    Full Text Available Furosemide is the diuretic most used in newborn infants. It blocks the Na+-K+-2Cl− symporter in the thick ascending limb of the loop of Henle increasing urinary excretion of Na+ and Cl−. This article aimed to review the published data on the clinical pharmacology of furosemide in neonates to provide a critical, comprehensive, authoritative and, updated survey on the metabolism, pharmacokinetics, pharmacodynamics and side-effects of furosemide in neonates. The bibliographic search was performed using PubMed and EMBASE databases as search engines; January 2013 was the cutoff point. Furosemide half-life (t1/2 is 6 to 20-fold longer, clearance (Cl is 1.2 to 14-fold smaller and volume of distribution (Vd is 1.3 to 6-fold larger than the adult values. t1/2 shortens and Cl increases as the neonatal maturation proceeds. Continuous intravenous infusion of furosemide yields more controlled diuresis than the intermittent intravenous infusion. Furosemide may be administered by inhalation to infants with chronic lung disease to improve pulmonary mechanics. Furosemide stimulates prostaglandin E2 synthesis, a potent dilator of the patent ductus arteriosus, and the administration of furosemide to any preterm infants should be carefully weighed against the risk of precipitation of a symptomatic patent ductus arteriosus. Infants with low birthweight treated with chronic furosemide are at risk for the development of intra-renal calcifications.

    Long-term anticoagulation treatment with warfarin has been associated with a number of limitations in clinical practice and there is a need for more convenient long-term anticoagulation treatment. One of the non-vitamin K oral anticoagulants in development is edoxaban, a factor Xa inhibitor that is administered once daily. The pharmacological properties of edoxaban have various advantages in anticoagulant therapy. Edoxaban quickly reaches peak plasma concentrations in 1.5 h, has a half-life of 10-14 h, has relatively high bioavailability of 62% and exhibits highly selective, competitive, concentration-dependent inhibition of human factor Xa. The plasma concentrations of edoxaban are also closely correlated with suppression of thrombin generation and a range of platelet activation parameters (fragment 1+2, thrombin-antithrombin complex, and β-thromboglobulin), which edoxaban has been shown to rapidly inhibit. The anticoagulant activity of edoxaban is not affected by food intake or ethnicity and a number of drug-drug interaction studies have been performed. Co-administration of edoxaban with strong P-glycoprotein inhibitors, such as dronedarone, quinidine, and verapamil requires edoxaban dose-reduction by 50% to avoid the risk of over-exposure. The exposure of edoxaban may also increase in patients with a body weight ≤60 kg and moderate renal impairment. This meant a dose-reduction strategy in patients at risk of over-exposure was utilized in Phase III clinical studies. In conclusion, the pharmacological properties of edoxaban provide rapid and specific inhibition of factor Xa, which is closely related to plasma concentrations. Given the limitations with long-term warfarin therapy, once-daily edoxaban may provide a convenient long-term alternative for patients. PMID:24810388

    The role of clinical pharmacology in improving the prevention and treatment of malaria is reviewed. A series of general and specific issues is discussed, concentrating on risk-benefit and cost-effectiveness. The techniques of clinical pharmacokinetics play an important role in the optimal use of drugs and this is illustrated by studies on quinine and proguanil. In discussing amodiaquine toxicity, the role of the pharmacologist and the chemist in designing out drug toxicity lends hope for producing a new generation of antimalarial drugs. PMID:9625927

    Aloe vera L., is a plant used worldwide as folk remedy for the treatment of various ailments, including skin disorders. Its gel is present in cosmetics, medicinal products and food supplements. Psoriasis, an immune-mediated chronic inflammatory disease, involving mainly the skin, affects about the 2-3% of general population. Conventional pharmacological treatments for psoriasis can have limited effectiveness and can cause adverse reactions. For this reason often psoriatic patients look for alternative treatments based on natural products containing Aloe vera. We conducted a systematic review of clinical trials assessing effectiveness and safety of aloe for the treatment of psoriasis. Clinical studies published in English were considered; a total of four clinical trials met inclusion criteria. Studies were also evaluated by using the Jadad scale and Consort Statement in Reporting Clinical trials of Herbal Medicine Intervention. Quality and methodological accuracy of considered studies varied considerably, and some crucial information to reproduce clinical results was missing. We conclude that administration of aloe as cutaneous treatment is generally well tolerated, as no serious side effects were reported. Results on the effectiveness of Aloe vera are contradictory; our analysis reveals the presence of methodological gaps preventing to reach final conclusions. PMID:25756474

    Full Text Available ABSTRACTCarthami flos, the dried floret of Carthamus tinctorius L., Asteraceae (safflower, has been widely used in traditional Chinese medicine to treat a broad range of ailments, such as coronary heart disease, angina pectoris, gynecologic disease, stroke, and hypertension. However, although several studies on Carthami flos have been done consecutively, the results are usually scattered across various documents. This review aims to provide up-to-date information on the traditional uses, pharmacology, clinical applications, and toxicology of Carthami flos in China and thereby to provide a basis for further investigation of its use to treat dissimilar diseases. Various ethnomedical uses of Carthami flos have been documented in many ancient Chinese books. Crude extracts and isolated compounds from Carthami flos show a broad range of pharmacological properties, such as protective effects on brain tissue, on osteoblasts, and in myocardial ischemia, as well as anti-inflammatory, antithrombotic, antitumor, and antidiabetic activities. To date, safflower and safflor yellow injections have been used to treat coronary heart disease, chronic pulmonary heart disease, cerebrovascular diseases, orthopedic diseases, and diabetes mellitus. Regarding the toxicology of Carthami flos, among the side effects that have been observed are allergic reaction, spermatogenetic failure, fatty liver, and nephrotoxicity.

  7. A review on clinical management and pharmacological therapy on hereditary haemorrhagic telangiectasia (HHT).

    2010-07-01

    Hereditary Haemorrhagic Telangiectasia (HHT) or Rendu-Osler-Weber syndrome, is an autosomal dominant rare disease characterized by localized angiodysplasia. This is manifested as epistaxis, mucocutaneous and gastrointestinal telangiectases, and arteriovenous malformations in the pulmonary, cerebral or hepatic circulation. The prevalence is between 1 in 5,000 to 8,000, although it is higher in some regions. The most frequent clinical manifestation of HHT is epistaxis, normally from light to moderate from the 4(th) decade of life. However, many patients show severe epistaxis which may interfere with their quality of life. The epistaxis is due to telangiectasia on the nasal mucosa. These are focally dilated postcapilar venules, which in advanced phases show many layers of smooth muscle cells without elastic fibers, and very frequently directly connect with dilated arterioles. As a consequence of these vascular alterations, telangiectases are very sensitive to slight trauma and even to the friction with the air when breathing, which gives rise to nose bleeds. Unfortunately, there is no optimal pharmacological treatment for the epistaxis in HHT. The use of antifibrinolytic agents for the treatment of HHT has been studied recently by our group as an effective relief for nasal and gastric haemorrhages. This work represents a systematic review and the beginning of a systematic laboratory work we are now conducting in our lab to screen for "orphan drugs" as therapeutic agents in HHT. In this context, the use of hormones, immunosuppresants and anti-angiogenic agents are under preclinical study in our laboratory. PMID:19485912

    Since ancient times, plants and herbal preparations have been used as medicine. Research carried out in the last few decades has verified several such claims. Aloe arborescens Miller, belonging to the Aloe genus (Family Asphodelaceae), is one of the main varieties of Aloe used worldwide. The popularity of the plant in traditional medicine for several ailments (antitumor, immunomodulatory, antiinflammatory, antiulcer, antimicrobial and antifungal activity) focused the investigator's interest on this plant. Most importantly, the reported studies have shown the plant effectiveness on various cancer types such as liver, colon, duodenal, skin, pancreatic, intestinal, lung and kidney types. These multiple biological actions make Aloe an important resource for developing new natural therapies. However, the biological activities of isolated compounds such as glycoprotein, polysaccharides, enzyme and phenolics were insufficient. Considering all these, this contribution provides a systematic review outlining the evidence on the biological efficacy of the plant including the pharmacology and the related mechanisms of action, with specific attention to the various safety precautions, and preclinical and clinical studies, indicating the future research prospects of this plant.

    2010-01-01

    Pharmacological treatment and several drugs of abuse have been associated with ischemic heart disease (IHD) and cerebrovascular diseases (CVD). However, there is a paucity of data on the independent risk of vascular disease (VD) associated with pharmacological treatment and no controlled trials demonstrating a reduction in risk with abstinence. Information about IHD and CVD-related drug abuse is mainly limited to epidemiological studies focused on urban populations. The potential link between some pharmacological treatments (estrogen, some oncologic drugs and some atypical antipsychotics) and cerebrovascular adverse events was analyzed, but disagreement about an association persists. Drugs of abuse, including cocaine, amphetamines and heroin, have been associated with an increased vascular risk. These drugs can cause abrupt changes in blood pressure, vasculitic-type changes, lead to embolization caused by infective endocarditis, and hemostatic and hematologic abnormalities that can result in increased blood viscosity and platelet aggregation. Long-term treatment strategies based on medication, psychological support, and outreach programs play an important role in treatment of drug dependency. In these last years public interest in risk factors for VD has been constantly increasing and the successful identification and management of pharmacological treatment and drug abuse can be challenging. One of the major public health issues for the future will be to focus more on new vascular risk factor recognition and management. The objective of this chapter is to review the relevance of IHD and CVD associated with various pharmacological treatments and drug abuse with focusing on ischemic disease. This chapter reports the clinical evidence of this association and analyzes the experimental role of new drugs as a growing risk factor of VD with the hypothetical new association. In conclusion, in this chapter great attention is paid to evaluating the scientific and real

    Alfaxalone-2-hydroxpropyl-β-cyclodextrin (alfaxalone-HPCD) was first marketed for veterinary use in Australia in 2001 and has since progressively became available throughout the world, including the USA, where in 2012 Food and Drug Administration (FDA) registration was granted. Despite the growing body of published works and increasing global availability of alfaxalone-HPCD, the accumulating evidence for its use in cats has not been thoroughly reviewed. The purpose of this review is: (1) to detail the pharmacokinetic properties of alfaxalone-HPCD in cats; (2) to assess the pharmacodynamic properties of alfaxalone-HPCD, including its cardiovascular, respiratory, central nervous system, neuromuscular, hepatic, renal, haematological, blood-biochemical, analgesic and endocrine effects; and (3) to consider the clinical application of alfaxalone-HPCD for sedation, induction and maintenance of anaesthesia in cats. Based on the published literature, alfaxalone-HPCD provides a good alternative to the existing intravenous anaesthetic options for healthy cats. PMID:25582797

In in vitro and in vivo model systems, curcumin displays potent pharmacological effects, by targeting many critical cellular factors, through a diverse array of mechanisms of action. Despite this tremendous molecular versatility, however, the clinical application of curcumin remains limited due to poor pharmacokinetic characteristics in human beings. The current trend is to develop and utilize unique delivery systems, chemical derivatives, and chemical analogs to circumvent these pharmacological obstacles, in order to optimize the conditions for curcumin as a chemopreventive and chemotherapeutic agent in diseases such as cancer, diabetes, obesity, Alzheimer's disease, and inflammatory disorders. The present work seeks to review recent studies in the basic pharmacological principles and potential clinical applications of curcumin.Keywords: curcumin, pharmacological properties, signal transduction, cellular targets, cancer, inflammation

    Davis, R; Whittington, R; Bryson, H M

    1997-04-01

    Nefazodone hydrochloride is a phenylpiperazine antidepressant with a mechanism of action that is distinct from those of other currently available drugs. It potently and selectively blocks postsynaptic serotonin (5-hydroxytryptamine; 5-HT) 5-HT2A receptors and moderately inhibits serotonin and noradrenaline (norepinephrine) reuptake. In short term clinical trials of 6 or 8 weeks' duration, nefazodone produced clinical improvements that were significantly greater than those with placebo and similar to those achieved with imipramine, and the selective serotonin reuptake inhibitors (SSRIs) fluoxetine, paroxetine and sertraline. The optimum therapeutic dosage of nefazodone appears to be between 300 and 600 mg/day. Limited long term data suggest that nefazodone is effective in preventing relapse of depression in patients treated for up to 1 year. Analyses of pooled clinical trial results indicate that nefazodone and imipramine produces similar and significant improvements on anxiety- and agitation-related rating scales compared with placebo in patients with major depression. Short term tolerability data indicate that nefazodone has a lower incidence of adverse anticholinergic, antihistaminergic and adrenergic effects than imipramine. Compared with SSRIs, nefazodone causes fewer activating symptoms, adverse gastrointestinal effects (nausea, diarrhoea, anorexia) and adverse effects on sexual function, but is associated with more dizziness, dry mouth, constipation, visual disturbances and confusion. Available data also suggest that nefazodone is not associated with abnormal weight gain, seizures, priapism or significant sleep disruption, and appears to be relatively safe in overdosage. Nefazodone inhibits the cytochrome P450 3A4 isoenzyme and thus has the potential to interact with a number of drugs. Further long term and comparative studies will provide a more accurate assessment of the relative place of nefazodone in the management of major depression. Nonetheless

    1974-01-01

    Prostaglandin research has been 1 of the most stimulating features of biomedical investigation in the past decade. Interest developed at a time of expanding knowledge of hormonal and neurohormonal behavior and research work received a tremendous impetus in the early 1960s with the elucidation in Sweden of the chemical structures of prostaglandins, followed by the discovery of their biosynthetic pathways. The original findings of large amounts of prostaglandin in the male accessory genital glands and their secretions, and subsequent discovery in the menstrual and amniotic fluids linked these substances with human production. As a result of further investigation, clinical applications of prostaglandins for the induction of labor and termination of early unwanted pregnancies have been developed. Apart from the functions of the prostaglandins in the reproductive area, they have been shown to have a widespread distribution in the body and produce many different pharmacological effects. Prostaglandins are thought to be involved in the regulation of blood pressure and through their vascular effects have therapeutic potential in the treatment of hypertension and peripheral vascular disease. Through their bronchodilator effect, some prostaglandins may become useful in the treatment of asthma. PMID:4611742

    Angioedema (AE) is a unique clinical presentation of an unchecked release of bradykinin. The origin of this clinical presentation can be either genetic or acquired. The outcome within the patient is subcutaneous swelling of the lower layers of the epidermis. Symptoms are most often localized to the upper airway or the gastrointestinal tract. A typical course resolves in 5 to 7 days, but in some patients, the clinical manifestations exist up to 6 weeks. Hereditary AE is rare and genetically linked, and typically, the patient has episodes for many years before diagnosis. Episodes of acquired AE may be drug induced, triggered by a specific allergen, or idiopathic. Angioedema can elicit the need for critical care interventions, for advanced airway management, or unnecessary abdominal surgery. The treatment for these patients is evolving as new pharmacological agents are developed. This article addresses subtypes of AE, triggers, pharmacology, and information for interdisciplinary team planning of individualized case management. PMID:27258954

    Antman, Elliott; Weiss, Scott; Loscalzo, Joseph

    2012-01-01

    The rapidly growing disciplines of systems biology and network science are now poised to meet the fields of clinical medicine and pharmacology. Principles of systems pharmacology can be applied to drug design and, ultimately, testing in human clinical trials. Rather than focusing exclusively on single drug targets, systems pharmacology examines the holistic response of a phenotype-dependent pathway or pathways to drug perturbation. Knowledge of individual pharmacogenetic profiles further modulates the responses to these drug perturbations, moving the field toward more individualized ('personalized') drug development. The speed with which the information required to assess these system responses and their genomic underpinnings is changing and the importance of identifying the optimal drug or drug combinations for maximal benefit and minimal risk require that clinical trial design strategies be adaptable. In this paper, we review the tenets of adaptive clinical trial design as they may apply to an era of expanding knowledge of systems pharmacology and pharmacogenomics, and clinical trail design in network medicine.

    Chalcones (1,3-diaryl-2-propen-1-ones) and their heterocyclic analogues, belong to the flavonoid family, which possess a number of interesting biological properties such as antioxidant, cytotoxic, anticancer, antimicrobial, antiprotozoal, antiulcer, antihistaminic and anti-inflammatory activities. Several pure chalcones have been approved for clinical use or tested in humans. Clinical trials have shown that these compounds reached reasonable plasma concentration and are well-tolerated. For this reason they are an object of continuously growing interest amongst the scientists. However, much of the pharmacological potential of chalcones is still not utilized. The purpose of this review is to provide an overview of the pharmacological activity of naturally occurring and synthetic chalcones. This review highlights more recent pharmacological screening of these compounds, their mechanisms of action and relevant structure-activity relationships. PMID:22320299

    Age related macular degeneration (AMD) is a pathological aging of the macula, brought about by the interaction of genetic and environmental factors. It induces geographic atrophy of the retina and/or choroidal neovascularization. In the latter, abnormal vessels develop from the choriocapillaris, with the involvement of VEGF (vascular endothelial growth factor). The VEGF family includes several factors, including VEGF-A, B, C, D, F and PlGF (placental growth factor). Their biological properties and their affinities to the VEGFR1, VEGFR2 and VEGFR3 receptors found on endothelial cells differ. Exudative AMD involves mainly VEGF-A and VEGF-R2. Anti-VEGF agents used in ophthalmology (ranibizumab, bevacizumab and aflibercept) are designed to primarily target this pathway. In vitro, all have sufficient affinity to their ligands. Their therapeutic efficacy must therefore be judged based on clinical criteria. In clinical practice, the minimum number of injections required for a satisfactory result appears to be comparable with all the three. The few available studies on therapeutic substitutions of anti-VEGF compounds suggest that some patients may benefit from substituting the anti-VEGF in cases of an unsatisfactory response to an initial molecule. Although local side effects, including increased risk of geographic atrophy, and systemic effects, including vascular accidents, have been suggested, these risks remain low, specially compared to the benefits of the treatment. Differences in safety between anti-VEGF are theoretically possible but unproven. PMID:25190312

    2014-01-01

    Anaphylaxis occurs in the surgical population and may have devastating consequences. Anaphylaxis and anaphylactoid reactions are immediate hypersensitivity reactions that are most commonly precipitated by medications, insect stings, and foods. In the surgical population, 47.4% of immediate hypersensitivity reactions were precipitated by neuromuscular blocking agents, followed by latex and antibiotics in 20% and 18.1% of cases, respectively. Initial treatment consists of removing the precipitating trigger, administering epinephrine, and correct patient positioning. Secondary prevention measures should be instituted to prevent future occurrences. All health care professionals should have an understanding of the clinical presentation and medical management of anaphylaxis to improve patient outcomes. PMID:25461639

    2005-08-01

    This paper reviews the chemistry, pharmacology and clinical properties of Echinacea species used medicinally. The Echinacea species Echinacea angustifolia, Echinacea pallida and Echinacea purpurea have a long history of medicinal use for a variety of conditions, particularly infections, and today echinacea products are among the best-selling herbal preparations in several developed countries. Modern interest in echinacea is focused on its immunomodulatory effects, particularly in the prevention and treatment of upper respiratory tract infections. The chemistry of Echinacea species is well documented, and several groups of constituents, including alkamides and caffeic acid derivatives, are considered important for activity. There are, however, differences in the constituent profile of the three species. Commercial echinacea samples and marketed echinacea products may contain one or more of the three species, and analysis of samples of raw material and products has shown that some do not meet recognized standards for pharmaceutical quality. Evidence from preclinical studies supports some of the traditional and modern uses for echinacea, particularly the reputed immunostimulant (or immunomodulatory) properties. Several, but not all, clinical trials of echinacea preparations have reported effects superior to those of placebo in the prevention and treatment of upper respiratory tract infections. However, evidence of efficacy is not definitive as studies have included different patient groups and tested various different preparations and dosage regimens of echinacea. On the basis of the available limited safety data, echinacea appears to be well tolerated. However, further investigation and surveillance are required to establish the safety profiles of different echinacea preparations. Safety issues include the possibility of allergic reactions, the use of echinacea by patients with autoimmune diseases and the potential for echinacea preparations to interact with

Gastrointestinal symptoms in association with migraine including, nausea, vomiting, and gastroparesis, affect a large proportion of migraine sufferers. These symptoms may result in delays or inconsistencies in the absorption of oral treatments. Hence, the necessity for an innovative, non-invasive, parenteral delivery formulation for quick and effective treatment of migraine attacks is evident. Iontophoresis utilizes minimal amounts of electrical potential to support the fast transfer of ionized medication transdermally and into the general circulation. Two pharmacokinetic clinical trials have shown that iontophoretic delivery of sumatriptan through the skin produces quick and reproducible therapeutic plasma concentrations. A randomized, double-blind, multicenter, phase III study demonstrated superior efficacy versus placebo and excellent tolerability, with no triptan-related adverse events. The proportion of patients that were pain-free at 2 h post-treatment was 18% for the sumatriptan patch vs 9% for placebo (P = 0.0092; number needed to treat = 11.1. Upon approval from the Food and Drug Administration and other regulatory authorities, the iontophoretic transdermal delivery of sumatriptan will be a good choice for patients experiencing poor absorption of oral medication often associated with migraine and/or for those with intolerable triptan-related adverse events.Keywords: iontophoretic patch, migraine, migraine treatment, sumatriptan, transdermal patch

    2016-04-01

    At present, no treatment recommendations can be made for compulsive buying disorder. Recent studies have found evidence for the efficacy of psychotherapeutic options, but less is known regarding the best pharmacologic treatment. The purpose of this review is to present and analyze the available published evidence on the pharmacological treatment of compulsive buying disorder. To achieve this, we conducted a review of studies focusing on the pharmacological treatment of compulsive buying by searching the PubMed/MEDLINE database. Selection criteria were applied, and 21 studies were identified. Pharmacological classes reported included antidepressants, mood stabilizers, opioid antagonists, second-generation antipsychotics, and N-methyl-D-aspartate receptor antagonists. We found only placebo-controlled trials for fluvoxamine; none showed effectiveness against placebo. Three open-label trials reported clinical improvement with citalopram; one was followed by a double-blind discontinuation. Escitalopram was effective in an open-label trial but did not show efficacy in the double-blind phase. Memantine was identified as effective in a pilot open-label study. Fluoxetine, bupropion, nortriptyline, clomipramine, topiramate and naltrexone were only reported to be effective in clinical cases. According to the available literature, there is no evidence to propose a specific pharmacologic agent for compulsive buying disorder. Future research is required for a better understanding of both pathogenesis and treatment of this disorder. PMID:27067344

    The present review is aimed at providing a comprehensive summary on the botany, utility, phytochemistry, pharmacology, and clinical trials of Morus alba (mulberry or sang shu). The mulberry foliage has remained the primary food for silkworms for centuries. Its leaves have also been used as animal feed for livestock and its fruits have been made into a variety of food products. With flavonoids as major constituents, mulberry leaves possess various biological activities, including antioxidant, antimicrobial, skin-whitening, cytotoxic, anti-diabetic, glucosidase inhibition, anti-hyperlipidemic, anti-atherosclerotic, anti-obesity, cardioprotective, and cognitive enhancement activities. Rich in anthocyanins and alkaloids, mulberry fruits have pharmacological properties, such as antioxidant, anti-diabetic, anti-atherosclerotic, anti-obesity, and hepatoprotective activities. The root bark of mulberry, containing flavonoids, alkaloids and stilbenoids, has antimicrobial, skin-whitening, cytotoxic, anti-inflammatory, and anti-hyperlipidemic properties. Other pharmacological properties of M. alba include anti-platelet, anxiolytic, anti-asthmatic, anthelmintic, antidepressant, cardioprotective, and immunomodulatory activities. Clinical trials on the efficiency of M. alba extracts in reducing blood glucose and cholesterol levels and enhancing cognitive ability have been conducted. The phytochemistry and pharmacology of the different parts of the mulberry tree confer its traditional and current uses as fodder, food, cosmetics, and medicine. Overall, M. alba is a multi-functional plant with promising medicinal properties. PMID:26850343

    The dose of a drug is a major determinant of its safety, and establishing a safe dose of a novel drug is a prime objective during clinical development. The design of pre-marketing clinical trials precludes the representation of important subpopulations such as children, the elderly and people with co-morbidities. Therefore, postmarketing surveillance (PMS) activities are required to monitor the safety profile of drugs in real clinical practice. Furthermore, individual variations in pharmacogenetic profiles, the immune system, drug metabolic pathways and drug-drug interactions are also important factors in the occurrence of adverse drug reactions. Thus, the safety of a drug is a major clinical consideration before and after it is marketed. A multidisciplinary approach is required to enhance the safety profile of drugs at all stages of development, including PMS activities. Clinical pharmacology encompasses a range of disciplines and forms the backbone of drug safety consideration during clinical drug development. In this review we give an overview of the clinical drug development process and consider its limitations. We present a discussion of several aspects of clinical pharmacology and their application to enhancing drug safety. Pharmacokinetic-pharmacodynamic modelling provides a method of predicting a clinically safe dose; consideration of drug pharmacokinetics in special populations may enhance safe therapeutics in a wider spectrum of patients, while pharmacogenetics provides the possibility of genotype-specific therapeutics. Pharmacovigilance activities are also discussed. Given the complex nature and unpredictability of type B reactions, PMS activities are crucial in managing the risks drugs pose to the general population. The various aspects of clinical pharmacology discussed make a strong case for this field as the backbone of optimising and promoting safe development and use of drugs. PMID:15154826

    Full Text Available Status epilepticus and acute repetitive seizures still pose a management challenge despite the recent advances in the field of epilepsy. Parenteral formulations of old anticonvulsants are still a cornerstone in acute seizure management and are approved by the FDA. Intravenous levetiracetam, a second generation anticonvulsant, is approved by the FDA as an adjunctive treatment in patients 16 years or older when oral administration is not available. Data have shown that it has a unique mechanism of action, linear pharmacokinetics and no known drug interactions with other anticonvulsants. In this paper, we will review the current literature about the pharmacology and pharmacokinetics of intravenous levetiracetam and the safety profile of this new anticonvulsant in acute seizure management of both adults and children.

