    2017-02-01

    Question Parents of a 12-month-old boy are bringing their son in to my family practice clinic for his well-baby visit. As the infant is due for his 12-month vaccine series, the parents are concerned after hearing about the association between certain vaccinations and an increased risk of febrile seizures, and are wondering if they should administer prophylactic antipyretics to decrease the risk of febrile seizure. What vaccinations are associated with increased risk of febrile seizure, and is there evidence supporting prophylactic administration of antipyretics to prevent febrile seizures? Answer Vaccinations associated with increased risk of febrile seizure include the following: the measles-mumps-rubella vaccine; the measles-mumps-rubella-varicella vaccine; the combined diphtheria, tetanus, acellular pertussis, polio, and Haemophilus influenzae type b vaccine; the whole-cell pertussis vaccine; the 7-valent pneumococcal conjugate vaccine; and concomitant administration of the trivalent inactivated influenza vaccine with either the 7-valent pneumococcal conjugate vaccine or the diphtheria, tetanus, and acellular pertussis vaccine. Despite being a higher-risk group, children receiving these vaccinations should not receive prophylactic antipyretics, as no statistically significant reduction in the rate of febrile seizures has been documented, and prophylactic antipyretic use potentially decreases the immune response to certain vaccines.

    2015-01-01

    Background and Objective The effect of antipyretic therapy on mortality in patients with sepsis remains undetermined. The present study aimed to investigate the role of antipyretic therapy in ICU patients with sepsis by using a large clinical database. Methods The multiparameter intelligent monitoring in intensive care II (MIMIC- II) database was employed for the study. Adult patients with sepsis were included for analysis. Antipyretic therapy included antipyretic medication and external cooling. Multivariable model with interaction terms were employed to explore the association of antipyretic therapy and mortality risk. Main Results A total of 15,268 patients fulfilled inclusion criteria and were included in the study. In multivariable model by treating temperature as a continuous variable, there was significant interaction between antipyretic therapy and the maximum temperature (Tmax). While antipyretic therapy had no significant effect on mortality in low temperature quintiles, antipyretic therapy was associated with increased risk of death in the quintile with body temperature >39°C (OR: 1.29, 95% CI: 1.04–1.61). Conclusion Our study shows that there is no beneficial effect on reducing mortality risk with the use of antipyretic therapy in ICU patients with sepsis. External cooling may even be harmful in patients with sepsis. PMID:25822614

    Full Text Available The study was conducted to screen the antipyretic activity of alcoholic extract of the stem bark of Bauhinia racemosa Lam. as per the method discribed by Bhalla et.al, (1971. Thirty six healthy rats weighing between 200-250gms were divided into six groups of six animals each, with 50% sex ratio. The initial rectal temperature of each animal was recorded by digital thermometer and its hourly variation was noted for 3 hours. The pyrexia was induced by injecting a suspension of 15% of brewer’s yeast and 2% gum acacia in normal saline sub-cutaneously below the nape of neck @ 1ml/100gm of animal weight. The difference in temperature between 0 hour and respective time interval was found out by statistical method. The potency of extract to bring down the temperature was compared with that of the control group. The extract showed marked antipyretic activity in a dose dependent manner.

    Fever or Pyrexia means abnormal rise in body temperature above the usual range of normal in response to a variety of infectious, immunological and neoplastic stimuli. To normalize these febrile conditions, several synthetic agents are in clinical practice such as acetaminophen, ibuprofen, and aspirin. However, they are having many side effects which sometimes challenge their applications. The various sources are under investigation worldwide to overcome issues of unwanted effects and to better therapeutic response. In this scenario botanicals such as alkaloids, the most widely distributed and studied plant secondary metabolites, could effectively produce the molecules with better antipyretic effect and safety profile. The current review deals with 21 isolated alkaloids from 14 plants species having some antipyretic effect in preliminary screening/preclinical studies with the possible mechanism and structural edges. Therefore, these alkaloids of plant origin are candidates for further detail studies to ascertain their mechanism(s) and clinical utility or as lead compounds for future drugs.

    1991-06-01

    Lyophilised aqueous extract of Euphorbia hirta L. (Euphorbiaceae) has been evaluated for analgesic, antipyretic and anti-inflammatory properties in mice and rats, in order to complete its activity profile, after the confirmation of the existence of a central depressant activity particularly expressed by a strong sedative effect, associated with anxiolytic effects. This study leads us to the conclusion that this plant extract exerts central analgesic properties. Such a dose-dependent action was obtained against chemical (writhing test) and thermic (hot plate test) stimuli, respectively, from the doses of 20 and 25 mg/kg and it was inhibited by a naloxone pretreatment, a specific morphinic antagonist compound. An antipyretic activity was obtained at the sedative doses of 100 and 400 mg/kg, on the yeast-induced hyperthermia. Finally, significant and dose-dependent anti-inflammatory effects were observed on an acute inflammatory process (carrageenan-induced edema test in rats) from the dose of 100 mg/kg. On the other hand, plant extract remained inactive on chronic processes such as Freund's adjuvant-induced rheumatoid arthritis, after a chronic treatment during fourteen days at the daily dose of 200 or 400 mg/kg; however, if inefficacy was observed on rat backpaws edema and on loss of weight, the aqueous extract reduced the inflammatory hyperalgia.

    Analgesic, antipyretic activity and toxicity study of the leaves of Bryonia laciniosa Linn. (Family: Cucurbitaceae) was evaluated in the standard animal models. The methanol extract of Bryonia laciniosa (MEBL) was evaluated by hot plate and acetic acid-induced writhing methods to assess analgesic activity. The antipyretic activity of the extract was also evaluated by normal body temperature and yeast-induced hyperpyrexia. The extract showed significant analgesic and antipyretic activity. The MEBL was further evaluated for toxicity at the doses of 125 and 250 mg/kg administered orally for 14 days in rats. At the end of experiments, the blood, liver function and kidney metabolism were observed. The hematological profile and different biochemical parameters such as SGOT, SGPT and ALP were estimated. The present study revealed that MEBL exhibited significant analgesic and antipyretic activity in the tested experimental animal models. The toxicity study indicates that the extract is not toxic at the tested doses.

    2004-11-01

    The present study was designed to investigate the anti-pyretic and analgesic activity of ethanol (EEO) and aqueous (AEO) extracts of Emblica officinalis fruits in several experimental models. A single oral dose of EEO and AEO (500 mg/kg, i.p.) showed significant reduction in brewer's yeast induced hyperthermia in rats. EEO and AEO also elicited pronounced inhibitory effect on acetic acid-induced writhing response in mice in the analgesic test. Both, EEO and AEO did not show any significant analgesic activity in the tail-immersion test. These findings suggest that extracts of Emblica officinalis fruits possessed potent anti-pyretic and analgesic activity. Preliminary phytochemical screening of the extracts showed the presence of alkaloids, tannins, phenolic compounds, carbohydrates and amino acids, which may be responsible for anti-pyretic and analgesic activities.

    2010-02-01

    This study investigated some pharmacological properties of virgin coconut oil (VCO), the natural pure oil from coconut [Cocos nucifera Linn (Palmae)] milk, which was prepared without using chemical or high-heat treatment. The anti-inflammatory, analgesic, and antipyretic effects of VCO were assessed. In acute inflammatory models, VCO showed moderate anti-inflammatory effects on ethyl phenylpropiolate-induced ear edema in rats, and carrageenin- and arachidonic acid-induced paw edema. VCO exhibited an inhibitory effect on chronic inflammation by reducing the transudative weight, granuloma formation, and serum alkaline phosphatase activity. VCO also showed a moderate analgesic effect on the acetic acid-induced writhing response as well as an antipyretic effect in yeast-induced hyperthermia. The results obtained suggest anti-inflammatory, analgesic, and antipyretic properties of VCO.

    Fever is one of the most common complaints in Pediatrics. We performed this study to know how pediatricians use antipyretics to manage fever in children, and Internet was used to collect data. On line survey with a questionnaire regarding general and specific issues about fever. 1600 pediatricians participated. 62% were female, 35% had less than 10 years of practice, 28% between 10 and 20 years of practice, and 33% over 20 years of practice. 67% had training in Pediatrics. 93% use the arm-pit to measure fever and 37% consider over 38 degrees C as being fever. The mostly used antithermic in older than 6 month was Ibuprofeno and in younger than 6 months, Paracetamol. 59% of the pediatricians alternate 2 antipyretics (63.7% with less than 20 year of experience versus 49.3% with > 20 years of experience in their profession); 29% define their actions based on the Argentine Society of Pediatrics guidelines and 26% on their personal experience. Pediatricians prescribe antipyretics regularly alternating them in spite of the lack of evidence supporting that behavior. The less experienced the pediatrician, the more frecuent the practice of alternating antipyretics.

    Pyrexia and inflammation are indicatives of various disorders. Modern medicines are available for treatment of pyrexia, but they have few side effects. Several studies are ongoing Worldwide to search natural antipyretic agents with better efficacy and fewer or no side effects. This study was aimed at evaluating the antipyretic activity of Moringa oleifera bark in rabbits against E. coli induced pyrexia. Rectal temperature was recorded with digital thermometer at 0 h and E. coli suspension was injected. After 1 h again rectal temperature of the animals was recorded and hydro-alcoholic extract were administered to the treatment groups and paracetamol hydro-alcoholic 50 mg/kg orally to the positive control group. Then rectal temperature was recorded at the interval of one h for 4 h. After the drug administration (at h 1), the decrease in body temperature with the dose of 25mg/kg(-1) during next four h ranged between 1.9-2.6of as compared to the negative control. At the dose of 50mg/kg(-1) the decrease in temperature was 1.9-3.0 of. The decrease in body temperature at the dose of 100mg/kg(-1) was high, which ranged from 2.3-3.1of as compared to negative control. Paracetamol, a standard drug , also significantly lowered the temperature but Moringa oleifera at the concentration of 100mg/kg(-1) lowered the body temperature significantly as compared to the negative as well as positive control. Moringa oleifera bark has marked antipyretic activity in animal models and this strongly supports the ethnopharmacological uses of Moringa oleifera bark as an antipyretic plant.

    In this study we describe a low-cost and reliable method for inducing fever in young male rats (28-30 days of age, 75-90 g), which seems suitable for the screening of new antipyretics. The effects of temperature measuring procedure-induced stress on the basal rectal temperature and on Baker yeast-induced hyperthermia was assessed. Rectal temperature (T) was recorded every hour for 12 h (07:00-19:00 h) with a lubricated thermistor probe. The animals were injected intraperitoneally with baker yeast (0.25, 0.135, 0.05 g/kg) or the equivalent volume of saline at 7:00 h. The administration of 0.135 g/kg baker yeast induced a sustained increase in rectal temperature for 4 h. Classical (dipyrone and acetaminophen) and novel (MPCA and FPCA) antipyretics, at doses that had no effect per se, reverted baker yeast-induced fever. The method presented induces a clear-cut fever, which is reverted by antipyretics commonly used in human beings and selected novel antipyretics in small animals. The method also allows antipyretic evaluation with low amount of drugs, due to the use of small animals and to the small variability of the pyretic response, which ultimately causes a significant reduction in the number of animals necessary for antipyretic evaluation. Therefore, this study describes an animal model of fever that is not only advantageous from the economical and technical point of view, but that also bears ethical concerns.

    Mahuang-Shigao herb-pair is a famous formula composed of Ephedra and Gypsum. The herb-pair is frequently used for treating cold symptoms and bronchial asthma in the clinical practice of Chinese medicine (CM). In the present study, we evaluated evidence for the benefit of combined use of Ephedra and Gypsum by analyzing the antipyretic and anti-asthmatic activities of Ephedra-Gypsum. The antipyretic effects of Ephedra-Gypsum were evaluated in yeast-induced hyperthermia test. Thirty male Wistar rats were randomly divided into 5 groups, including control group, standard aspirin group, and 3 Ephedra- Gypsum groups of different doses (6, 12, 24 g/kg). Ephedra-Gypsum extract and asprin were administered orally 6 h after the injection of yeast solution and body temperature was measured every 1 h for 8 h. The antiasthmatic effects of Ephedra-Gypsum were evaluated using an ovalbumin (OVA)-induced asthmatic rat model. Thirty-six male SD rats were randomly divided into 6 groups. Rats were alternately sensitized and OVA+Al(OH) challenged by exposure to mists of ovalbumin. Ephedra-Gypsum extracts (6, 12, 24 g/kg) or dexamethasone were administered 45 min prior to the allergen challenge for 8 days. Latent period and the weight of wet to dry ratio of lung were determined. In addition, the eosinophils in blood and white blood cell (WBC) were counted by an YZ-Hemavet Analyzer. The Ephedra-Gypsum extracts at test dose (6, 12, 24 g/kg) significantly and dose-dependently attenuated yeast-induced fever in rats. The Ephedra-Gypsum extracts also prolonged the latent period, reduced OVA-induced increases in eosinophils and WBC, and decreased the wet and dry weight ratio of the lungs in the anti-asthmatic test. These findings indicate that the Ephedra-Gypsum extract has antipyretic and anti-asthmatic properties. Hence, the results support additional scientific evidence in prescriptions.

    Full Text Available In Thailand, the leaves of Aquilaria crassna have been used traditionally for the treatments of various disorders, but without any scientific analysis. In this study, the antipyretic, analgesic, anti-inflammatory and anti-oxidative properties of A. crassna leaves extract were investigated at a wide dose range in rodents. Experimental animals were treated orally with an aqueous extract of Aquilaria crassna leaves (ACE. They were tested for antipyretic (Baker′s yeast-induced fever in rats, analgesic (hot plate test in mice and anti-inflammatory (carrageenan-induced paw edema in rats activities. An anti-oxidative effect of ACE was evaluated by using the DPPH anti-oxidant assay. The results showed that, after 5 hours of yeast injection, 400 and 800 mg/kg ACE significantly reduced the rectal temperature of rats. Mice were found significantly less sensitive to heat at an oral dose of 800 mg/kg ACE, after 60 and 90 min. No anti-inflammatory activity of ACE at an 800 mg/kg dose could be observed in the rat paw assay. An anti-oxidative activity of ACE was observed with an IC 50 value of 47.18 μg/ ml. No behavioral or movement change could be observed in mice after oral administration of ACE (800 or 8,000 mg/kg for seven consecutive days. Interestingly, from the second day of treatment, animals had a significant lower body weight at the 8,000 mg/kg dose of ACE compared to the control. No toxicity was identified and the results of this study state clearly that Aquilaria crassna leaves extracts possess antipyretic, analgesic and anti-oxidative properties without anti-inflammatory activity.

    Prophylactic antipyretic administration decreases the post-vaccination adverse reactions. Recent study finds that they may also decrease the antibody responses to several vaccine antigens. This systematic review aimed to assess the evidence for a relationship between prophylactic antipyretic administration, post-vaccination adverse events, and antibody response in children. A systematic search of major databases including MEDLINE and EMBASE was carried out till March 2014. Randomized controlled trials (RCTs) comparing prophylactic antipyretic treatment versus placebo post-vaccination in children ≤ 6 years of age were included. Two reviewers independently applied eligibility criteria, assessed the studies for methodological quality, and extracted data [PROSPERO registration: CRD42014009717]. Of 2579 citations retrieved, a total of 13 RCTs including 5077 children were included in the review. Prophylactic antipyretic administration significantly reduced the febrile reactions (≥ 38.0 °C) after primary and booster vaccinations. Though there were statistically significant differences in the antibody responses between the two groups, the prophylactic PCM group had what would be considered protective levels of antibodies to all of the antigens given after the primary and booster vaccinations. No significant difference in the nasopharyngeal carriage rates (short-term and long-term) of H. influenzae or S. pneumoniae serotypes was found between the prophylactic and no prophylactic PCM group. There was a significant reduction in the local and systemic symptoms after primary, but not booster vaccinations. Though prophylactic antipyretic administration leads to relief of the local and systemic symptoms after primary vaccinations, there is a reduction in antibody responses to some vaccine antigens without any effect on the nasopharyngeal carriage rates of S. pneumoniae & H. influenza serotypes. Future trials and surveillance programs should also aim at assessing the

    The objective was to study the antipyretic and hemodynamic effects of three different drugs used to treat fever in critically ill patients. Prospective, observational study in a 16-bed, general ICU of a university hospital. We studied 150 patients who had a febrile episode (temperature>38°C): 50 received paracetamol, 50 metamizol and 50 dexketoprofen. None. Body temperature, systolic, diastolic and mean arterial pressure, heart rate, central venous pressure and oxygen saturation were determined at baseline and at 30, 60 and 120minutes after infusion of the drug. Additionally, we recorded temperature 180minutes after starting drug infusion. Diuresis and the need for or change of dose of vasodilator or vasoconstrictor drugs were also recorded. Patient characteristics, baseline temperature and hemodynamics were similar in all groups. We observed a significant decrease of at least 1°C in temperature after 180minutes in 38 patients treated with dexketoprofen (76%), in 36 with metamizol (72%), and in 20 with paracetamol (40%) (pdexketoprofen (p=0.005). Dexketoprofen was the most effective antipyretic agent at the doses tested. Although all three drugs reduced mean arterial pressure, the reduction with paracetamol was less pronounced.

    Full Text Available The effects of the extracts from Hibiscus sabdariffa calyces L. (H. sabdariffa on nociceptive response using writhing, hot plate and formalin test in mice and the antipyretic activity in yeast-induced fever in rats, were examined. Anti-inflammatory activity was also investigated on carrageenin-induced paw edema in rats. No acute toxicity was observed in mice after oral administration of the ethanol and aqueous extract of H. sabdariffa calyces at the dose of 15 g/kg. Oral administration of the ethanol extract at the dose of 800 mg/kg significantly decreased the number of contortions and stretchings induced by acetic acid in mice. The aqueous extracts had no effect on this test. Neither the ethanol nor aqueous extract had an effect in the formalin and hot plate tests in mice. The ethanol and the vacuum dried extract of H. sabdariffa calyces (200-800 mg/kg, p.o. decreased the yeast-induced fever in rats. The H. sabdariffa extract had no effect on carrageenininduced paw edema in rats. These results suggest that the ethanol and aqueous extract (vacuum dry of H. sabdariffa calyces possess antipyretic action through mechanisms that are different from that of aspirin.

    Full Text Available The study aims to evaluate analgesic and antipyretic activities of the methanol extract and its different fractions from root of Schoenoplectus grossus using acetic acid induced writhing and radiant heat tail flick method of pain models in mice and yeast induced pyrexia in rats at the doses of 400 and 200 mg/kg. In acetic acid writhing test, the methanol extract, petroleum ether, and carbon tetrachloride fractions produced significant (P<0.001 and P<0.05 inhibition of writhing responses in dose dependent manner. The methanol extract at 400 and 200 mg/kg being more protective with 54% and 45.45% of inhibition compared to diclofenac sodium of 56% followed by petroleum ether fractions of 49.69% and 39.39% at the same doses. The extracts did not produce any significant antinociceptive activity in tail flick test except standard morphine. When studied on yeast induced pyrexia, methanol and petroleum ether fractions significantly lowered the rectal temperature time dependently in a manner similar to standard drug paracetamol and distinctly more significant (P<0.001 after second hour. These findings suggest that the root extracts of S. grossus possess significant peripherally acting analgesic potential and antipyretic property. The phytochemical screening showed the presence of flavonoids, alkaloids, and tannins.

    Clove oil of Eugenia caryophyllata (Myrtaceae) is a light yellowish fluid obtained from dried flower buds. Clove oil is used traditionally to relieve toothache. The aim of the present work was to study the anti-inflammatory, antinociceptive and antipyretic potential of clove oil in mice. Analgesic activity was examined using acetic-acid-induced abdominal constrictions and the hot plate test. Carrageenan-induced paw edema and brewer's-yeast-induced pyrexia were used to investigate the anti-inflammatory activity and the antipyretic effects, respectively. The oil was administered intraperitoneally (i.p.) at a dose of 33 mg/kg body weight and the effects were compared with reference drugs. In the antinociceptive test, mice treated with clove oil exhibited significantly decreased acetic-acid-induced writhing movements by a maximum of 87.7% (pscreening of the oil showed the presence of eugenol. The present findings demonstrate the potential pharmacological properties of clove oil and provide further a support for its reported use in folk medicine.

    Full Text Available Objective: To investigate the the analgesic, anti-inflammatory and antipyretic activities of the methanolic leaf extract of Maerua crassifolia in mice and rats. Methods: Acetic acid-induced writhing and tail immersion methods were used to assess analgesic activity, while xylene and carrageenan-induced paw oedema methods were used to evaluate the anti-inflammatory effect of the leaf extract. Yeast and amphetamine-induced pyrexia were used to investigate the antipyretic activity. The phytochemical analysis and oral acute toxicity of the methanolic leaf extract of Maerua crassifolia were also evaluated. Results: The leaf extract (100, 200, and 400 mg/kg showed a dose dependent and significant (P < 0.05 inhibition of pain in acetic acid-induced writhing and tail immersion tests. The extract also produced significant (P < 0.05 anti-inflammatory activity in both paradigms. A significant (P < 0.05 reduction in hyperpyrexia was also observed with the leaf extract. The phytochemical screening revealed the presence of alkaloids, flavonoids, terpenoids, tannins, steroids, resins, saponins and cardiac glycosides. The oral median lethal dose of the leaf extract was estimated to be greater than 5 000 mg/kg in rats. Conclusions: The findings confirmed its ethnomedical use in the treatment of pains and feverish conditions.

    Full Text Available Mangrove plants are specialised plants that grow in the tidal coasts of tropic and subtropic regions of the world. Their unique ecology and traditional medicinal uses of mangrove plants have attracted the attention of researchers over the years, and as a result, reports on biological activity of mangrove plants have increased significantly in recent years. This review has been set out to compile and appraise the results on antinociceptive, anti-inflammatory, and antipyretic activity of mangrove plants. While the Web of Knowledge, Google Scholar, and PubMed were the starting points to gather information, other pieces of relevant published literature were also adequately explored for this purpose. A total of 29 reports on 17 plant species have been found to report such activities. While 19 reports were on the biological activity of the crude extracts, 10 reports identified the active compound(s of various chemical classes of natural products including terpenes, steroids, and flavonoids. This review finds that antinociceptive, anti-inflammatory, and antipyretic activity appears to be widespread in mangrove plants.

    Spirulina spp. is a blue-green algae belongs to the family of Oscillatoriaceae, which having diverse biological activity. The aim of this current study was to evaluate and compare the anti-pyretic and anti-inflammatory activity of Spirulina platensis/SP and Spirulina lonar/SL extracts. In the anti-pyretic study, the ability to reduce the rectal temperature of rats induced pyrexia with 2g/kg Brewer's Yeast (BY) was performed. Rats were dosed either 2 or 4 mg/kg SP or SL. Rectal temperature was taken every hour for 8 hours. Results shown that there were significant dose-dependent (p<0.05) reduction of both treatments. However, SP treatment revealed faster reduction in rectal temperature. For anti-inflammatory activity, the reduction in the volume of paw edema induced by Prostaglandin E2 (100 IU/rat intraplantar) was measured. Rats were dosed orally with 2 or 4 mg/kg SP or SL. The paw edema was measured every 30 minutes for 4 hours using plethysmometer. Results had shown a significant dose dependent reduction in diameter of paw edema (p<0.05). The finding suggests that SP and SL extracts have anti-pyretic and anti-inflammatory properties. However, SP was found to be more effective than SL as anti-pyretic and anti-inflammatory agent.

    Due to the emergence of new pharmaceutical presentations of ibuprofen (40 mg/ml), an analysis was made on the use of antipyretics in pediatric outpatient in Spain. A cross-sectional, observational, descriptive study was carried out on a sample of children under 14 years old with treated febrile syndrome, seen in the Emergency Room of the Hospital General Universitario de Valencia from November 2012 to January 2013. Of the 217 children included, 144 were treated with paracetamol or ibuprofen, 69 received both drugs, and one received paracetamol and metamizol. There were 58.7% of exposures to paracetamol and 40.9% to ibuprofen. The parents decided the use of antipyretics in 63.2% of cases. In 98 exposures the dose was different from that authorized in the labeling of the drug (off-label use). Ibuprofen was used off-label in 40.2% of cases, mostly by underdosing (35.9%). Paracetamol was used off-label in 29.8% of cases, predominantly overdose (26.8%), with the difference being statistically significant. No significant differences were observed in the off-label use in either monotherapy or combined use. There were also no differences when antipyretics prescribed by doctors or given directly by parents were evaluated separately. The majority of children with treated febrile syndrome seen in the Emergency Room were receiving antipyretic drugs after a parental decision. Paracetamol is the most commonly used drug and one in three children received it simultaneously with ibuprofen. The antipyretics were used off label in one-third of the cases. Off label use of ibuprofen is increasing, and is probably due to the existence of different pharmaceutical presentations. Copyright © 2013 Asociación Española de Pediatría.

  18. Antipyretic efficacy and tolerability of oral ibuprofen, oral dipyrone and intramuscular dipyrone in children: a randomized controlled trial

    Directory of Open Access Journals (Sweden)

    Judith Prado

    Full Text Available CONTEXT AND OBJECTIVE: Dipyrone is a widely used over-the-counter antipyretic in Latin America, and elsewhere among Latin immigrants. Despite limited evidence, physicians often prescribe oral ibuprofen or intramuscular dipyrone as the most effective antipyretics. Our aim was to compare the antipyretic efficacy and tolerability of a single dose of oral ibuprofen, oral dipyrone or intramuscular dipyrone in febrile children. DESIGN AND SETTING: Randomized, single-blind clinical trial, at San Bartolomé Mother-Child National Teaching Hospital, Lima, Peru. METHODS: Children from six months to six years old with fever (rectal temperature: 38.3 to 39.8° C in the emergency ward between February and June 2003 were eligible. Seventy-five children were randomly assigned to receive a single dose of oral ibuprofen (10 mg/kg, oral dipyrone (15 mg/kg or intramuscular dipyrone (15 mg/kg. The primary outcome was mean temperature reduction after 30, 45, 60, 90 and 120 minutes. Secondary outcomes were fever-associated symptoms and clinical adverse events. RESULTS: Fever decreased by about 0.5° C after 45 minutes and by about 1.0° C after 120 minutes in all three groups. Mean temperatures were similar for the three groups at all times. There was a significant decrease in fever-associated symptoms for all groups. Six patients (four receiving oral dipyrone and two receiving ibuprofen were withdrawn because of vomiting within 20 minutes after first dose of study medication. One patient assigned to oral ibuprofen presented transient urticaria. CONCLUSIONS: Antipyretic efficacy and tolerability were similar for oral ibuprofen, oral dipyrone and intramuscular dipyrone. Oral antipyretics seem more appropriate for feverish children.

    Full Text Available Qingkailing injection (QKLI is a modern Chinese medicine preparation derived from a well-known classical formulation, An-Gong-Niu-Huang Wan. Although the clinical efficacy of QKLI has been well defined, its severe adverse drug reactions (ADRs were extensively increased. Through thorough attempts to reduce ADR rates, it was realized that the effect-based rational use plays the key role in clinical practices. Hence, the pharmacokinetic-pharmacodynamic (PK-PD model was introduced in the present study, aiming to link the pharmacokinetic profiles with the therapeutic outcomes of QKLI, and subsequently to provide valuable guidelines for the rational use of QKLI in clinical settings. The PK properties of the six dominant ingredients in QKLI were compared between the normal treated group (NTG and the pyrexia model group (MTG. Rectal temperatures were measured in parallel with blood sampling for NTG, MTG, model control group (MCG, and normal control group (NCG. Baicalin and geniposide exhibited appropriate PK parameters, and were selected as the PK markers to map the antipyretic effect of QKLI. Then, a PK-PD model was constructed upon the bacalin and geniposide plasma concentrations vs. the rectal temperature variation values, by a two-compartment PK model with a Sigmoid Emax PD model to explain the time delay between the drug plasma concentration of PK markers and the antipyretic effect after a single dose administration of QKLI. The findings obtained would provide fundamental information to propose a more reasonable dosage regimen and improve the level of individualized drug therapy in clinical settings.

    Full Text Available Dried coarsely powdered material from the stem woods of Dracaena loureiri Gagnep (D loureiri has extracted with hexane and methanol to give hexane and methanol extracts, respectively. The methanol extract was roughly separated into four fractions. They were methanol, methanol + water, chloroform and ethyl acetate fractions. The effects of the methanol extract, hexane extract, methanol fraction, methanol + water fraction, ethyl acetate fraction and chloroform fraction on nociceptive response using writhing, hot plate and formalin tests in mice and the antipyretic activity in yeast-induced fever in rats, were examined. General behavior was also examined using pentobarbital-induced sleep in mice. The LD5 0 value of intraperitoneally injected the methanol extract, hexane extract, methanol fraction, ethyl acetate fraction and chloroform fraction in mice was 1.67 g/kg, >7 g/kg, 739.73 mg/kg, 489.77 mg/kg and 1.67 g/kg, respectively. Oral administration of the methanol extract and methanol fraction of D. loureiri (100-400 mg/kg dose de- pendently decreased the number of writhings and stretchings induced by acetic acid and licking activity of the late phase in the formalin test. All extracts or fractions of D. loureiri had no effects on heat-induced pain in mice. Only the methanol fraction of D. loureiri suppressed yeast-induced fever in rats. Neither extracts nor fractions affected paw edema induced by carrageenin in rats. The methanol extract of D. loureiri (100- 400 mg/kg, p.o. prolonged the duration of pentobarbital-induced sleep in mice. These results suggest that the methanol extract and the methanol fraction of D. loureiri possess analgesic effect. Only the methanol fraction of the extract exhibited antipyretic effect.

    Fever in children is a common and usually benign symptom. It is known that antipyretic treatment is ineffective in the prevention of simple febrile seizures. Caregivers' administration of antipyretic medications to children has been reported, but data concerning the formulations used, actual doses administered, and effects of ethnicity and socioeconomic status on administration practices are incomplete. The aim of this study was to identify the factors affecting antipyretic administration (higher-than-recommended doses in particular) by caregivers to their febrile children in 2 differing cultural-ethnic backgrounds. This cross-sectional survey study, conducted from January to March 2002, was part of a larger, ongoing survey study of the differences in care givers' knowledge, beliefs, and attitudes concerning children's fever in the 2 major cultural-ethnic groups in the Negev District in Israel: Jews and Bedouin Moslems. It was conducted at the Pediatric Emergency Department (PED), Soroka Medical Center, Beer-Sheva, Israel. A structured questionnaire was administered to Jewish and Bedouin Moslem parents or usual caregivers of young (age, 0-60 months) children attending the PED due to fever. Each child's weight was obtained from the PED medical record. After completion of the interview, the reported antipyretic dose per kilogram of body weight was calculated. Less-than-recommended dose was defined as 16.5 mg/kg for acetaminophen and >11 mg/kg for ibuprofen. The caregivers of a total of 201 children (mean [SD] age, 20 [17] months; mean [SD] weight, 10.4 [4.0] kg) were included in the study. The study included 101 Jewish and 100 Bedouin Moslem caregivers. The proportion of people surveyed who were parents was 98%; grandmothers, 2%. Differences existed between the 2 cultural-ethnic groups in the source of knowledge regarding antipyretic use in children (a significantly larger proportion of Jewish caregivers received their knowledge concerning antipyretic use from

    As a part of ongoing studies in developing new potent anti-inflammatory and analgesic agents, a series of novel 6-methoxy naphthalene derivatives was efficiently synthesized and characterized by spectral and elemental analyses. The newly synthesized compounds were evaluated for their anti-inflammatory activities using carrageenin-induced rat paw edema model, analgesic activities using acetic acid induced writhing model in mice and anti-pyretic activity using yeast induced hyperpyrexia method as well as ulcerogenic effects. Among the synthesized compounds, thiourea derivative (6a, e) exhibited higher anti-inflammatory activity than the standard drug naproxen in reduction of the rat paw edema (88.71, 89.77%) respectively. All of the non-carboxylic tested compounds were found to have promising anti-inflammatory, analgesic and antipyretic activity, while were devoid of any ulcerogenic effects. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Background: Clove oil of Eugenia caryophyllata (Myrtaceae is a light yellowish fluid obtained from dried flower buds. Clove oil is used traditionally to relieve toothache. Aim: The aim of the present work was to study the anti-inflammatory, antinociceptive and antipyretic potential of clove oil in mice. Methods: Analgesic activity was examined using acetic-acid-induced abdominal constrictions and the hot plate test. Carrageenan-induced paw edema and brewer's-yeast-induced pyrexia were used to investigate the anti-inflammatory activity and the antipyretic effects, respectively. The oil was administered intraperitoneally (i.p. at a dose of 33 mg/kg body weight and the effects were compared with reference drugs. Results: In the antinociceptive test, mice treated with clove oil exhibited significantly decreased acetic-acid-induced writhing movements by a maximum of 87.7% (p<0.01 compared with a decrease of 77.7% (p<0.01 in response to aspirin injection (100 mg/kg, intraperitoneal, i.p.. Similarly, in the hot plate test, clove oil significantly increased the reaction latency to pain after 60 min by 82.3% (p<0.05 compared with morphine value of 91.7% (p<0.01. In addition, clove oil and indomethacin produced anti-inflammatory effects, as demonstrated by respectively 50.6% (p<0.05 and 70.4% (p<0.01 inhibition of mouse paw edema induced by carrageenan. Furthermore, clove oil significantly attenuated the hyperthermia induced by yeast at ΔT-max by 2.7°C (p<0.001, and time of peak effects was 30–180 min compared with a paracetamol value ΔT-max of 3.2°C (p<0.001. The estimated i.p. LD50 of clove oil was 161.9 mg/kg. Phytochemical screening of the oil showed the presence of eugenol. Conclusion: The present findings demonstrate the potential pharmacological properties of clove oil and provide further a support for its reported use in folk medicine.

    Full Text Available Background Many parents consider fever a disease with the continuation of fever phobia and overuse of antipyretics to reduce it. Aims Identifying Kuwaiti parent’s knowledge of their children’s fever and determining their patterns of use of Over-the- Counter- Antipyretics. Methods A descriptive cross-sectional study in which we have recruited 614 Kuwaiti mothers of well children aged between six months and five years. Data was collected over six-months from September 2015 to March 2016, using a self-administered questionnaire. Results A total of 614 mothers participated in the study, with a response rate of 94.5 per cent. Twenty-seven per cent (166 of them considered a temperature ≤38.5°C to be a high- grade fever, with the level of education significantly influenced mothers’ reports of high-grade fever (F=4.68, df.=4, P=0.001, n=207. Almost all the parents believed that heat could cause harm, and 48 per cent (294 of them stated that fever is very harmful. Fifty-three per cent of mothers (309 would give antipyretic medication when body temperature is ≤38°C. Sixty-one per cent (375 of the mothers had alternated antipyretic paracetamol and ibuprofen. Forty-five per cent (274 of parents think that antipyretics are without potential harm. Level of education had a positive impact on the perception of fever [χ2 (df=8=70.68, p<0.001]. Usual practices targeted temperature reduction using antipyretics by 53.7 per cent. Conclusion Mothers have an imperfect knowledge of fever. Fever phobia is widespread, leading to an overuse of antipyretics.

    Nefang is a polyherbal anti-malarial composed of Mangifera indica ( MiB and MiL; bark and leaf), Psidium guajava ( Pg ), Carica papaya ( Cp ), Cymbopogon citratus ( Cc ), Citrus sinensis ( Cs ) and Ocimum gratissimum ( Og ) (leaves). Previous studies have demonstrated its in vitro and in vivo antiplasmodial activities, antioxidant properties and safety profile. This study aimed at evaluating the antipyretic, anti-inflammatory and antinociceptive activities of the constituent plants of Nefang which are relevant to the symptomatic treatment of malaria fever. Antipyretic activities were determined by the D-Amphetamine induced pyrexia and Brewer's Yeast induced hyperpyrexia methods. Anti-inflammatory activities were investigated using the carrageenan-induced rat paw edema method. Antinociceptive activities were determined by mechanical nociception in the tail pressure and thermal nociception in the radiant heat tail flick and hot plate methods. Data was analysed using the one way ANOVA followed by Neuman-Keuls multiple comparison test. Best percentage inhibition of induced pyrexia (amphetamine/brewer's yeast; p < 0.05) was exhibited by Cc (95/97) followed by Og (85/94), MiL (90/89), MiB (88/84) and Cs (82/89). Cc and Og exhibited comparable activities to paracetamol (100/95). Anti-inflammatory studies revealed paw edema inhibition (%) as follows (p < 0.05): Indomethacin (47), MiL (40), Cp (30), MiB (28) and Og (22), suggesting best activity by MiL. Antinociceptive studies revealed significant (p < 0.01) pain inhibition (%) as follows: Paracetamol (97), Og (113), MiL (108), Pg (84) and MiB (88). Og and MiL exhibited the best activities. The results obtained suggest that the constituent plants possess biologically active compounds with antipyretic, anti-inflammatory and antinociceptive activities. These activities are essential in the symptomatic treatment of malaria fever, thereby justifying the folk use of Nefang. This would be useful in its subsequent development for

    Full Text Available A series of schiff base derivatives of 4-aminophenazone (4APZ-1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one with different aldehydes were synthesized. The synthetic compounds were screened for their anti-inflammatory, analgesic and antipyretic activities. The characterization of synthesized compounds was carried out by 1H NMR, 13C NMR and MS. Carrageenan-induced paw oedema (CIPO and histamine induced paw oedema (HIPO methods were used to determine the anti-inflammatory activity of commercial sample of 4APZ and its synthesized schiff bases in mice. The anti-inflammatory activity was in the order of 4APZAB > 4APZBB > 4APZCB > 4APZVn and all the test compounds exhibited considerable dose dependent inhibition of the paw oedema. The effect of the compounds on membrane stabilization was also determined which showed that compounds 4APZ (120 and 240 mg/kg doses, 4APZAB (160 mg/kg and 4APZVn (600 mg/kg produced highly significant inhibition (P  4APZBB > 4APZVn > 4APZCB. Moreover, phenobarbitone-induced sleeping time (PIST in mice was also studied but only 600 mg/kg of 4APZVn significantly increased the duration of induced sleep which also suggested its sedative property. Brewer’s yeast was used to induce fever in rabbits and analysed the compounds for their antipyretic activity. Different doses of 4APZ for different time durations (240 mg/kg-after 1 h, 120 and 240 mg/kg doses-after 2 h produced highly significant (P < 0.001 inhibition of hyperpyrexia. Other compounds showed good antipyretic activity after 2, 3 and 4 h.

    Full Text Available The objective of this study was to determine the effect of eight 5-hydroxy-5-trifluoromethyl-4,5-dihydro-1H-1-carboxyamidepyrazoles (TFDPs on rat body temperature and baker’s yeast-induced fever. TFDPs or vehicle (5% Tween 80 in 0.9% NaCl, 5 mL/kg were injected subcutaneously and rectal temperature was measured as a function of time in 28-day-old male Wistar rats (N = 5-12 per group. Antipyretic activity was determined in feverish animals injected with baker’s yeast (Saccharomyces cerevisiae suspension, 0.135 mg/kg, 10 mL/kg, ip. 3-Ethyl- and 3-propyl-TFDP (140 and 200 μmol/kg, respectively, 4 h after yeast injection attenuated baker’s yeast-induced fever by 61 and 82%, respectively. These two effective antipyretics were selected for subsequent analysis of putative mechanisms of action. We then determined the effects on cyclooxygenase-1 and -2 (COX-1 and COX-2 activities on 1,1-diphenyl-2-picrylhydrazyl (DPPH oxidation in vitro, on tumor necrosis factor-α (TNF-α and interleukin-1β (IL-1β levels and on leukocyte counts in the washes of peritoneal cavities of rats injected with baker’s yeast. While 3-ethyl- and 3-propyl-TFDP did not reduce baker’s yeast-induced increases of IL-1β or TNF-α levels, 3-ethyl-TFDP caused a 42% reduction in peritoneal leukocyte count. 3-Ethyl- and 3-propyl-TFDP did not alter COX-1 or COX-2 activities in vitro, but presented antioxidant activity in the DPPH assay with an IC50 of 39 mM (25-62 and 163 mM (136-196, respectively. The data indicate that mechanisms of action of these two novel antipyretic pyrazole derivatives do not involve the classic inhibition of the COX pathway or pyrogenic cytokine release.

    Full Text Available Cleome scaposa has been associated with the prevention of many diseases as fever, abdominal complaints and cancer. But its antipyretic effect is not reported so far. The aim of this study was to assess the efficacy of C. scaposa in reducing temperature in Baker's yeast-induced fever model of rabbits. Rabbits were randomized into 4 groups (n = 24. Fever was induced in by Saccharomyces cerevisae (3 mL/kg of 10% suspension subcutaneous in all study groups. Afterward, group 1, 2, 3 and 4 were orally administered with paracetamol 150 mg/kg b. wt., distilled water, C. scaposa 250 and 500 mg/kg b. wt. respectively. 500 mg/kg dosage was selected after dose fixation study. The standard control was paracetamol. Rectal temperature was recorded with the help of a digital thermometer. ANOVA followed by post hoc test was applied for statistical analysis of results. Results of the study indicate that C. scaposa possesses antipyretic activity comparable to that of standard drug paracetamol as it exhibited comparable antipyretic potential against baker's yeast-induced fever in rabbits. This study confirms the traditional use of C. scaposa in fever. So, it can be an alternative therapeutic choice in fever. However, specific constituents responsible for its antipyretic activity should be evaluated.

    Introduction Fever is frequently observed in critically ill patients. An independent association of fever with increased mortality has been observed in non-neurological critically ill patients with mixed febrile etiology. The association of fever and antipyretics with mortality, however, may be different between infective and non-infective illness. Methods We designed a prospective observational study to investigate the independent association of fever and the use of antipyretic treatments with mortality in critically ill patients with and without sepsis. We included 1,425 consecutive adult critically ill patients (without neurological injury) requiring > 48 hours intensive care admitted in 25 ICUs. We recorded four-hourly body temperature and all antipyretic treatments until ICU discharge or 28 days after ICU admission, whichever occurred first. For septic and non-septic patients, we separately assessed the association of maximum body temperature during ICU stay (MAXICU) and the use of antipyretic treatments with 28-day mortality. Results We recorded body temperature 63,441 times. Antipyretic treatment was given 4,863 times to 737 patients (51.7%). We found that treatment with non-steroidal anti-inflammatory drugs (NSAIDs) or acetaminophen independently increased 28-day mortality for septic patients (adjusted odds ratio: NSAIDs: 2.61, P = 0.028, acetaminophen: 2.05, P = 0.01), but not for non-septic patients (adjusted odds ratio: NSAIDs: 0.22, P = 0.15, acetaminophen: 0.58, P = 0.63). Application of physical cooling did not associate with mortality in either group. Relative to the reference range (MAXICU 36.5°C to 37.4°C), MAXICU ≥ 39.5°C increased risk of 28-day mortality in septic patients (adjusted odds ratio 8.14, P = 0.01), but not in non-septic patients (adjusted odds ratio 0.47, P = 0.11). Conclusions In non-septic patients, high fever (≥ 39.5°C) independently associated with mortality, without association of administration of NSAIDs or

Extensive studies have been done in children comparing the efficacy of various antipyretics. However, studies on the efficacy of antipyretic drugs in adults are very scarce. To the best of our knowledge, no controlled trial has been carried out comparing the antipyretic efficacy of paracetamol (oral and intravenous and intramuscular diclofenac in adults. Methods: In this parallel-group, open-label trial, participants aged 14–75 years presenting with fever who had a temperature of more than 38.5°C were enrolled and treated. Participants were randomly allocated to receive treatment with 1,000 mg oral paracetamol (n = 145, 1,000 mg intravenous paracetamol (n = 139, or 75 mg intramuscular diclofenac (n = 150. The primary outcome was degree of reduction in mean oral temperature at 90 minutes. The efficacy of diclofenac versus oral and intravenous paracetamol was assessed by superiority comparison. Analysis was done using intention to treat principles.Results: After 90 minutes, all three groups showed a significant reduction in mean temperature, with intramuscular diclofenac showing the greatest reduction (−1.44 ± 0.43, 95% confidence interval [CI] −1.4 to −2.5 and oral paracetamol the least (−1.08 ± 0.51, 95% CI −0.99 to −2.2. After 120 minutes, there was a significant difference observed in the mean change from baseline temperature between the three treatment groups (P < 0.0001. Significant changes in temperature were observed in favor of intramuscular diclofenac over oral and intravenous paracetamol at each time point from 60 minutes through 120 minutes inclusive.Conclusion: Both intramuscular diclofenac and intravenous paracetamol showed superior antipyretic

    Full Text Available A methanolic extract from Senna garrettiana (S. garrettiana heartwood was prepared and then a fractionation process was performed to obtain hexane, dichloromethane, ethyl acetate, and aqueous fractions. An antinociceptive screening of each fraction was carried out using the acetic acid-induced writhing in mice. Among all the fractions, the ethyl acetate fraction showed the highest activity on the writhing test. The ethyl acetate fraction was separated to obtain a piceatannol-rich extract. The S. garrettiana extract contains 11.70 % w/w and 39.16 % w/w piceatannol in the ethyl acetate fraction and the piceatannol-rich extract, respectively. The analgesic activities of the ethyl acetate fraction (50, 100 and 200 mg/kg and the piceatannol-rich extract (10, 20 and 40 mg/kg were evaluated by the acetic acid-induced writhing test, hot-plate test and formalin test. The antipyretic activity of these extracts was assessed on yeast’s-induced pyrexia in rats. The acute toxicity was also investigated. In the acute toxicity study, no lethality was observed after the oral administration of methanolic extract of S. garrettiana heartwood even at a high dose of 5 g/kg in mice. The oral administration of the ethyl acetate fraction decreased the number of writhings in a dose dependent manner with 54.9 %, 68.5 %, and 71.0 % inhibition, respectively. A similar result was also observed after the oral administration of the piceatannol-rich extract with 53.1%, 69.2% and 80.3% inhibition, respectively. In the formalin test, either the ethyl acetate fraction or the piceatannol-rich extract significantly diminished the licking time in both the early and late phases. Neither the ethyl acetate nor the piceatannol-rich extract had any effect on heat-induced pain. The ethyl acetate fraction at the same dosage range significantly decreased the rat rectal temperature at 2, 3 and 4 hrs. The piceatannol-rich extract at a dose of 20 and 40 mg/kg suppressed the rectal temperature

    Melicope lunu-ankenda (Gaertn.) T.G. Hartley is used in Indian traditional medicine for fever, improving complexion and as a tonic. Previous studies have isolated fungicidal, antifeedant, anti-inflammatory and immunomodulatory compounds from Melicope lunu-ankenda. This study is aimed at the isolation and biological activity screening of potential molecules from the volatile oils and extracts of Melicope lunu-ankenda in the light of traditional applications. Volatile oil of Melicope lunu-ankenda leaves was isolated by hydrodistillation, characterized by GC-FID, GC-MS, LRI determination, Co-GC and database searches. Major chromene-type compounds in Melicope lunu-ankenda leaf oil, evodione and leptonol, were isolated by preparative TLC and characterized by UV-Vis, IR, 1H-, 13C-, 13C-DEPT NMR and EIMS. They were also isolated from the petroleum ether and acetone extracts of the leaves of Melicope lunu-ankenda by column chromatography in petroleum ether-ethyl acetate. Their contents in leaf oil, leaf and inflorescence extracts were estimated by HPTLC. Antipyretic (Baker's yeast-induced fever test), analgesic (acetic acid-induced writhing, tail immersion assays), anti-inflammatory (carrageenan-induced paw edema) and in vitro antioxidant (DPPH radical, superoxide radical scavenging) activities of evodione and leptonol were tested. Gas chromatographic analyses found 50.7% monoterpene hydrocarbons, 0.4% oxygenated monoterpenes, 3.2% sesquiterpene hydrocarbons, 0.7% oxygenated sesquiterpenes and 43.7% chromene-type compounds in Melicope lunu-ankenda leaf oil, with evodione (20.2%) and leptonol (22.5%) as its two major constituents. HPTLC estimations in the petroleum ether, acetone extracts (leaf, inflorescence) and leaf oil found evodione 1.0% (dr. wt., leaf), 1.1% (inflorescence), 0.04% (fr. wt. leaves, leaf oil), and leptonol 0.3% (leaf), 0.3% (inflorescence) and 0.04% (leaf oil). Leptonol (200 mg/kg) showed good antipyretic activity. DPPH radical scavenging assay found

    Anti-inflammatory, analgesic, and anti-pyretic activities of orally administered etofenamate, the diethylene glycol ester of flufenamic acid, were investigated in experimental animals. Against acetic acid-induced vascular permeability in mice and ultra-violet light-induced erythema in guinea pigs, etofenamate produced a dose related inhibition at doses of 40--320 mg/kg and 5--20 mg/kg, respectively. In rats, felt-pellet-induced granuloma formation and adjuvant-induced arthritis were significantly inhibited by repeated administration of etofenamate at doses of 20 mg/kg/day for 5 days and 40 mg/kg/day for 21 days, respectively. Etofenamate showed an inhibitory activity on the squeak response caused by flexing and extending the silver nitrate-induced arthritic joint in rats; and it produced a dose related anti-writhing activity at doses of 50--300 mg/kg and 10--80 mg/kg in mice and rats, respectively, in the acetic acid-induced writhing test. Etofenamate showed a significant anti-pyretic activity at doses of 0.2 mg/kg or more. These potencies of etofenamate were 0.5 to 1.6 times those of flufenamic acid. In particular, the anti-erythema, anti-arthritis, and anti-pyretic activities of etofenamate were approximately equivalent to or superior to those of flufenamic acid. From these results, it was suggested that etofenamate given orally, like other non-steroidal anti-inflammatory drugs, showed anti-inflammatory, analgesic, and anti-pyretic activities in experimental animals.

