seats and head restraint, the smell, and the view of others being sick are all factors which exacerbate the problem. The majority of drugs used in the treatment of nausea and vomiting are given in advance, to prevent the development of symptoms. Of the anti-emetic agents currently available, scopolamine is thought to be the most effective drug, both for the prophylaxis and treatment of seasickness. To achieve therapeutic levels quickly, and then maintain the treatment, a combination of preparations are indicated; an initial dose given by buccal tablet or injection followed by a transdermal patch to ensure long-term effectiveness.

    Cannabinoid hyperemesis syndrome is a variant of cyclical vomiting syndrome in a context of chronic cannabis usage. Our aim was to compare French cases to those identified in the international literature in order to further our knowledge of the clinical criteria, pathophysiology and treatments for cannabinoid hyperemesis syndrome. We analysed cases reported in the international literature up to 30 June 2017, obtained from the MEDLINE, PsycINFO and The Cochrane Library databases; we selected relevant articles based on title and abstract. We also analysed cases of cannabinoid hyperemesis syndrome reported to the French addictovigilance network. A systematic search through the three databases enabled us to identify 137 articles. Finally, 55 articles were selected as they involved reported cases. In total, 113 cases were reported in these 55 articles. We were thus able to analyse 29 reported French cases of cannabinoid hyperemesis syndrome. Cannabinoid hyperemesis syndrome mainly affects young male subjects who have been smoking cannabis daily for several years. Taking hot baths or showers is the most effective means of relieving the symptoms, while antiemetics and dopamine antagonists do not appear to effective for relieving nausea and vomiting. French cases display the same characteristics as the cases identified in the international literature. The pathophysiology of cannabinoid hyperemesis syndrome is unclear and several hypotheses have been put forward in the literature. We have only begun to characterise the syndrome, though there is an outbreak of cannabinoid hyperemesis syndrome in France. Copyright © 2017 Elsevier B.V. All rights reserved.

  16. Olanzapine and Betamethasone Are Effective for the Treatment of Nausea and Vomiting due to Metastatic Brain Tumors of Rectal Cancer

    Full Text Available Brain lesions originating from metastasis of colorectal cancer represent 3-5% of all brain metastases and are relatively rare. Of all distant metastases of colorectal cancer, those to the liver are detected in 22-29% of cases, while those to the lungs are detected in 8-18% of cases. In contrast, brain metastasis is quite rare, with a reported incidence ranging from 0.4 to 1.8%. Treatments for metastatic brain tumors include surgery, radiotherapy, chemotherapy and supportive care with steroids, etc. Untreated patients exhibit a median survival of only approximately 1 month. The choice of treatment for brain metastasis depends on the number of lesions, the patient's general condition, nerve findings and presence of other metastatic lesions. We herein report the case of a 78-year-old male who presented with brain metastases originating from rectal carcinoma. He suffered from nausea, vomiting, anorexia and vertigo during body movement. He received antiemetics, glycerol and whole brain radiation therapy; however, these treatments proved ineffective. Olanzapine therapy was started at a dose of 1.25 mg every night. The persistent nausea disappeared the next day, and the frequency of vomiting subsequently decreased. The patient was able to consume solid food. Olanzapine is an antipsychotic that has recently been used as palliative therapy for refractory nausea and vomiting in patients receiving chemotherapy. We consider that olanzapine was helpful as a means of supportive care for the treatment of nausea and vomiting due to brain metastasis.

    2013-01-01

    The purpose of the study was to assess insulin pump use and provide ongoing education. A quality improvement project using a pump assessment questionnaire was implemented at an endocrinology office in the southeastern United States. The questionnaire was designed to evaluate all aspects of insulin pump therapy, including pump operations, infusion set failure, management of acute complications, and usage of advanced device features. Eighty-nine patients (80% with type 1 diabetes and 20% with type 2 diabetes) completed the questionnaire at the endocrinology practice. A certified diabetes educator reviewed the questions with each patient, identifying deficiencies and training opportunities. The most common areas of deficiency identified after implementation of the assessment form included the following: expired or no basal insulin prescription in the event of pump failure or removal, no mupirocin (Bactroban®, GlaxoSmithKline, Research Triangle Park, North Carolina) prescription for suspected site infections, lack of insulin syringe if pump stopped working, failure to check urine ketones, no antiemetic prescription for sick day intervention, using manual bolus instead of bolus calculator, and lack of in-date glucagon kit. Use of a pump assessment questionnaire allows for focused discussion concerning patient behaviors related to pump operations, troubleshooting, and self-management. Incorporating use of a pump assessment questionnaire into routine practice may result in improved patient education and avoidance of adverse events specific to insulin pump therapy.

    Children with uncomplicated Plasmodium falciparum imported malaria are treated with various antimalarial regimens including mefloquine depending on national guidelines. Little is known regarding mefloquine treatment efficacy in this setting. In this prospective study, children 3 months to 16 years of age admitted in a tertiary hospital emergency ward in France with uncomplicated P. falciparum malaria were treated with oral mefloquine. Each dose was given with an antiemetic. Between 2004 and 2009, 95 children were evaluated. In all, 94% had traveled in the Indian Ocean region (Comoros and Madagascar); 79% used a malaria chemoprophylaxis, but none was fully compliant with World Health Organization recommended regimens. Main clinical features at admission were fever (91%), vomiting (44%), and headaches (44%). Hemoglobin mefloquine, and no relapse was noted within 45 days after admission. One Plasmodium vivax relapse occurred 6 months later. Vomiting within 1 hour after dosing occurred in 20% of children. Significant features associated with early vomiting by univariate analysis were a weight ≤ 15 kg, C-reactive protein ≥ 50 mg/L, and parasitemia ≥ 1%, but only low weight was significant by multivariate analysis. Mefloquine is an effective treatment for uncomplicated imported P. falciparum malaria in children returning from countries with low mefloquine resistance. Early vomiting after mefloquine dosing is frequent, especially in children < 15 kg of weight, but a second dose can be given successfully.

    2012-02-01

    INTRODUCTION: Malignant bowel obstruction (MBO) is a common complication of advanced cancer, occurring most frequently in gynaecological and colorectal cancer. Its management remains complex and variable. This is in part due to the lack of evidence-based guidelines for the clinicians involved. Although surgery should be considered the primary treatment, this may not be feasible in patients with a poor performance status or advanced disease. Advances have been made in the medical management of MBO which can lead to a considerable improvement in symptom management and overall quality of life. AREAS COVERED: This review emphasizes the importance of a prompt diagnosis of MBO with early introduction of pharmacological agents to optimize symptom control. The authors summarize the treatment options available for bowel obstruction in those patients for whom surgical intervention is not a feasible option. The authors also explore the complexities involved in the introduction of parenteral hydration and total parenteral nutrition in this group of patients. EXPERT OPINION: It is not always easy to distinguish reversible from irreversible bowel obstruction. Early and aggressive management with the introduction of pharmacological agents including corticosteroids, octreotide and anti-cholinergic agents have the potential to maintain bowel patency, and allow for more rapid recovery of bowel transit. A combination of analgesics, anti-emetics and anti-cholinergics with or without anti-secretory agents can successfully improve symptom control in patients with irreversible bowel obstruction.

    Postoperative nausea and vomiting (PONV) is one of the most common postoperative complications. Despite this, few papers have reported the incidence and independent risk factors associated with PONV in the context of oral and maxillofacial surgery (OMFS). Therefore, we sought to determine the incidence of PONV, as well as to identify risk factors for the condition in patients who had undergone OMFS under general anesthesia. A total of 372 patients' charts were reviewed, and the following potential risk factors for PONV were analyzed: age, sex, body mass index, smoking status, history of PONV and/or motion sickness, duration of anesthesia, amount of blood loss, nasogastric tube insertion and retention and postoperative opioid used. Univariate analysis was performed, and variables with a P-value less than 0.1 were entered into a multiple logistic regression analysis, wherein P-values 4 h. Furthermore, the number of risk factors was proportional to the incidence of PONV. The incidence of PONV in patients who have undergone OMFS varies from center to center depending on patient characteristics, as well as on anesthetic and surgical practice. Identifying the independent risk factors for PONV will allow physicians to optimize prophylactic, antiemetic regimens.

  3. Drug cocktail optimization in chemotherapy of cancer.

    Full Text Available BACKGROUND: In general, drug metabolism has to be considered to avoid adverse effects and ineffective therapy. In particular, chemotherapeutic drug cocktails strain drug metabolizing enzymes especially the cytochrome P450 family (CYP. Furthermore, a number of important chemotherapeutic drugs such as cyclophosphamide, ifosfamide, tamoxifen or procarbazine are administered as prodrugs and have to be activated by CYP. Therefore, the genetic variability of these enzymes should be taken into account to design appropriate therapeutic regimens to avoid inadequate drug administration, toxicity and inefficiency. OBJECTIVE: The aim of this work was to find drug interactions and to avoid side effects or ineffective therapy in chemotherapy. DATA SOURCES AND METHODS: Information on drug administration in the therapy of leukemia and their drug metabolism was collected from scientific literature and various web resources. We carried out an automated textmining approach. Abstracts of PubMed were filtered for relevant articles using specific keywords. Abstracts were automatically screened for antineoplastic drugs and their synonyms in combination with a set of human CYPs in title or abstract. RESULTS: We present a comprehensive analysis of over 100 common cancer treatment regimens regarding drug-drug interactions and present alternatives avoiding CYP overload. Typical concomitant medication, e.g. antiemetics or antibiotics is a preferred subject to improvement. A webtool, which allows drug cocktail optimization was developed and is publicly available on http://bioinformatics.charite.de/chemotherapy.

    2008-10-01

    The World Health Organization (WHO) placed migraine 19th among all causes of disability (12th in women) measured in years of healthy life lost to disability (YLD). The importance of headache disorders, particularly of the primary forms, is established by their distribution worldwide, their duration (the majority being life-long conditions) and their imposition of both disability and life-style restrictions among large numbers of people. For these reasons, headache disorders should represent a public-health priority. In the Emergency Department (ED), as elsewhere, migraine is often under-diagnosed-and under-treated when it is diagnosed. The result is likely to be failure of treatment. Particular attention to diagnosis is needed in ED patients with acute headache, since there is a higher probability of secondary headache due to underlying pathologies. According to European principles of management, acute migraine treatment generally is stepwise. Of the two main steps, the first relies on symptomatic medication, preferably NSAIDs with or without antiemetics. The second step uses specific therapies, usually triptans. Modifications to routine practice are appropriate in the ED. Parenteral administration of symptomatic therapies is a preferred first choice, whilst immediate resort to triptans may be appropriate, and achieve better outcomes, in patients with severe headache and diagnostic confirmation of migraine.

    To assess efficacy and safety of the association oxycodone/acetaminophen (oxycodone/acetaminophen) for pain treatment and disability improvement in patients with rheumatoid arthritis (RA). Patients with RA (n = 29), suffering from moderate to severe pain for more than 3 months, were included in the study, except those under RA therapy with biological drugs. The treatment started with oxycodone/acetaminophen at the dosage of 5 mg/325 mg, and then the dosage was titrated until the attainment of good pain relief. Antiemetic and laxative therapy was used for the prophylaxis of known opioid-related adverse events. Patients continued their RA therapy without changing the dosages, reported reduced pain intensity and disease activity, and improvement of disability. Forty-two percent of patients had a good clinical response to oxycodone/acetaminophen treatment, according to European League against Rheumatism (EULAR) assessment criteria, and 50 percent of patients reached the American College of Rheumatology 20 percent improvement criteria (ACR20). At the end of the study, the mean (+/- SD) daily effective oxycodone/acetaminophen dose was 13.8 (+/- 6.8) mg/720.4 (+/- 291.0) mg. No serious adverse event was observed. Nausea, vomiting, and stipsis of mild-moderate intensity were the most common adverse events. Oxycodone/acetaminophen at low dosages for the treatment of chronic pain in RA patients can be a good alternative to non-steroidal antiinflammatory drugs (NSAIDs), allowing the reduction of their consumption, while keeping RA therapy stable.

    Full Text Available Pogostemon cablin Benth. (patchouli is an important herb which possesses many therapeutic properties and is widely used in the fragrance industries. In traditional medicinal practices, it is used to treat colds, headaches, fever, nausea, vomiting, diarrhea, abdominal pain, insect and snake bites. In aromatherapy, patchouli oil is used to relieve depression, stress, calm nerves, control appetite and to improve sexual interest. Till now more than 140 compounds, including terpenoids, phytosterols, flavonoids, organic acids, lignins, alkaloids, glycosides, alcohols, aldehydes have been isolated and identified from patchouli. The main phytochemical compounds are patchouli alcohol, α-patchoulene, β-patchoulene, α-bulnesene, seychellene, norpatchoulenol, pogostone, eugenol and pogostol. Modern studies have revealed several biological activities such as antioxidant, analgesic, anti-inflammatory, antiplatelet, antithrombotic, aphrodisiac, antidepressant, antimutagenic, antiemetic, fibrinolytic and cytotoxic activities. However, some of the traditional uses need to be verified and may require standardizing and authenticating the bioactivity of purified compounds through scientific methods. The aim of the present review is to provide comprehensive knowledge on the phytochemistry and pharmacological activities of essential oil and different plant extracts of patchouli based on the available scientific literature. This information will provide a potential guide in exploring the use of main active compounds of patchouli in various medical fields.

     We report a 79-year-old patient with post-polio syndrome (PPS). In the course of this disease, recurrent upper abdominal pain and a therapy-resistant nausea developed without vomiting. In addition, the patient was limited by the combination of muscular weakness, obesity, dietary-treated diabetes and a degenerative spinal cord injury significantly in its mobility and physical capacity.  Despite extensive diagnostics, no somatic cause could be found neither for the nausea nor for the upper abdominal pain. Due to the psychological stress within the scope of the PPS, the development of a somatoform autonomic function disorder of the upper gastrointestinal tract may have occurred.  Even under combination therapy of antiemetic and pain-modulating drugs, no adequate symptom control could be achieved. In the absence of therapy alternatives and increasing psychological strain the patient was prescribed medical cannabis. Under the therapy there was a relief of the nausea symptoms and decreased pain.  Cannabis is a treatment option for treatment-resistant symptoms as part of a PPS. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Patchouli alcohol (PA, a tricyclic sesquiterpene, is one of the critical bioactive ingredients and is mainly isolated from aerial part of Pogostemon cablin (known as guanghuoxiang in China belonging to Labiatae. So far, PA has been widely applied in perfume industries. This review was written with the use of reliable information published between 1974 and 2016 from libraries and electronic researches including NCKI, PubMed, Reaxys, ACS, ScienceDirect, Springer, and Wiley-Blackwell, aiming at presenting comprehensive outline of security, pharmacokinetics, and bioactivities of PA and at further providing a potential guide in exploring the PA and its use in various medical fields. We found that PA maybe was a low toxic drug that was acquired numerously through vegetable oil isolation and chemical synthesis and its stability and low water dissolution were improved in pharmaceutics. It also possessed specific pharmacokinetic characteristics, such as two-compartment open model, first-order kinetic elimination, and certain biometabolism and biotransformation process, and was shown to have multiple biological activities, that is, immunomodulatory, anti-inflammatory, antioxidative, antitumor, antimicrobial, insecticidal, antiatherogenic, antiemetic, whitening, and sedative activity. However, the systematic evaluations of preparation, pharmaceutics, toxicology, pharmacokinetics, and bioactivities underlying molecular mechanisms of action also required further investigation prior to practices of PA in clinic.

    Full Text Available Metoclopramide is a benzamide that is a dopamine receptor, often preferred as a prokinetic agent to accelerate gastrointestinal passage in the treatment of gastroesophageal reflux disease; itis also used as an antiemetic agent in many diseases that progress with nausea-vomiting. It is effective on the digestive system both centrally and peripherally. It easily overcomes the blood-brain barrier and may create side effects pertaining to the extrapyramidal system. Acute dystonic reaction is rare among these side effects; it is, however, a condition that needs to be treated urgently. This paper presents a 5-month-old infant patient who developed acute dystonic reaction secondary to the use of Metpamid at a high dose. The diagnosis in this case was made based onpatient history. The patient%u2019s symptoms rapidly disappeared thanks to treatment with diphenhydramine. It should be remembered that metoclopramide may cause side effects in patients presenting to the emergency service with acute dystonia, soa complete history of drugs should definitely be taken for such patients.

    Cannabinoid hyperemesis syndrome (CHS) is a medical condition which was identified for the first time in 2004 and affects chronic users of cannabis. It is characterized by cyclic episodes of uncontrollable vomiting as well as compulsive bathing in hot water. The episodes have a duration of two to four days. The vomiting is recognizable by a lack of response to regular antiemetic treatment, and subsides only with cannabis abstinence, reappearing in periods of consumption of this substance. The etiology of this syndrome is unknown. Up until June 2014, 83 cases of CHS were published worldwide, four of them in Spain.The first patient of CHS at Mataró Hospital was diagnosed in 2012. Since then, five new cases have been identified. The average duration between the onset of acute CHS episodes and diagnosis is 6.1 years, similar to that observed in previously published cases, an average of 3.1 years. This "delay" of CHS diagnosis demonstrates a lack of awareness with respect to this medical condition in the healthcare profession.With the objective of providing information concerning CHS and facilitating its timely diagnosis, a series of six new cases of CHS diagnosed in Mataró Hospital is presented along with a summary of cases published between 2004 and June 2014.

    2012-04-01

    Oral chemotherapy is one of the options for the treatment of endocrine non-responsive metastatic breast cancer. A search of the online PubMed database was undertaken to identify clinical trials evaluating oral vinorelbine in metastatic breast cancer. All the clinically relevant data have been analysed in this article. A total of 31 studies including more than 1000 patients have been included into this analysis. Oral vinorelbine either as a single-agent or in combination has shown consistent efficacy results (response rates between 27% and 85% in first-line). The all-oral combination of oral vinorelbine and capecitabine has shown comparable efficacy to a taxane-based combination in a randomised phase II study. Importantly, activity has also been observed in the subset of patients previously treated with anthracyclines and taxanes. For HER2-positive patients, oral vinorelbine in combination with trastuzumab is among the most active options. Oral vinorelbine presents a manageable tolerance profile. Neutropenia is the most common adverse event and alopecia is not frequently observed. Anti-emetic prophylaxis is recommended. Taken together, these data indicate that oral vinorelbine is a highly effective and well tolerated agent which can be used in first-line and subsequent metastatic breast cancer settings. Moreover, this compound may offer the specific advantages of oral chemotherapy, as fewer and shorter hospital visits, delayed use of central venous access devices and maintained social activities.

    While chemotherapy-induced nausea and vomiting are clinically controlled in the acute (anorexia, nausea, fatigue, and other illness-type behaviors during the delayed phase (>24 h) of chemotherapy are largely uncontrolled. As the hindbrain glucagon-like peptide-1 (GLP-1) system contributes to energy balance and mediates aversive and stressful stimuli, here we examine the hypothesis that hindbrain GLP-1 signaling mediates aspects of chemotherapy-induced nausea and reductions in feeding behavior in rats. Specifically, hindbrain GLP-1 receptor (GLP-1R) blockade, via 4th intracerebroventricular (ICV) exendin-(9-39) injections, attenuates the anorexia, body weight reduction, and pica (nausea-induced ingestion of kaolin clay) elicited by cisplatin chemotherapy during the delayed phase (48 h) of chemotherapy-induced nausea. Additionally, the present data provide evidence that the central GLP-1-producing preproglucagon neurons in the nucleus tractus solitarius (NTS) of the caudal brainstem are activated by cisplatin during the delayed phase of chemotherapy-induced nausea, as cisplatin led to a significant increase in c-Fos immunoreactivity in NTS GLP-1-immunoreactive neurons. These data support a growing body of literature suggesting that the central GLP-1 system may be a potential pharmaceutical target for adjunct anti-emetics used to treat the delayed-phase of nausea and emesis, anorexia, and body weight loss that accompany chemotherapy treatments.

  13. Management of intestinal obstruction in advanced malignancy

    Directory of Open Access Journals (Sweden)

    Henry John Murray Ferguson

    2015-09-01

    Full Text Available Patients with incurable, advanced abdominal or pelvic malignancy often present to acute surgical departments with symptoms and signs of intestinal obstruction. It is rare for bowel strangulation to occur in these presentations, and spontaneous resolution often occurs, so the luxury of time should be afforded while decisions are made regarding surgery. Cross-sectional imaging is valuable in determining the underlying mechanism and pathology. The majority of these patients will not be suitable for an operation, and will be best managed in conjunction with a palliative medicine team. Surgeons require a good working knowledge of the mechanisms of action of anti-emetics, anti-secretories and analgesics to tailor early management to individual patients, while decisions regarding potential surgery are made. Deciding if and when to perform operative intervention in this group is complex, and fraught with both technical and emotional challenges. Surgery in this group is highly morbid, with no current evidence available concerning quality of life following surgery. The limited evidence concerning operative strategy suggests that resection and primary anastomosis results in improved survival, over bypass or stoma formation. Realistic prognostication and involvement of the patient, care-givers and the multidisciplinary team in treatment decisions is mandatory if optimum outcomes are to be achieved.

    The Montgomery County Coroner's Office has encountered a series of 10 infant deaths over an 8-month period in infants under 12 months old with toxicology findings that include a variety of drugs commonly found in over-the-counter (OTC) cold medications. The drugs detected were ephedrine, pseudoephedrine, dextromethorphan, diphenhydramine, chlorpheniramine, brompheniramine, ethanol, carbinoxamine, levorphanol, acetaminophen, and the anti-emetic metoclopramide. Toxicology findings were confirmed in 2 different matrices in 9 of the 10 cases and by 2 different analytical methods. The blood concentrations of the drugs and the case histories, as well as the cause of death for each infant, if available, will be given. The majority of these deaths were either toxicity from the OTC cold medications directly or as a contributory factor in the cause of death. Only two of the cases were the result of possible child abuse. Caregivers may be under the mistaken notion that OTC cold medications formulated for children are also safe for use in infants. These cases demonstrate that not only is administration of some OTC cold medications not safe, but use of OTC cold medications in infants can result in toxicity that can lead to death.

    Full Text Available Background: Nausea and vomiting is common post operative complications that often necessitate the use of antiemetic agent sand it is still a problem. This study evaluated the effect of additional fluid therapy on PONV on patients undergoing Shirodkar’s operation. Methods: In a randomized, double blind Trail, the effect of pre operative moderate fluid administration on post operative nausea and vomiting (PONV following anesthesia was studied. One hundred twenty women undergoing shirodkar surgery was randomly assigned to receive Npo fluid (control group or Npo fluid plus 10 ml.kg (moderate hydration group of ringer solution pere operation. During recovery time and in the ward nausea and vomiting were evaluated. Results: Groups were similar with respect to demographic data, surgical procedures and baseline homodynamic variables. During the recovery room and in the ward, the incidence of nausea and vomiting were significantly lower in the hydrated group as compared with control (p<0.05. Conclusion: The present study showed that moderate hydration reduces the incidence of post shirodkar surgery nausea and vomiting, and seem that IV fluid therapy is a simple, effective, safe and well-tolerated technique for prevention of postoperative nausea and vomiting

    Full Text Available Studies of active drug/excipient compatibility represent an important phase in the preformulation stage of the development of all dosage forms. The potential physical and chemical interactions between drugs and excipients can affect the chemical nature, the stability and bioavailability of drugs and, consequently, their therapeutic efficacy and safety. The present review covers the literature reports of interaction and incompatibilities of commonly used pharmaceutical excipients with different active pharmaceutical ingredients in solid dosage forms. Examples of active drug/excipient interactions, such as transacylation, the Maillard browning reaction, acid base reactions and physical changes are discussed for different active pharmaceutical ingredients belonging to different therapeutic categories viz antiviral, anti-inflammatory, antidiabetic, antihypertensive, anti-convulsant, antibiotic, bronchodialator, antimalarial, antiemetic, antiamoebic, antipsychotic, antidepressant, anticancer, anticoagulant and sedative/hypnotic drugs and vitamins. Once the solid-state reactions of a pharmaceutical system are understood, the necessary steps can be taken to avoid reactivity and improve the stability of drug substances and products.