    Williams, Anne M; Davies, Anne; Griffiths, Gareth

    2009-06-01

    Nurses often use non-pharmacological measures to facilitate comfort for patients within the hospital setting. However, guidelines for use of these measures are commonly inadequate or absent. This paper presents 12 clinical practice guidelines that were developed from the findings of a literature review into non-pharmacological measures that are thought to facilitate patient comfort. The non-pharmacological measures addressed in these guidelines are: Aromotherapy, Distraction, Guided Imagery, Laughter, Massage, Music, Reiki, Heat or Cold, Meditation, Reflexology, Reposition and Transcutaneous Electrical Nerve Stimulation. These are preliminary guidelines for the use of non-pharmacological measures and further research and development of such guidelines is recommended. PMID:19531072

    Acetylsalicylic acid (aspirin) is a prototypic cyclooxygenase (COX) inhibitor. It was synthesized serendipitously from a natural compound, i.e., salicylic acid, with known analgesic activity. This chemical modification, obtained for the first time in an industrial environment in 1897, endowed aspirin with the unique capacity of acetylating and inactivating permanently COX-isozymes. Traditional nonsteroidal anti-inflammatory drugs (tNSAIDs) were developed to mimic the pharmacological effects of aspirin, using aspirin-sensitive experimental models of pain and inflammation as the template for screening new chemical entities. Among the tNSAIDs, some were endowed with moderate COX- selectivity (e.g., diclofenac), but no studies of sufficient size and duration were performed to show any clinically relevant difference between different members of the class. Similarly, no serious attempts were made to unravel the mechanisms involved in the shared therapeutic and toxic effects of tNSAIDs until the discovery of COX-2. This led to characterizing their main therapeutic effects as being COX-2-dependent and their gastrointestinal (GI) toxicity as being COX-1-dependent, and provided a rationale for developing a new class of selective COX-2 inhibitors, the coxibs. This review will discuss the clinical pharmacology of tNSAIDs and coxibs, and the clinical read-outs of COX-isozyme inhibition.

    Acanthopanax senticosus (Rupr. et Maxim) Harms (Araliaceae), also called Siberian Ginseng, Eleutherococcus senticosus, and Ciwujia in Chinese, is a widely used traditional Chinese herb that could invigorate qi, strengthen the spleen, and nourish kidney in the theory of Traditional Chinese Medicine. With high medicinal value, Acanthopanax senticosus (AS, thereafter) is popularly used as an "adaptogen" like Panax ginseng. In recent decades, a great number of chemical, pharmacological, and clinical studies on AS have been carried out worldwide. Several kinds of chemical compounds have been reported, including triterpenoid saponins, lignans, coumarins, and flavones, among which, phenolic compounds such as syringin and eleutheroside E, were considered to be the most active components. Considerable pharmacological experiments both in vitro and in vivo have persuasively demonstrated that AS possessed anti-stress, antiulcer, anti-irradiation, anticancer, anti-inflammatory and hepatoprotective activities, etc. The present review is an up-to-date and comprehensive analysis of the botany, chemistry, pharmacology, toxicity and clinical trials of AS.

    Full Text Available Amlodipine is the third generation calcium antagonist, 1,4-dihydropyridine derivative with the prolonged duration of the antihypertensive action, especially blocking L-type Ca2+ ion channels. It promotes beneficial therapeutic effect by coronary and other blood vessel diseases and thus delays development of the atherosclerosis. It has several known trade names, the most mentioned is Norvasc. Amlodipine is well tolerated in the clinics, it could be used in combinations with other drugs – diuretics, angiotensin-converting enzyme inhibitors, angiotensin II receptor antagonists, statins. Amlodipine at nanomolar concentrations binds to the voltage-dependent L-type calcium channels. It possesses optimal lipophylicity. Amlodipine also influences the NO-dependent metabolic processes, stimulates NO synthesis and prolongs NO action duration. Results of the studies of the amlodipine pharmacological and clinical properties are summarized in several reviews. The present review contains opinion from the scientific works of the last decades about the multisided or pleiotropic amlodipine mechanisms of action, it contains information about sometimes controversial clinical studies of the amlodipine vaso- and cardioprotective activity.

    Full Text Available Lonicerae japonicae flos, a widely used traditional Chinese medicine (TCM, has been used for several thousand years in China. Chinese Pharmacopeia once included Lonicerae japonicae flos of Caprifoliaceae family and plants of the same species named Lonicerae flos in general in the same group. Chinese Pharmacopeia (2005 Edition lists Lonicerae japonicae flos and Lonicerae flos under different categories, although they have the similar history of efficacy. In this study, we research ancient books of TCM, 4 main databases of Chinese academic journals, and MEDLINE/PubMed to verify the origins and effects of Lonicerae japonicae flos and Lonicerae flos in traditional medicine and systematically summarized the research data in light of modern pharmacology and toxicology. Our results show that Lonicerae japonicae flos and Lonicerae flos are similar pharmacologically, but they also differ significantly in certain aspects. A comprehensive systematic review and a standard comparative pharmacological study of Lonicerae japonicae flos and Lonicerae flos as well as other species of Lonicerae flos support their clinical safety and application. Our study provides evidence supporting separate listing of Lonicerae japonicae flos and Lonicerae flos in Chinese Pharmacopeia as well as references for revision of relevant pharmacopeial records dealing with traditional efficacy of Lonicerae japonicae flos and Lonicerae flos.

    Clinical pharmacology is a medical specialty whose practitioners teach, undertake research, frame policy, give information and advice about the actions and proper uses of medicines in humans and implement that knowledge in clinical practice. It involves a combination of several activities: drug discovery and development, training safe prescribers, providing objective and evidence-based therapeutic information to ethics, regulatory and pricing bodies, supporting patient care in an increasingly subspecialized arena where co-morbidities, polypharmacy, altered pharmacokinetics and drug interactions are common and developing and contributing to medicines policies for Governments. Clinical pharmacologists must advocate drug quality and they must also advocate for sustainability of the Discipline. However for this they need appropriate clinical service and training support. This Commentary discusses strategies to ensure the Discipline is supported by teaching, training and policy organizations, to communicate the full benefits of clinical pharmacology services, put a monetary value on clinical pharmacology services and to grow the clinical pharmacology workforce to support a growing clinical, academic and regulatory need.

    Pimpinella anisum (anise), belonging to Umbelliferae family, is an aromatic plant which has been used In Iranian traditional medicine (especially its fruits) as carminative, aromatic, disinfectant, and galactagogue. Because the wide traditional usage of Pimpinella anisum for treatment of diseases, in this review published scientific reports about the composition and pharmacological properties of this plant were collected with electronic literature search of GoogleScholar, PubMed, Sciencedirect, Scopus, and SID from 1970 to 2011. So far, different studies were performed on aniseeds and various properties such as antimicrobial, antifungal, antiviral, antioxidant, muscle relaxant, analgesic and anticonvulsant activity as well as different effects on gastrointestinal system have been reported of aniseeds. It can also reduce morphine dependence and has beneficial effects on dysmenorrhea and menopausal hot flashes in women. In diabetic patients, aniseeds showed hypoglycemic and hypolipidemic effect and reduce lipid peroxidation. The most important compounds of aniseeds essential oil were trans-anetole, estragole, γ-hymachalen, para-anisaldehyde and methyl cavicol. Due to broad spectrum of pharmacological effects, and very few clinical studies of Pimpinella anisum, more clinical trials are recommended to evaluate the beneficial effects of this plant in human models and synthesis of new drugs from the active ingredients of this plant in future.

    Full Text Available Maria Antonietta Catania1, Salvatore Cuzzocrea1,21Department of Clinical and Experimental Medicine and Pharmacology, School of Medicine, University of Messina; 2IRCCS Centro Neurolesi “Bonino-Pulejo”, Messina, ItalyAbstract: Cough constitutes an impressive expression of the normal defense mechanisms of the respiratory system. Productive cough associated with catarrh is an important protective system for the lung because it favors the upward movement of secretions and foreign bodies to the larynx and mouth. Cough may also appear without bronchial secretions, as dry cough, which may be persistent when inflammatory disease is chronic or when, in the early stages of respiratory disease, bronchial secretions are not yet fluid. Sometimes bronchitis-induced cough does not significantly affect quality of life, whilst in other cases cough may become so intense as to impair daily activities severely, resulting in permanent disability. This type of cough is one of the most frequent reasons for seeking medical advice. The use of cough suppressants may be appropriate for reaching a precise diagnosis and when dry cough is persistent. Cloperastine has been investigated in various types of cough and, unlike codeine, has been shown to possess dual activity. It also acts as a mild bronchorelaxant and has antihistaminic activity, without acting on the central nervous system or the respiratory center. Here we review the preclinical and clinical evidence of the efficacy and tolerability of cloperastine.Keywords: cough, cloperastine, inflammation, bronchitis

    1997-01-01

    Pain is the main reason prompting patients to consult their physicians. In acute conditions, pain has a very particular significance as a warning sign, enabling the physician to attempt a diagnosis. Nevertheless, its detrimental effect upon the individual (even in the case of acute pain) and its cost to society are now widely acknowledged. There can be no doubt about the physical component of pain, but the psychological and social aspects should not be ignored, particularly in the case of chronic pain. There is no single therapeutic approach to pain and, more often than not, successful treatment comprises a combination of several. Pharmacological treatments are undeniably the most common approach. In clinical practice, recent advances have been based upon an improved understanding of 'old' substances such as morphine and, at the same time, research continues in the hope of finding the 'ideal' analgesic-effective in most situations but without adverse effects: this appears to be a somewhat utopian arm at present, considering the number of different causes of pain. An improved understanding of the physiological mechanisms of pain has led, within the field of clinical practice, to several methods of differentiating pain. These depend on whether or not pain responds to morphine, or on the type of pain: pain due to an excess of nociception, pain resulting from deafferentation (caused by damage to nerve pathways) in the central or peripheral nervous system and psychogenic (idiopathic) pain. Likewise, there are several different ways of classifying analgesic treatments: according to the intensity of pain, as with use of the WHO ladder (which is based on the notion of steps) for the treatment of cancer pain; according to the presumed physiopathological mechanism and, in particular, the response to morphine, and according to the presumed central or peripheral mechanism of the drugs. In reality, peripherally acting drugs can also have a central mechanism of action, just as

  8. Optimizing the clinical pharmacology of tuberculosis medications.

    Egelund, E F; Alsultan, A; Peloquin, C A

    2015-10-01

    Tuberculosis (TB) treatment has changed little in the past 40 years. The current standard therapy requires four drugs for 2 months followed by two drugs for 4 months. This "short-course" regimen is not based on optimized pharmacokinetic and pharmacodynamic properties, but empiric evidence. A review of existing data suggests that pharmacokinetic variability with isoniazid and rifampin is greater than previously thought, and that efficacy is not as good as traditionally reported. Adding new drugs to the current regimen will be costly and time-consuming. Maximizing the efficacy of the current medications is a less expensive and more feasible option. This article reviews the current potential of the first-line TB drugs (rifamycins, isoniazid, pyrazinamide, and ethambutol) as well as the fluoroquinolones to introduce a true short-course TB regimen.

    Full Text Available Abstract Background Fragile X syndrome (FXS is considered the most common cause of inherited mental retardation. Affected people have mental impairment that can include Attention Deficit and/or Hyperactivity Disorder (ADHD, autism disorder, and speech and behavioural disorders. Several pharmacological interventions have been proposed to treat those impairments. Methods Systematic review of the literature and summary of the evidence from clinical controlled trials that compared at least one pharmacological treatment with placebo or other treatment in individuals with diagnosis of FXS syndrome and assessed the efficacy and/or safety of the treatments. Studies were identified by a search of PubMed, EMBASE and the Cochrane Databases using the terms fragile X and treatment. Risk of bias of the studies was assessed by using the Cochrane Collaboration criteria. Results The search identified 276 potential articles and 14 studies satisfied inclusion criteria. Of these, 10 studies on folic acid (9 with crossover design, only 1 of them with good methodological quality and low risk of bias did not find in general significant improvements. A small sample size trial assessed dextroamphetamine and methylphenidate in patients with an additional diagnosis of ADHD and found some improvements in those taking methylphenidate, but the length of follow-up was too short. Two studies on L-acetylcarnitine, showed positive effects and no side effects in patients with an additional diagnosis of ADHD. Finally, one study on patients with an additional diagnosis of autism assessed ampakine compound CX516 and found no significant differences between treatment and placebo. Regarding safety, none of the studies that assessed that area found relevant side effects, but the number of patients included was too small to detect side effects with low incidence. Conclusion Currently there is no robust evidence to support recommendations on pharmacological treatments in patients with

    Yugoslavia has a modern drug legislature and a selective drug market. With about 910 substances and 1250 brand names the number of drugs is among the lowest among the European countries. Most products on the market satisfy high criteria of safety to efficacy ratio. Still, the regional health insurance authorities of the Federal republics of Serbia and of Croatia limited the number of drugs to be reimbursed by the insurance scheme. The reason for this move and its justification is given by--the inertia of the complicated procedure of withdrawal from the market of a drug which is obsolete or considered today not possess the ascribed efficacy, existence of unjustly high expectations regarding the efficacy of certain drugs by both the medical profession and the layman and which lead to overprescribing (i.e. vitamin combinations, laxatives and drugs, cerebrovascular insufficiency), and--the responsibility of the public health administration for setting priorities in spending of the available funds. The allocation of funds available for medicinal drugs have been without any kind of regulation and control until now. The introduction of limitations in the reimbursement of price for certain drugs is the first measure initiated to stimulate the optimal use of drugs. As the optimal drug use is considered the therapy with the most favorable safety/efficacy and cost/efficiency ratios. The other measures available and which ought to be initiated are those based on the drug utilization studies. The prescriptions are already computerized im most settings, so the feedback of information ot the prescribing physicians could be possible after adequate analysis of the data. The team of clinical pharmacologist already active in drug utilization studies is available and ready to meet the challenge of improving therapeutic practices. PMID:2642196

    To improve the transition from research to development a critical evaluation of the individual project by research and disease area teams is required to include input from pharmacology, toxicology, pharmacokinetics, galenics, clinical pharmacology, clinical as well as regulatory experts and marketing. Decisions on the individual development strategy should be made prior to the start of development and all projects should be reviewed at predefined stages throughout the product development life cycle. This ensures consistency of decision-making not only during the development of individual products but throughout the entire development pipeline. Studies in the exploratory stage of drug development should be designed for decision making in contrast to later clinical trials in the confirmatory stage that require power for proof-of-safety and proof-of-efficacy. The more thorough and profound studies have been carried out during this exploratory stage of drug development, the earlier a decision can be made on the continuation or discontinuation of further development, thus saving development time and money and assessing and considerably reducing the risk for the patients and increasing the success rate of the project in the later confirmatory effectiveness trial with an adequate number of subjects receiving the new therapy under typical conditions of use. Strategies which may be helpful to improve the quality of decisions in drug discovery and drug development are: discovery experiments should be done to critically evaluate the compound, the "killer" experiments should be done as early as possible, continuous effort on preclinical disease models is necessary to improve predictability of efficacy in patients ("humanized" research): genomic technology should be used to identify novel, disease-related targets and to characterise preclinical test systems, improvement of knowledge and experience concerning the relevance of new technologies for the clinical picture; genotyping

    these clinical patterns, such as multidimensionally impaired disorder and multiple complex developmental disorder. In the context of a multimodal approach, including behavioral, social, scholastic and familial interventions, a pharmacological treatment is usually the core treatment. Available experience from the few controlled studies, open studies and case reports on pharmacotherapy in children with schizophrenia aged <12 years is critically analysed in this review, with particular reference to the use of atypical antipsychotics in clinical practice. To date, the major evidence supports the efficacy of risperidone and olanzapine, while clozapine seems an effective option in treatment-refractory cases. Published experience with newer atypical antipsychotics (quetiapine, ziprasidone, aripiprazole) is still lacking in this age range. Safety data (namely extrapyramidal symptoms, weight gain, hyperprolactinaemia, haematological adverse effects, seizures, hepatotoxicity, metabolic effects, neuroleptic malignant syndrome and cardiovascular effects) are reviewed and discussed, along with strategies for management.

    Bryophyllum pinnatum (syn. Kalanchoe pinnata) is a succulent perennial plant native to Madagascar that was introduced in anthroposophic medicine in the early 20th century. In recent years, we conducted a large collaborative project to provide reliable data on the chemical composition, pharmacological properties, and clinical efficacy of Bryophyllum. Here, we comprehensively review the phytochemistry, as well as the pharmacological and clinical data. As to the pharmacology, special emphasis is given to properties related to the use in anthroposophic medicine as a treatment for "hyperactivity diseases", such as preterm labor, restlessness, and sleep disorders. Studies suggesting that B. pinnatum may become a new treatment option for overactive bladder syndrome are also reviewed. Tolerability is addressed, and toxicological data are discussed in conjunction with the presence of potentially toxic bufadienolides in Bryophyllum species. The few data available on two related species with medicinal uses, Bryophyllum daigremontianum and Bryophyllum delagoense, have also been included. Taken together, current data support the use of B. pinnatum for the mentioned indications, but further studies are needed to fully understand the modes of action, and to identify the pharmacologically active constituents.

    2013-10-01

    Full Text Available There is a good amount of evidence that exposure therapy is an effective treatment for posttraumatic stress disorder (PTSD. Notwithstanding its efficacy, there is room for improvement, since a large proportion of patients does not benefit from treatment. Recently, an interesting new direction in the improvement of exposure therapy efficacy for PTSD emerged. Basic research found evidence of the pharmacological enhancement of the underlying learning and memory processes of exposure therapy. The current review aims to give an overview of clinical studies on pharmacological enhancement of exposure-based treatment for PTSD. The working mechanisms, efficacy studies in PTSD patients, and clinical utility of four different pharmacological enhancers will be discussed: D-cycloserine, MDMA, hydrocortisone, and propranolol.

    May, Marcus; Schindler, Christoph

    2016-04-01

    Patients with type 2 diabetes mellitus often require multifactorial pharmacological treatment due to different comorbidities. An increasing number of concomitantly taken medications elevate the risk of the patient experiencing adverse drug effects or drug interactions. Drug interactions can be divided into pharmacokinetic and pharmacodynamic interactions affecting cytochrome (CYP) enzymes, absorption properties, transporter activities and receptor affinities. Furthermore, nutrition, herbal supplements, patient's age and gender are of clinical importance. Relevant drug interactions are predominantly related to sulfonylureas, thiazolidinediones and glinides. Although metformin has a very low interaction potential, caution is advised when drugs that impair renal function are used concomitantly. With the exception of saxagliptin, dipeptidyl peptidase-4 (DPP-4) inhibitors also show a low interaction potential, but all drugs affecting the drug transporter P-glycoprotein should be used with caution. Incretin mimetics and sodium-glucose cotransporter-2 (SGLT-2) inhibitors comprise a very low interaction potential and are therefore recommended as an ideal combination partner from the clinical-pharmacologic point of view.