    Full Text Available With the increase in reports of the failure of Paracetamol as antipyretic in pediatric patients and the increase in the use of Mefenamic acid, the study was undertaken to recommend best among the bothantipyretics by comparing the efficacy and tolerability of both these drugs.Methods-It was a prospective, active treatment controlled study with follow up to 72 hours done over a period of 2 months after the Institutional Ethical committee approval. Total 124 pediatric patients with fever admitted to Pravara Rural Hospital, Loni having a body temperature >38.5 and fulfilling the inclusion and exclusion criteria were included. Patients included were categorized into two groups –group A and group B and administered Paracetamol and Mefenamic acid in the doses 15 mg/kg and 4 mg/kg body weight respectively. The parameters essential for comparing the efficacy and tolerability were observed andrecorded. The collected data were subjected to ‘paired t test’ of significance and was analyzed statistically.Results-Both drugs significantly decreased body temperature in pediatric patients with fever. The antipyretic efficacy of Mefenamic acid was highly significant than Paracetamol (<0.05. No significant differences in adverse effects were noted in both the groups. Conclusion-Mefenamic acid was found to be more effective and equally tolerable than paracetamol as an antipyretic in pediatric patients with febrile illness and can be the best alternative to paracetamol.

    Full Text Available The effects of the ethanol and aqueous extracts from the rhizome of Dioscorea membranacea Pierre (D. membranacea on inflammatory response using carrageenin-induced paw edema in rats, were examined. Antinociceptive activity using writhing, hot plate and formalin test in mice and the antipyretic activity in yeast-induced fever in rats, were also examined. Oral administration of the ethanol extract at the dose of 1600 mg/kg significantly decreased the paw edema induced by carrageenin in rats. The aqueous extract (1600 mg/kg also significantly suppressed the carrageenin-induced paw edema in rats. The ethanol extract had no significant effects on antinociceptive response in writhing, formalin and hot plate tests and antipyretic activities in yeast-induced fever in rats. No significant effects on writhing test and yeast-induced fever were observed after oral administration of the aqueous extract in experimental animals. These results suggest that the ethanol and aqueous extracts of D. membranacea rhizome possess anti-inflammatory action but no analgesic or antipyretic actions and their anti-inflammatory action may act at some site(s of action or inhibit of some inflammatory mediators, which is different from the action of aspirin.

    Full Text Available Macrosiphonia velame (Apocynaceae, popularly known as "velame-branco", is mainly used for treating inflammatory conditions. The antiinflammatory, antinociceptive and antipyretic effects of the hydroethanolic extract of the xylopodium from M. velame (HEMv were evaluated using several animal models. HEMv showed low acute oral toxicity with LD50 of 4.176 ± 218.5 mg/kg in mice. In tests of carrageenan and dextran-induced paw edema and carrageenan-induced pleurisy in rats, and croton oil-induced cutaneous dermatitis in mice, HEMv presented systemic and topical antiinflammatory activities. In experiments of nociception induced by acetic acid, formalin and capsaicin in mice, the HEMv evidenced an antinociceptive effect, being active against both inflammatory and neurogenic pain. Additionally, the HEMv prevented brewer's yeast-induced pyrexia in rats. It is likely that the pharmacologic mechanism of HEMv may involve the inhibition of different mediators of the inflammatory response, such as histamine, serotonin, prostaglandins and leukotrienes. A preliminary phytochemical study was also undertaken on HEMv, which revealed the presence of flavonoids, phenolic compounds, pentacyclic triterpenoids, saponins, coumarins, catechins, tannins, and alkaloids. Taken together, these results suggest that M. velame extract has antiinflammatory, antinociceptive and antipyretic properties and further validate the traditional use of this plant in inflammatory conditions.Macrosiphonia velame (Apocynaceae, conhecida popularmente como velame-branco, é utilizada no tratamento de inflamações.

    Full Text Available The experiment was conducted to study the activity of ethanol extract of belimbing wuluh (EEBW as antipyretic. Fever induction was done by using difteri pertusis tetanus (DPT vaccine intramuscularly at a dose of 0.1 mL/100 g BW. Male white rat strain spraque dawley with range of weight by 200 to 300 g was used in this research.Fifteen experimental rats were used to explore the specific time of fever (time of early fever and time of peak fever which were divided in 2 treatments, i.e. 10 experimental rats with DPT vaccine injection and 5 experimental rats without DPT vaccine injection as control.Fourty experimental rats were used to study effectivity of EEBW as antipyretic which were grouped with factorial randomized design with 4 x 2 and 5 replications. The first factor was various substance administered which consisted of aquadest (control, EEBW 0.88 g/kg BW, EEBW 1.75 g/kg BW, and aspirin 0.004 g/kg BW.The second factor was time of fever detection, i.e. time of early stage fever and time of peak fever. The variable was measured with rectal temperature of the experimental rats by using digital thermometer (correction factor 0.01oC every 30 minutes. The data were analyzed with t-student dan general linear model (GLM. Increasing of rectal temperature of experimental rats with DPT injection began at 30 minutes post-DPT injection (time of early stage fever and reached time of peak fever at 210 minutes post-DPT injection. Ethanol extract of belimbing wuluh at dose of 1.75 g/kg BW administered at early fever lowered rectal temperature of the experimental rats compared to the other groups. It was concluded that the administration of EEBW at dose of 1.75 g/kg BW was effective combination in dose and time administration as an antipyretic.

    Full Text Available Cariniana rubra Miers (Lecythidaceae, popularly known as "jequitibá-vermelho'', is a large Brazilian tree whose bark is used in infusion and decoction for the treatment of inflammatory conditions. This study aims to assess the anti-inflammatory, antinociceptive, and antipyretic effects of Cariniana rubra methanolic stem bark extract (EM Cr using experimental animals. Anti-inflammatory activity of EM Cr was tested on carrageenan and dextran-induced rat paw edema, carrageenan-induced pleurisy in rats and acetic acid-increase vascular permeability in mice. Antinociceptive and antipyretic activities were evaluated using acetic acid-induced writhing, formalin and hot-plate tests in mice, as well as brewer's yeast-induced pyrexia in rats. The extract inhibitied carrageenan and dextran-induced edema, reduced exudate volume and leukocyte migration on the carrageenan-induced pleurisy and on the vascular permeability increase induced by acetic acid. The EM Cr inhibited nociception on the acetic acid-induced writhing and in the second phase of formalin test, and decreased rectal temperature. It was, however, inactive against thermal nociception.Phytochemical analysis with EM Cr showed the occurrence of saponins, triterpenes, sterols and phenolic compounds. Phytosterols (β-sitosterol, stigmasterol, pentacyclic triterpenes (α- and β-amyrin as a mixture, arjunolic acid, a phytosterol glycoside (sitosterol 3-O-β-D-glucopyranoside, and triterpenoid saponins (28-β-glucopyranosyl-23-O-acetyl arjunolic acid; 3-O-β-glucopyranosyl arjunolic acid and 28-O-[α-L-Rhamnopyranosyl-(1→2-β-glucopyranosyl]-23- O-acetyl arjunolic acid were the main identified compounds. It can be presumed that EM Cr caused their effects by inhibiting the liberation and/or action of different inflammatory mediators. These findings support the traditional use of Cariniana rubra preparations to treat inflammation.Cariniana rubra Miers (Lecythidaceae, popularmente conhecido como

    Olive oil was used in the past as a remedy for many diseases due to its unlimited benefits in health. This study was carried out to assess the analgesic, anti-pyretic and anti-inflammatory activities of extra virgin olive oil (EVOO) at a dose of 8 mL/kg body weight and to compare it with ibuprofen (IBU) as an individual drug therapy and in combination with two different doses of IBU (therapeutic dose 100 mg/kg and low dose 40 mg/kg), on different animal models in albino mice. A total of 132 adult healthy male Swiss albino mice were used in this study. The analgesic effect was assessed using acetic acid-induced writhing test. The antipyretic effect was evaluated by brewer's yeast-induced pyrexia, while the anti-inflammatory activity was assessed by two different models; the carrageenan-induced paw edema and the carrageenan-induced peritonitis in which the levels of total leukocyte count (TLC), neutrophil count, prostaglandin E2 (PGE2) and interferon gamma (INF-γ) were measured in the peritoneal exudates. The results revealed significant protection in all the treated groups; however, the combination of EVOO with IBU at its therapeutic dose showed superiority over the two compounds when used separately. Using EVOO with the therapeutic dose of IBU showed synergistic effect in controlling the cardinal signs of acute inflammation rather than using non-steroidal anti-inflammatory drugs alone. © 2017 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

    Bencha-Loga-Wichian (BLW) is a polyherbal antipyretic formulation that is comprised of Capparis micracantha, Clerodendrum indicum, Ficus racemosa, Harrisonia perforata, and Tiliacora triandra. A traditional medical textbook has documented the use of this formulation for the treatment of many types of fever, including malaria-like fever. Traditionally, BLW is composed of the root parts of those plants. However, in current practice, the stem parts are frequently substituted. Thus, this study aimed to evaluate the antiplasmodial activities of BLW and compare the efficacy between the stem and root parts. BLW formulations produced from either the stem or root parts of the various constituent plants as well as the stems or roots of the individual plants were separately extracted and tested against the chloroquine-sensitive (Pf3D7) and -resistant (PfW2) strains Plasmodium falciparum using flow cytometry. The cytotoxicity against peripheral blood mononuclear cells was evaluated using the WST-8 assay to determine the selectivity index (SI). The active compounds of BLW were isolated using antiplasmodial-guided isolation and quantified using Ultra-Performance Liquid Chromatography (UPLC). The stem and root parts of BLW and the individual plants exhibited antiplasmodial activities at the same levels with good SI values in the range of 3.55-19.74. The extracts of BLW exhibited promising antiplasmodial activity against both Pf3D7 (IC 50 10. We isolated tiliacorinine and yanangcorinine as the major active compounds (IC 50 BLW in the range of 0.57-7.66%, which correlated with the antiplasmodial activity. The concentrations of these compounds in BLW, at comparable efficacy, were much less than those at the IC50s for the single compounds alone. It suggested that synergistic interactions increased the antiplasmodial effects as well as alleviated the toxicity of the active compounds in BLW. This study described a promising antiplasmodial activity of BLW that had good selectivity and a

    Interest in the presence of pharmaceuticals in wastewater, in the water of our rivers and, to a lesser extent, in our drinking water, has been growing in recent decades. Many of these substances, currently classified as "emerging pollutants", are biologically active compounds and continuously released in effluents. As sewage treatment plants (STPs) are not adequately equipped to eliminate all of these substances completely, some are discharged directly into rivers. In Spain, as in most of its neighbouring countries, there is an elevated use of pharmaceuticals for the treatment of cardiovascular diseases (which are extremely prevalent among the older adult population) and anti-inflammatory medications, which are obtainable over the counter without a medical prescription. This study therefore sought to determine to what degree pharmaceuticals with the highest regional prescription and/or use rates, such as cardiovascular and analgesic/anti-inflammatory/antipyretic medications, were present in the principal rivers (Jarama, Manzanares, Guadarrama, Henares and Tagus) and tap-water samples of the Madrid Region (MR). Samples were taken downstream the discharge of 10 of the most important region's STPs and the most frequently used drugs in the region were analysed for. Of the 24 drugs analysed, 21 were detected at concentrations ranging from 2 ng L⁻¹ to 18 μg L⁻¹. The highest drug concentrations corresponded to ibuprofen, diclofenac, naproxen, atenolol, frusemide (furosemide), gemfibrozil and hydrochlorthiazide, and in most cases exceeded the amounts reported in the scientific literature. No traces of these groups of pharmaceuticals were detected in the drinking water analysed. On the basis of the high concentrations detected, we believe that an environmental surveillance system should be implemented to assess the continuous discharge of these pharmaceuticals and their possible ecotoxicological effects. At the same time, efforts to raise the awareness of the public

    1 The effect of acetylsalicylic acid (1 g), indomethacin (50 mg), and phenylbutazone (200 mg) on psychomotor skills was examined double blind on 180 volunteer students. Ninety students received ethyl alcohol (0.5 g/kg) and 90 subjects an equal volume of placebo drink in combination with the drugs. 2 Psychomotor skills were measured with a choice reaction test, two co-ordination tests, and a divided attention test, having correlation with traffic behaviour. The subjects assessed their feelings of performance by means of a rating scale. The tests were done 30, 90 and 150 min after the administration of the agents. 3 Acetylsalicylic acid proved inactive whereas both indomethacin and phenylbutazone impaired eye-hand co-ordination and divided attention. Acetylsalicylic acid did not interact with alcohol to a measurable extent whereas indomethacin in combination with alcohol proved less harmful than without it. The deleterious effects of phenylbutazone and alcohol were additive. 4 An impairment of psychomotor skills related to driving by indomethacin and phenylbutazone should be considered when prescribing these drugs to active out-patients.

    2017-01-01

    Full Text Available Introduction: Homoeopathy is a widely used, controversial alternative system of medicine. It is assumed that homoeopathic medicines are slower in action and does not work in acute conditions such as ‘fever’. The study aims to estimate the effectiveness of some homoeopathic remedies in fever and to compare their effects with Paracetamol. Materials and Methods: Baker's yeast fever model of rabbits was used in the study. Rabbits were divided into four different groups (n = 6. Rectal temperature was measured before and after fever induction hourly. After fever induction, medicines were administered orally. Paracetamol and Typhoidinum in 200C and 1M potencies were given orally. ANOVA followed by post hoc test was used for statistical analysis of results. The results were considered statistically significant at P ≤ 0.05. Results: Fever was induced in all the rabbits after 4 h of baker's yeast administration. The results of the study revealed the significant effectiveness of Typhoidinum in 200C and 1M potencies in baker's yeast-induced fever (P = 0.05. Typhoidinum in both potencies showed less significant results as compared to Paracetamol. However, all the medicines’ effects were significant compared to the negative control. Conclusion: Typhoidinum 200C and 1M worked against baker's yeast-induced fever. However, the results were slower and less significant than Paracetamol that might be due to lack of similarity of remedy picture and disease picture.

  11. Paracetamol in fever in critically ill patients-an update.

    Science.gov (United States)

    Chiumello, D; Gotti, M; Vergani, G

    2017-04-01

    Fever, which is arbitrary defined as an increase in body temperature above 38.3°C, can affect up to 90% of patients admitted in intensive care unit. Induction of fever is mediated by the release of pyrogenic cytokines (tumor necrosis factor α, interleukin 1, interleukin 6, and interferons). Fever is associated with increased length of stay in intensive care unit and with a worse outcome in some subgroups of patients (mainly neurocritically ill patients). Although fever can increase oxygen consumption in unstable patients, on the contrary, it can activate physiologic systems that are involved in pathogens clearance. Treatments to reduce fever include the use of antipyretics. Thus, the reduction of fever might reduce the ability to develop an efficient host response. This balance, between harms and benefits, has to be taken into account every time we decide to treat or not to treat fever in a given patient. Among the antipyretics, paracetamol is one of the most common used. Paracetamol is a synthetic, nonopioid, centrally acting analgesic, and antipyretic drug. Its antipyretic effect occurs because it inhibits cyclooxygenase-3 and the prostaglandin synthesis, within the central nervous system, resetting the hypothalamic heat-regulation center. In this clinical review, we will summarize the use of paracetamol as antipyretic in critically ill patients (sepsis, trauma, neurological, and medical). Copyright © 2016 Elsevier Inc.

This study was conducted to explore  the effective doses of ethanol extract of kipahit leaf (Tithonia diversifolia as an antipyretics. Twenty four male sprague–dawley white rats weighed150–200 g were divided into 6 groups and replicated 4 times. The experiment included  experimental rats without fever induction and without administration of antipyretic substance (control 0, experimental rats with induced fever without administration of antipyretic substance (negative control, experimental rats with induced fever and  ethanol extract of kipahit leaf (EEDK with various doses: 100 mg/kg BW (treatment 1, 200 mg/kg BW (treatment 2, 300 mg/kg BW (treatment 3, and 400 mg/kg BW (treatment 4. Fever was induced by injecting DTP–HB–Hib vaccines intramuscularly at a dose of 0.2 mL/200 g BW. Administration of EEDK was conducted orally at 90 minutes pos-injection of DPT–HB–Hib vaccines. The antipyretic effects of EEDK were observed by measuring rectal temperature by using digital thermometer (correction factor 0.1ºC in 0 minute (before the injection of DTP–HB–Hib or normal temperature, 90, 120, 150, and 180 minutes post–fever induction. The result showed that the administration of EEDK decreased rectal temperature as compared to negative control. The optimum doses of EEDK administration that decreased rectal temperature were 100 and 200 mg/kg BW. It is concluded that the EEDK has an effect.

    Antipyretic analgesics are commonly used to prevent and treat adverse events following immunizations. Current practice discourages routine use due to possible blunting of vaccine immune responses. We surveyed 150 parents/caregivers of recently vaccinated 6- and 15-month-old children to determine the prevalence of and beliefs regarding antipyretic analgesics use around vaccinations. 11% used them prophylactically, before vaccination. Use in the first 48 hours after vaccination was 64%, primarily to prevent and/or treat fever and pain. Acetaminophen was administered 2.6 times more frequently than ibuprofen. Ibuprofen was used more in the 15-month compared with the 6-month-old children (28% vs 7.4%, respectively, P = .001). The majority of caregivers disagreed with their use for fever (53%) or pain (59%). Antipyretic analgesic use, including prophylaxis, around vaccinations was common in our study population. Effective interventions are needed to target parents/caregivers to eliminate unnecessary antipyretic analgesic use around vaccination time and foster nonmedication alternatives.

    The antipyretic and hypothermic prodrug dipyrone prevents PGE2 -dependent and -independent fever induced by LPS from Escherichia coli and Tityus serrulatus venom (Tsv) respectively. We aimed to identify the dipyrone metabolites responsible for the antipyretic and hypothermic effects. Male Wistar rats were treated i.p. with indomethacin (2 mg·kg(-1) ), dipyrone, 4-methylaminoantipyrine (4-MAA), 4-aminoantipyrine (4-AA) (60-360 mg·kg(-1) ), 4-formylaminoantipyrine, 4-acethylaminoantipyrine (120-360 mg·kg(-1) ) or vehicle 30 min before i.p. injection of LPS (50 μg·kg(-1) ), Tsv (150 μg·kg(-1) ) or saline. Rectal temperatures were measured by tele-thermometry and dipyrone metabolite concentrations determined in the plasma, CSF and hypothalamus by LC-MS/MS. PGE2 concentrations were determined in the CSF and hypothalamus by elisa. In contrast to LPS, Tsv-induced fever was not followed by increased PGE2 in the CSF or hypothalamus. The antipyretic time-course of 4-MAA and 4-AA on LPS-induced fever overlapped with the period of the highest concentrations of 4-MAA and 4-AA in the hypothalamus, CSF and plasma. These metabolites reduced LPS-induced fever and the PGE2 increase in the plasma, CSF and hypothalamus. Only 4-MAA inhibited Tsv-induced fever. The higher doses of dipyrone and 4-MAA also induced hypothermia. The presence of 4-MAA and 4-AA in the CSF and hypothalamus was associated with PGE2 synthesis inhibition and a decrease in LPS-induced fever. 4-MAA was also shown to be an antipyretic metabolite for PGE2 -independent fever induced by Tsv suggesting that it is responsible for the additional antipyretic mechanism of dipyrone. Moreover, 4-MAA is the hypothermic metabolite of dipyrone. © 2014 The British Pharmacological Society.

    Full Text Available Background : Pain is an unpleasant and subjective sensation that results from a harmful sensorial stimulation, which alerts the body about current or potential damage to its tissues and organs. Fever is a complex physiological response triggered by infections or aseptic stimuli. Elevation in body temperature occurs when the concentration of prostaglandin E 2 (PGE 2 increases within parts of the brain. Triazole derivatives have been found to possess various pharmacological and biological activities, such as, anti-inflammatory, analgesics, antipyretic, and antifungal. Materials and Methods : Various 4-[{1-(arylmethylidene}-amino]-3-(4-pyridyl-5-mercapto-4H-1,2,4-triazole derivatives were synthesized by a sequence of reactions starting from isonicotinic acid hydrazide. The synthesized compounds were screened for in-vivo analgesic by the tail-flick method and anti-pyretic activities at a dose of 25 and 100 mg/kg body weight respectively. The antipyretic activity was evaluated using Brewer′s yeast induced pyrexia in rats. Fever was induced by subcutaneously injecting 20 ml/kg of 20% aqueous suspension of Brewer′s yeast in normal saline. Results and Discussion : The analgesic screening results revealed that the compounds 3b, 3c, and 3d exhibited excellent analgesic activity at 60 and 90 minutes compared to the standard drug (Analgin. Results revealed that the compounds 3a, 3e, and 3f significantly decreased the temperature of pyretic (P<0.001 rats at one, three and six hours after compound administration as compared to Aspirin (standard drug. Conclusion : Compounds 3b, 3c, and 3d exhibited significant analgesic activity comparable with the standard drug analgin, using the tail flick model. Compounds 3a, 3e, and 3f showed significant anti-pyretic activities comparable with the standard drug aspirin using the yeast-induced pyrexia model.

    Fever is a very common problem in pediatric age and is one of the most common reasons parents seek medical attention. We aimed to investigate beliefs, habits, and concerns of Turkish parents regarding their children's fever. We performed a cross-sectional survey which was conducted as face-to-face interviews by family physicians from April to June 2014 in family healthcare centers in nine different cities in Turkey. Parents with a child with fever aged between 0 and 14 years were interviewed. The participants were asked questions about sociodemographic data, the definition and measurement of fever, antipyretics, and other interventions used to reduce fever before presenting to the primary care center. A total of 205 parents participated in this study. Ninety-four parents (45.8%) measured fever with a thermometer prior to presentation. Only 36 parents (38%) used the thermometer correctly. Thirty-eight parents (18.5%) knew the correct temperature definition of fever for the measured site. A mercury-in-glass thermometer was the choice for most parents (78%) and preferred site for measurement was axillary region (85%). The fever was treated prior to arrival by 171 parents (83.4%). Paracetamol was the most frequently used antipyretic. Fifty-four parents (31.5%) failed to administer the correct antipyretic dose, and 73 parents (42.6%) failed to give the antipyretics at proper intervals. One hundred and fifty-three parents (67%) believed that if not treated fever could cause convulsions. We conclude that parents share important misconceptions about definition, treatment, and consequences of childhood fever and tend to treat fever before seeking medical care with a substantial rate of wrong doses and wrong intervals.

    Lafoensia pacari St. Hil. (Lythraceae) is used in traditional medicine to treat inflammation. Previously, we demonstrated the anti-inflammatory effect that the ethanolic extract of L. pacari has in Toxocara canis infection (a model of systemic eosinophilia). In this study, we tested the anti-inflammatory activity of the same L. pacari extract in mice injected intraperitoneally with beta-glucan present in fraction 1 (F1) of the Histoplasma capsulatum cell wall (a model of acute eosinophilic inflammation). We also determined the anti-oedematous, analgesic and anti-pyretic effects of L. pacari extract in carrageenan-induced paw oedema, acetic acid writhing and LPS-induced fever, respectively. L. pacari extract significantly inhibited leucocyte recruitment into the peritoneal cavity induced by beta-glucan. In addition, the L. pacari extract presented significant analgesic, anti-oedematous and anti-pyretic effects. Bioassay-guided fractionation of the L. pacari extract in the F1 model led us to identify ellagic acid. As did the extract, ellagic acid presented anti-inflammatory, anti-oedematous and analgesic effects. However, ellagic acid had no anti-pyretic effect, suggesting that other compounds present in the plant stem are responsible for this effect. Nevertheless, our results demonstrate potential therapeutic effects of L. pacari extract and ellagic acid, providing new prospects for the development of drugs to treat pain, oedema and inflammation.

    Artemisinin isolated from Artemisia annua is the most potent antimalarial against chloroquine resistant Plasmodium falciparum malaria. We previously reported that the ethanolic leaf extract of Artemisia vulgaris, an invasive weed and the only Artemisia species in Sri Lanka, possess both potent and safe antimalarial activity (in terms of antiparasitic properties) in a P. berghei murine malaria model. We report here a prototype study that investigated antidisease activities of A. vulgaris ethanolic leaf extract (AVELE) in a P. berghei ANKA murine malaria model that elicit pathogenesis similar to falciparum malaria. Profound thrombocytosis and thrombocytopenia in mice were detected in early-stage (Day 3), and at a later stage of infection (Day 6), respectively. Plasmodium berghei infected mice, 7 or 8 days post-infection reached end-stage disease with rapid drop in body temperature and usually die within 24 h, as a consequence of cerebral malaria. Three doses of the AVELE (500, 750 and 1000 mg/kg) were used to assess antidisease activity of A. vulgaris in terms of survival, effects on thrombocyte related pathology and end-stage disease, antipyretic activity, and antinociception, using standard methodology. The 1000 mg/kg dose of AVELE significantly increased survival, reversed the profound thrombocytopenia/ thrombocytosis (p ≤0.01), altered the end-stage disease (p ≤0.05), and manifested significant antipyretic and antinociceptive (p ≤0.05) activities. We conclude that a crude ethanolic leaf extract of A. vulgaris, showed potent antimalarial properties, in terms of antidisease activities; antipyretic activity, peripheral and central antinociception, increased survival, averted end-stage disease and reversed thrombocytopenia/thrombocytosis.

    Aspirin is chemopreventive; however, side effects preclude its long-term use. NOSH-aspirin (NBS-1120), a novel hybrid that releases nitric oxide and hydrogen sulfide, was designed to be a safer alternative. Here we compare the gastrointestinal safety, anti-inflammatory, analgesic, anti-pyretic, anti-platelet, and chemopreventive properties of aspirin and NBS-1120 administered orally to rats at equimolar doses. Gastrointestinal safety: 6h post-administration, the number and size of hemorrhagic lesions in stomachs were counted; tissue samples were frozen for PGE2, SOD, and MDA determination. Anti-inflammatory: 1h after drug administration, the volume of carrageenan-induced rat paw edemas was measured for 5h. Anti-pyretic: fever was induced by LPS (ip) an hour before administration of the test drugs, core body temperature was measured hourly for 5h. Analgesic: time-dependent analgesic effects were evaluated by carrageenan-induced hyperalgesia. Antiplatelet: anti-aggregatory effects were studied on collagen-induced platelet aggregation of human platelet-rich plasma. Chemoprevention: nude mice were gavaged daily for 25 days with vehicle, aspirin or NBS-1120. After one week, each mouse was inoculated subcutaneously in the right flank with HT-29 human colon cancer cells. Both agents reduced PGE2 levels in stomach tissue; however, NBS-1120 did not cause any stomach ulcers, whereas aspirin caused significant bleeding. Lipid peroxidation induced by aspirin was higher than that exerted by NBS-1120. SOD activity was significantly inhibited by aspirin but increased by NBS-1120. Both agents showed similar anti-inflammatory, analgesic, anti-pyretic, and anti-platelet activities. Aspirin increased plasma TNFα more than NBS-1120-treated animals. NBS-1120 was better than aspirin as a chemopreventive agent; it dose-dependently inhibited tumor growth and tumor mass. Copyright © 2015 Elsevier Inc. All rights reserved.

Gastrointestinal safety: 6h post-administration, the number and size of hemorrhagic lesions in stomachs were counted; tissue samples were frozen for PGE2, SOD, and MDA determination. Anti-inflammatory: 1h after drug administration, the volume of carrageenan-induced rat paw edemas was measured for 5h. Anti-pyretic: fever was induced by LPS (ip) an hour before administration of the test drugs, core body temperature was measured hourly for 5h. Analgesic: time-dependent analgesic effects were evaluated by carrageenan-induced hyperalgesia. Antiplatelet: anti-aggregatory effects were studied on collagen-induced platelet aggregation of human platelet-rich plasma. Chemoprevention: Nude mice were gavaged daily for 25 days with vehicle, aspirin or NBS-1120. After one week, each mouse was inoculated subcutaneously in the right flank with HT-29 human colon cancer cells. Both agents reduced PGE2 levels in stomach tissue; however, NBS-1120 did not cause any stomach ulcers, whereas aspirin caused significant bleeding. Lipid peroxidation induced by aspirin was higher than that exerted by NBS-1120. SOD activity was significantly inhibited by aspirin but increased by NBS-1120. Both agents showed similar anti-inflammatory, analgesic, anti-pyretic, and anti-platelet activities. Aspirin increased plasma TNFα more than NBS-1120-treated animals. NBS-1120 was better than aspirin as a chemopreventive agent; it dose-dependently inhibited tumor growth and tumor mass. PMID:26394025

    Kawasaki disease is the primary cause of acquired pediatric heart disease in developed nations. Timely diagnosis of Kawasaki disease incorporates transthoracic echocardiography for visualization of the coronary arteries. Sedation improves this visualization, but not without risks and resource utilization. To identify potential sedation criteria for suspected Kawasaki disease, we analyzed factors associated with diagnostically inadequate initial transthoracic echocardiography performed without sedation. This retrospective review of patients Kawasaki disease from 2009 to 2015 occurred at a medium-sized urban children's hospital. The primary outcome was diagnostically inadequate transthoracic echocardiography without sedation due to poor visualization of the coronary arteries, determined by review of clinical records. The associations of the primary outcome with demographics, Kawasaki disease type, laboratory data, fever, and antipyretic or intravenous immunoglobulin treatment prior to transthoracic echocardiography were analyzed. In total, 112 patients (44% female, median age 2.1 years, median BSA 0.54 m 2 ) underwent initial transthoracic echocardiography for suspected Kawasaki disease, and 99 were not sedated. Transthoracic echocardiography was diagnostically inadequate in 19 out of these 99 patients (19.2%) and was associated with age ≤ 2.0 years, weight ≤ 10.0 kg, and antipyretic use ≤ 6 hours before transthoracic echocardiography (all P Kawasaki disease. These factors should be considered when deciding which patients to sedate for initial Kawasaki disease transthoracic echocardiography. © 2018 Wiley Periodicals, Inc.

    Full Text Available Francesco Di Pierro,1 Alberto Zanvit,2 Maria Colombo3 1Scientific Department, Velleja Research, 2Biological Dentistry Department, Italian Stomatology Institute, 3ATS, District 5, Milan, Italy Abstract: Antipyretics and/or anti-inflammatory drugs along with a wait-and-see approach are the only treatments recommended in early acute otitis media (AOM or viral pharyngitis. Propolis has been widely investigated for its antibacterial, antiviral, and anti-inflammatory properties and could perhaps be administered as an add-on therapy during watchful waiting in AOM or for better control of symptoms in nonstreptococcal pharyngitis. However, propolis has well-known problems of poor solubility and low oral bioavailability. We therefore analyzed a proprietary propolis-based product (Propolisina® developed to overcome these limitations, in a retrospective, open-label, controlled study of Streptococcus pyogenes-negative children with a diagnosis of AOM or pharyngitis. Our results show that the use of propolis supplement for 72 hours lessens the severity of AOM and viral pharyngitis, reduces the use of antipyretics and anti-inflammatory drugs, and decreases the rate of evolution to tracheitis, bronchitis, and rhinosinusitis. Our study shows that propolis could be used as a safe add-on therapy in case of AOM and/or viral pharyngitis. Keywords: pediatric infections, cogrinding, bioavailability, propolis

    Full Text Available Abstract Background Fever is an extremely common sign in paediatric patients and the most common cause for a child to be taken to the doctor. The literature indicates that physicians and parents have too many misconceptions and conflicting results about fever management. In this study we aim to identify knowledge, attitudes and misconceptions of primary care physicians regarding fever in children. Methods This cross-sectional study was conducted in April-May 2010 involving primary care physicians (n=80. The physicians were surveyed using a self-administered questionnaire. Descriptive statistics were used. Results In our study only 10% of the physicians knew that a body temperature of above 37.2°C according to an auxiliary measurement is defined as fever. Only 26.2% of the physicians took into consideration signs and symptoms other than fever to prescribe antipyretics. 85% of the physicians prescribed antipyretics to control fever or prevent complications of fever especially febrile seizures. Most of the physicians (76.3% in this study reported that the height of fever may be used as an indicator for severe bacterial infection. A great majority of physicians (91.3% stated that they advised parents to alternate the use of ibuprofen and paracetamol. Conclusions There were misconceptions about the management and complications of fever. There is a perceived need to improve the recognition, assessment, and management of fever with regards to underlying illnesses in children.

    Cimicifuga rhizomes (CR) are used in the treatment of respiratory and cardiovascular diseases in traditional Chinese medicine, but their key effective components and mechanism of action have not yet been reported. In this study, the cardiac, antipyretic and sudorific effects of CR were evaluated using the toad heart failure in vitro model and mice fever and sweating in vivo models. Moreover, the UPLC/Q-TOF-MS-integrated β2-AR luciferase reporter gene assay system was used to screen the bioactive ingredients from CR extract, and the activity of this ingredient were verified using the above-mentioned in vitro and vivo models. Our results showed that CR had anti-heart failure, antipyretic and sweating effects, which could be antagonized by propranolol. On the other hand, cimicifugamide was screened as β2-AR agonist from CR and cimicifugamide could activate β1, 2-ARs more significantly than β3-AR in β-ARs selectivity assessment. The results not only revealed the key effective components and mechanism of CR in traditional use but also supplied a characteristic complementary ingredient for quality control of CR.

    Full Text Available The effects of the alkaloid extract from the leaves of Kopsia macrophylla Hk. f. K. (K. macrophylla on nociceptive response using writhing, hot plate and formalin test and the antipyretic activity in yeast-induced fever in mice, were examined. General behavior was also examined using pentobarbital-induced sleep in mice. The LD50 value of intraperitoneally injected K. macrophylla extract in mice was 318.46 mg/kg. Oral administration of K. macrophylla extract at the dose of 400 mg/kg significantly decreased the number of contortions and stretchings induced by acetic acid and licking activity of the late phase in the formalin test but not in the heat-induced pain in mice. The K. macrophylla extract (100-400 mg/kg, p.o. had no effect on fever induced by yeast in mice. The alkaloid extract of K. macrophylla prolonged the duration of pentobarbitalinduced sleep in mice. These results suggest that the alkaloid extract of K. macrophylla possesses analgesic action via peripheral pathway but no antipyretic activity.

    2012-01-01

    Salicylate, the active component of the common drug aspirin, has mild analgesic, antipyretic, and anti-inflammatory effects at moderate doses. At higher doses, however, salicylate temporarily induces moderate hearing loss and the perception of a high-pitch ringing in humans and animals. This phantom perception of sound known as tinnitus is qualitatively similar to the persistent subjective tinnitus induced by high-level noise exposure, ototoxic drugs, or aging, which affects ∼14% of the general population. For over a quarter century, auditory scientists have used the salicylate toxicity model to investigate candidate biochemical and neurophysiological mechanisms underlying phantom sound perception. In this review, we summarize some of the intriguing biochemical and physiological effects associated with salicylate-induced tinnitus, some of which occur in the periphery and others in the central nervous system. The relevance and general utility of the salicylate toxicity model in understanding phantom sound perception in general are discussed. PMID:22557950

    Full Text Available Paeonol is an active component of Moutan Cortex Radicis and is widely used as an analgesic, antipyretic, and anti-inflammatory agent in traditional Chinese medicine. We wanted to determine the role of paeonol in treating adult respiratory distress syndrome (ARDS. We established an acute lung injury (ALI model in Sprague-Dawley rats, which was similar to ARDS in humans, using intratracheal administration of lipopolysaccharide (LPS. The intraperitoneal administration of paeonol successfully reduced histopathological scores and attenuated myeloperoxidase-reactive cells as an index of polymorphonuclear neutrophils infiltration and also reduces inducible nitric oxide synthase expression in the lung tissue, at 16 h after LPS administration. In addition, paeonol reduced proinflammatory cytokines in bronchoalveolar lavage fluid, including tumor-necrosis factor-α, interleukin-1β, interleukin-6, and plasminogen-activated inhibition factor-1. These results indicated that paeonol successfully attenuates inflammatory and coagulation reactions to protect against ALI.

    Although limited publications address clinical management of symptomatic patients with rabies in intensive care units, the overwhelming majority of human rabies cases occur in the rural setting of developing countries where healthcare workers are few, lack training and drugs. Based on our experience, we suggest how clinicians in resource-limited settings can make best use of essential drugs to provide assistance to patients with rabies and their families, at no risk to themselves. Comprehensive and compassionate patient management of furious rabies should aim to alleviate thirst, anxiety and epileptic fits using infusions, diazepam or midazolam and antipyretic drugs via intravenous or intrarectal routes. Although the patient is dying, respiratory failure must be avoided especially if the family, after being informed, wish to take the patient home alive for funereal rites to be observed. Healthcare staff should be trained and clinical guidelines should be updated to include palliative care for rabies in endemic countries. © 2016 John Wiley & Sons Ltd.

    2017-01-01

    NSAIDs are the most largely used class of drugs in the world, due to their large use in many diseases, in particular for the systemic inflammatory diseases. Nevertheless, today NSAIDs are less used for some of these diseases, due to several side-effects correlated to these drugs. The antiinflammatory mechanism of NSAIDs consist in the inibhition of two forms of cyclooxygenase, namely COX-1 (its block contributes to an antiplatelet effect) and COX-2 (its block has a greater antiinflammatory, antipyretic and analgesic effect). The COX-2 inhibition might reduce the risk of gastrointestinal toxicity, but several studies have shown the cardiovascular side effects of this inhibition. Mechanisms of the cardiovascular side effects are controversial yet, so the aim of this document is to review side-effects profile of NSAIDs and, specifically, to investigate cardiovascular consequences of NSAIDs use in clinical practice.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are used extensively for analgesic and antipyretic treatments. In addition, NSAIDs reduce the risk and mortality to several cancers. Their mechanisms in anti-tumorigenesis are not fully understood, but both cyclooxygenase (COX)-dependent and -independent pathways play a role. We and others have been interested in elucidating molecular targets of NSAID-induced apoptosis. In this review, we summarize updated literature regarding cellular and molecular targets modulated by NSAIDs. Among those NSAIDs, sulindac sulfide and tolfenamic acid are emphasized in this review because these two drugs have been well investigated for their anti-tumorigenic activity in many different types of cancer.

    2013-01-01

    Full Text Available Nonsteroidal anti-inflammatory drugs (NSAIDs are the most highly prescribed drugs in the world. Their analgesic, anti-inflammatory, and antipyretic actions may be beneficial; however, they are associated with severe side effects including gastrointestinal injury and peptic ulceration. Though several approaches for limiting these side effects have been adopted, like the use of COX-2 specific drugs, comedication of acid suppressants like proton pump inhibitors and prostaglandin analogs, these alternatives have limitations in terms of efficacy and side effects. In this paper, the mechanism of action of NSAIDs and their critical gastrointestinal complications have been reviewed. This paper also provides the information on different preventive measures prescribed to minimize such adverse effects and analyses the new suggested strategies for development of novel drugs to maintain the anti-inflammatory functions of NSAIDs along with effective gastrointestinal protection.

    2014-01-01

    Full Text Available Prostatic diseases are characterized by increased activity of cytokines, growth factors, and cyclooxygenases- (COX- 1 and 2. Activation of COX-1 and COX-2 results in increased levels of prostaglandins and the induction of angiogenic, antiapoptotic and inflammatory processes. Inhibition of COX enzymes by members of the widely used nonsteroidal anti-inflammatory drug (NSAID class of drugs decreases prostaglandin production, and exerts a variety of anti-inflammatory, antipyretic, and antinociceptive effects. While numerous in vitro, in vivo, and clinical studies have shown that NSAIDs inhibit the risk and progression of prostatic diseases, the relationship between NSAIDs and such diseases remains controversial. Here we review the literature in this area, critically analyzing the benefits and caveats associated with the use of NSAIDs in the treatment of prostatic diseases.

    2012-04-01

    Full Text Available Salicylate, the active component of the common drug aspirin, has mild analgesic, antipyretic, and anti-inflammatory effects at moderate doses. At higher doses, however, salicylate temporarily induces moderate hearing loss and the perception of a high-pitch ringing in humans and animals. This phantom perception of sound known as tinnitus is qualitatively similar to the persistent subjective tinnitus induced by high-level noise exposure, ototoxic drugs or aging which affects ~14% of the general population. For over a quarter century, auditory scientists have used the salicylate toxicity model to investigate candidate biochemical and neurophysiological mechanisms underlying phantom sound perception. In this review, we summarize some of the intriguing biochemical and physiological effects associated with salicylate-induced tinnitus, some of which occur in the periphery and others in the central nervous system. The relevance and general utility of the salicylate toxicity model in understanding phantom sound perception in general are discussed.

    Onopordum illyricum L. is a medicinal plant used in the Mediterranean area as antipyretic for the treatment of respiratory and urinary inflammations and to treat skin ulcers. Repeated chromatographic purification of O. illyricum aerial parts led to the isolation of six known sesquiterpenes, which were evaluated for the inhibition of the pro-inflammatory transcription factors NF-κB and STAT3 and for the activation of the transcription factor Nrf2, which regulates the cellular antioxidant response. Structure-activity relationships were interpreted by the NMR-based cysteamine assay. The sesquiterpene lactone vernomelitensin significantly inhibited NF-κB and STAT3, showing also a significant Nrf2 activation. Accordingly, the cysteamine assay selected vernomelitensin as the most reactive of the isolated sesquiterpenes, identifying the α,β-unsaturated aldehyde moiety as responsible for the higher (re)activity.

    Acetaminophen is used as an analgesic and antipyretic agent. The aim of the study was evaluation of the effect of different polymers on rheological behavior of acetaminophen suspension. In order to achieve controlled flocculation, sodium chloride was added. Then structural vehicles such as carboxymethyl cellulose (CMC), polyvinyl pyrrolidone (PVP), tragacanth, and magnesium aluminum silicate (Veegum) were evaluated individually and in combination. Physical stability parameters such as sedimentation volume (F), redispersibility (n), and growth of crystals of the suspensions were determined. Also, the rheological properties of formulations were studied. The results of this study showed that the combination of suspending agents had the most physical stability and pseudoplastic behavior with some degree of thixotropy. Viscosity of suspensions was increased by adding NaCl 0.02%. Presence of PVP is necessary for improving rheological behavior of suspensions by NaCl. This may be related to the cross-linking between the carbonyl group in the PVP segment and Na+ ions. PMID:24109512

    Numerous European clinical trials begun more than 12 years ago have clearly demonstrated flurbiprofen's safety and efficacy as an analgesic, anti-inflammatory, and antipyretic agent. In preclinical studies, flurbiprofen was at least as potent as indomethacin, and approximately 200 times more potent than aspirin. For patients with rheumatoid arthritis, a review of several trials found flurbiprofen often superior to aspirin and naproxen, and equivalent to indomethacin and ibuprofen in efficacy. Acetaminophen appeared no more effective than placebo for patients with rheumatoid arthritis. For patients with ankylosing spondylitis, flurbiprofen was also shown to be equivalent or superior to indomethacin and phenylbutazone. For patients with osteoarthritis of the peripheral joints, spine, hip, and knee, flurbiprofen was again found equal to ibuprofen, diclofenac, indomethacin, and naproxen. Side effects with flurbiprofen were few and predominantly related to the gastrointestinal tract.

    Steven Johnson Syndrome and Toxic Epidermal Necrolysis are rare but severe form of hypersensitivity inflammatory reactions to multiple offending agents including drugs. Acetaminophen is extensively used due to its analgesic and anti-pyretic properties. It is rendered to be relatively safe, with hepatotoxicity considered to be the major adverse effect. However, very few cases of Steven Johnson Syndrome and Toxic Epidermal Necrolysis have been reported with acetaminophen usage in the past. We present the case of a 40 years old lady who developed an overlap of the two condition after taking several doses of acetaminophen for fever. She presented with widespread maculopapular rash, stinging in the eyes, oral mucosal ulcerations and high grade fever. She was successfully treated with corticosteroid therapy along with the supportive treatment. This case addresses the fact, that severe hypersensitivity reactions can occur with acetaminophen which can be potentially life threatening.

    A cluster of infant deaths due to severe metabolic acidosis following immunization was reported in a prosperous farming village in Egypt. Fears that more deaths might occur, and of a deleterious effect on national immunization programs prompted an urgent investigation by national and international partners. The deaths, and other previously unrecognized illness following immunization, were associated with excessive topical application of methanol. Methanol was employed as an anti-pyretic and anti-inflammatory agent following injections. Fear of adverse reactions to vaccine had encouraged increasing use of methanol for these purposes. Local physicians and nurses were unaware of the toxicity of methanol and did not consider it in the differential diagnosis, and thus did not offer appropriate life-saving therapy. The interaction of traditional practices and modern medical interventions can have clinically important consequences, and should be considered when programs are introduced and as they are monitored.

    Full Text Available Laura J Hunter, David M Wood, Paul I DarganClinical Toxicology, Guy’s and St Thomas’ NHS Foundation Trust, London, UKAbstract: The nonsteroidal anti-inflammatory drugs (NSAIDs are widely used for their analgesic, anti-inflammatory and antipyretic actions. They are commonly taken in overdose in many areas of the world. The majority of patients with acute NSAID overdose will remain asymptomatic or develop minor self-limiting gastrointestinal symptoms. However, serious clinical sequelae have been reported in patients with acute NSAID overdose and these include convulsions, metabolic acidosis, coma and acute renal failure. There appear to be some differences between the NSAIDs in terms of the relative risk of these complications; in particular mefenamic acid is most commonly associated with convulsions. The management of these serious clinical features is largely supportive and there are no specific antidotes for acute NSAID toxicity.Keywords: nonsteroidal anti-inflammatory drugs (NSAID, ibuprofen, toxicity, poisoning, overdose, management

    Severe acute malnutrition (SAM) is associated with increased severity of common infectious diseases, and death amongst children with SAM is almost always as a result of infection. The diagnosis and management of infection are often different in malnourished versus well-nourished children. The objectives of this brief are to outline the evidence underpinning important practical questions relating to the management of infectious diseases in children with SAM and to highlight research gaps. Overall, the evidence base for many aspects covered in this brief is very poor. The brief addresses antimicrobials; antipyretics; tuberculosis; HIV; malaria; pneumonia; diarrhoea; sepsis; measles; urinary tract infection; nosocomial Infections; soil transmitted helminths; skin infections and pharmacology in the context of SAM. The brief is structured into sets of clinical questions, which we hope will maximise the relevance to contemporary practice. PMID:25475887

    Laupland, Kevin B

    2009-07-01

    Fever, commonly defined by a temperature of >or=38.3 degrees C (101 degrees F), occurs in approximately one half of patients admitted to intensive care units. Fever may be attributed to both infectious and noninfectious causes, and its development in critically ill adult medical patients is associated with an increased risk for death. Although it is widespread and clinically accepted practice to therapeutically lower temperature in patients with hyperthermic syndromes, patients with marked hyperpyrexia, and selected populations such as those with neurologic impairment, it is controversial whether most medical patients with moderate degrees of fever should be treated with antipyretic or direct cooling therapies. Although treatment of fever may improve patient comfort and reduce metabolic demand, fever is a normal adaptive response to infection and its suppression is potentially harmful. Clinical trials specifically comparing fever management strategies in neurologically intact critically ill medical patients are needed.

    2012-12-01

    Full Text Available Intravenous (IV Paracetamol is an excellent post operative analgesic and antipyretic in children. Efficacy and tolerability of IV Propacetamol have been established in pediatric practice. It is believed that paracetamol works by inhibiting cyclooxygenase-2 (COX-2 enzymes. Studies bring to light that therapeutic doses of IV acetaminophen are effective and tolerable in children with least chances of hepatotoxicity. However, overdose toxicity has been reported in children and drug induced hypotension in febrile critically ill patients. Therapeutic doses according to body weight of neonates and children can be administered in hospital settings. Special education of health care staff regarding precise dose and solution is necessary to assess the role of IV paracetamol preparation in pediatric practice.