    The aim of the study was to evaluate the role of ramosetron for the prevention of chemoradiotherapy-induced nausea and vomiting (CRINV) in patients receiving upper abdominal irradiation with concurrent 5-fluorouracil chemotherapy. Between November 2006 and April 2007, 25 patients with pancreatico-biliary cancer underwent adjuvant chemoradiotherapy. A total dose of 40 Gy was delivered using 2 Gy/fraction, 5 days a week, with 2 weeks of planned rest after 20 Gy. Concomitant 5-fluorouracil (500 mg/m 2 /day i.v. bolus) was administered for the first 3 days of each split course. During the first course of chemoradiotherapy, all patients had prophylactic metoclopramide before treatment and those refractory to metoclopramide received rescue medication with ondansetron. During the second course of chemoradiotherapy, prophylactic ramosetron was given to patients who were refractory to ondansetron. Response to antiemetics was scored in four tiers: none, no CRINV; mild, did not interfere with normal daily life; moderate, interfered with normal daily life and severe, patient bedridden because of CRINV. Fifty-six percent of the patients (14 of 25) had moderate CRINV despite metoclopramide, and received ondansetron. Ten patients who experienced moderate CRINV despite the ondansetron had prophylactic ramosetron, and 60% of the patients (6 of 10) had the symptom improved. Ramosetron proved to be an effective alternative for the control of CRINV during upper abdominal irradiation with concurrent 5-fluorouracil chemotherapy. (author)

    A previously healthy 26-yr-old male presented for an electrodiagnostic evaluation with complaints of significant right deltoid muscle atrophy and shoulder abduction weakness after receiving an intramuscular (IM) deltoid injection of an antiemetic 4 wk earlier. Electrodiagnostic evaluation confirmed an acute axillary neuropathy. We hypothesize that direct mechanical trauma to the anterior branch of the axillary nerve resulted in axillary mononeuropathy with axonal loss, although chemically induced nerve injury cannot be excluded. Injections in and about the shoulder complex are performed routinely for the purposes of vaccination, IM medication administration, deltoid trigger-point injections, and intra-articular and bursal steroid injections. Although such injections are considered routine office procedures, there is increased risk of neurovascular injury if they are performed incorrectly. The purpose of this brief report is to make practitioners aware of the potential for axillary neuropathy with such procedures, to review the salient anatomy, and to propose a potential guideline for clinical practice to minimize iatrogenic axillary neuropathy.

    Description of a comparative study in order to evaluate the sensitivity and reliability of two techniques described in literature used to detect the bronchoaspiration of enteral nutrition. Technique A consists of measuring the glucose in bronchial secretions by strips reactive to glucose-oxidase, and Technique B consists of staining the enteral diets with Methylene Blue, and then watching for the possible presence of colouring in the bronchial secretions. Our study is a contribution to the possible enhancing of the detection of bronchoaspiration, by combining both techniques. A series of 38 patients (Series A) was analyzed, who were subjected to Technique A and a further 32 patients (Series B) were subjected to both Techniques. A comparative study was made on both techniques, based on days of enteral nutrition, and it was observed that the incidence of bronchoaspiration for Series A during the first day of enteral nutrition was 25.7%, and on the following days 9.9%. In Series B, for the first day (Technique A) the percentage of 20% compared to 0% (Technique B), during the following days, 7.2% and 0.93% respectively. We related other variables, in view of their direct handling by the nursing department, such as the pressure used to inflate the pneumoplugging, amount of gastric drainage, administration of antiemetics, the correct position of the nasogastric tube and the presence of peristaltism. The statistical correlation for glucose in bronchial secretions with these variables was not significant.(ABSTRACT TRUNCATED AT 250 WORDS)

    The adverse effects of spinal anesthesia (SA) include arterial hypotension and bradycardia. The aim of this study was to compare the effects of 2 type 3 serotonin receptor antagonists in SA-induced adverse effects. Specifically, we assessed whether ramosetron was more effective than ondansetron in reducing SA-induced decreases in blood pressure (BP) and heart rate (HR). A total of 117 patients undergoing orthopedic surgery and receiving SA were intravenously administered 0.3 mg of ramosetron (n = 39, group R), 4 mg of ondansetron (n = 39, group O4), or 8 mg of ondansetron (n = 39, group O8). Systolic BP (SBP), diastolic BP (DBP), mean BP (MBP), HR, and the lowest SBP, DBP, MBP, and HR values were measured preoperatively (baseline) and intraoperatively. The incidence of postoperative nausea and vomiting, the need for rescue antiemetics, the amount of patient-controlled analgesia consumption, and pain score in the first 48 hours after surgery were determined. Baseline values did not significantly differ among the 3 groups. After SA, SBP, DBP, MBP, and HR were lower than their baseline values in all 3 groups. The differences between the baseline and the lowest values were significantly less in group R than in groups O4 and O8 with respect to SBP (P controlled analgesia consumption, or pain score. The administration of ramosetron (0.3 mg) significantly attenuated the SA-induced decrease in BP compared with 4 or 8 mg of ondansetron and HR compared with 4 mg of ondansetron.

    Full Text Available Background. Nausea and vomiting of pregnancy (NVP is the most common medical condition of pregnancy, affecting up to 85% of expecting mothers. In the USA, there is no FDA-approved medication for the treatment of NVP. Objective. To identify the primary concerns of American women leading them to contact the Motherisk NVP Helpline and to characterize the severity of their symptoms and therapy offered in order to develop improved and customized counseling for them. Methods. We reviewed the intake forms of the American women who called the NVP Helpline from 2008 to 2012. We extracted their state of residence, demographic data, severity of NVP symptoms, and other available clinical characteristics. Results. A total of 195 forms were reviewed. Of these, 86% called for information on management of NVP with/without questions about fetal drug safety, while 14% called solely about drug safety during pregnancy/breastfeeding. The majority of women were Caucasian, in their thirties, educated, employed, married and in their second pregnancy. Of them 95% were suffering from moderate-to-severe condition with 13% having hyperemesis gravidarum. Conclusion. American women need more information on the management of NVP and on a variety of its aspects in addition to the safety and effectiveness of antiemetic medications. Their leading concern was the use of doxylamine and vitamin B6 combination for NVP treatment followed by the use of ondansetron.

    The hyperemesis gravidarum is a severe illness of nauseas and vomit that is present in the first trimester of the pregnancy, it has an incidence of 0.3 to 2%, it has been associated to weight loss, electrolytic disturbances, ketonuria, dehydration and in very seldom cases spontaneous pneumomediastinum. A 21 years old female patient, primigest, in the first trimester of gestation, she started her disease with nauseas and vomiting more than 15 times during 6 hours period, odynophagia, dysphonia and pain in the cervical region, loss of 5 kilograms in the last month. The physical examination showed the patient in bad conditions, dehydration, neck with volume increased and emphysema subcutaneus, crakles until torax. Laboratory findings with hypokalemia, leukocytosis, acute kidney failure, and elevation of hepatic enzymes. The initial treatment was with intravenous fluids resuscitation, hydroelectrolytic balance restoration, antiemetic treatment and rest, it was taken TC of neck and torax, and was exclude any laryngeal and esophageal injury and perforation, but it showed air in the mediastinum. Conservative management with favorable evolution and completed resolution in 7 days. It is very important that the medical doctor must keep in mind the different diagnosis of and take an opportune decision in case of present those complications potentially fatal to the mother.

    To compare ondansetron with metoclopramide in the treatment of hyperemesis gravidarum. We enrolled 160 women with hyperemesis gravidarum in a double-blind randomized trial. Participants were randomized to intravenous 4 mg ondansetron or 10 mg metoclopramide every 8 hours for 24 hours. Participants kept an emesis diary for 24 hours; at 24 hours, they expressed their well-being using a 10-point visual numeric rating scale and answered an adverse effects questionnaire. Nausea intensity was evaluated using a 10-point visual numeric rating scale at enrollment and at 8, 16, and 24 hours. Primary analysis was on an intention-to-treat basis. Eighty women each were randomized to ondansetron or metoclopramide. Median well-being visual numeric rating scale scores were 9 (range, 5-10) compared with 9 (range, 4-10) (P=.33) and vomiting episodes in the first 24 hours were 1 (range, 0-9) compared with 2 (range, 0-23) (P=.38) for ondansetron compared with metoclopramide, respectively. Repeat-measures analysis of variance of nausea visual numeric rating scale showed no difference between study drugs (P=.22). Reported rates of drowsiness (12.5% compared with 30%; P=.01; number needed to treat to benefit, 6), xerostomia (10.0% compared with 23.8%; Phyperemesis gravidarum. However, the overall profile, particularly regarding adverse effects, was better with ondansetron. In our setting, metoclopramide was significantly less expensive than ondansetron and remained a reasonable antiemetic choice. ISRCN Register, www.isrctn.org, ISRCTN00592566. I.

    Objective To identify factors associated with prolonged Hyperemesis Gravidarum (HG). Study Design About 395 women completed a survey regarding pre-existing conditions, treatments and outcomes. Responses were compared using two-sided t-test or the F-test. Results Participants with prolongs HG are slightly younger and weight more. Pre-existing factors associated with prolonged HG include allergies and a restrictive diet. Prolonged HG is associated with hematemesis, dizziness, fainting and antiemetic treatment. Following pregnancy, those with prolonged HG reported more posttraumatic stress, motion sickness, muscle weakness and infants with irritability, severe colic and growth restriction. Conclusion Multiple pre-existing conditions and poor maternal and infant outcomes were associated with prolonged HG. The most significant condition prior to pregnancy was allergies suggesting a possible autoimmune component affecting duration of HG. In addition, the most significant lifestyle choice linked to prolonged HG was a restrictive diet. Future research is needed to determine whether a change in diet prior to pregnancy may lead to a shorter duration of HG and its associated outcomes. PMID:21916750

    Cannabinoids are effective antiemetics and the "endogenous cannabinoids" (endocannabinoids) are thought to modulate emesis in both humans and animal models. Endocannabinoids, their receptors and their metabolising enzymes are present in peripheral blood and a reduction in blood endocannabinoid concentration has been observed in individuals with excessive nausea and vomiting following parabolic flight manoeuvres. We tested the hypothesis that plasma endocannabinoid levels are similarly perturbed in women with hyperemesis gravidarum (HG), a condition where the aetiopathogenesis is still unknown, compared to normal pregnant controls. Plasma N-arachidonoylethanolamine (anandamide), N-oleoylethanolamide and N-palmitoylethanolamide were quantified in women with HG (n = 15) and matched normal pregnant controls (n = 30) using UHPLC-ESI-MS/MS utilising an isotope dilution method and selective ion monitoring. No significant differences in anandamide, oleoylethanolamide and palmitoylethanolamide levels were observed between the two groups. There were no significant correlations between these endocannabinoids and plasma haematocrit and serum urea or sodium concentrations. These results would suggest that either the circulating endocannabinoids quantified may not be key modulating factors in HG or that the expected endocannabinoid system response to the stress induced by nausea and vomiting of early pregnancy remain unchanged in women with HG.

    Advanced dementia (AD) is a terminal disease. Palliative care is increasingly becoming of critical importance for patients afflicted with AD. The primary objective of this study was to compare pharmacy cost before and after a palliative care consultation (PCC) in patients with end-stage dementia. A secondary objective was to investigate the cost of particular types of medication before and after a PCC. This was a retrospective study of 60 hospitalized patients with end-stage dementia at a large academic tertiary care hospital from January 1, 2010 to October 1, 2011, in order to investigate pharmacy costs before and after a PCC. In addition to demographics, we carried out a comparison of the average daily pharmacy cost and comparison of the proportion of subjects taking each medication type (cardiac, analgesics, antibiotics, antipsychotics and antiemetics) before and after a PCC. There was a significant decrease in overall average daily pharmacy cost from before to after a PCC ($31.16 ± 24.71 vs. $20.83 ± 19.56; p dementia patients. Our study corroborates the benefits of palliative care team intervention in managing elderly hospitalized dementia patients.

    The present guidelines are the most recent data on postoperative nausea and vomiting (PONV) and an update on the 2 previous sets of guidelines published in 2003 and 2007. These guidelines were compiled by a multidisciplinary international panel of individuals with interest and expertise in PONV under the auspices of the Society for Ambulatory Anesthesia. The panel members critically and systematically evaluated the current medical literature on PONV to provide an evidence-based reference tool for the management of adults and children who are undergoing surgery and are at increased risk for PONV. These guidelines identify patients at risk for PONV in adults and children; recommend approaches for reducing baseline risks for PONV; identify the most effective antiemetic single therapy and combination therapy regimens for PONV prophylaxis, including nonpharmacologic approaches; recommend strategies for treatment of PONV when it occurs; provide an algorithm for the management of individuals at increased risk for PONV as well as steps to ensure PONV prevention and treatment are implemented in the clinical setting.

  8. Efficacy of intravenous ondansetron to prevent vomiting episodes in acute gastroenteritis: a randomized, double blind, and controlled trial

    Full Text Available Acute gastroenteritis is one of the most common infectious diseases of childhood. Its symptoms are vomiting, diarrhea, and dehydration. In the emergency ward, intravenous rather than oral rehydration is usually preferred because of the high likelihood of emesis. Treatments to reduce emesis are of value in improving the rehydration procedure. Our study is a double-blind randomized trial and proposes the use of ondansetron as an anti-emetic drug to treat children with acute gastroenteritis. Seventy-four in-patients, aged 3 months to 15 years, were enrolled and randomly assigned to an ondansetron or placebo group. Inclusion criteria were the diagnosis of acute gastroenteritis and the absence of other diseases or allergies to drugs. A single bolus (0.15 mg/kg of ondansetron was injected intravenously; normal 0.9% saline solution was used as a placebo. This treatment induced vomiting cessation in the ondansetron group significantly in comparison to the placebo group. The length of the hospital stay and the oral rehydration fluid volume were similar in the two groups and no adverse effects were noticed. Thus, safety, low cost, and overall bene­fit of ondansetron treatment suggests that this drug can be administered successfully to children with acute gastroenteritis.

    Craniotomy patients have a high incidence of postoperative nausea and vomiting (PONV). This prospective, randomized, double-blind, multi-center study was performed to evaluate the efficacy of prophylactic ramosetron in preventing PONV compared with ondansetron after elective craniotomy in adult patients. A total of 160 American Society of Anesthesiologists physical status I-II patients aged 19-65 years who were scheduled to undergo elective craniotomy for various intracranial lesions were enrolled in this study. All patients received total intravenous anesthesia (TIVA) with propofol and remifentanil. Patients were randomly allocated into three groups to receive ondansetron (4 mg; group A, n  =  55), ondansetron (8 mg; group B, n  =  54), or ramosetron (0.3 mg; group C, n  =  51) intravenously at the time of dural closure. The incidence of PONV, the need for rescue antiemetics, pain score, patient-controlled analgesia (PCA) consumption, and adverse events were recorded 48 h postoperatively. Among the initial 160 patients, 127 completed the study and were included in the final analysis. The incidences of PONV were lower (nausea, 14% vs. 59% and 41%, respectively; P  craniotomy patients. Ramosetron at 0.3 mg was more effective than ondansetron at 4 or 8 mg for preventing PONV in adult craniotomy patients. CLINICAL RESEARCH INFORMATION SERVICE (CRIS) IDENTIFIER: KCT0000320.

    Multimodal analgesia increases the chance of successful discharge and pain control after surgery, and pregabalin is being promoted as an effective analgesic, based on placebo-controlled studies. We investigated whether adding pregabalin improved pain control and reduced opioid requests when it was added to a multimodal analgesic regimen for cosmetic surgery. One hundred and ten women who underwent same-day cosmetic surgery were randomized to receive oral pregabalin, 75 mg q12 h for five consecutive days starting the night before surgery, or identical placebos. Participants, outcomes assessors, and the statistician were blinded. The primary outcome was postoperative numerical movement-evoked pain scores at 2, 24, 48, 72, and 96 h after surgery. The secondary outcomes included pain scores at rest; incidence of moderate to severe pain; and analgesic and antiemetic requirements; as well as the incidence of nausea, vomiting, and somnolence. Based on 99 patients who completed the study, we found no difference between the groups in the primary outcome; 72 h after surgery, movement-evoked median pain scores were cosmetic surgery. Several factors could explain our findings, including the possibility of publication bias in the current literature.

    Rotavirus infections are a leading cause of severe, dehydrating gastroenteritis in children rotavirus over a decade ago, rotavirus infections still result in >200,000 deaths annually, mostly in low-income countries. Rotavirus primarily infects enterocytes and induces diarrhoea through the destruction of absorptive enterocytes (leading to malabsorption), intestinal secretion stimulated by rotavirus non-structural protein 4 and activation of the enteric nervous system. In addition, rotavirus infections can lead to antigenaemia (which is associated with more severe manifestations of acute gastroenteritis) and viraemia, and rotavirus can replicate in systemic sites, although this is limited. Reinfections with rotavirus are common throughout life, although the disease severity is reduced with repeat infections. The immune correlates of protection against rotavirus reinfection and recovery from infection are poorly understood, although rotavirus-specific immunoglobulin A has a role in both aspects. The management of rotavirus infection focuses on the prevention and treatment of dehydration, although the use of antiviral and anti-emetic drugs can be indicated in some cases. PMID:29119972

    Full Text Available Medical cannabis is the dried flowers of the female Cannabis sativa L. plant. Cannabis contains a number of active elements, including dronabinol (THC and cannabidiol (CBD. Dronabinol is usually the main ingredient. The body’s own cannabinoid system has been identified. The discovery of this system, which comprises endocannabinoids and receptors, confirmed that cannabis has a positive effect on certain illnesses and conditions. Two types of cannabinoid receptors have been identified: CB1 and CB2 receptors. The first type CB1 is mostly found in the central nervous system, modulate pain. It also has an anti-emetic effect, and has influence on the memory and the motor system. The second type of receptors CB2 is peripheral, and it is primarily found in immune system cells and it is responsible for the immunomodulatory effects of cannabinoids. Medical cannabis can help in cases of the neurodegeneration disorders, for example Parkinson’s disease, Huntington’s Disease, Amyotrophic Lateral Sclerosis. Patients generally tolerate medical cannabis well.

    The 5-hydroxytryptamine-3 receptor (5-HT 3 R) antagonist ondansetron has been clinically approved as an anti-emetic agent. Recent findings indicate that ondansetron has anti-inflammatory properties. The aim of the present study was to assess the therapeutic action of ondansetron in cerulein-induced acute pancreatitis model. Male-BALB/c mice were used in the present study. Acute pancreatitis was induced by an hourly injection of cerulein. Ondansetron was administered subcutaneously at a dose of 3 mg/kg. The messenger RNA (mRNA) expression of 5-HT 3 R in pancreatic tissue was assessed with RT-PCR. Plasma amylase, lipase, and interleukin (IL)-6 levels were evaluated. Pancreatic injury was histopathologically graded, and myeloperoxidase (MPO)-positive cells were counted. 5-HT 3 R mRNA was expressed in the pancreas. In acute pancreatitis model mice, amylase, lipase, and IL-6 levels were significantly increased in the blood. With ondansetron treatment, these levels were significantly decreased. Histopathological evaluation revealed that ondansetron attenuated the inflammatory damage in acute pancreatitis. The number of infiltrated neutrophils stained by MPO was decreased by ondansetron treatment. In summary, the 5-HT 3 R antagonist ondansetron attenuated pancreatic injury through its anti-inflammatory action. These findings suggest that ondansetron may potentially be of use for therapy of acute pancreatitis.

    Patients with advanced systemic mastocytosis (SM) (e.g. aggressive SM (ASM), SM with an associated hematologic neoplasm (SM-AHN) and mast cell leukemia (MCL)) have limited treatment options and exhibit reduced survival. Midostaurin is an oral multikinase inhibitor that inhibits D816V-mutated KIT, a primary driver of SM pathogenesis. We conducted a phase II trial of midostaurin 100 mg twice daily, administered as 28-day cycles, in 26 patients (ASM, n=3; SM-AHN, n= 17; MCL, n=6) with at least one sign of organ damage. During the first 12 cycles, the overall response rate was 69% (major/partial response: 50/19%) with clinical benefit in all advanced SM variants. With ongoing therapy, 2 patients achieved a complete remission of their SM. Midostaurin produced a ⩾50% reduction in bone marrow mast cell burden and serum tryptase level in 68% and 46% of patients, respectively. Median overall survival for the entire cohort was 40 months, and 18.5 months for MCL patients. Low-grade gastrointestinal side effects were common and manageable with antiemetics. The most frequent grade 3/4 nonhematologic and hematologic toxicities were asymptomatic hyperlipasemia (15%) and anemia (12%). With median follow-up of 10 years, no unexpected toxicities emerged. These data establish the durable activity and tolerability of midostaurin in advanced SM.

    This research aims to describe the effect of standard care (control) versus a clinical management pathway (intervention) on patient length of stay and admission rates during a public health emergency at one Australian ED. A retrospective audit of hospital records for patients who presented in May 2013 with gastroenteritis-like symptoms was undertaken following a surge in patient presentations from a Salmonella outbreak. Patients who presented with gastroenteritis-like symptoms between 15 and 19 May 2013 received care according to a clinical management pathway (intervention). The focus of the intervention was based on symptom management, including a standardised approach to analgesia, anti-emetics and rehydration. Patient characteristics, such as age and gender are described using descriptive statistics. A Mann-Whitney test was used to compare continuous data, and a Fisher's exact test was used to compare categorical data, between the two groups. Over an 8 day period, 110 patients presented with gastroenteritis-like symptoms. The median length of stay was statistically different between the two groups (P gastroenteritis-like symptoms reduced the ED length of stay. This finding is useful in future planning for similar public health emergency responses and/or for use when patients present with gastroenteritis-like symptoms on a daily basis. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    Pogostemon cablin Benth. (patchouli) is an important herb which possesses many therapeutic properties and is widely used in the fragrance industries. In traditional medicinal practices, it is used to treat colds, headaches, fever, nausea, vomiting, diarrhea, abdominal pain, insect and snake bites. In aromatherapy, patchouli oil is used to relieve depression, stress, calm nerves, control appetite and to improve sexual interest. Till now more than 140 compounds, including terpenoids, phytosterols, flavonoids, organic acids, lignins, alkaloids, glycosides, alcohols, aldehydes have been isolated and identified from patchouli. The main phytochemical compounds are patchouli alcohol, α-patchoulene, β-patchoulene, α-bulnesene, seychellene, norpatchoulenol, pogostone, eugenol and pogostol. Modern studies have revealed several biological activities such as antioxidant, analgesic, anti-inflammatory, antiplatelet, antithrombotic, aphrodisiac, antidepressant, antimutagenic, antiemetic, fibrinolytic and cytotoxic activities. However, some of the traditional uses need to be verified and may require standardizing and authenticating the bioactivity of purified compounds through scientific methods. The aim of the present review is to provide comprehensive knowledge on the phytochemistry and pharmacological activities of essential oil and different plant extracts of patchouli based on the available scientific literature. This information will provide a potential guide in exploring the use of main active compounds of patchouli in various medical fields.