    Registration of innovative biologics in Emerging Markets (EMs) poses many opportunities and challenges. The BRIC-MT countries (Brazil, Russia, India, China, Mexico, and Turkey) that are the fastest growing markets and regulators in these countries have imposed certain requirements, including the need for local clinical studies, for registration of biologics. The regulatory landscape in these countries is rapidly evolving, which necessitates an up-to-date understanding of such requirements. There is growing evidence which suggests that race, after accounting for body weight differences, may not influence the pharmacokinetics of biologics to the same extent that it does for small molecules. Thus, the requirements for clinical pharmacology trials in EMs are driven mainly by regulatory needs set forth by local Ministry of Health. In addition to the clinical Phase I to III studies done in the global program that supports registration in large geographies, countries such as China require local single and multiple dose Phase I studies. Participating in global studies with clinical sites within their country may be sufficient for some markets, while other regulators may be satisfied with a Certificate of Pharmaceutical Product. This paper discusses the current requirements for registration of innovative biologics in key EMs. PMID:25707959

    BACKGROUND Obsessive-compulsive disorder (OCD) is a relatively common and disabling condition. OBJECTIVES To determine the clinical effectiveness, acceptability and cost-effectiveness of pharmacological and psychological interventions for the treatment of OCD in children, adolescents and adults. DATA SOURCES We searched the Cochrane Collaboration Depression, Anxiety and Neurosis Trials Registers, which includes trials from routine searches of all the major databases. Searches were conducted from inception to 31 December 2014. REVIEW METHODS We undertook a systematic review and network meta-analysis (NMA) of the clinical effectiveness and acceptability of available treatments. Outcomes for effectiveness included mean differences in the total scores of the Yale-Brown Obsessive-Compulsive Scale or its children's version and total dropouts for acceptability. For the cost-effectiveness analysis, we developed a probabilistic model informed by the results of the NMA. All analyses were performed using OpenBUGS version 3.2.3 (members of OpenBUGS Project Management Group; see www.openbugs.net ). RESULTS We included 86 randomised controlled trials (RCTs) in our systematic review. In the NMA we included 71 RCTs (54 in adults and 17 in children and adolescents) for effectiveness and 71 for acceptability (53 in adults and 18 in children and adolescents), comprising 7643 and 7942 randomised patients available for analysis, respectively. In general, the studies were of medium quality. The results of the NMA showed that in adults all selective serotonin reuptake inhibitors (SSRIs) and clomipramine had greater effects than drug placebo. There were no differences between SSRIs, and a trend for clomipramine to be more effective did not reach statistical significance. All active psychological therapies had greater effects than drug placebo. Behavioural therapy (BT) and cognitive therapy (CT) had greater effects than psychological placebo, but cognitive-behavioural therapy (CBT) did not

    Flavonoids and polyphenols are heterocyclic molecules that have been associated with beneficial effects on human health, such as reducing the risk of various diseases like cancer, diabetes, and cardiovascular and brain diseases. Protocatechuic acid (PCA) is a type of widely distributed naturally occurring phenolic acid. PCA has structural similarity with gallic acid, caffeic acid, vanillic acid, and syringic acid which are well-known antioxidant compounds. More than 500 plants contain PCA as active constituents imparting various pharmacological activity and these effects are due to their antioxidant activities, along with other possible mechanisms, such as anti-inflammatory properties and interaction with several enzymes. Over the past two decades, there have been an increasing number of publications on polyphenols and flavonoids, which demonstrate the importance of understanding the chemistry behind the antioxidant activities of both natural and synthesized compounds, considering the benefits from their dietary ingestion as well as pharmacological use. This work aims to review the pharmacological effects of PCA molecules in humans and the structural aspects that contribute to these effects. PMID:25006494

    Acute heart failure remains a major cause of morbidity, and its treatment requires an increasing investment of the health care system. Whereas success in treating chronic heart failure has been achieved over the last decades, several pharmacological approaches for acute heart failure have been introduced but have failed to demonstrate any clinical benefit. Serelaxin is a recombinant human relaxin-2 vasoactive peptide that causes systemic and renal vasodilation. Data suggest that the clinical benefits may be attributable to a potential combination of multiple actions of serelaxin, including improving systemic, cardiac, and renal hemodynamics, and protecting cells and organs from damage via neurohormonal, anti-inflammatory, antiremodeling, antifibrotic, anti-ischemic, and proangiogenic effects. Recently, a number of clinical trials have demonstrated that serelaxin infusion over 48 hours improved dyspnea with more rapid relief of congestion during the first days after admission for heart failure. In addition, administration of serelaxin diminished cardiac, renal, and hepatic damage, which were associated with improved long-term mortality. Available data support substantial clinical benefits and significant promise for serelaxin as a treatment option for patients with acute heart failure. This review focuses on the pharmacology and mechanisms of action of serelaxin and provides a detailed discussion of the clinical evidence for this novel therapy in acute heart failure. PMID:26331289

    Dextromethorphan (DM) has been used for more than 50years as an over-the-counter antitussive. Studies have revealed a complex pharmacology of DM with mechanisms beyond blockade of N-methyl-d-aspartate (NMDA) receptors and inhibition of glutamate excitotoxicity, likely contributing to its pharmacological activity and clinical potential. DM is rapidly metabolized to dextrorphan, which has hampered the exploration of DM therapy separate from its metabolites. Coadministration of DM with a low dose of quinidine inhibits DM metabolism, yields greater bioavailability and enables more specific testing of the therapeutic properties of DM apart from its metabolites. The development of the drug combination DM hydrobromide and quinidine sulfate (DM/Q), with subsequent approval by the US Food and Drug Administration for pseudobulbar affect, led to renewed interest in understanding DM pharmacology. This review summarizes the interactions of DM with brain receptors and transporters and also considers its metabolic and pharmacokinetic properties. To assess the potential clinical relevance of these interactions, we provide an analysis comparing DM activity from in vitro functional assays with the estimated free drug DM concentrations in the brain following oral DM/Q administration. The findings suggest that DM/Q likely inhibits serotonin and norepinephrine reuptake and also blocks NMDA receptors with rapid kinetics. Use of DM/Q may also antagonize nicotinic acetylcholine receptors, particularly those composed of α3β4 subunits, and cause agonist activity at sigma-1 receptors. PMID:27139517

    Abstract Background In palliative care patients, fatigue can be severely debilitating and is often not counteracted with rest, thereby impacting daily activity and quality of life. Further complicating issues are the multidimensionality, subjective nature and lack of a consensus definition of fatigue. The review aimed to evaluate the efficacy of pharmacological treatments for fatigue in palliative care, with a focus on patients at an advanced stage of disease, including patients with cancer and other chronic diseases. Methods We considered randomized controlled trials concerning adult palliative care with a focus on pharmacological treatment of fatigue compared with placebo, application of two drugs, usual care or a non‐pharmacological intervention. The primary outcome had to be non‐specific fatigue (or related terms such as asthenia). We searched the CENTRAL, MEDLINE, PsycINFO and EMBASE, and a selection of cancer journals up to 28 April 2014. Two review authors independently assessed trial quality and extracted the data. Results We screened 1645 publications of which 45 met the inclusion criteria. In total, we analysed data from 18 drugs and 4696 participants. There was a very high degree of statistical and clinical heterogeneity in the trials. Meta‐analysis of data was possible for modafinil, pemoline, and methylphenidate. Conclusions Due to the limited evidence, we cannot recommend a specific drug for the treatment of fatigue in palliative care patients. Some drugs, which may be beneficial for the treatment of fatigue associated with palliative care such as amantadine, methylphenidate, and modafinil, should be further researched. PMID:27066315

    Diarrhea represents a major health problem for travelers to developing countries. Although the syndrome is usually self-limited and recovery occurs in the majority of cases without any specific form of therapy, there is a need for safe and effective ways of preventing and treating it. Since the syndrome is most often caused by an infection acquired by ingesting fecally contaminated food or beverages, precautions regarding dietary habits remain the cornerstone of prophylaxis, but dietary self-restrictions do not always translate to reduced rates of diarrheal illness. Administration of probiotics (e.g. lactobacilli or Saccharomyces boulardii) and immunoprophylaxis with the newer oral cholera vaccines have been tried with promising results. Antimicrobials remain, however, the most successful form of prophylaxis, being effective in up to 90% of travelers. For those with impaired health who will take prophylaxis, systemic agents with proved efficacy should be recommended. For other otherwise healthy persons, poorly absorbed agents are preferable in order to avoid the serious, albeit rare, toxicity of systemic drugs. The key factor in the management of acute watery traveler's diarrhea, particularly in infants and young children, is the restoration of water and electrolyte balance. This does not reduce the duration of the illness but will limit dehydration and prevent acidosis. Many patients will require no additional therapy, whereas some will need pharmacologic treatment to shorten the duration of diarrhea or to relieve the accompanying symptoms, like abdominal discomfort, nausea and vomiting. A typical 3- to 5-day illness can be reduced to approximately 1 day by trimethoprim-sulfamethoxazole (TMP-SMX) combination. Some other systemic antimicrobials have been successfully used but, during the last few years, the 4-fluoroquinolone drugs have received considerable attention and have been shown to be highly effective in reducing the duration of traveler's diarrhea.

    Tinospora crispa (L.) Hook. f. & Thomson (Menispermaceae), found in the rainforests or mixed deciduous forests in Asia and Africa, is used in traditional medicines to treat numerous health conditions. This review summarizes the up-to-date reports about the ethnobotany, phytochemistry, pharmacological activities, toxicology, and clinical trials of the plant. It also provides critical assessment about the present knowledge of the plant which could contribute toward improving its prospect as a source of lead molecules for drug discovery. The plant has been used traditionally in the treatment of jaundice, rheumatism, urinary disorders, fever, malaria, diabetes, internal inflammation, fracture, scabies, hypertension, reducing thirst, increasing appetite, cooling down the body temperature, and maintaining good health. Phytochemical analyses of T. crispa revealed the presence of alkaloids, flavonoids, and flavone glycosides, triterpenes, diterpenes and diterpene glycosides, cis clerodane-type furanoditerpenoids, lactones, sterols, lignans, and nucleosides. Studies showed that the crude extracts and isolated compounds of T. crispa possessed a broad range of pharmacological activities such as anti-inflammatory, antioxidant, immunomodulatory, cytotoxic, antimalarial, cardioprotective, and anti-diabetic activities. Most pharmacological studies were based on crude extracts of the plant and the bioactive compounds responsible for the bioactivities have not been well identified. Further investigations are required to transform the experience-based claims on the use of T. crispa in traditional medicine practices into evidence-based information. The plant extract used in pharmacological and biological studies should be qualitatively and quantitatively analyzed based on its biomarkers. There should be detail in vitro and in vivo studies on the mechanisms of action of the pure bioactive compounds and more elaborate toxicity study to ensure safety of the plant for human use. More

    Since Helicobacter pylori was discovered in 1980, it has been considered as a major cause in the pathogenesis of gastric ulcer, mucosa-associated lymphoid tissue (MALT) lymphomas, and gastric cancer. Eventually antibiotics were designed to eradicate this bacterium, which not only prevent peptic ulcer recurrence but also decrease the chances of developing gastric cancer. Propitious consequences of these antibiotic regimens and better hygienic conditions, particularly in developed countries, resulted in significant decline in the prevalence of H. pylori infection. However, persistent high H. pylori infection in developing countries, decreased patience compliance and emerging antibiotic resistance forced researchers to quest for novel candidates. Herbal medicines have always served as a leading source in drug discovery. Since time immemorial, herbs have been used to treat various disorders covering from minor illnesses as pain to life threatening conditions like cancer. Ample amount of studies from different parts of the world have shown promising activities of medicinal herbs not only against H. pylori but also associated disorders while employing in vitro, in vivo and clinical studies. In this review, these multiple pharmacological effects of medicinal plants and their chemical constituents will be discussed in relation to H. pylori not only to scientifically evaluate the beneficial effects of these medicinal plants but to also critically analyze their plausible role as chemo preventive agents against H. pylori-associated disorders.

    Many aspects of long-term pharmacological treatments for anxiety disorders (AnxDs) are still debated. We undertook an updated systematic review of long-term pharmacological studies on panic disorder (PD), generalized anxiety disorder (GAD), and social anxiety disorder (SAD). Relevant studies dating from January 1, 2012 to August 31, 2015 were identified using the PubMed database and a review of bibliographies. Of 372 records identified in the search, five studies on PD and 15 on GAD were included in the review. No studies on SAD were found. Our review confirms the usefulness of long-term pharmacological treatments for PD and GAD and suggests that they can provide further improvement over that obtained during short-term therapy. Paroxetine, escitalopram, and clonazepam can be effective for long-term treatment of PD. However, further studies are needed to draw conclusions about the long-term benzodiazepine use in PD, particularly for the possible cognitive side-effects over time. Pregabalin and quetiapine can be effective for long-term treatment of GAD, while preliminary suggestions emerged for agomelatine and vortioxetine. We did not find any evidence for determining the optimal length and/or dosage of medications to minimize the relapse risk. Few investigations have attempted to identify potential predictors of long-term treatment response. Personalized treatments for AnxDs can be implemented using predictive tools to explore those factors affecting treatment response/tolerability heterogeneity, including neurobiological functions/clinical profiles, comorbidity, biomarkers, and genetic features, and to tailor medications according to each patient's unique features.

    Skin picking disorder (SPD) is a newly recognized psychiatric disorder in Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. A systematic review was conducted to assess the efficacy of pharmacological and behavioral interventions for SPD. Electronic databases were searched for randomized controlled trials (RCTs) or uncontrolled trials involving at least 10 subjects that examined the efficacy of pharmacological and behavioral interventions for SPD. We examined the improvement associated with interventions compared with inactive control conditions in RCTs and improvement over time in uncontrolled trials and within the treatment arms of RCTs. We stratified studies on the basis of intervention type. Meta-analysis included 11 studies. All interventions (including inactive control conditions) demonstrated significant improvement over the course of short-term clinical trials in SPD. Only behavioral treatments demonstrated significant benefits compared with inactive control conditions. There was no evidence from RCTs that pharmacotherapy with selective serotonin reuptake inhibitors or lamotrigine were more effective at treating SPD than placebo. Our meta-analysis suggests that subjects with SPD show significant improvement during short-term trials, regardless of the efficacy of the underlying intervention. This finding suggests that uncontrolled trials are of particularly limited utility for assessing efficacy of treatments in SPD. Future research should concentrate on developing larger placebo-controlled RCTs to examine efficacy of novel pharmacological agents. In addition, research should focus on improving accessibility of behavioral treatments with demonstrated efficacy for SPD. PMID:26872117

    Therapies that modulate cyclic guanosine-3'-5'-monophosphate (cGMP) have emerged as one of the most successful areas in recent drug discovery and clinical pharmacology. Historically, their focus has been on cardiovascular disease phenotypes; however, cGMP's relevance is likely to go beyond this rather limited organ-based set of indications. Moreover, the multitude of targets and their apparent interchangeability is a proof-of-concept of network pharmacology. PMID:26765222

    Off-target pharmacology may contribute to both adverse and beneficial effects of a new drug. In vitro pharmacological profiling is often applied early in drug discovery; there are fewer reports addressing the relevance of broad profiles to clinical adverse effects. Here, we have characterized the pharmacological profile of the active metabolite of fostamatinib, R406, linking an understanding of drug selectivity to the increase in blood pressure observed in clinical studies. R406 was profiled in a broad range of in vitro assays to generate a comprehensive pharmacological profile and key targets were further investigated using functional and cellular assay systems. A combination of traditional literature searches and text-mining approaches established potential mechanistic links between the profile of R406 and clinical side effects. R406 was selective outside the kinase domain, with only antagonist activity at the adenosine A3 receptor in the range relevant to clinical effects. R406 was less selective in the kinase domain, having activity at many protein kinases at therapeutically relevant concentrations when tested in multiple in vitro systems. Systematic literature analyses identified KDR as the probable target underlying the blood pressure increase observed in patients. While the in vitro pharmacological profile of R406 suggests a lack of selectivity among kinases, a combination of classical searching and text-mining approaches rationalized the complex profile establishing linkage between off-target pharmacology and clinically observed effects. These results demonstrate the utility of in vitro pharmacological profiling for a compound in late-stage clinical development. PMID:26516587

    Platycladus orientalis leaves (Cebaiye) have been used for thousands of years as traditional Chinese medicine (TCM). According to the theory of TCM, they are categorized as a blood-cooling and hematostatic herb. In clinical practice, they were usually prescribed with heat-clearing herbs to reinforce the efficacy of hemostasis. The review provides the up-to-date information from 1980 to present that is available on the botany, processing research, phytochemistry, pharmacology and toxicology of the leaves. The information is collected from scientific journals, books, theses and reports via library and electronic search (Google Scholar, Pubmed and CNKI). Through literature reports, we can find that the leaves show a wide spectrum of pharmacological activities, such as anti-inflammatory, antioxidant, antimicrobial, disinsection, anticancer, diuretic, hair growth-promoting, neuroprotective and antifibrotic activities. Diterpene and flavonoids would be active constituents in P. orientalis leaves. Many studies have provided evidence for various traditional uses. However, there is a great need for additional studies to elucidate the mechanism of blood-cooling and hematostatic activity of the leaves. Therefore, the present review on the botany, traditional uses, phytochemistry and toxicity has provided preliminary information for further studies of this herb. PMID:24871649

    Full Text Available Elizabeth Ralevski, Lening A Olivera-Figueroa, Ismene Petrakis Yale University School of Medicine, Department of Psychiatry, VA Connecticut Healthcare System, West Haven, CT, USA Background: Although posttraumatic stress disorder (PTSD and alcohol use disorders (AUD frequently co-occur there are no specific treatments for individuals diagnosed with these comorbid conditions. The main objectives of this paper are to review the literature on pharmacological options for PTSD and comorbid AUD, and to summarize promising behavioral and alternative interventions for those with these dual diagnoses. Methods: We conducted a comprehensive search on PsycINFO and MEDLINE/PubMed databases using Medical Subject Headings terms in various combinations to identify articles that used pharmacotherapy for individuals with dual diagnoses of PTSD and AUD. Similar strategies were used to identify articles on behavioral and alternative treatments for AUD and PTSD. We identified and reviewed six studies that tested pharmacological treatments for patients with PTSD and comorbid AUD. Results: The literature on treatment with US Food and Drug Administration approved medications for patients with dual diagnosis of PTSD and AUD is very limited and inconclusive. Promising evidence indicates that topiramate and prazosin may be effective in reducing PTSD and AUD symptoms in individuals with comorbidity. Seeking safety has had mixed efficacy in clinical trials. The efficacy of other behavioral and alternative treatments (mindfulness-based, yoga, and acupuncture is more difficult to evaluate since the evidence comes from small, single studies without comparison groups. Conclusion: There is a clear need for more systematic and rigorous study of pharmacological, behavioral, and alternative treatments for patients with dual diagnoses of PTSD and AUD.

    Rehmannia glutinosa, a widely used traditional Chinese herb, belongs to the family of Scrophulariaceae, and is taken to nourish Yin and invigorate the kidney in traditional Chinese medicine (TCM) and has a very high medicinal value. In recent decades, a great number of chemical and pharmacological studies have been done on Rehmannia glutinosa. More than 70 compounds including iridoids, saccharides, amino acid, inorganic ions, as well as other trace elements have been found in the herb. Studies show that Rehmannia glutinosa and its active principles possess wide pharmacological actions on the blood system, immune system, endocrine system, cardiovascular system and the nervous system. Currently, the effective monomeric compounds or active parts have been screened for the pharmacological activity of Rehmannia glutinosa and the highest quality scientific data is delivered to support the further application and exploitation for new drug development.

    To evaluate the statistical and clinical efficacy of the pharmacological treatments of nocturia using non-antidiuretic agents. A literature review of treatments of nocturia specifically addressing the impact of alpha blockers, 5-alpha reductase inhibitors (5ARI) and antimuscarinics on reduction in nocturnal voids. Despite commonly reported statistically significant results, nocturia has shown a poor clinical response to traditional therapies for benign prostatic hyperplasia including alpha blockers and 5ARI. Similarly, nocturia has shown a poor clinical response to traditional therapies for overactive bladder including antimuscarinics. Statistical success has been achieved in some groups with a variety of alpha blockers and antimuscarinic agents, but the clinical significance of these changes is doubtful. It is likely that other types of therapy will need to be employed in order to achieve a clinically significant reduction in nocturia. PMID:21518417

Findings from 19 large open studies and controlled clinical trials show that the use of atomoxetine or extended-release methylphenidate formulations, together with psychological therapy, yield promising though inconclusive results about short term efficacy of these drugs in the treatment of adult ADHD in patients with SUD and no other severe mental disorders. However, the efficacy of these drugs is scant or lacking for treating concurrent SUD. No serious safety issues have been associated with these drugs in patients with co-morbid SUD-ADHD, given their low risk of abuse and favourable side effect and drug-drug interaction profile. The decision to treat adult ADHD in the context of active SUD depends on various factors, some directly related to SUD-ADHD co-morbidity (e.g. degree of diagnostic uncertainty for ADHD) and other factors related to the clinical expertise of the medical staff and availability of adequate resources (e.g. the means to monitor compliance with pharmacological treatment). Our recommendation is that clinical decisions be individualized and based on a careful analysis of the advantages and disadvantages of pharmacological treatment for ADHD on a case-by-case basis in the context of active SUD.

    An integrated approach of neonatal analgesia starts with the systematic evaluation of pain and should be followed by effective interventions, mainly based on the appropriate (i.e. safe and effective) administration of analgesics. In contrast to the more potent opioids, data on the pharmacokinetics and -dynamics of non-opioid analgesics in this specific population are still rare or even lacking. We therefore evaluated various aspects of developmental pharmacology of non-opioid analgesics (paracetamol, ibuprofen, acetylsalicyl acid) in neonates. We first performed a single dose propacetamol study in preterm and term neonates. Based on these preliminary findings, a repeated dose administration scheme was developed and tested and maturational aspects from preterm till teenage were documented. Although non-selective COX-inhibitors might be effective in the treatment of postoperative or inflammatory pain syndromes in neonates, potential efficacy should be balanced against the drugs' safety profile. Neonatal renal clearance strongly depends on glomerular filtration rate (GFR) and GFR itself strongly depends on the vaso-dilatative of prostaglandins on the afferent arterioli. We therefore evaluated the impact of the administration of ibuprofen or acetylsalicylic acid on renal clearance in preterm infants and hereby used amikacin clearance as a surrogate marker. We hereby documented the negative effect of ibuprofen on glomerular filtration rate in preterm infants up to 34 weeks and we were able to show that ibuprofen and acetylsalicylic acid had an equal impact on the glomerular filtration rate.

    Three species of the genus Trollius (Ranunculaceae) are traditionally used to treat upper respiratory tract infections, pharyngitis, tonsillitis, bronchitis, cold with fever, acute tympanitis, aphthae, mouth sore, hemorrhage and pain of gums, acute lymphangitis and acute periostitis. However, only a few studies support its traditional use. These are studies of the biological activity of extracts and/or compounds of selected species of Trollius, but there are no clinical studies proving the effectiveness or possible toxic effects. Until now, the following activity of extracts and/or compounds from certain species of Trollius used in traditional medicine has been proven: antiviral, antibacterial, antiinflammatory and antioxidant. The review showed that flavonoids, mainly C-glycosides, were characteristic of the species Trollius. Furthermore, other main groups of compounds are carotenoids, organic acids, terpenes, alkaloids, sterols, lactones and carbohydrates. The essential oil mainly contains compounds from the group of benzenoids, nitrogen-containing compounds, monoterpenoids and sesquiterpenoids, irregular terpenes and macrocyclic epoxide.

    Full Text Available Arthur E Frankel Department of Internal Medicine, Simmons Comprehensive Cancer Center, The University of Texas Southwestern Medical Center, Dallas, TX, USA Until recent decades, the role of the immune system in harnessing tumor growth was based on anecdotal observations of increased cancers in immune-compromised patients, the benefits of graft-versus-leukemia in allogeneic stem cell transplants, and the limited but reproducible anticancer activity of several lymphokines, including interferon and interleukin (IL-2. Vaccine studies and infusions of "activated" lymphocytes yielded variable clinical responses and disease control. An improved understanding of the molecular and cell mechanisms of the innate and adaptive immune system in cancer-bearing animals and the discovery of an immune-suppressive tumor microenvironment then led to development and testing of a battery of new drug and cell-based approaches to trigger antitumor immunity. This issue of Clinical Pharmacology: Advances and Applications highlights some of the new protein-based compounds that are radically changing the cancer therapeutic landscape. The purpose of this collection of reviews is to inform the readership regarding the importance of the seismic change in cancer therapeutics and stimulate efforts to find novel niches and combinations of agents similar to recent advances in the application of cancer pathway inhibitors.