    Full Text Available Petiveria alliacea (Phytolaccaceae is a bush widely distributed in South America including Brazil, where it is popularly known as "guiné", pipi", "tipi" or "erva-de-tipi". Brazilian folk medicine attributes to the hot water infusion of its roots or leaves the following pharmacologicalproperties: antipyretic, antispasmodic, abortifacient, antirrheumatic, diuretic, analgesic and sedative. The present study has evaluated the alleged effects of P. alliacea on central nervous system (CNS, particularly, the sedative and analgesic properties of root crude aqueous extract of this plant in mice and rats. This extract showed an antinociceptive effect in acetic acid - acetylcholine - and hypertonic saline - induced abdominal constrictions, but not in hot-plate and tail flick tests P. alliacea did not produce any CNS depressor effect. Thus its antinociceptive action in animals can be responsible by its poplar use as an analgesic.

    Petiveria alliacea (Phytolaccaceae) is a bush widely distributed in South America including Brazil, where it is popularly known as "guiné", "pipi", "tipi" or "erva-de-tipi". Brazilian folk medicine attributes to the hot water infusion of its roots or leaves the following pharmacological properties: antipyretic, antispasmodic, abortifacient, antirrheumatic, diuretic, analgesic and sedative. The present study has evaluated the alleged effects of P. alliacea on central nervous system (CNS), particularly, the sedative and analgesic properties of root crude aqueous extract of this plant in mice and rats. This extract showed an antinociceptive effect in acetic acid--acetylcholine--and hypertonic saline--induced abdominal constrictions, but not in hot-plate and tail flick tests. P. alliacea did not produce any CNS depressor effect. Thus its antinociceptive action in animals can be responsible by its popular use as an analgesic.

    Nonsteroidal anti-inflammatory (NSAI) drugs are the most commonly used group of drugs today. Increase in the use of standard NSAI for treating pain and inflammation was restricted by the fact that these drugs were proven to possibly cause gastrointestinal and renal toxicity. Meloxicam is a NSAI that has anti-inflammatory, analgesic, and antipyretic effects. This study aims to investigate the effects of meloxicam on stomach, kidney, and liver of rats under light microscopy level. Based on the light microscopic observations, mononuclear cell infiltration and pseudolobular formation was established in liver samples of animals in the experimental group. Metaplasia in surface and glandular epithelia and atrophy were observed in stomach samples. Glomerular stasis-related hypertrophy and focal interstitial nephritis were found in kidneys. It was concluded in this study that meloxicam might cause hepatotoxicity, nephrotoxicity, and gastric metaplasia in rats at a used dose and duration. © The Author(s) 2014.

    Eurycoma longifolia Jack is an herbal medicinal plant of South-East Asian origin, popularly recognized as 'Tongkat Ali.' The plant parts have been traditionally used for its antimalarial, aphrodisiac, anti-diabetic, antimicrobial and anti-pyretic activities, which have also been proved scientifically. The plant parts are rich in various bioactive compounds (like eurycomaoside, eurycolactone, eurycomalactone, eurycomanone, and pasakbumin-B) among which the alkaloids and quassinoids form a major portion. Even though toxicity and safety evaluation studies have been pursued, still a major gap exists in providing scientific base for commercial utilization and clearance of the Tongkat Ali products with regard to consumer's safety. The present review aims at reviewing the research works undertaken till date, on this plant in order to provide sufficient baseline information for future works and for commercial exploitation.

    A novel pregabalin derivative named as pregsal ((S,E)-3-(((2-hydroxybenzylidene)amino)methyl)-5-methylhexanoic acid) was synthesized by a simple imination reaction between pregabalin and salicylaldehyde and was evaluated in the in vivo testing paradigms. The compound was characterized by UV, IR, 1 H, 13 C NMR, HR ESI-MS, and elemental analysis. It was screened (30, 50, 75, and 100 mg/kg) for antinociceptive, anti-inflammatory, and antipyretic activities in relation to pregabalin. The synthesized compound significantly attenuated the tonic acetic acid-induced nociceptive pain (30 mg/kg (P pain, inflammation, and pyrexia relieving propensities and therefore may serve as a potential drug candidate for the therapeutic management of chronic pain conditions. © 2017 WILEY-VCH Verlag GmbH & Co.

    We report novel pharmaceutical cocrystal of a popular antipyretic drug paracetamol (PCA) with coformer 5-nitroisophhthalic acid (5NIP) to improve its tabletability. The cocrystal (PCA-5NIP at molar ratio of 1:1) was synthesized by solvent evaporation technique using methanol as solvent. The physicochemical properties of cocrystal were characterized by powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC), thermogravimetry analysis (TGA), fourier transform infrared spectroscopy (FTIR), hot stage polarized microscopy (HSPM) and scanning electron microscopy (SEM). Stability of the cocrystal was assessed by storing them at 40°C/75% RH for one month. Compared to PCA, the cocrystal displayed superior tableting performance. PCA-5NIP cocrystal showed a similar dissolution profile as compared to PCA and exhibited good stability. This study showed the utility of PCA-5NIP cocrystal for improving mechanical properties of PCA. Copyright © 2015 Elsevier B.V. All rights reserved.

    Ficus racemosa is an important medicinal plant, found in India, Australia, and Southeast Asia. It is popularly known as 'gular.' It reduces blood glucose concentration due to the presence of β-sitosterol. Many active constituents that have been isolated from various parts of this plant possess useful pharmacological activities. The literature survey proposed that it has multiple pharmacological actions that include antidiabetic, antioxidant, antidiarrhoeal, anti-inflammatory, antipyretic, antifungal, antibacterial, hypolipidemic, antifilarial, and hepatoprotection. This review article elaborately describes the traditional uses, phytochemistry, pharmacology, and toxicology of this plant. We also provide useful structures of the secondary metabolites along with their nuclear magnetic resonance (NMR) data. Some clinical trial data have also been provided in this review. This review would assist researchers to gather scientific information in future.

    After more than a century, aspirin remains one of the most commonly used drugs in western medicine. Although mainly used for its anti-thrombotic, anti-pyretic, and analgesic properties, a multitude of clinical studies have provided convincing evidence that regular, low-dose aspirin use dramatically lowers the risk of cancer. These observations coincide with recent studies showing a functional relationship between platelets and tumors, suggesting that aspirin's chemopreventive properties may result, in part, from direct modulation of platelet biology and biochemistry. Here, we present a review of the biochemistry and pharmacology of aspirin with particular emphasis on its cyclooxygenase-dependent and cyclooxygenase-independent effects in platelets. We also correlate the results of proteomic-based studies of aspirin acetylation in eukaryotic cells with recent developments in platelet proteomics to identify non-cyclooxygenase targets of aspirin-mediated acetylation in platelets that may play a role in its chemopreventive mechanism.

    Full Text Available We present the case of a 7-year-old boy, who received acetaminophen for the treatment of hyperpyrexia, due to an infection of the superior airways. 13 mg/kg (260 mg of acetaminophen was administered orally before bedtime, and together with the expected antipyretic effect, the boy experienced sleep disruption and proprioceptive delirium. The symptoms disappeared within one hour. In the following six months, acetaminophen was administered again twice, and the reaction reappeared with similar features. Potential alternative explanations were excluded, and analysis with the Naranjo algorithm indicated a “probable” relationship between acetaminophen and this adverse reaction. We discuss the potential mechanisms involved, comprising imbalances in prostaglandin levels, alterations of dopamine, and cannabinoid and serotonin signalings.

    Ibuprofen, a propionic acid derivative, is a non-steroidal anti-inflammatory drug. The oral formulation is widely used in paediatric practice and after paracetamol it is one of the most common drugs prescribed for children in hospital. The treatment of fever with antipyretics such as ibuprofen is controversial as fever is the normal response of the body to infection and unless the child becomes distressed or symptomatic, fever alone should not be routinely treated. Combined treatment with paracetamol and ibuprofen is commonly undertaken but almost certainly is not helpful. This article aims to describe the indications and mode of action of the drug, outline its pharmacokinetics and highlight the important key messages regarding its use in clinical practice.

    Rheum ribes L. is a plant native to China, Iran, Turkey, India, and a few other countries. Antidiarrheal activity is considered to be one of its important properties according to various systems of traditional medicine. An increasing rate of bacterial resistance to antibiotics has led to treatment failure in some cases of shigellosis in children, and underlines a need for safe, efficient and valid options. The purpose of this study is to evaluate the efficacy of R. ribes syrup as a complementary medicine for treatment of shigellosis in children. This randomized, double-blind, placebo-controlled trial started with a group of 150 children aged between 12-72 months with suspected Shigella dysentery. R. ribes syrup or placebo syrup was administered to the intervention and control groups, respectively for 5 days. In addition, the standard antibiotic treatment (ceftriaxone for the first 3 days and cefixime syrup for 2 further days) was administered to both groups. Body temperature, abdominal pain, need for antipyretics, defecation frequency, stool volume and consistency and microscopic stool examination were recorded as outcome measures. Any observed adverse effects were also recorded. Mean duration of fever and diarrhea in the R. ribes group was significantly lower than that in the placebo group (P = 0.016 and 0.001, respectively). In addition, patients in the R. ribes group showed shorter duration of need for antipyretics and shorter duration of abdominal pain (P = 0.012 and 0.001, respectively). However, there were no significant differences between the two groups regarding the microscopic stool analyses. Furthermore, no adverse effect was reported. R. ribes syrup can be recommended as a complementary treatment for children with Shigella dysentery. Iranian Registry of Clinical Trial: IRCT2014070518356N1.

    A variety of herbal plants species has been used in traditional medicine. Most of these plants contained several potent bio-active ingredients and nutrients that could give potential positive effects to the health such as antioxidant and antipyretic. Hibiscus rosa sinensis, commonly known as Bunga raya, have similar concoction characteristic to tea which contain antioxidants that help to control cholesterol. In addition, mucilage that was found in the leaves could helps to reduce extreme body heat during fever (which potentially acts as an antipyretic). Therefore, this preliminary study on the fresh and dried H. rosa sinensis leaves was carried out to analyze and identify the nutrients content, anti-oxidants and inorganic material. Total phenolic content (TPC) method was used for both fresh and dried leaves prior to the antioxidant activities of DPPH free radicals scavenging and ferric ion reducing antioxidant power (FRAP) as to confirm the existence of antioxidant constituents. Meanwhile, the composition of heavy metals was studied using inductively coupled plasma mass spectrometry (ICP-MS). The proximate analysis of the fresh leaves showed the presence of moisture content (9.03 %), protein (10.44 %), fat (6.43 %), crude fiber (11.55 %), ash (11.22 %) and carbohydrate (51.33 %). Meanwhile, the inorganic contents are as follows: cadmium (Cd), chromium (Cr), arsenic (As), nickel (Ni), lead (Pb), iron (Fe) and zinc (Zn). Furthermore, the antioxidant activities of FRAP and DPPH showed that dried leaves of H. rosa sinensis was higher than the fresh leaves (p < 0.05) irrespective of any solvent used. The positive correlation between TPC and two other antioxidant activities of DPPH and FRAP (p < 0.05) indicates the presence of antioxidant components in the acetone and water extracts. Therefore, the high availability of essential nutritional component, anti-oxidants and low concentration of hazardous inorganic matter in H. rosa sinensis leaves enable it to be used as one

    In the care of feverish children, symptomatic management is pivotal. Thus, the Italian Pediatric Society has recently published guidelines on fever management in children. Our aim was to investigate whether pediatric hospitalists, community pediatricians and pediatric residents differ in their every-day clinical practice with respect to symptomatic management of feverish children. 79 out of 118 physicians involved in pediatric care in an area of Northern Lombardy (Italy) filled in a modified version of the questionnaire derived from the Swiss national survey on symptomatic fever management. Pediatric hospitalists (N = 29), community pediatricians (N = 30) and pediatric residents (N = 20) did not differ with respect to temperature threshold for symptomatic fever treatment, role of general appearance in modulating the threshold for fever management, first choice antipyretic drug, frequency of ibuprofen prescription, prescription of physical antipyresis, influence of exaggerated fear of fever on its management and potential to reassure families about this fear.On the other side, some significant differences were found. Pediatric residents more frequently lower the treatment threshold in children with a past history of febrile seizures (P < 0.001) and prescribe an aggressive treatment for fever not responding to the first antipyretic drug (P < 0.01) than their more experienced colleagues. Community pediatricians represent the unique investigated group using homeopathic remedies, both in the acute setting (P < 0.001) as well as a prophylaxis (P < 0.0001). Finally, paediatric residents less often (P < 0.05) stated to encounter exaggerated fear of fever among parents than their more experienced colleagues. The present explorative inquiry globally shows limited discordance among pediatric residents, community pediatricians and pediatric hospitalists with respect to symptomatic fever management.

    To investigate whether (1) resting body temperature is elevated in patients with relapsing-remitting multiple sclerosis (RRMS) relative to healthy individuals and patients with secondary progressive multiple sclerosis (SPMS), and (2) warmer body temperature is linked to worse fatigue in patients with RRMS. Cross-sectional study. Climate-controlled laboratory (∼22°C) within a nonprofit medical rehabilitation research center. Patients with RRMS (n=50), matched healthy controls (n=40), and patients with SPMS (n=22). Not applicable. Body temperature was measured with an aural infrared thermometer (normative body temperature for this thermometer, 36.75°C), and differences were compared across patients with RRMS and SPMS and healthy persons. Patients with RRMS completed measures of general fatigue (Fatigue Severity Scale [FSS]), as well as physical and cognitive fatigue (Modified Fatigue Impact Scale [MFIS]). There was a large effect of group (Pphysical fatigue (physical fatigue subscale of the MFIS; rp=.318, P=.026), but not cognitive fatigue (cognitive fatigue subscale of the MIFS; rp=-.017, P=.909). These are the first-ever demonstrations that body temperature is elevated endogenously in patients with RRMS and linked to worse fatigue. We discuss these findings in the context of failed treatments for fatigue in RRMS, including several failed randomized controlled trials (RCTs) of stimulants (modafinil). In contrast, our findings may help explain how RCTs of cooling garments and antipyretics (aspirin) have effectively reduced MS fatigue, and encourage further research on cooling/antipyretic treatments of fatigue in RRMS.

    Acetaminophen (APAP, paracetamol) mechanism for analgesic and antipyretic outcomes has been largely addressed, but APAP action on cognitive function has not been studied in humans. Animal studies have suggested an improved cognitive performance but the link with analgesic and antipyretic modes of action is incomplete. This study aims at exploring cognitive tests in healthy volunteers in the context of antinociception and temperature regulation. A double-blind randomized controlled study (NCT01390467) was carried out from May 30, 2011 to July 12, 2011. Forty healthy volunteers were included and analyzed. Nociceptive thresholds, core temperature (body temperature), and a battery of cognitive tests were recorded before and after oral APAP (2 g) or placebo: Information sampling task for predecisional processing, Stockings of Cambridge for spatial memory, reaction time, delayed matching of sample, and pattern recognition memory tests. Analysis of variance for repeated measures adapted to crossover design was performed and a two-tailed type I error was fixed at 5%. APAP improved information sampling task (diminution of the number of errors, latency to open boxes, and increased number of opened boxes; all P memory initial thinking time were decreased ( P =0.04). All other tests were not modified by APAP. APAP had an antinociceptive effect ( P body temperature did not change. This study shows for the first time that APAP sharpens decision making and planning strategy in healthy volunteers and that cognitive performance and antinociception are independent of APAP effect on thermogenesis. We suggest that cognitive performance mirrors the analgesic rather than thermic cascade of events, with possibly a central role for serotonergic and cannabinoid systems that need to be explored further in the context of pain and cognition.

    World Health Organization has defined self-medication as the selection and use of medications (including herbal and traditional product) by individuals to treat self-recognized illnesses or symptoms. The prevalence of self-medication is reported to be higher among female students. To investigate the awareness and self-medication practices among female students of higher education institutions in Malaysia. A descriptive, cross-sectional study was conducted in four higher education institutes of Selangor, Malaysia. Convenience sampling approach was used to collect data from a sample 475 students. A "pretested" questionnaire was used as a study instrument. A total of 461 questionnaires were returned (response rate 97.05%). The prevalence of self-medication among female students in higher educational institutions was 57.2% (n = 262). The most common source of self-prescribed medicine was a pharmacy or clinics (n = 206; 45%). It was found that antipyretics were the most common medications used without doctor's consultation (n = 212; 89.1%). Analgesics and antipyretics (n = 79; 62.7%) were highly recommended by students to their family and friends. The common reason for self-medication was prior successful experience (n = 102, 81.0%). The majority of respondents (n = 280; 61.1%) reported that they believed over-the-counter medications were as effective as medications prescribed by a doctor. The prevalence of self-medication practice among female students in the sample of the four higher education institutions was moderate. More studies are required to generalize these findings across Malaysia.

    Full Text Available A Kampo medicine, maoto, has been prescribed in an early phase of influenza-like illness and used for a treatment of influenza clinically in Japan these days. However, the efficacy of maoto against the virus infection remains to be elucidated. This study was conducted to evaluate the alleviative effects of maoto against early phase of influenza virus infection and its preliminary mode of actions through immune systems. When maoto (0.9 and 1.6 g/kg/day was orally administered to A/J mice on upper respiratory tract infection of influenza virus A/PR/8/34 from 4 hours to 52 hours postinfection (p.i. significant antipyretic effect was shown in comparison with water-treated control. Administration of maoto (0.8 and 1.3 g/kg/day significantly decreased the virus titers in both nasal (NLF and bronchoalveolar lavage fluids (BALF at 52 hours p.i., and significantly increased the anti-influenza virus IgM, IgA, and IgG1 antibody titers in NLF, BALF, and serum, respectively. Maoto also increased significantly the influenza virus-bound IgG1 and IgM antibody titers in serum and the virus-bound IgM antibody titer in even the BALF of uninfected A/J mice. These results indicate that maoto exerts antipyretic activity in influenza virus-infected mice and virus reducing effect at an early phase of the infection through probably augmentation of the virus-bound natural antibodies.

    Blood temperature is inversely correlated with oxygen-hemoglobin affinity as demonstrated by in-vitro oxyhemoglobin dissociation curve (ODC) experimentation. To evaluate the real-life effect of fever on blood oxygen saturation (SO2) in children. Children treated in the Pediatric Emergency Department at the "Shaare Zedek" Medical Center with a body temperature > 38.50C were included in the study. Children suffering from active lung disease were excluded. The following parameters were collected before and 90 minutes after administering antipyretic therapy: temperature, SO2, respiratory rate and pulse rate. Twenty-two subjects completed the study. The mean decrease in temperature was 2.030C. Following the decrease in body temperature, a rise in SO2 was noted in 17 subjects (77.3%). The mean SO2 before the antipyretic therapy was 96.18%. The mean SO2 after the drug administration was 97.73%. The average rise in SO2 was 1.55 ± 1.79% (p = 0.001). Fever in children is associated with decreased SO2. This decrease is not clinically significant in patients with normal baseline SO2. Calculation reveals that in patients with baseline SO2 close to the steep region of the ODC, the same increase of body temperature will cause a significantly greater decrease in SO2. In patients with a baseline SO2 of 91% at body temperature of 370C, an increase in body temperature to 400C is anticipated to cause a 5% decrease in SO2. This decrease has major potential implications concerning treatment decisions.

    Chemotherapy of cholangiocarcinoma (CCA), a devastating cancer with increasing worldwide incidence and mortality rates, is largely ineffective. The discovery and development of effective chemotherapeutics is urgently needed. The study aimed at evaluating anticancer activities, toxicity, and pharmacological activities of the curcumin compound (CUR), the crude ethanolic extracts of rhizomes of Zingiber officinale Roscoe (Ginger: ZO) and Atractylodes lancea thung. DC (Khod-Kha-Mao: AL), fruits of Piper chaba Hunt. (De-Plee: PC), and Pra-Sa-Prao-Yhai formulation (a mixture of parts of 18 Thai medicinal plants: PPF) were investigated in animal models. Anti-cholangiocarcinoma (anti-CCA) was assessed using CCA-xenograft nude mouse model. The antihypertensive, analgesic, anti-inflammatory, antipyretic, and anti-ulcer activities and effects on motor coordination were investigated using Rota-rod test, CODA tail-cuff system, writhing and hot plate tests, carrageenan-induced paw edema test, brewer's yeast test, and alcohol-induced gastric ulcer test, respectively. Acute and subacute toxicity tests were performed according to the OECD guideline for testing of chemicals with modification. Promising anticancer activity against CCA in nude mouse xenograft model was shown for the ethanolic extract of AL at all oral dose levels (1000, 3000, and 5000 mg/kg body weight) as well as the extracts of ZO, PPF, and CUR compound at the highest dose level (5000, 4000, and 5000 mg/kg body weight, respectively). PC produced no significant anti-CCA activity. Results from acute and subacute toxicity tests both in mice and rats indicate safety profiles of all the test materials in a broad range of dose levels. No significant toxicity except stomach irritation and general CNS depressant signs were observed. Investigation of pharmacological activities of the test materials revealed promising anti-inflammatory (ZO, PPF, and AL), analgesic (CUR and PPF), antipyretic (CUR and AL), antihypertensive (ZO

    Medication errors are widely reported for hospitalised patients, but limited data are available for medication errors that occur in community-based and clinical settings. Epidemiological data from poisons information centres enable characterisation of trends in medication errors occurring across the healthcare spectrum. The objective of this study was to characterise the epidemiology and type of medication errors reported to the National Poisons Information Centre (NPIC) of Ireland. A 3-year prospective study on medication errors reported to the NPIC was conducted from 1 January 2007 to 31 December 2009 inclusive. Data on patient demographics, enquiry source, location, pharmaceutical agent(s), type of medication error, and treatment advice were collated from standardised call report forms. Medication errors were categorised as (i) prescribing error (i.e. physician error), (ii) dispensing error (i.e. pharmacy error), and (iii) administration error involving the wrong medication, the wrong dose, wrong route, or the wrong time. Medication errors were reported for 2348 individuals, representing 9.56% of total enquiries to the NPIC over 3 years. In total, 1220 children and adolescents under 18 years of age and 1128 adults (≥ 18 years old) experienced a medication error. The majority of enquiries were received from healthcare professionals, but members of the public accounted for 31.3% (n = 736) of enquiries. Most medication errors occurred in a domestic setting (n = 2135), but a small number occurred in healthcare facilities: nursing homes (n = 110, 4.68%), hospitals (n = 53, 2.26%), and general practitioner surgeries (n = 32, 1.36%). In children, medication errors with non-prescription pharmaceuticals predominated (n = 722) and anti-pyretics and non-opioid analgesics, anti-bacterials, and cough and cold preparations were the main pharmaceutical classes involved.

    To observe synergistic effects of 999 Ganmaoling (GML) and its Chinese/Western materia medica (CMM and WMM) on pharmacodynamic action and to study underlying mechanisms, their anti-inflammatory, antipyretic effects were compared by assaying the increased capillary permeability induced by glacial acetic acid in mice, ear swelling induced by Xylene in mice, non-specific pleurisy induced by carrageenan in rats, and yeast induced fever in rats. Crystal violet (CV) and microbial activity (XTT) assay were used to evaluate the inhibition of GML and its CMM and WMM on KPN biofilm formation, and scanning electron microscopy (SEM) was applied for observing KPN biofilm morphology changes. The results showed that compared with control group, GML could reduce exudation amount of Evans-Blue and the degree of Ear swelling significantly, and CMM and WMM have no significant effects. The concentration of TNF-α and IL-1β of rat pleural effusion in GML, CMM and WMM group decreased significantly. The concentration of TNF-α, IL-1β and IL-8 in GML group, TNF-α, IL-8 in WMM group and IL-8 in CMM in rats serum decreased significantly. The body temperature in rats decreased significantly in GML and WMM group after 4-8 h of administration. CMM group showed no significant difference in rat body temperature compare with control. Compared with control group, GML (55-13.75 g•L⁻¹) could inhibit KPN biofilm formation and reduce number of viable cells in the KPN biofilm. CMM (45-22.5 g•L⁻¹) and WMM (10 g•L⁻¹) could also inhibit KPN biofilm formation and reduce number of viable cells (P<0.01). Result of SEM also showed that GML (55 g•L⁻¹) and its CMM (45 g•L⁻¹) and WMM (10 g•L⁻¹) could interfere the bacterial arrangement of KPN biofilm and extracellular matrix. GML and its CMM & WMM could inhibit the formation of KPN biofilm, CMM & WMM in GML showed synergism and complementation in inhibit KPN biofilm. Results showed that GML had obvious anti-inflammatory and

For reducing the GI toxicity, the free carboxylic group (–COOH was temporarily masked by esterification with phenolic –OH of natural antioxidants vanillin, thymol, umbelliferone, and sesamol. The in vitro hydrolysis of synthesized prodrugs showed that they were stable in buffer solution at pH 1.2, indicating their stability in the stomach. The synthesized prodrugs undergo significant hydrolysis in 80% human plasma and thus release free flurbiprofen. The minimum reversion was observed at pH 1.2, ­suggesting that prodrugs are less irritating to the stomach than flurbiprofen. The anti-inflammatory, analgesic, antipyretic, and ulcerogenic activities of prodrugs were evaluated. All the synthesized prodrugs significantly (P<0.001 reduced the inflammation against carrageenan and egg albumin-induced paw edema at 4 hours of study. The reduction in the size of the inflamed paw showed that most of the compounds inhibited the later phase of inflammation. The prodrug 2-oxo-2H-chromen-7-yl-2-(2-fluorobiphenyl-4-ylpropanoate (4b showed significant reduction in paw licking with percentage inhibition of 58%. It also exhibited higher analgesic activity, reducing the number of writhes with a percentage of 75%, whereas flurbiprofen showed 69% inhibition.

    INTRODUCTION: Medication errors are widely reported for hospitalised patients, but limited data are available for medication errors that occur in community-based and clinical settings. Epidemiological data from poisons information centres enable characterisation of trends in medication errors occurring across the healthcare spectrum. AIM: The objective of this study was to characterise the epidemiology and type of medication errors reported to the National Poisons Information Centre (NPIC) of Ireland. METHODS: A 3-year prospective study on medication errors reported to the NPIC was conducted from 1 January 2007 to 31 December 2009 inclusive. Data on patient demographics, enquiry source, location, pharmaceutical agent(s), type of medication error, and treatment advice were collated from standardised call report forms. Medication errors were categorised as (i) prescribing error (i.e. physician error), (ii) dispensing error (i.e. pharmacy error), and (iii) administration error involving the wrong medication, the wrong dose, wrong route, or the wrong time. RESULTS: Medication errors were reported for 2348 individuals, representing 9.56% of total enquiries to the NPIC over 3 years. In total, 1220 children and adolescents under 18 years of age and 1128 adults (>\\/= 18 years old) experienced a medication error. The majority of enquiries were received from healthcare professionals, but members of the public accounted for 31.3% (n = 736) of enquiries. Most medication errors occurred in a domestic setting (n = 2135), but a small number occurred in healthcare facilities: nursing homes (n = 110, 4.68%), hospitals (n = 53, 2.26%), and general practitioner surgeries (n = 32, 1.36%).

    Background. There is an urgent need to develop new treatment strategies and drugs for pancreatic cancer that is highly resistant to radio-chemotherapy. Aesculus hippocastanum (the horse chestnut) known in Chinese medicine as a plant with anti-inflammatory, antiedema, antianalgesic, and antipyretic activities. The main active compound of this plant is Escin (C54H84O23). Objective. To evaluate the effect of Escin alone and combined with chemotherapy on pancreatic cancer cell survival and to unravel mechanism(s) of Escin anticancer activity. Methods. Cell survival was measured by XTT colorimetric assay. Synergistic effect of combined therapy was determined by CalcuSyn software. Cell cycle and induction of apoptosis were evaluated by FACS analysis. Expression of NF- κ B-related proteins (p65, I κ Bα, and p-I κ Bα) and cyclin D was evaluated by western blot analysis. Results. Escin decreased the survival of pancreatic cancer cells with IC50 = 10-20 M. Escin combined with gemcitabine showed only additive effect, while its combination with cisplatin resulted in a significant synergistic cytotoxic effect in Panc-1 cells. High concentrations of Escin induced apoptosis and decreased NF- κ B-related proteins and cyclin D expression. Conclusions. Escin decreased pancreatic cancer cell survival, induced apoptosis, and downregulated NF- κ B signaling pathway. Moreover, Escin sensitized pancreatic cancer cells to chemotherapy. Further translational research is required.

    Aesculus hippocastanum (the horse chestnut) seed extract has a wide variety of biochemical and pharmacological effects including anti-inflammatory, antianalgesic, and antipyretic activities. The main active compound of this plant is escin. It is known that several medicinal herbs with anti-inflammatory properties have been found to have a role in the prevention and treatment of cancer. In the present study, the cytotoxic effects of escin in the C6 glioma and A549 cell lines were analyzed by MTT. Apoptotic effects of escin on both cell lines were evaluated by Annexin V binding capacity with flow cytometric analysis. Structural and ultrastructural changes were also evaluated using transmission electron microscopy. The results indicated that escin has potent antiproliferative effects against C6 glioma and A549 cells. These effects are both dose and time dependent. Taken together, escin possesses cell cycle arrest on G0/G1 phase and selective apoptotic activity on A549 cells as indicated by increased Annexin V-binding capacity, bax protein expression, caspase-3 activity and morphological changes obtained from micrographs by transmission electron microscopy.

    Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) of the phenylacetic acid class with anti-inflammatory, analgesic, and antipyretic properties. Contrary to the action of many traditional NSAIDs, diclofenac inhibits cyclooxygenase (COX)-2 enzyme with greater potency than it does COX-1. Similar to other NSAIDs, diclofenac is associated with serious dose-dependent gastrointestinal, cardiovascular, and renal adverse effects. Since its introduction in 1973, a number of different diclofenac-containing drug products have been developed with the goal of improving efficacy, tolerability, and patient convenience. Delayed- and extended-release forms of diclofenac sodium were initially developed with the goal of improving the safety profile of diclofenac and providing convenient, once-daily dosing for the treatment of patients with chronic pain. New drug products consisting of diclofenac potassium salt were associated with faster absorption and rapid onset of pain relief. These include diclofenac potassium immediate-release tablets, diclofenac potassium liquid-filled soft gel capsules, and diclofenac potassium powder for oral solution. The advent of topical formulations of diclofenac enabled local treatment of pain and inflammation while minimizing systemic absorption of diclofenac. SoluMatrix diclofenac, consisting of submicron particles of diclofenac free acid and a proprietary combination of excipients, was developed to provide analgesic efficacy at reduced doses associated with lower systemic absorption. This review illustrates how pharmaceutical technology has been used to modify the pharmacokinetic properties of diclofenac, leading to the creation of novel drug products with improved clinical utility.

    The purpose of this study was to develop a nasal in situ gel system for Radix Bupleuri employing gellan gum as a polymer. Radix Bupleuri in situ gel containing 0.2 mL essential oil extracted from 450 g Radix Bupleuri, proper solubilizing agents and gellan gum (0.5% w/v) was prepared and characterized. The antipyretic effect produced by in situ gel formulation was investigated in fevered rabbits and compared to an intranasal solution. The resulting in situ gel was a clear and light-yellow liquid, with viscosity of 346 mPa x s and caproic acid content of 1.31 +/- 0.01 mg/mL. Intranasal administration of this preparation to fevered rabbits decreased body temperature markedly (1.1 degree C at the doses of oil from 1.5 g Bupleuri/body) and the effect could last for 20-30 h. The results suggest that Radix Bupleuri in situ gel can be greater effective than the solution in the treatment of fever.

    This review reports main progresses in various pediatric issues published in Italian Journal of Pediatrics and in international journals in 2016. New insights in clinical features or complications of several disorders may be useful for our better understanding. They comprise severe asthma, changing features of lupus erythematosus from birth to adolescence, celiac disease, functional gastrointestinal disorders, Moebius syndrome, recurrent pneumonia. Risk factors for congenital heart defects, Kawasaki disease have been widely investigated. New diagnostic tools are available for ascertaining brucellosis, celiac disease and viral infections. The usefulness of aCGH as first-tier test is confirmed in patients with neurodevelopmental disorders. Novel information have been provided on the safety of milk for infants. Recent advances in the treatment of common disorders, including neonatal respiratory distress syndrome, hypo-glycemia in newborns, atopic dermatitis, constipation, cyclic vomiting syndrome, nephrotic syndrome, diabetes mellitus, regurgitation, short stature, secretions in children with cerebral palsy have been reported. Antipyretics treatment has been updated by national guidelines and studies have excluded side effects (e.g. asthma risk during acetaminophen therapy). Vaccinations are a painful event and several options are reported to prevent this pain. Adverse effects due to metabolic abnormalities are reported for second generation antipsychotic drugs.

    Full Text Available Schiff bases and their complexes are versatile compounds synthesized from the condensation of an amino compound with carbonyl compounds and widely used for industrial purposes and also exhibit a broad range of biological activities including antifungal, antibacterial, antimalarial, antiproliferative, anti-inflammatory, antiviral, and antipyretic properties. Many Schiff base complexes show excellent catalytic activity in various reactions and in the presence of moisture. Over the past few years, there have been many reports on their applications in homogeneous and heterogeneous catalysis. The high thermal and moisture stabilities of many Schiff base complexes were useful attributes for their application as catalysts in reactions involving at high temperatures. The activity is usually increased by complexation therefore to understand the properties of both ligands and metal can lead to the synthesis of highly active compounds. The influence of certain metals on the biological activity of these compounds and their intrinsic chemical interest as multidentate ligands has prompted a considerable increase in the study of their coordination behaviour. Development of a new chemotherapeutic Schiff bases and their metal complexes is now attracting the attention of medicinal chemists. This review compiles examples of the most promising applied Schiff bases and their complexes in different areas.

    Full Text Available Several new pyrazolopyrimidine compounds were achieved from aminocyanopyarazole 1. The starting material 1 was initially coupled with orthoester at refluxed with various primary amines, ammonia, hydrazines and hydroxylamine to furnish a series of pyrazolo[3,4-d]pyrimidines. The reaction of imidate 2a-b with hydrazide derivatives led to the formation of pyrazolo[3,4-d][1,2,4]triazolo[4,3-c]pyrimidines. Some of the synthesized compounds 3a and 4c were evaluated for their anti-inflammatory, antipyretic and nociceptive activities. We start by studing the toxicity of these two molecules by measuring the corresponding DL50. The DL50 of 3a and 4c are estimated to 1333.2mg / kg and 1593.5mg / kg respectively. Pharmacological evaluation showed that compounds 3a and 4c at doses (5.5-22.2 mg / Kg, i.p exhibited anti-inflammatory activities compared to Ibuprofen (150 mg / Kg, i.p, used as a refer ence drug. Further, our study showed that the injection of derived pyrazolopyrimidines on hyperthermic animal leads to a decrease in temperature after 1 hours of treatment compared to paracetamol used as reference. In addition, the injection of derived pyrazolopyrimidines at different doses contains a potent nociceptive activity. This effect is dose-dependent compared to aspirin.

    Full Text Available Aspirin (acetylsalicylic acid is a well-known nonsteroidal anti-inflammatory drug (NSAID that has long been used as an anti-pyretic and analgesic drug. Recently, much attention has been paid to the chemopreventive and apoptosis-inducing effects of NSAIDs in cancer cells. These effects have been thought to be primarily attributed to the inhibition of cyclooxygenase activity and prostaglandin synthesis. However, recent studies have demonstrated unequivocally that certain NSAIDs, including aspirin and its metabolite salicylic acid, exert their anti-inflammatory and chemopreventive effects independently of cyclooxygenase activity and prostaglandin synthesis inhibition. It is becoming increasingly evident that two potential common targets of NSAIDs are mitochondria and the Ca2+ signaling pathway. In this review, we provide an overview of the current knowledge regarding the roles of mitochondria and Ca2+ in the apoptosis-inducing effects as well as some side effects of aspirin, salicylates and other NSAIDs, and introducing the emerging role of L-type Ca2+ channels, a new Ca2+ entry pathway in non-excitable cells that is up-regulated in human cancer cells.

    Benjalokawichien (BLW) or Ya-Ha-Rak (HR) is a traditional remedy in the Nationaldrug list of herbal medicinal products AD 2012 of Thailand. For traditional use, BLW is used as antipyretic agent. It also has anti-allergic effect, particularly treating allergic rash. The ethanolic extract of BLW exhibited anti-allergic activity via inhibitory effect against a release ofbeta-hexosaminidase in RBL-2H3 cell line. Pectolinarigenin has been identified as the active compound ofBLW extract. In this study, a reversed-phase high performance liquid chromatography (RP-HPLC) method was developed in order to control quality ofpreparation in three aspects such as chemical fingerprint, quantification and stability of the ethanolic extract. The RP-HPLC was performed with a gradient mobile phase composed of 0.1% ortho phosphoric acid and acetronitrile, and peaks were detected at 331 nm. Based on validation results, this analytical method is precise, accurate and stable for quantitative determination ofpectolinarigenin. The amount ofpectolinarigenin in Benjalokawichien extract determined by this method was 18.50 mg/g ofextract. Therefore, this method could be consideredfor quality control ofBLWextract.

    Gumiganghwal-tang (GT) is a traditional herbal medicine that is widely used for its anti-inflammatory, analgesic, and antipyretic actions. Fermented GT has been reported to inhibit acetylcholinesterase (AChE) activity and to exert a neuroprotective effect. In this study, we investigated the effect of fermented GT against scopolamine-induced memory impairment in mice using the Morris water maze and passive avoidance tests. The results of the Morris water maze test indicated that fermented GT significantly decreased escape latency, as compared with that observed in the scopolamine-treated group. In the prove test, fermented GT attenuated the decreased time spent in the target quadrant observed after scopolamine treatment. The results of the passive avoidance test indicated that the treatment with fermented GT increased latency time when compared with the scopolamine-treated group. Moreover, fermented GT inhibited AChE activity in the hippocampi of the treated mice. These results suggest that fermented GT reduced scopolamine-induced amnesia in mice through AChE inhibition. Therefore, we hypothesize that fermented GT may be a useful therapeutic agent for the prevention or treatment of neurodegenerative diseases.

    In many countries, ibuprofen is available only in oral formulations. The authors aimed to investigate parental satisfaction and possible adverse reactions among children receiving newly marketed ibuprofen suppositories, prior to their arrival at the pharmaceutical points of distribution. Children needing antipyretic medication were recruited from 11 pediatric wards and clinics in Israel. Each patient received ibuprofen suppositories (5-10 mg/kg/dose) after completing a data collection form. After 3 to 7 days of treatment, information regarding parent satisfaction, possible adverse reactions, and concomitant use of drugs was obtained. Overall, 490 children completed the study. Parents' satisfaction was high (4.5 ± 0.47 on a scale of 1-5), and 92.2% reported that they would use the medication in the future. Adverse reactions were reported in 8 patients (1.63%, 95% confidence interval = 1.77-3.25), the most common being diarrhea. Rectal administration of ibuprofen suppositories is well tolerated and overall satisfaction and the repeated expected use were high.

    Full Text Available Hantaviruses are the causative agents of hantavirus pulmonary syndrome in humans in the Americas; The primary reservoirs are in the rodents of the subfamily Sigmodontinae. In South America, cases of hantavirus pulmonary syndrome caused by numerous viral genotypes have been diagnosed. In Colombia, different serological studies have reported the circulation of hantavirus in humans and rodents. These viruses act in an intimate association with a rodent species that serves as a reservoir and have a distribution around the wild rodent, being limited to a specific geographic region. In South America, the first HPS-associated hantavirus was described in 1993 in Brazil and was called Juquitiva and from 1993 to 2012, more than 1400 cases had been identified in Brazil. This syndrome should be suspected in all patients with respiratory distress syndrome of unclear etiology, in areas endemic for the disease, especially if accompanied by fever, marked leukocytosis and thrombocytopenia and bilateral interstitial infiltrates. Hemorrhagic febrile syndrome has not yet been described in the Americas. There are no clinical or laboratory signs that are pathognomonic of hantavirus infection. The treatment is based on adequate hydration, use of antipyretics and anti-inflammatories and patients with signs of severity should establish a more aggressive management. Triage is indispensable, patients with co-morbidities have a higher mortality risk and therefore should be hospitalized. Future research in Colombia should be directed to multidisciplinary studies that include viral isolation, different clinical forms of case presentation, epidemiological differences, risk factors, and taxonomy of viruses and rodents.

    Full Text Available Caesalpinia ferrea Mart. belongs to the family Fabaceae. Known as pau-ferro and jucá, it is used in folk medicine to treat diabetes, as antipyretic and antirheumatic. This study aimed to evaluate the anti-inflammatory and antinociceptive activities of the ethanol extract of the fruits of C. ferrea (EECf. In the evaluation of anti-inflammatory activity, EECf (50 mg/kg produced significantly inhibition of ear edema by 66.6% compared to control. Indomethacin (10 mg/kg showed inhibition of 83.9% compared to control. EECf (50 mg/kg inhibited of vascular permeability induced by acetic acid and was also able to reduce of cell migration to the peritoneal cavity induced by thioglycolate. In the writhing test induced by acid acetic, EECf (12.5, 25 and 50 mg/kg significantly reduced the number of contortions by 24.9, 46.9 and 74.2%, respectively. In the formalin test, EECf presented effects only in the second phase. The results provided experimental evidence for the effectiveness of the traditional use of C. ferrea in treating various diseases associated with inflammation and pain.

    Cyclooxygenase (COX), a prostaglandin-endoperoxide synthase (PTGS), catalyzes the formation of prostaglandins from arachidonic acid. Prostaglandins are lipid signaling mediators that play a central role in a broad range of diverse physiological and pathophysiological processes, including inflammation, reproduction, nocioception, and gastrointestinal protection. Inhibition of cyclooxygenase activity is the mechanism by which nonsteroidal antiinflammatory drugs (NSAIDS) exert their analgesic, antipyretic, antiinflammatory, and antithrombotic effects. COX is currently believed to exist in three isoforms. In this review, we provide a concise state-of-the-art description of the role of COX in pharmacology and toxicology of skin including its involvement in normal physiology, cutaneous inflammation, nociception, wound healing, and tumorigenesis. COX-dependent pathways influence keratinocyte differentiation, hair follicle development, and hair growth. The critical role of COX-2 in pathophysiology of skin is also addressed. COX-2 mediates inflammatory processes in skin, including inflammatory hyperalgesia and nociception, and administration of specific COX-2 inhibitors reduces edema, vascular permeability, and other markers of cutaneous inflammation. A number of studies in animal models and in humans show that COX-2 inhibitors possess cancer chemopreventive properties. Selective COX-2 inhibitors have a more favorable side-effect profile. Topical formulations of COX-2 inhibitors are being developed as a novel pharmacologic approach for the treatment of COX-2 mediated skin diseases

    This study investigated the effects of nanosuspension and inclusion complex techniques on in vitro trypsin inhibitory activity of naproxen—a member of the propionic acid derivatives, which are a group of antipyretic, analgesic, and non-steroidal anti-inflammatory drugs. Nanosuspension and inclusion complex techniques were used to increase the solubility and anti-inflammatory efficacy of naproxen. The evaporative precipitation into aqueous solution (EPAS) technique and the kneading methods were used to prepare the nanosuspension and inclusion complex of naproxen, respectively. We also used an in vitro protease inhibitory assay to investigate the anti-inflammatory effect of modified naproxen formulations. Physiochemical properties of modified naproxen formulations were analyzed using UV, IR spectra, and solubility studies. Beta-cyclodextrin inclusion complex of naproxen was found to have a lower percentage of antitryptic activity than a pure nanosuspension of naproxen did. In conclusion, nanosuspension of naproxen has a greater anti-inflammatory effect than the other two tested formulations. This is because the nanosuspension formulation reduces the particle size of naproxen. Based on these results, the antitryptic activity of naproxen nanosuspension was noteworthy; therefore, this formulation can be used for the management of inflammatory disorders. (author)

    To identify consumer information needs about paracetamol, the most commonly used analgesic and antipyretic worldwide. Retrospective analysis of medicines questions from the public. Australian consumer medicines call centre. Callers to National Prescribing Service Medicines Line between September 2002 and June 2010 (n=123 217). Enquiry profile: demographics, enquiry type and concurrent medicines included in paracetamol calls; question themes derived from subset of call narratives. Paracetamol comprised part of the enquiry in 5.2% of calls (n=6367). The caller age distribution for paracetamol calls was skewed towards a younger cohort, with 45.2% made by those aged 25-44 vs 37.5% in 'rest of calls'. Significantly more paracetamol-related calls were made for a child (23.7%) compared with 'rest of calls' (12.7%, pConsumers have many concerns about the use of paracetamol that may be under-recognised by healthcare providers, with the nature of enquiries differing across life stages. These concerns are not adequately addressed by available consumer information. Improving access to targeted information about paracetamol would promote the safe and effective use of this common medicine. Published by the BMJ Publishing Group Limited.

    The objective of this study is to find out the prevalence and determinants of self-medication among college students in Baghdad, Iraq. A cross-sectional survey was conducted in Al-Mustansiriyah and Al-Nahrain universities, Baghdad, from January to April 2015. A multistage random sampling technique was adopted to collect data from 1435 college students using a questionnaire form. The mean age of the joining students was 19.8 years. Females form 53% of the sample. Self-medications use was prevalent among 92.4% of students. Antipyretics and antibiotics were the most used medicines. Self-medication was higher among urban residents (OR= 7.99, P self-medication more than others (OR= 2.501, P = 0.037). Students at health-related colleges showed greater resilience to self-medication (OR=0.455, P = 0.001). Despite free access to healthcare institutions, nine out of ten college students from Baghdad universities have practiced self-medication. Education of students about the safe use of medications and supervision of pharmacies are effective ways to control this malpractice.

    Full Text Available Acetaminophen is used as an analgesic and antipyretic agent. The aim of the study was evaluation of the effect of different polymers on rheological behavior of acetaminophen suspension. In order to achieve controlled flocculation, sodium chloride was added. Then structural vehicles such as carboxymethyl cellulose (CMC, polyvinyl pyrrolidone (PVP, tragacanth, and magnesium aluminum silicate (Veegum were evaluated individually and in combination. Physical stability parameters such as sedimentation volume (F, redispersibility (n, and growth of crystals of the suspensions were determined. Also, the rheological properties of formulations were studied. The results of this study showed that the combination of suspending agents had the most physical stability and pseudoplastic behavior with some degree of thixotropy. Viscosity of suspensions was increased by adding NaCl 0.02%. Presence of PVP is necessary for improving rheological behavior of suspensions by NaCl. This may be related to the cross-linking between the carbonyl group in the PVP segment and Na+ ions.

    Thirty million people worldwide consume each day nonsteroidal anti-inflammatory drugs (NSAIDs), a heterogeneous group of pharmaceuticals used for its analgesic, antipyretic, and anti-inflammatory properties. Recent studies report high NSAID concentrations in wastewater treatment plant effluents, in surface, ground, and drinking water, and in sediments. NSAIDs are also known to induce toxicity on aquatic organisms. However, toxicity in natural ecosystems is not usually the result of exposure to a single substance but to a mixture of toxic agents, yet only a few studies have evaluated the toxicity of mixtures. The aim of this study was to evaluate the toxicity induced by diclofenac (DCF), ibuprofen (IBP), and their mixture on a species of commercial interest, the common carp Cyprinus carpio. The median lethal concentration of IBP and DCF was determined, and oxidative stress was evaluated using the following biomarkers: lipid peroxidation and activity of the antioxidant enzymes superoxide dismutase, catalase and glutathione peroxidase. Cyto-genotoxicity was evaluated by micronucleus test, comet assay, and the specific activity of caspase-3. Results show that DCF, IBP, and a mixture of these pharmaceuticals induced free radical production, oxidative stress and cyto-genotoxicity in tissues of C. carpio. However, a greater effect was elicited by the mixture than by either pharmaceutical alone in some biomarkers evaluated, particularly in gill. © 2016 Wiley Periodicals, Inc.

    Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) with analgesic and anti-pyretic properties. This compound is therefore used to treat pain, inflammatory disorders, and dysmenorrhea. Due to its multimodal mechanism of action and ability to penetrate placenta, diclofenac is known to have undesirable side effects including teratogenicity. However, limited data exist on its teratogenicity, and a detailed investigation regarding harmful effects of this drug during embryogenesis is warranted. Here, we analyzed the developmental toxic effects of diclofenac using Xenopus embryos according to the Frog Embryo Teratogenesis Assay-Xenopus (FETAX) protocol. Diclofenac treatment exerted a teratogenic effect on Xenopus embryos with a teratogenic index (TI) value of 2.64 TI; if this value is higher than 1.2, the cut-off value indicative of toxicity. In particular, mortality of embryos treated with diclofenac increased in a concentration-dependent manner and a broad spectrum of malformations such as shortening and kinking of the axis, abdominal bulging, and prominent blister formation, was observed. The shape and length of internal organs also differed compared to the control group embryos and show developmental retardation on histological label. However, the expression of major tissue-specific markers did not change when analyzed by reverse transcription-polymerase chain reaction (RT-PCR). In conclusion, diclofenac treatment can promote teratogenicity that results in morphological anomalies, but not disrupt the developmental tissue arrangement during Xenopus embryogenesis.

    Diclofenac is the most commonly used phenylacetic acid derivative non-steroidal anti-inflammatory drug (NSAID) that demonstrates significant analgesic, antipyretic, and anti-inflammatory effects. Several epidemiological studies have demonstrated anti-proliferative activity of NSAIDs and examined their apoptotic induction effects in different cancer cell lines. However, the precise molecular mechanisms by which these pharmacological agents induce apoptosis and exert anti-carcinogenic properties are not well known. Here, we have observed that diclofenac treatment induces proteasome malfunction and promotes accumulation of different critical proteasome substrates, including few pro-apoptotic proteins in cells. Exposure of diclofenac consequently elevates aggregation of various ubiquitylated misfolded proteins. Finally, we have shown that diclofenac treatment promotes apoptosis in cells, which could be because of mitochondrial membrane depolarization and cytochrome c release into cytosol. This study suggests possible beneficial insights of NSAIDs-induced apoptosis that may improve our existing knowledge in anti-proliferative interspecific strategies development. J. Cell.

    Since being introduced globally as aspirin in 1899, acetylsalicylic acid has been widely used as an analgesic, anti-inflammation, anti-pyretic, and anti-thrombotic drug for years. Aspirin had been reported to down-regulate surface expression of CD40, CD80, CD86, and MHCII in myeloid dendritic cells (DC), which played essential roles in regulating the immune system. We hypothesized that the down-regulation of these surface membrane proteins is partly due to the ability of aspirin in regulating trafficking/sorting of endocytosed surface membrane proteins. By using an established epidermoid carcinoma cell line (A-431), which overexpresses the epidermal growth factor receptor (EGFR) and transferrin receptor (TfnR), we show that aspirin (1) reduces cell surface expression of EGFR and (2) accumulates endocytosed-EGFR and -TfnR in the early/sorting endosome (ESE). Further elucidation of the mechanism suggests that aspirin enhances recruitment of SNX3 and SNX5 to membranes and consistently, both SNX3 and SNX5 play essential roles in the aspirin-mediated accumulation of endocytosed-TfnR at the ESE. This study sheds light on how aspirin may down-regulate surface expression of EGFR by inhibiting/delaying the exit of endocytosed-EGFR from the ESE and recycling of endocytosed-EGFR back to the cell surface.

    Acetaminophen (APAP) is a widely prescribed analgesic and antipyretic drug. In the present work, we studied the effects of glutamine (Gln) in an in vivo model of APAP-induced nephrotoxicity in male Wistar rats. Renal function, histological characteristics, and Na + ,K + -ATPase cortical abundance and distribution were analyzed. The appearance of HSP70 and actin in urine was also evaluated. Myeloperoxidase (MPO) activity in cortical tissue was measured as an index of the inflammatory response. Gln administration 30 min before APAP protected from the renal functional and histological damage promoted by APAP. Rats that received the dual treatment Gln and APAP (Gln/APAP) showed the same level of Na + ,K + -ATPase cortical induction as APAP-treated animals, but the enzyme maintained its normal basolateral localization. HSP70 abundance was increased up to the same level in the Gln, APAP, and Gln/APAP groups. Urinary HSP70 and actin were detected only in the APAP-treated animals, reinforcing the protection of renal tubular integrity afforded by the Gln pretreatment. Gln pretreatment also protected from the increment in MPO activity promoted by APAP. Our results support the idea that Gln pretreatment could be a therapeutic option to prevent APAP-induced renal injury.

    Full Text Available Paracetamol is one of the most commonly used analgesics and antipyretics available without limits as preparations of the OTC group (over the counter drugs. Overdose and poisoning with this drug always brings about the risk of acute hepatic failure. The objective of the study was a retrospective evaluation of patients hospitalized in the Paediatric Clinic during the period 2004–2012 due to poisoning with paracetamol.The analysis covered 44 patients hospitalized in the Paediatric Clinic during 2004–2012 due to poisoning with paracetamol. Patients were divided into three groups: intentional poisonings, accidental poisonings, and drug overdose.During the period of the study, 44 patients aged 2.1–17.1, poisoned with paracetamol, were hospitalized. Among these patients there were 30 (68.2% cases of intentional poisonings, 10 (22.7% of accidental poisonings, and only 4 patients (9.1% were children hospitalized after a paracetamol overdose. The majority of patients in all groups were females (93.3%.Paracetamol intoxication may occur after exceeding a single allowable dose, in the case of intentional poisoning, more rarely after exceeding the daily dose, in the case of intense pain complaints, or in the treatment of persistent fever.Based on the analysis performed, an increase was observed in the frequency of poisoning with paracetamol, especially intentional poisoning. Unlimited access to paracetamol as an OTC drug should be reconsidered.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are worldwide used drugs for analgesic, antipyretic, and anti-inflammatory therapeutics. However, NSAIDs often cause several serious liver injuries, such as drug-induced liver injury (DILI), and the molecular mechanisms of DILI have not been clearly elucidated. In this study, we developed a systems pharmacology approach to explore the mechanism-of-action of NSAIDs. We found that the Farnesoid X Receptor (FXR) antagonism of NSAIDs is a potential molecular mechanism of DILI through systematic network analysis and in vitro assays. Specially, the quantitative real-time PCR assay reveals that indomethacin and ibuprofen regulate FXR downstream target gene expression in HepG2 cells. Furthermore, the western blot shows that FXR antagonism by indomethacin induces the phosphorylation of STAT3 (signal transducer and activator of transcription 3), promotes the activation of caspase9, and finally causes DILI. In summary, our systems pharmacology approach provided novel insights into molecular mechanisms of DILI for NSAIDs, which may propel the ways toward the design of novel anti-inflammatory pharmacotherapeutics.

    Cyclooxygenases (COX) are key enzymes in the prostaglandin synthesis. There are two isoforms of the COX enzyme, COX-1 and COX-2. COX-2 expression is associated with carcinogenesis in variety of cancers and to render cells resistant to apoptotic stimuli. Increased expression of COX-2 is shown in non-small cell lung cancer (NSCLC), specifically in adenocarcinomas. Radiotherapy has been the important treatment for NSCLC. In recent studies, newer molecules that target specific pathophysiology or molecular pathways have been tested for the radiation sensitizers. COX-2 inhibitors are shown to enhanced radioresponse of cultured human cancer cell lines and immunodeficient mice. However, little is known about the molecular and biochemical mechanisms how NSAIDs enhance radioresponse of tumor cells. Nimesulide (methanesulfonamide, N-(4-nitro-2- phenoxyphenyl)), selective COX-2 inhibitors, is a drug with anti-inflammatory, anti-pyretic and analgesic properties. Nimesulide has the specific affinity to inhibit the inducible form of cyclooxygenase (COX-2) rather than the constitutive form (COX-1), and is well tolerated by adult, elderly and pediatric patients. Nimesulide was found also to have a chemopreventive activity against colon, urinary bladder, breast, tongue, and liver carcinogenesis. In this study, we examined whether nimesulide can increase radiation induced cell death and its mechanism in NSCLC cells A549.

    NSAIDs are frequently used in modern medicine to inhibit the COX enzymes and induce analgesic, antipyretic, anti-inflammatory, and antiplatelet effects. Concomitant treatment with two or more NSAIDs can lead to their competition for binding and inhibition of the COX enzymes and altered time course of the pharmacological effects. The competition between the low-dose aspirin and other NSAIDs for binding to COX-1 is described, including the recent findings on the differences in the interaction of NSAIDs with the individual COX-1 subunits, and the clinical consequences of this drug-drug interaction. The major pharmacokinetic (PK) and pharmacodynamic (PD) factors that govern the interaction of low-dose aspirin with other NSAIDs are explained, along with the approaches for prediction of the magnitude of this interaction using mechanism-based PK-PD modeling. Concomitant administration of other NSAIDs can diminish the antiplatelet effects of low-dose aspirin, increase the risk of thromboembolic effects (heart attacks and strokes), and lead to patient morbidity and mortality. The healthcare providers and the patients are seldom aware to this clinical problem and its consequences. Despite this drug interaction, low-dose aspirin possesses high clinical safety and it is not expected to be replaced by the recently approved drugs.

    Full Text Available Traditional healers in Pakistan use the herb Amberboa divaricata as tonic, aperiant, deobstruent, febrifuge, anti-diarrheal, antiperiodic, antipyretic, anti-cough and in skin disorders. In vitro tissue experiments were carried out on rabbit jejunum to elucidate the possible mechanism of its prescribed effects on gastrointestinal tract, while antibacterial and antioxidant experiments were performed to provide pharmacological evidence of its traditional use in skin disorders. The 70%methanolic crude extract of A. divaricata produced dose dependent relaxation in isolated rabbit jejunum tissue in a concentration range of 0.1–3.0 mg/mL (n=5. Calcium response curves were constructed at concen-tration of 0.03 and 0.1 mg/mL (n=5, which produced rightward shift in a pattern similar to that of verapamil, confirming the calcium channel blocking activity. Agar disc diffusion assay at a concentration of 10 mg crude extract/disc showed clear zones of inhibition.

    The presence of pharmaceutical drugs in aquatic ecosystems has been widely reported during the past years. Salicylic acid (SA) is mainly used in human medicine as an analgesic and antipyretic drug, being also active in preventing platelet aggregation. To study the ecotoxicological effects potentially elicited by SA in freshwater fish, brown trout individuals (Salmo trutta fario) were chronically exposed (28 days) to this drug, in order to evaluate the enzymatic and histological effects, in both gills and liver. A qualitative and semi-qualitative evaluation of the gills and liver was performed, and also a quantitative evaluation of various lamellar structures. Oxidative stress was quantified trough the determination of glutathione S-transferases (GSTs), glutathione reductase (GRed), total and selenium-dependent glutathione peroxidase (GPx) and Catalase (Cat) activities. Lipid peroxidative damage was also assessed by the quantification of thiobarbituric acid reactive substances (TBARS) in the liver. The here-obtained data showed the occurrence of oxidative stress, reflected by an increased activity of GPx and GRed in the liver; additionally, it was possible to observe non-specific histological changes in gills. The global significance of the entire set of results is discussed, giving emphasis to the ecological relevance of the responses.

This study assessed the prevalence of self-medication among the medical students in South India. The data was analysed using SPSS version 11.5. A total of 440 students were included in the study. The prevalence of self-medication was 78.6%. A larger number of females were self-medicating (81.2% than males (75.3%. The majority of the students self-medicated because of the illness being too trivial for consultation (70.5%. Antipyretics were most commonly self-medicated by the participants (74.8%. Only 47% of the participants opined that self-medication was a part of self-care and it needs to be encouraged. 39.3% of the participants perceived that the supply of medicine without prescription by the pharmacist can prevent the growing trend of self-medication. Easy availability and accessibility to health care facilities remains the cornerstone for reducing the practice of self-medication.

    Malaria cases are often misdiagnosis by clinicians in tropical areas like Indonesia. Some cases show overlapping signs and symptoms of another infection that are common in the tropical areas such as typhoid, dengue, and leptospirosis. It can be misdiagnosed in practice and led to a wrong management that can end fatally. Severe malaria is usually caused by Plasmodium falciparum. P. vivax can also cause severe malaria but the cases reported are uncommon. Since infections with severe P. vivax that generally results in serious disease is quite uncommon in Indonesia, their identification and management are important. We report a case of severe malaria with sepsis, renal injury and hepatic impairment associated with malaria in a 70-year-old male. Clinical manifestations included anemia, sepsis, and elevated serum creatinine, urea, total bilirubin, and procalcitonin. The rapid diagnostic test for malaria and microscopic examination of blood smears were positive for P. vivax. The patient was treated as severe malaria with intravenous artesunate for six days, followed by oral treatment of primaquine for 14 days. Intravenous fluid therapy, antipyretic, anti-malaria and antibiotic treatment were administered. The patient was stable and then discharged from the hospital. The prognosis depends much on early diagnosis and appropriate supportive treatment.

    Aegle marmelos, commonly known as Bael and belonging to the family Rutaceae is an important medicinal plant in the traditional Indian system of medicine, the Ayurveda. The extract prepared by boiling the bark, leaves or roots in water is useful as laxative, febrifuge, and expectorant. The extract is also useful in ophthalmia, deafness, inflammations, catarrh, diabetes, and asthmatic complaints. The fruits are used in treating diarrhea, dysentery, stomach ache, and cardiac ailments. Scientific studies have validated many of Bael's ethnomedicinal properties and its potential antimicrobial effects, hypoglycemic, astringent, antidiarrheal, antidysenteric, demulcent, analgesic, anti-inflammatory, antipyretic, wound-healing, insecticidal, and gastroprotective properties. In addition, studies have also shown that Bael and some of the Bael phytochemicals possess antineoplastic, radioprotective, chemoprotective, and chemopreventive effects, properties efficacious in the treatment and prevention of cancer. For the first time, the current review summarizes the results related to these properties and emphasizes aspects that require further investigation for Bael's safe and effective use in the near future.

    Full Text Available It is well-known that the modern history of salicylates began in 1899 when the compound acetylsalicylic acid was registered and introduced commercially as “aspirin” by the Bayer Company of Germany. As a matter of fact, however, remedies made from willow bark had been used to treat fever and rheumatic complaints at least since 1763, when Edward Stone described their efficacy against malarian fever. A number of Italian scientists made significant contributions during the long period of research leading up to the synthesis of acetylsalicylic acid and its widespread use in rheumatic diseases. In this paper we will review the contributions of some of these researchers, beginning with Bartolomeo Rigatelli, who in 1824 used a willow bark extract as a therapeutic agent, denominating it “salino amarissimo antifebbrile” (very bitter antipyretic salt. In the same year, Francesco Fontana described this natural compound, giving it the name “salicina” (salicin. Two other Italian chemists added considerably to current knowledge of the salicylates: Raffaele Piria in 1838, while working as a research fellow in Paris, extracted the chemical compound salicylic acid, and Cesare Bertagnini in 1855 published a detailed description of the classic adverse event associated with salicylate overdoses – tinnitus – which he studied by deliberately ingesting excessive doses himself. Bertagnini and above all Piria also played conspicuous roles in the history of Italy during the period of the Italian Risorgimento, participating as volunteers in the crucial battle of Curtatone and Montanara during the first Italian War of Independence.

    Full Text Available Context: Spermacoce verticillata, known as “poaia and vassourinha de botão”, is a species widely used in Brazilian traditional medicine as anti-inflammatory, antipyretic and analgesic. It is a native species, small, upright perennial, and broadly distributed throughout Brazil. Until now, few chemical studies have focused on the phenolic composition of this species. Aims: Evaluate the phytochemical profile of phenolic compounds from Spermacoce verticillata and search new compounds that have chemotaxonomic significance. Methods: Leaves of S. verticillata were extracted using distilled water. The extract (SVL was purified by several chromatography processes. Extract and compounds were analyzed by HPLC-DAD and NMR. Results: Phytochemical analysis led to identification, for the first time, of three compounds (1-3 for the specie. Chlorogenic acid (1 was identified by HPLC-DAD compared with reported in the literature. Quercetin-3-O-rutinoside (rutin (2 and kaempferol-3-O-rutinoside (3 were isolated from butanolic fraction and identified by spectroscopic analysis comparison with data reported in the literature. The flavonoid rutin is the major compound in SVL followed by kaempferol-3-O-rutinoside and chlorogenic acid. Conclusions: This is the first report for these compounds (1-3 in S. verticillata. The presence of these three new compounds indicates chemical markers of the species for this genus and family. This information is extremely important because increases the resources for chemotaxonomic classification of these species.

    Lichen secondary metabolites can function as allelochemicals and affect the development and growth of neighboring bryophytes, fungi, vascular plants, microorganisms, and even other lichens. Lichen overgrowth on bryophytes is frequently observed in nature even though mosses grow faster than lichens, but there is still little information on the interactions between lichens and bryophytes.In the present study, we used extracts from six lichen thalli containing secondary metabolites like usnic acid, protocetraric acid, atranorin, lecanoric acid, nortistic acid, and thamnolic acid. To observe the influence of these metabolites on bryophytes, the moss Physcomitrella patens was cultivated for 5 weeks under laboratory conditions and treated with lichen extracts. Toxicity of natural mixtures of secondary metabolites was tested at three selected doses (0.001, 0.01, and 0.1 %). When the mixture contained substantial amounts of usnic acid, we observed growth inhibition of protonemata and reduced development of gametophores. Significant differences in cell lengths and widths were also noticed. Furthermore, usnic acid had a strong effect on cell division in protonemata suggesting a strong impact on the early stages of bryophyte development by allelochemicals contained in the lichen secondary metabolites.Biological activities of lichen secondary metabolites were confirmed in several studies such as antiviral, antibacterial, antitumor, antiherbivore, antioxidant, antipyretic, and analgetic action or photoprotection. This work aimed to expand the knowledge on allelopathic effects on bryophyte growth.

    Full Text Available Pharmaceuticals constitute a large group of human and veterinary medicinal organic compounds which have long been used throughout the world. According to their therapeutic activity they are classified in several groups: antibiotics, analgesics/antipyretic, CNS (Central nervous system drugs, cardiovascular drugs, endocrinology treatments, diagnostic aid-adsorbable organic halogen compounds. Pharmaceuticals are designed to have a physiological effect on humans and animals in trace concentrations. Pharmaceuticals end up in soil, surface waters and eventually in ground water, which can be used as a source of drinking water, after their excretion (in unmetabolized form or as active metabolites from humans or animals via urine or faeces. The possible fates of pharmaceuticals once they get into the aquatic environment are mainly three: (i ultimately they are mineralized to carbon dioxide and water, (ii the compound does not degrade readily because it is lipophilic and is partially retained in the sedimentation sludge and (iii the compound metabolizes to a more hydrophilic molecule, passes through the wastewater treatment plant and ends up in receiving waters (which are surface waters, mainly rivers. These compounds exhibit the highest persistence in the environment. In recent years, and in particular after the use of the advanced measurement technologies, many pharmaceuticals have been identified worldwide and detected at ng/L levels (trace concentrations in the aquatic environment, and are considered as an emerging environmental problem due to their continuous input and persistence in the aquatic ecosystem even at low concentrations.

    Full Text Available In order to determine the clinical significance of Kikuchi Fujimoto Disease (histiocytic necrotizing lymhadenitis and to review the literature available on this condition, we selected the Medicine research papers in English language published between the years 1972 to 2011. Kikuchi Fujimoto Disease (KFD is an uncommon, cosmopolitan, benign and self-limiting condition with higher Japanese and Asian prevalence. Most of the sufferers of KFD are young people who seek treatment because of having acute tender cervical lymphadenopathy, low grade fever and night sweats. Coagulative necrosis with ample karyorrhetic debris in paracortical areas of the involved lymph nodes is the characteristic histologic feature of KFD. Diagnosing KFD is crucial as it can be mistaken for malignant lymphoma and SLE. KFD was put forth first time in 1972 by Dr. Masahiro Kikuchi and by Funimoto as lymphadenitis with reticular proliferation, histiocytes and abundant nuclear debris. It is a rare benign condition of lymph nodes and most of the clinicians and pathologists are unfamiliar with it. KFD is self-limiting disease (within 1 to 4 months, however, patients should be followed up regularly as it may crop up again or progress to SLE. Analgesics and antipyretics help to ameliorate the symptoms.

    Full Text Available Paracetamol is a non-steroidal anti-inflammatory drug used as an antipyretic agent for the alternative to aspirin. Conversely, the overdoses of paracetamol can cause hepatic toxicity and kidney damage. Hence, the determination of paracetamol receives much more attention in biological samples and also in pharmaceutical formulations. Here, we report a rapid and sensitive detection of the paracetamol based on screen-printed modified electrode (SPE with Cu nanocomplex (Cu in pH=7.0. The paracetamol is not stable in strong acidic and strong alkaline media, and is hydrolyzed and hydroxylated. However, it is stable in intermediate pHs due to the dimerization of paracetamol. The kinetics of the paracetamol oxidation was briefly studied and documented in the schemes. In addition, the characterization of Cu nanocomplex was probed by Fourier transform infrared spectroscopy (FT-IR, X-ray diffraction (XRD, scanning electron microscopy (SEM, and energy dispersive X-ray spectroscopy (EDX. Moreover, the voltammetry determined the paracetamol with the linear concentration ranging from 10.0 to 1000.0 μM and the lower detection limit of 1.0 μM. This method was also successfully used to detect the concentration of paracetamol in pharmaceutical formulations and urine samples.

    Piroxicam is a NSAID with analgesic and antipyretic properties, used for the treatment of rheumatoid diseases. The aim of this study was to evaluate the bioequivalence of two brands of piroxicam capsules (20 mg) in 24 Egyptian volunteers. The in vivo study was established according to a single-center, randomized, single-dose, laboratory-blinded, 2-period, 2-sequence, crossover study with a washout period of 3 weeks. Under fasting conditions, 24 healthy male volunteers were randomly selected to receive a single oral dose of one capsule (20 mg) of either test or reference product. Plasma samples were obtained over a 144-hour interval and analyzed for piroxicam by HPLC with UV detection. The pharmacokinetic parameters Cmax , tmax , AUC0-t , AUC0-∞ , Vd /F, Cl/F, and t1/2 were determined from plasma concentration-time profiles. The 90% confidence intervals for the ratio of log transformed values of Cmax , AUC0-t , and AUC0-∞ of the two treatments were within the acceptable range (0.8-1.25) for bioequivalence. From PK perspectives, the two piroxicam formulations were considered bioequivalent, based on the rate and extent of absorption. No adverse events occurred or were reported after a single 20-mg piroxicam and both formulations were well-tolerated. © 2014, The American College of Clinical Pharmacology.

    Cocos nucifera (L.) (Arecaceae) is commonly called the "coconut tree" and is the most naturally widespread fruit plant on Earth. Throughout history, humans have used medicinal plants therapeutically, and minerals, plants, and animals have traditionally been the main sources of drugs. The constituents of C. nucifera have some biological effects, such as antihelminthic, anti-inflammatory, antinociceptive, antioxidant, antifungal, antimicrobial, and antitumor activities. Our objective in the present study was to review the phytochemical profile, pharmacological activities, and toxicology of C. nucifera to guide future preclinical and clinical studies using this plant. This systematic review consisted of searches performed using scientific databases such as Scopus, Science Direct, PubMed, SciVerse, and Scientific Electronic Library Online. Some uses of the plant were partially confirmed by previous studies demonstrating analgesic, antiarthritic, antibacterial, antipyretic, antihelminthic, antidiarrheal, and hypoglycemic activities. In addition, other properties such as antihypertensive, anti-inflammatory, antimicrobial, antioxidant, cardioprotective, antiseizure, cytotoxicity, hepatoprotective, vasodilation, nephroprotective, and anti-osteoporosis effects were also reported. Because each part of C. nucifera has different constituents, the pharmacological effects of the plant vary according to the part of the plant evaluated.

    Full Text Available Parvovirus B19 can cause different skin rashes like maculopapular, erythematous, petechial, or purpuric lesions. In addition, parvovirus B19 can cause some important hematologic disorders like aplastic anemia, leukopenia, neutropenia, and thrombocytopenia. We report a child who was admitted to the hospital with petechial-purpuric rashes. On laboratory analysis, leukopenia and thrombocytopenia were found and serologic testing of parvovirus B19 IgM was determined to be positive. After the third day of hospitalization, the petechial-purpuric rashes began to decline and laboratory results were in the normal range. We think that the disease was parvovirus B19 infection. The patient was treated with only antipyretic drugs. On follow up, the clinical and laboratory findings had completely returned to normal. In conclusion, parvovirus B19 can cause clinical signs such as petechiae and purpura. Also, hematologic disorders may be a complication. Because of this, it should be considered in the differential diagnosis in patients with rash, thrombocytopenia, and leukopenia.

    Bronchopneumonia is the most common clinical manifestation of pneumonia in pediatric population and leading infectious cause of mortality in children under 5 years. Evaluation of treatment involves diagnostic procedures, assessment of disease severity and treatment for disease with an emphasis on vulnerability of the population. To determine the most commonly used antibiotics at the Pediatric Clinic in Sarajevo and concomitant therapy in the treatment of bronchopneumonia. The study was retrospective and included a total of 104 patients, hospitalized in pulmonary department of the Pediatric Clinic in the period from July to December 2014. The treatment of bronchopneumonia at the Pediatric Clinic was empirical and it conformed to the guidelines and recommendations of British Thoracic Society. First and third generation of cephalosporins and penicillin antibiotics were the most widely used antimicrobials, with parenteral route of administration and average duration of treatment of 4.3 days. Concomitant therapy included antipyretics, corticosteroids, leukotriene antagonists, agonists of β2 adrenergic receptor. In addition to pharmacotherapy, hospitalized patients were subjected to a diet with controlled intake of sodium, which included probiotic-rich foods and adequate hydration. Recommendations for further antimicrobial treatment include oral administration of first-generation cephalosporins and penicillin antibiotics. Results of the drug treatment of bronchopneumonia at the Pediatric Clinic of the University Clinical Center of Sarajevo are comparable to the guidelines of the British Thoracic Society. It is necessary to establish a system for rational use of antimicrobial agents in order to reduce bacterial resistance.

    Full Text Available The genus Citrus (Rutaceae includes several species of plants that produce some of the most cultivated fruits in the world, providing an appreciable content of essential oil. In folk medicine, they are used as a cholagogue, antipyretic, anti-inflammatory, sedative, and antitoxic effects. Lemon essential oil has been used since ancient times for its antiseptic, carminative, diuretic, and eupeptic effects. In this study, we investigated the anti-inflammatory activity of Citrus latifolia Tanaka essential oil (CLEO and its main constituent LIM. In the cell viability assay, CLEO and LIM (3, 10, 30, and 90 μg/mL had low cytotoxicity. In zymosan-induced peritonitis, LIM (500 mg/kg decreased the infiltration of peritoneal exudate leukocytes and decreased the number of polymorphonuclear leukocytes. In vitro chemotaxis revealed that CLEO and LIM (1, 3, and 10 µg/mL promoted a significant reduction of neutrophil migration toward fMLP and LTB4. LIM (500 mg/kg also reduced TNF-α levels but did not alter IL-10 levels in the peritoneal exudate. In conclusion, this study showed that LIM isolated from CLEO had potential anti-inflammatory effects, likely by inhibiting proinflammatory mediators present in inflammatory exudate and leukocyte chemotaxis.

In this study, cytotoxic and genotoxic effects of I. viscosa leaf extracts on the root meristem cells of Allium cepa have been examined. Onion bulbs were exposed to 2.5 mg/ml, 5 mg/ml, and 10 mg/ml concentrations of the extracts for macroscopic and microscopic analysis. Tap water has been used as a negative control and Ethyl methanesulfonate (EMS (2⋅10−2 M has been used as a positive control. The test concentrations have been determined according to doses which are recommended for use in alternative medicine. There has been statistically significant (P<.05 inhibition of root growth depending on concentration by the extracts when compared with the control groups. All the tested extracts have been observed to have cytotoxic effects on cell division in A. cepa. I. viscosa leaf extract induces the total number of chromosomal aberrations and micronuclei (MNC formations in A. cepa root tip cells significantly when compared with control groups. Also, this paper shows for the first time the induction of cell death, ghost cells, cells with membrane damage, and binucleated cells by extract treatment. These results suggest the cytotoxic and genotoxic effects of the I. viscosa leaf extracts on A. cepa.

    Chediak Higashi Syndrome (CHS) is a rare autosomal recessive disease, characterized by partial oculocutaneous albinism, frequent pyogenic infections, and the presence of abnormal large granules in leukocytes and other granule containing cells. The abnormal granules are readily seen in blood and marrow granulocytes. About 50% to 85% of patients eventually enter an accelerated phase, manifested by fever, lymphadenopathy, anemia, jaundice, neutropenia, thrombocytopenia, and widespread lymphohistiocytic organ infiltrates. The first accelerated phase of CHS may occur shortly after birth or several years later. Most patients undergo a variable period of recurrent infections before going into the accelerated phase. Therefore, primary presentation in the accelerated phase is unusual. This case was referred to our institution that is a tertiary care cancer centre, with a clinical diagnosis of lymphoma/leukemia. Hence this interesting case of CHS in accelerated phase at presentation is described. The child had 1-month history of fever, bilateral neck swellings, and loss of appetite. On the basis of the clinical presentation, hematologic, and histopathologic findings, a diagnosis of accelerated phase of CHS was made. The child was treated with antipyretics, antibiotics, and stem cell transplantation was suggested to him. When the child presents to a hospital with oculocutaneous albinism and recurrent infections, careful examination of the peripheral blood smear by an experienced morphologist cannot be overemphasized. A high degree of awareness and early recognition of the syndrome, could lead to the institution of the only possible curative treatment, bone marrow transplant, before the accelerated phase supervenes.

    The discovery of aspirin, an antipyretic, anti-inflammatory and analgesic drug, undoubtedly represents a milestone in the history of medical therapy. Since ancient times the derivatives of willow (Salix alba) were used to treat a variety of fevers and pain syndromes, although the first report dates back to 1763 when the English Reverend Edward Stone described the effect of an extract of the bark willow in treating malaria. In the XIX century many apothecaries and chemists, including the Italian Raffaele Piria and Cesare Bertagnini, developed the biological processes of extraction and chemical synthesis of salicylates, and then analyzed their therapeutic properties and pharmacokinetic and pharmacodynamic characteristics. In 1899 the Bayer Company, where Felix Hoffmann, Heinrich Dreser and Arthur Eichengrün worked, recorded acetyl-salicylic acid under the name "Aspirin". In the XX century, besides the definition of the correct applications of aspirin in the anti-rheumatic therapy being defined, Lawrence L. Crawen identified the property of this drug as an anti-platelet agent, thus opening the way for more widespread uses in cardiovascular diseases.

    Sparteine is a quinolizidine alkaloid (QA) produced by Lupine species that has generated much interest due to its anti-hypertensive, anti-pyretic, and anti-inflammatory properties. In the nervous system, sparteine has been shown to display anti-cholinergic and depressive activity, although how sparteine exerts its toxic effects in the brain remains unclear. We have addressed this issue by administering subcutaneous injections of sparteine (25 mg/kg of body weight) to rats on postnatal days 1 and 3, and then examining the expression of the muscarinic acetylcholine receptor (mAChR) subunits m1-m4 in the brains of the neonatal rats 14-60 days later. Administration of sparteine to neonatal rats caused neuronal damage in the cerebral motor cortex accompanied by transient changes in the expression of m1-m4 mAChR subunits as revealed by both RT-PCR and Western blotting. This effect could be prevented by pre-treatment with atropine (10 mg/kg) 1 h prior to the injection of sparteine, suggesting that the cytotoxic activity of sparteine is mediated through mAChRs.

    Flupirtine is a non-opioid analgesic without antipyretic or antiphlogistic properties but with favorable tolerability in humans. This analgesic also exhibits neuroprotective activities. Furthermore, flupirtine antagonizes glutamate- and NMDA-induced intracellular levels of Ca 2+ and counteracts the effects of focal cerebral ischemia. Although flupirtine has been used to relieve pain caused by different diseases and clinical procedures, information on the safety and efficacy of flupirtine is limited. The present study was conducted to investigate the neuroprotective effects of flupirtine on U373 malignant glioma (MG) cell lines. Cell viability and cell cycle analysis was performed by MTT assay and flow cytometry, respectively. Variations in the growth of U373 MG cells in 5 mM N-methyl-D-aspartate (NMDA), 1 mM flupirtine, and combined treatment indicated the antagonistic effects of NMDA and flupirtine on MG cell lines. The variation in the percentage of gated cell population in different cell cycle phases showed significant variations after 48 h of treatment. Flupirtine has neuroprotective effect of on U373 MG cells, which limits its use in the pain management of brain tumors. This property warrants further studies using animal models and large-scale clinical trials

    Full Text Available Actinidia callosa var. callosa has been widely used to treat antipyretic, analgesic, anti-inflammation, abdominal pain, and fever in Taiwan. The aim of this study was to evaluate the antioxidant, antinociceptive, and anti-inflammatory lipopolysaccharide-(LPS-induced nitric oxide (NO production in RAW264.7 macrophages and pawedema induced by λ-carrageenan activities of the methanol extract from A. callosa. In HPLC analysis, the fingerprint chromatogram of ethyl-acetate fraction of A. callosa (EAAC was established. EAAC showed the highest TEAC and DPPH radical scavenging activities, respectively. We evaluated that EAAC and the reference compound of catechin and caffeic acid decreased the LPS-induced NO production in RAW264.7 cells. Treatment of male ICR mice with EAAC significantly inhibited the numbers of acetic acid-induced writhing response and the formalin-induced pain in the late phase. Administration of EAAC showed a concentration-dependent inhibition on paw edema development after Carr treatment in mice. Anti-inflammatory mechanisms of EAAC might be correlated to the expression of inducible nitric oxide synthase (iNOS, cyclooxygenase-2 (COX-2, and heme oxygenase-1 (HO-1 in vitro and in vivo. Overall, the results showed that EAAC demonstrated antioxidant, antinociceptive, and anti-inflammatory activity, which supports previous claims of the traditional use for inflammation and pain.

    2013-11-01

    The genus Acronychia (Rutaceae) comprise 44 species, most of which are represented by shrubs and small trees, distributed in a wide geographical area of South-Eastern Asia comprising China, India, Malaysia, Indonesia, Australia, and the islands of the western Pacific Ocean. Most of the species of the genus Acronychia have been used for centuries as natural remedies in the ethnomedical traditions of indigenous populations as anti-microbial, anti-fungal, anti-spasmodic, stomachic, anti-pyretic, and anti-haemorragic agent. Moreover fruits and aerial parts are used as food in salads and condiments, while the essential oil obtained from flowers and leaves has been employed in cosmetics production. Phytochemicals isolated from Acronychia spp. include acetophenones, quinoline and acridone alkaloids, flavonoids, cinnamic acids, lignans, coumarins, steroids, and triterpenes. The reported biological activities of the above mentioned natural compounds refer to anti-plasmodial, anti-cancer, anti-oxidant, anti-inflammatory, anti-fungal, and neuroprotective effects. The aim of this review is to examine in detail from a phytochemical and pharmacologically point of view what is reported in the current literature about the properties of phytopreparations or individual active principles obtained from plants belonging to the Acronychia genus.

    2016-03-18

    Non-steroidal anti-inflammatory drugs (NSAIDs) are the most numerous category of drugs sharing the same mechanism of action and therapeutic activities (anti-inflammatory, analgesic and anti-pyretic). Despite having similar efficacy for pain relieve, the different available NSAIDs show variability in its safety profile. The risk of gastrointestinal and cardiovascular complications varies depending on the dose of NSAID and also the presence of different risk factors. It is necessary, therefore, an individualized case assessment before establishing the indication of the best NSAID for each patient, taking account of the best gastroprotection strategy. Improved prescription and enhanced treatment adherence are central objectives to reduce NSAID-related complications. A recent consensus of the Spanish Association of Gastroenterology and the Spanish societies of Cardiology and Rheumatology intends to promote the rational use of NSAIDs according to new recent studies. This review provides additional aspects to facilitate the optimal decision-making process in the routine use of these drugs in clinical practice. Copyright © 2015 Elsevier España, S.L.U.

    Aspirin has antipyretic and anti-inflammatory properties and is frequently used by pregnant and lactating women. However, its transfer in human milk when administered at low dose has not been reported. Research aim: This study aimed to evaluate the transfer of acetylsalicylic acid and its metabolite, salicylic acid, into human milk following the use of low dose aspirin. In this study, milk samples were collected at 0, 1, 2, 4, 8, 12, and 24 hours from seven breastfeeding women after a steady-state daily dose of 81 mg of aspirin. Milk levels of acetylsalicylic acid and salicylic acid were determined by liquid chromatography-tandem mass spectrometry. Acetylsalicylic acid levels were below the limit of quantification (0.61 ng/ml) in all the milk samples, whereas salicylic acid was detected at very low concentrations. The average concentration of salicylic acid observed was 24 ng/ml and the estimated relative infant dose was 0.4%. Acetylsalicylic acid transfer into milk is so low that it is undetectable even by highly sophisticated methodology. Salicylic acid does appear in the human milk in comparatively low amounts, which are probably subclinical in infants. Thus, the daily use of an 81-mg dose of aspirin should be considered safe during lactation.

    Background. Acetaminophen (APAP) is a commonly used analgesic and antipyretic. When administered in high doses, APAP is a clinical problem in the US and Europe, often resulting in severe liver injury and potentially acute liver failure. Studies have demonstrated that antioxidants and anti-inflammatory agents effectively protect against the acute hepatotoxicity induced by APAP overdose. Methods. The present study attempted to investigate the protective effect of B. trimera against APAP-induced hepatic damage in rats. The liver-function markers ALT and AST, biomarkers of oxidative stress, antioxidant parameters, and histopathological changes were examined. Results. The pretreatment with B. trimera attenuated serum activities of ALT and AST that were enhanced by administration of APAP. Furthermore, pretreatment with the extract decreases the activity of the enzyme SOD and increases the activity of catalase and the concentration of total glutathione. Histopathological analysis confirmed the alleviation of liver damage and reduced lesions caused by APAP. Conclusions. The hepatoprotective action of B. trimera extract may rely on its effect on reducing the oxidative stress caused by APAP-induced hepatic damage in a rat model. General Significance. These results make the extract of B. trimera a potential candidate drug capable of protecting the liver against damage caused by APAP overdose. PMID:25435714

  11. Role of non-steroidal anti-inflammatory drugs on intestinal permeability and nonalcoholic fatty liver disease.

    2017-06-14

    The use of non-steroidal anti-inflammatory drugs (NSAIDs) is widespread worldwide thanks to their analgesic, anti-inflammatory and antipyretic effects. However, even more attention is placed upon the recurrence of digestive system complications in the course of their use. Recent data suggests that the complications of the lower gastro-intestinal tract may be as frequent and severe as those of the upper tract. NSAIDs enteropathy is due to enterohepatic recycling of the drugs resulting in a prolonged and repeated exposure of the intestinal mucosa to the compound and its metabolites. Thus leading to so-called topical effects, which, in turn, lead to an impairment of the intestinal barrier. This process determines bacterial translocation and toxic substances of intestinal origin in the portal circulation, leading to an endotoxaemia. This condition could determine a liver inflammatory response and might promote the development of non-alcoholic steatohepatitis, mostly in patients with risk factors such as obesity, metabolic syndrome and a high fat diet, which may induce a small intestinal bacterial overgrowth and dysbiosis. This alteration of gut microbiota may contribute to nonalcoholic fatty liver disease and its related disorders in two ways: firstly causing a malfunction of the tight junctions that play a critical role in the increase of intestinal permeability, and then secondly leading to the development of insulin resistance, body weight gain, lipogenesis, fibrogenesis and hepatic oxidative stress.

    Full Text Available Background. There is an urgent need to develop new treatment strategies and drugs for pancreatic cancer that is highly resistant to radio-chemotherapy. Aesculus hippocastanum (the horse chestnut known in Chinese medicine as a plant with anti-inflammatory, antiedema, antianalgesic, and antipyretic activities. The main active compound of this plant is Escin (C54H84O23. Objective. To evaluate the effect of Escin alone and combined with chemotherapy on pancreatic cancer cell survival and to unravel mechanism(s of Escin anticancer activity. Methods. Cell survival was measured by XTT colorimetric assay. Synergistic effect of combined therapy was determined by CalcuSyn software. Cell cycle and induction of apoptosis were evaluated by FACS analysis. Expression of NF-κB-related proteins (p65, IκBα, and p-IκBα and cyclin D was evaluated by western blot analysis. Results. Escin decreased the survival of pancreatic cancer cells with IC50 = 10–20 M. Escin combined with gemcitabine showed only additive effect, while its combination with cisplatin resulted in a significant synergistic cytotoxic effect in Panc-1 cells. High concentrations of Escin induced apoptosis and decreased NF-κB-related proteins and cyclin D expression. Conclusions. Escin decreased pancreatic cancer cell survival, induced apoptosis, and downregulated NF-κB signaling pathway. Moreover, Escin sensitized pancreatic cancer cells to chemotherapy. Further translational research is required.

  14. Antimicrobial Properties of α-MSH and Related Synthetic Melanocortins

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available The natural antimicrobial peptides are ancient host defense effector molecules, present in organisms across the evolutionary spectrum. Several properties of α-melanocyte stimulating hormone (α-MSH suggested that it could be a natural antimicrobial peptide. α-MSH is a primordial peptide that appeared during the Paleozoic era, long before adaptive immunity developed and, like natural antimicrobial molecules, is produced by barrier epithelia, immunocytes, and within the central nervous system. α-MSH was discovered to have antimicrobial activity against two representative pathogens, Staphylococcus aureus and Candida albicans. The candidacidal influences of α-MSH appeared to be mediated by increases in cell cyclic adenosine monophosphate (cAMP. The cAMP-inducing capacity of α-MSH likely interferes with the yeast's own regulatory mechanisms of this essential signaling pathway. It is remarkable that this mechanism of action in yeast mimics the influences of α-MSH in mammalian cells in which the peptide binds to G-protein-linked melanocortin receptors, activates adenylyl cyclase, and increases cAMP. When considering that most of the natural antimicrobial peptides enhance the local inflammatory reaction, the anti-inflammatory and antipyretic effects of α-MSH confer unique properties to this molecule relative to other natural antimicrobial molecules. Synthetic derivatives, chemically stable and resistant to enzymatic degradation, could form the basis for novel therapies that combine anti-inflammatory and antimicrobial properties.

    Full Text Available New thiazolidine-4-one derivatives based on the 4-aminophenazone (4-amino-2,3-dimethyl-1-phenyl-3-pyrazolin-5-one scaffold have been synthesized as potential anti-inflammatory drugs. The pyrazoline derivatives are known especially for their antipyretic, analgesic and anti-inflammatory effects, but recently there were synthesized new compounds with important antioxidant, antiproliferative, anticancer and antidiabetic activities. The beneficial effects of these compounds are explained by nonselective inhibition of cyclooxygenase izoenzymes, but also by their potential scavenging ability for reactive oxygen and nitrogen species. The structure of the new compounds was proved using spectroscopic methods (FR-IR, 1H-NMR, 13C-NMR, MS. The in vitro antioxidant potential of the synthesized compounds was evaluated according to the ferric reducing antioxidant power, phosphomolydenum reducing antioxidant power, DPPH and ABTS radical scavenging assays. The chemical modulation of 4-aminophenazone (6 through linkage to thiazolidine-propanoic acid derivatives 5a–l led to improved antioxidant potential, all derivatives 7a–l being more active than phenazone. The most active compounds are the derivatives 7e, and 7k, which showed the higher antioxidant effect depending on the antioxidant assay considered.

    2008-01-01

    In the present experiments, a study of the radioprotective effects of natural antioxidants, rutin alone, vitamine E alone or each of them combined with synthetic radioprotector, cysteine have been investigated in irradiated and feverish irradiated rats. Furthermore, the oxidative stress bio markers and certain liver function tests of the irradiated and the feverish whole body irradiated rats were examined. Two main sets of animals were used: The 1st set was constructed in order to study the effect of irradiation, while the second set was used to study the effect of irradiation on feverish rats. The effect of irradiation was evaluated by exposing the whole body of rats to gamma radiation at acute single dose level of 6.5 Gy. Rutin was orally daily administered for two weeks before irradiation in a dose of 1.064 mmol/kg , vitamine E was injected intraperitoneally daily for seven days before irradiation in a dose of 50 mg/100 g. While, cysteine was intraperitoneally administered only 30 min. before irradiation in a dose of 30 mg/kg. In order to determine the antipyretic effect of the drugs, body temperature of each animal was measured before induction of hyperthermia as well as 18 hours following yeast injection. Rats were treated with the tested drugs before induction of fever then exposed to whole body gamma radiation at acute single dose level of 6.5 Gy and body temperature of each animal was measured 3 days after irradiation

    Paracetamol (APAP) is one of the most widely used and popular over-the-counter analgesic and antipyretic drugs in the world when used at therapeutic doses. APAP overdose can cause severe liver injury, liver necrosis and kidney damage in human beings and animals. Many studies indicate that oxidative stress is involved in the various toxicities associated with APAP, and various antioxidants were evaluated to investigate their protective roles against APAP-induced liver and kidney toxicities. To date, almost no review has addressed the APAP toxicity in relation to oxidative stress. This review updates the research conducted over the past decades into the production of reactive oxygen species (ROS), reactive nitrogen species (RNS), and oxidative stress as a result of APAP treatments, and ultimately their correlation with the toxicity and metabolism of APAP. The metabolism of APAP involves various CYP450 enzymes, through which oxidative stress might occur, and such metabolic factors are reviewed within. The therapeutics of a variety of compounds against APAP-induced organ damage based on their anti-oxidative effects is also discussed, in order to further understand the role of oxidative stress in APAP-induced toxicity. This review will throw new light on the critical roles of oxidative stress in APAP-induced toxicity, as well as on the contradictions and blind spots that still exist in the understanding of APAP toxicity, the cellular effects in terms of organ injury and cell signaling pathways, and finally strategies to help remedy such against oxidative damage.

  18. How respiratory diseases were treated at the beginning of the 19th century

    Full Text Available Respiratory diseases were quite common in the past. A treatment procedure for an acute respiratory disorder, most probably pneumonia, in a 72-year-old man was presented based on archival source materials dating from 1801. The treatment was provided by a doctor, barber surgeon “nurse” and pharmacist, who were practicing in Koniecpol in 1801. The patient was given mucolytic, antitussive, cardiac, antipyretic and analgesic medications and appetite stimulants. From the medical point of view that prevailed at that time, the treatment was correct. The patient was also given medications recommended under the humoral theory, which was still being followed at that time. According to that theory, the human body was thought to contain four humours: blood, phlegm, yellow bile and black bile. An imbalance of humours resulted in a disease. The treatment was designed to restore the proper humoral balance by techniques such as enemas, diuretics and bloodletting. From the present medical point of view, the treatment was incorrect. It caused anaemia and disturbances in water, electrolyte and acid-base homeostasis. The treatment resulted in the patient’s death. However, one can hardly blame doctor Tichi, as his treatment was fully compliant with the scientific views prevailing at that time.

    To examine the impact of providing rapid diagnostic tests for malaria on fever management in private drug retail shops where most poor rural people with fever present, with the aim of reducing current massive overdiagnosis and overtreatment of malaria. Cluster randomized trial of 24 clusters of shops. Dangme West, a poor rural district of Ghana. Shops and their clients, both adults and children. Providing rapid diagnostic tests with realistic training. The primary outcome was the proportion of clients testing negative for malaria by a double-read research blood slide who received an artemisinin combination therapy or other antimalarial. Secondary outcomes were use of antibiotics and antipyretics, and safety. Of 4603 clients, 3424 (74.4%) tested negative by double-read research slides. The proportion of slide-negative clients who received any antimalarial was 590/1854 (32%) in the intervention arm and 1378/1570 (88%) in the control arm (adjusted risk ratio 0.41 (95% CI 0.29 to 0.58), Pretail sector significantly reduced dispensing of antimalarials to patients without malaria, did not reduce prescribing of antimalarials to true malaria cases, and appeared safe. Rapid diagnostic tests should be considered for the informal private drug retail sector.Registration Clinicaltrials.gov NCT01907672. © Ansah et al 2015.

    Full Text Available Dactyloctenium aegyptium (L. P.B. (Yaa paak khwaai and Eleusine indica (L. Gaerth. (Yaa teen-ka have long been used in traditional Thai medicine because of their diuretic, anti-inflamatory, and antipyretic effects. The present study examined the antiproliferative and cytotoxic effects of the hexane and butanolic extracts of these two grass species. All the grass extracts exhibited selective growth inhibition effect on human lung cancer (A549 and cervical cancer (HeLa cells relative to normal human lung MRC-5 fibroblasts with IC50 values in a range of 202 to 845 mg/ml. Apparently, HeLa cellswere more sensitive to the extracts than A549 cells. Moreover, all the extracts induced lethality in both cancer cell lines atconcentrations close to 1,000 mg/ml, indicating their selective cytotoxicity effects. ELISA assay showed that only the hexaneextract of D. aegyptium (L. P.B. and E. indica (L. Gaerth. significantly increased the apoptotic level in extract-treatedA549 cells. However, DNA ladder assay detected classic DNA ladder patterns, a characteristic feature of apoptosis, in both cancer cell lines treated with all the extracts in a dose- and time-dependent manner. Taken together, these results indicatethat the cytotoxic activity of the grass extracts against lung and cervical cancer cells is mediated through the induction ofapoptosis.