    We aimed to evaluate the effect of bupivacaine and dexmedetomidine added to bupivacaine used in tranversus abdominis plane (TAP) block on postoperative pain and patient satisfaction in patients undergoing lower abdominal surgery. Patients submitted to lower abdominal surgery were enrolled in the study. After anesthesia induction, ultrasound guided TAP block was performed. TAP block was obtained with 21mL 0.9% saline in Group C (n=31), 20mL 0.5% bupivacaine+1mL saline in Group B (n=31), and 20mL 0.5% bupivacaine+1mL dexmedetomidine (100μg) in Group BD (n=31). Visual analog scale scores were lower in Group BD compared to Group C, at all time points (p0.05). The addition of dexmedetomidine to bupivacaine on TAP block decreased postoperative pain scores and morphine consumption; it also increased patient satisfaction in patients undergoing lower abdominal surgery. Dexmedetomidine did not have any effect on nausea and vomiting score and antiemetic requirement. Copyright © 2017 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda.

    Holoptelea integrifolia (Ulmaceae) is a versatile medicinal plant used in various indigenous systems of medicine for curing routine healthcare maladies. It is traditionally used in the treatment and prevention of several ailments like leprosy, inflammation, rickets, leucoderma, scabies, rheumatism, ringworm, eczema, malaria, intestinal cancer, and chronic wounds. In vitro and in vivo pharmacological investigations on crude extracts and isolated compounds showed antibacterial, antifungal, analgesic, antioxidant, anti-inflammatory, anthelmintic, antidiabetic, antidiarrhoeal, adaptogenic, anticancer, wound healing, hepatoprotective, larvicidal, antiemetic, CNS depressant, and hypolipidemic activities. Phytochemical analysis showed the presence of terpenoids, sterols, saponins, tannins, proteins, carbohydrates, alkaloids, phenols, flavonoids, glycosides, and quinines. Numerous compounds including Holoptelin-A, Holoptelin-B, friedlin, epifriedlin, β -amyrin, stigmasterol, β -sitosterol, 1, 4-napthalenedione, betulin, betulinic acid, hexacosanol, and octacosanol have been identified and isolated from the plant species. The results of several studies indicated that H. integrifolia may be used as an effective therapeutic remedy in the prevention and treatment of various ailments. However, further studies on chemical constituents and their mechanisms in exhibiting certain biological activities are needed. In addition, study on the toxicity of the crude extracts and the compounds isolated from this plant should be assessed to ensure their eligibility to be used as source of modern medicines.

    Purpose: Starting in 1992, we began using a stereotactic radiosurgical (SRS) boost for the treatment of medulloblastomas. Four patients ranging in age from 7 to 42 years old have since been treated and are the subject of this retrospective study. Methods and Materials: All patients were initially treated with a maximally debulking surgery and external beam radiotherapy, which were then followed by a stereotactic radiosurgical boost using a modified 6 MeV linear accelerator. Radiosurgical boost doses ranged from 4.50 to 10.0 Gy. Target volumes ranged from 1.1 to 8.1 cc. The procedure was well tolerated with minimal acute toxicities. Results: All four patients are alive without evidence of recurrence (at 8 to 35 months). Acute nausea and vomiting was elicited during the radiosurgical procedure in the first patient treated. We have since begun premedicating patients with antiemetics or treating under general anesthesia. Late complications consisted of panhypopituitarism in one patient, which was thought to be attributable to the previous course of whole-brain radiotherapy. We have not observed any incidence of radionecrosis in this small cohort of patients. Conclusions: Our preliminary results with the use of radiosurgery for medulloblastomas are optimistic, and we would like to suggest the inclusion of a radiosurgery boost in future clinical trials for treatment of this disease

    In this study we followed up the side effects of adjuvant radiotherapy in patients with testicular seminoma stage I over a period from 13 to 84 months (median 28 months). The most frequent side effects during radiotherapy were gastrointestinal (nausea/vomiting), psychological, cognitive, and minor sexual problems. The reported side effects were treated by antiemetics and anxiolytics. After radiotherapy, the side effects persisted in 6 % of patients, but only a few of them required additional treatment. Healthy children were born to 76 % of patients in the 18 to 39 years age group. This study shows that adjuvant radiotherapy of the para-aortic lymph nodes with the total dosage of 24 Gy in 16 daily fractions administered to testicular seminoma patients causes acceptable side effects, does not adversely affect quality of life and fertility, if the approach to treatment is individual and family consulting is provided. This makes adjuvant radiotherapy of the para-aortic lymph nodes an acceptable treatment for testicular seminoma stage I patients. (authors)

    Vertigo and dizziness are among the most common chief complaints in the emergency department. Etiologies can be categorized into three subgroups: neurootological (vestibular), medical (especially cardiovascular, metabolic), and psychiatric disorders. The diagnostic approach in the emergency department is based on a systematic analysis of case history (type, time course of symptoms, modulating factors, associated symptoms), clinical examination of the vestibular, ocular motor, and cerebellar systems (head impulse test, nystagmus, skew deviation, positioning maneuver, test of gait and stance), as well as a basal monitoring (vital signs, 12-lead ECG, blood tests). For differentiation of peripheral and central etiologies in acute vestibular syndrome, the HINTS exam (head impulse test, nystagmus, test of skew) and examination of smooth pursuit and saccades should be applied. Nonselective use of neuroimaging is not indicated due to a low diagnostic yield. Cranial imaging should be done in the following constellations: (1) detection of focal neurological or central ocular motor and vestibular signs on clinical exam, (2) acute abasia with only minor ocular motor signs, (3) presence of various cardiovascular risk factors, (4) headache of unknown quality as an accompanying symptom. Besides the symptomatic therapy of vertigo and dizziness with antiemetics or analgesics, further diagnostic differentiation is urgent to guide proper treatment. Examples are the acute therapy in cerebral ischemia, the execution of positioning maneuvers in benign paroxysmal positional vertigo, the use of corticosteroids in acute unilateral vestibulopathy, as well as the readjustment of metabolic homeostasis in medical disorders.

    Prosopis is a commercially important plant genus, which has been used since ancient times, particularly for medicinal purposes. Traditionally, Paste, gum, and smoke from leaves and pods are applied for anticancer, antidiabetic, anti-inflammatory, and antimicrobial purposes. Components of Prosopis such as flavonoids, tannins, alkaloids, quinones, or phenolic compounds demonstrate potentials in various biofunctions, such as analgesic, anthelmintic, antibiotic, antiemetic, microbial antioxidant, antimalarial, antiprotozoal, antipustule, and antiulcer activities; enhancement of H + , K + , ATPases; oral disinfection; and probiotic and nutritional effects; as well as in other biopharmaceutical applications, such as binding abilities for tablet production. The compound juliflorine provides a cure in Alzheimer disease by inhibiting acetylcholine esterase at cholinergic brain synapses. Some indirect medicinal applications of Prosopis spp. are indicated, including antimosquito larvicidal activity, chemical synthesis by associated fungal or bacterial symbionts, cyanobacterial degradation products, "mesquite" honey and pollens with high antioxidant activity, etc. This review will reveal the origins, distribution, folk uses, chemical components, biological functions, and applications of different representatives of Prosopis.

    Several in vitro studies have looked at the effect of medicinal plant extracts against Helicobacter pylori (H. pylori). Regardless of the popular use of Byrsonima crassa (B. crassa) as antiemetic, diuretic, febrifuge, to treat diarrhea, gastritis and ulcers, there is no data on its effects against H. pylori. In this study, we evaluated the anti-H. pylori of B. crassa leaves extracts and its effects on reactive oxygen/nitrogen intermediates induction by murine peritoneal macrophages. The minimal inhibitory concentration (MIC) was determined by broth microdilution method and the production of hydrogen peroxide (H2O2) and nitric oxide (NO) by the horseradish peroxidase-dependent oxidation of phenol red and Griess reaction, respectively. The methanolic (MeOH) and chloroformic (CHCl3) extracts inhibit, in vitro, the growth of H. pylori with MIC value of 1024 microg/ml. The MeOH extract induced the production H2O2 and NO, but CHCl3 extract only NO. Based in our results, B. crassa can be considered a source of compounds with anti-H. pylori activity, but its use should be done with caution in treatment of the gastritis and peptic ulcers, since the reactive oxygen/nitrogen intermediates are involved in the pathogenesis of gastric mucosal injury induced by ulcerogenic agents and H. pylori infections.

    To describe the treatment of ibuprofen intoxication with therapeutic plasma exchange in a dog (TPE). A 13-year-old male neutered mixed breed dog presented after ingesting approximately 200 mg/kg of ibuprofen. Treatment consisted of supportive medical therapy with IV fluids, gastrointestinal protectants, antiemetics and prostaglandin analogs, and TPE. A cycle of TPE was performed over 180 minutes, achieving 1.5 plasma volume exchanges. During therapy, heparinized blood and effluent samples were collected. Ibuprofen concentrations were determined in the samples by high-pressure liquid chromatography. Post TPE, the dog was continued on supportive medical therapy and was discharged 96 hours after the overdose. This report describes the use of TPE as an adjunct for ibuprofen intoxication. An 85% reduction in plasma ibuprofen concentration occurred and recovery from a potentially lethal ingestion of ibuprofen was achieved with TPE and supportive care. TPE should be considered when presented with acute ibuprofen intoxication due to the rapid and efficacious nature of therapy. © Veterinary Emergency and Critical Care Society 2017.

    low risk of bias. The large majority (80%) of the comparisons were with placebo; only 8 studies included patients with cancer receiving chemotherapy comparing cannabis with other antiemetic drugs. Concerning the efficacy of cannabis (compared with placebo) in patients with multiple sclerosis, confidence in the estimate was high in favour of cannabis for spasticity (numerical rating scale and visual analogue scale, but not the Ashworth scale) and pain. For chronic and neuropathic pain (compared with placebo), there was evidence of a small effect; however, confidence in the estimate is low and these results could not be considered conclusive. There is uncertainty whether cannabis, including extracts and tinctures, compared with placebo or other antiemetic drugs reduces nausea and vomiting in patients with cancer requiring chemotherapy, although the confidence in the estimate of the effect was low or very low. In the included studies, many adverse events were reported and none of the studies assessed the development of abuse or dependence. there is incomplete evidence of the efficacy and safety of medical use of cannabis in the clinical contexts considered in this review. Furthermore, for many of the outcomes considered, the confidence in the estimate of the effect was again low or very low. To give conclusive answers to the efficacy and safety of cannabis used for medical purposes in the clinical contexts considered, further studies are needed, with higher quality, larger sample sizes, and possibly using the same diagnostic tools for evaluating outcomes of interest.

    moderate nausea; S3 = severe nausea and/or single episode of vomiting; and S4 multiple episodes of vomiting. Results: During TBI, 18 (50%) patients were scored as complete responders (S1), 1 (3%) as a major responder (S2), 9 (25%) as minor responders (S3), and 8 (22%) as nonresponders (S4). During the following 12 h, 28 (78%) patients were free of severe nausea and vomiting (S1 or S2), whereas 8 (22%) vomited (S3 or S4). In univariate analyses, the 12-h probability of emesis was significantly higher in patients undergoing hyper diuresis (63% vs. 30%; p = 0.05), and in patients older than 45 years (65% for age >45 vs. 33% for age ≤45; p = 0.05). The probability of S3 or S4 emesis was 50% with Treatment A and 47% with Treatment B (p = 0.86). Sex, body weight, and type of conditioning chemotherapy did not influence the 12-h probability of emesis. Multivariate analysis revealed that hyper diuresis (p 0.02) and Treatment A (p = 0.04) were independently associated with radiation-induced emesis, whereas sex (p = 0.85), body weight (p = 0.13), age (p = 0.12), and type of conditioning chemotherapy (p = 0.92) were not. No early toxicity related to granisetron was observed. Conclusion: Granisetron is a well-tolerated and effective antiemetic agent that can be used as monotherapy during single-dose TBI. Good control of nausea and vomiting is obtained with this antiemetic drug, and its effect is increased when hyper diuresis is suspended during TBI

The information on the triggers and ADE were collected through a retrospective chart review of patients discharged from January to June 2008. Four hundred and ninety-seven triggers were identified in 177 charts, and each chart had 2.33 (SD = 2.7 triggers on average. The most frequent triggers were: "antiemetic" (72.1/100 charts, "abrupt cessation of medication" (70.0/100 charts and "over-sedation, drowsiness, numbness, lethargy, hypotension and fall" (34.6/100 charts. The most effective triggers for capturing ADE were "benzodiazepine antagonist", "antidiarrheal" and "rash", which, when identified in charts, were related to an event. The ADE most commonly found were related to the triggers, "abrupt cessation of medication" (8.3/100 charts, "antiemetic" (4.6/100 charts, "rash" and "anti-allergy" (2.1/100 charts. These results may help to decide which triggers are more useful in each situation.

  10. Thapsigargin-induced activation of Ca(2+)-CaMKII-ERK in brainstem contributes to substance P release and induction of emesis in the least shrew.

    2016-04-01

    Cytoplasmic calcium (Ca(2+)) mobilization has been proposed to be an important factor in the induction of emesis. The selective sarcoplasmic/endoplasmic reticulum Ca(2+)-ATPase (SERCA) inhibitor thapsigargin, is known to deplete intracellular Ca(2+) stores, which consequently evokes extracellular Ca(2+) entry through cell membrane-associated channels, accompanied by a prominent rise in cytosolic Ca(2+). A pro-drug form of thapsigargin is currently under clinical trial as a targeted cancer chemotherapeutic. We envisioned that the intracellular effects of thapsigargin could cause emesis and planned to investigate its mechanisms of emetic action. Indeed, thapsigargin did induce vomiting in the least shrew in a dose-dependent and bell-shaped manner, with maximal efficacy (100%) at 0.5 mg/kg (i.p.). Thapsigargin (0.5 mg/kg) also caused increases in c-Fos immunoreactivity in the brainstem emetic nuclei including the area postrema (AP), nucleus tractus solitarius (NTS) and dorsal motor nucleus of the vagus (DMNX), as well as enhancement of substance P (SP) immunoreactivity in DMNX. In addition, thapsigargin (0.5 mg/kg, i.p.) led to vomit-associated and time-dependent increases in phosphorylation of Ca(2+)/calmodulin kinase IIα (CaMKIIα) and extracellular signal-regulated protein kinase 1/2 (ERK1/2) in the brainstem. We then explored the suppressive potential of diverse chemicals against thapsigargin-evoked emesis including antagonists of: i) neurokinin-1 receptors (netupitant), ii) the type 3 serotonin receptors (palonosetron), iii) store-operated Ca(2+) entry (YM-58483), iv) L-type Ca(2+) channels (nifedipine), and v) SER Ca(2+)-release channels inositol trisphosphate (IP3Rs) (2-APB)-, and ryanodine (RyRs) (dantrolene)-receptors. In addition, the antiemetic potential of inhibitors of CaMKII (KN93) and ERK1/2 (PD98059) were investigated. All tested antagonists/blockers attenuated emetic parameters to varying degrees except palonosetron, however a combination of non

    Timely access to emergency contraception has the potential to reduce the number of unwanted pregnancies and subsequent abortions. A public health policy initiative in British Columbia beginning in December 2000 allowed pharmacists to provide emergency contraceptives (ECs) without a prescription. We sought to determine changes in EC use after the policy was introduced and to analyze EC use with data generated by the policy. All Ovral, Preven and Plan B EC prescriptions from Jan. 1, 1996, to Dec. 31, 2003, were identified through the BC PharmaNet and Medical Services Plan administrative databases and the data analyzed to determine changes between 1996 and 2002. Changes over time were determined in the frequency of EC provision, choice of EC agent, frequency of EC use by age group, repeat use and geographic distribution of EC prescription for the pre- and post-policy periods. Anonymized patient-specific data from treatment consent forms were used to describe the reason for EC use, interval between unprotected intercourse and EC prescription, proportion prescribed for immediate or future use, referrals for regular birth control and STD screening and concomitant antiemetic use. Consent data also provided the time in the menstrual cycle that the EC was requested. The number of EC prescriptions increased from a pre-policy mean of 8805 (99% confidence interval 7823-9787) in the years 1996 to 2000 to a post-policy total in 2002 of 17 794. Physicians prescribed the levonorgestrel regimen (Plan B) less frequently than did pharmacists. The frequency of EC use was highest among women aged 20-24 years across all study years, and all age groups demonstrated a post-policy increase in use. On average, 2.1% of the women received an EC 3 or more times a year over the period of the study. More women in urban regions received ECs than women in more rural areas of the province. Analysis of pharmacist treatment consent forms used in 2001 and 2002 showed that 56.2% of women receiving an

    Full Text Available Background: Changes in salivary flow rate were studied in head and neck (H and N cancer patients who, after receiving moderately accelerated radiotherapy (RT and concurrent chemotherapy (CT, were free of disease at 1 year. Materials and Methods: Between July 2003 and July 2005, saliva estimation was performed for 36 patients of locally advanced (AJCC stages III and IV squamous cell carcinoma of the H and N. RT, moderately accelerated (70Gy/35 fx/6 weeks along with concurrent weekly cisplatin at 35 mg/m 2 (capped at 50 mg with standard hydration and anti-emetic cover, was planned using conventional planning on telecobalt or 6 MV photons. The saliva flow rate was estimated for 5 min at rest (unstimulated and after using lemon drops (stimulated for the next 5 min at baseline (pre-treatment, 3, 6 and 12 months following treatment. Results: The median follow-up of this study was 29 months. Compared with baseline, by 3 months, a significant reduction in unstimulated (0.35 ml/min and 0.10 ml/min and stimulated (0.97 ml/min and 0.28 ml/min salivary flow rate was observed, respectively. This continued to decrease further till 6 months (0.06 ml/min and 0.17 ml/min and, by 12 months, a minimal and non-significant recovery was observed in both unstimulated (0.08 ml/min and stimulated salivary flow rates (0.22 ml/min, respectively. Conclusions: Salivary flow rates fall to a fourth of the baseline value with the above CT + RT protocol, with minimal recovery at 12 months following completion of treatment.

    To analyze the approach of emergency pediatricians to acute dehydration and their theoretical knowledge of oral rehydration, to identify the situations in which they believe oral rehydration to be indicated and its use in daily practice, as well as to determine the disadvantages of oral solutions in emergencies. We designed a survey, adapted from several similar studies, to evaluate theoretical and practical features of rehydration. The survey was applied in 23 emergency facilities in Spain. Two-hundred ninety questionnaires were included. A total of 59.3 % of the emergency pediatricians surveyed frequently used oral rehydration in acute dehydration and 10.3 % never used it. All (100 %) used it in mild dehydration (79.3 % if it was associated with vomiting), 70.3 % used it in moderate dehydration with vomiting and 22.8 % used it if it was associated with moderate diarrhea. The main disadvantages of oral rehydration were the number of visits (34.2 %), lack of space (16.6 %) and family distrust (16.2 %). Oral rehydration was used by 64.1 % of emergency pediatricians in children of all age groups and by 17.44 % only in children older than 3 months. A few (3.8 %) believed vomiting to be a contraindication; 26.9 % sometimes used an antiemetic drug and 73.8 % used a nasogastric tube to improve tolerance in the case of vomiting. Oral rehydration is widely accepted, but knowledge of its indications and techniques for application could be improved. Its main contraindications are vomiting and/or moderate dehydration; in the case of the emergency infrastructure, its main disadvantage is lack of time and workload. A nasogastric tube is a useful option to avoid an intravenous line. Guidelines for the use of oral rehydration that would reduce obstacles such as lack of time and family distrust should be developed.

    A high proportion of children with JIA will develop intolerance to MTX with anticipatory and associative gastrointestinal adverse effects. Parents and physicians frequently try to alleviate these symptoms with a variety of countermeasures. The objective of this study was to investigate the course of MTX intolerance within a 6 month period, and the effects of countermeasures on MTX intolerance severity. We performed a prospective study of 196 consecutive JIA patients treated with MTX. Intolerance was determined using the Methotrexate Intolerance Severity Score (MISS) questionnaire. MISS and countermeasures instituted by parents or physicians were determined at four time points, each 2 months apart. Countermeasures, classified into four types (antiemetic drugs, covert dosing, taste masking and complementary medicine), were analysed using non-parametric statistics and mixed linear modelling, adjusted by propensity scoring for use of countermeasures. Ninety patients (46%) showed MTX intolerance, with 58 (64%) using countermeasures at time of inclusion. Median MISS at inclusion was 11 (interquartile range = 8.0-14.25), and did not change significantly over time. No significant difference in MISS score was observed between patients receiving countermeasures and those who did not. For specific countermeasures, MISS did not change significantly after introduction. Sensitivity analysis adjusting for propensity score indicated no significant association of MISS severity on parents' decision to implement any countermeasures. MTX intolerance was present in many children with JIA and symptoms decreased little in the short term. Various modalities used as countermeasures against nausea by parents showed no discernible effect. © The Author 2017.

    Ondansetron is an antiemetic 5-HT3 receptor antagonist with proven efficacy in central balance disorder. A pilot study investigated impact on acute unilateral vestibular neuritis. A randomized clinical trial included 20 vestibular neuritis patients. Subjects received methylprednisolone-valacyclovir, associated to 5 days' metoclopramide (30 mg/d; group M, n=10) or ondansetron (8 mg/d; group O, n=10). Assessment was based on early and 1 month videonystagmography, duration of hospital stay and time to first independent walking. Blinded intention-to-treat analysis used univariate (Student test) and multivariate (linear logistic regression) analysis. Early caloric vestibular deficit was significantly lower in group O than group M (56.53% versus 84.38%; P=0.03). Vestibular preponderance did not differ between groups (8.2°/s in O versus 10.34°/s in M). At 1 month, trends were observed for vestibular deficit (43% in O versus 63.4% in M; P=0.07) and preponderance (1.67°/s in O versus 1.74°/s in M; P=0.4). Hospital stay and time to first independent walking were significantly shorter in O (2.88 versus 4.5 days (P=0.03); and 1.25 versus 2.25 days (P=0.001), respectively). Early treatment with ondansetron associated to corticosteroids and antiviral treatment reduced vestibular deficit in acute-phase vestibular neuritis as compared to reference histamine H1 receptor antagonists. The treatment did not affect central compensation. Benefit includes improved tolerance of vertigo syndrome and reduced hospital stay. These results should be confirmed on a larger series, particularly to determine the mechanism of action of 5-HT3 antagonists on vestibular function. Copyright © 2012 Elsevier Masson SAS.