    Faymonville, M E; Libbrecht, D

    2008-11-01

    Our understanding of the pathophysiologic mechanisms of chronic pain progresses; the complexity of the problem justifies our need for new molecules and new ways of administration that will help to further optimise and better individualize our pharmacologic therapies. Whereas acute pain can be considered an alarm signal, chronic pain constitutes, per se, a syndrome that requires a meticulous selection of the analgesic drug(s). Since pain is permanent, the continuous administration of the analgesic is recommended rather than an on demand administration. Transdermic modes of administration are of value for the treatment of chronic pain because they allow a progressive delivery of the active compound together with the maintenance of stable plasma levels of the drug. Buprenorphine is a semi-synthetic opioid that is available in the sublingual, injectable, or transdermic forms. The matrix patch of buprenorphine represents a major asset for the treatment of chronic pain, whether it be cancerous in origin, or not. Its efficacy and safety have been clearly demonstrated in randomised double blind trials as well as in post-marketing surveillance observations. Buprenorphine, administered as a transdermal therapeutic system, induces a dose-related pain relief, whatever the nature of the pain and the age of the patient. Buprenorphine also exerts an analgesic action on neuropathic pain. It differs from other opioids by its affinity as a partial agonist on mu and kappa receptors, and as a complete agonist of ORL-1 receptors. Therefore, transdermal buprenorphine will be useful to all physicians having to control severe pain by powerful opioids. PMID:19112993

    2016-01-01

    Traumatic brain injury (TBI) is the most common cause of long-term disability in the United States. A significant proportion of children who experience a TBI will have moderate or severe injuries, which includes a period of decreased responsiveness. Both pharmacological and non-pharmacological modalities are used for treating disorders of consciousness after TBI in children. However, the evidence supporting the use of potential therapies is relatively scant, even in adults, and overall, there is a paucity of study in pediatrics. The goal of this review is to describe the state of the science for use of pharmacologic and non-pharmacologic interventions for disorders of consciousness in the pediatric population.

    Full Text Available Abstract Background Retrospective research requires longitudinal data, and repositories derived from electronic health records (EHR can be sources of such data. With Health Information Technology for Economic and Clinical Health (HITECH Act meaningful use provisions, many institutions are expected to adopt EHRs, but may be left with large amounts of financial and historical clinical data, which can differ significantly from data obtained from newer systems, due to lack or inconsistent use of controlled medical terminologies (CMT in older systems. We examined different approaches for semantic enrichment of financial data with CMT, and integration of clinical data from disparate historical and current sources for research. Methods Snapshots of financial data from 1999, 2004 and 2009 were mapped automatically to the current inpatient pharmacy catalog, and enriched with RxNorm. Administrative metadata from financial and dispensing systems, RxNorm and two commercial pharmacy vocabularies were used to integrate data from current and historical inpatient pharmacy modules, and the outpatient EHR. Data integration approaches were compared using percentages of automated matches, and effects on cohort size of a retrospective study. Results During 1999-2009, 71.52%-90.08% of items in use from the financial catalog were enriched using RxNorm; 64.95%-70.37% of items in use from the historical inpatient system were integrated using RxNorm, 85.96%-91.67% using a commercial vocabulary, 87.19%-94.23% using financial metadata, and 77.20%-94.68% using dispensing metadata. During 1999-2009, 48.01%-30.72% of items in use from the outpatient catalog were integrated using RxNorm, and 79.27%-48.60% using a commercial vocabulary. In a cohort of 16304 inpatients obtained from clinical systems, 4172 (25.58% were found exclusively through integration of historical clinical data, while 15978 (98% could be identified using semantically enriched financial data.

    2011-12-01

    Full Text Available Abstract Dabigatran is an emerging oral anticoagulant which is a direct inhibitor of thrombin activity. It has been approved in the European Union and the United States of America for the prevention of thrombosis after major orthopedic surgery. It has also been approved by the American Food and Drug Administration and the European Medicines Agency for the prevention of stroke in chronic atrial fibrillation. Dabigatran provides a stable anticoagulation effect without any need to perform periodical laboratory controls. Of note, there is a growing amount of clinical evidence which shows its safety and efficacy. For these reasons, dabigatran may suppose a revolution in oral anticoagulation. However, two important limitations remain. First, it is contraindicated in patients with end-stage renal disease. Second, there is no evidence of the prevention of thrombosis in mechanical heart valves.

    2012-01-01

    Postgraduate courses in clinical pharmacology are important for dentists to be updated on drug therapy and information related to their clinical practice, as well as knowledge of relevant adverse effects and interactions. A traditional approach with classroom delivery as the only method to teaching and learning has shortcomings regarding flexibility, individual learning preferences, and problem based learning (PBL) activities compared to online environments. This study examines a five week postgraduate course in clinical pharmacology with 15 hours of lectures and online learning activities, i.e. blended course design. Six postgraduate dental students participated and at the end of the course they were interviewed. Our findings emphasize that a blended learning course design can be successfully used in postgraduate dental education. Key matters for discussion were time flexibility and location convenience, change in teacher's role, rein-forced learning strategies towards professional needs, scarcity in online communication, and proposed future utilization of e-learning components.

    2014-01-01

    Full Text Available Jatropha gossypiifolia L. (Euphorbiaceae, widely known as “bellyache bush,” is a medicinal plant largely used throughout Africa and America. Several human and veterinary uses in traditional medicine are described for different parts and preparations based on this plant. However, critical reviews discussing emphatically its medicinal value are missing. This review aims to provide an up-to-date overview of the traditional uses, as well as the phytochemistry, pharmacology, and toxicity data of J. gossypiifolia species, in view of discussing its medicinal value and potential application in complementary and alternative medicine. Pharmacological studies have demonstrated significant action of different extracts and/or isolated compounds as antimicrobial, anti-inflammatory, antidiarrheal, antihypertensive, and anticancer agents, among others, supporting some of its popular uses. No clinical trial has been detected to date. Further studies are necessary to assay important folk uses, as well as to find new bioactive molecules with pharmacological relevance based on the popular claims. Toxicological studies associated with phytochemical analysis are important to understand the eventual toxic effects that could reduce its medicinal value. The present review provides insights for future research aiming for both ethnopharmacological validation of its popular use and its exploration as a new source of herbal drugs and/or bioactive natural products.

  9. Clinical review on RIT

    International Nuclear Information System (INIS)

    Full text of publication follows. Radioimmunotherapy (RIT) has been in use for more than 20 years and has progressed significantly with the discovery of new molecular targets, the development of new stable chelates, the humanization of monoclonal antibodies (MAbs), and the use of pre-targeting techniques. Today, 2 products targeting the CD20 antigen are approved in the treatment of B lymphoma: 131-tositumomab (Bexxar) and 90Y-ibritumomab tiuxetan (Zevalin). RIT can be applied in clinical practice for patients with relapsed or refractory follicular lymphoma (FL) or as consolidation after induction chemotherapy in front-line treatment in FL patients. Hematological toxicity is the major side effect of RIT and depends on bone marrow involvement and prior treatment. High-dose treatment, RIT as consolidation, RIT in first-line treatment, fractionated RIT and use of new humanized MAbs, in particular targeting CD22, showed promising results in B lymphoma. Targeting of antigens other than CD20 appears particularly interesting in the context of consolidation therapy after rituximab-based therapy. In other hemopathies, such as multiple myeloma (MM), RIT efficacy has been suggested in preclinical studies. Syndecan-1 is expressed in all MM and preclinical studies showed promising results using 213Bi-labeled anti-CD138. In solid tumors, more resistant to radiations and less accessible to large molecules such as MAbs, clinical efficacy remains limited. However, RIT used in minimal or small-size metastatic disease has shown promising clinical efficacy. Pre-targeting approaches have shown potential in increasing the therapeutic index of radiolabeled antibodies. Recently, a phase II clinical trial showed efficacy of anti-CEA pre targeted 131I-RIT in 42 progressive medullary thyroid carcinoma patients. Disease control according RECIST criteria (objective response + stabilization) was observed in 32 patients (76.2%), including one durable CR of at least 40 months and 31 durable

METHODOLOGY/PRINCIPAL FINDINGS: We performed a systematic review and meta-analysis of the literature from April 2002 to April 2008, searching MEDLINE, Cochrane, Scielo and CRISP electronic databases and reference lists from retrieved studies and conference abstracts. We used the keywords placebo and depression and escitalopram for pharmacological studies; and transcranial magnetic stimulation and depression and sham for non-pharmacological studies. All randomized, double-blinded, placebo-controlled, parallel articles on major depressive disorder were included. Forty-one studies met our inclusion criteria - 29 in the rTMS arm and 12 in the escitalopram arm. We extracted the mean and standard values of depression scores in the placebo group of each study. Then, we calculated the pooled effect size for escitalopram and rTMS arm separately, using Cohen's d as the measure of effect size. We found that placebo response are large for both escitalopram (Cohen's d - random-effects model - 1.48; 95%C.I. 1.26 to 1.6 and rTMS studies (0.82; 95%C.I. 0.63 to 1. Exploratory analyses show that sham response is associated with refractoriness and with the use of rTMS as an add-on therapy, but not with age, gender and sham method utilized. CONCLUSIONS/SIGNIFICANCE: We confirmed that placebo response in MDD is large regardless of the intervention and is associated with depression refractoriness and treatment combination (add-on rTMS studies. The magnitude of the placebo response seems to be related with study population and study design rather than the intervention

    2014-01-01

    Full Text Available Gambling disorder (GD is a psychiatric condition associated with both social and family costs; DSM-5 currently includes GD among addictive disorders. Despite the high burden of this condition, to date there are no treatment guidelines approved by Food and Drug Administration (FDA. Purpose of this paper is to offer a qualitative overview about the different pharmacologic agents used for the treatment of GD. Our analysis, conducted on a final selection of 75 scientific papers, demonstrates that a variety of pharmaceutical classes have been utilised, with different results. Published data, although limited by brief duration of the studies and small number of enrolled subjects, shows mixed evidence for serotonergic antidepressants, opioid antagonists, and mood stabilizers. Other compounds, such as glutamatergic agents and psychostimulants, deserve further studies.

    Adult Attention Deficit Hyperactivity Disorder (ADHD) is a prevalent psychiatric condition associated with high disability and frequent comorbidity. Current standard pharmacotherapy (methylphenidate and atomoxetine) improves ADHD symptoms in the short-term, but poor data were published about long-term treatment. In addition a number of patients present partial or no response to methylphenidate and atomoxetine. Research into the main database sources has been conducted to obtain an overview of alternative pharmacological approaches in adult ADHD patients. Among alternative compounds, amphetamines (mixed amphetamine salts and lisdexamfetamine) have the most robust evidence of efficacy, but they may be associated with serious side effects (e.g. psychotic symptoms or hypertension). Antidepressants, particularly those acting as noradrenaline or dopamine enhancers, have evidence of efficacy, but they should be avoided in patients with comorbid bipolar disorder. Finally metadoxine and lithium may be particularly suitable in case of comorbid alcohol misuse or bipolar disorder. PMID:26693882

    Background  Insomnia is a very common condition in various populations. Non-pharmacological interventions might offer (safe) alternatives for hypnotics. Aim  To evaluate the evidence for efficacy from systematic reviews about non-pharmacological interventions to improve sleep quality in insomnia by a systematic review of systematic reviews and meta-analyses. Search strategy  Search strategies were conducted in the Database of Abstracts of Reviews of Effects (2002-July 2008), The Cochrane Database of Systematic Reviews (2000-July 2008) and PubMed (1950-July 2008). Sleep quality was the outcome measure of interest. Selection criteria  Systematic reviews about the efficacy of one or more non-pharmacological interventions for insomnia, concerning both adult and elderly populations, were included. Reviews that included studies performed among populations suffering with severe neurological or cognitive impairments or with addictive disorders were excluded. Data analysis  Relevant data were extracted. The quality of the reviews found was appraised by using the Overview Quality Assessment Questionnaire. The evidence was appraised and divided into six classes. Results and conclusions  Sixteen reviews about 17 interventions were included. Six reviews were of adequate methodological quality. Of these, only one provided an effect size: a moderate effect was found for music-assisted relaxation. Weak evidence indicating a large effect was found for multicomponent cognitive behavioural therapy, progressive muscle relaxation, stimulus control and 'behavioural only'. Weak evidence indicating a moderate effect was found for paradoxical intention. Finally, weak evidence indicating a moderate to large effect was found for relaxation training. Because of the lack of sufficient methodological quality and the lack of calculated effect sizes, most of the included reviews were not suitable for drawing rigorous conclusions about the effect of non-pharmacological interventions on

    2012-07-01

    Full Text Available Background: Awareness about animal ethics is increasing everywhere. This increased awareness coupled with strict regulations discouraging the use of animals for routine experiments have tied the hands of many pharmacologists. They are now forced to develop alternative experiments without using animals. At present, there is acute need to come out with more innovative and useful practical exercises for pharmacology practical sessions. In this background, the present study was undertaken to develop the much-needed alternative experiments. Aims and Objective: To identify new pharmacological practical skills useful for good clinical practice. Material and Methods: A pre-tested questionnaire was administered to 110 doctors of different categories like house surgeons, postgraduate students, assistant professors and professors who are working in a tertiary care hospital. They were asked to give their suggestions regarding new pharmacology practical skills useful for good clinical practice. Statistical analysis: Responses of the participants to the questions asked were tabulated and analyzed. Suggestions given by them were listed out and studied. Results: Use of emergency drugs, dosage calculation, drugs used in pregnancy, case discussions and prescription writing exercises received a lot of support from the participants. Research methodology, cost calculation, animal experiments and interpretation of data of animal experiments did not receive support from the participants. Suggestions given by the participants regarding useful pharmacological skills belonged to the areas like therapeutics, safe use of drugs, recent advances, analysis of information given by the medical representatives and analyzing articles in journals for knowing the efficacy of drugs. Conclusion: Exercises relevant to the clinical practice, as identified in this study, can be introduced as practical pharmacology exercises. Steps are to be taken to highlight the importance of research

    A large number of studies have provided evidence for the efficacy of psychological and other non-pharmacological interventions in the treatment of chronic pain. While these methods are increasingly used to treat pain, remarkably few studies focused on the exploration of their neural correlates. The aim of this article was to review the findings from neuroimaging studies that evaluated the neural response to distraction-based techniques, cognitive behavioral therapy (CBT), clinical hypnosis, mental imagery, physical therapy/exercise, biofeedback, and mirror therapy. To date, the results from studies that used neuroimaging to evaluate these methods have not been conclusive and the experimental methods have been suboptimal for assessing clinical pain. Still, several different psychological and non-pharmacological treatment modalities were associated with increased pain-related activations of executive cognitive brain regions, such as the ventral- and dorsolateral prefrontal cortex. There was also evidence for decreased pain-related activations in afferent pain regions and limbic structures. If future studies will address the technical and methodological challenges of today's experiments, neuroimaging might have the potential of segregating the neural mechanisms of different treatment interventions and elucidate predictive and mediating factors for successful treatment outcomes. Evaluations of treatment-related brain changes (functional and structural) might also allow for sub-grouping of patients and help to develop individualized treatments. PMID:22445888

    Full Text Available Medicinal plants, since times immemorial, have been used in virtually all cultures for therapeutic purposes. The widespread use of herbal remedies and healthcare preparations obtained from commonly used traditional herbs and medicinal plants have been traced to the occurrence of natural products with medicinal properties. In the present review, an attempt has been made to collect the botanical, phytochemical, ethnomedicinal, pharmacological and toxicological information on Melia azedarach L. which is used traditionally as an anthelmintic, diuretic, emmenagouge, expectorant, vermifuge, used in piles, used as astringent, used in hysteria, leprosy, and in scrofula. Medicinally it has been shown to possess various pharmacological activities like antifungal, anti-malarial, antibacterial, hepatoprotective, anti-oxidant, anti-fertility, anthelmintic, antipyretic and cytotoxic activities. The available literature on the M. azedarach L. revealed that this plant contains many phytochemical constituents including alkaloids, terpenoids, saponins, glycosides, phenolic compounds, flavonoids and rutins. The aim of this article is to review those medicinal and pharmacological properties of M. azedarach which have been or still are being learned. The present review is therefore, an effort to give a detailed survey of the literature on its traditional, phytochemical and pharmacological properties.

    Hibiscus sabdariffa L. (Hs, roselle; Malvaceae) has been used traditionally as a food, in herbal drinks, in hot and cold beverages, as a flavouring agent in the food industry and as a herbal medicine. In vitro and in vivo studies as well as some clinical trials provide some evidence mostly for phytochemically poorly characterised Hs extracts. Extracts showed antibacterial, anti-oxidant, nephro- and hepato-protective, renal/diuretic effect, effects on lipid metabolism (anti-cholesterol), anti-diabetic and anti-hypertensive effects among others. This might be linked to strong antioxidant activities, inhibition of α-glucosidase and α-amylase, inhibition of angiotensin-converting enzymes (ACE), and direct vaso-relaxant effect or calcium channel modulation. Phenolic acids (esp. protocatechuic acid), organic acid (hydroxycitric acid and hibiscus acid) and anthocyanins (delphinidin-3-sambubioside and cyanidin-3-sambubioside) are likely to contribute to the reported effects. More well designed controlled clinical trials are needed which use phytochemically characterised preparations. Hs has an excellent safety and tolerability record. PMID:25038696

    This review summarises clinical pharmacological aspects of thiopurines in the treatment of chronic inflammatory bowel disease (IBD). Current knowledge of pharmacogenetically guided dosing is discussed for individualisation of thiopurine therapy, particularly to avoid severe adverse effects. Both azathioprine and mercaptopurine are pro-drugs that undergo extensive metabolism. The catabolic enzyme thiopurine S-methyltransferase (TPMT) is polymorphically expressed, and currently 23 genetic variants have been described. On the basis of an excellent phenotype-genotype correlation for TPMT, genotyping has become a safe and reliable tool for determination of a patient's individual phenotype. Thiopurine-related adverse drug reactions are frequent, ranging from 5% up to 40%, in both a dose-dependent and -independent manner. IBD patients with low TPMT activity are at high risk of developing severe haematotoxicity if pharmacogenetically guided dosing is not performed. Based on several cost-benefit analyses, assessment of TPMT activity is recommended prior to thiopurine therapy in patients with IBD. The underlying mechanisms of azathioprine/mercaptopurine-related hepatotoxicity, pancreatitis and azathioprine intolerance are still unknown. Although the therapeutic response appears to be related to 6-thioguanine nucleotide (6-TGN) concentrations above a threshold of 230-260 pmol per 8 x 10(8) red blood cells, at present therapeutic drug monitoring of 6-TGN can be recommended only to estimate patients' compliance.Drug-drug interactions between azathioprine/mercaptopurine and aminosalicylates, diuretics, NSAIDs, warfarin and infliximab are discussed. The concomitant use of allopurinol without dosage adjustment of azathioprine/mercaptopurine leads to clinically relevant severe haematotoxicity due to elevated thiopurine levels. Several studies indicate that thiopurine therapy in IBD during pregnancy is safe. Thus, azathioprine/mercaptopurine should not be withdrawn in strictly

    2004-01-01

    To improve the transition from research to development a critical evaluation of the individual project by research and disease area teams is required to include input from pharmacology, toxicology, pharmacokinetics, galenics, clinical pharmacology, clinical as well as regulatory experts and marketing. Decisions on the individual development strategy should be made prior to the start of development and all projects should be reviewed at predefined stages throughout the product development life cycle. This ensures consistency of decision-making not only during the development of individual products but throughout the entire development pipeline. Studies in the exploratory stage of drug development should be designed for decision making in contrast to later clinical trials in the confirmatory stage that require power for proof-of-safety and proof-of-efficacy. The more thorough and profound studies have been carried out during this exploratory stage of drug development, the earlier a decision can be made on the continuation or discontinuation of further development, thus saving development time and money and assessing and considerably reducing the risk for the patients and increasing the success rate of the project in the later confirmatory effectiveness trial with an adequate number of subjects receiving the new therapy under typical conditions of use. Strategies which may be helpful to improve the quality of decisions in drug discovery and drug development are: discovery experiments should be done to critically evaluate the compound, the "killer" experiments should be done as early as possible, continuous effort on preclinical disease models is necessary to improve predictability of efficacy in patients ("humanized" research): genomic technology should be used to identify novel, disease-related targets and to characterise preclinical test systems, improvement of knowledge and experience concerning the relevance of new technologies for the clinical picture, genotyping

    Since ancient times, plants and herbal preparations have been used as medicine. Research carried out in last few decades has certified several such claims of use of several plants of traditional medicine. Popularity of Momordica charantia (MC) in various systems of traditional medicine for several ailments (antidiabetic, abortifacient, anthelmintic, contraceptive, dysmenorrhea, eczema, emmenagogue, antimalarial, galactagogue, gout, jaundice, abdominal pain, kidney (stone), laxative, leprosy, leucorrhea, piles, pneumonia, psoriasis, purgative, rheumatism, fever and scabies) focused the investigator's attention on this plant. Over 100 studies using modern techniques have authenticated its use in diabetes and its complications (nephropathy, cataract, insulin resistance), as antibacterial as well as antiviral agent (including HIV infection), as anthelmintic and abortifacient. Traditionally it has also been used in treating peptic ulcers, interestingly in a recent experimental studies have exhibited its potential against Helicobacter pylori. Most importantly, the studies have shown its efficacy in various cancers (lymphoid leukemia, lymphoma, choriocarcinoma, melanoma, breast cancer, skin tumor, prostatic cancer, squamous carcinoma of tongue and larynx, human bladder carcinomas and Hodgkin's disease). There are few reports available on clinical use of MC in diabetes and cancer patients that have shown promising results. PMID:15182917

    2016-01-01

    Unlike the vast literature on smoking cessation in adults, research in adolescents has gained significant attention only within the last decade. Even with this increase in focus, research into pharmacological aids for smoking cessation in adolescents (e.g., nicotine replacement therapy, bupropion) is a more recent phenomenon and has produced only modest results. While more extensive, much of the research on behaviorally- or psychosocially-based adolescent smoking cessation interventions has been limited by a lack of control for contact time, biochemical verification of self-reported abstinence, and/or a theoretical focus for the interventions. The MEDLINE, PubMed, PSYCInfo CINHAL and Cochrane Systematic Review databases were searched for articles relevant to adolescent smoking cessation treatment. After briefly examining the adolescent smoking cessation research prior to 2000, more recent developments in pharmacological aids and psychological treatment will be reviewed. Investigations have made progress in elucidating efficacious treatments for adolescent smokers, but much work remains to be done in both pharmacological and non-pharmacological areas of treatment. With the current state of the literature as a guide, future directions for research into smoking cessation for adolescents will be proposed. PMID:19630713

  18. Clinical Pharmacology of Paracetamol in Neonates: A Review

    Directory of Open Access Journals (Sweden)

    Gian Maria Pacifici, MD, PhD

    2015-12-01

    Paracetamol clearance is lower in neonates than in children and adults. After metabolic conversion, paracetamol is subsequently eliminated by the renal route. The main metabolic conversions are conjugation with glucuronic acid and with sulphate. In the urine of neonates sulphated paracetamol concentration is higher than the glucuronidated paracetamol level, suggesting that sulfation prevails over glucuronidation in neonates. A loading dose of 20 mg/kg followed by 10 mg/kg every 6 hours of intravenous paracetamol is suggested to achieve a compartment concentration of 11 mg/L in late preterm and term neonates. Aiming for the same target concentration, oral doses are similar with rectal administration of 25 to 30 mg/kg/d in preterm neonates of 30 weeks’ gestation, 45 mg/kg/d in preterm infants of 34 weeks’ gestation, and 60 mg/kg/d in term neonates are suggested. The above-mentioned paracetamol doses for these indications (pain, fever are well tolerated in neonates, but do not result in a significant increase in liver enzymes, and do not affect blood pressure and have limited effects on heart rate. In contrast, the higher doses suggested in extreme preterm neonates to induce closure of the patent ductus arteriosus have not yet been sufficiently evaluated regarding efficacy or safety. Moreover, focussed pharmacovigilance to explore the potential causal association between paracetamol exposure during perinatal life and infancy and subsequent atopy is warranted.