    Cape gooseberry calyces (Physalis peruviana) have been used in folk medicine for their medicinal properties including anticancer, antimycobacterial, antipyretic, diuretic, immunomodulatory and antiinflammatory properties. The antiinflammatory effect was evaluated for extracts and fractions obtained from Physalis peruviana calyces in a mice model of acute inflammation. The fractions responsible for antiinflammatory activity were extracted for possible identification. The Physalis peruviana calyces were extracted by percolation with organic solvents. The primary hydroalcoholic fraction was purified by column chromatography. The antiinflammatory effect of extracts and fractions was evaluated using the 12-O-tetradecanoylphorbol-13-acetate-induced mouse model of ear edema. Thirty-eight secondary fractions were obtained by column chromatography of primary hydroalcoholic fraction. Six fractions, evaluated in 12-O-tetradecanoylphorbol-13-acetate-induced inflammation assay, showed significant antiinflammatory activity (p<0.05). The major fraction, Pp-D28-LF, showed a significant dose-dependent response at doses over 250 microg/ear. The antiinflammatory activity attributed to Physalis peruviana calyces was confirmed and validated its use in folk medicine. Fractions responsible for the antiinflammatory action were identified and seem promising for phytomedicinal development. Further studies are needed to isolate and identify the active constituents of these fractions as well as to ascertain the mechanisms involved in the antiinflammatory effect.

  4. Acetaminophen overdose associated with double serum concentration peaks

    2015-12-01

    Full Text Available Acetaminophen is the most commonly used analgesic–antipyretic medication in the United States. Acetaminophen overdose, a frequent cause of drug toxicity, has been recognized as the leading cause of fatal and non-fatal hepatic necrosis. N-Acetylcysteine is the recommended antidote for acetaminophen poisoning. Despite evidence on the efficacy of N-acetylcysteine for prevention of hepatic injury, controversy persists about the optimal duration of the therapy. Here, we describe the case of a 65-year-old male with acetaminophen overdose and opioid co-ingestion who developed a second peak in acetaminophen serum levels after completing the recommended 21-hour intravenous N-acetylcysteine protocol and when the standard criteria for monitoring drug levels was achieved. Prolongation of N-acetylcysteine infusion beyond the standard protocol, despite a significant gap in treatment, was critical for successful avoidance of hepatotoxicity. Delay in acetaminophen absorption may be associated with a second peak in serum concentration following an initial declining trend, especially in cases of concomitant ingestion of opioids. In patients with acetaminophen toxicity who co-ingest other medications that may potentially delay gastric emptying or in those with risk factors for delayed absorption of acetaminophen, we recommend close monitoring of aminotransferase enzyme levels, as well as trending acetaminophen concentrations until undetectable before discontinuing the antidote therapy.

    Chikungunya infection is treated symptomatically with antipyretics and anti-inflammatory drugs without any specific antiviral drug till date. The lack of an approved antiviral drug and the emergence of virulent strains after 2006 epidemics emphasize the need for the development of potential antiviral drugs to Chikungunya virus. Hence, we studied the antiviral activity of the extracts and compounds isolated from Tectona grandis leaves to both the Asian and East central South African strains of Chikungunya virus. Five compounds were isolated from the ethanolic extract of Tectona grandis by bioactivity guided fractionation followed by Spectral Characterisation through GC-MS and NMR spectroscopy and investigated for the antiviral activity. Also in silico ADMET and Molecular Docking of the characterised compounds against the structural and non structural proteins of Chikungunya virus were performed. The characterised compound Benzene-1-carboxylic acid hexadeconate was effective at IC 50 3.036μg/ml (7.5μM) and 76.46μg/ml (189.02μM) to Asian and ECSA strain of CHIKV respectively. The compound showed desirable pharmacokinetic properties and significant molecular interactions with the E1 protein of Chikungunya virus by in silico analysis. Thus Benzene-1-carboxylic acid-2-hexadeconate isolated from Tectona grandis was found to be a promising drug candidate to both the Asian and ECSA strains of Chikungunya virus with high selectivity indices in comparison to the reference RNA antiviral drug Ribavirin.

    Full Text Available Objective. To conduct a scoping review to characterize how fever is viewed in anthroposophic medicine (AM and discuss the scientific validity of these views. Methods. Systematic searches were run in Medline, Embase, CAMbase, and Google Scholar. Material from anthroposophic medical textbooks and articles was also used. Data was extracted and interpreted. Results. Most of the anthroposophic literature on this subject is in the German language. Anthroposophic physicians hold a beneficial view on fever, rarely suppress fever with antipyretics, and often use complementary means of alleviating discomfort. In AM, fever is considered to have the following potential benefits: promoting more complete recovery; preventing infection recurrences and atopic diseases; providing a unique opportunity for caregivers to provide loving care; facilitating individual development and resilience; protecting against cancer and boosting the anticancer effects of mistletoe products. These views are discussed with regard to the available scientific data. Conclusion. AM postulates that fever can be of short-term and long-term benefit in several ways; many of these opinions have become evidence-based (though still often not practiced while others still need empirical studies to be validated, refuted, or modified.

    Full Text Available Paracetamol (PM is an active metabolite of phenacetin and belongs to p-aminophenol derivatives. It is also termed as acetaminophen. PM is one of the non-steroidal anti-inflammatory drugs (NSAIDs which is used as an analgesic and antipyretic agent. It is an OTC drug and is used as a common household analgesic. It is not used as a substitute of aspirin or any other NSAIDs. It is a weak cyclooxygenase (COX 1 and 2 inhibitor but may inhibit COX-3 in the central nervous system. Many analytical techniques have been used for the assay of PM in pharmaceutical preparations and biological fluids. These techniques include spectrometry, chromatography, spectrofluorimetry, chemiluminescence, electrochemical techniques, flow injection spectrometry and chronoamperometry. In many pharmaceutical preparations PM is also used in combination with other drugs and these techniques have also been used for their simultaneous determination. A detailed review of various analytical techniques used for the assay of PM has been carried out which would be of great help to the chemists and pharmacists involved in the analysis and quality control of drugs.

    Full Text Available Lafoensia pacari A. St.-Hil., Lythraceae, a plant from the Cerrado known as pacari or dedaleiro, is widely used as an antipyretic, wound healing, anti-inflammatory, antidiarrheal and in the treatment of gastritis and cancer. Notable among the metabolite groups identified in leaves of L. pacari are the polyphenols, such as tannins and flavonoids, related to the pharmacological activities of pacari. Studies on the influence of environmental factors over production of major groups of secondary metabolites in pacari are important because they contribute data for its cultivation and harvest, and establish quantitative parameters of secondary metabolites in the plant drug. The objective of this study was to evaluate the influence of environmental factors on concentrations of phenolic metabolites in the leaves of L. pacari. Compounds quantified in the leaves were: total phenols, tannins by protein precipitation, hydrolysable tannins, total flavonoids, ellagic acid and mineral nutrients, while soil fertility was also analyzed, all over a period of one year. The data were analyzed using multivariate analysis, and the results suggest that metabolite concentrations in the leaves of this plant are influenced by seasonal factors, in particular the temperature and foliar micronutrients (Cu, Fe, Mn, Zn.

    Hemorrhagic fever with renal syndrome (HFRS) is due to an infection by the virus of the Hantavirus genus. Rodent hosts of Hantavirus are present in restricted areas in France; consequently, there are ecological niches and microepidemics of human Hantavirus infections. A HFRS case was diagnosed in the Paris region. The 11-year-old child had an acute debut fever-persistent despite antipyretic medication-asthenia, headache, abdominal pain, myalgia, thrombocytopenia, as well as renal failure with proteinuria. The diagnosis was made with a relevant clinical history and the specific serology of Puumala hantavirus. Therefore, a kidney biopsy was not necessary. What was interesting was the diagnostic approach because of the difference between the place and time of contamination and where the child became ill and developed the symptoms. The child was infected by Puumala hantavirus in Les Ardennes, a high-risk area, but became ill in the Paris region, an area with no prevalence. We review Hantavirus infections in France and its differential diagnosis. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Although poststroke central hyperthermia is common, prolonged instances are rare. We report a case of prolonged central fever after an intracranial hemorrhage. Before the accurate diagnosis and management of central fever, the patient underwent long-term antibiotic use that led to pseudomembranous colitis. Bromocriptine was used to treat the prolonged central hyperthermia, after which the fever did not exceed 39°C. A week later, the body temperature baseline was reduced to 37°C and a low-grade fever with minor temperature fluctuation occurred only a few times. No fever occurred in the month following the treatment. After the fever subsided, the patient could undergo an aggressive rehabilitation program.Keywords: bromocriptine, central hyperthermia, fever, stroke

    A series of 3,4-diaryloxazolones were prepared and evaluated for their ability to inhibit cyclooxygenase-2 (COX-2). Extensive structure-activity relationship work was carried out within this series, and a number of potent and selective COX-2 inhibitors were identified. The replacement of the methyl sulfone group on the 4-phenyl ring by a sulfonamide moiety resulted in compounds with superior in vivo antiinflammatory properties. In the sulfonamide series, the introduction of a methyl group at the 5-position of the oxazolone ring gave rise to very COX-2-selective compounds but with decreased in vivo activity. Selected 3,4-diaryloxazolones exhibited excellent activities in experimental models of arthritis and hyperalgesia. The in vivo activity of these compounds was confirmed with the evaluation of their antipyretic effectiveness and their ability to inhibit migration of proinflammatory cells. As expected from their COX-2 selectivity, most of the active compounds lacked gastrointestinal toxicity in vivo in rats after a 4-day treatment of 100 mg/kg/day. Within this novel series, sulfonamides 9-11 have been selected for further preclinical evaluation.

    Non-steroidal anti-inflammatory drugs (NSAID) are commonly used in sports medicine. NSAID have known anti-inflammatory, analgesic, antipyretic and antithrombotic effects, although their in-vivo effects in treating musculoskeletal injuries in humans remain largely unknown. NSAID analgesic action is not significantly greater than paracetamol for musculoskeletal injury but they have a higher risk profile, with side-effects including asthma exacerbation, gastrointestinal and renal side-effects, hypertension and other cardiovascular diseases. The authors recommend an approach to NSAID use in sports medicine whereby simple analgesia is preferentially used when analgesia is the primary desired outcome. However, based both on the current pathophysiological understanding of most injury presentations and the frequency that inflammation may actually be a component of the injury complex, it is premature to suppose that NSAID are not useful to the physician managing sports injuries. The prescribing of NSAID should be cautious and both situation and pathology specific. Both dose and duration minimisation should be prioritized and combined with simple principles of protection, rest, ice, compression, elevation (PRICE), which should allow NSAID-sparing. NSAID use should always be coupled with appropriate physical rehabilitation. NSAID are probably most useful for treating nerve and soft-tissue impingements, inflammatory arthropathies and tenosynovitis. They are not generally indicated for isolated chronic tendinopathy, or for fractures. The use of NSAID in treating muscle injury is controversial. Conditions in which NSAID use requires more careful assessment include ligament injury, joint injury, osteoarthritis, haematoma and postoperatively.

    Eurycoma longifolia jack (Tongkat Ali, Genus: Eurycoma; Family, Simaroubaceae) is one of the most popular tropical herbal plants. The plant contains a series of quassinoids, which are mainly responsible for its bitter taste. The plant extract, especially roots, are exclusively used (traditionally) for enhancing testosterone levels in men. The roots also have been used in indigenous traditional medicines for its unique anti-malarial, anti-pyretic, antiulcer, cytotoxic and aphrodisiac properties. As part of an on-going research on the bioactive compound of Eurycoma longifolia and evaluation for an optimized analysis method and parameter that influence in LC-MS analysis were carried out. Identification of the bioactive compounds was based on comparison of calculated retention time and mass spectral data with literature values. Examination of the Eurycoma longifolia sample showed some variations and differences in terms of parameters in LC-MS. However, combined method using methanol as the solvent with injection volume 1.0 μL and analysis in ultra scan mode and acetic acid as acidic modifier is the optimum method for LCMS analysis of Eurycoma longifolia because it successfully detected the optimum mass of compounds with good resolution and perfectly separated within a short analysis time.

    Self-medication is a common practice worldwide and the irrational use of drugs is a cause of concern. This study assessed the prevalence of self-medication among the medical students in South India. The data was analysed using SPSS version 11.5. A total of 440 students were included in the study. The prevalence of self-medication was 78.6%. A larger number of females were self-medicating (81.2%) than males (75.3%). The majority of the students self-medicated because of the illness being too trivial for consultation (70.5%). Antipyretics were most commonly self-medicated by the participants (74.8%). Only 47% of the participants opined that self-medication was a part of self-care and it needs to be encouraged. 39.3% of the participants perceived that the supply of medicine without prescription by the pharmacist can prevent the growing trend of self-medication. Easy availability and accessibility to health care facilities remains the cornerstone for reducing the practice of self-medication.

    Euphorbia hirta L. (Euphorbiaceae) (E. hirta) is a tree locally used as a traditional medicine in Africa and Australia to treat numerous diseases such as hypertension, respiratory ailments, tumors, wounds, antipyretic, anti-inflammatory activities, etc. Therefore, we undertook to investigate their immunomodulatory effect on T lymphocytes (CD3+, CD4+ and CD8+ receptors) and Th1 cytokines (IL-2, TNF-α, IFN-γ) in a dose-dependent manner. E. hirta ethanol extract at 25, 50, 100 and 200 mg/kg doses was given orally for 7 days from the day of immunization. E. hirta maximum inhibition at 100 and 200 mg/kg p.o. was found to significantly block the production of the cell-mediated immune response, (CD3+, CD4+ and CD8+ receptors) and (IL-2, TNF-α, IFN-γ) and also prolongs graft rejection. E. hirta also showed a decrease of delayed hypersensitivity (DTH) response and dose-related decrease in the primary antibody response, respectively. Based on the data, it can be suggested that E. hirta is a potent and non-toxic immunosuppressor, which can be further explored for the development of potent immunosuppressor.

    Despite extensive research into inflammatory diseases to date, no drugs with favourable safety profiles are available for treatment. Euphorbia hirta (E. hirta) is a tree that is locally used as a traditional medicine in Africa and Australia to treat numerous diseases such as hypertension, antipyretic and anti-inflammatory activities. The aim of the present study was to determine the potential anti-arthritic effects of E. hirta in mouse models of adjuvant induced arthritis (AIA). We treated BALB/c mice with (p.o.) E. hirta (25, 50, 100, and 200 mg/kg) daily (13 days) beginning at the onset of AIA. We examined the effect of E. hirta on key mediators of arthritic-inflammation, including pro-inflammatory (IL-2, IFN-γ, and TNF-α) and anti-inflammatory (IL-4 and IL-5) cytokines, T-cell activation markers (CD25/CD69), and co-stimulatory molecules (CD80/CD86). We also examined the inflammatory mediators (PGE2 and LTB4) response. E. hirta-treated mice showed a substantial reduction in the levels of pro-inflammatory cytokines, down regulated cell activation markers and co-stimulatory molecules, and up regulated anti-inflammatory cytokines. E. hirta decreased the levels of inflammatory-mediators in AIA animals. Supplementation with an E. hirta extract may be a promising treatment for arthritic and inflammatory diseases.

    Linarin is a flavone glycoside in the plants Flos chrysanthemi indici, Buddleja officinalis, Cirsium setosum, Mentha arvensis and Buddleja davidii, and has been reported to possess analgesic, antipyretic, anti-inflammatory and neuroprotective activities. In this paper, linarin was investigated for its AChE inhibitory potential both in-vitro and ex-vivo. Ellman’s colorimetric method was used for the determination of AChE inhibitory activity in mouse brain. In-vitro assays revealed that linarin inhibited AChE activity with an IC50 of 3.801 ± 1.149 μM. Ex-vivo study showed that the AChE activity was significantly reduced in both the cortex and hippocampus of mice treated intraperitoneally with various doses of linarin (35, 70 and 140 mg/Kg). The inhibition effects produced by high dose of linarin were the same as that obtained after huperzine A treatment (0.5 mg/Kg). Molecular docking study revealed that both 4’-methoxyl group and 7-O-sugar moiety of linarin played important roles in ligand-receptor binding and thus they are mainly responsible for AChE inhibitory activity. In view of its potent AChE inhibitory activity, linarin may be a promising therapeutic agent for the treatment of some diseases associated with AChE, such as glaucoma, myasthenia gravis, gastric motility and Alzheimer’s disease.

    Bryophytes are the second largest group of land plants after angiosperms. There is very less knowledge available about medicinal properties of these plants. Bryophytes are popular remedy among the tribal people of different parts of the world. Tribal people use these plants to cure various ailments in their daily lives. Bryophytes are used to cure hepatic disorders, skin diseases, cardiovascular diseases, used as antipyretic, antimicrobial, wound healing and many more other ailments by different tribal communities of Africa, America, Europe, Poland, Argentina, Australia, New Zealand, Turkey, Japan, Taiwan, Pakistan, China, Nepal and different parts of South, North and Eastern India. Apart from ethno-medicinal uses some bryophytes possesses antitumor activities against different cancer cell lines and this property of bryophytes needs to be more focused in the future. Compile information about medicinal properties and anticancer properties of bryophytes is lacking till date. In the present review, the authors tried to compile all the ethno-medicinal and other related information of bryophytes and fill the knowledge lacuna in this particular field. Some published reviews are available but the information is segregated. This manuscript will help people doing research in the bryophytes.

    Full Text Available The discovery of aspirin, an antipyretic, anti-inflammatory and analgesic drug, undoubtedly represents a milestone in the history of medical therapy. Since ancient times the derivatives of willow (Salix alba were used to treat a variety of fevers and pain syndromes, although the first report dates back to 1763 when the English Reverend Edward Stone described the effect of an extract of the bark willow in treating malaria. In the XIX century many apothecaries and chemists, including the Italian Raffaele Piria and Cesare Bertagnini, developed the biological processes of extraction and chemical synthesis of salicylates, and then analyzed their therapeutic properties and pharmacokinetic and pharmacodynamic characteristics. In 1899 the Bayer Company, where Felix Hoffmann, Heinrich Dreser and Arthur Eichengrün worked, recorded acetyl-salicylic acid under the name “Aspirin”. In the XX century, besides the definition of the correct applications of aspirin in the anti-rheumatic therapy being defined, Lawrence L. Crawen identified the property of this drug as an anti-platelet agent, thus opening the way for more widespread uses in cardiovascular diseases.

    Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a hypersensitivity reaction associated with a variety of drugs, mainly anticonvulsants, which is characterized by systemic symptoms and erythematous lesions, common to other toxicodermas. It is an uncommon clinical entity that requires a high suspicion by clinical staff given its varied initial presentation, and the fact that symptoms can overlap with those of other adverse cutaneous reactions to drugs. Without early diagnosis and appropriate treatment, mortality increases.We report the case of a 22-year-old patient with impaired neurodevelopment who received treatment with carbamazepine. Two months later he presented with general symptoms and skin erythematous lesions that began on his trunk. The patient received outpatient care with antihistamines and antipyretics without an appropriate response. His case progressed with increased skin lesions and systemic symptoms that met the diagnostic criteria for DRESS syndrome. He was hospitalized and received medical treatment according to recommended guidelines. The patient's condition improved as his symptoms and associated complications resolved. He was discharged with gradual clearing of the steroid therapy.

    Plants are used worldwide for the treatment of diseases, and novel drugs continue to be developed through research from plants. There are more than 20,000 species of plants used in traditional medicines, and these are all potential reservoirs for new drugs. Cucurbita pepo has been used in traditional folk medicine to treat cold and alleviate ache. Previous pharmacological tests have shown that it possesses antiviral, anti-inflammatory, and analgesic effects. Also, Solanum nigrum has been used as a diuretic and an antipyretic agent and it has also been used to cure inflammation, edema, mastitis and hepatic cancer. In this investigation, cytotoxicity of specific concentrations of hydro-alcoholic extracts of C. pepo and S. nigrum was studied on normal [Chinese hamster ovarian cells (CHO) and rat fibroblast] and cancer (HepG2 and CT26) cell lines. The cytotoxic effects and IC50 of the extracts on the selected cell lines were studied followed by colonogenic assay method. The results showed that IC50 of S. nigrum extract was significantly lower than that of the C. pepo extract on all four cell lines (P < 0.05). On the other hand, IC50 of S. nigrum extract was significantly higher than the extract of Taxus baccata and Cisplatin, herbal and chemical control positive anticancer compounds, respectively, on all four cell lines (P < 0.05). As a result, it is concluded that the extract of S. nigrum has almost similar cytotoxicity to the extract of T. baccata on cancer cells. PMID:20931075

    Monitoring sales of medications is a potential candidate for an early signal of a seasonal influenza epidemic. To test this theory, the data from a traditional, consultation-oriented influenza surveillance system were compared to medication sales and a predictive model was developed. Weekly influenza-like incidence rates from the National Influenza Sentinel Surveillance System were compared to sales of seven groups of medications (nasal decongestants, medicines for sore throat (MST), antitussives, mucolytics, analgo-antipyretics, non-steroidal anti-inflamatory drugs (NSAIDs), betalactam antibiotics, and macrolide antibiotics) to determine the correlation of medication sales with the sentinel surveillance system - and therefore their predictive power. Poisson regression and regression tree approaches were used in the statistical analyses. The fact that NSAIDs do not exhibit any seasonality and that prescription of antibiotics requires a visit to the doctor's office makes the two medication groups inappropriate for predictive purposes. The influenza-like illness (ILI) curve is the best matched by the mucolytics and antitussives sales curves. Distinct seasonality is also observed with MST and decongestants. The model including these four medication groups performed best in prediction of ILI incidence rate using the Poisson regression model. Sales of antitussives proved to be the best single predictive variable for regression tree model. Sales of medication groups included in the model were demonstrated to have a predictive potential for early detection of influenza season. The quantitative information on medication sales proves to be a useful supplementary system, complementing the traditional consultation-oriented surveillance system.

    Cleome viscosa Linn. (Capparidaceae), commonly known as "wild or dog mustard," is an annual, sticky herb found as a common weed all over the plains of India and throughout the tropics of the world. The whole plant and its parts (leaves, seeds, and roots) are widely used in traditional and folkloric systems of medicine. In traditional systems of medicine the plant is reported to possess beneficial effects as an anthelmintic, antiseptic, carminative, antiscorbutic, sudorific, febrifuge, and cardiac stimulant. Following the various traditional claims for the use of C. viscosa (CV) as a cure of numerous diseases, considerable efforts have been made by researchers to verify its utility through scientific pharmacological screenings. The pharmacological studies have shown that CV possesses various notable biological activities such as anthelmintic, antimicrobial, analgesic, antiinflammatory, immunomodulatory, antipyretic, psychopharmacological, antidiarrheal, and hepatoprotective activities. A wide variety of phytoprinciples have been isolated from the plant. The present review is an effort to consolidate traditional, ethnobotanical, phytochemical, and pharmacological information available on C. viscosa.

    Psychogenic fever is a stress-related, psychosomatic disease especially seen in young women. Some patients develop extremely high core body temperature (Tc) (up to 41°C) when they are exposed to emotional events, whereas others show persistent low-grade high Tc (37–38°C) during situations of chronic stress. The mechanism for psychogenic fever is not yet fully understood. However, clinical case reports demonstrate that psychogenic fever is not attenuated by antipyretic drugs, but by psychotropic drugs that display anxiolytic and sedative properties, or by resolving patients' difficulties via natural means or psychotherapy. Animal studies have demonstrated that psychological stress increases Tc via mechanisms distinct from infectious fever (which requires proinflammatory mediators) and that the sympathetic nervous system, particularly β3-adrenoceptor-mediated non-shivering thermogenesis in brown adipose tissue, plays an important role in the development of psychological stress-induced hyperthermia. Acute psychological stress induces a transient, monophasic increase in Tc. In contrast, repeated stress induces anticipatory hyperthermia, reduces diurnal changes in Tc, or slightly increases Tc throughout the day. Chronically stressed animals also display an enhanced hyperthermic response to a novel stress, while past fearful experiences induce conditioned hyperthermia to the fear context. The high Tc that psychogenic fever patients develop may be a complex of these diverse kinds of hyperthermic responses. PMID:27227051

    Aspirin is a commonly used medicine as an effective antipyretic, analgesic and anti-inflammatory drug. Previous studies have demonstrated its potential effects of anti-postmenopausal osteoporosis, while the molecular mechanisms remain unclear. The effects of aspirin on receptor‑activator of nuclear factor κB (NF‑κB) ligand (RANKL)‑induced osteoclasts were investigated in RAW264.7 cells in the current study. Using tartrate‑resistant acid phosphatase (TRAP) staining, it was observed that aspirin inhibited the differentiation of RANKL‑induced RAW264.7 cells. The mRNA expression of osteoclastic marker genes, including cathepsin K, TRAP, matrix metalloproteinase 9 and calcitonin receptor, were suppressed by aspirin as identified using reverse transcription‑quantitative polymerase chain reaction analysis. The immunofluorescence assay indicated that aspirin markedly inhibited NF‑κB p65 translocation to the nucleus in RANKL‑induced RAW264.7 cells. In addition, aspirin also suppressed the phosphorylation of mitogen‑activated protein kinases (MAPKs), observed by western blot analysis. Taken together, these data identified that aspirin inhibits osteoclastogenesis by suppressing the activation of NF‑κB and MAPKs in RANKL‑induced RAW264.7 cells, implying that aspirin may possess therapeutic potential for use in the prevention and treatment of osteoporosis.

    Full Text Available Schinus molle L., also known as pepper tree, has been reported to have antimicrobial, antifungal, anti-inflammatory, antispasmodic, antipyretic, antitumoural and cicatrizing properties. This work studies supercritical fluid extraction (SFE to obtain volatile and non-volatile compounds from the aerial parts of Schinus molle L. and the influence of the process on the composition of the extracts. Experiments were performed in a pilot-scale extractor with a capacity of 1 L at pressures of 9, 10, 12, 15 and 20 MPa at 323.15 K. The volatile compounds were obtained by CO2 supercritical extraction with moderate pressure (9 MPa, whereas the non-volatile compounds were extracted at higher pressure (12 to 20 MPa. The analysis of the essential oil was carried out by GC-MS and the main compounds identified were sabinene, limonene, D-germacrene, bicyclogermacrene, and spathulenol. For the non-volatile extracts, the total phenolic content was determined by the Folin-Ciocalteau method. Moreover, one of the goals of this study was to compare the experimental data with the simulated yields predicted by a mathematical model based on mass transfer. The model used requires three adjustable parameters to predict the experimental extraction yield curves.

  12. Dengue fever and dengue haemorrhagic fever in adolescents and adults.

    2012-05-01

    Dengue fever (DF) is endemic in tropical and subtropical zones and the prevalence is increasing across South-east Asia, Africa, the Western Pacific and the Americas. In recent years, the spread of unplanned urbanisation, with associated substandard housing, overcrowding and deterioration in water, sewage and waste management systems, has created ideal conditions for increased transmission of the dengue virus in tropical urban centres. While dengue infection has traditionally been considered a paediatric disease, the age distribution of dengue has been rising and more cases have been observed in adolescents and adults. Furthermore, the development of tourism in the tropics has led to an increase in the number of tourists who become infected, most of whom are adults. Symptoms and risk factors for dengue haemorrhagic fever (DHF) and severe dengue differ between children and adults, with co-morbidities and incidence in more elderly patients associated with greater risk of mortality. Treatment options for DF and DHF in adults, as for children, centre round fluid replacement (either orally or intravenously, depending on severity) and antipyretics. Further data are needed on the optimal treatment of adult patients.

    2016-06-01

    Full Text Available Over the past few years, residual pharmaceuticals (antibiotics, anticonvulsants, antipyretics drugs, hormones have begun to be considered as emerging environmental pollutants due to their continuous input and persistence to aquatic ecosystem even at low concentrations. Therefore, the development of efficient, cost-effective, and stable methods and materials for the wastewaters treatment have gained more recognition in recent years. In the path of meeting these developments, nanomaterials have attracted much attention as economical, convenient and ecofriendly tools for removing of pharmaceuticals from the hospital wastewaters because of their unique properties. The present review deals with recent advances in removal and/or destruction of residual pharmaceutical in wastewater samples using nanomaterials including metal nanoparticles, carbon nanotubes and nanofilters. In spite of using a variety of nanomaterials to remove the residual of pharmaceuticals, there is still a dearth of successful applicability of them in industrial processes. Therefore, some defects of nanomaterials to be used for the removal of pharmaceutical contaminate in environmental samples and their impacts on human health and environment is briefly discussed.

    Full Text Available Abstract Background Although the incidence of serious morbidity with childhood pneumonia has decreased over time, empyema as a complication of community-acquired pneumonia continues to be an important clinical problem. We reviewed the epidemiology and clinical management of empyema at 8 pediatric hospitals in a period before the widespread implementation of universal infant heptavalent pneumococcal vaccine programs in Canada. Methods Health records for children Results 251 children met inclusion criteria; 51.4% were male. Most children were previously healthy and those ≤ 5 years of age comprised 57% of the cases. The median length of hospitalization was 9 days. Admissions occurred in all months but peaked in winter. Oxygen supplementation was required in 77% of children, 75% had chest tube placement and 33% were admitted to an intensive care unit. While similarity in use of pain medication, antipyretics and antimicrobial use was observed, a wide variation in number of chest radiographs and invasive procedures (thoracentesis, placement of chest tubes was observed between centers. The most common organism found in normally sterile samples (blood, pleural fluid, lung biopsy was Streptococcus pneumoniae. Conclusion Empyema occurs most commonly in children under five years and is associated with considerable morbidity. Variation in management by center was observed. Enhanced surveillance using molecular methods could improve diagnosis and public health planning, particularly with regard to the relationship between immunization programs and the epidemiology of empyema associated with community-acquired pneumonia in children.

    A chikungunya outbreak took place in the State of Yucatan starting in the second half of 2015 OBJECTIVE: To analyse the clinical course of a case of chikungunya in a previously healthy infant, providing practical evidence to guide future diagnoses and treatment during outbreak seasons in endemic areas Clinical manifestation started with a sudden onset of fever and a diffuse macular-papillary erythema, originally treated in the community with non-steroidal anti-inflammatory drugs. Two days later, the fever relapsed with hypoactivity, severe thrombocytopenia and neutropenia (without lymphopenia), respiratory distress, liver dysfunction, sepsis, followed by septic shock with a fatal outcome. IgM test was positive to chikungunya, while her mother tested negative. Pseudomonas aeruginosa was isolated from the blood culture possible due to contamination, without ruling out the possibility of a mixed origin sepsis. Chikungunya is a disease in which the manifestations in neonates and young infants can be severe, and even fatal. It is important to suspect it in this age group at risk of vector contact, in the presence of fever without apparent source of infection and cutaneous manifestations. It is important to use the antipyretics cautiously, considering the possibility of aggravating the underlying infection, and the potential hepatic and haematological damage.

    Dengue is a common pathogenic disease often proving fatal, more commonly affecting the tropics. Aedes mosquito is the vector for this disease, and outbreaks of dengue often cause mass damage to life. The current review is an effort to present an insight into the causes, etiology, symptoms, transmission, diagnosis, major organs affected, mitigation and line of treatment of this disease with special emphasis on drugs of natural origin. The disease has a potential to spread as an endemic, often claiming several lives and thus requires concerted efforts to work out better treatment options. Traditional medicine offers an alternative solution and could be explored as a safer treatment option. Development of a successful vaccine and immunization technique largely remains a challenge and a better antiviral approach needs to be worked out to complement the supportive therapy. No single synthetic molecule has found to be wholly effective enough to offer curative control and the line of treatment mostly utilizes a combination of fluid replacement and antipyretics-analgesics like molecules to provide symptomatic relief.

    Full Text Available Background and objectives: Stevia rebaudiana has been used in medicine as anti-inflammatory, antioxidant, antipyretic, anti-fungal, and antibacterial agent. The present study was conducted to investigate the healing effects of S. rebaudiana ethanol extracts on cutaneous wounds in rats. Methods: Full-thickness excisional wounds (2×2 cm were induced on the back of 32 rats. The rats were divided into four groups as follows; untreated (control and treated with 1 mL basal cream, 1 mL S. rebaudiana ethanol extract 10%, and 1 mL tetracycline (3% for 20 days (short term. Animals of each group were euthanized at 20 day post-injury and wounds were assessed through macroscopic and microscopic analyses. Results: During the experiment, S. rebaudiana indicated a significant reduction in the wound area compared to other groups. Parameters such as arrangement of the healing tissue, re-epithelilization and epithelial formation demonstrated considerable changes when compared to the control. In addition, treatment with S. rebaudiana decreased the total number of cells, fibrocytes/fibroblasts ratio, neutrophils, and lymphocytes and enhanced the number of blood vessels and fibroblasts at 20 day. Conclusion: The present study demonstrated the wound healing activity of S. rebaudiana, lending credence to the folkloric use in the treatment of cutaneous wounds.

    The effect of Withania somnifera L. Dunal root powder on paw volume and serum lysosomal enzyme activities was investigated in monosodium urate crystal-induced rats. The levels of beta-glucuronidase and lactate dehydrogenase were also measured in monosodium urate crystal incubated polymorphonuclear leucocytes (PMNL). A significant increase in the level of paw volume and serum lysosomal enzymes was observed in monosodium urate crystal-induced rats. The increased beta-glucuronidase and lactate dehydrogenase level were observed in untreated monosodium urate crystal incubated polymorphonuclear leucocytes. On treatment with the W. somnifera root powder (500/1000 mg/kg body weight), the above changes were reverted back to near normal levels. W. somnifera also showed potent analgesic and antipyretic effect with the absence of gastric damage at different dose levels in experimental rats. For comparison purpose, non-steroidal anti-inflammatory drug (NSAID) indomethacin was used as a standard. These results provide evidence for the suppressive effect of W. somnifera root powder by retarding amplification and propagation of the inflammatory response without causing any gastric damage.

    In Argentina, there are numerous native species which are an important source of natural products and which are traditionally used in medicinal applications. Some of these species are going through an intense extraction process in their natural habitat which may affect their genetic diversity. The aim of this study was to establish vegetative propagation systems for three native forestal species of medicinal interest. This will allow the rapid obtainment of plants to preserve the germplasm. This study included the following species which are widely used in folk medicine and its applications: Erythrina crista-galli or "seibo" (astringent, used for its cicatrizant properties and for bronchiolitic problems); Acacia caven or "espinillo" (antirheumatic, digestive, diuretic and with cicatrizant properties) and Salix humboldtiana or "sauce criollo" (antipyretic, sedative, antispasmodic, astringent). The methodology included the micropropagation of seibo, macro and micropropagation of Salix humboldtiana and the somatic embryogenesis of Acacia caven. The protocol for seibo regeneration was adjusted from nodal sections of seedlings which were obtained from seeds germinated in vitro. The macropropagation through rooted cuttings of "sauce criollo" was achieved and complete plants of this same species were obtained through both direct and indirect organogenesis using in vitro cultures. The somatic embryogenesis for Acacia caven was optimized and this led to obtain a high percentage of embryos in different stages of development. We are able to support the conservation of native forest resources of medicinal use by means of vegetative propagation techniques.

    The use of medicinal plants with therapeutics properties represents a secular tradition in different cultures, mainly in underdeveloped countries. Lantana camara Linn and Lantana montevidensis Briq (Verbenaceae) found in tropical and subtropical areas around the world are popularly known as “camará” or “chumbinho.” In popular medicines, both plants are used as antipyretic and carminative and in the treatment of respiratory system infections. In this study, the antibacterial activity of the ethanolic extracts of L. camara and L. montevidensis leaves and roots against gram-positive and gram-negative strains standard and multi-resistant bacteria isolated from clinical material are presented. In order to determine the minimal inhibitory concentration (MIC), the microdilution method was used. The extracts demonstrated antibacterial activity against all tested bacteria, but the L. montevidensis fresh leaves extract present the best result against P. aeruginosa (MIC 8 μg/mL) and against multi-resistant E. coli (Ec 27) (MIC 16 μg/mL). These results drive new researches with both species in order to isolate the constituents responsible for the activity. PMID:21331189

    Acetylsalicylic acid (ASA) is one of the most commonly used drugs in the world due to its anti-inflammatory, analgesic, and antipyretic properties. This review aims to describe the relationship between acetylsalicylic acid and age-related macular degeneration (AMD) - a chronic disease that causes deterioration of visual acuity and is one of the most common ophthalmological diseases these days. Data presented in this review were collected from both research and review articles concerning ophthalmology and pharmacology. The results of the studies analyzed in this review are not unambiguous. Moreover, the studies are not homogenous. They differed from one another in terms of the number of patients, the age criteria, the ASA dose, and the duration of control period. The reviewed studies revealed that ASA therapy, which is applied as a protection in cardiovascular diseases in patients with early forms of AMD and geographic atrophy, should not be discontinued. On the basis of the present studies, it cannot be unequivocally said whether ASA influences people's vision and if people endangered with AMD progression or who are diagnosed with AMD should use this drug. It may increase the risk of AMD, but it can also reduce the risk of life-threatening conditions. The authors suggest that in order to avoid possible risks of AMD development, people who frequently take ASA should have their vision checked regularly.

    Full Text Available Higher plants are the source of a wide array of bioactive compounds that support skin integrity and health. Hibiscus syriacus, family Malvaceae, is a plant of Chinese origin known for its antipyretic, anthelmintic, and antifungal properties. The aim of this study was to assess the healing and hydration properties of H. syriacus ethanolic extract (HSEE. We established a cell culture from Hibiscus syriacus leaves and obtained an ethanol soluble extract from cultured cells. The properties of the extract were tested by gene expression and functional analyses on human fibroblast, keratinocytes, and skin explants. HSEE treatment increased the healing potential of fibroblasts and keratinocytes. Specifically, HSEE significantly stimulated fibronectin and collagen synthesis by 16 and 60%, respectively, while fibroblasts contractility was enhanced by 30%. These results were confirmed on skin explants, where HSEE accelerated the wound healing activity in terms of epithelium formation and fibronectin production. Moreover, HSEE increased the expression of genes involved in skin hydration and homeostasis. Specifically, aquaporin 3 and filaggrin genes were enhanced by 20 and 58%, respectively. Our data show that HSEE contains compounds capable of stimulating expression of biomarkers relevant to skin regeneration and hydration thereby counteracting molecular pathways leading to skin damage and aging.

    To assess the quality and safety of having community health workers (CHWs) in rural Zambia use rapid diagnostic tests (RDTs) and provide integrated management of malaria and pneumonia. In the context of a cluster-randomized controlled trial of two models for community-based management of malaria and/or non-severe pneumonia in children under 5 years old, CHWs in the intervention arm were trained to use RDTs, follow a simple algorithm for classification and treat malaria with artemether-lumefantrine (AL) and pneumonia with amoxicillin. CHW records were reviewed to assess the ability of the CHWs to appropriately classify and treat malaria and pneumonia, and account for supplies. Patients were also followed up to assess treatment safety. During the 12-month study, the CHWs evaluated 1017 children with fever and/or fast/difficult breathing and performed 975 RDTs. Malaria and/or pneumonia were appropriately classified 94-100% of the time. Treatment based on disease classification was correct in 94-100% of episodes. Supply management was excellent with over 98% of RDTs, amoxicillin, and AL properly accounted for. The use of RDTs, amoxicillin, and AL was associated with few minor adverse events. Most febrile children (90%) with negative RDT results recovered after being treated with an antipyretic alone. Volunteer CHWs in rural Zambia are capable of providing integrated management of malaria and pneumonia to children safely and at high quality.

    2014-01-01

    Full Text Available Background. Acetaminophen (APAP is a commonly used analgesic and antipyretic. When administered in high doses, APAP is a clinical problem in the US and Europe, often resulting in severe liver injury and potentially acute liver failure. Studies have demonstrated that antioxidants and anti-inflammatory agents effectively protect against the acute hepatotoxicity induced by APAP overdose. Methods. The present study attempted to investigate the protective effect of B. trimera against APAP-induced hepatic damage in rats. The liver-function markers ALT and AST, biomarkers of oxidative stress, antioxidant parameters, and histopathological changes were examined. Results. The pretreatment with B. trimera attenuated serum activities of ALT and AST that were enhanced by administration of APAP. Furthermore, pretreatment with the extract decreases the activity of the enzyme SOD and increases the activity of catalase and the concentration of total glutathione. Histopathological analysis confirmed the alleviation of liver damage and reduced lesions caused by APAP. Conclusions. The hepatoprotective action of B. trimera extract may rely on its effect on reducing the oxidative stress caused by APAP-induced hepatic damage in a rat model. General Significance. These results make the extract of B. trimera a potential candidate drug capable of protecting the liver against damage caused by APAP overdose.

    The rhizomes of Cimicifuga species, including Cimicifuga heracleifolia (CH), have been widely used as antipyretic, analgesic, and anti-inflammatory agents in oriental countries. However, information regarding its toxicity, especially long-term toxicity and genotoxicity, is limited. Therefore, we performed the subchronic toxicity and genotoxicity assays of the CH extract in accordance with the test guidelines published by the Organization for Economic Cooperation and Development. In a 13-week repeat-dose oral toxicity study, the CH extract did not influence body weight, food/water consumption, mortality, clinical signs, and urinalysis throughout the study. Noteworthy, the CH extract groups exhibited increased liver weights along with serum alanine transaminase activity rise at doses of 667 and 2000 mg/kg in females. No-observed-adverse-effect-level of the CH extract administered orally was concluded to be 2000 mg/kg body weight/day for male rats and 222 mg/kg body weight/day for female rats. The CH extract did not exert a mutagenic or clastogenic effect in Ames test, in vitro chromosome aberration assay and in vivo micronucleus assay. Overall findings of the subchronic toxicity study indicate for the first time that the CH extract may possess hepatotoxic potential in female rats, suggesting that further mechanistic studies should be performed to have more conclusive results on hepatotoxic potential of the CH extract.

    Cimicifugoside, a triterpenoid isolated from Cimicifuga simplex, which has been used as a traditional Chinese medicine due to its anti-inflammatory, analgesic or anti-pyretic action, was examined for inhibition of nucleoside transport and synergistic potentiation of methotrexate cytotoxicity. Cimicifugoside inhibited uptake of uridine, thymidine and adenosine in human leukemia U937 cells with the low nanomolar IC(50) values, but did not affect that of uracil, leucine or 2-deoxyglucose at cimicifugenin (aglycon of cimicifugoside)>bugbanoside B>cimicifugenin A, O-methyl cimicifugenin and bugbanoside A. Cimicifugoside had less affinity for the binding site of nitrobenzylthioinosine (typical high-affinity inhibitor of equilibrative nucleoside transporter-1) in U937 cells, K562 cells and human erythrocyte membranes compared with the prototype nucleoside transport inhibitor dipyridamole. Cimicifugoside markedly potentiated methotrexate cytotoxicity in a culture of U937 cells and human carcinoma KB cells. Potentiation of methotrexate cytotoxicity by cimicifugoside analogs in U937 cells was in proportion to their inhibitory activity against uridine uptake. The present study demonstrates that cimicifugoside is a novel specific nucleoside transport inhibitor that displays synergistic potentiation of methotrexate cytotoxicity.

    Rhizoma Anemarrhenae , a famous traditional Chinese medicine (TCM), is the dried rhizome of Anemarrhena asphodeloides Bge. ( Anemarrhena Bunge of Liliaceae). The medicine presents anti-inflammatory, antipyretic, sedative, and diuretic effects. The chemical constituents of Rhizoma Anemarrhenae are complex and diverse, mainly including steroidal saponins, flavonoids, phenylpropanoids, benzophenones, and alkaloids. In this study, UPLC-Q-TOF/MS was used in combination with data postprocessing techniques, including characteristic fragments filter and neutral loss filter, to rapidly classify and identify the five types of substances in Rhizoma Anemarrhenae . On the basis of numerous literature reviews and according to the corresponding characteristic fragments produced by different types of compounds in combination with neutral loss filtering, we summarized the fragmentation patterns of the main five types of compounds and successfully screened and identified 32 chemical constituents in Rhizoma Anemarrhenae . The components included 18 steroidal saponins, 6 flavonoids, 4 phenylpropanoids, 2 alkaloids, and 2 benzophenones. The method established in this study provided necessary data for the study on the pharmacological effects of Rhizoma Anemarrhenae and also provided the basis for the chemical analysis and quality control of TCMs to promote the development of a method for chemical research on TCMs.

    Congenital heart disease (CHD) is the most common birth defect. It is due to dysfunction of the heart and great vessels during embryo development stage, or the channel was not closed after birth. This study focuses on investigating the influence of virus infection and medicine history during pregnancy on the incidence rate of CHD of fetus. We conducted a retrospective birth cohort study of infant born in the maternal and child health hospital of Fanyu district in Guangzhou. Five thousand three hundred eighty one cases with complete medical records, including mothers, fathers, and infants, were enrolled. The exposure history of mothers to virus and medicine from 6 months before pregnancy to prenatal examination was investigated, including mflu, mumps, measles, rubella, chickenpox, and hepatitis and antibiotics, tocolytic agent, anticonvulsants, antipyretic and analgesic, antitumor drug, folic acid supplement, and contraceptive. The relationship between virus infection and medicine history during pregnancy and CHD was analyzed. There was statistical difference between a normal group and a defected group in influenza infection and tocolytic agent and contraceptive pill. The exposure history to influenza and medicines, such as tocolytic agent and contraceptive pill, during pregnancy influenced the incidence rate of CHD of fetus.

    I. viscosa has been used for years in folk medicine for its anti-inflammatory, antipyretic, antiseptic, and paper antiphlogistic activities. In this study, cytotoxic and genotoxic effects of I. viscosa leaf extracts on the root meristem cells of Allium cepa have been examined. Onion bulbs were exposed to 2.5 mg/ml, 5 mg/ml, and 10 mg/ml concentrations of the extracts for macroscopic and microscopic analysis. Tap water has been used as a negative control and Ethyl methanesulfonate (EMS) (2 · 10−2 M) has been used as a positive control. The test concentrations have been determined according to doses which are recommended for use in alternative medicine. There has been statistically significant (P < .05) inhibition of root growth depending on concentration by the extracts when compared with the control groups. All the tested extracts have been observed to have cytotoxic effects on cell division in A. cepa. I. viscosa leaf extract induces the total number of chromosomal aberrations and micronuclei (MNC) formations in A. cepa root tip cells significantly when compared with control groups. Also, this paper shows for the first time the induction of cell death, ghost cells, cells with membrane damage, and binucleated cells by extract treatment. These results suggest the cytotoxic and genotoxic effects of the I. viscosa leaf extracts on A. cepa. PMID:20617136

    To evaluate the cerebral and hemodynamic effects of low-dose intramuscular diclofenac sodium (DCFS) administered for fever control in patients with acute brain injury in the intensive care unit. Inclusion criteria for this prospective clinical study were age ≥18 years; the ability to monitor intra-arterial blood pressure, core body temperature, and intracranial pressure; the placement of an indwelling jugular venous catheter for intermittent jugular venous oxygen saturation measurements; and a core body temperature ≥37.5°C. Exclusion criteria were hypovolemia, administration of drugs with hemodynamic effects during the study period, administration of antipyretics within 6 hours before the start of the study, acute heart failure, cerebral vasospasm, pregnancy, renal and gastric diseases, and allergy to DCFS. The study enrolled 30 patients with acute brain injury. Two We observed statistically significant decreases in core body temperature (P administration with respect to baseline (T0). The dosage of noradrenaline (norepinephrine) in subjects receiving treatment at the start of the study increased significantly from 0.14 μg/kg/minute ± 0.1 to 0.20 μg/kg/minute ± 0.1 (P = 0.0395). Low-dose intramuscular DCFS administration for fever control in patients with acute brain injury is effective but also exposes patients to potentially deleterious hypotensive episodes that must be diagnosed and treated expeditiously to prevent further damage to the injured brain.