    To document the incidence and timing of radiotherapy-induced nausea and vomiting (RINV) in the treatment of bone metastases among patients receiving prophylaxis with a 5-HT(3) receptor antagonist. Patients receiving single (SF) or multiple fraction (MF) palliative radiotherapy (RT) of moderate or low emetogenic risk for bone metastases were prescribed prophylactic Ondansetron. The frequency and duration of prophylaxis and the use of rescue antiemetics were left to the discretion of the treating physicians. Patients documented episodes of nausea (N) and vomiting (V) in daily diaries before and during RT, and until 10 days following RT completion. Rates of complete prophylaxis (CP) for N&V, respectively (CP = no event and no rescue medication), were calculated for the acute phase (the period from the start of RT to the first day following RT completion inclusive) and the delayed phase (the second to tenth days following RT completion inclusive). Fifty-nine patients were enrolled, and 32 were evaluable. CP rates were as follows: moderate-risk SF group (n = 16), acute phase (CP for N = 56%, CP for V = 69%) and delayed phase (CP for N = 31%, CP for V = 44%); moderate-risk MF group (n = 7), acute phase (CP for N = 71%, CP for V = 57%) and delayed phase (CP for N = 43%, CP for V = 57%); low-risk SF group (n = 8), acute phase (CP for N = 50%, CP for V = 100%) and delayed phase (CP for N = 43%, CP for V = 57%); and low-risk MF group (n = 1), acute phase (CP for N = 100%, CP for V = 100%) and delayed phase (CP for N = 100%, CP for V = 100%). Despite prophylaxis, RINV was common among patients receiving palliative radiotherapy for bone metastases, especially during the delayed phase.

    The purpose of this pilot study was to compare the response rates and daily living activities of patients with newly diagnosed gynecologic cancer treated with fosaprepitant or aprepitant in the management of chemotherapy-induced nausea and vomiting. Eligible participants were randomized to either intravenous fosaprepitant (150 mg, day 1) or oral aprepitant (125 mg on day 1 and 80 mg on days 2-3) before undergoing weekly paclitaxel (80 mg/2)(2) and monthly carboplatin (AUC 6)-based chemotherapy. In addition, standard premedications (eg, ranitidine, dexamethasone, and diphenhydramine) were administered intravenously on day 1. Response evaluation and impact on daily life were measured throughout the acute phase (0-24 hours), delayed period (days 2-4), and overall phase (0-120 hours) of the patients' initial chemotherapy cycle via the Functional Living Index-Emesis. In the current investigation, 20 gynecologic cancer subjects were treated with either fosaprepitant (n = 10) or aprepitant (n = 10) before their first chemotherapy cycle. We observed 7 overall complete responses (70%, no emetic episodes or rescue medications) in the aprepitant group and 6 (60%) in the fosaprepitant cohort (P = 0.660). In addition, both treatment groups reported similarly, favorable rates of daily living activities throughout the acute (P = 0.626) and delayed (P = 0.648) phases of cycle 1 chemotherapy. The findings from the current analysis suggest that intravenous fosaprepitant and oral aprepitant confer beneficial antiemetic prevention. Moreover, the 2 medications theoretically afford a favorable impact on daily living, thereby potentially facilitating the completion of a patient's clinically prescribed chemotherapy regimen.

    A recently developed oral serotonergic challenge test consisting of 5-Hydroxytryptophane (5-HTP, 200 mg) combined with carbidopa (CBD, 100 mg + 50 mg) exhibited dose-related neuroendocrine responsiveness and predictable pharmacokinetics. However, its applicability is limited by nausea and vomiting. A randomized, double-blind, placebo-controlled, four-way crossover trial was performed in 12 healthy male volunteers. The 5-HTP/CBD-challenge was combined with two oral anti-emetics (granisetron, 2 mg or domperidone, 10 mg) to investigate its reliability when side-effects are suppressed. The neuroendocrine response (serum cortisol and prolactin), the side-effect profile [Visual Analogue Scale Nausea (VAS)] and vomiting subjects per treatment were the main outcome measures. Compared to 5-HTP/CBD/placebo, 5-HTP/CBD/ granisetron had no impact on cortisol [% change with 95% confidence interval: -7.1% (18.9; 6.5)] or prolactin levels [-9.6% (-25.1; 9.1)]; 5-HTP/CBD/domperidone increased cortisol [+13.0% (-4.2; 33.4)], and increased prolactin extensively [+336.8% (245.7; 451.9)]. Compared to placebo, VAS Nausea increased non-significantly with granisetron [+7.6 mm (-1.3; 16.5)], as opposed to domperidone [+16.2 mm (7.2; 25.2)] and 5-HTP/CBD/placebo [+14.7 mm (5.5; 23.8)]. No subjects vomited with granisetron, compared to two subjects treated with 5-HTP/CBD/placebo and five subjects with domperidone. Compared with 5-HTP/CBD/placebo, granisetron addition decreased C(max) of 5-HTP statistically significantly different (from 1483 to 1272 ng/ml) without influencing AUC(0- infinity). Addition of granisetron to the combined 5-HTP/CBD challenge suppresses nausea and vomiting without influencing the neuroendocrine response or pharmacokinetics, enhancing its clinical applicability in future psychiatric research and drug development.

    To evaluate and describe airway complications in pediatric adenotonsillectomy. Retrospective case-control study. A chart review of patients that underwent adenotonsillectomy between 2006 and 2010 was performed. Perioperative complications, patient characteristics, and surgeon and anesthesia technique were recorded. A total of 682 charts were reviewed. Eleven cases (1.6%) of laryngospasm were identified: one was preoperative, seven occurred in the operating room postextubation, and three occurred in the recovery area. Four patients were given succinylcholine, one was reintubated, and the other cases were managed conservatively. Mean age of patients with laryngospasm was 5.87 years (standard deviation [SD], 4.01; 1.9-15.8 years). There were 12 cases (1.8%) of bronchospasm; all were treated with nebulized albuterol. Mean age of patients with bronchospasm was 5.81 years (SD, 4.17; 1.8-14.1 years). Overall, 22 patients required antiemetics (3.3%), 19 required albuterol (2.9%), and five required racemic epinephrine (0.8%). Compared to the children without airway complications, there was no difference in age, weight, American Society of Anesthesiologists status, length of surgery, need for admission, and anesthesia technique in those that had laryngospasm. Patients with bronchospasm, compared to the patients without complications, had faster surgeries (P bronchospasm (1.8%) are significantly lower than reported in the literature, reflecting refinements in modern anesthesia/surgical technique. Knowledge of at-risk patients can facilitate planning to potentially reduce the incidence of perioperative airway complications during adenotonsillectomy.

    Granisetron, a serotonin 5-HT(3) receptor antagonist, widely used as an antiemetic drug following chemotherapy, has been found to improve learning and memory. In this study, effects of granisetron on spatial recognition memory and fear memory and the involvement of nitric oxide (NO) have been determined in a Y-maze and passive avoidance test. Granisetron (3, 10mg/kg, intraperitoneally) was administered to scopolamine-induced memory-impaired mice prior to acquisition, consolidation and retrieval phases, either in the presence or in the absence of a non-specific NO synthase inhibitor, l-NAME (3, 10mg/kg, intraperitoneally); a specific inducible NO synthase (iNOS) inhibitor, aminoguanidine (100mg/kg); and a NO precursor, l-arginine (750 mg/kg). It is demonstrated that granisetron improved memory acquisition in a dose-dependent manner, but it was ineffective on consolidation and retrieval phases of memory. The beneficial effect of granisetron (10mg/kg) on memory acquisition was significantly reversed by l-NAME (10mg/kg) and aminoguanidine (100mg/kg); however, l-arginine (750 mg/kg) did not potentiate the effect of sub-effective dose of granisetron (3mg/kg) in memory acquisition phase. It is concluded that nitric oxide is probably involved in improvement of memory acquisition by granisetron in both spatial recognition memory and fear memory.

    Full Text Available Bitter taste receptors (TAS2Rs are expressed in mucous epithelial cells of the tongue but also outside the gustatory system in epithelial cells of the colon, stomach and bladder, in the upper respiratory tract, in the cornified squamous epithelium of the skin as well as in airway smooth muscle cells, in the testis and in the brain. In the present work we addressed the question if bitter taste receptors might also be expressed in other epithelial tissues as well. By staining a tissue microarray with 45 tissue spots from healthy human donors with an antibody directed against the best characterized bitter taste receptor TAS2R38, we observed an unexpected strong TAS2R38 expression in the amniotic epithelium, syncytiotrophoblast and decidua cells of the human placenta. To analyze the functionality we first determined the TAS2R38 expression in the placental cell line JEG-3. Stimulation of these cells with diphenidol, a clinically used antiemetic agent that binds TAS2Rs including TAS2R38, demonstrated the functionality of the TAS2Rs by inducing calcium influx. Restriction enzyme based detection of the TAS2R38 gene allele identified JEG-3 cells as PTC (phenylthiocarbamide-taster cell line. Calcium influx induced by PTC in JEG-3 cells could be inhibited with the recently described TAS2R38 inhibitor probenecid and proved the specificity of the TAS2R38 activation. The expression of TAS2R38 in human placental tissues points to further new functions and hitherto unknown endogenous ligands of TAS2Rs far beyond bitter tasting.

    Full Text Available Objective: Functional Living Index Emesis (FLIE is developed to evaluate the relationship between emesis and it's effects on patient's daily life and is far more relevant to detect the effectiveness of antiemetic treatment compared with self-diary reports. In this study, the efficacy of oral neurokinin-1 antagonist aprepitant on the prevention of chemotherapy-induced nausea and vomiting and quality of life is evaluated with FLIE. Study Design: Cross sectional study. Material and Methods: Sixty patients with Non-Small Cell Lung Cancer (NSCLC receiving a chemotherapy regimen consisting of Cisplatin and Docetaxel were evaluated. The patients were prospectively randomized to two groups before the first cycle of chemotherapy. Patients in Group A (31 patients received 3 daily doses of aprepitant along with oral ondansetron and dexamethasone. The patients in group B (29 patients received only ondansetron and dexamathasone. The efficacy of both regimens was evaluated by a modified Turkish version of FLIE scale consisting of 18 questions. Results: The number of patients with complete response was 31 in the whole group. Of these 18 patients (58% were in Group A (Aprepitant and 13 patients in group B (42%. Median FLIE score in group A was 24.97 (±12.45 while it was 38.1 (±26.987 in group B and the difference was statistically significant (p=0.022. Total score >20 was seen in only 5 of 31 patients in aprepitant group (16% showing the significant efficiency of aprepitant on quality of life, while in group B, 13 of 29 patients (44% had total scores >20 (p=0.02. Conclusion: Regarding these findings, it is certain to state that aprepitant in combination with other drugs optimizes protection against both nausea and vomiting compared to the prior standard of care, and must be recommended as first-line therapy for patients who are treated with moderately or highly emetogenic chemotherapy.

    Full Text Available CONTEXT AND OBJECTIVE: Chemotherapy-induced emesis is a limiting factor in treating children with malignancies. Intensive chemotherapy regimens along with emetogenic drug administration have increased the frequency and severity of emesis and nausea. Our study was designed to consider the importance of this problem and the need for improvement in emesis treatment for patients receiving chemotherapy. Our objective was to compare the efficacy and safety of the antiemetic drug granisetron and a regimen of metoclopramide plus dimenhydrinate. DESIGN AND SETTING: Open, prospective and randomized study at Instituto de Oncologia Pediátrica, Department of Pediatrics, Universidade Federal de São Paulo. METHODS: From February to August 1994, 26 patients (mean age: 14 years with osteosarcoma received 80 chemotherapy cycles of iphosphamide (2,500 mg/m² plus epirubicin (75 mg/m² or carboplatin (600 mg/m², or epirubicin (75 mg/m² plus carboplatin (600 mg/m². Eighty chemotherapy treatments were analyzed regarding nausea and vomiting control. Patients were randomized to receive either a single dose of granisetron (50 µg/kg or metoclopramide (2 mg/kg plus dimenhydrinate (5 mg/kg infused over eight hours. Emesis and nausea were monitored for 24 hours by means of the modified Morrow Assessment of Nausea and Emesis. Statistical analysis utilized the chi-squared, Student t and Mann-Whitney tests, plus data exploration techniques. RESULTS: 62.5% of the patients undergoing chemotherapy responded completely to granisetron, whereas 10% responded to metoclopramide plus dimenhydrinate (p < 0.0001. No severe adverse reactions were found in either of the treatments given. CONCLUSION: In children and adolescents with osteosarcoma, granisetron was safe and more efficient than metoclopramide plus dimenhydrinate for controlling chemotherapy-induced emesis and nausea.

    Despite advances with new therapies, a significant proportion of patients (>30%) suffer delayed-onset chemotherapy-induced nausea and vomiting (CINV) despite use of antiemetics. APF530 is a sustained-release subcutaneous (SC) formulation of granisetron for preventing CINV. APF530 pharmacokinetics, safety, and efficacy were studied in two open-label, single-dose Phase II trials (C2005-01 and C2007-01, respectively) in patients receiving moderately emetogenic chemotherapy or highly emetogenic chemotherapy. In C2005-01, 45 patients received APF530 250, 500, or 750 mg SC (granisetron 5, 10, or 15 mg, respectively). In C2007-01, 35 patients were randomized to APF530 250 or 500 mg SC. Injections were given 30 to 60 minutes before single-day moderately emetogenic chemotherapy or highly emetogenic chemotherapy. Plasma granisetron was measured from predose to 168 hours after study drug administration. Safety and efficacy were also evaluated. APF530 pharmacokinetics were dose proportional, with slow absorption and elimination of granisetron after a single SC dose. Median time to maximum plasma concentration and half-life were similar for APF530 250 and 500 mg in both trials, with no differences between the groups receiving moderately and highly emetogenic chemotherapy. Exposure to granisetron was maintained at a therapeutic level over the delayed-onset phase, at least 168 hours. Adverse events in both trials were as expected for granisetron; injection site reactions (eg, erythema and induration) were predominantly mild and seen in ≤20% of patients. Complete responses (no emesis, with no rescue medication) were obtained in the acute, delayed, and overall phases in ≥80% and ≥75% of patients in both trials with the 250 and 500 mg doses, respectively. After a single injection of APF530, there were dose-proportional pharmacokinetics and sustained concentrations of granisetron over 168 hours. The 250 and 500 mg doses were well tolerated and maintained therapeutic granisetron

This analysis determined the emetogenicity of multiagent, multiday chemotherapy and the Granisetron Transdermal System (GTDS; Sancuso®.Methods: This was a retrospective analysis of a multicenter, randomized, double-blind, phase III noninferiority trial of GTDS versus oral granisetron in patients receiving 3 days of multiagent moderately or highly emetogenic chemotherapy, regardless of granisetron formulation. Emesis was defined as vomiting/retching or the use of rescue medication. Logistic regression and classification trees were used to determine the optimal combination of Hesketh scores over the multiagent, multiday regimens for the prediction of emesis.Results: Of 393 patients, 272 (69.2% were chemotherapy naïve. The most common types of cancer were lung (30.5% and gynecologic (21.9%. The most common chemotherapeutic regimen (in 14.2% of patients was cisplatin plus etoposide on days 1–3. The best binary emesis predictor was day 1 Hesketh score. Patients with a day 1 Hesketh score of 5 had the highest rate of emesis (62.5% versus patients with a score < 5 (31.7%. For patients with day 1 Hesketh score < 5, only 14.3% of those receiving only one drug on day 1 experienced emesis.Conclusion: Hesketh emetogenicity scores of individual agents are applicable to multiday, multiagent chemotherapeutic regimens in patients receiving antiemetics.Keywords: chemotherapy-induced nausea and vomiting, emetogenicity, granisetron, clinical trial, retrospective analysis

    In recent studies, patients have reported an increased use of complementary and alternative medicine (CAM). Acupuncture is a popular complementary therapy for patients with cancer. This article will provide current cancer treatment providers with information on acupuncture as well as the research conducted on cancer symptoms and side effects of cancer treatments. Antiemetic studies are the most prevalent and contain the most promising results. Several studies have found that acupuncture significantly reduces the number of emesis (vomiting) episodes for patients receiving chemotherapy. While studies on pain control vary due to the heterogeneity of pain, there are few studies investigating pain caused from cancer and the removal of cancerous tumors. These studies, while promising, provide basic results that need further investigation for more definitive results. Although relatively few studies have been done on anxiety and depression, several researchers have found acupuncture to be just as effective as or more effective than antidepressants for patients without cancer. Studies on breathlessness, while small, have shown acupuncture to have a significant positive effect on chronic obstructive pulmonary disease, breathlessness associated with end-stage cancer, and asthma. Researchers studying xerostomic individuals who have received salivary gland irradiation found significant positive results in salivary flow rates compared to baseline. Patients with hot flashes due to hormonal imbalance may benefit from the use of acupuncture. A recent pilot study showed improvement of chronic postchemotherapy fatigue following acupuncture treatments. Many individuals with cancer have turned to acupuncture because their symptoms persisted with conventional treatments or as an alternative or complement to their ongoing treatments. Despite the immense popularity in the community, few large randomized trials have been conducted to determine the effects acupuncture has on cancer symptoms

  7. Pharmacokinetics of Cannabinoids

    Full Text Available Delta-9-tetrahydrocannabinol (Δ-9-THC is the main psychoactive ingredient of cannabis (marijuana. The present review focuses on the pharmacokinetics of THC, but also includes known information for cannabinol and cannabidiol, as well as the synthetic marketed cannabinoids, dronabinol (synthetic THC and nabilone. The variability of THC in plant material (0.3% to 30% leads to variability in tissue THC levels from smoking, which is, in itself, a highly individual process. THC bioavailability averages 30%. With a 3.55% THC cigarette, a peak plasma level of 152±86.3 ng/mL occured approximately 10 min after inhalation. Oral THC, on the other hand, is only 4% to 12% bioavailable and absorption is highly variable. THC is eliminated from plasma in a multiphasic manner, with low amounts detectable for over one week after dosing. A major active 11-hydroxy metabolite is formed after both inhalation and oral dosing (20% and 100% of parent, respectively. THC is widely distributed, particularly to fatty tissues, but less than 1% of an administered dose reaches the brain, while the spleen and body fat are long-term storage sites. The elimination of THC and its many metabolites (from all routes occurs via the feces and urine. Metabolites persist in the urine and feces for severalweeks. Nabilone is well absorbed and the pharmacokinetics, although variable, appear to be linear from oral doses of 1 mg to 4 mg (these doses show a plasma elimination half-life of approximately 2 h. As with THC, there is a high first-pass effect, and the feces to urine ratio of excretion is similar to other cannabinoids. Pharmacokineticpharmacodynamic modelling with plasma THC versus cardiac and psychotropic effects show that after equilibrium is reached, the intensity of effect is proportional to the plasma THC profile. Clinical trials have found that nabilone produces less tachycardia and less euphoria than THC for a similar antiemetic response.

    To study the prevalence of self-medication among pharmacy customers in rural areas of Portugal, to assess possible predictors of self-medication and to find out whether there was a seasonal dependence in the purchase of drugs for self-medication. A cross-sectional study during four different periods of a year was conducted. Community pharmacies of rural areas of Portugal were invited to participate and pharmacists were asked to recruit one person every hour during the opening hours and administer a questionnaire. Drugs dispensed were classified according to the Anatomical Therapeutic Chemical Classification system up to the second level. Prevalence of self-medication is defined as the percentage of patients acquiring a medicine that was not prescribed (written) or recommended (orally) by a physician. The prevalence of self-medication was 21.5%. Main therapeutic groups acquired for self-medication were "other alimentary tract and metabolism products" (A16; proportion acquired for self-medication= 75.0%), "throat preparations" (R02; 74.7%), "antiemetics and antinauseants" (A04; 70.0%), "cough and cold preparations" (R05; 56.5%), and "nasal preparations" (R01; 50.0%). Variables found to be predictors of self-medication were age, type of health professional or person consulted when a mild health problem occurred, time elapsed since last visit to the physician and time waited between setting an appointment and the actual visit. Seasonality seemed to occur for only "cough and cold preparations", for "dermatologicals" and for "anti-inflammatory and anti-rheumatic products". In rural Portugal about one fifth of the pharmacy customers engaged in self-medication. However, further research should be made to address appropriateness of self-medication.

    Expeditions provide an opportunity for travelers to undertake specialized travel to more extreme destinations in the security of an expeditionary group with medical coverage. Little is known about the illnesses and injuries occurring to expeditioners in Mongolia or access to dental care in the local population. This study was designed to investigate the prevalence of health problems suffered by travelers and managed among the local population on a research expedition to Mongolia. In June 2005, the expedition physician (MTMS) and dentist (DD) prospectively diagnosed and recorded all illnesses and injuries among 16 travelers (eight males and eight females) as well as any indigenous people on a 22-day paleontological expedition to the Mongolian Gobi Desert. There were 53 health presentations and 14 dental problems among the indigenous population and the Mongolian escort. Males and females presented in equal proportions with the average age of 49 years (SD = 16). Presentations involved locomotor/accident (32%), dermatological (23%), gastrointestinal (19%), neurological (17%), psychological (6%), and with other systems (11%). Most accidents were due to lacerations (85%). Presentations were highest on days 4 and 5 (10% or 18%). Females were significantly more likely to present later in the expedition (p= 0.013). One quarter (25%) were handled conservatively with 28% requiring topical treatments with others requiring antiemetics (9%) and anti-inflammatory drugs (4%). There were no dental concerns reported among the expeditioners, although there were 14 cases among the indigenous population. While there were no deaths on the expedition, there were two major incidents, one of which required emergency evacuation. The health problems encountered were largely similar to those reported for other expeditions. The most common problems included trauma as well as dermatological, dental, gastrointestinal, and neurological conditions. It is important that expedition teams are

    Agarwood is a traditional Chinese medicine used as a clinical sedative, carminative, and antiemetic drug. Agarwood is formed in Aquilaria sinensis when A. sinensis trees are threatened by external physical, chemical injury or endophytic fungal irritation. However, the mechanism of agarwood formation via chemical induction remains unclear. In this study, we characterized the transcriptome of different parts of a chemically induced A. sinensis trunk sample with agarwood. The Illumina sequencing platform was used to identify the genes involved in agarwood formation. A five-year-old Aquilaria sinensis treated by formic acid was selected. The white wood part (B1 sample), the transition part between agarwood and white wood (W2 sample), the agarwood part (J3 sample), and the rotten wood part (F5 sample) were collected for transcriptome sequencing. Accordingly, 54,685,634 clean reads, which were assembled into 83,467 unigenes, were obtained with a Q20 value of 97.5%. A total of 50,565 unigenes were annotated using the Nr, Nt, SWISS-PROT, KEGG, COG, and GO databases. In particular, 171,331,352 unigenes were annotated by various pathways, including the sesquiterpenoid (ko00909) and plant-pathogen interaction (ko03040) pathways. These pathways were related to sesquiterpenoid biosynthesis and defensive responses to chemical stimulation. The transcriptome data of the different parts of the chemically induced A. sinensis trunk provide a rich source of materials for discovering and identifying the genes involved in sesquiterpenoid production and in defensive responses to chemical stimulation. This study is the first to use de novo sequencing and transcriptome assembly for different parts of chemically induced A. sinensis. Results demonstrate that the sesquiterpenoid biosynthesis pathway and WRKY transcription factor play important roles in agarwood formation via chemical induction. The comparative analysis of the transcriptome data of agarwood and A. sinensis lays the foundation

    A cross-sectional survey was conducted to investigate the associations among smoking, drinking, betel quid chewing and pregnancy-related nausea and vomiting (N/V) in Taiwanese aboriginal women. A total of 901 aboriginal women from 11 hospitals were recruited into this study. A structured questionnaire on demographic and obstetric information, smoking history, alcohol consumption, betel quid chewing habits, and N/V by checklist was used to collect data. The findings of this study indicated that the prevalence of N/V, maternal smoking, drinking, and betel quid chewing were 75.6% (n = 682), 22.8% (n = 201), 31.9% (n = 287), and 34.7% (n = 313) respectively. Multiple logistic regression with adjustment for age, body mass index and antiemetics use revealed significant relationships between smoking habits and N/V before confirmation of pregnancy and during pregnancy. In comparison with those who did not smoke, women smoking in excess of 10 cigarettes a day before pregnancy were 1.65 times more likely to develop N/V; and women smoking in excess of 10 cigarettes a day during pregnancy were 2.79 times more likely to develop N/V. Based on the findings of this study, smoking was associated, with a dose-response effect, with pregnancy-related N/V. Reducing the intake of cigarettes could decrease the risk of pregnancy-related N/V. Health care providers should help these women decrease their uncomfortable symptoms and improve their experiences of pregnancy and birth outcome during critical times.