    Racecadotril (acetorphan) is a neutral endopeptidase (NEP) inhibitor with known antidiarrheal activity in animals and humans; however, in humans, it suffers from shortcomings that might be improved with newer drugs in this class that have progressed to the clinic for nonenteric disease indications. To identify potentially superior NEP inhibitors with immediate clinical utility for diarrhea treatment, we compared their efficacy and pharmacologic properties in a rat intestinal hypersecretion model. Racecadotril and seven other clinical-stage inhibitors of NEP were obtained or synthesized. Enzyme potency and specificity were compared using purified peptidases. Compounds were orally administered to rats before administration of castor oil to induce diarrhea. Stool weight was recorded over 4 hours. To assess other pharmacologic properties, select compounds were orally administered to normal or castor oil-treated rats, blood and tissue samples collected at multiple time points, and active compound concentrations determined by mass spectroscopy. NEP enzyme activity was measured in tissue homogenates. Three previously untested clinical NEP inhibitors delayed diarrhea onset and reduced total stool output, with little or no effect on intestinal motility assessed by the charcoal meal test. Each was shown to be a potent, highly specific inhibitor of NEP. Each exhibited greater suppression of NEP activity in intestinal and nonintestinal tissues than did racecadotril and sustained this inhibition longer. These results suggest that newer clinical-stage NEP inhibitors originally developed for other indications may be directly repositioned for treatment of acute secretory diarrhea and offer advantages over racecadotril, such as less frequent dosing and potentially improved efficacy.

    This study examined the use of psychiatric medications in 277 adolescents in treatment for alcohol use disorders. Subjects were recruited from addictions treatment sites, psychiatric programs, and juvenile justice settings. Characteristics studied included the use of and indications for specific medications, changes in clinical practices from 1991 through 2000, and continuation of psychopharmacological treatment over a 1-year followup period. Among adolescents taking psychiatric medications at baseline (n = 51), indicated DSM-IV mental disorders were typically present, use of antidepressants was most common (n = 41), benzodiazepine prescription was rare, and about one third reported continuing pharmacological treatment at one-year followup. In those with comorbid major depressive disorder and alcohol use disorders (n = 110), antidepressant medication use increased significantly from 18% to 55% over the decade studied. The treatment setting did not significantly influence antidepressant prescribing practices. The common and increasing use of psychiatric medications in this population emphasizes the urgent need for empirically based clinical guidelines. PMID:14693259

    Medical students do not perform well in writing prescriptions, and the 3 variables-learner, teacher, and instructional method-are held responsible to various degrees. The objective of this clinical pharmacology educational intervention was to improve medical students' perceptions, motivation, and participation in prescription-writing sessions. The study participants were second-year medical students of the College of Medicine and Medical Sciences of the Arabian Gulf University, Bahrain. Two prescription-writing sessions were conducted using clinical case scenarios based on problems the students had studied as part of the problem-based learning curriculum. At the end of the respiratory system subunit, the training was conducted in small groups, each facilitated by a tutor. At the end of the cardiovascular system subunit, the training was conducted in a traditional large-group classroom setting. Data were collected with the help of a questionnaire at the end of each session and a focus group discussion. A majority of the students (95.3% ± 2.4%) perceived the small-group method better for teaching and learning of all aspects of prescription writing: analyzing the clinical case scenario, applying clinical pharmacology knowledge for therapeutic reasoning, using a formulary for searching relevant prescribing information, and in writing a complete prescription. Students also endorsed the small-group method for better interaction among themselves and with the tutor and for the ease of asking questions and clarifying doubts. In view of the principles of adult learning, where motivation and interaction are important, teaching and learning prescription writing in small groups deserve a serious consideration in medical curricula.

    Origanum onites L., known as Turkish oregano, has great traditional, medicinal, preservative, and commercial importance. It is used for the treatment of several kinds of ailments, such as gastrointestinal disorders, diabetes, high cholesterol, leukemia, bronchitis, etc. In this review, traditional use, phytochemistry, and pharmacology of O. onites reported between 1988 and 2014 were discussed. This review was prepared based on literature survey on scientific journals and books from libraries and electronic sources, such as Web of Science, PubMed, Scopus, Google Scholar, etc. All databases were searched up to June 2014. Several different classes of terpenoids, triterpene acids, phenolic acids, hydroquinones, flavonoids, hydrocarbons, sterols, pigments, fatty acids, tocopherols, and inorganic compounds were detected mainly in the aerial parts of this plant. Pharmacological studies revealed that extracts obtained from several solvents and individual compounds exhibited antimicrobial, antiviral, antioxidant, insecticidal, anticancer, hepatoprotective, genotoxic, antidiabetic, cholinesterase inhibitory, anti-inflammatory, analgesic activities, etc. O. onites, in general, exhibited remarkable activity potential in almost all test systems. The results of toxicity studies indicated that O. onites did not show any significant toxicity and mutagenicity on Drosophila and Salmonella. Toxicity of the extracts/essential oils and also individual compounds should be evaluated on mammalian cells to ensure their safety. The bioactivity of individual compounds aside from terpenoids should also be assessed in detail. Additionally, mode of action for the bioactive compounds should be evaluated to understand the complex pharmacological effects of these phytochemicals. PMID:27062715

    Present review for the first time provides a complete botanical description and information on ethnomedicinal uses of Clerodendron glandulosum.Coleb (CG;Fam, Verbenaceae). Recent studies conducted from our laboratory provide pharmacological evidence for its anti-hypertensive, anti-diabetic and anti-obesity potentials. Further, its beneficial potential in preventing in vitro and in vivo non-alcoholic steatohepatitis and atherosclerosis and potent hepatoprotective and free radical scavenging abilities along with its acute and sub-chronic toxicological evaluations are also reported from our laboratory. In keeping with its traditional uses, CG extract was capable of ameliorating experimentally induced hypertension, diabetes and obesity. Its beneficial potential against NASH induced oxidative stress and atherosclerosis can be attributed to its potent free radical scavenging potential. Non-toxic nature of CG leaf extract further provides added merit to its reported pharmacological properties. The present review summarizes the pioneering scientific evidence for the pharmacological effects of CG against related metabolic disorders like hypertension, diabetes and obesity along with anti oxidant potential and beneficial effects against non alcoholic steatohepatitis.

    Pharmacologic agents to promote mucus clearance may reduce the sequelae of obstructive secretions. We systematically reviewed comparative studies of pharmacologic agents for mucus clearance in hospitalized or postoperative subjects without cystic fibrosis and over 12 months of age. We searched MEDLINE and other databases from January 1970 to July 2014 to identify relevant literature. Two reviewers independently assessed each study against predetermined inclusion/exclusion criteria. Two reviewers also independently extracted data regarding subject and intervention characteristics and outcomes and assigned overall quality ratings. The 9 studies meeting review criteria included 5 randomized controlled trials, 3 crossover randomized controlled trials, and one retrospective cohort study. Studies were small and together included a total of 379 subjects (mean of 42 subjects per study). N-acetylcysteine, heparin plus N-acetylcysteine, albuterol, ipratropium bromide, and saline were assessed. Studies reported no benefit of studied agents on expectoration, pulmonary function, and atelectasis and little effect on changes in sputum volume, weight, or viscosity. Adverse effects of agents were not consistently reported. Nausea was reported in 2 studies of N-acetylcysteine (one paper reported 2 experiments and did not clearly identify in which experiment adverse effects occurred), 3 studies reported that there were no adverse events, and 3 studies did not address adverse effects at all. Further research with clearly characterized populations and interventions is needed to understand the potential benefits and adverse effects of mucoactive agents. PMID:25944943

    To review the literature on epidemiology, clinical features, diagnostic imaging, natural history, management, therapeutic approaches, and prognosis of myopic foveoschisis. A systematic Pubmed search was conducted using search terms: myopia, myopic, staphyloma, foveoschisis, and myopic foveoschisis. The evidence base for each section was organised and reviewed. Where possible an authors' interpretation or conclusion is provided for each section. The term myopic foveoschisis was first coined in 1999. It is associated with posterior staphyloma in high myopia, and is often asymptomatic initially but progresses slowly, leading to loss of central vision from foveal detachment or macular hole formation. Optical coherence tomography is used to diagnose the splitting of the neural retina into a thicker inner layer and a thinner outer layer, but compound variants of the splits have been identified. Vitrectomy with an internal limiting membrane peel and gas tamponade is the preferred approach for eyes with vision decline. There has been a surge of new information on myopic foveoschisis. Advances in optical coherence tomography will continually improve our understanding of the pathogenesis of retinal splitting, and the mechanisms that lead to macular damage and visual loss. Currently, there is a good level of consensus that surgical intervention should be considered when there is progressive visual decline from myopic foveoschisis. PMID:25744445

    Full Text Available Abstract Background Non-pharmacological treatment (NPT is a useful treatment option in the management of hip or knee osteoarthritis. To our knowledge however, no studies have investigated the effect of NPT in patients with generalized osteoarthritis (GOA. The primary aim of this study is to compare the effectiveness of two currently existing health care programs with different intensity and mode of delivery on daily functioning in patients with GOA. The secondary objective is to compare the cost-effectiveness of both interventions. Methods/Design In this randomized, single blind, clinical trial with active controls, we aim to include 170 patients with GOA. The experimental intervention consist of six self-management group sessions provided by a multi-disciplinary team (occupational therapist, physiotherapist, dietician and specialized nurse. The active control group consists of two group sessions and four sessions by telephone, provided by a specialized nurse and physiotherapist. Both therapies last six weeks. Main study outcome is daily functioning during the first year after the treatment, assessed on the Health Assessment Questionnaire. Secondary outcomes are health related quality of life, specific complaints, fatigue, and costs. Illness cognitions, global perceived effect and self-efficacy, will also be assessed for a responder analysis. Outcome assessments are performed directly after the intervention, after 26 weeks and after 52 weeks. Discussion This article describes the design of a randomized, single blind, clinical trial with a one year follow up to compare the costs and effectiveness of two non-pharmacological interventions with different modes of delivery for patients with GOA.

    Full Text Available Biogenic amines are a collection of endogenous molecules that play pivotal roles as neurotransmitters and hormones. In addition to the classical biogenic amines resulting from decarboxylation of aromatic acids, including dopamine (DA, norepinephrine, epinephrine, serotonin (5-HT and histamine, other biogenic amines, present at much lower concentrations in the central nervous system (CNS, and hence referred to as trace amines (TAs, are now recognized to play significant neurophysiological and behavioural functions. At the turn of the century, the discovery of the trace amine-associated receptor 1 (TAAR1, a phylogenetically conserved G protein-coupled receptor that is responsive to both TAs, such as β-phenylethylamine, octopamine and tyramine, and structurally-related amphetamines, unveiled mechanisms of action for TAs other than interference with aminergic pathways, laying the foundations for deciphering the functional significance of TAs and its mammalian CNS receptor, TAAR1. Although its molecular interactions and downstream targets have not been fully elucidated, TAAR1 activation triggers accumulation of intracellular cAMP, modulates PKA and PKC signalling and interferes with the β-arrestin2-dependent pathway via G protein-independent mechanisms. TAAR1 is uniquely positioned to exert direct control over DA and 5-HT neuronal firing and release, which has profound implications for understanding the pathophysiology of, and therefore designing more efficacious therapeutic interventions for, a range of neuropsychiatric disorders that involve aminergic dysregulation, including Parkinson’s disease, schizophrenia, mood disorders and addiction. Indeed, the recent development of novel pharmacological tools targeting TAAR1 has uncovered the remarkable potential of TAAR1-based medications as new generation pharmacotherapies in neuropsychiatry. This review summarizes recent developments in the study of TAs and TAAR1, their intricate neurochemistry and

In addition to the "classical" biogenic amines resulting from decarboxylation of aromatic acids, including dopamine (DA), norepinephrine, epinephrine, serotonin (5-HT), and histamine, other biogenic amines, present at much lower concentrations in the central nervous system (CNS), and hence referred to as "trace" amines (TAs), are now recognized to play significant neurophysiological and behavioral functions. At the turn of the century, the discovery of the trace amine-associated receptor 1 (TAAR1), a phylogenetically conserved G protein-coupled receptor that is responsive to both TAs, such as β-phenylethylamine, octopamine, and tyramine, and structurally-related amphetamines, unveiled mechanisms of action for TAs other than interference with aminergic pathways, laying the foundations for deciphering the functional significance of TAs and its mammalian CNS receptor, TAAR1. Although, its molecular interactions and downstream targets have not been fully elucidated, TAAR1 activation triggers accumulation of intracellular cAMP, modulates PKA and PKC signaling and interferes with the β-arrestin2-dependent pathway via G protein-independent mechanisms. TAAR1 is uniquely positioned to exert direct control over DA and 5-HT neuronal firing and release, which has profound implications for understanding the pathophysiology of, and therefore designing more efficacious therapeutic interventions for, a range of neuropsychiatric disorders that involve aminergic dysregulation, including Parkinson's disease, schizophrenia, mood disorders, and addiction. Indeed, the recent development of novel pharmacological tools targeting TAAR1 has uncovered the remarkable potential of TAAR1-based medications as new generation pharmacotherapies in neuropsychiatry. This review summarizes recent developments in the study of TAs and TAAR1, their intricate neurochemistry and

    We have traced the historical link between the Law of Mass Action and clinical pharmacology. The Law evolved from the work of the French chemist Claude Louis Berthollet, was first formulated by Cato Guldberg and Peter Waage in 1864 and later clarified by the Dutch chemist Jacobus van 't Hoff in 1877. It has profoundly influenced our qualitative and quantitative understanding of a number of physiological and pharmacological phenomena. According to the Law of Mass Action, the velocity of a chemical reaction depends on the concentrations of the reactants. At equilibrium the concentrations of the chemicals involved bear a constant relation to each other, described by the equilibrium constant, K. The Law of Mass Action is relevant to various physiological and pharmacological concepts, including concentration-effect curves, dose-response curves, and ligand-receptor binding curves, all of which are important in describing the pharmacological actions of medications, the Langmuir adsorption isotherm, which describes the binding of medications to proteins, activation curves for transmembrane ion transport, enzyme inhibition and the Henderson-Hasselbalch equation, which describes the relation between pH, as a measure of acidity and the concentrations of the contributory acids and bases. Guldberg and Waage recognized the importance of dynamic equilibrium, while others failed to do so. Their ideas, over 150 years old, are embedded in and still relevant to clinical pharmacology. Here we explain the ideas and in a subsequent paper show how they are relevant to understanding adverse drug reactions. PMID:26174880

  8. How should training of graduates in clinical pharmacology and therapeutics be delivered and assessed?

    The UK postgraduate curriculum in clinical pharmacology and therapeutics (CPT) incorporates the common competencies required of all physicians and shows how trainees from other specialties, including primary care, can train in CPT. Various models of training and assessment are possible. Evolution of the current system to meet new challenges would maintain an established tradition, with a ready source of training funds. However, this would require greater input from all consultants in CPT, including the training and assessment of trainees. A joint venture with the Faculty of Pharmaceutical Medicine would have the advantage, if the Faculty agreed, of introducing ready-made curriculum modules and assessment tools that have been accepted by the General Medical Council. However, extra modules relevant to CPT would have to be constructed to complement the common areas already in the pharmaceutical medicine curriculum, and there would be a perceived loss of the independence that clinical pharmacologists currently enjoy when making decisions about manufacturers' products. Abandoning externally approved training in CPT would allow the specialty to devise its own training and assessment in the necessary skills. Critically, however, this would impair the status of the specialty and would incur loss of financial support from postgraduate Deaneries. To attract high-calibre trainees, we must completely define CPT training and assessment structures. Most clinical pharmacologists seem to prefer to allow the current structures to evolve under external guidance. However, this will not succeed unless all trained clinical pharmacologists contribute to development of both the curriculum and specific assessment tools, and open their teaching and assessment skills to scrutiny.

    Fumaria indica (Hausskn.) Pugsley (Fumariaceae), known as “Fumitory”, is an annual herb found as a common weed all over the plains of India and Pakistan. The whole plant is widely used in traditional and folkloric systems of medicine. In traditional systems of medicine, the plant is reputed for its anthelmintic, diuretic, diaphoretic, laxative, cholagogue, stomachic and sedative activities and is used to purify blood and in liver obstruction in ethnopharmacology. The whole plant is ascribed to possess medicinal virtues in Ayurvedic and Unani systems of medicine and is also used in preparation of important Ayurvedic medicinal preparations and polyherbal liver formulations. The review reveals that phytochemical constituents of wide range have been separated from the plants and it possesses important pharmacological activities like smooth muscle relaxant, spasmogenic and spasmolytic, analgesic, anti-inflammatory, neuropharmacological and antibacterial activities. The separation of hepatoprotective and antifungal constituents from this plant was also reported newly. This review highlights the traditional, ethnobotanical, phytochemical, pharmacological information available on Fumaria indica, which might be helpful for scientists and researchers to find out new chemical entities responsible for its claimed traditional uses.

    MDMA-induced hyperthermia is highly variable, unpredictable, and greatly potentiated by the social and environmental conditions of recreational drug use. Current strategies to treat pathological MDMA-induced hyperthermia in humans are palliative and marginally effective, and there are no specific pharmacological treatments to counteract this potentially life-threatening condition. Here, we tested the efficacy of mixed adrenoceptor blockers carvedilol and labetalol, and the atypical antipsychotic clozapine, in reversing MDMA-induced brain and body hyperthermia. We injected rats with a moderate non-toxic dose of MDMA (9 mg/kg) during social interaction, and we administered potential treatment drugs after the development of robust hyperthermia (>2.5 °C), thus mimicking the clinical situation of acute MDMA intoxication. Brain temperature was our primary focus, but we also simultaneously recorded temperatures from the deep temporal muscle and skin, allowing us to determine the basic physiological mechanisms of the treatment drug action. Carvedilol was modestly effective in attenuating MDMA-induced hyperthermia by moderately inhibiting skin vasoconstriction, and labetalol was ineffective. In contrast, clozapine induced a marked and immediate reversal of MDMA-induced hyperthermia via inhibition of brain metabolic activation and blockade of skin vasoconstriction. Our findings suggest that clozapine, and related centrally acting drugs, might be highly effective for reversing MDMA-induced brain and body hyperthermia in emergency clinical situations, with possible life-saving results.

    The genus Marrubium (Lamiaceae) is comprised of about forty species, distributed in Europe, Asia and Brazil. Some species are traditionally used to treat various diseases, including asthma, pulmonary infections, inflammation and hypotension, as cholagogues and sedative agents, and for pain relief. A literature review on the chemical and biological aspects of these plants indicates antimicrobial activity against gram positive bacteria, analgesic properties, and anti-hypertensive, antidiabetic, antioxidant properties, among others, particularly related to the presence of diterpenes, sterols, phenylpropanoids and flavonoids. This review shows the main chemical and pharmacological aspects of the genus Marrubium, with emphasis on M. vulgare, which grows in Brazil and has been studied by us and other authors. PMID:20942795

  12. Clinical review of mucoepidermoid carcinomas

    International Nuclear Information System (INIS)

    Mucoepidermoid carcinoma is a rare head and neck cancer tumor, composed of both mucous and epidermoid cells. We retrospectively reviewed the case of 36 such patients hospitalized in the last 24 years (between 1978 and 2002) at Kurume University Hospital, focusing on origin, treatment, and treatment outcome. In this study, 33 patients undergoing currative treatment were studied in detail. Tumors originated in major salivary glands in 24 and in the oral cavity, paranasal cavity, and oropharynx in 3 each. Salivary gland carcinomas were graded, clinically and histopathologically based on the criteria of Goode et al. as follows: low (n=3), intermediate (n=3), and high (n=18). All patients underwent radical surgery. Lymph node metastasis was detected in 9, distant metastasis in 6 (lung: 4; liver: 1; bone: 1), and local recurrence in 5 patients. Lymph node recurrence was detected in 3. Survival was calculated with Kaplan-Meier's methods. Five-year overall survival was 64%, i.e., 56% in salivary gland malignancy, 67% in oral cavity malignancy, 100% in paranasal cavity malignancy and 100% in oropharyax malignancy. Five-year survival was 76% in T2, 75% in T3, 51% in T4. Five-year survival in N0 was 80% and 22% in N+ cases, with a statistically significant difference (p<0.05). Five-year survival was 71% in stage I, 83% in stage II, and 54% in stage IV. Five-year survival in low and intermediate grade was 100%, whereas that in high grade was 43%. The 21 patients undergoing modified neck dissection has a 5-year survival of 52%. In 20 patients undergoing postoperative radiotherapy, 4 died of local recurrence. In 31 patients not undergoing chemotherapy, 6 died of distant metastasis. These results emphasize the necessity of radiotherapy and chemotherapy after surgical treatment for head and neck mucoepidermoid carcinoma. (author)

    The current treatment of Parkinson's disease with dopamine-centric approaches such as L-DOPA and dopamine agonists, although very successful, is in need of alternative treatment strategies, both in terms of disease modification and symptom management. Various non-dopaminergic treatment approaches did not result in a clear clinical benefit, despite showing a clear effect in preclinical animal models. In addition, polypharmacy is common, sometimes leading to unintended effects on non-motor cognitive and psychiatric symptoms. To explore novel targets for symptomatic treatment and possible synergistic pharmacodynamic effects between different drugs, we developed a computer-based Quantitative Systems Pharmacology (QSP) platform of the closed cortico-striatal-thalamic-cortical basal ganglia loop of the dorsal motor circuit. This mechanism-based simulation platform is based on the known neuro-anatomy and neurophysiology of the basal ganglia and explicitly incorporates domain expertise in a formalized way. The calculated beta/gamma power ratio of the local field potential in the subthalamic nucleus correlates well (R (2) = 0.71) with clinically observed extra-pyramidal symptoms triggered by antipsychotics during schizophrenia treatment (43 drug-dose combinations). When incorporating Parkinsonian (PD) pathology and reported compensatory changes, the computer model suggests a major increase in b/g ratio (corresponding to bradykinesia and rigidity) from a dopamine depletion of 70% onward. The correlation between the outcome of the QSP model and the reported changes in UPDRS III Motor Part for 22 placebo-normalized drug-dose combinations is R (2) = 0.84. The model also correctly recapitulates the lack of clinical benefit for perampanel, MK-0567 and flupirtine and offers a hypothesis for the translational disconnect. Finally, using human PET imaging studies with placebo response, the computer model predicts well the placebo response for chronic treatment, but not for acute

    Humans have been using natural products for medicinal use for ages. Natural products of therapeutic importance are compounds derived from plants, animals, or any microorganism. Ginger is also one of the most commonly used condiments and a natural drug in vogue. It is a traditional medicine, having some active ingredients used for the treatment of numerous diseases. During recent research on ginger, various ingredients like zingerone, shogaol, and paradol have been obtained from it. Zingerone (4-(4-hydroxy-3-methoxyphenyl)-2-butanone) is a nontoxic and inexpensive compound with varied pharmacological activities. It is the least pungent component of Zingiber officinale. Zingerone is absent in fresh ginger but cooking or heating transforms gingerol to zingerone. Zingerone closely related to vanillin from vanilla and eugenol from clove. Zingerone has potent anti-inflammatory, antidiabetic, antilipolytic, antidiarrhoeic, antispasmodic, and so forth properties. Besides, it displays the property of enhancing growth and immune stimulation. It behaves as appetite stimulant, anxiolytic, antithrombotic, radiation protective, and antimicrobial. Also, it inhibits the reactive nitrogen species which are important in causing Alzheimer's disease and many other disorders. This review is written to shed light on the various pharmacological properties of zingerone and its role in alleviating numerous human and animal diseases. PMID:26106644

    Full Text Available As aboriginal sources of medications, medicinal plants are used from the ancient times. Andrographis paniculata is one of the highly used potential medicinal plants in the world. This plant is traditionally used for the treatment of common cold, diarrhoea, fever due to several infective cause, jaundice, as a health tonic for the liver and cardiovascular health, and as an antioxidant. It is also used to improve sexual dysfunctions and serve as a contraceptive. All parts of this plant are used to extract the active phytochemicals, but the compositions of phytoconstituents widely differ from one part to another and with place, season, and time of harvest. Our extensive data mining of the phytoconstituents revealed more than 55 ent-labdane diterpenoids, 30 flavonoids, 8 quinic acids, 4 xanthones, and 5 rare noriridoids. In this review, we selected only those compounds that pharmacology has already reported. Finally we focused on around 46 compounds for further discussion. We also discussed ethnobotany of this plant briefly. Recommendations addressing extraction process, tissue culture, and adventitious rooting techniques and propagation under abiotic stress conditions for improvement of phytoconstituents are discussed concisely in this paper. Further study areas on pharmacology are also proposed where needed.