    Paracetamol (acetaminophen) is an analgesic and antipyretic drug widely used across the world. Its ingestion is one of the most common causes of drug overdose. In the United States is the first cause of acute hepatitis in adults. To describe the epidemiological profile of paracetamol overdose in Chile. Cross sectional retrospective study that included all the phone call inquiries received at the Poison Control Center of the Pontificia Universidad Catolica de Chile (CITUC) during 2009. Nine hundred fifty nine inquiries involving acute paracetamol exposures were received. Women represented a 63.1% of the cases. Half of the cases were suicide attempts, of which 74.8% were women. Accidental exposures occurred mainly in children. In 29.3% of the patients, the exposure was considered to involve a hepatotoxic dose. Women had 2.7 times the risk of men to ingest a toxic dose of paracetamol with suicidal purpose (Odds ratio (OR) = 2.7; 95% confidence interval (Cl): 2.1-3.6; p Paracetamol overdose is common in Chile. Authorities should carry out preventive measures. Antidotes and the capacity to measure plasma levels of paracetamol should be available in healthcare centers.

    Paracetamol is one of the most commonly used analgesics and antipyretics available without limits as preparations of the OTC group (over the counter drugs). Overdose and poisoning with this drug always brings about the risk of acute hepatic failure. The objective of the study was a retrospective evaluation of patients hospitalized in the Paediatric Clinic during the period 2004-2012 due to poisoning with paracetamol. The analysis covered 44 patients hospitalized in the Paediatric Clinic during 2004-2012 due to poisoning with paracetamol. Patients were divided into three groups: intentional poisonings, accidental poisonings, and drug overdose. During the period of the study, 44 patients aged 2.1-17.1, poisoned with paracetamol, were hospitalized. Among these patients there were 30 (68.2%) cases of intentional poisonings, 10 (22.7%) of accidental poisonings, and only 4 patients (9.1%) were children hospitalized after a paracetamol overdose. The majority of patients in all groups were females (93.3%). Paracetamol intoxication may occur after exceeding a single allowable dose, in the case of intentional poisoning, more rarely after exceeding the daily dose, in the case of intense pain complaints, or in the treatment of persistent fever. Based on the analysis performed, an increase was observed in the frequency of poisoning with paracetamol, especially intentional poisoning. Unlimited access to paracetamol as an OTC drug should be reconsidered.

In the group that used medicines without medical prescription, the drugs used most often were analgesics (30% and antipyretics (29%. Of the reasons presented to justify the use of self-prescribed medicines, pain was the most frequent one (38.3%, followed by fever (24.4%, diarrhea (8.0%, hypertension (8.0% and cough (5.2%. There was association between the lack of exercise and self-medication (x² =14.44 p=0.001. CONCLUSIONS: there is a high prevalence of self-medication in this group; analgesics and antipyretics are the drugs used most often; pain is the symptom that most leads to self-medication; and sedentary individuals use more self-medication than those who exercise.

    Aescin (escin) derived from the seeds of horse chestnut (Aesculus hippocastanum L.) is a natural mixture of triterpene saponins exhibiting a wide variety of pharmacological properties, including antiinflammatory, analgesic, and antipyretic activities. However, data concerning antifungal activities of these compounds are limited. This study aims to evaluate the in vitro antifungal susceptibility of Candida glabrata clinical isolates to α-aescin sodium, β-aescin crystalline and β-aescin sodium using the disk diffusion (DD) and broth microdilution (BMD) methods. Moreover, the influence of subinhibitory concentration (0.5×MIC) of β-aescins on the nystatin MIC was also studied. In general, the results obtained by the DD assay correlated well with those obtained by the BMD method. Both β-aescins effectively inhibited the growth of all 24 strains tested. The minimum inhibitory concentration (MIC) values ranging from 8 to 32 μg/ml for β-aescin crystalline, whereas those of β-aescin sodium were slightly lower and ranged from 4 to 16 μg/ml. In contrast, α-aescin sodium was found to be completely ineffective against the strains studied. MIC values of nystatin were reduced 2-16-fold and 2-4-fold in the presence of subinhibitory concentration of β-aescin crystalline and β-aescin sodium, respectively. Results of the present study may suggest the additive interaction between β-aescin and nystatin. © The Author 2015.

    There is a concern that allergic disease in childhood is higher than expected in Cuba. The aim of this study was to determine the risk factors for eczema of infants aged 12-15 months living in Havana. We used a cross-sectional epidemiological study design. Data on eczema symptoms and a wide range of lifestyle factors were collected by researcher administered questionnaires. Data were collected on 1956 children (96% response rate), of whom 672 (34%) were reported as having had eczema. Independent risk factors for eczema included young maternal age (adjusted odds ratio (OR) 0.98 per additional year of age; 95% confidence interval (CI) 0.97-0.99), child's weight (OR 1.13 per additional kg; 95% CI: 1.03-1.25), insect sting allergy (OR 2.11; 95% CI: 1.33-3.35), rodents in the home (OR 1.39; 95% CI: 1.10-1.76), attendance at childcare facilities (OR 1.34: 95% CI: 1.05-1.70) and self-reported mould in the home (OR 1.23; 95% CI: 1.07-1.41). Infant exposure to paracetamol was associated with an increased risk of eczema even after adjustment for wheeze (OR 1.22; 95% CI: 1.03-1.46). Despite a very different culture and environment, the consistency of these findings with those from more economically developed countries suggests potential causal associations. The association with paracetamol, even after adjustment for wheeze, suggests that intervention studies are required in young infants, to ascertain if this commonly used anti-pyretic medication increases allergic disease.

    Loss-of-function sodium channelopathies manifest as a spectrum of diseases including Brugada syndrome (BrS) and cardiac conduction disease. To analyze the diagnostic and therapeutic aspects of these disorders in children. Patients aged ≤ 16 years with genetically confirmed loss-of-function sodium channelopathies (SCN5A mutation), presenting with cardiac symptoms, positive family history, and/or abnormal electrocardiogram (ECG), were included. Abnormal ECG consisted of type 1 BrS ECG and/or prolonged conduction intervals (PR interval/QRS duration > 98th percentile for age). Among the cohort (n = 33, age 6 ± 5 years, 58% male subjects, 30% probands), 14 (42%) patients were symptomatic, presenting with syncope (n = 5), palpitations (n = 1), supraventricular arrhythmias (n = 3), aborted cardiac arrest (n = 3), and sudden cardiac death (n = 2). Heart rate was 91 ± 26 beats/min, PR interval 168 ± 35 ms, QRS duration 112 ± 20 ms, and heart-rate corrected QT interval 409 ± 26 ms. Conduction intervals were prolonged in 28 (85%) patients; 6 of these patients also had spontaneous type 1 BrS ECG. Eight fever-associated events occurred in 6 patients; 2 of these were vaccination-related fever episodes. Treatment included aggressive antipyretics during fever in all patients; antiarrhythmic treatment included implantable cardioverter-defibrillator (n = 4), pacemaker (n = 2), and beta-blockers, either alone (n = 3) or in combination with device (n = 2). During follow-up (4 ± 4 years), 2 previously symptomatic patients had monomorphic ventricular tachycardia; there were no deaths. Diagnosis of loss-of-function sodium channelopathies in children relies on cardiac symptoms, family history, and ECG. Fever and vaccination are potential arrhythmia triggers; conduction delay is the commonest finding on ECG. Beta-blockers have a role in preventing tachycardia-induced arrhythmias; implantable cardioverter-defibrillator should probably be reserved for severe cases. Copyright © 2012

    Studies in the field of forensic pharmacology and toxicology would not be complete without some knowledge of the history of drug discovery, the various personalities involved, and the events leading to the development and introduction of new therapeutic agents. The first medicinal drugs came from natural sources and existed in the form of herbs, plants, roots, vines and fungi. Until the mid-nineteenth century nature's pharmaceuticals were all that were available to relieve man's pain and suffering. The first synthetic drug, chloral hydrate, was discovered in 1869 and introduced as a sedative-hypnotic; it is still available today in some countries. The first pharmaceutical companies were spin-offs from the textiles and synthetic dye industry and owe much to the rich source of organic chemicals derived from the distillation of coal (coal-tar). The first analgesics and antipyretics, exemplified by phenacetin and acetanilide, were simple chemical derivatives of aniline and p-nitrophenol, both of which were byproducts from coal-tar. An extract from the bark of the white willow tree had been used for centuries to treat various fevers and inflammation. The active principle in white willow, salicin or salicylic acid, had a bitter taste and irritated the gastric mucosa, but a simple chemical modification was much more palatable. This was acetylsalicylic acid, better known as Aspirin®, the first blockbuster drug. At the start of the twentieth century, the first of the barbiturate family of drugs entered the pharmacopoeia and the rest, as they say, is history. Copyright © 2011 John Wiley & Sons, Ltd.

    2011-01-01

    Background Entry screening tends to start with a search for febrile international passengers, and infrared thermoscanners have been employed for fever screening in Japan. We aimed to retrospectively assess the feasibility of detecting influenza cases based on fever screening as a sole measure. Methods Two datasets were collected at Narita International Airport during the 2009 pandemic. The first contained confirmed influenza cases (n = 16) whose diagnosis took place at the airport during the early stages of the pandemic, and the second contained a selected and suspected fraction of passengers (self-reported or detected by an infrared thermoscanner; n = 1,049) screened from September 2009 to January 2010. The sensitivity of fever (38.0°C) for detecting H1N1-2009 was estimated, and the diagnostic performances of the infrared thermoscanners in detecting hyperthermia at cut-off levels of 37.5°C, 38.0°C and 38.5°C were also estimated. Results The sensitivity of fever for detecting H1N1-2009 cases upon arrival was estimated to be 22.2% (95% confidence interval: 0, 55.6) among nine confirmed H1N1-2009 cases, and 55.6% of the H1N1-2009 cases were under antipyretic medications upon arrival. The sensitivity and specificity of the infrared thermoscanners in detecting hyperthermia ranged from 50.8-70.4% and 63.6-81.7%, respectively. The positive predictive value appeared to be as low as 37.3-68.0%. Conclusions The sensitivity of entry screening is a product of the sensitivity of fever for detecting influenza cases and the sensitivity of the infrared thermoscanners in detecting fever. Given the additional presence of confounding factors and unrestricted medications among passengers, reliance on fever alone is unlikely to be feasible as an entry screening measure. PMID:21539735

    Access to medicines without prescription is a major contributing factor for self-medication practices. This study was designed to examine the ratio of non-prescribed medicines sales and self-medication practices in Punjab, Pakistan. This study also evaluates the reasons for self-medication within its communities. An observational study was conducted in 272 systemically selected pharmacies to analyze medicines-related sales, with or without prescription. A cross-sectional survey was performed between June 2015 and November 2016. Consumers were interviewed about their self-medication practices. Of the pharmacies surveyed, 65.3% participated in the study. A total of 4348 medicines were purchased for self-medication by 3037 consumers (15.2% of all study participants), of which 873 (28.7%) participated in an interview. Majority (81.2%) medicine purchaser, (90.9%) interview participants, and (59.4%) drug users were male. On average, each community pharmacy sold 7.9 medicines without prescription each day, to an average of 5.5 customers. Many participants (28.9%) had matriculation in their formal education. The medicines most often sold for self-medication were analgesics and antipyretics(39.4%). More than 25% of participants reported fever symptoms and 47.8% assumed their illness was too trivial to consult a doctor. Media advertisements were the most common source of information for participants (46.7%). Many types of medicines were often sold without prescription from community pharmacies. Self-medication was common practice for a wide range of illnesses. Pakistan also needs effective implementation of policies to monitor medication sales. Public education about rational medication and limits to advertising medicine are very necessary.

    Full Text Available Abstract Background Fever is one of the most common childhood symptoms. It causes significant worry and concern for parents. Every year there are numerous cases of over- and under-dosing with antipyretics. Caregivers seek reassurance from a variety of sources including healthcare practitioners. The aim of this study was to describe parental knowledge, attitudes and beliefs regarding management of childhood fever in children aged 5 years and under. Method Semi-structured interviews were conducted with 23 parents at six ante-natal clinics in the south west of Ireland during March and April 2015. The Francis method was used to detect data saturation and thereby identify sample size. Thematic analysis was used to analyse the data. Results Twenty-three parents participated in the study. Five themes emerged from the data: assessing and managing the fever; parental knowledge and beliefs regarding fever; knowledge source; pharmaceutical products; initiatives. Parents illustrated a good knowledge of fever as a symptom. However, management practices varied between participants. Parents revealed a reluctance to use medication in the form of suppositories. There was a desire for more accessible, consistent information to be made available for use by parents when their child had a fever or febrile illness. Conclusion Parents indicated that further initiatives are required to provide trustworthy information on the management of fever and febrile illness in children. Healthcare professionals should play a significant role in educating parents in how to manage fever and febrile illnesses in their children. The accessible nature and location of pharmacies could provide useful support for both parents and General Practitioners.

    Most children with pain are managed by either acetaminophen or ibuprofen. However, no study has so far investigated if children are prescribed adequate doses of acetaminophen or ibuprofen in emergency department. Aim of this retrospective study was to investigate the prevalence of under-dosage of these drugs in children presenting with pain in emergency department. Children initially prescribed with acetaminophen or ibuprofen for pain management were included. The χ 2 automatic interaction detection method was used considering the percentage variation from the minimum of the appropriate dose as dependent variable while prescribed drug, age, gender, body weight, type of hospital (pediatric or general), and availability of internal guidelines on pediatric pain management in the emergency department as independent variables. Data on 1471 children managed for pain were available. Under-dosage was prescribed in 893 subjects (61%), of whom 577 were prescribed acetaminophen and 316 ibuprofen. The use of acetaminophen suppositories, body weight 40 kg, and the use of oral ibuprofen identified clusters of children associated with under-dosage prescription. Prescription of acetaminophen and ibuprofen was frequently under-dosed. The use of suppositories, lower and higher body weight, and the use of ibuprofen were associated with under-dosage. Under-dosing may reflect prescription of anti-pyretic doses. Agenzia Italiana del Farmaco-Observational Study Register (RSO). Registration code: PIERRE/1 What is Known: • Pain is frequent in children presented to emergency department. • International recommendations on pain management are often not implemented. What is New: • Acetaminophen and ibuprofen were frequently underdosed in children prescribed for pain in the Italian emergency departments. • Under-dosage may be related to the habit of using acetaminophen and ibuprofen in the recommended range for fever treatment.

    Artemisia arborescens, also known as tree wormwood, is a typical species of the Mediterranean flora. It has been used in folk medicine for its antispasmodic, anti-pyretic, anti-inflammatory, and abortifacient properties. In the current study, the application of multidimensional comprehensive gas chromatography (GC×GC), allowed to obtain a detailed fingerprint of the essential oil from A. arborescens aerial parts, highlighting an abundant presence of chamazulene followed by camphor, β-thujone, myrcene, and α-pinene. Moreover, flavonoids in the dichloromethane extract were analyzed by means of liquid chromatography with photodiode array and atmospheric pressure chemical ionization-mass spectrometry detections (HPLC-PDA and HPLC-APCI-MS). Six polymethoxyflavones were identified and three of them, including chrysosplenetin, eupatin, and cirsilineol, were described in this species for the first time. The anti-angiogenic activity was investigated in the dichloromethane extract by two in vivo models, chick chorioallantoic membrane (CAM) and zebrafish embryos. Results showed that this extract produced a strong reduction on vessel formation, both on zebrafish (57% of inhibition, 0.1 mg/mL) and chick chorioallantoic membrane (58% of inhibition, 0.8 mg/mL). The high separation power and sensitivity of the analytical methodology applied confirmed the safety of A. arborescens essential oil for human consumption, due to the very low level of the psychotrope α-thujone determined. Moreover, the knowledge of the flavonoidic profile holds a great significance for the use of A. arborescens as a valuable source of anti-angiogenic compounds that might contribute to the valorization of the phytotherapeutic potential of this plant.

    To determine the prevalence of self-medication and assess the knowledge, attitudes, and perception of consumers toward self-medication. This cross-sectional survey was conducted over 4 weeks in May 2011 in Riyadh city, Kingdom of Saudi Arabia. Community pharmacies within 5 areas of the city (North, South, West, East, and Middle) were randomly selected for the study. All consumers were approached to participate in the study, with the exception of those buying cosmetic and medicinal equipments. A validated self-administered questionnaire was used to collect the data. A total of 538 out of 707 consumers attending community pharmacies in Riyadh city, agreed to participate in the study. Most responders were male (73%), 23-33 years old (35%), and college graduates (42%). A total of 285 medications were bought without a prescription. Of these, 149 (49%) medications should be dispensed by prescription only, and 155 (51%) were over the counter medications. The most common prescription medications dispensed without prescriptions were antibiotics (22%) and analgesics/antipyretics (19%). The most common reasons for buying medications without a prescription were that the symptoms were too minor to visit a doctor (54%), time saving (40%), and minor illnesses for which the participants knew the required treatment (40%). Overall, most participants had poor knowledge, and negative perceptions regarding self-medication. More than 68% of participants did not know whether the medicine they bought is a prescription-only or over the counter medication. Irresponsible self-medication is common in Saudi Arabia. Future studies should focus on improving the consumers' awareness of self-medication and the proper use of medications.

Similar to other preventable health-risk behaviors initiated in early adolescence, it has become a cause for concern universally. This study examines the prevalence of self-medication with both prescribed and non-prescribed (OTC) medications, related health complaints, sources of drugs, and sources of drug recommendation, and gender differences related to self-medication among expatriate high school students in the United Arab Emirates (UAE). A cross-sectional survey was conducted among 324 expatriate students through a validated, self-administered questionnaire and data was analyzed using SPSS 19 version. Means and proportions were calculated and Pearson Chi-square test of significance was used to analyze association among variables. Majority of the participating students, almost equally distributed by gender, was aged 16 to 17 years. The period prevalence rate of self-medication with prescribed and OTC medications were 89.2%, which did not vary with age, gender, ethnicity or parents' educational level. The most common sources of drug and drug recommendation were community pharmacies and parents respectively. Headache and fever were the common self-medicated conditions and consequently, analgesics and antipyretics were most commonly used both in the previous two weeks and the previous year prior to the survey. A high prevalence of self-medication with antibiotics (53%) and sedative/hypnotics (27%) was also observed. A female excess emerged for certain health complaints and use of medicines except for the use of anti-allergic and herbal/homeopathic drugs. This is the first study to explore self-medication practices among high school students in UAE and provides baseline data critical in creating awareness about the risks and benefits of self-medication. Health care providers, educators and parents should be actively involved in health education strategies

    Objectives: To determine the prevalence of self-medication and assess the knowledge, attitudes, and perception of consumers toward self-medication. Methods: This cross-sectional survey was conducted over 4 weeks in May 2011 in Riyadh city, Kingdom of Saudi Arabia. Community pharmacies within 5 areas of the city (North, South, West, East, and Middle) were randomly selected for the study. All consumers were approached to participate in the study, with the exception of those buying cosmetic and medicinal equipments. A validated self-administered questionnaire was used to collect the data. Results: A total of 538 out of 707 consumers attending community pharmacies in Riyadh city, agreed to participate in the study. Most responders were male (73%), 23-33 years old (35%), and college graduates (42%). A total of 285 medications were bought without a prescription. Of these, 149 (49%) medications should be dispensed by prescription only, and 155 (51%) were over the counter medications. The most common prescription medications dispensed without prescriptions were antibiotics (22%) and analgesics/antipyretics (19%). The most common reasons for buying medications without a prescription were that the symptoms were too minor to visit a doctor (54%), time saving (40%), and minor illnesses for which the participants knew the required treatment (40%). Overall, most participants had poor knowledge, and negative perceptions regarding self-medication. More than 68% of participants did not know whether the medicine they bought is a prescription-only or over the counter medication. Conclusion: Irresponsible self-medication is common in Saudi Arabia. Future studies should focus on improving the consumers’ awareness of self-medication and the proper use of medications. PMID:25737176

    The rate of severe cutaneous adverse drug reactions is low, and these reactions can result in death or disability. An evidence-based epidemiological study of severe cutaneous adverse drug reactions in China has not been reported. The aim of this study was to analyze epidemiology and characteristics of severe cutaneous adverse drug reactions of Chinese inpatients during the recent 15 years with meta-analysis. We retrospectively reviewed Chinese literature reporting severe cutaneous adverse drug reactions and collecting data from 2000 to 2015, which were in accordance with our inclusion criteria. All included data were analyzed with the Launch Open Meta-Analyst software. Twenty-five articles involving 928 cases with severe cutaneous adverse drug reactions were included. Men to women ratio was 1.14:1. Twenty-one per cent of the patients had drug allergy history. Antibiotics (26.0%), sedative hypnotics and anticonvulsants (21.6%), and antipyretic analgesics (17.1%) were the most common causative drugs. The most frequent clinical subtype was Stevens-Johnson syndrome (50.1%), followed by toxic epidermal necrolysis (25.4%), exfoliative dermatitis (21.0%) and drug-induced hypersensitivity syndrome (1.6%). In addition to skin rashes, patients with severe cutaneous adverse drug reactions suffered mostly from fever (73%), and blood routine abnormality (66.7%). This meta-analysis is limited by its retrospective design and by its methodological variation. The most common causative drugs were antibiotics and sedative hypnotics and anticonvulsants. Stevens-Johnson syndrome was the most frequent clinical subtype of severe cutaneous adverse drug reactions. In addition to skin rashes, patients with severe cutaneous adverse drug reactions suffered mostly from fever, mucosal lesion, and hematologic abnormalities.

    Full Text Available Rhinosinusitis is a very common condition of the upper respiratory tract. The disease may be caused by viral, bacterial or fungal infections as well as by allergens or air pollution (e.g. tobacco smoke, with viral infections being the most common cause. The first phase of viral rhinosinusitis therapy involves the use of antipyretics, analgesics, anti-oedematous agents as well as nasal decongestants, occasionally, topical glucocorticosteroids, nasal irrigation and adjunct phytotherapy. Viral or allergic rhinosinusitis does not require antibiotic therapy. Antibiotics should be used if symptoms persist after 7–10 days or bacterial superinfection develops. More intense treatment (antibiotic, metronidazole, intranasal glucocorticosteroid as well as formulations that dilute mucous secretions and have anti-oedematous effects for up to several days is necessary in cases of acute rhinosinusitis in children, which is quite often a very serious disease bordering on sepsis (pansinusitis. According to the 2012 European Position Paper on Rhinosinusitis and Nasal Polyps 2012 (EPOS 2012, natural compounds may be used as an adjunct treatment in some cases and in certain periods of the disease. These include nasal irrigation with saline or an appropriate seawater solution as well as the use of herbal medicinal products. The paper discusses in detail the use of different herbal medicinal products and presents literature data related to the efficacy and tolerance of these products.

    Full Text Available Introduction & Objective: Fever is very common in children and is usually due to self-limiting viral infections. Management of fever is based on culture, community and religion of people all over the world. Parental concerns arise in part because of the belief that fever is a disease rather than a symptom or sign of illness. Misconceptions about childhood fevers heighten parents' concerns leading to inappropriate use of antipyretic drugs or overdosing may cause drug toxicity and frequent use of health care services. This study aimed to identify parental views of fever management in their children aged 0-5 yr.Materials & Methods: In this cross sectional study, 350 parents with children less than 5 years referred to various units of clinics covered by community oriented center of Kermanshah, completed the research questionnaire. Validity and reliability of the questionnaire were determined and the data was analyzed by SPSS Software.Results: Findings showed that the first medical care was sponging (53.1%. Sponging with saltwater was common (47.7% and Over - the - counter medications were (30%. Acetaminophen was the first drug in 90% of the cases. However, many parents express high levels of anxiety so that they seek for self-medication with antibiotic 34% of the cases. Our study showed that correlation between over concern about fever management and parents who had a positive past medical history in their children with P=0.02, parents education (P=0.018 and in employed mothers (P=0.005 was statistically significant.Conclusion: Considerable efforts will be required to educate parents about fever and its management.(Sci J Hamadan Univ Med Sci 2012;19(2:28-33

    Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) that exhibits anti-inflammatory, antinociceptive, and antipyretic activities. Liposomes have been shown to improve the therapeutic efficacy of encapsulated drugs. The present study was conducted to compare the antinociceptive properties between liposome-encapsulated and free-form diclofenac in vivo via different nociceptive assay models. Liposome-encapsulated diclofenac was prepared using the commercialized proliposome method. Antinociceptive effects of liposome-encapsulated and free-form diclofenac were evaluated using formalin test, acetic acid-induced abdominal writhing test, Randall-Selitto paw pressure test, and plantar test. The results of the writhing test showed a significant reduction of abdominal constriction in all treatment groups in a dose-dependent manner. The 20 mg/kg liposome-encapsulated diclofenac demonstrated the highest antinociceptive effect at 78.97% compared with 55.89% in the free-form group at equivalent dosage. Both liposome-encapsulated and free-form diclofenac produced significant results in the late phase of formalin assay at a dose of 20 mg/kg, with antinociception percentages of 78.84% and 60.71%, respectively. Significant results of antinociception were also observed in both hyperalgesia assays. For Randall-Sellito assay, the highest antinociception effect of 71.38% was achieved with 20 mg/kg liposome-encapsulated diclofenac, while the lowest antinociceptive effect of 17.32% was recorded with 0 mg/kg liposome formulation, whereas in the plantar test, the highest antinociceptive effect was achieved at 56.7% with 20 mg/kg liposome-encapsulated diclofenac, and the lowest effect was shown with 0 mg/kg liposome formulation of 8.89%. The present study suggests that liposome-encapsulated diclofenac exhibits higher antinociceptive efficacy in a dose-dependent manner in comparison with free-form diclofenac.

  14. Diclofenac: an update on its mechanism of action and safety profile.

    Diclofenac is a proven, commonly prescribed nonsteroidal anti-inflammatory drug (NSAID) that has analgesic, anti-inflammatory, and antipyretic properties, and has been shown to be effective in treating a variety of acute and chronic pain and inflammatory conditions. As with all NSAIDs, diclofenac exerts its action via inhibition of prostaglandin synthesis by inhibiting cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) with relative equipotency. However, extensive research shows the pharmacologic activity of diclofenac goes beyond COX inhibition, and includes multimodal and, in some instances, novel mechanisms of action (MOA). Literature retrieval was performed through PubMed/MEDLINE (through May 2009) using combinations of the terms diclofenac, NSAID, mechanism of action, COX-1, COX-2, and pharmacology. Reference citations resulting from publications identified in the literature search were reviewed when appropriate. This article reviews the established, putative, and emerging MOAs of diclofenac; compares the drug's pharmacologic and pharmacodynamic properties with other NSAIDs to delineate its potentially unique qualities; hypothesizes why it has been chosen for further recent formulation enhancement; and evaluates the potential effect of its MOA characteristics on safety. Research suggests diclofenac can inhibit the thromboxane-prostanoid receptor, affect arachidonic acid release and uptake, inhibit lipoxygenase enzymes, and activate the nitric oxide-cGMP antinociceptive pathway. Other novel MOAs may include the inhibition of substrate P, inhibition of peroxisome proliferator activated receptor gamma (PPARgamma), blockage of acid-sensing ion channels, alteration of interleukin-6 production, and inhibition of N-methyl-D-aspartate (NMDA) receptor hyperalgesia. The review was not designed to compare MOAs of diclofenac with other NSAIDs. Additionally, as the highlighted putative and emerging MOAs do not have clinical data to demonstrate that these models are

    Acetylsalicylic acid (aspirin) is one of the most widely used drugs worldwide, due mainly to its broad therapeutic spectrum with anti-inflammatory, antipyretic, antithrombotic and analgesic effects. However, the exact mechanisms by which aspirin influences inflammation, pain and immune system activation are only partly understood. Within activation of the cellular immune system, Th1-type cytokine interferon (IFN)-gamma induces enzyme indoleamine-2,3-dioxygenase (IDO) which converts tryptophan to kynurenine. In parallel, IFN-gamma induces enzyme GTP-cyclohydrolase I, which gives rise to neopterin production by activated human macrophages. Similarly, tryptophan degradation and neopterin formation increase during several disease states involving Th1-type immune activation. Using stimulated human peripheral blood mononuclear cells (PBMC), the effect of aspirin on tryptophan degradation and neopterin production was investigated. Stimulation of PBMC with mitogens concanavalin A, phytohaemagglutinin and pokeweed mitogen induced significant tryptophan catabolism as was reflected by a decline in tryptophan levels and a parallel increase in kynurenine concentrations compared with unstimulated cells. In parallel, neopterin production was enhanced. Treatment of stimulated PBMC with increasing doses of 1-5 mM aspirin significantly decreased stimulation-induced tryptophan degradation and neopterin production as well. All the effects of aspirin were dose-dependent. The parallel influence of aspirin on both biochemical pathways implies that there was no direct inhibitory effect of aspirin on IDO; rather, it inhibits production of IFN-gamma in mitogen-treated PBMC. The influence of aspirin on biochemical pathways induced by IFN-gamma may represent an important part of its broad pharmacological effect.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most commonly used drugs in the world due to their anti-inflammatory, analgesic and antipyretic properties. Nevertheless, the consumption of these drugs is still associated with the occurrence of a wide spectrum of adverse effects. Regarding the major role of membranes in cellular events, the hypothesis that the biological actions of NSAIDs may be related to their effect at the membrane level has triggered the in vitro assessment of NSAIDs-membrane interactions. The use of membrane mimetic models, cell cultures, a wide range of experimental techniques and molecular dynamics simulations has been providing significant information about drugs partition and location within membranes and also about their effect on diverse membrane properties. These studies have indeed been providing evidences that the effect of NSAIDs at membrane level may be an additional mechanism of action and toxicity of NSAIDs. In fact, the pharmacokinetic properties of NSAIDs are closely related to the ability of these drugs to interact and overcome biological membranes. Moreover, the therapeutic actions of NSAIDs may also result from the indirect inhibition of cyclooxygenase due to the disturbing effect of NSAIDs on membrane properties. Furthermore, increasing evidences suggest that the disordering effects of these drugs on membranes may be in the basis of the NSAIDs-induced toxicity in diverse organ systems. Overall, the study of NSAIDs-membrane interactions has proved to be not only important for the better understanding of their pharmacological actions, but also for the rational development of new approaches to overcome NSAIDs adverse effects.

    Non-steroidal anti-inflammatory drugs (NSAIDs) display anti-inflammatory, antipyretic and analgesic properties by inhibiting cyclooxygenases and blocking prostaglandin production. Previous studies, however, suggested that some NSAIDs also modulate peroxisome proliferator activated receptors (PPARs), raising the possibility that such off target effects contribute to the spectrum of clinically relevant NSAID actions. In this study, we set out to understand how peroxisome proliferator activated receptor-γ (PPARγ/PPARG) interacts with NSAIDs using X-ray crystallography and to relate ligand binding modes to effects on receptor activity. We find that several NSAIDs (sulindac sulfide, diclofenac, indomethacin and ibuprofen) bind PPARγ and modulate PPARγ activity at pharmacologically relevant concentrations. Diclofenac acts as a partial agonist and binds to the PPARγ ligand binding pocket (LBP) in typical partial agonist mode, near the β-sheets and helix 3. By contrast, two copies of indomethacin and sulindac sulfide bind the LBP and, in aggregate, these ligands engage in LBP contacts that resemble agonists. Accordingly, both compounds, and ibuprofen, act as strong partial agonists. Assessment of NSAID activities in PPARγ-dependent 3T3-L1 cells reveals that NSAIDs display adipogenic activities and exclusively regulate PPARγ-dependent target genes in a manner that is consistent with their observed binding modes. Further, PPARγ knockdown eliminates indomethacin activities at selected endogenous genes, confirming receptor-dependence of observed effects. We propose that it is important to consider how individual NSAIDs interact with PPARγ to understand their activities, and that it will be interesting to determine whether high dose NSAID therapies result in PPAR activation.

    The occurrences of pharmaceuticals and personal care products as emerging organic contaminants (EOCs) have been reported in several countries of the world except from African countries. This study was therefore conducted to investigate the occurrence of nine antibiotics, five antipyretics, atenolol, bezafibrate, and caffeine in wastewater and surface water samples from the Umgeni River. The water samples were extracted with solid-phase extraction using hydrophilic-lipophilic balance (HLB) and C-18 cartridges for the acidic and neutral drugs, respectively. The quantification was carried out with high-performance liquid chromatography-diode array detector (HPLC-DAD) using the standard addition method. The method limits of detections were in the range of 0.14-0.97 μg/L while the recoveries were between 53.8 and 108.1 %. The wastewater had 100 % occurrence of the analytes studied, with caffeine having the highest concentration at 61 ± 5 μg/L and nalidixic acid being the most observed antibiotic at 31 ± 3 μg/L. The waste treatment process reduced the influent concentrations by 43.0-94.2 % before discharge except for atenolol removal that is lower. The concentrations of the analytes were lower in the surface water with most compounds having concentrations below 10 μg/L except acetaminophen and atenolol. The estuary mouth and Blue Lagoon had the highest concentrations of some of the compounds in surface water which depict downstream load. The factors governing the fate and mobility of these compounds in this environment are not fully understood yet and will require further studies.

    The plethora of ethnomedicinal applications of Tamarindus indica Linn. (Leguminosae), tamarind, includes treatment of human and livestock ailments; preparations are recognized antipyretics in fevers, laxatives and carminatives. African folklore has various applications of tamarind. However, in Nyasaland, domestic fowl are fed with preparations for prophylactic properties. The objective of this study is to evaluate the antiviral properties of T. indica extract. Tamarindus indica stem bark was extracted through ethanol maceration over 24 h, and the crude extract was fractionated by gravity-propelled column chromatography. Newcastle disease virus (NDV) inhibitory activity of extract and fractions were evaluated in vivo using 10-d-old embryonated chicken egg (ECE) as the medium for virus cultivation and antivirus assay. About 240 ECE were grouped into eight (three controls and five experimental) and, 200 μL of the extract and fractions respectively inoculated into NDV pre-infected eggs and incubated at 37 °C. Allantoic fluid was harvested 5 d post-virus infection and assayed for haemagglutination (HA). Anti-NDV assessment showed 62.5 mg/mL of crude extract and fractions: TiA, TiC and TiD to yield a HA titre of 1:128 each, while TiB showed 1:64 HA titre. At 125 mg/mL, a titre of 1:16 was recorded against TiB and TiD and, 1:8 against TiA. Similarly, crude extract and TiC, each recorded 1:4 HA titre. However, the minimum concentrations of extract and fraction for virus inactivation were 0.24 mg/mL and 0.49 mg/mL, respectively. The antiviral activity shown by T. indica portends novel antiviral drugs and, perhaps, as scaffold for new drugs.

Although four Plasmodium species, ie, Plasmodium (P. falciparum, P. vivax, P. malariae, and P. ovale, cause malaria in Mauritania, recent data on their frequency is ­lacking. Since infections with P. falciparum generally result in serious disease, their identification is important. We report a case of oliguric renal injury associated with malaria in a 65-year-old shepherd. Clinical manifestations included anemia, oliguria, and elevated creatinine and urea. The rapid diagnostic test for malaria and microscopic examination of blood smears were positive for P. falciparum. On the basis of this, the patient was diagnosed as having acute kidney injury as a complication of severe malaria. The patient was treated for malaria with intravenous quinine for 4 days, followed by 3 days of oral treatment. Volume expansion, antipyretic treatment, and diuretics were administered. He also had two rounds of dialysis after which he partially recovered renal function. This outcome is not always the rule. Prognosis depends much on early diagnosis and appropriate supportive treatment. Keywords: malaria, oliguric kidney injury, shepherd, quinine, dialysis

    The effect of a weight-based prescribing method within the electronic health record (EHR) on the rate of prescribing errors was studied. A report was generated listing all patients who received a prescription by a clinic provider for either infants' or children's acetaminophen or ibuprofen from January 1 to July 28, 2005 (preintervention group) and from July 29 to December 30, 2005 (postintervention group). Patients were included if they were 12 years old or younger, had a prescription ordered for infants' or children's acetaminophen or ibuprofen within the EHR, and had a weight documented in the chart on the visit day. The dosing range for acetaminophen was 10-15 mg/kg every four to six hours as needed, and the regimen for ibuprofen was 5-10 mg/kg every six to eight hours as needed. Dosing errors were defined as overdosage of strength, overdosage of regimen, underdosage of strength, under-dosage of regimen, and incomprehensible dosing directions. Totals of 316 and 224 patient visits were analyzed from the preintervention and postintervention groups, respectively. Significantly more medication errors were found in the preintervention group than in the postintervention group (103 versus 46, p = 0.002). Significantly fewer strength overdosing errors occurred in the postintervention group (8.9% versus 4.0%, p = 0.028). An automated weight-based dosing calculator integrated into an EHR system in the outpatient setting significantly reduced medication prescribing errors for antipyretics prescribed to pediatric patients. This effect appeared to be strongest for reducing overdose errors.

    Full Text Available Pracparatum mungo (Lu-Do Huang is a traditional Chinese functional medicine made from the natural fermentation of mung bean (綠豆 Lǜ Dòu mixed with other Chinese medicines. It has been recognized as having liver protecting and detoxifying effects. As mung beans have been verified to possess anti-inflammatory, antioxidant, antipyretic, and whitening actions, the present research utilized the in vitro, ex vivo, and in vivo experimental models to investigate the antioxidant and melanin inhibiting effects of P. mungo on the skin. The in vitro experiment revealed that P. mungo methanol extract (PMME and P. mungo ethanol extract (PMEE possess the capacity to clear α,α-diphenyl-2-picrylhydrazyl (DPPH radicals and inhibit tyrosinase activity. The ex vivo experiment indicated that PMEE can promote the growth of MDCK cells and increase the enzymatic activities of superoxide dismutase (SOD and catalase in MDCK cells. On the other hand, PMME and PMEE can suppress the proliferation of A375 cells, and PMEE can reduce the enzymatic activities of SOD and catalase in A375 cells. The in vivo results showed that P. mungo can enhance the enzymatic performance of SOD, Catalase, and glutathione peroxidase (GPx in the liver. The results also showed that P. mungo has antioxidant characteristics and can inhibit tyrosinase activity, thereby promoting the growth of skin tissues and suppressing the proliferation of A375 cells, and thus enhancing the effects that the antioxidant enzymatic performance has on the liver. These results can be applied in the development of tyrosinase inhibitors or antioxidants used for the inhibition of melanin biosynthesis or for auto-oxidation in further industrial applications, particularly those relating to functional food or cosmetic compositions.

    1. This manuscript presents the preclinical profile of lumiracoxib, a novel cyclooxygenase-2 (COX-2) selective inhibitor. 2. Lumiracoxib inhibited purified COX-1 and COX-2 with K(i) values of 3 and 0.06 microM, respectively. In cellular assays, lumiracoxib had an IC(50) of 0.14 microM in COX-2-expressing dermal fibroblasts, but caused no inhibition of COX-1 at concentrations up to 30 microM (HEK 293 cells transfected with human COX-1). 3. In a human whole blood assay, IC(50) values for lumiracoxib were 0.13 microM for COX-2 and 67 microM for COX-1 (COX-1/COX-2 selectivity ratio 515). 4. Lumiracoxib was rapidly absorbed following oral administration in rats with peak plasma levels being reached between 0.5 and 1 h. 5. Ex vivo, lumiracoxib inhibited COX-1-derived thromboxane B(2) (TxB(2)) generation with an ID(50) of 33 mg kg(-1), whereas COX-2-derived production of prostaglandin E(2) (PGE(2)) in the lipopolysaccharide-stimulated rat air pouch was inhibited with an ID(50) value of 0.24 mg kg(-1). 6. Efficacy of lumiracoxib in rat models of hyperalgesia, oedema, pyresis and arthritis was dose-dependent and similar to diclofenac. However, consistent with its low COX-1 inhibitory activity, lumiracoxib at a dose of 100 mg kg(-1) orally caused no ulcers and was significantly less ulcerogenic than diclofenac (P<0.05). 7. Lumiracoxib is a highly selective COX-2 inhibitor with anti-inflammatory, analgesic and antipyretic activities comparable with diclofenac, the reference NSAID, but with much improved gastrointestinal safety.

    To analyze and characterize the intake profile of pain-relief drugs in a population-based study of adults with chronic low back pain (CLBP). EpiReumaPt was a cross-sectional Portuguese population-based study (10,661 subjects). Self-reported active CLBP was considered to be low back pain on the day of enrollment and for ≥ 90 days. Prevalence and profile of analgesic intake was characterized among those self-reporting active CLBP, taking into account the intensity of pain and the World Health Organization (WHO) analgesic ladder. We further investigated whether the presence of active CLBP was a factor independently associated with the intake of analgesics (adjusted for potential confounders). Among 1,487 subjects with active CLBP, only 18.7% were using analgesic/pain-relief drugs. Estimated prevalence was anxiolytics, 14.1%; nonsteroidal anti-inflammatory drugs (NSAIDs), 12.3%; antidepressants, 10.1%; analgesic, antipyretics, 6.6%; anticonvulsants, 3.4%; central muscle relaxants, 2.6%; and analgesic opioids, 1.6%. Most subjects with severe pain were in the first step of the WHO analgesic ladder: NSAIDs plus anxiolytics (4.6%), NSAIDs plus antidepressants (3.2%), or NSAIDs plus muscle relaxants (2.5%). The presence of active CLBP was significantly associated with the intake of all therapeutic groups: antidepressants (odds ratio [OR] = 12.56; P pain-relief drug intake in patients with active CLBP was very low, even for those with severe pain. The WHO analgesic ladder was carefully followed, with an extremely conservative use of analgesic opioids even for those with severe pain. © 2016 World Institute of Pain.

    Wastewater samples from the secondary clarifier of two treatment plants were spiked in the microgram-to-tens-of-microgram per liter range with diuron (herbicide), ibuprofen and diclofenac (anti-inflammatory drugs), sulfamethoxazole and erythromycin (antibiotics), bezafibrate and gemfibrozil (lipid regulators), atenolol (β-blocker), carbamazepine (anti-epileptic), hydrochlorothiazide (diuretic), caffeine (stimulant) and N-acetyl-4-amino-antipiryne, a metabolite of the antipyretic drug dypirone. They were subsequently ozonated in continuous flow using 1.2L lab-scale bubble columns. The concentration of all spiking compounds was monitored in the outlet stream. The effects of varying ozone input, expressed as energy per unit volume, and water flow rate, and of using single or double column were studied in relation to the efficiency of ozone usage and the ratio of pollutant depletion. The ozone dosage required to treat both wastewaters with pollutant depletion of >90% was in the 5.5-8.5 mg/L range with ozone efficiencies greater than 80% depending on the type of wastewater and the operating conditions. This represented 100-200 mol of ozone transferred per mole of pollutant removed. Direct and indirect environmental impacts of ozonation were assessed according to Life Cycle Assessment, a technique that helped identify the most effective treatments in terms of potential toxicity reduction, as well as of toxicity reduction per unit mass of greenhouse-gas emissions, which were used as an indicator of environmental efficiency. A trade-off between environmental effectiveness (toxicity reduction) and greenhouse-gas emissions was observed since maximizing toxicity removal led to higher greenhouse-gas emissions, due to the latter's relatively high ozone requirements. Also, there is an environmental trade-off between effectiveness and efficiency. Our results indicate that an efficient use of ozone was not compatible with a full pollutant removal.

    During recent years, there has been growing interest in use of topical vehicle systems to assist in drug permeation through the skin. Drugs of interest are usually those that are problematic when given orally, such as piroxicam, a highly effective anti-inflammatory, anti-pyretic, and analgesic, but with the adverse effect of causing gastrointestinal ulcers. The present study investigated the in vitro and in vivo pharmacodynamic activity of a newly synthesized palm oil esters (POEs)-based nanocream containing piroxicam for topical delivery. A ratio of 25:37:38 of POEs: external phase: surfactants (Tween 80:Span 20, in a ratio 80:20), respectively was selected as the basic composition for the production of a nanocream with ideal properties. Various nanocreams were prepared using phosphate-buffered saline as the external phase at three different pH values. The abilities of these formulae to deliver piroxicam were assessed in vitro using a Franz diffusion cell fitted with a cellulose acetate membrane and full thickness rat skin. These formulae were also evaluated in vivo by comparing their anti-inflammatory and analgesic activities with those of the currently marketed gel. After eight hours, nearly 100% of drug was transferred through the artificial membrane from the prepared formula F3 (phosphate-buffered saline at pH 7.4 as the external phase) and the marketed gel. The steady-state flux through rat skin of all formulae tested was higher than that of the marketed gel. Pharmacodynamically, nanocream formula F3 exhibited the highest anti- inflammatory and analgesic effects as compared with the other formulae. The nanocream containing the newly synthesized POEs was successful for trans-dermal delivery of piroxicam.

    Piroxicam is a potent, nonsteroidal, anti-inflammatory agent (NSAID) which also exhibits antipyretic activity. The antiviral effect of piroxicam against herpes simplex virus type 1 (HSV-1) was examined in vitro on RC-37 monkey kidney cells using a plaque reduction assay. Piroxicam was dissolved in ethanol or dimethylsulfoxide (DMSO) and the 50% inhibitory concentration (IC50) was determined at 4 μg/ml and 75 μg/ml, respectively. The IC50 for the standard antiherpetic drug acyclovir was determined at 1.6 μM. At non-cytotoxic concentrations of these piroxicam solutions, plaque formation was significantly reduced by 62.4% for ethanolic piroxicam and 72.8% for piroxicam in DMSO. The mode of antiviral action of these drugs was assessed by time-on-addition assays. No antiviral effect was observed when cells were incubated with piroxicam prior to infection with HSV-1 or when HSV-1 infected cells were treated with dissolved piroxicam. Herpesvirus infection was, however, significantly inhibited when HSV-1 was incubated with piroxicam prior to the infection of cells. These results indicate that piroxicam affected the virus before adsorption, but not after penetration into the host cell, suggesting that piroxicam exerts a direct antiviral effect on HSV-1. Free herpesvirus was sensitive to piroxicam in a concentration-dependent manner and the inhibition of HSV-1 appears to occur before entering the cell but not after penetration of the virus into the cell. Considering the lipophilic nature of piroxicam, which enables it to penetrate the skin, it might be suitable for topical treatment of herpetic infections.

    Antibiotics are an important category of drugs in which indiscriminate use can affect the susceptibility patterns among infectious organisms, resulting in antibiotic resistance. Data on antibiotic usage and susceptibility patterns were collected from public and private health centres in Vijayawada, Andhra Pradesh, India, through the use of questionnaires. The data collected were then coded, tabulated, computed and evaluated using statistical analysis. The consumption profile of the different categories of drugs used in public and private hospitals was as follows: nutrition and metabolism products 19.0%; gastrointestinal disorder-related drugs 18.5%; antibiotics 16.8%; anti-pyretics and anti-analgesics 20.6%. These drugs were found to be in high demand. Among the antibiotics, aminoglycosides (amikacin), quinolones (ofloxacin, ciprofloxacin), tetracyclines (doxycycline), penicillin (ampicillin) and sulphonamides (co-trimoxazole) were the most commonly prescribed drugs for antibiotic therapy. 46% of the culture laboratory reports were positive with the following organism profile: Escherichia coli (36%), Klebsiella pneumoniae (16%), Staphylococcus aureus (29%), Enterococcus faecalis (9%) and Pseudomonas aeruginosa (10%). In terms of the sensitivity profile of antibacterials, amikacin (66.9%) was the only antibiotic showing sensitivity patterns, while the majority of antibiotics, such as cotrimoxazole, nalidixic acid, amoxicillin, gentamycin and norfloxacin, had acquired a resistance rate of 55.1%-80.6%. The results of this study suggest that indiscriminate prescription and consumption of new broad-spectrum antibiotics against sensitive organisms results in the development of antimicrobial resistance. Therefore, there is an urgent need to curb the excessive use of antibiotics in local hospitals in order to control the trend of increasing antimicrobial resistance to antibiotics.

    Full Text Available Dexibuprofen–antioxidant conjugates were synthesized with the aim to reduce its gastrointestinal effects. The esters analogs of dexibuprofen 5a–c were obtained by reacting its –COOH group with chloroacetyl derivatives 3a–c. The in vitro hydrolysis data confirmed that synthesized prodrugs 5a–c were stable in stomach while undergo significant hydrolysis in 80% human plasma and thus release free dexibuprofen. The minimum reversion was observed at pH 1.2 suggesting that prodrugs are less irritating to stomach than dexibuprofen. The anti-inflammatory activity of 5c (p < 0.001 is more significant than the parent dexibuprofen. The prodrug 5c produced maximum inhibition (42.06% of paw-edema against egg-albumin induced inflammation in mice. Anti-pyretic effects in mice indicated that prodrugs 5a and 5b showed significant inhibition of pyrexia (p < 0.001. The analgesic activity of 5a is more pronounced compared to other synthesized prodrugs. The mean percent inhibition indicated that the prodrug 5a was more active in decreasing the number of writhes induced by acetic acid than standard dexibuprofen. The ulcerogenic activity results assured that synthesized prodrugs produce less gastrointestinal adverse effects than dexibuprofen. The ex vivo antiplatelet aggregation activity results also confirmed that synthesized prodrugs are less irritant to gastrointestinal mucosa than the parent dexibuprofen. Molecular docking analysis showed that the prodrugs 5a–c interacts with the residues present in active binding sites of target protein. The stability of drug–target complexes is verified by molecular dynamic simulation study. It exhibited that synthesized prodrugs formed stable complexes with the COX-2 protein thus support our wet lab results. It is therefore concluded that the synthesized prodrugs have promising pharmacological activities with reduced gastrointestinal adverse effects than the parent drug.