    Caffeine has both excitatory and vasoconstrictive effects on central nervous system. Caffeine use might be associated with development and chronification of migraine. We aimed to evaluate the effect of caffeine cessation on the acute treatment of migraine. We prospectively recruited migraine patients who consumed caffeine drinks daily and instructed them to discontinue their caffeine intake. Triptans were prescribed for acute treatment. Patients were followed up after at least two weeks after screening and evaluated the efficacy of acute treatment with the migraine assessment of current therapy (Migraine-ACT) questionnaire. Excellent efficacy was defined as Migraine-ACT score of 4. Chronic migraine, body mass index, allodynia, depression, anxiety, antiemetic use, and use of prophylactic medication were included in the multivariate analysis if the univariate p caffeine intake (abstinence group). The efficacy of acute treatment was assessed at median 34.5 days (interquartile range, 28-89) after the screening. Twenty-six patients (72.2 %) in the abstinence group and 29 (40.3 %) in the non-abstinence group reported an excellent efficacy (p = 0.002). The abstinence group also showed a trend toward greater reduction of headache impact test-6 (HIT-6) scores (p = 0.085). Caffeine abstinence was independently associated with an excellent efficacy of acute treatment (multivariate odds ratio, 3.2; 95 % confidence interval, 1.2-8.4; p = 0.018) after controlling for covariates. Caffeine abstinence is associated with better efficacy of acute migraine treatment. Our uncontrolled study results encourage a further confirmatory study on this issue.

    Rolapitant is a selective and long-acting neurokinin-1 receptor antagonist approved in an oral formulation in combination with other antiemetic agents for the prevention of delayed chemotherapy-induced nausea and vomiting in adults. This was a phase 1 open-label, parallel-group pharmacokinetic and safety study of a single oral dose of 180 mg of rolapitant and its major active metabolite, M19, in subjects with mild and moderate hepatic impairment compared with healthy matched controls. Pharmacokinetics were assessed by a mixed-model analysis of variance of log-transformed values for maximum observed plasma concentration (C max ), observed time at C max (t max ), area under the plasma concentration-time curve (AUC) from time 0 to the time of the last quantifiable concentration (AUC 0-t ), and AUC from time 0 to 120 hours (AUC 0-120 ), with hepatic group as a fixed effect. Mean rolapitant C max , AUC 0-t , and AUC 0-120 were similar in the mild hepatic impairment and healthy control groups. In subjects with moderate hepatic impairment, AUC 0-t was similar and C max was 25% lower than in healthy controls. Mean M19 C max and AUC 0-t were similar in the mild hepatic impairment group and healthy controls, but impairment versus healthy controls. Fraction of unbound rolapitant was comparable in all groups for rolapitant and M19. Rolapitant was well tolerated in all groups, without serious adverse events. Pharmacokinetic differences between healthy subjects and those with mild or moderate hepatic impairment are unlikely to pose a safety risk and do not warrant predefined dosage adjustment in the presence of hepatic impairment. © 2018, The American College of Clinical Pharmacology.

    There are currently different groups of drugs for the pharmacotherapy of vertigo, nystagmus and cerebellar disorders: antiemetics; anti-inflammatories, antimenieres, and antimigraineous medications and antidepressants, anticonvulsants, aminopyridines as well as acetyl-DL-leucine. In acute unilateral vestibulopathy, corticosteroids improve the recovery of peripheral vestibular function, but currently there is not sufficient evidence for a general recommendation. There is insufficient evidence to support the view that 16 mg t. i. d. or 48 mg t. i. d. betahistine has an effect in Menière's disease. Therefore, higher dosages are recommended. In animal studies, it was shown that betahistine increases cochlear blood flow. In vestibular paroxysmia, oxcarbazepine was effective (one randomized controlled trial (RCT)). Aminopyridines are recommended for the treatment of downbeat nystagmus (two RCTs) and episodic ataxia type 2 (EA2, one RCT). There has been no RCT on the efficacy of beta-blockers or topiramate but one RCT on flunarizine in vestibular migraine. Based on clinical experience, a treatment analogous to that for migraine without aura can be recommended. Acetyl-DL-leucine improved cerebellar ataxia (two observational studies); it also accelerated central compensation in an animal model of acute unilateral lesion, but RCTs were negative. There are ongoing RCTs on treatment of vestibular paroxysmia with carbamazepine (VESPA), acute unilateral vestibulopathy with betahistine (BETAVEST), vestibular migraine with metoprolol (PROVEMIG), benign paroxysmal positional vertigo with vitamin D (VitD@BPPV), EA2 with 4-aminopyridine versus acetazolamide (EAT-2-TREAT), and cerebellar ataxias with acetyl-DL-leucine (ALCAT).

    Full Text Available Cancer patient receive various cytotoxic drugs in association with antiemetic drugs such as 5HT3 receptor antagonists as their chemotherapy regimen. 5HT3 receptor antagonists have been reported to produce changes in ECG parameter. There are only a few studies about cardiovascular events of these drugs in patient receiving potentially cardiotoxic chemotherapies. The subject of this study is to evaluate ECG changes after administration of chemotherapeutic agents and granisetron (the most commonly used 5HT3 antagonist in Iran in adults with cancer. For this clinical trial study, all cancer patients referred to department of radiation oncology of Imam Hossein Hospital since August 2005 to March 2006 were evaluated if they had inclusion criteria. Granisetron (3 mg was infused intravenously over 30 seconds just a few minutes before chemotherapeutic agent administration. The 12-lead ECG recording was obtained before and 90 minutes after infusion of granisetron. One cardiologist determined PR, QRS, QTc intervals and heart rate of all ECGs. During the study period 54 patients fulfilled our criteria. With paired t-test, the PR and QTc intervals, but not QRS interval showed statistically significant prolongation after drug infusion (P < 0.0001, and heart rate showed statistically significant decrease (P < 0.0001. The ECG findings of chemotherapeutic agents and granisetron administration were prolongation of PR and QTc intervals and decrease of heart rate (P < 0.0001. Although these changes did not cause clinical signs, with keeping in mind that there may be possible drug-drug interactions and preexisting cardiac comorbidities in cancer patient, it seems reasonable and necessary to consider physical condition specifically cardiac condition and drug usage of each patient, while designing chemotherapy regimen and supportive drugs.

    A randomized controlled trial was performed to assess the outcome of early oral postoperative feeding (EOF) compared with traditional oral feeding (TOF) in gynecologic oncology patients undergoing a complex laparotomy, including upper abdominal surgery. Patients aged 18-75 years, undergoing an elective laparotomy and with a preoperative suspicion of gynecologic malignancy, were eligible. Exclusion criteria included infectious conditions, intestinal obstruction, severe malnutrition, American Society of Anesthesiologists score C4, intestinal resection, and postoperative stay in the intensive care unit lasting 24 h. Patients allocated to EOF received liquid diet in the first postoperative day and then regular diet. Patients received traditional feeding scheme until resolution of postoperative ileus to start liquid diet. The primary end-point of the trial was length of hospital stay. Between January 1, 2007, and November 17, 2007, a total of 143 patients were randomized to receive either EOF or TOF. Hospital stay for patients who received EOF (n=71) was 4.7 vs. 5.8 days for the TOF group (n=72) (P=0.006). The mean level of postoperative satisfaction was significantly higher in the EOF group (82.8 vs. 71.7 mm, P B 0.001). Patients who received the TOF scheme had significantly higher overall postoperative complications (39 vs. 17% in EOF group, P=0.003) and infective complications (14% in TOF group vs. 3% in EOF group, P=0.017). Variables such as nausea and vomiting, analgesic and antiemetic requirement as well as level of pain and quality of life were not different between groups. On the basis of these findings, the policy of EOF should be used after a complex gynecologic oncologic laparotomy.

    This review summarizes the recommendations for the prophylaxis of nausea and vomiting in adults receiving highly emetogenic chemotherapy (HEC) which includes cisplatin, mechlorethamine, streptozocin, cyclophosphamide >1500 mg/m 2 , carmustine, dacarbazine, and the combination of an anthracycline and cyclophosphamide (AC) administered to women with breast cancer, as agreed at the MASCC/ESMO Antiemetic Guidelines Update meeting in Copenhagen in June 2015. A systematic review of the literature using PubMed and the Cochrane Database from 2009 to June 2015 was performed. The NK 1 -receptor antagonists netupitant (300 mg given in combination with palonosetron 0.5 mg as NEPA) and rolapitant have both completed phase II and III programs and were approved by FDA (both) and EMA (NEPA) in 2014-2015. Addition of one of these agents (or of (fos)aprepitant) to a combination of a serotonin (5-HT) 3 -receptor antagonist and dexamethasone improved the number of patients with a complete response (no emesis and no rescue medication) days 1-5 after AC HEC with 8-9 % and after non-AC HEC by 8-20 %. Olanzapine has improved control of delayed nausea as compared to aprepitant in a randomized open designed study. In the prophylaxis of delayed nausea and vomiting, metoclopramide is an option instead of aprepitant in patients receiving cisplatin-based chemotherapy and dexamethasone is an option instead of aprepitant in patients receiving AC chemotherapy. Two new NK 1 -receptor antagonists (netupitant and rolapitant) have been included in the updated recommendations as additional options to aprepitant or fosaprepitant. Addition of one of these NK 1 -receptor antagonists to a combination of a 5-HT 3 -receptor antagonist and dexamethasone is recommended in both non-AC HEC and AC HEC. Olanzapine is included as an option in HEC in particular if nausea is the main symptom.

    Neurokinin-1 receptor antagonists (NK1 RAs) are commonly coadministered with a 5-HT3 RA such as palonosetron to prevent nausea and vomiting induced by chemotherapy. Netupitant, a new highly selective NK1 RA, is both a substrate for and a moderate inhibitor of CYP3A4. Three studies were designed to evaluate the potential drug-drug interaction of netupitant with palonosetron and of the fixed dose combination of netupitant and palonosetron, NEPA, with an inhibitor (ketoconazole), an inducer (rifampicin) and a substrate (oral contraceptives) of CYP3A4. Study 1 was a three-way crossover in 18 healthy subjects receiving netupitant alone, palonosetron alone, and the combination of both antiemetics. Studies 2 and 3 were two-way crossover trials where healthy subjects received NEPA (the fixed dose combination of netupitant and palonosetron). In study 2, 36 subjects received NEPA alone (day 1) and in combination with ketoconazole or rifampicin. In study 3, 24 healthy women received ethinylestradiol/levonorgestrel alone or in combination with NEPA (day 1). There were no significant pharmacokinetic interactions between netupitant and palonosetron. Ketoconazole increased netupitant area under curve (AUC) by 140 % and C max by 25 %. Rifampicin decreased netupitant AUC by 83 % and C max by 62 %. NEPA did not significantly affect exposure to ethinylestradiol, while systemic exposure to levonorgestrel increased by 40 %, but this was not considered clinically relevant. There were no clinically relevant interactions between netupitant and palonosetron, or between NEPA and oral contraceptives. The coadministration of NEPA with inhibitors or inducers of CYP3A4 may require dose adjustments. Treatments were well tolerated.

    An expanding array of options for prevention and treatment of chemotherapy-induced nausea and vomiting (CINV), including regimens containing olanzapine or recently approved neurokinin 1 (NK 1 ) receptor antagonists, are reviewed. Up to 80% of patients receiving chemotherapy have CINV. Current practice guidelines recommend that patients treated with highly emetogenic chemotherapy also receive a 3-drug antiemetic regimen initiated on the day of and continued for 3 days after chemotherapy administration, with the most commonly used 3-drug regimen consisting of an NK 1 receptor antagonist, a 5-hydroxytryptamine type 3 (5-HT 3 ) receptor antagonist, and dexamethasone. Developments in the area of CINV management in recent years include the use of olanzapine in combination with a 5-HT 3 antagonist and dexamethasone; Food and Drug Administration (FDA) approval of the NK 1 receptor antagonist rolapitant, which provides a longer duration of effect than aprepitant; FDA approval of a combination product containing palonosetron and the NK 1 receptor antagonist netupitant; and revisions of U.S. practice guidelines ending palonosetron's status as the preferred 5-HT 3 antagonist for prevention of CINV associated with moderately or highly emetogenic chemotherapy. Newer therapeutic options for the management of CINV are equivalent to standard-of-care regimens in terms of efficacy and toxicity. While the NK 1 receptor antagonist rolapitant and a product combining palonosetron and netupitant have potential advantages over standard therapy in terms of convenience or pharmacologic properties, their relatively high costs must be considered.

    Purpose: to evaluate the feasibility, safety and efficacy of daily temozolomide concurrent with postoperative radiotherapy in malignant glioma. Patients and methods: from 11/1999 to 03/2003, n = 81 patients aged 15-72 years (median 52 years, karnofsky score 80-100% in 83%) suffering from primary glioblastoma (n = 47), anaplastic astrocytoma (n = 6), anaplastic oligodendroglioma (n = 16), and recurrent glioma (n = 12) were treated. Patients with primary gliomas received a combination of postoperative radiotherapy (60 Gy/1.8- to 2.0-Gy fractions) and daily oral temozolomide (75 mg/m{sup 2}) at all irradiation days (30-33 doses), while recurrent tumors were treated with 45-60 Gy and temozolomide. Initially, 6/81 patients had daily temozolomide doses of 50 mg/m{sup 2}. Results: in total, 70/81 patients (86%) completed both radio- and chemotherapy. Grade 1 nausea/vomiting was seen in 28%, grade 2 in 11%, grade 3 in 1%. Antiemetics were applied in 41%. Hematologic toxicities were observed as follows: leukopenia grade 3/4 1%, lymphopenia grade 3/4 46%, thrombopenia grade 3/4 1%. Two patients under dexamethasone suffered herpes encephalitis after one and 16 doses of temozolomide (75 mg/m{sup 2}). Median survival was 15 months for glioblastoma. In oligodendroglioma patients, a 4-year survival rate of 78% was observed. Conclusion: postoperative radiochemotherapy with 30-33 daily doses of temozolomide (75 mg/m{sup 2}) is safe in patients with malignant glioma. The combined schedule is effective in oligodendroglioma patients and may prolong survival in glioblastoma. Effort should be taken to minimize corticosteroid doses, since both steroids and temozolomide lead to immunosuppression. (orig.)

    Cannabidiol (CBD) is a phytocannabinoid with therapeutic properties for numerous disorders exerted through molecular mechanisms that are yet to be completely identified. CBD acts in some experimental models as an anti-inflammatory, anticonvulsant, anti-oxidant, anti-emetic, anxiolytic and antipsychotic agent, and is therefore a potential medicine for the treatment of neuroinflammation, epilepsy, oxidative injury, vomiting and nausea, anxiety and schizophrenia, respectively. The neuroprotective potential of CBD, based on the combination of its anti-inflammatory and anti-oxidant properties, is of particular interest and is presently under intense preclinical research in numerous neurodegenerative disorders. In fact, CBD combined with Δ(9)-tetrahydrocannabinol is already under clinical evaluation in patients with Huntington's disease to determine its potential as a disease-modifying therapy. The neuroprotective properties of CBD do not appear to be exerted by the activation of key targets within the endocannabinoid system for plant-derived cannabinoids like Δ(9)-tetrahydrocannabinol, i.e. CB(1) and CB(2) receptors, as CBD has negligible activity at these cannabinoid receptors, although certain activity at the CB(2) receptor has been documented in specific pathological conditions (i.e. damage of immature brain). Within the endocannabinoid system, CBD has been shown to have an inhibitory effect on the inactivation of endocannabinoids (i.e. inhibition of FAAH enzyme), thereby enhancing the action of these endogenous molecules on cannabinoid receptors, which is also noted in certain pathological conditions. CBD acts not only through the endocannabinoid system, but also causes direct or indirect activation of metabotropic receptors for serotonin or adenosine, and can target nuclear receptors of the PPAR family and also ion channels. © 2012 The Authors.

    On the hospital wards in Finland, nurses generally reconstitute intravenous medicines, such as antibiotics, analgesics, and antiemetics prescribed by doctors. Medicine reconstitution is prone to many errors. Therefore, it is important to identify incorrect practices in the reconstitution of medicine to improve patient safety in hospitals. The aim of this study was to audit the compounding and reconstituting of intravenous medicines on hospital wards in a secondary-care hospital in Finland by using an assessment tool and microbiological testing for identifying issues posing patient safety risks. A hospital pharmacist conducted an external audit by using a validated 65-item assessment tool for safe-medicine compounding practices on 20 wards of the selected hospital. Also, three different microbiological samples were collected to assure the aseptics. Practices were evaluated using a four-point rating scale of "never performed," "rarely performed," "often performed," and "always performed," and were based on observation and interviews with nurses or ward pharmacists. In addition, glove-, settle plate-, and media fill-tests were collected. Associations between microbial sample results and audit-tool results were discussed. Altogether, only six out of the 65 items were fully implemented in all wards; these were related to logistic practices and quality assurance. More than half of the wards used incorrect practices ("rarely performed" or "never performed") for five items. Most of these obviated practices related to aseptic practices. All media-fill tests were clean but the number of colony forming units in glove samples and settle- plate samples varied from 0 to >100. More contamination was found in wards where environmental conditions were inadequate or the use of gloves was incorrect. Compounding practices were [mostly] quite well adapted, but the aseptic practices needed improvement. Attention should have been directed particularly to good aseptic techniques and

    To describe medications that older adults in hospice with cancer, dementia, debility, heart disease, and lung disease take during the last week of life. Retrospective cross-sectional study. Nationally representative sample of 695 U.S. hospices in the 2007 National Home and Hospice Care Survey. Individuals aged 65 and older with a primary diagnosis of cancer (49%), dementia (12%), debility (14%), heart disease (16%), or lung disease (10%) who received end-of-life care during their last week of life (N = 2,623). Medication data were obtained from hospice staff, who were asked, "What are the names of all the medications and drugs the patient was taking 7 days prior to and on the day of his or her death while in hospice? Please include any standing, routine, or PRN medications." The unweighted survey response rate was 71%. The average number of medications taken was 10.2. The most common therapeutic classes were analgesics (98%); antiemetic and antivertigo medications (78%); anxiolytics, sedatives, and hypnotics (76%); anticonvulsants (71%); and laxatives (53%). Approximately one-quarter of the individuals took proton pump inhibitors, anticoagulants, and antidepressants, and fewer than 20% took antacids and antibiotics. A smaller percentage of individuals with dementia and debility than of those with cancer took opioid analgesics. Individuals with heart disease were more likely than individuals in the other clinical cohorts to take diuretics, and those with lung disease were more likely than those in the other clinical cohorts to take bronchodilators. A higher percentage of individuals with dementia and with debility than with cancer and lung disease took antidepressants. People continue to receive disease-focused therapies at the end of life rather than therapies exclusively for palliation of symptoms, suggesting that treatments may vary according to the person's primary diagnosis. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics

    Multimodal analgesia has been effectively used in postoperative pain control. Tramadol can be considered "multimodal" because it has two main mechanisms of action, an opioid agonist and a reuptake inhibitor of norepinephrine and serotonin. Tramadol is not as commonly used as morphine due to the increased incidence of postoperative nausea and vomiting (PONV). As metoclopramide is an antiemetic and an analgesic, it was hypothesized that when added to reduce PONV, metoclopromide may enhance the multimodal feature of tramadol by the analgesic property of metoclopramide. Therefore, the effectiveness of postoperative patient-controlled analgesia (PCA) with morphine was compared against PCA with combination of tramadol and metoclopramide. A prospective, randomized, double blind clinical trial. Academic pain service of a university hospital. Sixty patients undergoing elective total knee arthroplasty with general anesthesia. Sixty patients were randomly divided into Group M and Group T. In a double-blinded fashion, Group M received intraoperative 0.2 mg/kg morphine and postoperative PCA with 1 mg morphine per bolus, whereas Group T received intraoperative tramadol 2.5 mg/kg and postoperative PCA with 20 mg tramadol plus 1 mg metoclopramide per bolus. Lockout interval was 5 minutes in both groups. Pain scale, satisfaction rate, analgesic consumption, PCA demand, and side effects were recorded by a blind investigator. These two groups displayed no statistically significant difference between the items and variables evaluated. This combination provides analgesia equivalent to that of morphine and can be used as an alternative to morphine PCA. Wiley Periodicals, Inc.