    2016-08-01

    Progressive muscle weakness and degeneration due to the lack of dystrophin eventually leads to the loss of independent ambulation by the middle of the patient's second decade, and a fatal outcome due to cardiac or respiratory failure by the third decade. More specifically, loss of sarcolemmal dystrophin and the dystrophin-associated glycoprotein (DAG) complex promotes muscle fiber damage during muscle contraction. This process results in an efflux of creatine kinase (CK), an influx of calcium ions, and the recruitment of T cells, macrophages, and mast cells to the damaged muscle, causing progressive myofiber necrosis. For the last 20 years, the major goal in the development of therapeutic approaches to alleviate muscle weakness in DMD has been centered on the restoration of dystrophin or proteins that are analogous to dystrophin, such as utrophin, through a variety of modalities including cell therapy, gene therapy, gene correction, and the highly promising techniques utilizing CRISPR/Cas9 technology. Despite the development of new therapeutic options, there still exist numerous challenges that we must face with regard to these new strategies and, consequently, we still do not have any feasible options available to ultimately slow the progression of this devastating disease. The purpose of this article is to highlight the current knowledge and advancements in the evolving paradigms in clinical pharmacology and therapeutics for this devastating musculoskeletal disease.

    1. The aim of this study has been to evaluate the response to imipramine treatment in enuretic children through the use of a series of clinical and pharmacological variables and by applying a multivariate (principal components) analysis technique. 2. The study was carried out on 146 children whose ages ranged from 5 to 14 years, and who received variable doses of imipramine (12.5 to 100 mg day-1). 3. The quantitative variables analyzed were: drug dosage, serum levels of imipramine and its metabolite desipramine, the relationship between them both, the duration of treatment, age and weight. 4. The qualitative variables were: compliance, presence of side-effects, enuretic and/or psychiatric antecedents, intelligence quotient (I.Q.), the existence (or absence) of related pathologies, sex, and the type of enuresis. 5. The response to treatment was quantified by means of the percentage of decrease in frequency of enuresis as compared with the initial frequency. 6. The results obtained show that the variables which are most associated with the reduction of enuresis are, in decreasing order: the dosage of imipramine administered, the duration of treatment, compliance and the level/dose ratio for the sum of the drug and metabolite levels.

  5. Pharmacological targeting of dopamine D3 receptors: Possible clinical applications of selective drugs.

    2015-09-01

    Dopamine D3 receptors have been pharmacologically engaged in humans since the development of the first antipsychotics and ergot-derivative dopamine (DA) agonists, even without knowing it. These agents were generally non-selective, developed primarily to target D2 receptors. In the last 10 years the understanding of the clinical implication of D3 receptors has been progressing also due to the identification of D3 gene polymorphisms, the use of more selective PET ligands such as [(11)C]-(+)-PHNO and the learning regarding the clinical use of the D3-preferential D2/D3 agonists ropinirole and pramipexole. A new specific neuroplasticity role of D3 receptor regarding dendrite arborisation outgrowth in dopaminergic neurons was also proposed to support, at least in part, the slowing of disease observed in subjects with Parkinson׳s Disease treated with DA agonists. Similar mechanisms could be at the basis of the antidepressant-like effects observed with DA agonists when co-administered with standard of care. Severe adverse event occurring with the use of anti-parkinsonian DA agonists in predisposed subjects, i.e., impulse control disorders, are now suggested to be putatively related to overactive D3 receptors. Not surprisingly, blockade of D3 receptors was proposed as treatment for addictive disorders, a goal that could be potentially achieved by repositioning buspirone, an anxiolytic drug with D3-preferential antagonistic features, or with novel selective D3 antagonists or partial agonists currently in development for schizophrenia. At the moment ABT-925 is the only selective D3 antagonist tested in schizophrenic patients in Phase II, showing an intriguing cognitive enhancing effects supported by preclinical data. Finally, exploratory pharmacogenetic analysis suggested that ABT-925 could be effective in a subpopulation of patients with a polymorphism on the D3 receptor, opening to a possible personalised medicine approach.

    As a consequence of both traditional and non-traditional risk factors, cardiovascular disease is over-represented, and the leading cause of mortality, among patients with Chronic Kidney Disease (CKD). Whilst recommendations for reducing cardiovascular risk in the general population exist, their applicability to the CKD population is questionable due to the exclusion of CKD patients from the majority of contemporary cardiovascular interventional studies. The aim of this review is to critically evaluate the literature regarding pharmacologic cardiovascular interventions in patients with CKD, with an emphasis on studies published since our 2008 review. Interventions discussed include erythropoiesis-stimulating agents (TREAT, U.S. Normal Hematocrit, CHOIR, CREATE, Palmer meta-analysis); statins (SHARP, AURORA, PPP, 4D, ALERT); Fibrates (VA-HIT); Folic Acid (ASFAST, US FOLIC acid trial, HOST); Antihypertensive Agents, Including Angiotensin-Converting Enzyme Inhibitors, angiotensin-receptor blockers, Beta-blockers and Combination therapy (Cice et al, FOSDIAL, Agarwal et al, ONTARGET); sevelamer (DCOR); Cinacalcet (ADVANCE, EVOLVE, Cunningham meta-analysis); Anti-oxidants (SPACE, HOPE, ATIC); Aspirin (HOT study re-analysis); vitamin D analogues (PRIMO); and multidisciplinary intervention (LANDMARK). Unfortunately, there remains a paucity of evidence in this area and a large number of methodologically poor quality studies with negative results. It is possible that these interventions do not have the same positive effect in CKD patients due to differences in the pathogenesis driving cardiovascular disease burden, such as altered bone metabolism and calcific vascular disease. Further well-designed studies with appropriately selected study populations and patient level outcomes are required. Until such time, physicians must consider on an individual patient basis the appropriateness of these interventions. PMID:26497837

    The objective of this review was to determine the effectiveness of pharmacological interventions [i.e., non-steroid anti-inflammatory drugs (NSAIDs), muscle relaxants, antidepressants, and opioids] for non-specific chronic low-back pain (LBP). Existing Cochrane reviews for the four interventions were screened for studies fulfilling the inclusion criteria. Then, the literature searches were updated. Only randomized controlled trials on adults (≥18 years) with chronic (≥12 weeks) non-specific LBP and evaluation of at least one of the main clinically relevant outcome measures (pain, functional status, perceived recovery, or return to work) were included. The GRADE approach was used to determine the quality of evidence. A total of 17 randomized controlled trials was included: NSAIDs (n = 4), antidepressants (n = 5), and opioids (n = 8). No studies were found for muscle relaxants; 14 studies had a low risk of bias. The studies only reported effects on the short term (after stopping their medication. However, both types of medication show more adverse effects than placebo. There seems to be no difference in effect between antidepressants and placebo in patients with non-specific chronic LBP.

  16. A review of clinical guidelines.

    LENUS (Irish Health Repository)

    Andrews, E J

    2012-02-03

    BACKGROUND: Clinical guidelines are increasingly used in patient management but few clinicians are familiar with their origin or appropriate application. METHODS: A Medline search using the terms \\'clinical guidelines\\' and \\'practice guidelines\\' was conducted. Additional references were sourced by manual searching from the bibliographies of articles located. RESULTS AND CONCLUSION: Clinical guidelines originated in the USA in the early 1980s, initially as a cost containment exercise. Significant improvements in the process and outcomes of care have been demonstrated following their introduction, although the extent of improvement varies considerably. The principles for the development of guidelines are well established but many published guidelines fall short of these basic quality criteria. Guidelines are only one aspect of improving quality and should be used within a wider framework of promoting clinical effectiveness. Understanding their limitations as well as their potential benefits should enable clinicians to have a clearer view of their place in everyday practice.

The available literature has been reviewed for motor, cognitive, and psychiatric alterations, which are the three major symptom domains of this devastating progressive disease. From a clinical point of view, one has to be aware that the HD phenotype can vary highly across individuals and during the course of the disease. Also, symptoms in juvenile HD can differ substantially from those with adult-onset of HD. Although there is no cure of HD and management is limited, motor and psychiatric symptoms often respond to pharmacotherapy, and nonpharmacological approaches as well as supportive care are essential. International treatment recommendations based on study results, critical statements, and expert opinions have been included. This review is restricted to symptomatic and supportive approaches since all attempts to establish a cure for the disease or modifying therapies have failed so far.

    2015-10-01

    Recent reports have highlighted studies in biomedical research that cannot be reproduced, tending to undermine the credibility, relevance and sustainability of the research process. To address this issue, a number of factors can be monitored to improve the overall probability of reproducibility. These include: (i) shortcomings in experimental design and execution that involve hypothesis conceptualization, statistical analysis, and data reporting; (ii) investigator bias and error; (iii) validation of reagents including cells and antibodies; and (iv) fraud. Historically, research data that have undergone peer review and are subsequently published are then subject to independent replication via the process of self-correction. This often leads to refutation of the original findings and retraction of the paper by which time considerable resources have been wasted in follow-on studies. New NIH guidelines focused on experimental conduct and manuscript submission are being widely adopted in the peer-reviewed literature. These, in their various iterations, are intended to improve the transparency and accuracy of data reporting via the use of checklists that are often accompanied by "best practice" guidelines that aid in validating the methodologies and reagents used in data generation. The present Editorial provides background and context to a newly developed checklist for submissions to Biochemical Pharmacology that is intended to be clear, logical, useful and unambiguous in assisting authors in preparing manuscripts and in facilitating the peer review process. While currently optional, development of this checklist based on user feedback will result in it being mandatory within the next 12 months. PMID:26208784

    Full Text Available Silvio Caccia, Roberto William Invernizzi, Alessandro Nobili, Luca Pasina IRCCS-Istituto di Ricerche Farmacologiche Mario Negri, Milan, Italy Abstract: Cariprazine is a potential antipsychotic awaiting approval from the US Food and Drug Administration. It is a dopamine D2- and D3-receptor partial agonist, with higher affinity for D3 receptors, as opposed to the D2 antagonism of most older antipsychotic agents. Like most lipophilic antipsychotics, it undergoes extensive hepatic metabolism by cytochrome P450 (CYP, mainly the highly variable 3A4, with the formation of active metabolites. However, the parent compound – particularly its active didesmethyl derivative – is cleared very slowly, with elimination half-lives in schizophrenic patients ranging from 2–5 days for cariprazine to 2–3 weeks for didesmethyl-cariprazine. Exposure to the latter was several times that for cariprazine, although didesmethyl-cariprazine did not reach steady state within the 3 weeks of 12.5 mg/day dosing. Preliminary information on its therapeutic role comes from press releases and a few abstracts presented at scientific meetings. In short-term controlled trials, it was more effective than placebo in reducing positive and negative symptoms of schizophrenia, with an effective dose range of 1.5–12 mg/day. Although cariprazine was associated with a higher incidence of akathisia and extrapyramidal side effects than placebo, it did not cause weight gain, metabolic abnormalities, prolactin increase, or corrected QT prolongation. Similarly, cariprazine's efficacy and tolerability for the treatment of bipolar disorder (manic/mixed and depressive episodes was established in the dose range of 3–12 mg/day, although again no long-term data are available. Well-designed clinical trials, mainly direct "head-to-head" comparisons with other second-generation antipsychotic agents, are needed to define the therapeutic role and safety profile of cariprazine in schizophrenia and

    Inflammatory demyelinating diseases comprise a spectrum of disorders affecting the myelin of the central and peripheral nervous system. These diseases can usually be differentiated on the basis of clinical, radiological, laboratory and pathological findings. Recent studies have contributed to current awareness that inflammatory demyelinating diseases are not restricted to the adult age group, but are more common in pediatric age than previously believed. Some of pediatric inflammatory demyelinating diseases carry an unfavorable long-term prognosis but appropriate treatments can improve the outcome. The possibility of physical and cognitive disability resulting from these diseases, highlights the urgent need for therapeutic strategies for neurorehabilitation, neuroregeneration, and neurorepair. This review discusses characteristics of primary demyelinating diseases more frequently observed in childhood, focusing on epidemiology, clinical aspects and treatments. PMID:21119885

    Objective To conduct a systematic review of published research on the pharmacological treatment of pain after spinal cord injury (SCI). Data Sources Medline, CINAHL, EMBASE and PsycINFO databases were searched for articles published 1980 to June 2009 addressing the treatment of pain post SCI. Randomized controlled trials (RCTs) were assessed for methodological quality using the PEDro assessment scale, while non-RCTs were assessed using the Downs and Black evaluation tool. A level of evidence was assigned to each intervention using a modified Sackett scale. Study Selection The review included randomized controlled trials and non-randomized controlled trials which included prospective controlled trials, cohort, case series, case-control, pre-post and post studies. Case studies were included only when there were no other studies found. Data Extraction Data extracted included the PEDro or Downs and Black score, the type of study, a brief summary of intervention outcomes, type of pain, type of pain scale and the study findings.. Data Synthesis Articles selected for this particular review evaluated different interventions in the pharmacological management of pain post SCI. 28 studies met inclusion criteria: there were 21 randomized controlled trials of these 19 had Level 1 evidence. Treatments were divided into five categories: anticonvulsants, antidepressants, analgesics, cannabinoids and antispasticity medications. Conclusions Most studies did not specify participants’ types of pain; hence making it difficult to identify the type of pain being targeted by the treatment. Anticonvulsant and analgesic drugs had the highest levels of evidence and were the drugs most often studied. Gabapentin and pregabalin had strong evidence (five Level 1 RCTs) for effectiveness in treating post-SCI neuropathic pain, as did intravenous analgesics (lidocaine, ketamine and morphine) but the latter only had short term benefits. Tricyclic antidepressants only showed benefit for neuropathic

To date, the most thoroughly studied non-pharmacological approaches to managing FM are those with a focus on changing patient activities and beliefs that affect the illness. These interventions are intended to facilitate enduring improvement in pain and functional status. Lifestyle-oriented treatments include patient education, aerobic or other physical exercise, and cognitive-behavioral therapy (CBT. These interventions in FM can be delivered in medical or behavioral health care settings by trained professionals, through patient-oriented treatment manuals, or via remote-access technologies. Non-pharmacological treatments, in particular exercise and CBT, have yielded effect sizes and cost–benefit ratios comparable to medications. This paper describes lifestyle-oriented non-pharmacological treatments for FM and highlights selected literature reviews of these interventions. In addition, behavioral and practical issues are addressed that may affect these non-pharmacological treatments, including patient expectations, participant burden, and treatment availability. Recommendations are made to facilitate these interventions and potentially improve outcomes. In particular, the increasing availability of convenient home-based mobile technologies to deliver these non-pharmacological treatments is described.Keywords: cognitive-behavior therapy, exercise, education, mobile technology

  10. Human Schistosomiasis: Clinical Perspective: Review

    Directory of Open Access Journals (Sweden)

    Rashad S. Barsoum

    2013-09-01

    Full Text Available The clinical manifestations of schistosomiasis pass by acute, sub acute and chronic stages that mirror the immune response to infection. The later includes in succession innate, TH1 and TH2 adaptive stages, with an ultimate establishment of concomitant immunity. Some patients may also develop late complications, or suffer the sequelae of co-infection with other parasites, bacteria or viruses. Acute manifestations are species-independent; occur during the early stages of invasion and migration, where infection-naivety and the host’s racial and genetic setting play a major role. Sub acute manifestations occur after maturity of the parasite and settlement in target organs. They are related to the formation of granulomata around eggs or dead worms, primarily in the lower urinary tract with Schistosoma haematobium, and the colon and rectum with Schistosoma mansoni, Schistosoma japonicum, Schistosoma intercalatum and Schistosoma mekongi infection. Secondary manifestations during this stage may occur in the kidneys, liver, lungs or other ectopic sites. Chronic morbidity is attributed to the healing of granulomata by fibrosis and calcification at the sites of oval entrapment, deposition of schistosomal antigen-antibody complexes in the renal glomeruli or the development of secondary amyloidosis. Malignancy may complicate the chronic lesions in the urinary bladder or colon. Co-infection with salmonella or hepatitis viruses B or C may confound the clinical picture of schistosomiasis, while the latter may have a negative impact on the course of other co-infections as malaria, leishmaniasis and HIV. Prevention of schistosomiasis is basically geared around education and periodic mass treatment, an effective vaccine being still experimental. Praziquantel is the drug of choice in the treatment of active infection by any species, with a cure rate of 80%. Other antischistosomal drugs include metrifonate for S. haematobium, oxamniquine for S. mansoni and

    Full Text Available Abstract Huntington disease (HD is a rare neurodegenerative disorder of the central nervous system characterized by unwanted choreatic movements, behavioral and psychiatric disturbances and dementia. Prevalence in the Caucasian population is estimated at 1/10,000-1/20,000. Mean age at onset of symptoms is 30-50 years. In some cases symptoms start before the age of 20 years with behavior disturbances and learning difficulties at school (Juvenile Huntington's disease; JHD. The classic sign is chorea that gradually spreads to all muscles. All psychomotor processes become severely retarded. Patients experience psychiatric symptoms and cognitive decline. HD is an autosomal dominant inherited disease caused by an elongated CAG repeat (36 repeats or more on the short arm of chromosome 4p16.3 in the Huntingtine gene. The longer the CAG repeat, the earlier the onset of disease. In cases of JHD the repeat often exceeds 55. Diagnosis is based on clinical symptoms and signs in an individual with a parent with proven HD, and is confirmed by DNA determination. Pre-manifest diagnosis should only be performed by multidisciplinary teams in healthy at-risk adult individuals who want to know whether they carry the mutation or not. Differential diagnoses include other causes of chorea including general internal disorders or iatrogenic disorders. Phenocopies (clinically diagnosed cases of HD without the genetic mutation are observed. Prenatal diagnosis is possible by chorionic villus sampling or amniocentesis. Preimplantation diagnosis with in vitro fertilization is offered in several countries. There is no cure. Management should be multidisciplinary and is based on treating symptoms with a view to improving quality of life. Chorea is treated with dopamine receptor blocking or depleting agents. Medication and non-medical care for depression and aggressive behavior may be required. The progression of the disease leads to a complete dependency in daily life, which

    Diarrhea is a serious problem affecting 3-5 billion people per year around the world, especially children of below 5 years. 70% of the world population uses traditional and indigenous medicine for their primary health care. The facts of these indigenous remedies are passed verbally and sometimes as documents. Since ancient time, Ayurveda is the main system of healing in South East Asian countries. Indian literature from ayurvedic texts and other books claim the potency of several plants in the treatment of diarrhea. As the global prospective of ayurvedic medicine is increasing, interest regarding the scientific basis of their action is parallely increasing. Researchers are doing experiments to establish the relation between the claimed action and observed pharmacological activities. In the present article, an attempt was made to compile the scientific basis of medicinal plants used to cure diarrhea in Ayurveda. Literature was collected via electronic search (PubMed, ScienceDirect, Medline, and Google Scholar) from published articles that reports antidiarrheal activity of plants that were mentioned in Ayurveda classics. A total of 109 plant species belonging to 58 families were reported for their antidiarrheal activity. Several Indian medicinal plants have demonstrated promising antidiarrheal effects, but the studies on the antidiarrheal potentials of these plants are not taken beyond proof of concept stage. It is hoped that the article would stimulate future clinical studies because of the paucity of knowledge in this area. PMID:27366356

    2014-02-27

    "Bath salts" is one street name for a family of synthetic cathinones that display pharmacological effects resembling cocaine and commonly abused amphetamines. Despite extensive legislation aimed at the criminalization of bath salts, several designer cathinones are gaining a foothold in the illicit drug scene; for example, in the United Kingdom, mephedrone (4-methylmethcathinone, MEPH) is highly popular among drug abusers whereas, in the United States, MDPV (methylenedioxypyrovalerone) and methylone are highly prevalent. To date, knowledge about the hazards of designer cathinones is based mostly on hospital reports and anecdotal evidence derived from online surveys. Despite the paucity of preclinical studies directed toward designer cathinones, a number of invaluable findings arising from those studies are enabling scientists to develop their neuropharmacological profiles. Despite their commonalities in chemical structures, synthetic cathinones possess distinct neuropharmacological profiles and produce different behavioral effects, including unique effects on locomotor activity, learning, anxiety, thermoregulation, and abuse liability. The present review will discuss the behavioral effects of MEPH, MDPV, and methylone and compare those effects to established psychostimulant drugs. The rise in the use of designer cathinones in the United States and abroad justifies further investigations into these compounds, both for a greater understanding of the danger that "bath salts" pose to the public, and to provide insight into replacement cathinones as they emerge onto the market.