    Full Text Available Abstract Background Influenza illness in children causes significant clinical and economic burden. Although some European countries have adopted influenza immunisation policies for healthy children, the debate about paediatric influenza vaccination in most countries of the European Union is ongoing. Our aim was to summarise influenza burden (in terms of health outcomes and economic burden in children in Western Europe via a systematic literature review. Methods We conducted a systematic literature search of PubMed, EMBASE, and the Cochrane Library (1970-April 2011 and extracted data on influenza burden in children (defined as aged ≤ 18 years from 50 publications (13 reporting laboratory-confirmed influenza; 37 reporting influenza-like illness. Results Children with laboratory-confirmed influenza experienced hospitalisations (0.3%-20%, medical visits (1.7-2.8 visits per case, antibiotic prescriptions (7%-55%, and antipyretic or other medications for symptomatic relief (76%-99%; young children and those with severe illness had the highest rates of health care use. Influenza in children also led to absenteeism from day care, school, or work for the children, their siblings, and their parents. Average (mean or median length of absence from school or day care associated with confirmed influenza ranged from 2.8 to 12.0 days for the children, from 1.3 to 6.0 days for their siblings, and from 1.3 to 6.3 days for their parents. Influenza negatively affected health-related quality of life in children with asthma, including symptoms and activities; this negative effect was smaller in vaccinated children than in non-vaccinated children. Conclusions Influenza burden in children is substantial and has a significant direct impact on the ill children and an indirect impact on their siblings and parents. The identified evidence regarding the burden of influenza may help inform both influenza antiviral use in children and paediatric immunisation policies in

    Full Text Available Piroxicam is one of the important therapeutic nonsteroidal anti-inflammatory class of drugs used mainly to suppress pain and inflammation in arthritis and other musculoskeletal disorders. Besides being anti-inflammatory, these drugs are analgesic and antipyretic often used for the relief of nonspecific fever condition. Recently, piroxicam has also gained attention as an effective therapy for tumors, colorectal, and invasive bladder cancers. The objective of the current study is to evaluate the protective effects of the alcoholic leaf extract of Hibiscus rosa-sinensis (AEH, Malvaceae, against piroxicam-induced toxicity in mice. Sixty adult Swiss albino mice ( Mus musculus were divided into four groups ( n = 10, which included a control group, a group treated orally with AEH (30 mg kg –1 b.w. for 15 days, a group treated orally with piroxicam (6.6 mg kg –1 b.w. for 15 days, and another group treated orally with piroxicam and AEH for 15 days. The results indicated that treatment with piroxicam alone resulted in a significant increase in the activities of serum marker enzymes, namely, aspartate transaminase, alanine transaminase, and alkaline phosphatase with profound hepatic lipid peroxidation as evidenced by a marked increment in the level of thoibarbituric acid reactive substances along with a distinct diminution in reduced glutathoine content and various antioxidant enzymes such as superoxide dismutase, catalase, and glutathione peroxidase in the liver. However, treatment with AEH during piroxicam treatment retrieved or partially antagonized the effects induced by piroxicam toward the normal values of controls. Histopathological observations also corroborate with the above findings. It can be concluded that AEH exhibited a protective action against piroxicam toxicity and effective in combating oxidative stress-induced hepatic damage.

    Full Text Available Background: Majority of Indian population is dependent on general practitioners (GPs for medical services at primary care level in India. They are most preferred and considered to be first contact person for medical services at primary care level. But advances in medical science has put more emphasis on specialist culture and average Bachelor of Medicine and Bachelor of Surgery (MBBS graduates who are working as general physician are gradually feeling themselves less competent because they are less exposed to latest advances in treatment of diseases. Amidst such scenario, Christian Medical College (CMC has come up with an idea: "The refer less and resolve more initiative". It has started a decentralized 2-year family medicine distance diploma course (Postgraduate Diploma in Family Medicine (PGDFM now accredited by Dr. MGR Medical University, Chennai, Tamil Nadu, that trains the GPs to become family medicine specialist. Materials and Methods: As component of PGDFM course, this study was conducted to provide better understanding of prevalent ailments and common treatment provided by the GPs in the community at present giving key insight of current practice in rural area by a registered family medicine practitioner. Results: As part of study, among 500 patients evaluated, three most common diagnosis were upper respiratory infections (URIs; 18%, acute gastroenteritis including water-borne diseases (15.8%, and anemia (10.4%. Treatment given to these patients comprised of mostly of antipyretic, analgesic, and antimicrobial agents. Most common drug prescribed was paracetamol for fever. Other common drugs prescribed were amoxicillin/clavulanic acid, chloroquine, artemisin derivative, doxycycline, co-trimoxazole, miltefosine, cephalexin, ceftriaxone sodium, cefixime, oral rehydration salts, ranitidine, omeprazole, pantoprazole, metronidazole, albendazole, ondansetron, diclofenac sodium, piroxicam, ibuprofen, diphenhydramine, codeine-sulfate, amlodipine

    Uncomplicated appendicitis may resolve spontaneously or require treatment with antibiotics or appendicectomy. The aim of this randomized trial was to compare the outcome of a non-antibiotic management strategy with that of antibiotic therapy in uncomplicated appendicitis. Patients presenting to a university teaching hospital with CT-verified uncomplicated simple appendicitis (appendiceal diameter no larger than 11 mm and without any signs of perforation) were randomized to management with a no-antibiotic regimen with supportive care (intravenous fluids, analgesia and antipyretics as necessary) or a 4-day course of antibiotics with supportive care. The primary endpoint was rate of total treatment failure, defined as initial treatment failure within 1 month and recurrence of appendicitis during the follow-up period. Some 245 patients were randomized within the trial, and followed up for a median of 19 months. The duration of hospital stay was shorter (mean 3·1 versus 3·7 days; P therapy without antibiotics. There was no difference in total treatment failure rate between the groups: 29 of 124 (23·4 per cent) in the no-antibiotic group and 25 of 121 (20·7 per cent) in the antibiotic group (P = 0·609). Eighteen patients (9 in each group) had initial treatment failure, 15 of whom underwent appendicectomy and three received additional antibiotics. Thirty-six patients (20 in the no-antibiotic group, 16 in the antibiotic group) experienced recurrence, of whom 30 underwent appendicectomy and six received further antibiotics. Treatment failure rates in patients presenting with CT-confirmed uncomplicated appendicitis appeared similar among those receiving supportive care with either a no-antibiotic regimen or a 4-day course of antibiotics.

    Dengue, a mosquito-borne viral disease, poses a significant global public health risk. In tropical countries such as India where periodic dengue outbreaks can be correlated to the high prevalence of the mosquito vector, circulation of all four dengue viruses (DENVs) and the high population density, a drug for dengue is being increasingly recognized as an unmet public health need. Using the knowledge of traditional Indian medicine, Ayurveda, we developed a systematic bioassay-guided screening approach to explore the indigenous herbal bio-resource to identify plants with pan-DENV inhibitory activity. Our results show that the alcoholic extract of Cissampelos pariera Linn (Cipa extract) was a potent inhibitor of all four DENVs in cell-based assays, assessed in terms of viral NS1 antigen secretion using ELISA, as well as viral replication, based on plaque assays. Virus yield reduction assays showed that Cipa extract could decrease viral titers by an order of magnitude. The extract conferred statistically significant protection against DENV infection using the AG129 mouse model. A preliminary evaluation of the clinical relevance of Cipa extract showed that it had no adverse effects on platelet counts and RBC viability. In addition to inherent antipyretic activity in Wistar rats, it possessed the ability to down-regulate the production of TNF-α, a cytokine implicated in severe dengue disease. Importantly, it showed no evidence of toxicity in Wistar rats, when administered at doses as high as 2g/Kg body weight for up to 1 week. Our findings above, taken in the context of the human safety of Cipa, based on its use in Indian traditional medicine, warrant further work to explore Cipa as a source for the development of an inexpensive herbal formulation for dengue therapy. This may be of practical relevance to a dengue-endemic resource-poor country such as India.

    Full Text Available Dengue virus (DENV and parvovirus B19 (B19V infections are acute exanthematic febrile illnesses that are not easily differentiated on clinical grounds and affect the paediatric population. Patients with these acute exanthematic diseases were studied. Fever was more frequent in DENV than in B19V-infected patients. Arthritis/arthralgias with DENV infection were shown to be significantly more frequent in adults than in children. The circulating levels of interleukin (IL-1 receptor antagonist (Ra, CXCL10/inducible protein-10 (IP-10, CCL4/macrophage inflammatory protein-1 beta and CCL2/monocyte chemotactic protein-1 (MCP-1 were determined by multiplex immunoassay in serum samples obtained from B19V (37 and DENV-infected (36 patients and from healthy individuals (7. Forward stepwise logistic regression analysis revealed that circulating CXCL10/IP-10 tends to be associated with DENV infection and that IL-1Ra was significantly associated with DENV infection. Similar analysis showed that circulating CCL2/MCP-1 tends to be associated with B19V infection. In dengue fever, increased circulating IL-1Ra may exert antipyretic actions in an effort to counteract the already increased concentrations of IL-1β, while CXCL10/IP-10 was confirmed as a strong pro-inflammatory marker. Recruitment of monocytes/macrophages and upregulation of the humoral immune response by CCL2/MCP-1 by B19V may be involved in the persistence of the infection. Children with B19V or DENV infections had levels of these cytokines similar to those of adult patients.

    Objectives: To evaluate the perceptions and extent of practicing self-medication among undergraduate pharmacy students. Methods: This cross-sectional, questionnaire-based study was conducted over a six month period (January to June 2016) among undergraduate pharmacy students in five reputable public universities of Bangladesh. It involved face-to-face interviews regarding self-medication of 250 respondents selected by simple random sampling. Results: Self-medication was reported by 88.0% of students. Antipyretics (58.40%) were mostly preferred for the treatment of fever and headaches. The major cause for self-medication was minor illness (59.60%, p = 0.73) while previous prescriptions were the main source of knowledge as well as the major factor (52.80%, p = 0.94) dominating the self-medication practice. The results also demonstrated 88.80% of students had previous knowledge on self-medication and 83.60% of students always checked the information on the label; mainly the expiry date before use (85.60%). A significant ( p self-medication to be a segment of self-care. Furthermore, students demonstrated differences in their response level towards the adverse effect of drugs, the health hazard by a higher dose of drug, a physician's help in case of side effects, taking medicine without proper knowledge, and stopping selling medicine without prescription. Conclusions: Self-medication was commonly used among pharmacy students primarily for minor illnesses using over-the-counter medications. Although it is an inevitable practice for them it should be considered an important public health problem as this practice may increase the misuse or irrational use of medicines.

    Full Text Available Bacopa monnieri (L. Wettst. (BM, a traditional Ayurvedic medicine, used for centuries as a memory enhancing, anti-inflammatory, antipyretic, sedative and antiepileptic agent. BM extract have been extensively investigated by several authors for their neuropharmacological effects. In nuclear medicine, red blood cells (RBC labeled with technetium-99m (99mTc have several clinical applications. However, data have demonstrated that synthetic or natural drugs could modify the labeling of RBC with 99mTc. As Bacopa monnieri is extensively used in medicine, we evaluated its influence on the labeling of RBC and plasma proteins using technetium-99m (99mTc. This labeling procedure depends on a reducing agent and usually stannous chloride is used. Blood was incubated with BM extracts. Stannous chloride solution and 99mTc were added. Blood was centrifuged and plasma (P and blood cells (BC were isolated. Samples of P or BC were also precipitated, centrifuged and insoluble fraction (IF and soluble fraction (SF were separated. The percentage of radioactivity (%ATI in BC, IF-BC and IF-P were calculated. The %ATI significantly decreased on BC from 95.53±0.45 to 35.41±0.44, on IF-P from 80.20±1.16 to 7.40±0.69 and on IF-BC from 73.31±1.76 to 21.26±1.40. The morphology study of RBC revealed important morphological alterations due to treatment with BM extracts. We suggest that the BM extract effect could be explained by an inhibition of the stannous and pertechnetate ions or oxidation of the stannous ion or by damages induced in the plasma membrane.

If the growth promotion relates with positive microorganisms and growth elimination is connected with pathogens the results is nutrients utilization improvement, stimulation of immunologic system or positive influence of intermedial metabolism. Anethole is one of these important plant metabolites. There are described following positive effects of anethole in human medicine: vasorelaxant, antithrombotic, releasing of heart function, fytoestrogenic (it mean improving of milk secretion, menstruation, promotion of menses, birth improvement, men’s hormonal changes improving, sexual libido improving, antioxidative, antifungal, improvement of derma permeability, antihelmintic, insecticidal, yeast elimination, antibacterial, antipyretic.In our work the effect of anise and fennel essential oils on nutrients utilization in pig experiment was evaluated. The trial was organized in accredited experimental stable Žabčice of Mendel University of Agriculture and Forestry Brno. The high level efficiency of experimental animals is mentioned through general parameters (average daily gain, feed intake and feed conversion. The results of nutrients utilization rate show slightly higher digestibility of nutrients in treatment with anise oil, this improvement is not higher then 1.0 %. We can see also improvement of nitrogen retention in body mass on level of 5.6 % (anise treatment compared with control group. There is low variability between experimental animals (except nitrogen retention coefficient but we can not see any statistical significance. On base of these results we can say the used phytogenic additives do not affect negatively the nutrient utilization in used concentration (0.1 % of essential oil in feed mixture and are fully eligible for animal nutrition. These results are also supported by few

    To describe the prevalence of prescribed and self-medicated use of medication in the Spanish Roma population, and identify the associated factors. Descriptive cross-sectional study. Data from the first National Health Survey conducted on the Roma population in Spain were used. The sample comprised 1000 Spanish Roma adults of both sexes aged ≥16 years. Answers (yes/no) to the question, 'In the last two weeks have you taken the following medicines [in reference to a list of medicines that might be used by the population] and were they prescribed for you by a doctor?' were used to ascertain 'medication use'. 'Self-medication' referred to use of these medicines without medical prescription. Using multivariate logistic regression models, odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to identify associated factors. The overall prevalence of medication use in the Roma population for both sexes was 69.1%, and 38.7% was self-medicated. Females reported higher use of medication than males (75.1% vs 62.3%); however, self-medication was higher among males. Analgesics and antipyretics were used most often (35.8%). Among males, the variables that were independently and significantly associated with a higher probability of medication use were: age; negative perception of health; presence of chronic disease (OR 2.81; 95% CI 1.67-4.73); and medical visits (OR 4.51; 95% CI 2.54-8.01). The variables were the same among females, except for age. A high percentage of the Spanish Roma population use medication, and a significant proportion of them self-medicate. The presence of chronic diseases, a negative perception of health and medical consultations were associated with increased use of medication in the study population.

    Full Text Available Farm animals are reared for production to meet up the demand for animal protein in human. Various modern medicines are extensively used for production as well as treatment and prevention of diseases of animals, which can ultimately reach us through food chain. Herbs are now considered as an important source of alternative medicines. The Ayurvedic medicines prepared by manufacturers contain processed plant parts and added with preservative and other chemicals in many cases. The present way of research on herbal medicine follows the path of identification of active principles from the extracts of preserved parts of medicinal plants after testing of their efficacy in laboratory. This concept of research have the limitation of loss of many aromatic and other phytochemicals present in the living plant, which may have very important role when used together. Animals maintained in modern farm may be given relief from modern medicines in minor and moderate ailments, cure of problems related with their production with the validated fresh plant medicine available from the plants cultivated adjacent to the farm area. Consulting the reports of ethno-botanical study, a preliminary list of medicinal plant is prepared which are having antipyretic, analgesic, wound healing, immunostimulant, hepato-protective, fertility enhancing, pregnancy assisting, lactation assisting, anthelmintic, astringent, expectorant, purgative and anti-flatulent, nutriceutical, antiseptic, anti-dermatitis, anti-dysenteric and anti-enteric, hematenic, stomachic, diuretic and kidney stone removing effects and insecticidal or insect repelling effects. This list may be enriched further and plants may be selected for a farm from these groups according to the agro-climatic condition of the area, disease prevalence, problems encountered during farming practice and other requirements of the farm. Validation of reported effects of the plants is to be performed in fresh condition, so that parts

    Full Text Available American wormseed oil, also known as Chenopodium ambrosioides oil, is obtained from the herbs of the genus Chenopodium which comprises more than 200 species and belongs to the geographical region of Asia, Europe, China, India, America and other countries. Chenopodium has been traditionally used for digestive, respiratory, diabetes, uro-genital, nervous and vascular disorders and has antihelminthic, vermifuge, emmenagogue sedative, antipyretic, antirheumatic and abortifacient activities. Ascaridole is a bicyclic monoterpene commonly known as ascarisin or 1,4-epidioxy-p-menth-2-ene which have sedative, antifungal and painrelieving properties. It is a potent inhibitor of Trypanosoma cruzi, Plasmodium falciparum, and Leishmania amazonensis and is well known for its worm-expelling potential. Ascaridole was firstly isolated by a German pharmacist in the 1900’s and at that time it was one of the best antihelmintics for the treatment of ascarids and hookworms in humans and other species like cats, dogs, horses and pigs. Ascaridole could be extracted by using a non-polar solvent hexane due to its very poor solubility in water. From the literature support, it has been proved that ascaridole have very high potential in the modern and other system of medicine for the treatment of various disorders. So on the basic of its uses, here we have collected and compiled all the data regarding its medicinal uses, pharmacological activities and analytical techniques of the ascaridole in the present review and expected that this review will be beneficial for the researcher in the field of medicine and other allied science.

    Tuberous roots of Chlorophytum borivilianum Sant. et Fernand. which are a source of steroidal saponins, possess immunomodulatory, adaptogenic, aphrodisiac, antipyretic, diuretic, hemostatic and anti-tumour properties. Poor seed setting and germination and slow growth in conventional vegetative propagation are major constraints in the large-scale cultivation of this commercially important medicinal plant. In the present study, a procedure for in vitro propagation of this endangered herb through somatic embryogenesis has been established. Seeds of Chlorophytum borivilianum were germinated on MS medium supplemented with 57.74 μM gibberellic acid and hypocotyl portion from germinated seedling was used as explant for callus induction. Moderate to good callus induction was observed on MS medium containing 1.16 μM kinetin and 1.13-2.26 μM 2,4-dichlorophenoxyacetic acid. Regular subculturing of callus on kinetin (1.16 μM) and 2,4-dichlorophenoxyacetic acid (1.13 μM) supplemented medium induced somatic embryogenesis. In modified MS medium, 1.79 mM NH4NO3 and 10.72 mM KNO3 was optimal for somatic embryogenesis. 7.38 μM 2-isopentenyladenine supplemented to modified MS medium, showed best response for somatic embryogenesis while proline (0.76 mM) as an amino acid supplement gave better response than glutamine. 30% germination of mature somatic embryos was achieved on MS medium supplemented with 15.54 μM 6-benzylaminopurine. Multiplication of C. borivilianum through somatic embryogenesis may offer a better approach compared to organogenesis for developing scale-up technology employing bioreactors for its mass propagation.

    Tenoxicam is a non-steroidal antiinflammatory drug, which has antipyretic and antiinflammatory effects. Though it is known that the major side effect of non-steroidal antiinflammatory drugs is on the gastrointestinal tract and liver, there have been few studies regarding the effects of tenoxicam. In this study, we aimed to investigate whether tenoxicam has a deleterious effect on liver tissue using immunohistochemical staining and biochemical analysis. A total of 30 male Wistar albino rats were included in this study. Animals were equally and randomly divided into three groups as follows: Group I (Controls), Group II (Injection with 10 mg/kg/day of tenoxicam) and Group III (Injection with 20 mg/kg/day of tenoxicam). At the end of the study, some liver tissue samples were taken and kept in neutral formalin for histological and immunohistochemical evaluation. Liver tissue samples were embedded in paraffin blocks after routine tissue preparation procedures, and were stained with hematoxylin-eosin and immunohistochemical stain. Liver samples taken for biochemical analysis were washed with physiological saline. Thiobarbituric acid reactive substances and superoxide dismutase activity were measured in the obtained supernatants. There were significant structural changes in liver tissues of the tenoxicam-administered groups when compared with the controls. We observed that hepatic (inducible nitric oxide synthase) receptors were increased in the study groups. Furthermore, hepatic superoxide dismutase and malondialdehyde levels were prominently higher in the tenoxicam-administered groups when compared to levels of the control group. Nitric oxide may exert an antioxidative effect against lipid peroxidation to one point at low levels; however, it may also have the opposite effect at higher levels in tenoxicam induced liver injury.

    Andrographolide sodium bisulfite (ASB), a water-soluble sulfonate of andrographolide has been shown to possess anti-inflammatory, antipyretic and analgesic activities. However, there is no report on the gastroprotective effect of ASB against indomethacin-induced gastric ulcer. Here we investigated the possible anti-ulcerogenic potential of ASB and the underlying mechanism against indomethacin-induced gastric ulcer in rats. The ulcer area, histopathological assessment, contents of gastric mucosal glutathione (GSH), catalase (CAT), superoxide dismutase (SOD), malonaldehyde (MDA) and prostaglandin E2 (PGE2) were examined. In addition, cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2) mRNA expression and immunohistochemical evaluation of HSP70, Bcl-2 and Bax proteins were also investigated. Results indicated that ASB pre-treatment significantly reduced the ulcer areas induced by indomethacin compared with the vehicle group. The gastric levels of GSH, CAT and SOD were markedly increased by ASB while the level of MDA was decreased. In addition, ASB pretreatment significantly promoted the gastric PGE2 levels and up-regulated the COX-1 and COX-2 mRNA expression in comparison with the vehicle group. Immunohistochemistry analysis showed obvious up-regulation of HSP70 and Bcl-2 protein expression while suppression of Bax protein in the gastric tissue of ASB-pretreated group. Taken together, these findings indicated that the gastroprotective effect of ASB might be associated with the improvement of antioxidative status, activation of COX-mediated PGE2 synthesis, down-regulation of Bax proteins and up-regulation of Bcl-2 and HSP70 proteins. ASB might have the potential for further development as a promising alternative for antiulcer treatment. Copyright © 2015 Elsevier B.V. All rights reserved.

The prevalence of self-medication was 80.9% (n=389. The most common reasons for self-medication were related to their knowledge of their ailment and its treatment (58.0%, 14.4% thought it saved time and 8.5% mentioned that medication given by provider was not effective. The most common symptoms were otorhinolaryngology problems (22.5%, followed by respiratory disease (19.6%, Gastro Intestinal Tract (GIT disease (18.1% and headache/fever (16.8%. Commonly used medicines were analgesics & antipyretics (30.2%, ear, nose & throat drugs (10.8%, vitamins & minerals (10.8%, GIT drugs (8.5%, anti-infections (7.3% and herbal medicines (3.5%. Prevalence of medicine storage and self-medication practice is high among educated female students in USM.Conclusions: There is a need to educate the students to ensure safe practice by increasing their awareness. Strict policies need to be implemented on the unrestricted availability of medicines so as to prevent the wastage of medicines.

  7. The effect of radiation on some salicylates. 1. Steady state studies

    This work was undertaken to obtain more quantitative information on the extent and nature of the degradation of some salicylates by ionizing radiation, especially gamma rays, and to gather data that could assist in the evaluation of the use of radiation for sterilization of this group of compounds which are extensively used as antipyretics, analgesics and anti-rheumatics. Salicylamide is not only a common medicinal, but also a model for the study of the effect of radiation on biological systems. A 3200 Ci Co-60 facility was used. Three salicylates were subjected to solid phase irradiation, namely: salicylamide, phenylsalicylate, and acetyl salicylic acid (aspirin). These compounds were purified by repeated recrystallization from water, methanol and benzene, respectively, until a constant melting point was obtained. Irradiation in the solid phase was made in doses from 2.5 to 240 Krad. Irradiation in the liquid phase (solution) was carried out in doses, ranging from 2000 to as high as 270,000 rad depending on the reactivity of the solution. The degradation products were separated by thin layer chromatography using Kieselgel F254 and SIF with fluorescence scintillator (Riedel-de Haen). The products were visualized with a Camag UV Universal lamp. Irradiation of the three salicylates showed very little decomposition even at doses very much higher than those required for radiation sterilization. Salicylamide appears to be the most stable giving an initial G(-salicylamide)-0.50. For both phenylsalicylate and acetylsalicylic acid only the G values at 150 Mrad were obtained as the amounts degraded at lower doses were too low for the sensitivity of the diffused reflectance method used. A G(-phenylsalicylate)-2 and G(-acetylsalicylate)-1.2 were obtained by this method. Salicylic acid is formed when aspirin is irradiated. It is concluded that this acid is one of the degradation products. Barring any toxic property of the minute substances formed, solid phase sterilization is

    The purpose of the present study was to better understand the events involved in the febrile response induced by cecal ligation and puncture (CLP), a complex infectious process. To this end, we conducted in vivo experiments in rats examining (1) fever development, (2) bacterial number in the infection focus and in blood, (3) peripheral and hypothalamic synthesis of cytokines, (4) hypothalamic and cerebrospinal fluid (CSF) synthesis of prostaglandin E(2) (PGE(2)), (5) the effect of anti-IL-6 antibody on fever, and (6) the effect of celecoxib on fever and hypothalamic synthesis of PGE(2) after CLP induction. We found that CLP promotes fever and animal death depending on the number of punctures. The peak of CLP-induced fever overlapped with the maximal increase in the number of bacteria in the infectious focus and blood, which occurred at 6 and 12 h. The peak of the febrile response also coincided with increased amounts of interleukin (IL)-1β, IL-6 and IL-10 in the peritoneal exudate and serum; IL-6 in the hypothalamus and PGE(2) in the CSF and predominantly in the hypothalamus. Moreover, intracerebroventricularly injected anti-IL-6 antibody reduced the febrile response while celecoxib reduced the fever and PGE(2) amount in the hypothalamus induced by CLP. Tumor necrosis factor (TNF)-α peaked at 3 h at all sites studied. Conversely, IL-10 concentration decreased in the hypothalamus. These findings show that the peak of CLP-induced fever is accompanied by an increase of bacteria in peritoneal fluid (local infection) and blood; local synthesis of pyrogenic (IL-1β, IL-6) and antipyretic (IL-10) cytokines and central production of IL-6 and PGE(2), suggesting that these last are the central mediators of this response.

    The Condalia buxifolia root bark infusion is used in traditional medicine in Brazil as antipyretic, anti-inflammatory and anti-dysentery. Previous data from our group showed that methanolic extract of Condalia buxifolia (MECb) produced a marked antinociceptive effect in animal models of acute pain. The purpose of this study was to investigate the mechanisms of MECb-induced antinociception as measured by nocifensive behavior in pain induced by endogenous (prostaglandin E2) or exogenous (TRPs and ASIC agonist, and protein kinase A and C activators) chemical stimuli, and the potential role of PKA signaling and capsaicin-sensitive central C-fiber afferents. The effect of MECb administered orally (0.1-300mg/kg, i.g.) to mice on nociception induced by capsaicin (TRPV1 agonist), cinnamaldehyde (TRPA1 agonist), menthol (TRPM8 agonist), acidified saline (ASIC agonist), PMA (protein kinase C activator), PGE2 and forskolin (protein kinase A activator) was assessed. Moreover, this study also investigated the role of C-fibers desensitizing mice with a high dose of intrathecal capsaicin. Furthermore, this study performed the western blot to PKA phosphorylated on nocifensive behavior induced by forskolin. MECb was able to reduce the nociception and paw edema induced by capsaicin, acidified saline, PMA, PGE2 and forskolin, but not by cinnamaldehyde or menthol. Western blot analyses showed that MECb reduced the levels of PKA phosphorylation induced by forskolin in hind paws. Finally, ablating central afferent C-fibers abolished MECb antinociception. In accordance with its use in traditional medicine, these findings provide new evidence indicating that Condalia buxifolia reduces the acute painful behavior of animals caused by chemical stimuli. The precise mechanism of MECb antinociceptive activity is not completely understood but the results suggest involvement of PGE2, TRPV1/ASIC and PKA signaling pathways, and require integrity of the capsaicin-sensitive central C-fiber afferents

    Full Text Available Self-medication habit of antibiotics contributes to the bacterial resistance mechanism, which is a global public health problem that must be prevented. The university student, as a future health professional, is summoned to guide a conduct and report on the use of antimicrobials regarding the casual agent, the site of infection and the severity of the disease. In this study, it has been verified, through a questionnaire, the profile of freshmen and academic students who are majoring in Biomedical Science in an institution of higher education, comparing the results obtained. It is a descriptive study with quantitative data approach (relative frequency – % through a self-administered questionnaire, and containing 13 multiple choice questions stored in the database in Excel. The sample consisted of 132 undergraduate students from the Biomedical Science course from this University Center. Among the freshmen, the purchase of antibiotic is mainly influenced by previous experiences with the drug, what is not repeated by the students that are graduating and prefer to seek and follow medical advice. Thus, 91.8% of trainees believe that self-medication may be harmful to health. Regarding the use of anti-inflammatory, analgesic and antipyretic before the use of antibiotics, 67% of the entering students said that they take these medications, against 70% of the senior students that also do it. Therefore, we may conclude that information on the danger of self-medication is provided in the disciplines of microbiology and pharmacology, which have not been studied by the freshmen and is unknown by the general population, that appeals to self-medication due to the lack of knowledge. To reverse this situation, it is necessary a greater media exposure on educational practices regarding the risks, the benefits, and elucidation about multi-resistant bacteria.

    Betulinic acid (pentacyclic triterpenoid) is an important marker component present in Nelumbo nucifera Gaertn. rhizome. N. nucifera rhizome has several medicinal uses including hypoglycaemic, antidiarrhoeal, antimicrobial, diuretic, antipyretic, psychopharmacological activities. To establish a simple, sensitive, reliable, rapid and validated high-performance thin-layer chromatography method for estimation of betulinic acid in hydro-alcoholic extract of N. nucifera Gaertn. rhizome. The separation was carried out on a thin-layer chromatography aluminium plate pre-coated with silica gel 60F(254) , eluted with chloroform, methanol and formic acid (49 : 1 : 1 v/v). Post chromatographic derivatisation was done with anisaldehyde-sulphuric acid reagent and densitometric scanning was performed using a Camag TLC scanner III, at 420 nm. The system was found to produce a compact spot for betulinic acid (R(f) = 0.30). A good linear precision relationship between the concentrations (2-10 µg) and peak areas were obtained with the correlation coefficient (r) of 0.99698. The limit of detection and limit of quantification of betulinic acid were detected to be 0.4 and 2.30 µg per spot. The percentage of recovery was found to be 98.36%. The percentage relative standard deviations of intra-day and inter-day precisions were 0.82-0.394 and 0.85-0.341, respectively. This validated HPTLC method provides a new and powerful approach to estimate betulinic acid as phytomarker in the extract. Copyright © 2010 John Wiley & Sons, Ltd.

    The aim of this study was to investigate the protective effects of phospholipase A2 (PLA2) from bee venom against acetaminophen-induced hepatotoxicity through CD4+CD25+Foxp3+ T cells (Treg) in mice. Acetaminophen (APAP) is a widely used antipyretic and analgesic, but an acute or cumulative overdose of acetaminophen can cause severe hepatic failure. Tregs have been reported to possess protective effects in various liver diseases and kidney toxicity. We previously found that bee venom strongly increased the Treg population in splenocytes and subsequently suppressed immune disorders. More recently, we found that the effective component of bee venom is PLA2. Thus, we hypothesized that PLA2 could protect against liver injury induced by acetaminophen. To evaluate the hepatoprotective effects of PLA2, C57BL/6 mice or interleukin-10-deficient (IL-10-/-) mice were injected with PLA2 once a day for five days and sacrificed 24 h (h) after acetaminophen injection. The blood sera were collected 0, 6, and 24 h after acetaminophen injection for the analysis of aspartate aminotransferase (AST) and alanine aminotransferase (ALT). PLA2-injected mice showed reduced levels of serum AST, ALT, proinflammatory cytokines, and nitric oxide (NO) compared with the PBS-injected control mice. However, IL-10 was significantly increased in the PLA2-injected mice. These hepatic protective effects were abolished in Treg-depleted mice by antibody treatment and in IL-10-/- mice. Based on these findings, it can be concluded that the protective effects of PLA2 against acetaminophen-induced hepatotoxicity can be mediated by modulating the Treg and IL-10 production.

    Here we aimed to investigate the in vitro effects of three analgesic-antipyretic drugs frequently used in clinical practice in Mexico - acetaminophen (AAP), aspirin (ASA) and metamizole (MMZ) - on serum measurements of glucose, urea, and creatinine. Each analyte was measured in a base-serum pool spiked with the drugs at subtherapeutic, therapeutic, and toxic doses. Serum glucose and urea were measured using the hexokinase/G-6PDH and urease/GLDH kinetic assays, respectively. Serum creatinine (SCr) was measured with a Jaffe procedure based on the alkaline-picrate reaction and with an enzymatic dry-chemistry system. Measurements were carried out in IL-Monarch and Vitros DT60-II analyzers, respectively. Data were analyzed by the difference-paired interference test and by ANOVA. By the kinetic Jaffe/Monarch procedure, we found positive interference by the drugs on the SCr measurements and by only ASA for urea measurement. For creatinine measurements, the total errors (TEs) were 22-51%, 18-105%, and 15-26% for AAP, ASA, and MMZ respectively, while for urea measurement the TE was 16-21% for ASA. A negative interference by MMZ on SCr (TE=-47%), but no-interference for AAP or ASA, were found via the enzymatic/DT60-II system. In vitro positive interference induced by AAP, ASA, and MMZ (via the alkaline-picrate reaction), or negative interference by MMZ (via a dry-chemistry system), on the SCr measurements highlights the importance of investigating all possible sources of variation that may alter the accuracy of the laboratory tests, in order to provide useful results for making medical decisions for optimal patient care.

    A Salmonella enterica epidemic occurred in children of the area of L'Aquila (Central Italy, Abruzzo region) between June 2013 and October 2014, four years after the catastrophic earthquake of 6 April 2009. Clinical and laboratory data were collected from hospitalized and ambulatory children. Routine investigations for Salmonella infection were carried out on numerous alimentary matrices of animal origin and sampling sources for drinking water of the L'Aquila district, including pickup points of the two main aqueducts. Salmonella infection occurred in 155 children (83 females: 53%), aged 1 to 15 years (mean 2.10). Of these, 44 children (28.4%) were hospitalized because of severe dehydration, electrolyte abnormalities, and fever resistant to oral antipyretic and antibiotic drugs. Three children (1.9%) were reinfected within four months after primary infection by the same Salmonella strain. Four children (2.6%), aged one to two years, were coinfected by rotavirus. A seven-year old child had a concomitant right hip joint arthritis. The isolated strains, as confirmed in about the half of cases or probable/possible in the remaining ones, were identified as S. enterica serovar Typhimurium [4,5:i:-], monophasic variant. Aterno river, bordering the L'Aquila district, was recognized as the main responsible source for the contamination of local crops and vegetables derived from polluted crops. The high rate of hospitalized children underlines the emergence of a highly pathogenic S. enterica strain probably subsequent to the contamination of the spring water sources after geological changes occurred during the catastrophic earthquake.

    Full Text Available Most patients with bacterial infections suffer from fever and various pains that require complex treatments with antibiotics, antipyretics, and analgaesics. The most common drugs used to relieve these symptoms are non-steroidal anti-inflammatory drugs (NSAIDs, which are not typically considered antibiotics. Here, we investigate the effects of NSAIDs on bacterial susceptibility to antibiotics and the modulation of bacterial efflux pumps.The activity of 12 NSAID active substances, paracetamol (acetaminophen, and eight relevant medicinal products was analyzed with or without pump inhibitors against 89 strains of Gram-negative rods by determining the MICs. Furthermore, the effects of NSAIDs on the susceptibility of clinical strains to antimicrobial agents with or without PAβN (Phe-Arg-β-naphtylamide were measured.The MICs of diclofenac, mefenamic acid, ibuprofen, and naproxen, in the presence of PAβN, were significantly (≥4-fold reduced, decreasing to 25-1600 mg/L, against the majority of the studied strains. In the case of acetylsalicylic acid only for 5 and 7 out of 12 strains of P. mirabilis and E. coli, respectively, a 4-fold increase in susceptibility in the presence of PAβN was observed. The presence of Aspirin resulted in a 4-fold increase in the MIC of ofloxacin against only two strains of E. coli among 48 tested clinical strains, which included species such as E. coli, K. pneumoniae, P. aeruginosa, and S. maltophilia. Besides, the medicinal products containing the following NSAIDs, diclofenac, mefenamic acid, ibuprofen, and naproxen, did not cause the decrease of clinical strains' susceptibility to antibiotics.The effects of PAβN on the susceptibility of bacteria to NSAIDs indicate that some NSAIDs are substrates for efflux pumps in Gram-negative rods. Morever, Aspirin probably induced efflux-mediated resistance to fluoroquinolones in a few E. coli strains.

    Recovery from cytomegalovirus meningoencephalitis with brain stem death in an immunocompetent patient is almost impossible. We present a remarkable recovery from a possible cytomegalovirus infection in an immunocompetent man who had severe neurological syndromes, suggesting brain stem death complicated by pneumonia and pleural effusion. A 19-year-old Asian man presented at our hospital's emergency department with reduced consciousness and seizures following high fever, headache, confusion, and vomitus within a week before arrival. He was intubated and sent to our intensive care unit. He had nuchal rigidity and tetraparesis with accentuated tendon reflexes. Electroencephalography findings suggested an acute structural lesion at his right temporal area or an epileptic state. A cerebral spinal fluid examination suggested viral infection. A computed tomography scan was normal at the early stage of disease. Immunoglobulin M, immunoglobulin G anti-herpes simplex virus, and immunoglobulin M anti-cytomegalovirus were negative. However, immunoglobulin G anti-cytomegalovirus was positive, which supported a diagnosis of cytomegalovirus meningoencephalitis. His clinical condition deteriorated, spontaneous respiration disappeared, cranial reflexes became negative, and brain stem death was suspected. Therapy included antivirals, corticosteroids, antibiotics, anticonvulsant, antipyretics, antifungal agents, and a vasopressor to maintain hemodynamic stability. After 1 month, he showed a vague response to painful stimuli at his supraorbital nerve and respiration started to appear the following week. After pneumonia and pleural effusion were resolved, he was weaned from the ventilator and moved from the intensive care unit on day 90. This case highlights several important issues that should be considered. First, the diagnosis of brain stem death must be confirmed with caution even if there are negative results of brain stem death test for a long period. Second, cytomegalovirus

    Full Text Available BackgroundSelf-medication results in wastage of resources, increases resistance of pathogens and generally causes serious health hazards such as adverse drug reactions, prolonged suffering and drug dependence. This study was undertaken to determine the reasons for self-medication and the pattern of self-medication among medical students.MethodThis cross-sectional descriptive study was conducted at the K.S. Hegde Medical Academy, Mangalore. The participants were medical students from first to final year. Medical students were selected through convenience sampling. The data was collected using a pre-tested semi-structured questionnaire. The data was analysed using SPSS version 16 and the results expressed as proportions.ResultsA total of 200 students, 121 (60.5% female and 79 (39.5% male, were included in the study. Of the medical students surveyed, self-medication was reported among 92%. The respondents who used self-medication found it to be time-saving in providing relief from minor ailments. The most common ailments for which self-medication were used were: the common cold (69%, fever (63% and headache (60%. The students consulted their textbooks (39% and seniors or classmates (38% for the medications. Antipyretics (71%, analgesics (65%, antihistamines (37% and antibiotics (34% were the most common self-medicated drugs. Of the respondents, 33% were unaware of the adverse effects of the medication and 5% had experienced adverse reactions. The majority (64% of students advised medications to others, more often to family and friends.ConclusionThe prevalence of self-medication among medical students is high, facilitated by the easy availability of drugs and information from textbooks or seniors. A significant number of students are unaware of the adverse effects of the medication that they themselves take and suggest to others. Therefore, potential problems of self-medication should be emphasised to the students.

    To compare the effectiveness of Homeopathy and Conventional therapy in Acute Otitis Media (AOM). A randomized placebo-controlled parallel group pilot study of homeopathic vs conventional treatment for AOM was conducted in Jaipur, India. Patients were randomized by a computer generated random number list to receive either individualized homeopathic medicines in fifty millesimal (LM) potencies, or conventional treatment including analgesics, antipyretics and anti-inflammatory drugs. Patients who did not improve were prescribed antibiotics at the 3rd day. Outcomes were assessed by the Acute Otitis Media-Severity of Symptoms (AOM-SOS) Scale and Tympanic Membrane Examination over 21 days. 81 patients were included, 80 completed follow-up: 41 for conventional and 40 for homeopathic treatment. In the Conventional group, all 40 (100%) patients were cured, in the Homeopathy group, 38 (95%) patients were cured while 02 (5%) patients were lost to the last two follow-up. By the 3rd day of treatment, 4 patients were cured in Homeopathy group but in Conventional group only one patient was cured. In the Conventional group antibiotics were prescribed in 39 (97.5%), no antibiotics were required in the Homeopathy group. 85% of patients were prescribed six homeopathic medicines. Individualized homeopathy is an effective conventional treatment in AOM, there were no significant differences between groups in the main outcome. Symptomatic improvement was quicker in the Homeopathy group, and there was a large difference in antibiotic requirements, favouring homeopathy. Further work on a larger scale should be conducted.

    Full Text Available Abstract Background During the first days after stroke, one to two fifths of the patients develop fever or subfebrile temperatures. Body temperature is a strong prognostic factor after stroke. Pharmacological reduction of temperature in patients with acute ischaemic stroke may improve their functional outcome. Previously, we studied the effect of high dose (6 g daily and low dose (3 g daily paracetamol (acetaminophen in a randomised placebo-controlled trial of 75 patients with acute ischemic stroke. In the high-dose paracetamol group, mean body temperature at 12 and 24 hours after start of treatment was 0.4°C lower than in the placebo group. The effect of ibuprofen, another potent antipyretic drug, on body-core temperature in normothermic patients has not been studied. Aim The aim of the present trial is to study the effects of high-dose paracetamol and ibuprofen on body temperature in patients with acute ischaemic stroke, and to study the safety of these treatments. Design Seventy-five (3 × 25 patients with acute ischaemic stroke confined to the anterior circulation will be randomised to treatment with either: 400 mg ibuprofen, 1000 mg acetaminophen, or with placebo 6 times daily during 5 days. Body-temperatures will be measured with a rectal electronic thermometer at the start of treatment and after 24 hours. An infrared tympanic thermometer will be used to monitor body temperature at 2-hour intervals during the first 24 hours and at 12-hour intervals thereafter. The primary outcome measure will be rectal temperature at 24 hours after the start of treatment. The study results will be analysed on an intent-to-treat basis, but an on-treatment analysis will also be performed. No formal interim analysis will be carried out.

    Full Text Available OBJECTIVE: Determine the prevalence of medication use in children and adolescents in 20 municipalities of Vale do Jequitinhonha, Minas Gerais-Brazil, showing the main groups and variables that may have influenced use. METHODS: Descriptive population-based survey sample of 555 interviews, selected by simple random cluster sampling of 137 census tracts. Inclusion criteria were age ≤ 14 years, mandatory interview with the legal guardians, and regardless of having received medications. Regarding the usage pattern, participants were divided into two groups: consumption and non-consumption of drugs. A descriptive analysis of the variables and tests of association were performed. RESULTS: The prevalence of drug consumption was 56.57%, and 42.43% showed no consumption. The use of medicinal plants was 72.9% for drug users and 74.3% for non-users. The health conditions for consumption were cough, common cold, flu, nasal congestion or bronchospasm (49.7%, fever (5.4%, headache (5.4%, diarrhea, indigestion, and abdominal colic (6.7%. In cases of self-medication, 30.57% of the drugs were given by the mother, and 69.42% were prescription drugs. Self-medication was prevalent using paracetamol (30.2%, dipyrone (20.8%, and cold medicine (18.8%. There was increased use of analgesics/antipyretics, followed by respiratory medications, systemic antibiotics, histamine H1 antagonists, and vitamins/antianemics. CONCLUSIONS: The prevalence of drugs use in children was high, indicating the need for formulating educational programs aiming at the awareness of caregivers regarding rational use.

The aim of the study was to examine the trends in opioid and nonopioid analgesic consumption in Croatia between 2007 and 2013. Methods: Data on opioid consumption were extracted from the database of the national authority. All opioid and nonopioid analgesics were included in the analysis. Data were presented as defined daily doses per 1,000 inhabitants per day. Adequacy of opioid consumption was calculated using adequacy of consumption measure. Results: During the examined 7-year period, the total consumption and total cost of all analgesics in Croatia showed continuous increase. In the M01A group (anti-inflammatory and antirheumatic products, nonsteroids, ibuprofen had an exponential increasing trend, and in 2011, it overtook diclofenac consumption. Ibuprofen and diclofenac had the highest consumption also in the M02A group of topical products for joint and muscular pain. Tramadol was by far the most consumed type of opioids (N02A group and paracetamol in the group of other analgesics and antipyretics (N02B. The adequacy of consumption measure value was 0.19, indicating that Croatia is a country with a low opioid consumption. Conclusion: Between 2007 and 2013, both consumption of analgesics and their cost in Croatia had an increasing trend. Comparisons with data from other countries, based on the published literature, indicate that analgesic consumption in Croatia is still relatively low. Calculation of the adequacy of opioid consumption indicated that Croatia is a country with low opioid consumption. Further studies are necessary for establishing whether current analgesic consumption in

    Self-medication is a widely prevalent practice in India. It assumes a special significance among medical students as they are the future medical practitioners. To assess the pattern of self-medication practice among undergraduate medical students. Tertiary care medical college in West Bengal, India. A cross-sectional questionnaire-based study was conducted among the undergraduate medical students. Out of 500 students of the institute, 482 consented for the study and filled in the supplied questionnaire. Fourteen incomplete questionnaires were excluded and the remaining 468 analyzed. It was found that 267 (57.05%) respondents practiced self-medication. The principal morbidities for seeking self-medication included cough and common cold as reported by 94 students (35.21%) followed by diarrhea (68 students) (25.47%), fever (42 students) (15.73%), headache (40 students) (14.98%) and pain abdomen due to heartburn/ peptic ulcer (23 students) (8.61%). Drugs/ drug groups commonly used for self-medication included antibiotics (31.09%) followed by analgesics (23.21%), antipyretics (17.98%), antiulcer agents (8.99%), cough suppressant (7.87%), multivitamins (6.37%) and antihelminthics (4.49%). Among reasons for seeking self-medication, 126 students (47.19%) felt that their illness was mild while 76 (28.46%) preferred as it is time-saving. About 42 students (15.73%) cited cost-effectiveness as the primary reason while 23 (8.62%) preferred because of urgency. Our study shows that self-medication is widely practiced among students of the institute. In this situation, faculties should create awareness and educate their students regarding advantages and disadvantages of self-medication.

    The goal of the present study was to analyze the prevalence of pain medication prescriptions in general practices in France, Germany, and the UK. This study included all patients aged ≥18 years followed in 2016 in general practitioner practices in France, Germany and the UK. The primary outcome was the prevalence of patients receiving prescriptions for pain medications in France, Germany, and the UK in 2016. The following drugs were included in the analysis: anti-inflammatory and antirheumatic products, non-steroids and analgesics including opioids, antimigraine preparations, and other analgesics and antipyretics. Demographic variables included age and gender. This study included 4,270,142 patients. The prevalences of pain medication prescriptions were 57.3% in France, 29.6% in Germany, and 21.7% in the UK. Although this prevalence generally remained consistent between age groups in France (54.3%-60.3%), it increased with age in Germany (18-30 years: 23.8%; >70 years: 35.8%) and in the UK (18-30 years: 9.3%; >70 years: 43.8%). Finally, the prevalence of pain medication prescriptions was higher in women than in men in all three countries. Paracetamol was prescribed to 82.3% and 60.1% of patients receiving pain medication in France and the UK, respectively, whereas ibuprofen was prescribed to 46.5% of individuals in Germany. The prevalence of pain medication prescriptions was higher in France than in Germany and the UK. Further research is needed to gain a better understanding of the differences in the prescription patterns between these three European countries.