    Full Text Available Pete Anderson, Patricia Wells, Theresa Lazarte, Laura Gore, Laura Salvador, Maritza Salazar-AbshireMD Anderson Cancer Center, Pediatrics, Houston TX, USAAbstract: Current osteosarcoma chemotherapy is “standard” (doxorubicin, cisplatin, high-dose methotrexate ± ifosfamide-mesna, and etoposide ± mifamurtide, but current regimens have many short-term, medium-term, and long-term side effects. Generally 12–15 cycles of chemotherapy are given in the hospital over 7–10 months. Even in the absence of new research protocols, improvement in quality of life is now possible, with all osteosarcoma chemotherapy agents now being able to be administered in the outpatient setting. Outpatient chemotherapy is not only less expensive, but in the adolescent and young adult population can result in better quality of life for some. In this paper, we share information to help reduce the frequency of hospitalization and review some tools and strategies to facilitate communication when providing outpatient chemotherapy, family-centered care, and information/education. These include antiemetics with both longer-acting 5HT antagonists and aprepitant, outpatient chemotherapy guidelines, and a 5-week editable calendar that is part of our electronic medical record. Sharing information on absolute lymphocyte count recovery is another means of maintaining hope and increasing understanding of the prognosis of osteosarcoma. Finally, this paper shares an advanced directive/palliative care “checklist” of issues for patients and caregivers to consider at end of life, ie, when “cure of cancer is not the answer”. In summary, better communication at all stages of osteosarcoma care can help reduce hospitalization, improve quality of life, and maintain hope in the adolescent and young adult population with osteosarcoma.Keywords: family-centered care, adolescent and young adult, flash drives, chemotherapy calendars, outpatient, osteosarcoma, chemotherapy

    The economic burden of metastatic pancreatic cancer (mPC) is substantial while treatment options are limited. Little is known about the treatment patterns and healthcare costs among mPC patients who initiated first-line gemcitabine plus nanoparticle albumin-bound paclitaxel (nab-P + G) and FOLFIRINOX. The MarketScan® claims databases were used to identify adults with ≥2 claims for pancreatic cancer, 1 claim for a secondary malignancy, completed ≥1 cycle of nab-P + G or FOLFIRINOX during 4/1/2013 and 3/31/2015, and had continuous plan enrollment for ≥6 months pre- and 3 months after the first-line treatment. Duration of therapy, per patient per month (PPPM) costs of total healthcare, mPC-related treatment, and supportive care were measured during first-line therapy. 550 mPC patients met selection criteria (nab-P + G, n = 294; FOLFIRINOX, n = 256). There was no difference in duration of therapy (p = 0.60) between nab-P + G and FOLFIRINOX. Compared with FOLFIRINOX, patients with nab-P + G had higher chemotherapy drug costs but lower treatment administration costs and supportive care costs (all p < 0.01). Patients treated with nab-P + G (vs FOLFIRINOX) had similar treatment duration but lower costs of outpatient prescriptions, treatment administration and supportive care. Lower supportive care costs in the nab-P + G cohort were mainly driven by lower utilization of pegfilgrastim and anti-emetics.

    Vomiting is a common side effect of cancer chemotherapy and many drug treatments and diseases. In animal studies, the measurement of vomiting usually requires direct observation, which is time consuming and often lacks temporal precision. Musk shrews have been used to study the neurobiology of emesis and have a rapid emetic episode (∼1 s for a sequence of retching and expulsion). The aim of the current study was to develop a method to automatically detect and characterize emetic episodes induced by the cancer chemotherapy agent cisplatin. The body contour in each video frame was tracked and normalized to a parameterized shape basis. The tracked shape was projected to a feature space that maximized the shape variations in the consecutive frames during retching. The resulting one dimensional projection was sufficient to detect most emetic episodes in the acute (peak at 2h) and delayed (peak at 54 h) phases after cisplatin treatment. Emetic episodes were relatively invariant in the number of retches (∼6.2), duration (∼1.2s), inter-retch interval (∼198 ms), and amplitude during the 72 h after cisplatin treatment. This approach should open a new vista into emesis research to permit tracking and analysis of emesis in a small animal model and facilitate the development of new antiemetic therapies. These results also yield a better understanding of the brain's central pattern generator for emesis and indicate that the retching response in the musk shrew (at ∼5.4 Hz) is the fastest ever recorded in a free-moving animal.

    Full Text Available Paul Glare, Jeanna Miller, Tanya Nikolova, Roma TickooPain and Palliative Care Service, Department of Medicine, Memorial Sloan-Kettering Cancer Center, New York, NY, USAAbstract: Nausea and vomiting are portrayed in the specialist palliative care literature as common and distressing symptoms affecting the majority of patients with advanced cancer and other life-limiting illnesses. However, recent surveys indicate that these symptoms may be less common and bothersome than has previously been reported. The standard palliative care approach to the assessment and treatment of nausea and vomiting is based on determining the cause and then relating this back to the “emetic pathway” before prescribing drugs such as dopamine antagonists, antihistamines, and anticholinergic agents which block neurotransmitters at different sites along the pathway. However, the evidence base for the effectiveness of this approach is meager, and may be in part because relevance of the neuropharmacology of the emetic pathway to palliative care patients is limited. Many palliative care patients are over the age of 65 years, making these agents difficult to use. Greater awareness of drug interactions and QTc prolongation are emerging concerns for all age groups. The selective serotonin receptor antagonists are the safest antiemetics, but are not used first-line in many countries because there is very little scientific rationale or clinical evidence to support their use outside the licensed indications. Cannabinoids may have an increasing role. Advances in interventional gastroenterology are increasing the options for nonpharmacological management. Despite these emerging issues, the approach to nausea and vomiting developed within palliative medicine over the past 40 years remains relevant. It advocates careful clinical evaluation of the symptom and the person suffering it, and an understanding of the clinical pharmacology of medicines that are available for palliating

    The role of serotonin receptors have been implicated in various types of experimentally induced seizures. Ondansetron is a highly selective 5-hydroxytryptamine 3 (5-HT(3)) receptor antagonist used as antiemetic agent for chemotherapy-, and radiotherapy-induced nausea and vomiting. The present study was carried out to examine the effect of ondansetron on electroshock, pentylenetetrazole (PTZ)-induced seizures and cognitive functions in mice. Ondansetron was administered intraperitoneally (i.p.) at doses of 0.5, 1.0 and 2.0 mg/kg (single dose) to observe its effect on the increasing current electroshock seizure (ICES) test and PTZ-induced seizure test. In addition, a chronic study (21 days) was also performed to assess the effects of ondansetron on electroshock-induced convulsions and cognitive functions. The effect on cognition was assessed by elevated plus maze and passive avoidance paradigms. Phenytoin (25 mg/kg, i.p.) was used as a standard anticonvulsant drug and piracetam (200 mg/kg) was administered as a standard nootropic drug. The results were compared with an acute study, wherein it was found that the administration of ondansetron (1.0 and 2.0 mg/kg) significantly raised the seizure-threshold current as compared to control group in the ICES test. Similar results were observed after chronic administration of ondansetron. In PTZ test, ondansetron in all the three tested doses failed to show protective effect against PTZ-induced seizure test. Administration of ondansetron for 21 days significantly decreased the transfer latency (TL) and prolonged the step-down latency (SDL). The results of present study suggest the anticonvulsant and memory-enhancing effect of ondansetron in mice.

    Purpose: To report long-term data from a prospective trial of subcutaneous (s.c.) amifostine in patients who received chemoradiotherapy for squamous cell carcinoma of the head and neck (SCCHN). Methods and Materials: Patients ≥18 years of age with previously untreated Stage III/IV SCCHN received fractionated radiotherapy, 1.8-2.0 Gy/day, 5 days per week, to a total dose of 70-72 Gy, plus weekly paclitaxel (40 mg/m 2 ) and carboplatin (100 mg/m 2 ) administered intravenously (i.v.) for 6 weeks. All patients received 500 mg s.c. amifostine 30-60 min before radiotherapy with antihistamine and antiemetic prophylaxis. Results: Twenty patients were evaluable (median age, 55 years). The incidence of Grade 2 xerostomia was 42% and 29% at 12 and 18 months, respectively; there were no reports of Grade ≥3 xerostomia. Grade ≥3 mucositis occurred in 30% of patients, with median time to resolution of 12.5 weeks (range, 5-17 weeks). Survival estimates at 1 and 2 years were 95% and 71%, respectively. All patients experienced Grade 2 weight loss; 7 patients (35%) experienced Grade ≤2 nausea/vomiting. There were no reports of Grade ≥3 amifostine-related adverse events. Conclusions: Subcutaneous amifostine was well tolerated by patients receiving chemoradiotherapy for SCCHN, with lower rates of nausea/vomiting than reported in trials with i.v. amifostine. Xerostomia and mucositis rates were similar to those reported in trials with i.v. amifostine

    Orally disintegrating tablets (ODT) are gaining attractiveness over conventional tablets especially for patients having difficulty in swallowing such as pediatric, geriatric, bedridden and disable patients. ODT technologies render the tablets disintegrate in the mouth without chewing or additional water intake. So far there have been many patents for ODT, but only few publications are dealing with this dosage form. The aim of the present study was to formulate metoclopramide in ODT with sufficient mechanical strength and fast disintegration from bases prepared by both spray (SD) and freeze drying (FD) techniques. Different disintegration accelerators (DA) were utilized to prepare proper ODT using various super-disintegrants (Ac-Di-Sol, Kollidon and Sodium Starch glycolate), a volatilizing solvent (ethanol) and an amino acid (glycine). Metoclopramide, an antiemetic medication, was used a model drug in the formulated ODT. It was noted that the disintegration of ODT depends on utilization of DA in both SD and FD techniques to prepare tablet bases for ODT and so many other factors such as drying processes. The good disintegration property of the prepared tablets was related to the excellent wettability of the ingredients after being subjected to the drying processes. Results also showed that the addition of DA to the tablet bases before drying process results in lengthening of the disintegration time in comparison to their addition to the tablet bases after the drying process. Those findings be utilized for many drugs and they may be considered versatile in their applications. Also, the disintegration of the ODT in the buccal cavity may favor fast absorption via the mucus membrane in the oral cavity. (author)

Clinical management of MBO requires a specific and individualized approach that is based on disease prognosis and the objectives of care. The global prevalence of MBO is estimated to be 3% to 15% of cancer patients. Surgery should always be considered for patients in the initial stages of the disease with a preserved general status and a single level of occlusion. Less invasive approaches such as duodenal or colonic stenting should be considered when surgery is contraindicated in obstructions at the single level. The priority of care for inoperable and consolidated MBO is to control symptoms and promote the maximum level of comfort possible. The spontaneous resolution of an inoperable obstructive process is observed in more than one third of patients. The mean survival is of no longer than 4–5 weeks in patients with consolidated MBO. Polymodal medical treatment based on a combination of glucocorticoids, strong opioids, antiemetics, and antisecretory drugs achieves very high symptomatic control. This review focuses on the epidemiological aspects, diagnosis, surgical criteria, medical management, and factors influencing the spontaneous resolution of MBO in advanced cancer patients.Keywords: malignant bowel obstruction, cancer, intestinal obstruction, bowel occlusion

Salesi", Ancona, Italy Abstract: Acute gastroenteritis, characterized by the onset of diarrhea with or without vomiting, continues to be a major cause of morbidity and mortality in children in mostly resource-constrained nations. Although generally a mild and self-limiting disease, gastroenteritis is one of the most common causes of hospitalization and is associated with a substantial disease burden. Worldwide, up to 40% of children aged less than 5 years with diarrhea are hospitalized with rotavirus. Also, some microorganisms have been found predominantly in resource-constrained nations, including Shigella spp, Vibrio cholerae, and the protozoan infections. Prevention remains essential, and the rotavirus vaccines have demonstrated good safety and efficacy profiles in large clinical trials. Because dehydration is the major complication associated with gastroenteritis, appropriate fluid management (oral or intravenous is an effective and safe strategy for rehydration. Continuation of breastfeeding is strongly recommended. New treatments such as antiemetics (ondansetron, some antidiarrheal agents (racecadotril, and chemotherapeutic agents are often proposed, but not yet universally recommended. Probiotics, also known as “food supplement,” seem to improve intestinal microbial balance, reducing the duration and the severity of acute infectious diarrhea. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition and the European Society of Paediatric Infectious Diseases guidelines make a stronger recommendation for the use of probiotics for the management of acute gastroenteritis, particularly those with documented efficacy such as Lactobacillus rhamnosus GG, Lactobacillus reuteri, and Saccharomyces boulardii.

    Full Text Available Background and Aims: Post-operative vomiting (POV in children remains a significant clinical problem. This prospective study aims to investigate the applicability of well-established adult early post-operative nausea and vomiting (PONV risk factors on paediatric POV after adenotonsillectomies under regulated anaesthetic conditions. Methods: After Institutional Review Board approval, 213 children aged 3–10-year-old were enrolled. The participants had pre-operative questionnaires completed, followed protocolised anaesthetic plans and had saliva analysed for cotinine. The primary outcomes were POV as correlated with age, gender, family or personal history of PONV, motion sickness history, opioid use, surgical time, anaesthetic time and environmental tobacco smoke (ETS exposure, as assessed by cotinine levels and questionnaire reports. Data on analgesics, antiemetics and POV incidence before post-anaesthesia care unit discharge were collected. Statistical analysis was done through multiple logistic regression. Results: A total of 200 patients finalised the study. Early POV occurred in 32%. Family history of PONV (odds ratio [OR] = 5.3, P < 0.01 and motion sickness history (OR = 4.4, P = 0.02 were highly significant risk factors. Age reached borderline statistical significance (OR = 1.4, P = 0.05. None of the other factors reached statistical significance. Conclusion: Early POV occurs frequently in paediatric patients undergoing adenotonsillectomies. In this paediatric-aged group, the incidence of POV was affected by the family history of PONV, and history of motion sickness. Age, female gender, opioid use, surgical and anaesthetic times did not affect the incidence of POV. ETS exposure, as assessed by cotinine levels and questionnaire reports, had no protective effect on early paediatric POV.

    Cannabidiol (CBD) is a phytocannabinoid with therapeutic properties for numerous disorders exerted through molecular mechanisms that are yet to be completely identified. CBD acts in some experimental models as an anti-inflammatory, anticonvulsant, anti-oxidant, anti-emetic, anxiolytic and antipsychotic agent, and is therefore a potential medicine for the treatment of neuroinflammation, epilepsy, oxidative injury, vomiting and nausea, anxiety and schizophrenia, respectively. The neuroprotective potential of CBD, based on the combination of its anti-inflammatory and anti-oxidant properties, is of particular interest and is presently under intense preclinical research in numerous neurodegenerative disorders. In fact, CBD combined with Δ9-tetrahydrocannabinol is already under clinical evaluation in patients with Huntington's disease to determine its potential as a disease-modifying therapy. The neuroprotective properties of CBD do not appear to be exerted by the activation of key targets within the endocannabinoid system for plant-derived cannabinoids like Δ9-tetrahydrocannabinol, i.e. CB1 and CB2 receptors, as CBD has negligible activity at these cannabinoid receptors, although certain activity at the CB2 receptor has been documented in specific pathological conditions (i.e. damage of immature brain). Within the endocannabinoid system, CBD has been shown to have an inhibitory effect on the inactivation of endocannabinoids (i.e. inhibition of FAAH enzyme), thereby enhancing the action of these endogenous molecules on cannabinoid receptors, which is also noted in certain pathological conditions. CBD acts not only through the endocannabinoid system, but also causes direct or indirect activation of metabotropic receptors for serotonin or adenosine, and can target nuclear receptors of the PPAR family and also ion channels.

    The aim of this study was to analyze prescription patterns and the cost of migraine treatments in general practices (GPs) and neurological practices (NPs) in Germany. This study included 43,149 patients treated in GPs and 13,674 patients treated in NPs who were diagnosed with migraine in 2015. Ten different families of migraine therapy were included in the analysis: triptans, analgesics, anti-emetics, beta-blockers, antivertigo products, gastroprokinetics, anti-epileptics, calcium channel blockers, tricyclic antidepressants, and other medications (all other classes used in the treatment of migraine including homeopathic medications). The share of migraine therapies and their costs were estimated for GPs and NPs. The mean age was 44.4 years in GPs and 44.1 years in NPs. Triptans and analgesics were the 2 most commonly prescribed families of drugs in all patients and in the 9 specific subgroups. Interestingly, triptans were more commonly prescribed in NPs than in GPs (30.9% to 55.0% vs. 30.0% to 44.7%), whereas analgesics were less frequently given in NPs than in GPs (11.5% to 17.2% vs. 35.3% to 42.4%). Finally, the share of patients who received no therapy was higher in NPs than in GPs (33.9% to 58.4% vs. 27.5% to 37.9%). The annual cost per patient was €66.04 in GPs and €94.71 in NPs. Finally, the annual cost per patient increased with age and was higher in women and in individuals with private health insurance coverage than in men and individuals with public health insurance coverage. Triptans and analgesics were the 2 most commonly prescribed drugs for the treatment of migraine. Furthermore, approximately 30% to 40% of patients did not receive any therapy. Finally, the annual cost per patient was higher in NPs than in GPs. © 2016 World Institute of Pain.

    At present there is no established therapy for treating patients with hereditary hemorrhagic telangiectasia (HHT) and symptomatic hepatic involvement. We present the results of a prospective study with 15 consecutive patients who were treated with staged hepatic artery embolization (HAE). Branches of the hepatic artery were selectively catheterized and embolized in stages using polyvinyl alcohol particles (PVA) and platinum microcoils or steel macrocoils. Prophylactic antibiotics, analgesics and anti-emetics were administered after every embolization. Clinical symptomatology and cardiac output were assessed before and after therapy as well as at the end of follow-up (median 28 months; range 10-136 months). Five patients had abdominal pain and four patients had symptoms of portal hypertension. The cardiac output was raised in all patients, with cardiac failure being present in 11 patients. After treatment, pain resolved in all five patients, and portal hypertension improved in two of the four patients. The mean cardiac output decreased significantly (P<0.001) from 12.57{+-}3.27 l/min pre-treatment to 8.36{+-}2.60 l/min at the end of follow-up. Symptoms arising from cardiac failure resolved or improved markedly in all but one patient. Cholangitis and/or cholecystitis occurred in three patients of whom two required a cholecystectomy. One patient with pre-existent hepatic cirrhosis died as a complication of the procedure. Staged HAE yields long-term relief of clinical symptoms in patients with HHT and hepatic involvement. Patients with pre-existing hepatic cirrhosis may be poor candidates for HAE. (orig.)

    Rhizoma Pinelliae is the dried tuber of Pinellia ternata (Thunb.) Breit. Modern pharmacological studies have shown that Rhizoma Pinelliae has antitussive, antiemetic, glandular secretion inhibiting and antitumor effects. To optimize the processing technology of Rhizoma Pinelliae Praeparatum, and to study its anti-tumor effect. Orthogonal design method was applied to analyze the effects of factors such as licorice concentration volume, soaking time and processing temperature on processing technology of Rhizoma Pinelliae Praeparatum; MTT assay and flow cytometry were used to determine the inhibitory effect of Rhizoma Pinelliae Praeparatum on Bel-7402 cells. During the processing of Rhizoma Pinelliae Praeparatum, the size of influence of licorice concentration volume, soaking time and processing temperature on processing results of Rhizoma Pinelliae was: B>C>A in descending order, i.e. soaking time>processing temperature>licorice concentration volume, different concentrations of Rhizoma Pinelliae Praeparatum ethanol extracts could all exert inhibitory effect on the growth and proliferation of Bel-7402 cells, and with the increase of drug concentration and the extension of culture time, the cell proliferation inhibitory effect of Rhizoma Pinelliae Praeparatum ethanol extract became more and more evident. Apoptotic rate of 1.5 mg/ml Rhizoma Pinelliae Praeparatum ethanol extract group reached 13.53%, the difference was extremely significant compared with the control group. In conclusion the factor most influential to the processing technology of Rhizoma Pinelliae Praeparatum was soaking time, followed by processing temperature, the factor least influential was licorice concentration volume. Rhizoma Pinelliae Praeparatum has inhibitory effect on growth and proliferation of Bel-7402 cells.

Mothers of children with cardiac defects were interviewed at the echocardiography centre. Variables included were A- Muscular plus Vascular defects; B- Valvular defects; C-Pericardial effusion; D- Dextrocardia and E- Congestive cardiac failure. History of children for sore throat followed by joint pains; history of mothers for drug intake (antihypertensive, antipyretic, anti-emetic, hypoglycaemic) as well as chronic diseases (diabetes mellitus, hypertension, anaemia) during pregnancy were surveyed. Parity of mothers, their cousin marriages, and family socio-economic status was also inquired. The results were tabulated, analyzed and finally subjected to suitable test of significant (SR of proportion) to find out statistical significant if any. Results: It was found that out of 150 patients, 76 (50.66%) were suffering from Cardiac muscular and Vascular defects, 61 (40.66%) Valvular defects, 7 (4.66%) Pericardial effusion, 2 (1.33%) Dextrocardia and 4 (2.66%) from Congestive Cardiac Failure. According to age, 54 (36%) were from birth to 3 years of age and 51 (34%) from 10 to 12 years. There was history of Rheumatic fever among 45 (30%) children. There were 106 (70.6%) children from lower socio-economic class and 79 (52.6%) parents had history of cousin marriages. Conclusion: Frequency of cardiac defects was more in children of male sex, lower socio-economic group, from birth to three years age and children from primipara mothers in our specified locality. Rheumatic fever, cousin's marriage, and prescribed drugs intake during pregnancy (for metabolic and hormonal disorders) were other contributors to cardiac defects. (author)

    Heatstroke is a life-threating emergency in dogs. The aim of this retrospective study was to analyse the sources of heat stroke in dogs, predisposing and prognostic factors, results of physical examination and clinical pathology as well as the course of this condition and appropriate treatment. Patient histories of 12 dogs diagnosed with heat stroke over a 5.5-year period were analysed retrospectively. Normality was tested using the Kolmogrow-Smirnow Test and analysed using T-tests, the Chi-square test and the Mann-Whitney U-test. P-values Heat stroke occurred most frequently during summer, particularly in the afternoon. The most common cause of heat stroke was heat exposition in a car. Brachycephalic breeds were overrepresented. The most common clinical signs were polypnoea, tachycardia, hyperthermia and depression to prostration as well as gastrointestinal and neurological symptoms. Clinical pathology results included haemoconcentration, thrombocytopenia, hyperkalemia, prolonged activated partial thromboplastin time and azotemia. Therapies employed included oxygen application, cooling, fluid therapy and administration of gastrointestinal protectants, antiemetics and antibiotics. Duration of hospitalization was 1-6 days. The overall mortality rate was 50%. Most of the non-survivors died or were euthanized within 24-48 hours after presentation. All animals remaining alive after 3 days survived and could be discharged from hospital. Heat stroke is a life-threating condition, which can lead to shock, sepsis, coagulation disorders and multiorgan failure. Early recognition and appropriate treatment are important factors for a positive outcome. Furthermore, intensive monitoring and rapid therapy adaption as required are pivotal.

    Full Text Available Cannabis is one of the oldest psychotropic drugs known to humanity. The paper assesses the current knowledge on the cannabis, including the mechanisms of action and the therapeutic potential of cannabinoids. Three varieties of Cannabis plant are recognised: Cannabis sativa, Cannabis indica, and Cannabis ruderalis. The variety indica is used predominantly to obtain the drugs. Cannabis herb is usually named marijuana, while the cannabis oleoresin secreted by the glandular hairs found mainly on the flowering or fruiting tops of the plant is known as hashish. More than 400 known chemicals are present in cannabis, at least 70 of which are called cannabinoids. The major psychoactive constituent in cannabis is delta-9-tetrahydrocannabinol (Δ9-THC. It is now recognized that there are three types of cannabinoids: natural (phytocannabinoids, endogenous cannabinoids, and synthetic cannabioids. Cannabinoids exert their actions by binding to specific membrane protein, the cannabinoid receptor. To date, two subtypes of cannabinoid receptors, named cannabinoid-1 (CB1, most abundantly expressed in the central nervous system and cannabinoid-2 (CB2 receptors, found predominantly in peripheral tissues with immune functions have been cloned. Therefore, the concept of endogenous cannabinoid system (endocannabinoid system, SEC has been developed. Based on the current scientific evidence, there are several effects of cannabinoids with potential therapeutic use: antiemetic, analgesic in cancerous pains, and chronic neuropathic pain, in multiple sclerosis or spinal cord injuries. Cannabis consume can result in a state of drug dependency and cannabis withdrawal has been included in DSM-V. Cannabis plant remains controversial in the twenty-first century and the potential therapeutic of specific cannabinoid compounds and medical marijuana remains under active medical research.