  18. Reducing medication errors and increasing patient safety: case studies in clinical pharmacology.

    2003-07-01

    Today, reducing medication errors and improving patient safety have become common topics of discussion for the president of the United States, federal and state legislators, the insurance industry, pharmaceutical companies, health care professionals, and patients. But this is not news to clinical pharmacologists. Improving the judicious use of medications and minimizing adverse drug reactions have always been key areas of research and study for those working in clinical pharmacology. However, added to the older terms of adverse drug reactions and rational therapeutics, the now politically correct expression of medication error has emerged. Focusing on the word error has drawn attention to "prevention" and what can be done to minimize mistakes and improve patient safety. Webster's New Collegiate Dictionary has several definitions of error, but the one that seems to be most appropriate in the context of medication errors is "an act that through ingnorance, deficiency, or accident departs from or fails to achieve what should be done." What should be done is generally known as "the five rights": the right drug, right dose, right route, right time, and right patient. One can make an error of omission (failure to act correctly) or an error of commission (acted incorrectly). This article now summarizes what is currently known about medication errors and translates the information into case studies illustrating common scenarios leading to medication errors. Each case is analyzed to provide insight into how the medication error could have been prevented. "System errors" are described, and the application of failure mode effect analysis (FMEA) is presented to determine the part of the "safety net" that failed. Examples of reengineering the system to make it more "error proof" are presented. An error can be prevented. However, the practice of medicine, pharmacy, and nursing in the hospital setting is very complicated, and so many steps occur from "pen to patient" that there

    Full Text Available Folk uses and scientific investigations have highlighted the importance of Casearia sylvestris extracts and their relevant bioactive potential. The aim of this work was to review the pharmacological properties of C. sylvestris, emphasizing its anti-ulcer, anti-inflammatory, anti-ophidian and antitumor potentialities. Ethanolic extracts and essential oil of their leaves have antiulcerogenic activity and reduce gastric volume without altering the stomach pH, which corroborates their consumption on gastrointestinal disorders. Leaf water extracts show phospholipase A2 inhibitory activity that prevents damage effects on the muscular tissue after toxin inoculation. This antiphospholipasic action is probably related to the use as an anti-inflammatory, proposing a pharmacological blockage similar to that obtained with non-steroidal anti-inflammatory drugs on arachidonic acid and cyclooxygenase pathways. Bioguided-assay fractionations lead to the identification of secondary metabolites, especially the clerodane diterpenes casearins (A-X and casearvestrins (A-C, compounds with a remarkable cytotoxic and antitumor action. Therefore, the C. sylvestris shrub holds a known worldwide pharmacological arsenal by its extensive folk utilization, exciting searches for new molecules and a better comprehension about biological properties.Usos populares e pesquisas científicas têm destacado a importância dos extratos da planta Casearia sylvestris e seu grande potencial bioativo. Neste trabalho, objetiva-se revisar as propriedades farmacológicas de C. sylvestris, enfatizando sua potencialidade antiulcerogênica, antiinflamatória, antiofídica e antitumoral. O extrato etanólico e o óleo essencial das folhas possuem atividade antiulcerogênica promissora, diminuindo o volume gástrico sem alterar o pH estomacal, corroborando sua aplicação contra dores gastrointestinais. Já os extratos aquosos das folhas têm atividade inibitória contra fosfolipase A2 presente

    The highly conserved abundant nuclear protein poly(ADP-ribose)polymerase1 (PARP1) functions at the center of cellular stress response and is mainly implied in DNA damage repair mechanism. Apart from its involvement in DNA damage repair, it does sway multiple vital cellular processes such as cell death pathways, cell aging, insulator function, chromatin modification, transcription and mitotic apparatus function. Since brain is the principal organ vulnerable to oxidative stress and inflammatory responses, upon stress encounters robust DNA damage can occur and intense PARP1 activation may result that will lead to various CNS diseases. In the context of soaring interest towards PARP1 as a therapeutic target for newer pharmacological interventions, here in the present review, we are attempting to give a silhouette of the role of PARP1 in the neurological diseases and the potential of its inhibitors to enter clinical translation, along with its structural and functional aspects.

    Multiple-choice questions are a gold-standard tool in medical school for assessment of knowledge and are the mainstay of licensing examinations. However, multiple-choice questions items can be criticized for lacking the ability to test higher-order learning or integrative thinking across multiple disciplines. Our objective was to develop a novel assessment that would address understanding of pathophysiology and pharmacology, evaluate learning at the levels of application, evaluation and synthesis, and allow students to demonstrate clinical reasoning. The rubric assesses student writeups of clinical case problems. The method is based on the physician's traditional postencounter Subjective, Objective, Assessment and Plan note. Students were required to correctly identify subjective and objective findings in authentic clinical case problems, to ascribe pathophysiological as well as pharmacological mechanisms to these findings, and to justify a list of differential diagnoses. A utility analysis was undertaken to evaluate the new assessment tool by appraising its reliability, validity, feasibility, cost effectiveness, acceptability, and educational impact using a mixed-method approach. The Subjective, Objective, Assessment and Plan assessment tool scored highly in terms of validity and educational impact and had acceptable levels of statistical reliability but was limited in terms of acceptance, feasibility, and cost effectiveness due to high time demands on expert graders and workload concerns from students. We conclude by making suggestions for improving the tool and recommend deployment of the instrument for low-stakes summative assessment or formative assessment. PMID:27445277

    OBJECTIVE To promote the clinical awareness of cross allergy and prevent the occurrence of medical errors. METHODS Prescribing information on cross allergy in "Contraindications" was derived from a software. Records of drug counseling, cases of medical errors and near misses in an online reporting system were analyzed. Data mining was performed. Clinical pharmacological interventions were conducted and the effects were evaluated. RESULTS Besides 27 kinds of drugs within pharmacologically similar class involving cross allergy, there were seven kinds of drugs with complete different pharmacological effects. Similarity in chemical structures was the main case of cross allergy. Excipients were related with cross allergy. Prescribing information in some drugs had unscientific descriptions on cross allergy associated contraindications, lacking clinical value in guiding safe use of medication. There were difference in descriptions on cross allergy in some drugs within pharmacologically similar clas, and some domestic and imported products. The problem of cross allergy of drugs involving different pharmacological effects was dangerous and not easy to be detected. After pharmacological interventions, awareness was greatly increased and the occurrence rate of medical errors and similar mistake decreased by 97%. CONCLISION Severe potential safety hazard might exist if more attentions are not paid to cross allergy aspect. The comprehensive pharmacological interventions are very effective. Applications of information technology and data maintenance are pivotal for continuous quality improvement in cross allergy aspect.%目的 促进临床医护人员对药物交叉过敏的意识,防范用药失误发生.方法 对药物说明书禁忌症中有关交叉过敏的描述进行信息分析和数据挖掘.对药物咨询、用药失误和近似错误在线呈报系统记录进行分析.实施临床药学综合性干预措施,并评估干预效果.结果 除药理作用相似的27

    Studying the effect of drugs on humans, clinical pharmacologists play an essential role in many academic medical and research teams, within the pharmaceutical industry and as members of government regulatory entities. Clinical pharmacology fellowship training programs should be multidisciplinary and adaptable, and should combine didactics, applied learning, independent study, and one-on-one instruction. This article describes a recently developed 2 year clinical pharmacology fellowship program - one of only nine accredited by the American Board of Clinical Pharmacology - that is an integrative, multi faceted, adaptable method for training physicians, pharmacists, and scientists for leadership roles in the pharmaceutical industry, in academia, or with regulatory or accreditation agencies. The purpose of this article is to provide information for academic clinicians and researchers interested in designing a similar program, for professionals in the field of clinical pharmacology who are already affiliated with a fellowship program and may benefit from supplemental information, and for clinical researchers interested in clinical pharmacology who may not be aware that such training opportunities exist. This article provides the details of a recently accredited program, including design, implementation, accreditation, trainee success, and future directions. PMID:25018660

    Full Text Available Ferula communis L., subsp. communis, namely giant fennel, has extensively been used in traditional medicine for a wide range of ailments. Fresh plant materials, crude extracts and isolated components of F. communis showed a wide spectrum of in vitro and in vivo pharmacological properties including antidiabetic, antimicrobial, antiproliferative, and cytotoxic activities. The present paper, reviews the traditional uses, botany, phytochemistry, pharmacology and toxicology of F. communis in order to reveal its therapeutic potential and future research opportunities. A bibliographic literature search was conducted in different scientific databases and search engines including Scopus, Cochrane Library, Embase, Google Scholar, Pubmed, SciFinder, and Web of science. Phytochemical studies have led to the isolation of different compounds such as sesquiterpenes from F. communis. This plant has two different chemotypes, the poisonous and non-poisonous chemotypes. Each chemotype is endowed with various constituents and different activities. The poisonous chemotype exhibits anticoagulant and cytotoxic activities with sesquiterpene coumarins as major constituents, while the non-poisonous one exhibits estrogenic and cytotoxic effects with daucane sesquiterpene esters as the main compounds. In addition, although various pharmacological properties have been reported for F. communis, anti-microbial activities of the plant have been investigated in most studies. Studies revealed that F. communis exhibits different biological activities, and contains various bioactive compounds. Although, antibacterial and cytotoxic activities are the two main pharmacological effects of this plant, further studies should focus on the mechanisms underlying these actions, as well as on those biological activities that have been reported traditionally.

    Attention-deficit/hyperactivity disorder (ADHD) is a common psychological diagnosis in children. This disorder impacts children and adolescents in all areas of life, including academic performance, extracurricular activities, and social interactions. ADHD can continue into adulthood where unemployment and substance abuse has been described. Although behavioral therapy is recommended for all patients with ADHD, medication management typically is initiated soon after diagnosis. Psychostimulants remain the primary medication of choice. This review focuses on the clinical use of psychostimulant medication in children and adolescents. The pharmacodynamic and pharmacokinetic differences between the newest long-acting formulations as well as commonly encountered adverse drug reactions, with suggested management strategies, will be highlighted. Non-stimulant therapy with atomoxetine or alpha2-adrenergic agonists is also reviewed. These agents may be warranted for patients who cannot tolerate psychostimulant therapy or have a comorbid condition. Finally, the 8-year multimodal treatment study results are also discussed.

Only Finnish women currently have access to all three E2-based formulations. E2/NOMAC is currently approved only in Europe, while E2V/DNG is approved globally. To assist clinicians counseling women considering use of one of these formulations, we conducted a review of the published information about the current E2-containing oral contraceptives. A literature search was conducted using the Ovid interface and a combination of free search terms relevant to estradiol and oral contraception to identify suitable articles for inclusion in this review. The available data show that E2V/DNG, E2/NOMAC, and E2V/CPA are all effective oral contraceptives. While direct comparisons are lacking, indirect evidence suggests that E2V/DNG and E2/NOMAC may have better bleeding profiles than E2V/CPA. E2V/DNG is also approved for the treatment of heavy menstrual bleeding. Both E2V/DNG and E2/NOMAC have minimal influence on hemostatic, lipid, and carbohydrate metabolism parameters, or induce less change in these parameters relative to ethinylestradiol-based oral contraceptives. However, the predictive value of these surrogate parameters is a matter of debate, and whether these differences can be translated into meaningful clinical outcomes needs to be established in large-scale, post-marketing, prospective, Phase IV cohort

    Full Text Available Javier Ena, Concepción Amador, Conxa Benito, Francisco PasquauHIV Unit, Hospital Marina Baixa, Villajoyosa, SpainAbstract: We reviewed the current information available on nevirapine immediate- and extended-release formulations and its role in single-dose and combination antiretroviral therapy. Nevirapine was approved in 1996 and was the first non-nucleoside reverse-transcriptase inhibitor available for the treatment of HIV-1 infection. Nevirapine has demonstrated good efficacy and a well-characterized safety profile. A major drawback is the low genetic barrier, allowing the emergence of resistance in the presence of single mutations in the reverse-transcriptase gene. This shortcoming is particularly relevant when nevirapine is administered in a single dose to prevent mother-to-child transmission of HIV-1 infection, compromising the efficacy of future non-nucleoside reverse transcriptase–inhibitor regimens. Studies published recently have probed the noninferiority of nevirapine compared to ritonavir-boosted atazanavir with both tenofovir disoproxil fumarate and emtricitabine in antiretroviral treatment–naïve patients. In 2011, a new formulation of nevirapine (nevirapine extended release that allowed once-daily dosing was approved by the Food and Drug Administration and by the European Medicines Agency. VERxVe, a study comparing nevirapine extended release with nevirapine immediate release in antiretroviral treatment–naïve patients, and TRANxITION, a study carried out in antiretroviral treatment–experienced patients who switched therapy from nevirapine immediate release to nevirapine extended release, provided data on the noninferiority of the new formulation of nevirapine compared with nevirapine immediate release in terms of efficacy and safety. Nevirapine extended release will further increase the durability and persistence of nevirapine-containing antiretroviral therapy, allowing once-daily dosing regimens.Keywords: nevirapine

It commonly affects the deep leg veins (such as the calf veins, femoral vein, or popliteal vein or the deep veins of the pelvis. It is a potentially dangerous condition that can lead to preventable morbidity and mortality.Aim: To present an update on the causes and management of DVT.Methods: A review of publications obtained from Medline search, medical libraries, and Google.Results: DVT affects 0.1% of persons per year. It is predominantly a disease of the elderly and has a slight male preponderance. The approach to making a diagnosis currently involves an algorithm combining pretest probability, D-dimer testing, and compression ultrasonography. This will guide further investigations if necessary. Prophylaxis is both mechanical and pharmacological. The goals of treatment are to prevent extension of thrombi, pulmonary embolism, recurrence of thrombi, and the development of complications such as pulmonary hypertension and post-thrombotic syndrome.Conclusion: DVT is a potentially dangerous condition with a myriad of risk factors. Prophylaxis is very important and can be mechanical and pharmacological. The mainstay of treatment is anticoagulant therapy. Low-molecular-weight heparin, unfractionated heparin, and vitamin K antagonists have been the treatment of choice. Currently anticoagulants specifically targeting components of the common pathway have been recommended for prophylaxis. These include fondaparinux, a selective indirect factor Xa inhibitor and the new oral selective direct thrombin inhibitors (dabigatran and selective

    Full Text Available Hyperglycemia that does not satisfy the diagnostic criteria for diabetes mellitus (DM is generally called prediabetes (preDM. The global prevalence of preDM has been increasing progressively in the past few decades, and it has been established that preDM status is a strong risk factor for DM and cardiovascular disease. Currently, preDM status is classified into two subtypes: impaired fasting glucose and impaired glucose tolerance. Currently, preDM is not regarded as an independent clinical entity, but only as a risk factor for others. In this article, we review various clinical aspects of preDM in terms of the working definition, changes in criteria over the years, epidemiology, and pathophysiological characteristics, and its clinical significance in current medicine.

  1. FDG PET in non-pharmacological therapy in Alzheimer's disease; cerebral metabolic increase correlates with clinical improvement after cognitive therapy

    International Nuclear Information System (INIS)

    In management of AD, pharmacological treatment alone using acetylcholinesterase inhibitor (AChEI) is general consensus, and provides beneficial effect to prolong their progression. Combined non-pharmacological therapy, especially cognitive therapy is recently having attention with expectation of improvement in cognitive ability. This study examined the effect of combined cognitive therapy in AD patients who were maintaining AChEI using FDG PET. Four patients (689 yrs) who diagnosed as probable Alzheimer's disease based on the NINCDS-ADRDA criteria participated in this study. 12-week cognitive therapy comprised seven fields to enhance orientation, memory, recall, visuo-motor organization, categorization and behavior modification/sequencing. They received 45-minute sessions twice per week with maintaining their previous medication. Clinical improvement was assessed by comprehensive neuropsychological tests. Two FDG PET studies were performed before cognitive therapy and in the middle of the therapy, and compared to evaluate the effect of cognitive therapy to cerebral metabolism. Two of 4 patients whose initial cognitive impairment was milder had clinical improvement after 12 weeks, the rest who were more severely impaired failed to have clinical improvement. Regional cerebral hypometabolism on initial PET was correlated with their functional status. Follow up PET of two responders demonstrated the increases in regional metabolism in the temporal and/or frontal cortex, which was associated their functional improvement. Cerebral metabolism in poor responders were minimally increased or no changed. This preliminary data suggests that cognitive therapy is potentially useful to stabilize or improve cognitive and functional performance in AD patients with relatively mild cognitive dysfunction. And FDG PET could demonstrate possible candidates for cognitive therapy and the effect of the therapy

    Full Text Available Kashif M Munir,1 Stephen N Davis2 1Division of Endocrinology, Diabetes, and Nutrition, Center for Diabetes and Endocrinology, 2Department of Medicine, University of Maryland School of Medicine, Baltimore, MD, USA Abstract: With rates of obesity and diabetes rising across the world, effective therapies to treat hyperglycemia and its associated comorbidities continue to be in demand. Empagliflozin is a highly selective sodium glucose transporter-2 inhibitor that improves serum glucose levels by inducing glucosuria. Taken orally, it is rapidly absorbed with linear pharmacokinetics consistent in Asian and Caucasian populations. Empagliflozin treatment demonstrates consistent reductions in hemoglobin A1c, fasting plasma glucose, body weight, and blood pressure in individuals with type 2 diabetes. Improvements in glycemic control and metabolic end points are evident with empagliflozin monotherapy, as add-on to oral hypoglycemics or add-on to insulin. The nonglycemic effects of empagliflozin with consistent improvements in blood pressure, body weight, and waist circumference provide additional rationale for use in patients with type 2 diabetes. Moreover, treatment with empagliflozin has recently shown significant reductions in both microvascular and macrovascular complications of diabetes.

    Davis, Robert E; Correll, Christoph U

    2016-06-01

    ITI-007 is an investigational drug being developed for schizophrenia and other neuropsychiatric/neurodegenerative diseases. ITI-007 has a unique pharmacological profile, combining potent 5-HT2a receptor antagonism with cell-type-specific dopamine and glutamate receptor modulation, plus serotonin reuptake inhibition. At dopamine-D2 receptors, ITI-007 acts as a post-synaptic antagonist and pre-synaptic partial agonist. Additionally, ITI-007 stimulates phosphorylation of glutamatergic NMDA-NR2B receptors, downstream of dopamine-D1 receptor intracellular signaling. Based on a large, placebo and risperidone controlled, Phase-II trial, ITI-007 60 mg was shown to be effective in reducing symptoms in patients with acutely exacerbated schizophrenia. The antipsychotic efficacy of ITI-007 60 mg in this patient population was confirmed in a recently completed Phase III study. ITI-007 was associated with minimal safety risk compared to risperidone (Phase II study) or placebo (both studies) for neuromotor disturbances, prolactin changes, weight gain and metabolic abnormalities. A second 6-week, placebo and risperidone-controlled Phase-III trial in acutely exacerbated schizophrenia is ongoing. PMID:27042868

    Alcohol use disorders (AUD) cause significant morbidity and mortality worldwide, but pharmacological treatments for them are underused, despite evidence of efficacy. Acamprosate, naltrexone, nalmefene and disulfiram are all approved in one or more region for the treatment of AUD. Baclofen currently has a temporary indication in France. Safety considerations for using psychopharmacological treatments in this patient group include the impact of concurrent alcohol consumption at high levels; multiple physical comorbidities that may interfere with pharmacological effects, distribution and metabolism; and concomitant medication for the treatment of comorbid physical and psychiatric conditions. The five drugs, including an extended-release injectable suspension of naltrexone, have different safety profiles that need to be balanced with the treatment objective (initiation or continuation of abstinence, or reduction of drinking), individual patient preferences and comorbid conditions. Appropriate treatment will be based on the unique risk-benefit profile in each case. PMID:27023898

    2016-01-01

    Asthma in the elderly is a disease with emerging concern. Despite some recent advances in our understanding of epidemiology and pathophysiology, there is a considerable lack of clinical evidence specific to elderly patients. Currently available high quality clinical evidence has been mostly obtained from younger adults, but rarely from elderly patients. Under-representation of elderly patients in previous randomized trials may have been due to being, old age, or having comorbidities. Thus, a question may be raised whether current clinical evidence could be well generalized into elderly patients. Further clinical trials should address clinical issues raised in elderly population. In this review, we aimed to overview the efficacy and safety of pharmacological management, and also to summarize the literature relevant to elderly asthma. PMID:26844215

    2012-11-01

    Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) are retroviruses with global impact on the health of domestic cats. The two viruses differ in their potential to cause disease. FeLV is more pathogenic, and was long considered to be responsible for more clinical syndromes than any other agent in cats. FeLV can cause tumors (mainly lymphoma), bone marrow suppression syndromes (mainly anemia), and lead to secondary infectious diseases caused by suppressive effects of the virus on bone marrow and the immune system. Today, FeLV is less commonly diagnosed than in the previous 20 years; prevalence has been decreasing in most countries. However, FeLV importance may be underestimated as it has been shown that regressively infected cats (that are negative in routinely used FeLV tests) also can develop clinical signs. FIV can cause an acquired immunodeficiency syndrome that increases the risk of opportunistic infections, neurological diseases, and tumors. In most naturally infected cats, however, FIV itself does not cause severe clinical signs, and FIV-infected cats may live many years without any health problems. This article provides a review of clinical syndromes in progressively and regressively FeLV-infected cats as well as in FIV-infected cats. PMID:23202500

    Rationale Limited pharmacological data are available to guide methadone treatment during pregnancy and postpartum. Objectives Study goals were to: 1) Characterize changes in methadone dose across childbearing, 2) Determine enantiomer-specific methadone withdrawal kinetics from steady-state during late pregnancy, 3) Assess enantiomer-specific changes in methadone level/dose (L/D) ratios across childbearing, and 4) Explore relationships between CYP2B6, CYP2C19 and CYP3A4 single nucleotide polymorphisms and maternal dose, plasma concentration and L/D. Methods Methadone dose changes and timed plasma samples were obtained for women on methadone (n=25) followed prospectively from third trimester of pregnancy to three months postpartum. Results Participants were primarily white, Medicaid insured and multiparous. All women increased their dose from first to end of second trimester (mean peak increase=23 mg/day); 71% of women increased from second trimester to delivery (mean peak increase=19 mg/day). Half took a higher dose 3 months postpartum than at delivery despite significantly larger clearance during late pregnancy. Third trimester enantiomer-specific methadone half-lives (range R-methadone 14.7-24.9 hours; S-methadone 8.02-18.9 hours) were about half of those reported in non-pregnant populations. In 3 women with weekly 24-hour methadone levels after delivery, L/D increased within 1-2 weeks after delivery. Women with the CYP2B6 Q172 variant GT genotype have consistently higher L/D values for S-methadone across both pregnancy and postpartum. Conclusions Most women require increases in methadone dose across pregnancy. Given the shorter half-life and larger clearances during pregnancy, many pregnant women may benefit from split methadone dosing. L/D increases quickly after delivery and doses should be lowered rapidly after delivery. PMID:22926004

    BACKGROUND: Blinding is a pivotal method to avoid bias in randomised clinical trials. In blinded drug trials, experimental and control interventions are often designed to be matched, i.e. to appear indistinguishable. It is unknown how often matching procedures are inadequate, so we decided to sys...