    Update of Acute Ischaemic Stroke Treatment Guidelines of the Spanish Neurological Society based on a critical review of the literature. Recommendations are made based on levels of evidence from published data and studies. Organized systems of care should be implemented to ensure access to the optimal management of all acute stroke patients in stroke units. Standard of care should include treatment of blood pressure (should only be treated if values are over 185/105 mmHg), treatment of hyperglycaemia over 155 mg/dl, and treatment of body temperature with antipyretic drugs if it rises above 37.5 °C. Neurological and systemic complications must be prevented and promptly treated. Decompressive hemicraniectomy should be considered in cases of malignant cerebral oedema. Intravenous thrombolysis with rtPA should be administered within 4.5 hours from symptom onset, except when there are contraindications. Intra-arterial pharmacological thrombolysis can be considered within 6 hours, and mechanical thrombectomy within 8 hours from onset, for anterior circulation strokes, while a wider window of opportunity up to 12-24 hours is feasible for posterior strokes. There is not enough evidence to recommend routine use of the so called neuroprotective drugs. Anticoagulation should be administered to patients with cerebral vein thrombosis. Rehabilitation should be started as early as possible. Treatment of acute ischaemic stroke includes management of patients in stroke units. Systemic thrombolysis should be considered within 4.5 hours from symptom onset. Intra-arterial approaches with a wider window of opportunity can be an option in certain cases. Protective and restorative therapies are being investigated. Copyright © 2011 Sociedad Española de Neurología. Published by Elsevier Espana. All rights reserved.

    Lyme disease is an infection that is estimated to affect over 300,000 people in the United States annually. Typically, it presents with erythema migrans (EM), an annular rash at the site of tick attachment, within 3 to 30 days of inoculation. Untreated patients may progress to early disseminated disease. A further complication, Lyme carditis is rare but may occur several weeks later. It commonly manifests as a variable atrioventricular (AV) conduction block, with a high-grade AV block occurring in only 1% of untreated patients. This case demonstrates an unusually early presentation of Lyme carditis with complete heart block. A 21-year-old male was transferred from an outside emergency department (ED) for possible pacemaker placement due to symptomatic third-degree AV block. Four days earlier the patient presented to the outside ED with fever, chills, and unrecognized EM on his right neck. He was discharged with antipyretics, but no antibiotic therapy. On the day of transfer, he returned with persistent fevers, EM now on his trunk and upper extremities, lightheadedness, and substernal chest pressure. An electrocardiogram revealed the third-degree AV block leading to transfer. Upon arrival, the patient was promptly diagnosed with Lyme carditis. Pacemaker implantation was deferred, and intravenous (IV) ceftriaxone was initiated. Within 48 hours his third-degree AV block improved to a first-degree block. By this time, his EM had also resolved. He was discharged with oral doxycycline and a 30-day event monitor, which ultimately showed persistent first-degree AV block. This case reinforces a unique presentation of Lyme carditis. Disseminated EM and Lyme carditis may present concurrently within 2 weeks of tick attachment. Early recognition and treatment is important for preventing progression to disseminated infection. Lyme-associated AV block will reverse within 48 to 72 hours of initiating IV antibiotic therapy and will not require pacemaker implantation. Lyme carditis

    [6]-Shogaol is a major bioactive component of Zingiber officinale. Although [6]-shogaol has a number of pharmacological activities including antipyretic, analgesic, antitussive and anti-inflammatory effects, the specific mechanisms of its anti-allergic effects have not been studied. In this study, we present the effects of [6]-shogaol on mast cell-mediated allergic reactions in vivo and in vitro. Sprague-Dawley rats received intradermal injections of anti-DNP IgE was injected into dorsal skin sites. After 48 h, [6]-shogaol was administered orally 1 h prior to challenge with DNP-HSA in saline containing 4% Evans blue through the dorsal vein of the penis. In addition, rat peritoneal mast cells (RPMCs) were cultured and purified to investigate histamine release. In vitro, we evaluated the regulatory effects of [6]-shogaol on the level of inflammatory mediators in phorbol 12-myristate 13-acetate plus calcium ionomycin A23187-stimulated human mast cells (HMC-1). [6]-Shogaol reduced the passive cutaneous anaphylaxis reaction compared to the control group, and histamine release decreased significantly following the treatment of RPMCs with [6]-shogaol. In HMC-1 cells, [6]-shogaol inhibited the production of TNF-α, IL-6 and IL-8, as well as the activation of nuclear factor-κB (NF-κB) and phosphorylation of JNK in compound 48/80-induced HMC-1 cells. [6]-shogaol inhibited mast cell-mediated allergic reactions by inhibiting the release of histamine and the production of proinflammatory cytokines with the involvement of regulation of NF-κB and phosphorylation of JNK.

    Viral oral ulcers are common presentations in pediatric clinics. Although self-limiting, painful ulcerative lesions and inflamed mucosa can decrease oral intake and lead to dehydration. Despite the widespread use of Chinese herbal medicine (CHM) for pediatric upper respiratory disease in Taiwan, there is little evidence for its effectiveness as an antipyretic or in aiding ulcer healing for children with viral oral ulcers. We report two cases of children who presented with viral oral ulcers to illustrate the potential efficacy of CHM treatment in recovery from herpangina (HA) and herpetic gingivostomatitis (HGS). A 10-year-old girl with HA presented with an acute febrile illness associated with small vesicular or ulcerative lesions on the posterior oropharyngeal structures. The family refused western medicine due to a prior anaphylactic skin rash when she had taken sulfa drugs. The other patient was a 4-year-old boy with complaints of painful ulcers and hemorrhagic crusts on the lips. He was diagnosed with HGS and had received ibuprofen and supportive treatments such as hydration and local anesthesia spray for days, characterized by fever, anorexia, and nausea to no effect. Because the patients were suffering from the damp-heat syndrome according to Traditional Chinese Medicine (TCM) differentiation, both were treated using the same herbal formulas powder prescription, named Liang Ge San (LGS) and Gan Lu Xiao Du Dan (GLXDD). After several days of CHM treatment, the oral ulcers were in regression. Follow-up of the frontal view in both patients showed satisfactory disappearance of the sick furred tongue. The results of these case reports show that the early prescription of CHM is an effective modality of alternative treatment for viral oral ulcers. To our knowledge, this is the first report of CHM treatment hastening the recovery from febrile disease with viral oral ulcers in Taiwan. Future experimental studies to determine the definitive mechanism and clinical trials

    Self-medication is widely practiced with varying dimensions in India. This practice has many implications, especially among medical and paramedical students having some knowledge and good exposure to drugs. We conducted a two-period observational study to evaluate the change in knowledge and practice of self-medication, over 5 years of time period, among medical and paramedical students from different parts of India. A structured questionnaire was administered to medical (MBBS), dental (BDS), and paramedical students, who come to attend pan India annual cultural, literary, and sports event at New Delhi. The study was conducted in two phases (2007 and 2012) in different respondents of same categories (medical and paramedical) of students. Three-hundred and thirty students from 39 colleges in 2007 and 356 students from 38 colleges in 2012 participated in the study. The prevalence of self-medication remained high in both 2007 and 2012 (74.6% and 69.4%), although no significant difference was observed between the two phases (P = 0.14%). Oral antibacterial agents, oral anti-inflammatory agents, and antipyretics were the most common group of drugs used in both phases of study. A significant increase was observed in number of students who took complete course of oral antibiotics (28.3-38.3%, P = 0.01). The prevalence of self-medication among undergraduate students remains unaltered over the span of 5 years. Nevertheless, there was a better sensitization toward appropriate antibiotic usage and the practice of responsible self-medication needs to be promoted among future healthcare providers.

    Full Text Available Abstract Background Gastrointestinal (GI symptoms, such as diarrhea, vomiting, abdominal pain and nausea are not an uncommon manifestation of an acute respiratory infection (ARI. We therefore evaluated clinical and microbiological factors associated with the presence of GI symptoms in patients consulting a general practitioner (GP for ARI. Methods Nasopharyngeal swabs, stool specimens and clinical data from patients presenting to GPs with an ARI were prospectively collected during two winter seasons (2014-2016. Samples were tested by quantitative real-time PCR for 12 respiratory pathogen groups and for 12 enteric pathogens. Results Two hundred and four of 331 included patients (61.6% were positive for at least one respiratory pathogen. Sixty-nine stools (20.8% were positive for at least one pathogen (respiratory and/or enteric. GI symptoms were more likely declared in case of laboratory confirmed-enteric infection (adjusted odds ratio (aOR = 3.2; 95% confidence interval [CI] [1.2–9.9]; p = 0.02 or human coronavirus (HCoV infection (aOR = 2.7; [1.2–6.8]; p = 0.02. Consumption of antipyretic medication before the consultation seemed to reduce the risk of developing GI symptoms for patients with laboratory-confirmed influenza (aOR = 0.3; [0.1–0.6]; p = 0.002. Conclusions The presence of GI symptoms in ARI patients could not be explained by the detection of respiratory pathogens in stools. However, the detection of enteric pathogens in stool samples could explained by the presence of GI symptoms in some of ARI cases. The biological mechanisms explaining the association between the presence of HCoVs in nasopharynx and GI symptoms need to be explored.

    Ultraviolet (UV) radiation has been reported to induce cutaneous inflammation such as erythema and edema via induction of proinflammatory enzymes and mediators. Sargassum fulvellum is a brown alga of Sargassaceae family which has been demonstrated to exhibit antipyretic, analgesic, antiedema, antioxidant, antitumor, fibrinolytic, and hepatoprotective activities. The purpose of this study is to investigate anti-inflammatory effects of ethylacetate fraction of ethanol extract of Sargassum fulvellum (SFE-EtOAc) in HaCaT keratinocytes and BALB/c mice. In HaCaT cells, SFE-EtOAc effectively inhibited UVB-induced cytotoxicity (60 mJ/cm2) and the expression of proinflammatory proteins such as cyclooxygenase-2 (COX-2), tumor necrosis factor-α (TNF-α), and inducible nitric oxide synthase (iNOS). Furthermore, SFE-EtOAc significantly reduced UVB-induced production of proinflammatory mediators including prostaglandin E2 (PGE2) and nitric oxide (NO). In BALB/c mice, topical application of SFE-EtOAc prior to UVB irradiation (200 mJ/cm2) effectively suppressed the UVB-induced protein expression of COX-2, iNOS, and TNF-α and subsequently attenuated generation of PGE2 and NO as well. In another experiment, SFE-EtOAc pretreatment suppressed UVB-induced reactive oxygen species production and exhibited an antioxidant potential by upregulation of antioxidant enzymes such as catalase and Cu/Zn-superoxide dismutase in HaCaT cells. These results suggest that SFE-EtOAc could be an effective anti-inflammatory agent protecting against UVB irradiation-induced skin damages. PMID:23935680

    Cardamine diphylla (Michx.) A. Wood, commonly called toothwort, is a spring perennial herb belonging to the Brassicaceae family. This endemic plant of Eastern North America has been widely used by multiple American First Nations (i.e. indigenous people of North America) for food and medicine for centuries. The aim of the review is to describe the botany, ethnopharmacology, phytochemistry, and bioactivity of Cardamine diphylla. The review covers literature on Cardamine diphylla, and the alternative name Dentaria diphylla, from English and French language sources. Multiple traditional uses of Cardamine diphylla by American First Nations are well documented. Initial health studies showed that the tested concentrations of the extract were not toxic against brine shrimp larvae and the same extract had a weak free-radical scavenging activity. However, bioactive compounds in the form of aliphatic and indole glucosinolates and some indole alkaloids have been isolated from this plant. Ecological research regarding Cardamine diphylla-insect interactions (such as feeding and oviposition) is also available in the literature. The wide range of traditional uses by multiple American First Nations suggests that the antibacterial, antiviral, immunostimulant, analgesic, antipyretic, and anti-inflammatory activities of this plant should be explored in in vitro and in vivo tests. Traditional modes of preparation of the plant suggest that some of the medicinal properties could certainly be attributed to glucosinolate degradation products (i.e. isothiocyanates), but a clear assignment of active molecules and mechanisms of action remain to be elucidated. The presence of glucosinolates indicates that the plant could be probed for cancer chemopreventive properties. Overall, the review shows that more investigation is necessary to determine the possible benefits of Cardamine diphylla extracts to pharmaceutical companies as a nutraceutic specialty phytotherapeutic agent against respiratory

    Highlights: • TiO 2 and graphite oxide were used as precursors of titanium dioxide nanotubes and graphene respectively. Titanium dioxide nanotube and graphene (GR-TNT) nanocomposites were synthesized through a simple hydrothermal method. • And its application to removal acetaminophen, degradation efficiency is more than 96%. • The photocatalytic degradation results indicated that the sample with 5% GO in GR-TNT nanocomposites for 3 h had the highest degradation rate. • The degradation intermediates of acetaminophen by the composites were invested by GC-MS and the possible pathways were invested. - Abstract: Acetaminophen is commonly used as an antipyretic or analgesics agent and poses threat to human health. In this research, TiO 2 and graphite oxide were used as precursors of titanium dioxide nanotubes and graphene respectively. Titanium dioxide nanotube and graphene (GR-TNT) nanocomposites were synthesized through a hydrothermal method. FT-IR, UV-Vis, XRD, and TGA were used to characterize the catalysts. The acetaminophen degradation rate can reach up to 96% under UV light irradiation for 3 h and with the 5% GR-TNT dosage of 0.1 g L −1 . Further experiments were done to probe the mechanism of the photocatalytic reaction catalyzed by the GR-TNT composite. EDTA (hole scavengers) and t-BuOH (radical scavengers) were used to detect the main active oxidative species in the system. The results showed that the holes are the main oxidation species in the photocatalytic process. This study provides a new prospect for acetaminophen degradation by using high efficiency catalysts

    Introduction Pediatric poisonings represent a major and preventable cause of morbidity and mortality throughout the world. Epidemiologic information about poisoning among children in many lower- and middle-income countries is scarce. This study describes the epidemiology of acute poisonings in children presenting to Ain Shams University's Poisoning Treatment Center (ASU-PTC) in Cairo and determines the causative agents and characteristics of acute poisoning in several pediatric age groups. Methods This retrospective study involved acutely poisoned patients, 0 to 18 years of age, who presented to the ASU-PTC between 1/1/2009 and 12/31/2013. Data were extracted from electronic records maintained by the ASU-PTC. Collected data included demographics, substance of exposure, circumstances of the poisoning, patient disposition, and outcome. Results During the 5-year study period, 38,470 patients meeting our criteria were treated by the ASU-PTC; 19,987 (52%) were younger than 6 years of age; 4,196 (11%) were 6 to 12 years; and 14,287 (37%) were >12 years. Unintentional poisoning accounted for 68.5% of the ingestions, though among adolescents 84.1% of ingestions were with self-harm intent. In all age groups, the most frequent causative drugs were non-opioid analgesics, antipyretics, and antirheumatics. The most common nonpharmaceutical agents were corrosives in preschool children and pesticides in adolescents. Most patients had no/minor effects (29,174 [75.8%]); hospitalization rates were highest among adolescents. There were 119 deaths (case fatality rate of 0.3), primarily from pesticide ingestion. Conclusion Poisoning in preschool children is mainly unintentional and commonly due to nonpharmaceutical agents while poisoning in adolescents is mainly intentional (self-harm). Pesticides, mainly organophosphorous compounds and carbamates, were the most frequent agent leading to morbidity and mortality. PMID:26653953

    The phenomenon of stupefying by the use of available over-the-counter drugs (OTC) among adolescents is an essential problem in both Poland and throughout the world. Popular analgesics, cold medicine and antihistamines contain psychedelic substances, such as dextromethorphan (DXM), pseudoephedrine/ephedrine, codeine (methylmorphine), dimenhydrinate, paracetamol (acetaminophren) and others. Cases of fatal addiction to dextromethorphan, one of the active substances contained in medicines, e.g., the common cold, have been reported. The test results cited by the authors clearly indicate that the use of OTC drugs, whose turnover is not controlled is a domain of females. The extent of use of drugs not prescribed by a doctor has remained for many years at a constant level. The most common poisonings with OTC drugs are caused by those that affect the respiratory system or exert analgesic or antipyretic effects. They are also used in attempted suicides, especially among females. Analyzing poisonings caused by OTC medications their seasonality has been observed. Their number increases during spring-autumn. A territorial differentiation in areas of OTC drug trade in terms of their quantities, with the predominance of southern regions is also noted. Intoxication with psychoactive substances causes the deterioration of relations between young people. In the reviewed studies there is no detailed information on the composition of non-prescription medicines. Moreover, young people have easy access to mushroom fungi, growing in nearby forests and meadows that may have hallucinogenic effects and are available in pharmacies and on the Internet.

    Background: Majority of Indian population is dependent on general practitioners (GPs) for medical services at primary care level in India. They are most preferred and considered to be first contact person for medical services at primary care level. But advances in medical science has put more emphasis on specialist culture and average Bachelor of Medicine and Bachelor of Surgery (MBBS) graduates who are working as general physician are gradually feeling themselves less competent because they are less exposed to latest advances in treatment of diseases. Amidst such scenario, Christian Medical College (CMC) has come up with an idea: “The refer less and resolve more initiative”. It has started a decentralized 2-year family medicine distance diploma course (Postgraduate Diploma in Family Medicine (PGDFM)) now accredited by Dr. MGR Medical University, Chennai, Tamil Nadu, that trains the GPs to become family medicine specialist. Materials and Methods: As component of PGDFM course, this study was conducted to provide better understanding of prevalent ailments and common treatment provided by the GPs in the community at present giving key insight of current practice in rural area by a registered family medicine practitioner. Results: As part of study, among 500 patients evaluated, three most common diagnosis were upper respiratory infections (URIs; 18%), acute gastroenteritis including water-borne diseases (15.8%), and anemia (10.4%). Treatment given to these patients comprised of mostly of antipyretic, analgesic, and antimicrobial agents. Most common drug prescribed was paracetamol for fever. Other common drugs prescribed were amoxicillin/clavulanic acid, chloroquine, artemisin derivative, doxycycline, co-trimoxazole, miltefosine, cephalexin, ceftriaxone sodium, cefixime, oral rehydration salts, ranitidine, omeprazole, pantoprazole, metronidazole, albendazole, ondansetron, diclofenac sodium, piroxicam, ibuprofen, diphenhydramine, codeine-sulfate, amlodipine, ramipril

    Full Text Available Objectives: To evaluate the perceptions and extent of practicing self-medication among undergraduate pharmacy students. Methods: This cross-sectional, questionnaire-based study was conducted over a six month period (January to June 2016 among undergraduate pharmacy students in five reputable public universities of Bangladesh. It involved face-to-face interviews regarding self-medication of 250 respondents selected by simple random sampling. Results: Self-medication was reported by 88.0% of students. Antipyretics (58.40% were mostly preferred for the treatment of fever and headaches. The major cause for self-medication was minor illness (59.60%, p = 0.73 while previous prescriptions were the main source of knowledge as well as the major factor (52.80%, p = 0.94 dominating the self-medication practice. The results also demonstrated 88.80% of students had previous knowledge on self-medication and 83.60% of students always checked the information on the label; mainly the expiry date before use (85.60%. A significant (p < 0.05 portion of the students (51% male and 43% female perceived it was an acceptable practice as they considered self-medication to be a segment of self-care. Furthermore, students demonstrated differences in their response level towards the adverse effect of drugs, the health hazard by a higher dose of drug, a physician’s help in case of side effects, taking medicine without proper knowledge, and stopping selling medicine without prescription. Conclusions: Self-medication was commonly used among pharmacy students primarily for minor illnesses using over-the-counter medications. Although it is an inevitable practice for them it should be considered an important public health problem as this practice may increase the misuse or irrational use of medicines.

    Full Text Available Abstract Background: Retrograde transport to the alpha motoneurons causes spinal degeneration. The neurotrophic factor (NT3 increases the number of myelinated axons in the dorsal root, leads to differentiation and survival of sensory neurons, parasympathetic motoneurons and prevents cell death. Lavender is a plant in the family Lamiaceae which is reported to have antioxidant, antispasmodic, diuretic, anti-asthmatic, refrigerant, and antipyretic effects. This study examined NT3 gene expression changes after sciatic nerve compression in rats, in the presence of Lavandula officinalis extract. Materials and Methods: Lavender Soxhlet hydroalcoholic extraction was prepared. 36 male Wistar rats were randomly divided into 3 groups including control, compression and treatment (compression group + hydroalcoholic extract of Lavender injections 75mg/kg groups. In controls the muscle was opened without damage to gain access to the sciatic nerve. In compression and treatment groups, the sciatic nerve (right leg was compressed. The extract was injected intraperitoneally in two occasions. A biopsy was taken from the spinal cord segments L4-L6 on day 28, total RNA was extracted and cDNA was synthesized and NT3 gene expression changes were analyzed by ANOVA test by using SPSS software. Results: The results showed that NT3 gene expression had a significant reduction in compression group compared to the control group (p<0.001 and it had a significant increase in treatment group compared with the compression group (p<0.001. Conclusion: A significant increase in gene expression shows that Lavandula officinalis hydroalcoholic extract improves nerve regeneration via NT3 gene expression.

    Full Text Available Acetaminophen, the major active metabolite of acetanilide in man, has become one of the most popular over-the-counter analgesic and antipyretic agents, consumed by millions of people daily. However, its mechanism of action is still a matter of debate. We have previously shown that acetaminophen is further metabolized to N-(4-hydroxyphenyl-5Z,8Z,11Z,14Z -eicosatetraenamide (AM404 by fatty acid amide hydrolase (FAAH in the rat and mouse brain and that this metabolite is a potent activator of transient receptor potential vanilloid 1 (TRPV(1 in vitro. Pharmacological activation of TRPV(1 in the midbrain periaqueductal gray elicits antinociception in rats. It is therefore possible that activation of TRPV(1 in the brain contributes to the analgesic effect of acetaminophen.Here we show that the antinociceptive effect of acetaminophen at an oral dose lacking hypolocomotor activity is absent in FAAH and TRPV(1 knockout mice in the formalin, tail immersion and von Frey tests. This dose of acetaminophen did not affect the global brain contents of prostaglandin E(2 (PGE(2 and endocannabinoids. Intracerebroventricular injection of AM404 produced a TRPV(1-mediated antinociceptive effect in the mouse formalin test. Pharmacological inhibition of TRPV(1 in the brain by intracerebroventricular capsazepine injection abolished the antinociceptive effect of oral acetaminophen in the same test.This study shows that TRPV(1 in brain is involved in the antinociceptive action of acetaminophen and provides a strategy for developing central nervous system active oral analgesics based on the coexpression of FAAH and TRPV(1 in the brain.

    N-acetyl-p-aminophenol (APAP, acetaminophen, paracetamol) is a widely used analgesic/antipyretic with weak inhibitory effects on cyclooxygenase (COX) compared to non-steroidal anti-inflammatory drugs (NSAIDs). The mechanism of action of APAP is mediated by its metabolite that activates transient receptor potential channels, including transient receptor potential vanilloid 1 (TRPV1) and TRP ankyrin 1 (TRPA1) or the cannabinoid receptor type 1 (CB1). However, the exact molecular mechanism and target underlying the cellular actions of APAP remain unclear. Therefore, we investigated the effect of APAP on osteoblastic differentiation and cell migration, with a particular focus on TRP channels and CB1. Effects of APAP on osteoblastic differentiation and cell migration of MC3T3-E1, a mouse pre-osteoblast cell line, were assessed by the increase in alkaline phosphatase (ALP) activity, and both wound-healing and transwell-migration assays, respectively. APAP dose-dependently inhibited osteoblastic differentiation, which was well correlated with the effects on COX activity compared with other NSAIDs. In contrast, cell migration was promoted by APAP, and this effect was not correlated with COX inhibition. None of the agonists or antagonists of TRP channels and the CB receptor affected the APAP-induced cell migration, while the effect of APAP on cell migration was abolished by down-regulating TRPV4 gene expression. APAP inhibited osteoblastic differentiation via COX inactivation while it promoted cell migration independently of previously known targets such as COX, TRPV1, TRPA1 channels, and CB receptors, but through the mechanism involving TRPV4. APAP may have still unidentified molecular targets that modify cellular functions. Copyright © 2017 Institute of Pharmacology, Polish Academy of Sciences. Published by Elsevier B.V.

    Alstonia scholaris (L.) R. Br. and Alstonia macrophylla Wall. ex G. Don are two vital medicinal plant species (family: Apocynaceae). In India, the therapeutic use of Alstonia scholaris has been described in both codified and non-codified drug systems for the treatment of malaria, jaundice, gastrointestinal troubles, cancer and in many other ailments. Other species, Alstonia macrophylla has been used in conventional medicines in Thailand, Malaysia and Philippines as a general tonic, aphrodisiac, anticholeric, antidysentery, antipyretic, emmenagogue, and vulnerary agents. In India, Alstonia macrophylla is used as a substitute for Alstonia scholaris in various herbal pharmaceutical preparations. However, one certainly cannot evaluate the truthfulness of a practice (i.e. in scientific terms). In this article we discuss and summarize comparative data about traditional uses, phytochemistry, pharmacology and toxicity of Alstonia scholaris and Alstonia macrophylla. Moreover, in order to unfold future research opportunities, lacunae in the present knowledge are also highlighted. Literature about Alstonia scholaris and Alstonia macrophylla was collected by using electronic and library search. Additionally, referred books on traditional medicine and ethnopharmacology were also utilized for receiving traditional records about both the plant species. Both Alstonia scholaris and Alstonia macrophylla are rich in different types of bioactive alkaloids. So far, broad spectrum of in vitro and in vivo biological and pharmacological activities have been reported to both the species. Amongst them, antimicrobial and anticancer activities were promising. The use of Alstonia macrophylla as a substitute for Alstonia scholaris is not at all justifiable as both the species are distinct from each other in their phytochemistry and pharmacology. Further detail chemical fingerprinting and metabolic studies of these two species are warranted to prevent their mutual adulteration most importantly

    Full Text Available The infectious syndromes associated with arenaviruses in South America are four: febrile syndrome of viral origin; Haemorrhagic fevers with or without neurological involvement; Aseptic meningitis and meningo-encephalitis. Among the Arenavirus of the new world is the Tacaribe complex where the viruses are found: Junín (Argentina, Guanarito (Venezuela, Machupo (Bolivia and Sabiá (Brazil, which are characterized by hemorrhagic fevers. In Colombia the arenavirus Pichindé was isolated in 1965, from the rodent Oryzomys albigularis, in the valley of Pichindé (Valle del Cauca. This arenavirus produces a persistent infection in its host and is not pathogenic for the man. There is evidence of the circulation of the Guanarito virus in rodents from Córdoba, but there are no cases diagnosed in humans; In Colombia, the genome of the lymphocytic choriomeningitis virus was detected in the brains of rodents Mus musculus. The diagnosis is based on the knowledge of local epidemiology and the suspicion of a patient with fever in endemic areas, where infections such as malaria, dengue and leptospirosis, sepsis of bacterial origin and rickectomy have been excluded. Virus isolation in the feverish period is the gold standart, but it implies contact with the virus that is highly infectious, which represents a public health problem. Serology has been used for diagnosis, but there is no commercial evidence and only research groups and large public health laboratories have these tests. Most of the patients present a moderate severity, which needs adequate hydration, antipyretics and anti-inflammatories. All patients with severe signs should be aggressively treated. The use of drugs has not demonstrated a decrease in mortality but a significant reduction in viremia.

    Full Text Available Acetaminophen (APAP is a commonly used analgesic and antipyretic that can cause hepatotoxicity due to production of toxic metabolites via cytochrome P450 (Cyp 1a2 and Cyp2e1. Previous studies have shown conflicting effects of fructose (the major component in Western diet on the susceptibility to APAP-induced hepatotoxicity. To evaluate the role of fructose-supplemented diet in modulating the extent of APAP-induced liver injury, male C57BL/6J mice were given 30% (w/v fructose in water (or regular water for 8 weeks, followed by oral administration of APAP. APAP-induced liver injury (determined by serum levels of liver enzymes was decreased by two-fold in mice pretreated with fructose. Fructose-treated mice exhibited (~1.5 fold higher basal glutathione levels and (~2 fold lower basal (mRNA and activity levels of Cyp1a2 and Cyp2e1, suggesting decreased bioactivation of APAP and increased detoxification of toxic metabolite in fructose-fed mice. Hepatic mRNA expression of heat shock protein 70 was also found increased in fructose-fed mice. Analysis of bacterial 16S rRNA gene amplicons from the cecal samples of vehicle groups showed that the fructose diet altered gut bacterial community, leading to increased α-diversity. The abundance of several bacterial taxa including the genus Anaerostipes was found to be significantly correlated with the levels of hepatic Cyp2e1, Cyp1a2 mRNA, and glutathione. Together, these results suggest that the fructose-supplemented diet decreases APAP-induced liver injury in mice, in part by reducing metabolic activation of APAP and inducing detoxification of toxic metabolites, potentially through altered composition of gut microbiota.

    While performing the Hajj, hajjis face different risks related to the environment, their behaviors and their health conditions that can result in a variety of diseases. The objective of this study was to determine the pattern of diseases among pilgrims seeking medical services in Mina primary health care centers (PHCCs) during the Hajj season in 1429 (2008). This is a descriptive study based on the medical records of a random sample of 4136 patients who attended 13 randomly selected Mina PHCCs from 8 to 12 Dhu-Alhijja, 1429 H (6-10 December 2008). The majority of the patients were men (70.7%), and most of the patients were between 45 and 64 years of age (42.8%). One-fifth (20.2%) of the patients suffered from multiple diseases. Respiratory diseases were the most common (60.8%), followed by musculoskeletal (17.6%), skin (15.0%) and gastrointestinal (13.1%) diseases. Diabetes, asthma and hypertension each constituted less than 3% of the total diseases. Respiratory diseases were the most common independent of nationality or the day of visit, while the frequency of the other diseases varied according to nationality and the day of visit. The most frequently prescribed drugs were analgesics, antipyretics, antibiotics and cough syrups. This study describes the pattern of diseases among pilgrims attending Mina PHCCs, which may aid in providing the best possible health care services to pilgrims.

    Paracetamol, a frequently used antipyretic and analgesic drug, has poor compression moldability owing to its low plasticity. In this study, new co-crystals of paracetamol (PCM) with caffeine (as a co-former) were prepared and delineated. Co-crystals exhibited improved compaction and mechanical behavior. A screening study was performed by utilizing a number of methods namely dry grinding, liquid assisted grinding (LAG), solvent evaporation (SE), and anti-solvent addition using various weight ratios of starting materials. LAG and SE were found successful in the screening study. Powders at 1:1 and 2:1 weight ratio of PCM/CAF by LAG and SE, respectively, resulted in the formation of co-crystals. Samples were characterized by PXRD, DSC, and ATR-FTIR techniques. Compressional properties of PCM and developed co-crystals were analyzed by in-die heckle model. Mean yield pressure (Py), an inverse measure of plasticity, obtained from the heckle plots decreased significantly (p crystals than pure drug. Intrinsic dissolution profile of co-crystals showed up to 2.84-fold faster dissolution than PCM and physical mixtures in phosphate buffer pH 6.8 at 37 °C. In addition, co-crystals formulated into tablets by direct compression method showed better mechanical properties like hardness and tensile strength. In vitro dissolution studies on tablets also showed enhanced dissolution profiles (∼90-97%) in comparison to the tablets of PCM prepared by direct compression (∼55%) and wet granulation (∼85%) methods. In a single dose sheep model study, co-crystals showed up to twofold increase in AUC and C max . A significant (p crystals of PCM were successfully prepared with improved tabletability in vitro and in vivo profile. Enhancement in AUC and C max of PCM by co-crystallization might suggest the dose reduction and avoidance of side effects.

    Cimicifuga racemosa (Actaea racemosa, black cohosh) is used as an anti-inflammatory, antipyretic and analgesic remedy in traditional medicines. The present study focuses on the effects of C. racemosa root extracts on inducible nitric oxide synthase (iNOS) in lipopolysaccharide-stimulated murine macrophages (RAW 264.7). C. racemosa rhizome and phosphate-buffered saline extracts were analysed for phenolcarboxylic acids and triterpene glycosides using an HPLC photodiode array/evaporative light-scattering detector system. iNOS was characterised by measurement of iNOS protein (immunoblotting), iNOS mRNA (semiquantitative competitive RT-PCR), nitric oxide production (nitrite levels) and nuclear translocation of nuclear factor-kappaB (p65 subunit) protein. Incubation of lipopolysaccharide-stimulated macrophages with aqueous C. racemosa extracts (0-6 mg/ml) inhibited nitrite accumulation in a concentration-dependent manner. C. racemosa extracts also reduced iNOS protein expression and iNOS mRNA levels in a dose-dependent manner. C. racemosa extracts did not significantly inhibit iNOS activity and did not affect nuclear translocation of nuclear factor-kappaB (p65 subunit) protein. Incubation with the extract was associated with a concentration-dependent reduction of interferon beta and interferon regulatory factor 1 mRNA. Among the triterpene glycosides, 23-epi-26-deoxyactein was identified as an active principle in C. racemosa extracts. Extracts from the roots of C. racemosa inhibit nitric oxide production by reducing iNOS expression without affecting activity of the enzyme. This might contribute to the anti-inflammatory activities of C. racemosa.

    Full Text Available Abstract Introduction A rare side effect of antipsychotic medication is neuroleptic malignant syndrome, mainly characterized by hyperthermia, altered mental state, haemodynamic dysregulation, elevated serum creatine kinase and rigor. There may be multi-organ dysfunction including renal and hepatic failure as well as serious rhabdomyolysis, acute respiratory distress syndrome and disseminated intravascular coagulation. The prevalence of neuroleptic malignant syndrome is between 0.02% and 2.44% for patients taking neuroleptics and it is not necessary to fulfil all cardinal features characterizing the syndrome to be diagnosed with neuroleptic malignant syndrome. Because of other different life-threatening diseases matching the various clinical findings, the correct diagnosis can sometimes be hard to make. A special problem of intensive care treatment is the management of severe hyperthermia. Lowering of body temperature, however, may be a major clinical problem because hyperthermia in neuroleptic malignant syndrome is typically unresponsive to antipyretic agents while manual cooling proves difficult due to peripheral vasoconstriction. Case presentation A 22-year-old Caucasian man was admitted unconscious with a body temperature of 42°C, elevated serum creatine phosphokinase, tachycardia and hypotonic blood pressure. In addition to intensive care standard therapy for coma and shock, a non-invasive cooling device (Arctic Sun 2000®, Medivance Inc., USA, originally designed to induce mild therapeutic hypothermia in patients after cardiopulmonary resuscitation, was used to lower body temperature. After successful treatment it became possible to obtain information from the patient about his recent ambulant treatment with Olanzapin (Zyprexa® for schizophrenia. Conclusion Numerous case reports have been published about patients who developed neuroleptic malignant syndrome due to Olanzapin (Zyprexa® medication. Frequently hyperthermia has been observed

    Objective: To determine the efficiency of Ribavirin, an anti-viral drug, in patients diagnosed to have CCHF. Patients and Methods: A total of 94 cases were included in the study on high index of suspicion of CCHF. The major criteria of admission were a short history of high-grade fever associated with bleeding from more than one site, i.e., haematemesis, epistaxis etc. the mean age was 34.71 plus minus 12.81 years. All the suspected cases were kept in isolation unit of the hospital and barrier nursing was advised. Results: All the 94 cases were sent to CDC, Atlanta, USA for confirmation and 39 (41.4%) were confirmed to have CCHF. Symptomatic treatment like platelet concentration transfusions, fresh-blood transfusions and antipyretics were given to all cases. Oral Ribavirin was given only to the confirmed cases. It was started in a dose of 2 gm initially, followed by 1 gm 6 hourly for 4 days and then 500 mg 8 hours for 6 days. After a mean period of 2.30 plus minus 0.69 days to treatment with Ribavirin, the clinical as well as the laboratory parameters started improving and returned to normal level after 10 -day course of treatment. Mild anemia and thrombocytosis were seen as adverse effects in some of the patients. Conclusion: For treatment of this fatal disease, we recommended use of oral Ribavirin in all patients diagnosed to have CCHF in the above-mentioned doses, on the basis of our study results.(author)

    Full Text Available Context: Euphorbia pulcherrima (EP belongs to the family: Euphorbiaceae and Genus: Euphorbia. Many species of Euphorbia have been reported as having beneficial properties like anticonvulsive effect, central analgesic properties, antipyretic action, central depressant action and strong sedative effect. However, little study has been done and published on EP. Aims: To observe and evaluate various neuropharmacological effects like antinociceptive effect, anticonvulsant effect, motor in-coordination, pentobarbital induced sleeping time and behavioral responses of EP in mice and rats. Setting and Design: Quantitative experimental study in mice and rats by various experimental models. Materials and Methods: Different experimental models were used to assess the antinociceptive effect (hotplate, tail flick and acetic acid induced writhing test, anticonvulsant effect (Maximal Electroshock Seizure test [MES] and Pentylenetetrazole induced seizures [PTZ], motor in-coordination effect (Rota rod test, pentobarbital induced sleeping time and behavioral responses of EP in mice and rats after oral administration of EP crude dried extracts in three different doses (250, 500 and 1000 mg/kg. Statistical Analysis Used: The significance of difference with respect to control was evaluated using the Mann-Whitney U test. A probability (P-value level less than 0.05 was considered as significant. Results: In MES test model, duration of tonic hind limb extension in mice treated with EP was significantly less as compared to vehicle treated group. EP was most effective in a dose of 1000 mg/kg. There was also significant increase in the latency and decrease in the incidence of convulsions with the use of EP in three different doses in PTZ induced seizure model. Conclusions: This study showed EP (crude dried extracts to possess anticonvulsant properties but no effect on motor co-ordination and anxiety.

    Since 2010, the World Health Organization has been recommending that all suspected cases of malaria be confirmed with parasite-based diagnosis before treatment. These guidelines represent a paradigm shift away from presumptive antimalarial treatment of fever. Malaria rapid diagnostic tests (mRDTs) are central to implementing this policy, intended to target artemisinin-based combination therapies (ACT) to patients with confirmed malaria and to improve management of patients with nonmalarial fevers. The ACT Consortium conducted ten linked studies, eight in sub-Saharan Africa and two in Afghanistan, to evaluate the impact of mRDT introduction on case management across settings that vary in malaria endemicity and healthcare provider type. This synthesis includes 562,368 outpatient encounters (study size range 2,400-432,513). mRDTs were associated with significantly lower ACT prescription (range 8-69% versus 20-100%). Prescribing did not always adhere to malaria test results; in several settings, ACTs were prescribed to more than 30% of test-negative patients or to fewer than 80% of test-positive patients. Either an antimalarial or an antibiotic was prescribed for more than 75% of patients across most settings; lower antimalarial prescription for malaria test-negative patients was partly offset by higher antibiotic prescription. Symptomatic management with antipyretics alone was prescribed for fewer than 25% of patients across all scenarios. In community health worker and private retailer settings, mRDTs increased referral of patients to other providers. This synthesis provides an overview of shifts in case management that may be expected with mRDT introduction and highlights areas of focus to improve design and implementation of future case management programs.

    Full Text Available Nicholas Moore,1 Charles Pollack,2 Paul Butkerait2 1Department of Pharmacology, Université de Bordeaux, Bordeaux, France; 2Pfizer Consumer Healthcare, Madison, NJ, USA Abstract: Nonsteroidal anti-inflammatory drugs (NSAIDs such as ibuprofen have a long history of safe and effective use as both prescription and over-the-counter (OTC analgesics/antipyretics. The mechanism of action of all NSAIDs is through reversible inhibition of cyclooxygenase enzymes. Adverse drug reactions (ADRs including gastrointestinal bleeding as well as cardiovascular and renal effects have been reported with NSAID use. In many cases, ADRs may occur because of drug–drug interactions (DDIs between the NSAID and a concomitant medication. For example, DDIs have been reported when NSAIDs are coadministered with aspirin, alcohol, some antihypertensives, antidepressants, and other commonly used medications. Because of the pharmacologic nature of these interactions, there is a continuum of risk in that the potential for an ADR is dependent on total drug exposure. Therefore, consideration of dose and duration of NSAID use, as well as the type or class of comedication administered, is important when assessing potential risk for ADRs. Safety findings from clinical studies evaluating prescription-strength NSAIDs may not be directly applicable to OTC dosing. Health care providers can be instrumental in educating patients that using OTC NSAIDs at the lowest effective dose for the shortest required duration is vital to balancing efficacy and safety. This review discusses some of the most clinically relevant DDIs reported with NSAIDs based on major sites of ADRs and classes of medication, with a focus on OTC ibuprofen, for which the most data are available.

    Methanesulfonic acid sodium salt (Dipyrone), an antipyretic and analgesic drug, has been demonstrated to improve cerebral ischemia through the inhibition of mitochondrial cell death cascades. The aim of this study was to evaluate the potential photoprotective activity of methanesulfonic acid sodium salt in a model of light-induced retinopathy. One hundred mice were assigned randomly into vehicle (V), methanesulfonic acid sodium salt (D), light damage model plus vehicle (MV) and light damage model plus methanesulfonic acid sodium salt (MD) groups (n = 25 each). In the MD group, methanesulfonic acid sodium salt (100 mg/kg) was administered by intraperitoneal injection 30 minutes before light exposure. Twenty-four hours after light exposure, hematoxylin and eosin staining and transmission electron microscopy (TEM) were used for histological evaluation. The thickness of the outer plus inner-segment and outer nuclear layer was measured on sections parallel to the vertical meridian of the eye at a distance of 1000 mm from the optic nerve. Electroretinography (ERG) test was performed to assess the functional change. The morphology of mitochondria was also revealed by TEM. Finally, the expression of cytochrome c (CytC) and the relative apoptotic proteins were detected by Western blotting, and the interaction between mitochondrial proteins was investigated by co-immunoprecipitation. The photoreceptor inner and outer segments of the MV group were significantly disorganized than the MD group. The thicknesses of the outer plus inner-segment layers and the outer nuclear layer, and the amplitudes of the a and b waves of the scotopic ERG response markedly decreased in the MV group compared to those in the MD group (P light-induced retinopathy through the inhibition of CytC-mediated mitochondrial impairment.

    The stem barks of Zanthoxylum rhoifolium Lam. (Rutaceae), locally known as "mamica de cadela", are popularly used in dyspepsies, stomachic, tonic, antitumoral, antipyretic and are used in treating flatulence and colic. The objective of this study was to evaluate the gastroprotective effect of the ethanolic extract of Zanthoxylum rhoifolium (EEZR) stem barks in acute gastric lesion models, investigating their possible mechanisms. Mice were used for the evaluation of the acute toxicity, and mice and rats to study the gastroprotective activity. The gastroprotective action of EEZR was analyzed in the absolute ethanol, HCl/ethanol and indomethacin-induced gastric lesion models in mice, hypothermic-restraint stress, and ischemia/reperfusion in rats. In the investigation of the gastroprotective mechanisms of EEZR, the participation of the NO-synthase pathway, ATP-sensitive potassium channels (K(ATP)), the levels of the non-protein sulfhydril groups (NP-SH) and the catalase activity using the ethanol-induced gastric mucosa lesion model and the quantification of the gastric mucus and the antisecretory activity through pylorus ligature model in rats were analyzed. The animals did not present any signs of acute toxicity for the EEZR (up to the 4 g/kg dose, po), and it was not possible to calculate the DL(50). EEZR (125-500 mg/kg) exhibited a significant gastroprotective effect in absolute ethanol, HCl/ethanol, hypothermic-restraint stress, and ischemia/reperfusion-induced gastric lesion models. EEZR (250 and 500 mg/kg) exhibited still a gastroprotective activity in the indomethacin-induced ulcer model. Gastroprotection of EEZR was significantly decreased in pre-treated mice with l-NAME or glibenclamide, the respective nitric oxide synthase and K(ATP) channels inhibitors. Our studies revealed that EEZR (500 mg/kg) prevented the decrease of the non-protein sulfhydril groups (NP-SH) and increased the catalase levels in ethanol-treated animals. Furthermore, the extract (500 mg

    Centaurium erythraea Rafn (CE) is a traditional medicinal herb in Serbia with antidiabetic, digestive, antipyretic and antiflatulent effects AIM OF THE STUDY: To investigate the potential protective effects of the methanol extract of the aerial parts of CE against glyco-oxidative stress in red blood cells (RBCs) in rats with experimentally induced diabetes. Diabetes was induced in Wistar rats by intraperitoneal (i.p.) injection of multiple low-dose streptozotocin (STZ) (40mg/kg, for five consecutive days), with the 1st day after the last STZ injection taken as the day of diabetes onset. The methanol extract of CE (100mg/kg) was administered orally and daily, two weeks before the first STZ injection, during the 5-day treatment with STZ, and for four weeks after the STZ injections (pre-treated group) or for four weeks after diabetes onset (post-treated group). The effect of CE extract administration on the redox status of RBCs was evaluated by assessing lipid peroxidation, the ratio of reduced/oxidized glutathione (GSH/GSSG), the level of S-glutathionylated proteins (GSSP) and the enzymatic activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione reductase (GR) in RBCs four weeks after diabetes onset. The major biochemical parameters of diabetes, protein glycation/glycosylation of erythrocytes and parameters which correlate with their aggregation and deformability were also evaluated. Daily application of CE extract to STZ-induced diabetic rats provided important antidiabetic effects, observed in both pre-treated and post-treated groups of diabetic rats as elevated serum insulin concentration, reduction of blood glucose and glycated hemoglobin concentrations and an improved lipid profile. Antioxidant effects of CE extract were detected in RBCs of diabetic rats and observed as decreased lipid peroxidation and ameliorated oxidative damage as a result of increased SOD, CAT and GR activities, an improved GSH/GSSG ratio and

    To determine the relative bioavailability and plasma paracetamol concentration profiles following administration of a proprietary formulation of paracetamol suppositories to postoperative children. Study A-eight children undergoing minor surgery had blood samples collected following the rectal administration of either a 250 mg or 500 mg paracetamol suppository on one day and an equivalent oral dose on the following day. A mean dose of 13 mg/kg gave a mean Cmax (Tmax) of 7.7 mg/L (1.6 h) and 4.9 mg/L (2.0 h) following oral and rectal administration, respectively. The mean relative rectal bioavailability was 78% (95% confidence interval of 55-101%). Study B-20 children undergoing tonsillectomy and/or adenoidectomy were randomly assigned to receive a postoperative dose of 500 mg of paracetamol either as 2 x 250 mg liquid filled or 1 x 500 mg hard wax Panadol suppository. A mean dose of 25 mg/kg produced mean maximum plasma paracetamol concentrations of 13.2 mg/L and 14.5 mg/L at 2.1 and 1.9 h for the hard and liquid filled suppository, respectively. The absorption rate constants and areas under the curves suggested no difference in the rate or extent of absorption between the two formulations. Absorption of paracetamol following rectal administration of Panadol suppositories to postoperative children is slower and reduced as compared to oral therapy. The hard wax and liquid filled products have similar absorption characteristics. The usually quoted antipyretic therapeutic range for paracetamol is 10-20 mg/L, although 5 mg/L may be effective. A single rectal dose of 25 mg/kg will obtain this lower concentration within 1 h of administration and maintain it for up to 6 h. When given in an appropriate dose for analgesia, maximum plasma paracetamol concentrations would be available in the immediate postoperative period if the rectal dose was given 2 h before the planned end of the procedure.

    To characterize the use of medicines by patients of the primary health care of the Brazilian Unified Health System (SUS). This is a cross-sectional, exploratory, and descriptive study, part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015). Interviews were carried out with patients present in the services by semi-structured questionnaires. Sociodemographic, clinical, and use of medicines variables were assessed and the use of medicines in the 30 days prior to the interview was also verified. The population was stratified into three age groups: 18 to 44, 45 to 64, and 65 years or more. The differences between the age groups were verified using the Student's t-test for continuous variables and chi-square test for the categorical ones. The complex samples analysis plan was employed. The medicines were classified according to the Anatomical Therapeutic Chemical Classification System. Of the 8,803 patients interviewed, 6,511 (76.2%) reported to have used medicines in the 30 days prior to the interview. On average, each patient used 2.32 medicines, without difference between the sexes. Among medicine users, 18.2% were aged 65 years or more. Compared to the other age groups, older adults presented more comorbidities, used more medicines, and self-reported worse health conditions. They were also less educated, reported worse economic situation, and lived alone. The medicines that were mostly used were "other analgesics and antipyretics" (3rd ATC level) and Losartan (5th ATC level). Most medicine users had lower education level and presented comorbidities. The most used medicines were the antihypertensive ones. Self-medication was higher among young people. Most patients reported to use generic medicines. The average number of medicines and the prevalence of use increased with age. Due to the characteristics