    In the United States, hyperemesis gravidarum is the most common cause of hospitalization during the first half of pregnancy and is second only to preterm labor for hospitalizations in pregnancy overall. In approximately 0.3-3% of pregnancies, hyperemesis gravidarum is prevalent and this percentage varies on account of different diagnostic criteria and ethnic variation in study populations. Despite extensive research in this field, the mechanism of the disease is largely unknown. Although cases of mortality are rare, hyperemesis gravidarum has been associated with both maternal and fetal morbidity. The current mainstay of treatment relies heavily on supportive measures until improvement of symptoms as part of the natural course of hyperemesis gravidarum, which occurs with progression of gestational age. However, studies have reported that severe, refractory disease manifestations have led to serious adverse outcomes and to termination of pregnancies. Despite extensive research in the field, the pathogenesis of hyperemesis gravidarum remains unknown. Recent literature points to a genetic predisposition in addition to previously studied factors such as infectious, psychiatric, and hormonal contributions. Maternal morbidity is common and includes psychological effects, financial burden, clinical complications from nutritional deficiencies, gastrointestinal trauma, and in rare cases, neurological damage. The effect of hyperemesis gravidarum on neonatal health is still debated in literature with conflicting results regarding outcomes of birth weight and prematurity. Available therapy options remain largely unchanged in the past several decades and focus on parenteral antiemetic medications, electrolyte repletion, and nutritional support. Most studies of therapeutic options do not consist of randomized control studies and cross-study analysis is difficult due to considerable variation of diagnostic criteria. Key Messages: Hyperemesis gravidarum carries a significant

    The purpose of this study is to determine the frequency of emotional, behavioral, and learning disorders in children exposed in utero to hyperemesis gravidarum (HG) and to identify prognostic factors for these disorders. Neurodevelopmental outcomes of 312 children from 203 mothers with HG were compared to neurodevelopmental outcomes from 169 children from 89 unaffected mothers. Then the clinical profiles of patients with HG and a normal child outcome were compared to the clinical profiles of patients with HG and a child with neurodevelopmental delay to identify prognostic factors. Binary responses were analyzed using either a Chi-square or Fisher Exact test and continuous responses were analyzed using a t-test. Children exposed in utero to HG have a 3.28-fold increase in odds of a neurodevelopmental diagnosis including attention disorders, learning delay, sensory disorders, and speech and language delay (P<0.0005). Among characteristics of HG pregnancies, only early onset of symptoms (prior to 5 weeks gestation) was significantly linked to neurodevelopmental delay. We found no evidence for increased risk of 13 emotional, behavioral, and learning disorders, including autism, intellectual impairment, and obsessive-compulsive disorder. However, the study was not sufficiently powered to detect rare conditions. Medications, treatments, and preterm birth were not associated with an increased risk for neurodevelopmental delay. Women with HG are at a significantly increased risk of having a child with neurodevelopmental delay. Common antiemetic treatments were not linked to neurodevelopmental delay, but early symptoms may play a role. There is an urgent need to address whether aggressive treatment that includes vitamin and nutrient supplementation in women with early symptoms of severe nausea of pregnancy decreases the risk of neurodevelopmental delay.

    Full Text Available Abstract Background This study was designed to evaluate the utility of transdermal fentanyl (TDF, Durogesic® for the treatment of pain due to osteoarthritis (OA of the knee or hip, which was not adequately controlled by non-opioid analgesics or weak opioids. The second part of the trial, investigating TDF in patients with rheumatoid arthritis (RA is reported separately. Methods Current analgesia was optimised during a 1-week run-in. Patients then received 28 days treatment with TDF starting at 25 μg/hr, with the option to increase the dose until adequate pain control was achieved. Metoclopramide was taken during the first week and then as needed. Results Of the 159 patients recruited, 75 with OA knee and 44 with OA hip completed the treatment phase, 30 knee and 18 hip patients entered the one-week taper-off phase. The most frequently used maximum dose of TDF was 25 μg/hr. The number of patients with adequate pain control increased during the run-in period from 4% to 27%, and further increased during TDF treatment to 88% on day 28. From baseline to endpoint, there were significant reductions in pain (p Conclusion TDF significantly increased pain control, and improved functioning and quality of life. Metoclopramide appeared to be of limited value in preventing nausea and vomiting; more effective anti-emetic treatment may enable more people to benefit from strong opioids such as TDF. This study suggests that four weeks is a reasonable period to test the benefit of adding TDF to improve pain control in OA patients and that discontinuing therapy in cases of limited benefit creates no major obstacles.

    Nausea and/or vomiting are aversive gastrointestinal (GI) symptoms. Nausea and vomiting manifest unconditionally after a nauseogenic experience. However, there is correlative, quasiexperimental and experimental evidence that nausea and vomiting can also be learned via classical (Pavlovian) conditioning and might occur in anticipation of the nauseogenic event. Classical conditioning of nausea can develop with chemotherapy in cancer patients. Initially, nausea and vomiting occur during and after the administration of cytotoxic drugs (post-treatment nausea and vomiting) as unconditioned responses (UR). In addition, 20%-30% of cancer patients receiving chemotherapy report these side effects, despite antiemetic medication, when being re-exposed to the stimuli that usually signal the chemotherapy session and its drug infusion. These symptoms are called anticipatory nausea (AN) and/or anticipatory vomiting (ANV) and are explained by classical conditioning. Moreover, there is recent evidence for the assumption that post-chemotherapy nausea is at least partly influenced by learning. After summarizing the relevant assumptions of the conditioning model, revealing that a context can become a conditioned stimulus (CS), the present paper summarizes data that nausea and/or vomiting is acquired by classical conditioning and, consequently, may be alleviated by conditioning techniques. Our own research has focussed on two aspects and is emphasized here. First, a conditioned nausea model was established in healthy humans using body rotation as the nausea-inducing treatment. The validity of this motion-sickness model to examine conditioning mechanisms in the acquisition and alleviation of conditioned nausea and associated endocrine and immunological responses is summarized. Results from the rotation-induced motion sickness model showed that gender is an important moderator variable to be considered in further studies. This paper concludes with a review of the application of the

    Full Text Available Abstract Introduction Certain Staphylococcus aureus strains produce Panton-Valentine leukocidin, a toxin that lyses white blood cells causing extensive tissue necrosis and chronic, recurrent or severe infection. This report documents a confirmed case of methicillin-sensitive Staphylococcus aureus strain harboring Panton-Valentine leukocidin genes from Trinidad and Tobago. To the best of our knowledge, this is the first time that such a case has been identified and reported from this country. Case presentation A 13-year-old Trinidadian boy of African descent presented with upper respiratory symptoms and gastroenteritis-like syptoms. About two weeks later he was re-admitted to our hospital complaining of pain and weakness affecting his left leg, where he had received an intramuscular injection of an anti-emetic drug. He deteriorated and developed septic arthritis, necrotizing fasciitis and septic shock with acute respiratory distress syndrome, leading to death within 48 hours of admission despite intensive care treatment. The infection was caused by S. aureus. Bacterial isolates from specimens recovered from our patient before and after his death were analyzed using microarray DNA analysis and spa typing, and the results revealed that the S. aureus isolates belonged to clonal complex 8, were methicillin-susceptible and positive for Panton-Valentine leukocidin. An autopsy revealed multi-organ failure and histological tissue stains of several organs were also performed and showed involvement of his lungs, liver, kidneys and thymus, which showed Hassal's corpuscles. Conclusion Rapid identification of Panton-Valentine leukocidin in methicillin-sensitive S. aureus isolates causing severe infections is necessary so as not to miss their potentially devastating consequences. Early feedback from the clinical laboratories is crucial.

  8. Cannabidiol in Humans—The Quest for Therapeutic Targets

    2012-05-01

    Full Text Available Cannabidiol (CBD, a major phytocannabinoid constituent of cannabis, is attracting growing attention in medicine for its anxiolytic, antipsychotic, antiemetic and anti-inflammatory properties. However, up to this point, a comprehensive literature review of the effects of CBD in humans is lacking. The aim of the present systematic review is to examine the randomized and crossover studies that administered CBD to healthy controls and to clinical patients. A systematic search was performed in the electronic databases PubMed and EMBASE using the key word “cannabidiol”. Both monotherapy and combination studies (e.g., CBD + ∆9-THC were included. A total of 34 studies were identified: 16 of these were experimental studies, conducted in healthy subjects, and 18 were conducted in clinical populations, including multiple sclerosis (six studies, schizophrenia and bipolar mania (four studies, social anxiety disorder (two studies, neuropathic and cancer pain (two studies, cancer anorexia (one study, Huntington’s disease (one study, insomnia (one study, and epilepsy (one study. Experimental studies indicate that a high-dose of inhaled/intravenous CBD is required to inhibit the effects of a lower dose of ∆9-THC. Moreover, some experimental and clinical studies suggest that oral/oromucosal CBD may prolong and/or intensify ∆9-THC-induced effects, whereas others suggest that it may inhibit ∆9-THC-induced effects. Finally, preliminary clinical trials suggest that high-dose oral CBD (150–600 mg/d may exert a therapeutic effect for social anxiety disorder, insomnia and epilepsy, but also that it may cause mental sedation. Potential pharmacokinetic and pharmacodynamic explanations for these results are discussed.

    Morphine is the reference treatment for severe acute pain in an emergency department. The purpose of this study was to describe and analyse opioid-related ADRs (adverse drug reactions) in a large cohort of emergency department patients, and to identify predictive factors for those ADRs. In this prospective, observational, pharmaco-epidemiological international cohort study, all patients aged 18years or older who were treated with morphine were enrolled. The study was done in 23 emergency departments in the US and France. Baseline numerical rating scale score and initial and total doses of morphine titration were recorded. Logistic regression analysis was used to study the effects of demographic, clinical and medical history covariates on the occurrence of opioid-induced ADRs within 6h after treatment. A total of 1128 patients were included over 10months. Median baseline initial pain scores were 8/10 (7-10) versus 3/10 (1-4) after morphine administration. Median titration duration was 10min (IQR, 1-30). The occurrence of opioid-induced ADRs was 25% and 2% were serious. Patients experienced mainly nausea and drowsiness. Medical history of travel sickness (odds ratio [OR], 1.7; 95% confidence interval [CI], 1.01-2.86) and history of nausea or vomiting post morphine (OR, 3.86; 95% CI, 2.29-6.51) were independent predictors of morphine related ADRs. Serious morphine related ADRs are rare and unpredictable. Prophylactic antiemetic therapy could be proposed to patients with history of travel sickness and history of nausea or vomiting in a postoperative setting or after morphine administration.

    To describe the frequency of dose notification of antiinfectives for systemic use in clinical cases published in Revista Española de Anestesiología y Reanimación. Review of individualized clinical cases published in the sections «Clinical case» or «Letter to the Editor» of the above mentioned journal from year 2010 to 2012, and identification of the drugs and their therapeutic regimens cited in such publications, being dose notification the main variable. Drugs have been classified according to the Anatomical Therapeutic Chemical Classification System. One thousand one hundred and thirty-five drugs cited 1,317 times were identified in 167 articles describing the clinical pictures of 182 patients, 73 of the citations (5.6%) regarding to drugs belonging to group J (Antiinfectives for systemic use) which were divided into perioperative prophylaxis (n=15) and active treatment (n=58). Doses were scarcely notified for group J drugs as a whole (27.4%), but especially for active treatment (17.2%) compared to perioperative prophylaxis (66.7%), percentage which was similar to those more classical anesthetic drugs (fentanyl: 86.6%; remifentanil: 70.5%; sevoflurane: 78%; propofol: 79%; rocuronium:79.6%; cisatracurium: 68.4%) or even for antiemetics (ondansetron: 92.3%; dexamethasone: 84.6%). Quality of case reports could be improved by including dose notification for antiinfective agents. Copyright © 2013 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.

    2012-01-01

    Background Despite its high incidence among children under the age of five, little is known about the burden of pediatric gastroenteritis outside the medical setting. The objective of this study was to describe the burden of acute gastroenteritis among children residing in the United Arab Emirates, including those not receiving medical care. Methods A quantitative cross-sectional survey of 500 parents of children under 5 years of age who had suffered from acute gastroenteritis the preceding three months was conducted in the cities of Abu Dhabi and Al Ain. Data collected included respondent characteristics, disease symptoms, medical care sought, and parental expenditures and work loss. Data were analyzed using parametric and non-parametric statistical methods. Results Vomiting and diarrhea episodes lasted on average between 3 and 4 days. Overall, 87% of parents sought medical care for their children; 10% of these cases required hospitalization with an average length of stay of 2.6 days. When medical care was sought, the average parental cost per gastroenteritis episode was US$64, 4.5 times higher than with home care only (US$14). Nearly 60% of this difference was attributable to co-payments and medication use: 69% of children used oral rehydration solution, 68% antiemetics, 65% antibiotics and 64% antidiarrheals. Overall, 38 parents missed work per 100 gastroenteritis episodes for an average of 1.4 days. Conclusions Given its high incidence, pediatric gastroenteritis has an important financial and productivity impact on parents in the United Arab Emirates. To reduce this impact, efforts should be made both to prevent acute gastroenteritis and to optimize its treatment. PMID:22708988

    There are few studies in Spain on the use of activated charcoal (AC) in acute poisoning via the digestive tract, and more specifically on its protocol and adverse events following its administration. The aim of this article is to know the experience in the use of AC by doctors and nurses of the Spanish emergency services. Survey developed using Google Docs to health professionals in emergency services. Three hundred and sixty-four questionnaires were received, 52% of them from doctors. Catheterization prior to the use of AC in 74.5% of patients was performed, and did not use a catheter in 13%. The application of AC was considered correct in 37.4%, and overall it was used in 92.4% of cases. The lateral safety position was used in 46.2%, antiemetics in 86.5% and isolation of the airway in case of coma (GCS<8) in 60%. The most described adverse events were vomiting of AC (61%), epixtasis when the catheter was positioned (51.1%), and its incorrect positioning (36%). Inhaling vomit occurred in 11.8% and inhaling carbon in 4.7%. Seven point one percent stated that the adverse events had been life-threatening to patients. No relation was found between the protocol and serious or life-threatening adverse events, nor between these latter and clinical safety measures. The incidence of adverse events according to the information provided by professionals in this survey of clinical practice might be higher than the incidence found in the literature.

  13. Cannabinoid-Induced Hyperemesis: A Conundrum—From Clinical Recognition to Basic Science Mechanisms

    Nissar A. Darmani

    2010-07-01

    Full Text Available Cannabinoids are used clinically on a subacute basis as prophylactic agonist antiemetics for the prevention of nausea and vomiting caused by chemotherapeutics. Cannabinoids prevent vomiting by inhibition of release of emetic neurotransmitters via stimulation of presynaptic cannabinoid CB1 receptors. Cannabis-induced hyperemesis is a recently recognized syndrome associated with chronic cannabis use. It is characterized by repeated cyclical vomiting and learned compulsive hot water bathing behavior. Although considered rare, recent international publications of numerous case reports suggest the contrary. The syndrome appears to be a paradox and the pathophysiological mechanism(s underlying the induced vomiting remains unknown. Although some traditional hypotheses have already been proposed, the present review critically explores the basic science of these explanations in the clinical setting and provides more current mechanisms for the induced hyperemesis. These encompass: (1 pharmacokinetic factors such as long half-life, chronic exposure, lipid solubility, individual variation in metabolism/excretion leading to accumulation of emetogenic cannabinoid metabolites, and/or cannabinoid withdrawal; and (2 pharmacodynamic factors including switching of the efficacy of Δ9-THC from partial agonist to antagonist, differential interaction of Δ9-THC with Gs and Gi signal transduction proteins, CB1 receptor desensitization or downregulation, alterations in tissue concentrations of endocannabinoid agonists/inverse agonists, Δ9-THC-induced mobilization of emetogenic metabolites of the arachidonic acid cascade, brainstem versus enteric actions of Δ9-THC, and/or hypothermic versus hyperthermic actions of Δ9-THC. In addition, human and animal findings suggest that chronic exposure to cannabis may not be a prerequisite for the induction of vomiting but is required for the intensity of emesis.

    Breast reduction has traditionally been performed under general anesthesia with adjunct opioid use. However, opioids are associated with a wide variety of adverse effects, including nausea, vomiting, constipation, postoperative sedation, dizziness, and addiction. This study compares bilateral breast reduction using a multimodal opioid-free pain management regimen vs traditional general anesthesia with adjunct opioids. A total of 83 female patients were enrolled in this study. Group 1 includes a retrospective series of 39 patients that underwent breast reduction via general anesthesia with adjunct opioid use. This series was compared to 2 prospective groups of patients who did not receive opioids either preoperatively or intraoperatively. In group 2, twenty-six patients underwent surgery under intravenous sedation and local anesthesia. In group 3, eighteen patients underwent surgery with general anesthesia. All patients in groups 2 and 3 received preoperative gabapentin and celecoxib along with infiltration of local anesthetics during the operation and prior to discharge to the Post-Anesthesia Care Unit (PACU). Primary outcome measures included the duration of surgery, time from end of operation to discharge home, postoperative opioid and antiemetic use, and unplanned postoperative hospitalizations. When compared to group 1, groups 2 and 3 experienced a shorter time from end of operation to discharge home (P opioid use (P opioid-free bilateral breast reduction either under local or general anesthesia as an outpatient. This method resulted in significantly less morbidity, use of opioids postoperatively, as well as unplanned hospital admissions compared to "traditional" breast reduction under general anesthesia with the use of opioids. 3. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

    2005-11-01

    Most movement disorders, reflecting degenerative disorders, develop in a slowly progressive fashion. Some movement disorders, however, manifest with an acute onset. We wish to give an overview of the management and therapy of those acute-onset movement disorders.Drug-induced movement disorders are mainly caused by dopamine-receptor blockers (DRB) as used as antipsychotics (neuroleptics) and antiemetics. Acute dystonic reactions usually occur within the first four days of treatment. Typically, cranial pharyngeal and cervical muscles are affected. Anticholinergics produce a prompt relief. Akathisia is characterized by an often exceedingly bothersome feeling of restlessness and the inability to remain still. It is a common side effect of DRB and occurs within few days after their initiation. It subsides when DRB are ceased. Neuroleptic Malignant Syndrome is a rare, but life-threatening adverse reaction to DRB which may occur at any time during DRB application. It is characterised by hyperthermia, rigidity, reduced consciousness and autonomic failure. Therapeutically immediate DRB withdrawal is crucial. Additional dantrolene or bromocriptine application together with symptomatic treatment may be necessary. Paroxysmal dyskinesias are childhood onset disorders characterised by dystonic postures, chorea, athetosis and ballism occurring at irregular intervals. In Paroxysmal Kinesigenic Dyskinesia they are triggered by rapid movements, startle reactions or hyperventilation. They last up to 5 minutes, occur up to 100 times per day and are highly sensitive to anticonvulsants. In Paroxysmal Non-Kinesiogenic Dyskinesia they cannot be triggered, occur less frequently and last longer. Other paroxysmal dyskinesias include hypnogenic paroxysmal dyskinesias, paroxysmal exertional dyskinesia, infantile paroxysmal dystonias, Sandifer's syndrome and symptomatic paroxysmal dyskinesias. In Hereditary Episodic Ataxia Type 1 attacks of ataxia last for up to two minutes, may be accompanied

    In a randomised double blind prospective study, we tested the hypothesis that postoperative pain is lower in patients who receive an ProSeal LMA laryngeal mask airway compared with a tracheal tube. One hundred consecutive female patients (ASA I-II, 18-75 years) undergoing laparoscopic gynaecological surgery were divided into two equal-sized groups for airway management with the ProSeal LMA or tracheal tube. Anaesthesia management was identical for both groups and included induction of anaesthesia using propofol/fentanyl, and maintenance with propofol/remifentanil, muscle relaxation with rocuronium, positive pressure ventilation, gastric tube insertion, dexamethasone/tropisetron for anti-emetic prophylaxis, and diclofenac for pain prophylaxis. All types of postoperative pain were treated using intravenous patient-controlled analgesia (PCA) morphine. Patients and postoperative staff were unaware of the airway device used. Data were collected by a single blinded observer. We found that pain scores were lower for the ProSeal LMA at 2 h and 6 h but not at 24 h. Morphine requirements were lower for the ProSeal LMA by 30.4%, 30.6% and 23.3% at 2, 6 and 24 h, respectively. Nausea was less common with the ProSeal LMA than with the tracheal tube at 2 h and 6 h but not at 24 h. There were no differences in the frequency of vomiting, sore throat, dysphonia or dysphagia. We conclude that postoperative pain is lower for the ProSeal LMA than the tracheal tube in females undergoing gynaecological laparoscopic surgery.

    Surgical site infections (SSIs) are an important cause of morbidity following cesarean delivery, particularly in obese patients. Methods to reduce SSIs after cesarean delivery would have an important impact in obese obstetric patients. The purpose of this study was to determine whether the Alexis O cesarean delivery retractor, a barrier self-retaining retractor, reduces SSIs and wound disruptions in obese patients undergoing cesarean delivery. This was a randomized controlled trial of obese women (body mass index ≥ 30 kg/m(2)) undergoing nonemergent cesarean delivery. Patients were randomized to the treatment group (using the Alexis O cesarean delivery retractor) or to the control group (using conventional handheld retractors). The primary outcome was SSI or wound disruption during the 30 day postoperative period. Secondary outcomes included operative time, estimated blood loss, change in hemoglobin, antiemetic use, length of postoperative hospital stay, hospital readmission, and other postoperative complications. A total of 301 patients were enrolled in the study. One hundred forty-four patients were randomized to the treatment group and 157 to the control group. Baseline characteristics and indications for cesarean delivery were similar between the 2 groups. Median body mass index was 40.1 kg/m(2). There were no significant differences between the treatment and the control group in the primary outcome of SSI or wound disruption rates at the 30 day assessment (20.6% vs 17.6%, P = .62), during the postoperative inpatient hospitalization or at the 1-2 week postoperative visit. There were also no differences in the primary outcome when adjusting for obesity class or thickness of the subcuticular layer. Patients in the treatment group had lower rates of uterine exteriorization (54.3% vs 87.3%, P cesarean delivery deliveries did not decrease SSI or wound disruption rates in an obese population. Its use as a retractor should be left to the discretion of the surgeon

    The introduction of newly formulated extended release (ER) morphine with sequestered naltrexone (Embeda) has provided another treatment option for moderate to severe persistent pain. Embeda was designed to be an abuse-deterrent opioid formulation. Naltrexone is a centrally acting opioid receptor antagonist that blocks the action of opioid. When taken as directed, insignificant amount of sequestered naltrexone would reach systemic circulation, but upon tampering, the released naltrexone may blunt the euphoria of opioids, and possibly precipitate opioid withdrawal in opioid-dependent patient. To describe a case report ofa 50-year-old opioid-dependent male who developed acute opioid withdrawal after taking crushed Embeda. A 50-year-old male with severe, chronic low back pain due to degenerative disc disease was referred to our clinic for pain management. He was taking ER oxycodone 80 mg tid and Roxicodone 30 mg qid prn, with inadequate pain relief A trial of ER oxymorphone was decided, at 40 mg 1-2 doses bid. The patient returned to the clinic 1 week early, out of his ER oxymorphone. At this time, the decision to switch him to Embeda was made, at 80 mg/3.2 mg, 1-2 doses bid. The patient and his family members were counseled about risk involved with tampering with Embeda. A few hours later, our clinic was informed that the patient was brought to emergency room by ambulance, in severe opioid withdrawal. He was treated with IV fluid, antiemetics, clonidine, and IV hydromorphone. His condition improved and he was discharged home the next morning. Later on, the patient admitted that he took two prescribed Embeda within half an hour, the 1st one whole and the 2nd one crushed. He further admitted that he did so against our medical advice. CONCLUSION. Taking tampered Embeda may precipitate opioid withdrawal in opioid-tolerant patient. To the best of our knowledge, this is the first report of induced opioid withdrawal following consumption of crushed Embeda.

    Full Text Available Introduction: Cannabinoid hyperemesis syndrome (CHS is an entity associated with cannabinoid overuse. CHS typically presents with cyclical vomiting, diffuse abdominal pain, and relief with hot showers. Patients often present to the emergency department (ED repeatedly and undergo extensive evaluations including laboratory examination, advanced imaging, and in some cases unnecessary procedures. They are exposed to an array of pharmacologic interventions including opioids that not only lack evidence, but may also be harmful. This paper presents a novel treatment guideline that highlights the identification and diagnosis of CHS and summarizes treatment strategies aimed at resolution of symptoms, avoidance of unnecessary opioids, and ensuring patient safety. Methods: The San Diego Emergency Medicine Oversight Commission in collaboration with the County of San Diego Health and Human Services Agency and San Diego Kaiser Permanente Division of Medical Toxicology created an expert consensus panel to establish a guideline to unite the ED community in the treatment of CHS. Results: Per the consensus guideline, treatment should focus on symptom relief and education on the need for cannabis cessation. Capsaicin is a readily available topical preparation that is reasonable to use as first-line treatment. Antipsychotics including haloperidol and olanzapine have been reported to provide complete symptom relief in limited case studies. Conventional antiemetics including antihistamines, serotonin antagonists, dopamine antagonists and benzodiazepines may have limited effectiveness. Emergency physicians should avoid opioids if the diagnosis of CHS is certain and educate patients that cannabis cessation is the only intervention that will provide complete symptom relief. Conclusion: An expert consensus treatment guideline is provided to assist with diagnosis and appropriate treatment of CHS. Clinicians and public health officials should identity and treat CHS

    Intestinal leiomyositis is a suspected autoimmune disorder affecting the muscularis propria layer of the gastrointestinal tract and is a cause of chronic intestinal pseudo-obstruction in humans and animals. To characterize the clinical presentation, histopathologic features, and outcome of dogs with intestinal leiomyositis in an effort to optimize treatment and prognosis. Six client-owned dogs. Retrospective case series. Medical records were reviewed to describe signalment, clinicopathologic and imaging findings, histopathologic diagnoses, treatment, and outcome. All biopsy specimens were reviewed by a board-certified pathologist. Median age of dogs was 5.4 years (range, 15 months-9 years). Consistent clinical signs included vomiting (6/6), regurgitation (2/6), and small bowel diarrhea (3/6). Median duration of clinical signs before presentation was 13 days (range, 5-150 days). Diagnostic imaging showed marked gastric distension with dilated small intestines in 4/6 dogs. Full-thickness intestinal biopsies were obtained in all dogs by laparotomy. Histopathology of the stomach and intestines disclosed mononuclear inflammation, myofiber degeneration and necrosis, and fibrosis centered within the region of myofiber loss in the intestinal muscularis propria. All dogs received various combinations of immunomodulatory and prokinetic treatment, antimicrobial agents, antiemetics, and IV fluids, but none of the dogs showed a clinically relevant improvement with treatment. Median survival was 19 days after diagnosis (range, 3-270 days). Intestinal leiomyositis is a cause of intestinal pseudo-obstruction and must be diagnosed by full-thickness intestinal biopsy. This disease should be considered in dogs with acute and chronic vomiting, regurgitation, and small bowel diarrhea. Copyright © 2015 The Authors.

    With the advances in cancer treatments, mortality rates in the United States have been consistently falling but they are accompanied by substantial increases in the cost of cancer care. Patient and prescription assistance programs (PPAPs) are offered by pharmaceutical manufacturers to provide free medications to medically indigent patients. To assist the Cancer Care Center (CCC) at Nassau University Medical Center (NUMC) with drug costs for chemotherapies, the pharmacy department uses a patient assistance program (PAP) to obtain medications from the drug companies at no cost. This study evaluates the impact of the PAP at a public hospital from which indigent cancer patients obtain assistance for chemotherapy. We followed all patients requiring assistance with chemotherapy who enrolled in the PAP from January 1, 2011 through December 31, 2012. Medications included both oral and parenteral chemotherapy drugs and antiemetics used in the outpatient clinic setting. The program served 347 patients in 2011 and 579 patients in 2012. The total number of visits in the clinic over 24 months was 9,405. The total cost savings of the medications was $1,066,000 in 2011 and $1,715,538 in 2012. A pharmacy-based PAP to procure free medications from PPAPs for cancer patients has helped to defray the expense of providing care at NUMC, increased patients' compliance with chemo protocols, and allowed many patients to receive the treatment they otherwise would not be able to afford. The combination of PPAPs and PAP provides a safety net to ensure that indigent cancer patients receive needed prescription medications in the outpatient clinic setting.

    The rapid technological advancement has increased human exposure to ionizing radiations enormously. Ionizing radiations produces deleterious effects in the living organisms. Widespread use of radiation in diagnosis therapy, industry, energy sector and inadvertent exposure during air and space travel, nuclear accidents and nuclear terror attacks requires safeguard against human exposures. Lead shielding and other physical measures can be used in such situations but with difficulty to manage; thus pharmacological intervention could be the most prudent strategy to protect humans against the harmful effect of ionizing radiations. These pharmacological agents are radioprotectives; The development of radioprotective agents has been the subject of intense research in view of their potential for use within a radiation environment. However, no ideal, safe synthetic radio protectors are available to date, so the search for alternative sources including plants has been ongoing. In Ayurveda, the traditional Indian system of medicine, several plants have been used to treat free radical-mediated ailments and, therefore, it is logical to expect that such plants may also render some protection against radiation damage. This all is due to antioxidant enzymes, nitroxides, and melatonin, antiemetic, anti-inflammatory. haemopoitic and immunostimulant compounds. Some of the plants which are found to be radioprotective are Centella asiatica, Ginkgo biloba, Hippophae rhamnoides, Ocimum sanctum, Podophyllurn hexandrum, Tinospora cordifolia, Emblica officinalis, Phyllanthus amarus, etc. So there is an urgent need to identify and characterize the many of the plants in relation to the radioprotection. Besides these medicinal plants there are also some fruits and vegetables which are having good response against harmful radiations such as Kiwifruit Actinidia deliciosa (Actinidaceae), Cape Gooseberry Physalis peruviana (Solanaceae). They protect against the radiation-induced damage by

    Colorectal cancer is one of the main causes of mortality in both developed and developing countries, including Iran. One of the treatments available for colorectal cancer is chemotherapy, of which nausea and emesis are the side effects. Owing to problems in controlling the side effects, a combination of medicine and non-medicine interventions is usually used. Self-care is one of the non-medicine interventions in this regard. The present study was aimed at surveying the effect of a self-care education program on severity of nausea and emesis in colorectal cancer patients under chemotherapy. A semi-experimental study was carried out in Imam Reza Hospital of Kermanshah, Iran. The sample group comprised 52 patients with colorectal cancer under chemotherapy. Data gathering tools included a demographics questionnaire and Morrow Assessment of Nausea and Emesis. To control intensity of nausea and emesis, a package of self-care measures including muscular progressive relaxation, music, and education on nutrition was used. Afterward, the collected data were analyzed using statistical tests such as Shapiro-Wilk test (to check normal distribution of the data), Mann-Whitney U test, Wilcoxon test, and chi-square test with the help of SPSS 20. The results showed a considerable decrease in intensity and frequency of nausea and emesis after the intervention. The p -value of Mann-Whitney U test results with regard to intensity of nausea in the experiment and control groups after the intervention was 0.029; this figure for intensity of emesis was 0.009, which indicated effectiveness of the self-care program. As the results showed, using self-care program could be effective in attenuating intensity of emesis and nausea in colorectal cancer patients under chemotherapy. So, it can be concluded that the use of this program can increase the patient's self-care ability to control vomiting and nausea, which can be considered as a complementary approach to the antiemetic medications.

    Adverse drug reactions (ADRs) to N-acetylcysteine (NAC) treatment for paracetamol overdose are typically anaphylactoid in origin and occur in 2-48% of treated patients. We explored the incidence and management of NAC ADR in our unit. Case notes of patients who presented with paracetamol overdose and had ADR to NAC between February 2005 and June 2011 were reviewed. A total of 1648 patients presented with suspected paracetamol overdose and 660 received NAC treatment. Within this group, 82 patients had documented NAC-related ADR. ADR developed in 12.4% (82/660) of patients receiving intravenous NAC and 59 had full documentation available and were included in this study (34 women, 25 men). ADR occurred in the 15-min (150 mg/kg) bag in 36 cases (61%), 22 in the 4-h (50 mg/kg) bag (37%) and one in the 16-h (100 mg/kg) bag (2%). Symptoms were classified as minimal (n=16, 27%), moderate (n=26, 44%) and severe (n=17, 29%). Asthma and female sex, which are reported risk factors for ADR, did not lead to the development of more severe ADR (P=0.771 and 0.330, respectively). Treatments administered included stopping the NAC infusion (n=32, 54%), administration of antiemetics (n=36, 61%), H1 antihistamines (n=26, 44%), steroids (n=16, 27%), inhaled B2 agonists (n=6, 10%) and adrenaline (n=3, 5%). The incidence of ADR to NAC was comparable with published studies, although there was no association of severity with asthma or female sex. The management of ADRs is variable, with frequent, inappropriate use of steroids. Education about the pathophysiology of these ADRs may improve management.

    Midodrine prevents post-space flight orthostatic intolerance when testing is conducted in a controlled laboratory setting within 2-4 hours after Space Shuttle landing. It is unknown if midodrine is as effective during re-entry and immediately following landing. METHODS: Cardiovascular responses to 10 minutes of 80 head-up tilt in five male astronauts were compared before and immediately after Space Shuttle missions. Preflight tests were conducted in the Johnson Space Center Cardiovascular Laboratory without midodrine. Post-flight testing was performed in the Crew Transport Vehicle on the Space Shuttle runway within 60 minutes of landing; midodrine was self-administered before re-entry. Survival analysis was performed (Gehan-Breslow test) to compare presyncope rates pre- to post-flight. Cardiovascular responses (last minute standing minus supine) to tilt before and after space flight were compared using paired t-tests. RESULTS: Midodrine did not prevent post-flight orthostatic hypotension in two of the five astronauts, but the rate of presyncope across the group did not increase (p=0.17) from pre- to post-flight. Also, although the change in heart rate from supine to the last minute of standing was not affected by space flight, systolic blood pressure decreased more (p=0.05) and diastolic blood pressure tended to decrease (p=0.08) after space flight. CONCLUSIONS: Accurate interpretation of the current results requires that similar data be collected in control subjects (without midodrine) on the CTV. However, drug interaction concerns with commonly used anti-emetics and potentiation of prolonged QTc intervals observed in long duration astronauts make the routine use of midodrine for immediate post-flight orthostatic hypotension unlikely. 2

    Full Text Available Abstract Background Diarrhoea accounts for 20% of all paediatric deaths in India. Despite WHO recommendations and IAP (Indian Academy of Paediatrics and Government of India treatment guidelines, few children suffering from acute diarrhoea in India receive low osmolarity oral rehydration solution (ORS and zinc from health care providers. The aim of this study was to analyse practitioners' prescriptions for acute diarrhoea for adherence to treatment guidelines and further to determine the factors affecting prescribing for diarrhoea in Ujjain, India. Methods This cross-sectional study was conducted in pharmacies and major hospitals of Ujjain, India. We included prescriptions from all practitioners, including those from modern medicine, Ayurveda, Homeopathy as well as informal health-care providers (IHPs. The data collection instrument was designed to include all the possible medications that are given for an episode of acute diarrhoea to children up to 12 years of age. Pharmacy assistants and resident medical officers transferred the information regarding the current diarrhoeal episode and the treatment given from the prescriptions and inpatient case sheets, respectively, to the data collection instrument. Results Information was collected from 843 diarrhoea prescriptions. We found only 6 prescriptions having the recommended treatment that is ORS along with Zinc, with no additional probiotics, antibiotics, racecadotril or antiemetics (except Domperidone for vomiting. ORS alone was prescribed in 58% of the prescriptions; while ORS with zinc was prescribed in 22% of prescriptions, however these also contained other drugs not included in the guidelines. Antibiotics were prescribed in 71% of prescriptions. Broad-spectrum antibiotics were prescribed and often in illogical fixed-dose combinations. One such illogical combination, ofloxacin with ornidazole, was the most frequent oral antibiotic prescribed (22% of antibiotics prescribed. Practitioners from

    Full Text Available Albert TucaPalliative Care Hospital Team, Palliative Care Department, Institut Català d’Oncologia, L’Hospitalet de Llobregat, Barcelona, SpainAbstract: Until now only intravenous and oral formulations of 5HT3 receptor antagonists have been available. Recently a new formulation of a 5HT3 receptor antagonist, transdermal granisetron, has been developed, and approved by the FDA. Three phase I studies to evaluate its pharmacokinetic profile have shown that granisetron administered by a transdermal delivery system is absorbed by passive diffusion and maximal concentration is reached 48 hours after patch application. The patch of 52 cm2, which contains 34.3 mg of granisetron, releases 3.3 mg of the drug every day and maintains a stable average plasma concentration of 2.2 ng/mL over 6 days, similar to levels obtained with 2 mg of oral granisetron, administered every day during the same period of time. Two randomized as yet unpublished clinical trials (phase II/III have been conducted to evaluate the antiemetic efficacy of transdermal granisetron in chemotherapy-induced nausea and vomiting, in patients receiving moderately and highly emetogenic chemotherapy, compared with 2 mg of oral granisetron. More than 800 cancer patients were included in the trials. The rate of complete control of acute emesis was 49% for the phase II trial and 60% for the phase III trial. Neither trial showed a statistically significant difference between transdermal and oral granisetron. The control of delayed emesis was observed in 46% of patients, and there were no statistically significant differences between transdermal and oral granisetron. The most common adverse effects in both trials were constipation (<7% and headache (<1%; there were no statistically significant differences between transdermal and oral granisetron. These data show that transdermal granisetron is effective and safe in controlling acute emesis induced by chemotherapy with both moderate and high

Objective: Therefore, this meta-analysis was conducted to evaluate the efficacy of olanzapine containing regimen in preventing acute, delayed and overall phases of CINV. Methods: PubMed, EBSCO, and Cochrane central register of controlled trials electronic databases were searched to identify RCTs that compared the effects of olanzapine with non-olanzapine regimen in preventing CINV. Randomized clinical trials (RCTs that compared olanzapine containing regimen with non-olanzapine regimen were included. The primary outcomes were the percentage of patients achieving no vomiting or no nausea in acute, delayed and overall phases. Results: 13 RCTs that enrolled 1686 participants were included in this meta-analysis. 852 patients were assigned to olanzapine and 834 patients were assigned to non-olanzapine regimen (other standard antiemetic regimen. The percentages of no emesis achieved were 87.5%, 76.2%, 73.6% in olanzapine versus 76.7%, 61.8%, and 56.4% in non-olanzapine regimen in acute, delayed and overall phases, respectively. The percentages of no nausea were 82%, 64.3%, 61.6% in olanzapine group versus 71.3%, 41.8%, and 40.6% in non-olanzapine group in acute, delayed and overall phases, respectively. In general, olanzapine containing regimen achieved statistical superiority to non-olanzapine regimen in no vomiting endpoint in acute phase (OR 2.16; 95%CI 1.60 to 2.91, p<0.00001; I-square=5%; p=0.40, delayed phase (OR 2.28; 95%CI 1.1.46 to 3.54, p=0.0003; I-square=65%; p=0.001 and overall phase (OR 2.48; 95%CI 1.59 to 3.86, p<0.0001; I-square=69%; p< 0.0001.

    Full Text Available Background: The objective was to evaluate the cost-effectiveness of NEPA, an oral fixed combination netupitant (NETU, 300 mg and palonosetron (PA, 0.5 mg compared with aprepitant and palonosetron (APPA or palonosetron (PA alone, to prevent chemotherapy-induced nausea and vomiting (CINV in patients undergoing treatment with highly or moderately emetogenic chemotherapy (HEC or MEC in the UK. Scope: A systematic literature review and meta-analysis were undertaken to compare NEPA with currently recommended anti-emetics. Relative effectiveness was estimated over the acute (day 1 and overall treatment (days 1–5 phases, taking complete response (CR, no emesis and no rescue medication and complete protection (CP, CR and no more than mild nausea [VAS scale <25 mm] as primary efficacy outcomes. A three-health-state Markov cohort model, including CP, CR and incomplete response (no CR for HEC and MEC, was constructed. A five-day time horizon and UK NHS perspective were adopted. Transition probabilities were obtained by combining the response rates of CR and CP from NEPA trials and odds ratios from the meta-analysis. Utilities of 0.90, 0.70 and 0.24 were defined for CP, CR and incomplete response, respectively. Costs included medications and management of CINV-related events and were obtained from the British National Formulary and NHS Reference Costs. The expected budgetary impact of NEPA was also evaluated. Findings: In HEC patients, the NEPA strategy was more effective than APPA (quality-adjusted life days [QALDs] of 4.263 versus 4.053; incremental emesis-free and CINV-free days of +0.354 and +0.237, respectively and was less costly (£80 versus £124, resulting in NEPA being the dominant strategy. In MEC patients, NEPA was cost effective, cumulating in an estimated 0.182 extra QALDs at an incremental cost of £6.65 compared with PA. Conclusion: Despite study limitations (study setting, time horizon, utility measure, the results suggest NEPA is cost

Furthermore, 25.96% ADRs were due to anticonvulsants, followed by antibiotics (22.11%, antipyretics (11.53%, vaccination (8.65%, steroids (6.73%, decongestants (5.67%, snake antivenom and antiemetics (3.84%, and fluids, insulin, and antacids (1.92%. The patients’ dermatological system was involved in 67.30%, followed by the central nervous system (CNS in 11.53% patients. Renal system was involved in 6.73% patients. Cardiac, musculoskeletal, metabolic, and other systems were involved in 4.80%, 3.84%, 2.88%, and 0.96%, respectively. According to the Hartwig severity scale of ADRs, 64.4% patients had moderate ADRs, 29.8% patients had severe ADRs, and 5.76% had mild ADRs. In the present study, 64.4% patients expressed moderate severity, whereas 29.8% expressed high severity and 5.76% expressed mild ADRs. Conclusion ADRs were seen in 71% of the patients between 1 and 5 years of age, 26% in the age group of 5–10 years, and 3% were more than 10 years old. Anticonvulsants (25.96% and antibiotics (22.11% were

    CASE STUDYBJ is a 34-year-old woman who was diagnosed with metastatic breast cancer. She was treated with surgical removal of the primary tumor and sentinel node biopsy. Following surgery, she received chemotherapy. She was given antiemetic therapy prior to and immediately following chemotherapy. She began to experience significant and persistent nausea with intermittent episodes of vomiting after the second cycle of chemotherapy. She completed her chemotherapy but still experienced nausea and vomiting in response to several cues, such as smelling food cooking and going to the hospital. Her nausea and vomiting resulted in segregation from her family during meal time, which negatively impacted her quality of life. A hypnosis consultation was requested, and BJ was cooperative. She reported feeling very nauseated at the time of the interview. Hypnosis was discussed; her questions were answered, and the potential risks and benefits of hypnosis were reviewed. She agreed that she would like to try hypnosis. A hypnosis assessment was conducted and revealed that she had a history of profound motion sickness and severe, chronic childhood trauma associated with feelings of anxiety and hypervigilance. The therapeutic suggestions that were used with BJ included hypnotic suggestions for relaxation and removal of discomfort. A metaphor describing the central processing of the anticipatory nausea and vomiting as a thermostat that could be adjusted to reduce and eliminate the sensation was used to suggest that she could control her perceptions and in turn control the nausea. Posthypnotic suggestions included that at the earliest awareness of discomfort, rubbing the throat would eliminate that discomfort, and cooking aromas would be transformed into her favorite fragrance. Reversal went smoothly, and BJ reported satisfaction with the experience. BJ experienced significant reduction in symptoms after the first session. She had two more sessions, at which time she was able to eat

    Self-medication is a universal challenge that requires attention because of the potential threat not only to the pregnant women but also to unborn child. Data on self-medication practice and predictors among pregnant women is lacking in Tanzania. Information on the effects of this practice to the pregnant woman and the foetus globally is also scanty. This was a cross sectional study which was conducted using face to face interview with 372 pregnant women at Makongoro health centre. Semi-structured questionnaires were used. Data were analysed using STATA 13 (Statistical Corporation, College Station, Texas, US). A total of 372 pregnant women participated in the study. The prevalence of self-medication among pregnant women was 172 (46.24%). There was a significant statistical association between self-medication and occupation (P value =0.01), gestation age (P self-medication (P = 0.809, P = 0.243 and P = 0.922) respectively. When bivariate logistic regression was performed, occupation and education were the only determining factors for self-medication. Pregnant women who were unemployed, doing business and house wife were most likely to practice self-medication than employed pregnant women (P = 0.03; OR = 2.33; 95% CI, 1.06-5.31, P = 0.01; OR = 2.31; CI 1.21-4.41, P = self-medication than pregnant women with college or university education (P leading illness/symptoms which led to self-medication among pregnant women attending clinic were malaria 56 (32.56%, morning sickness 44 (25.55%) and headache 33(19.19%). Drugs commonly used in self-medication among pregnant women were ant malarial 42 (24.42%), antiemetics 59 (34.30%) and analgesics 33 (19.19%). Prevalence of self-medication among pregnant women is high in Tanzania. This is a threat to the safety of the developing foetus and the pregnant woman. Therefore there is a need of interventions to minimize the practice among pregnant women.

    Vomiting in children with acute gastroenteritis (AG) is not only a direct cause of fluid loss but it is also a major factor of failure of oral rehydration therapy (ORT). Physicians who provide care to paediatric patients in the emergency department (ED) usually prescribe intravenous fluid therapy (IVT) for mild or