    The aim of this systematic review was to synthesize the best available evidence informing the effectiveness of non-pharmacological interventions for managing cancer-related fatigue in men treated for prostate cancer. This review considered experimental studies that included men with prostate cancer (regardless of staging, previous treatment or comorbidities), aged 18 years and over who were undergoing any treatment, or had completed any treatment for prostate cancer within the previous 12 months. Three interventions were identified for the management of cancer-related fatigue in men with prostate cancer. Evidence from five studies including 447 participants demonstrates the effectiveness of physical activity, both aerobic and resistance exercise, and from three studies including 153 participants suggesting the benefits of psychosocial interventions including education and cognitive behavioural therapy. Health professionals require knowledge of a range of effective interventions aimed at reducing cancer-related fatigue in men with prostate cancer and should incorporate those interventions into their patient management. Although physical activity appears to show the greatest benefit, other non-pharmacological interventions such as education and cognitive behavioural therapy have demonstrated benefit and should also be considered as a strategy in treating this debilitating side effect of cancer and its treatment.

    Inflammatory demyelinating diseases comprise a spectrum of disorders affecting the myelin of the central and peripheral nervous system. These diseases can usually be differentiated on the basis of clinical, radiological, laboratory and pathological findings. Recent studies have contributed to current awareness that inflammatory demyelinating diseases are not restricted to the adult age group, but are more common in pediatric age than previously believed. Some of pediatric inflammatory demyeli...

    The biologic role of thyroid-stimulating hormone (TSH; thyrotropin) as an activator (agonist) of the TSH receptor (TSHR) in the hypothalamic–pituitary–thyroid axis is well known and activation of TSHR by recombinant human TSH is used clinically in patients with thyroid cancer. TSHR ligands other than TSH could be used to probe TSHR biology in thyroidal and extrathyroidal tissues, and potentially be employed in patients. A number of different TSHR ligands have been reported, including TSH anal...

    Clinical trials have consistently shown the benefits of beta-blocker treatment in patients with chronic heart failure (HF). As a result, bisoprolol, carvedilol, and metoprolol succinate are now indicated for the treatment of all patients with chronic HF who do not have major contraindications. Bisoprolol is the first beta-blocker shown to improve survival in an outcome trial. In the Cardiac Insufficiency Bisoprolol Study II (CIBIS-II), all-cause mortality and sudden death were reduced in pati...

  9. Clinical Management of Priapism: A Review.

    Shigehara, Kazuyoshi; Namiki, Mikio

    2016-04-01

    Priapism is defined as a persistent and painful erection lasting longer than four hours without sexual stimulation. Based on episode history and pathophysiology, priapism is classified into three subtypes: ischemic (low-flow), non-ischemic (high-flow), and stuttering priapism. Ischemic priapism is characterized by a persistent, painful erection with remarkable rigidity of the corpora cavernosa caused by a disorder of venous blood outflow from this tissue mass, and is similar to penile compartment syndrome. Stuttering priapism is characterized by a self-limited, recurrent, and intermittent erection, frequently occurring in patients with sickle cell disease. Non-ischemic priapism is characterized by a painless, persistent nonsexual erection that is not fully rigid and is caused by excess arterial blood flow into the corpora cavernosa. Because ischemic and non-ischemic priapism differ based on emergency status and treatment options, appropriate discrimination of each type of priapism is required to initiate adequate clinical management. The goal of management of priapism is to achieve detumescence of the persistent penile erection and to preserve erectile function after resolution of the priapism. To achieve successful management, urologists should address this emergency clinical condition. In the present article, we review the diagnosis and clinical management of the three types of priapism.

    Full Text Available In this paper we discuss the consensus view on the use of qualifying biomarkers in drug safety, raised within the frame of the XXIV meeting of the Spanish Society of Clinical Pharmacology held in Málaga (Spain in October, 2011.The widespread use of biomarkers as surrogate endpoints is a goal that scientists have long been pursuing. Thirty years ago, when molecular pharmacogenomics evolved, we anticipated that these genetic biomarkers would soon obviate the routine use of drug therapies in a way that patients should adapt to the therapy rather than the opposite. This expected revolution in routine clinical practice never took place as quickly nor with the intensity as initially expected.The concerted action of operating multicenter networks holds great promise for future studies to identify biomarkers related to drug toxicity and to provide better insight into the underlying pathogenesis. Today some pharmacogenomic advances are already widely accepted, but pharmacogenomics still needs further development to elaborate more precise algorithms and many barriers to implementing individualized medicine exist. We briefly discuss our view about these barriers and we provide suggestions and areas of focus to advance in the field.

    Medicinal plants have historically proven their value as a source of molecules with therapeutic potential, and nowadays still represent an important pool for the identification of novel drug leads. In the past decades, pharmaceutical industry focused mainly on libraries of synthetic compounds as drug discovery source. They are comparably easy to produce and resupply, and demonstrate good compatibility with established high throughput screening (HTS) platforms. However, at the same time there has been a declining trend in the number of new drugs reaching the market, raising renewed scientific interest in drug discovery from natural sources, despite of its known challenges. In this survey, a brief outline of historical development is provided together with a comprehensive overview of used approaches and recent developments relevant to plant-derived natural product drug discovery. Associated challenges and major strengths of natural product-based drug discovery are critically discussed. A snapshot of the advanced plant-derived natural products that are currently in actively recruiting clinical trials is also presented. Importantly, the transition of a natural compound from a “screening hit” through a “drug lead” to a “marketed drug” is associated with increasingly challenging demands for compound amount, which often cannot be met by re-isolation from the respective plant sources. In this regard, existing alternatives for resupply are also discussed, including different biotechnology approaches and total organic synthesis. While the intrinsic complexity of natural product-based drug discovery necessitates highly integrated interdisciplinary approaches, the reviewed scientific developments, recent technological advances, and research trends clearly indicate that natural products will be among the most important sources of new drugs also in the future.

    Coinciding with the continually increasing population of immunocompromised patients worldwide, the incidence of invasive fungal infections has grown over the past 4 decades. Unfortunately, infections caused by both yeasts such as Candida and molds such as Aspergillus or Mucorales remain associated with unacceptably high morbidity and mortality. In addition, the available antifungals with proven efficacy in the treatment of these infections remain severely limited. Although previously available second-generation triazole antifungals have significantly expanded the spectrum of the triazole antifungal class, these agents are laden with shortcomings in their safety profiles as well as formulation and pharmacokinetic challenges. Isavuconazole, administered as the prodrug isavuconazonium, is the latest second-generation triazole antifungal to receive U.S. Food and Drug Administration approval. Approved for the treatment of both invasive aspergillosis and invasive mucormycosis, and currently under investigation for the treatment of candidemia and invasive candidiasis, isavuconazole may have therapeutic advantages over its predecessors. With clinically relevant antifungal potency against a broad range of yeasts, dimorphic fungi, and molds, isavuconazole has a spectrum of activity reminiscent of the polyene amphotericin B. Moreover, clinical experience thus far has revealed isavuconazole to be associated with fewer toxicities than voriconazole, even when administered without therapeutic drug monitoring. These characteristics, in an agent available in both a highly bioavailable oral and a β-cyclodextrin-free intravenous formulation, will likely make isavuconazole a welcome addition to the triazole class of antifungals.

    We have attempted to review developmental intervention for pediatricians in a way that is of clinical relevance to primary care pediatricians. In so doing, we chose not to evaluate certain topics such as therapeutic intervention for handicapped children or center-based educational programs because these have been adequately addressed elsewhere. It is clear that pediatricians have a unique and important role to play in developmental intervention for the following reasons: pediatricians have easy and routinely accepted access to infants and families in the prenatal, perinatal, and preschool periods: pediatricians possess a socially accepted role of authority; and pediatricians can integrate understanding of the child's health and developmental status within the context of the family and social environment to make clinical interpretation regarding the child's developmental status and prognosis. Pediatricians are thus in the best position to convince parents of their impact on their child's development. The following general roles have been identified for pediatricians. First, pediatricians should be aware of the child's biologic status and family environmental situation and the relative degree of risk for developmental problems. This clinical awareness, in combination with the use of appropriate screening instruments of the child's development and family environment, will allow clinical judgment regarding the frequency and type of child health supervision, the need for further diagnostic evaluation, and the need for referral to intervention programs and other resources. Second, the pediatrician should develop an approach for developmental intervention for all children, whatever their degree of biological risk. This review of medical, educational, and psychological literature demonstrate the following recurring important themes as goals for primary intervention: Improve parental understanding of normal child development and developmental expectations.

It is an antagonist of the 5-HT3 and 5-HT7 receptors, a partial agonist of 5-HT1B, and an agonist of 5-HT1A. Its combined action on SERT and four subtypes of serotoninergic receptors increases the extracellular concentration of serotonin, dopamine, and noradrenaline. Twelve ­clinical trials have been carried out, nine of which had positive results versus placebo. When active comparators were included in the study design, no significant differences were found except in one study in which the efficacy of vortioxetine was superior to the comparator (agomelatine in depression resistant to selective serotonin reuptake inhibitors (SSRI/serotonin–norepinephrine reuptake inhibitors (SNRI treatment. Tolerability studies indicate that the drug does not cause any important problems on blood tests, vital signs, or on electrocardiography. The lack of weight gain and induction of metabolic syndrome and the lack of significant changes in the QTc are especially important. The incidence rate of sexual dysfunction is low and similar to placebo in various trials. Similarly, cognitive function remains intact with vortioxetine.

    Today 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) are the most often prescribed drugs among the therapeutics for hypercholesterolemia. Pitavastatin is a novel statin that has been developed entirely in Japan from the biological screening to clinical studies persuing more efficatious statin than hitherto known. Preclinical studies on drug metabolism revealed that pitavastatin is distributed selectively to the liver, excreted into bile without metabolic modification, and efficiently re-circulates to the liver to show a prolonged plasma half-life. In guinea pigs, pitavastatin enhanced hepatic LDL receptor activity and reduced VLDL secretion in a liver perfusion study, and it lowered plasma total cholesterol (TC) levels at 0.3 mg/kg and triglyceride (TG) levels at 1 mg/kg, respectively, and more. From these results, pitavastatin is assumed to lower LDL cholesterol (LDL-C) by promoting LDL receptor expression and further potentiate the cholesterol-lowering effect and exert TG-lowering effect by reducing VLDL secretion. (14)C-Pitavastatin is metabolized with CYP2C9 to 8-hydroxy derivative, but its Vmax /Km was about 2 micro l/min/mg, about 1/8 to 1/100 in comparison to the reported values of other statins, indicating that pitavastatin is hardly metabolized. Also, other human P450 species were not inhibited by pitavastatin. Therefore, pitavastatin is considered to have little interaction with drugs through P450. In the summarized clinical results with 862 patients, pitavastatin lowered TC and LDL-C by 28% and 40%, respectively. There was no difference in the frequency of side effects and no serious adverse effect was observed for pitavastatin. Pitavastatin possesses superior plasma lipid-improving effects, induces little drug interaction, and is expected to make a good contribution to the medication of hypercholesterolemia. PMID:15118259

    Full Text Available The current treatment of Parkinson’s disease with dopamine-centric approaches such as L-DOPA and dopamine agonists, although very succesfull, is in need of alternative treatment strategies, both in terms of disease modification and symptom management. Various non-dopaminergic treatment approaches did not result in a clear clinical benefit, despite showing a clear effect in preclinical animal models. In addition, polypharmacy is common, sometimes leading to unintended effects on non-motor symptoms such as in cognitive and psychiatric domains. To explore novel targets for symptomatic treatment and possible synergistic pharmacodynamic effects between different drugs, we developed a Quantitative Systems Pharmacology (QSP platform of the closed cortico-striatal-thalamic-cortical basal ganglia loop of the dorsal motor circuit.

    Hyaluronidase is employed therapeutically since many years. The various detectable effects of hyaluronidase are referred to the action of this enzyme. Hyaluronidase depolymerises the mucopolysaccharide hyaluronic acid, a component of the mucoprotein ground substance or tissue cement. Hyaluronidase thereby increases in tissues the membrane permeability, reduces the viscosity and renders the tissues more readily permeable to injected fluids (spreading effect). The effects of hyaluronidase enables this enzyme to be used therapeutically to increase the speed of absorption and to diminish discomfort due to subcutaneous or intramuscular injection of fluid, to promote resorption of excess fluids and extravasated blood in the tissues and to increase the effectiveness of local anaesthesia. Hyaluronidase is widely used in many fields, i.e. in orthopaedia, surgery, ophthalmology, internal medicine, oncology, dermatology, gynaecology, etc. The following paper deals with the therapeutic uses of hyaluronidases and allows a review of the current and up to date status of the literature.

    Genus Alpinia consists of over 250 species, which are widely distributed in south and southeast Asia. Many plants of genus Alpinia have been used for thousands of years to treat digestive system diseases and as anti-inflammatory drugs. Phytochemical research on this genus has led to the isolation of different kinds of diarylheptanoids, terpenes triterpenoids, phenylbutanoids, lignans, and flavonoids. Experimental evidences revealed that both the crude extracts and pure constituents isolated from the genus Alpinia exhibit a wide range of bioactivities such as anti-cancer, anti-oxidant, anti-bacterial, anti-viral, cardiovascular, and digestive system protective effects. Here, we summarize the phytochemistry and pharmacology investigation of the genus Alpinia, which can provide reference for further research and drug development.

    Pain is one of the main complaints of trauma patients in (pre-hospital) emergency medicine. Significant deficiencies in pain management in emergency medicine have been identified. No evidence-based protocols or guidelines have been developed so far, addressing effectiveness and safety issues, taking the specific circumstances of pain management of trauma patients in the chain of emergency care into account. The aim of this systematic review was to identify effective and safe initial pharmacological pain interventions, available in the Netherlands, for trauma patients with acute pain in the chain of emergency care. Up to December 2011, a systematic search strategy was performed with MeSH terms and free text words, using the bibliographic databases CINAHL, PubMed and Embase. Methodological quality of the articles was assessed using standardized evaluation forms. Of a total of 2328 studies, 25 relevant studies were identified. Paracetamol (both orally and intravenously) and intravenous opioids (morphine and fentanyl) proved to be effective. Non-steroidal anti-inflammatory drugs (NSAIDs) showed mixed results and are not recommended for use in pre-hospital ambulance or (helicopter) emergency medical services [(H)EMS]. These results could be used for the development of recommendations on evidence-based pharmacological pain management and an algorithm to support the provision of adequate (pre-hospital) pain management. Future studies should address analgesic effectiveness and safety of various drugs in (pre-hospital) emergency care. Furthermore, potential innovative routes of administration (e.g., intranasal opioids in adults) need further exploration. PMID:23737462

    Full Text Available Craig A Portell, Candice M Wenzell, Anjali S Advani Leukemia Program, Taussig Cancer Institute, Cleveland Clinic, Cleveland, OH, USA Abstract: Acute lymphoblastic leukemia (ALL in adults remains a challenging disease to treat, and novel therapies are needed. Precursor-B ALL comprises 80% of cases, and the CD19 antigen is expressed in nearly all precursor-B ALL patients. Bispecific T-cell-engaging antibodies are novel bioengineered proteins. The bispecific T-cell-engaging antibody blinatumomab engages polyclonal T cells to CD19-expressing B cells. By binding to both CD3 and CD19, blinatumomab physically brings these T cells in close proximity to malignant B cells and potentiates T-cell-induced cytotoxic cell kill. Blinatumomab requires continuous intravenous infusion due to its short half-life, the need for continuous exposure for the drug to exert sufficient efficacy, and lessened toxicity. A phase II trial of B-cell ALL patients with persistent or relapsed minimal residual disease demonstrated an 80% rate of complete molecular remission. Cytokine-release syndrome and central nervous system events, such as seizures and encephalopathy, are reversible toxicities. Promising results in B-cell ALL with minimal residual disease have led to further evaluation of this drug in newly diagnosed and relapsed B-cell ALL.

  5. Escitalopram--translating molecular properties into clinical benefit: reviewing the evidence in major depression.

    LENUS (Irish Health Repository)

    Leonard, Brian

    2010-08-01

    The majority of currently marketed drugs contain a mixture of enantiomers; however, recent evidence suggests that individual enantiomers can have pharmacological properties that differ importantly from enantiomer mixtures. Escitalopram, the S-enantiomer of citalopram, displays markedly different pharmacological activity to the R-enantiomer. This review aims to evaluate whether these differences confer any significant clinical advantage for escitalopram over either citalopram or other frequently used antidepressants. Searches were conducted using PubMed and EMBASE (up to January 2009). Abstracts of the retrieved studies were reviewed independently by both authors for inclusion. Only those studies relating to depression or major depressive disorder were included. The search identified over 250 citations, of which 21 studies and 18 pooled or meta-analyses studies were deemed suitable for inclusion. These studies reveal that escitalopram has some efficacy advantage over citalopram and paroxetine, but no consistent advantage over other selective serotonin reuptake inhibitors. Escitalopram has at least comparable efficacy to available serotonin-norepinephrine reuptake inhibitors, venlafaxine XR and duloxetine, and may offer some tolerability advantages over these agents. This review suggests that the mechanistic advantages of escitalopram over citalopram translate into clinical efficacy advantages. Escitalopram may have a favourable benefit-risk ratio compared with citalopram and possibly with several other antidepressant agents.

    Aerosolized medications are used as airway clearance therapy to treat a variety of airway diseases. These guidelines were developed from a systematic review with the purpose of determining whether the use of these medications to promote airway clearance improves oxygenation and respiratory mechanics, reduces ventilator time and ICU stay, and/or resolves atelectasis/consolidation compared with usual care. Recombinant human dornase alfa should not be used in hospitalized adult and pediatric patients without cystic fibrosis. The routine use of bronchodilators to aid in secretion clearance is not recommended. The routine use of aerosolized N-acetylcysteine to improve airway clearance is not recommended. Aerosolized agents to change mucus biophysical properties or promote airway clearance are not recommended for adult or pediatric patients with neuromuscular disease, respiratory muscle weakness, or impaired cough. Mucolytics are not recommended to treat atelectasis in postoperative adult or pediatric patients, and the routine administration of bronchodilators to postoperative patients is not recommended. There is no high-level evidence related to the use of bronchodilators, mucolytics, mucokinetics, and novel therapy to promote airway clearance in these populations. PMID:26113566

    2010-08-01

    Full Text Available For development to proceed normally, animal eggs must undergo a maturation process that ultimately depends on phosphorylations of key regulatory proteins. To analyze the kinases that mediate these phosphorylations, eggs of marine nemertean worms have been treated with pharmacological modulators of intracellular signaling pathways and subsequently probed with immunoblots employing phospho-specific antibodies. This article both reviews such analyses and compares them with those conducted on mammals, while focusing on how egg maturation in nemerteans is affected by signaling pathways involving cAMP, mitogen-activated protein kinases, Src-family kinases, protein kinase C isotypes, AMP-activated kinase, and the Cdc2 kinase of maturation-promoting factor.

    Full Text Available Between 23%–46% of children with cerebral palsy experience sleep problems. Many of the sensory-motor and cognitive features of cerebral palsy (such as immobility, pain, and seizures act as predisposing factors for sleep problems in this population. This paper presents the background related to the etiology and consequences of sleep problems in children with cerebral palsy. The relationship between pain and sleep is emphasized, as the risk of pain is highly prevalent in children with cerebral palsy. The review concludes with a discussion of the evidence-base for environmental non-pharmacological interventions based on light, temperature, sound and bedding to promote sleep for children with cerebral palsy.

    Full Text Available Philippe Lagacé-Wiens,1,2 Andrew Walkty,1,2 James A Karlowsky1,2 1Clinical Microbiology, Diagnostic Services Manitoba, 2Department of Medical Microbiology and Infectious Diseases, Faculty of Medicine, University of Manitoba, Winnipeg, MB, Canada Abstract: Avibactam (NXL104, AVE1330A is a semi-synthetic, non-β-lactam, β-lactamase inhibitor that is active against Ambler class A, class C, and some class D serine β-lactamases. In this review, we summarize the in vitro data, pharmacology, mechanisms of action and resistance, and clinical trial data relating to the use of this agent combined with ceftazidime for the treatment of Gram-negative bacterial infections. The addition of avibactam to ceftazidime improves its in vitro activity against Enterobacteriaceae and Pseudomonas aeruginosa. Avibactam does not improve the activity of ceftazidime against Acinetobacter spp., Burkholderia spp., or most anaerobic Gram-negative rods. Pharmacodynamic data indicate that ceftazidime–avibactam is bactericidal at concentrations achievable in human serum. Animal studies demonstrate that ceftazidime–avibactam is effective in ceftazidime-resistant Gram-negative septicemia, meningitis, pyelonephritis, and pneumonia. Limited clinical trials published to date have reported that ceftazidime–avibactam is as effective as therapy with a carbapenem in complicated urinary tract infection and complicated intra-abdominal infection (combined with metronidazole including infection caused by cephalosporin-resistant Gram-negative isolates. Safety and tolerability of ceftazidime–avibactam in clinical trials has been excellent, with few serious drug-related adverse events reported. Given the abundant clinical experience with ceftazidime and the significant improvement that avibactam provides in its activity against contemporary β-lactamase-producing Gram-negative pathogens, it is likely this new combination agent will play a role in the empiric treatment of complicated

    Osteoarthritis (OA) is the most common form of arthritis and its current treatment includes non-pharmacological and pharmacological modalities. Spa therapy represents a popular treatment for many rheumatic diseases. The aim of this review was to summarize the currently available information on clinical effects and mechanisms of action of spa therapy in OA of the hand. We conducted a search of the literature to extract articles describing randomized clinical trials (RCTs) in hand OA published in the period 1952-2015. We identified three assessable articles reporting RCTs on spa therapy in hand OA. Data from these clinical trials support a beneficial effect of spa therapy on pain, function and quality of life in hand OA. Spa therapy seems to have a role in the treatment of hand OA. However, additional RCTs are necessary to clarify the mechanisms of action and the effects of the application of thermal treatments.

    Catha edulis (khat) is a plant grown commonly in the horn of Africa. The leaves of khat are chewed by the people for its stimulant action. Its young buds and tender leaves are chewed to attain a state of euphoria and stimulation. Khat is an evergreen shrub, which is cultivated as a bush or small tree. The leaves have an aromatic odor. The taste is astringent and slightly sweet. The plant is seedless and hardy, growing in a variety of climates and soils. Many different compounds are found in khat including alkaloids, terpenoids, flavonoids, sterols, glycosides, tannins, amino acids, vitamins and minerals. The phenylalkylamines and the cathedulins are the major alkaloids which are structurally related to amphetamine. The major effects of khat include those on the gastro-intestinal system and on the nervous system. Constipation, urine retention and acute cardiovascular effects may be regarded as autonomic (peripheral) nervous system effects; increased alertness, dependence, tolerance and psychiatric symptoms as effects on the central nervous system. The main toxic effects include increased blood pressure, tachycardia, insomnia, anorexia, constipation, general malaise, irritability, migraine and impaired sexual potency in men. Databases such as Pubmed, Medline, Hinary, Google search, Cochrane and Embase were systematically searched for literature on the different aspects of khat to summarize chemistry, pharmacology, toxicology of khat (Catha edulis Forsk).

    Full Text Available Background: Internship is the intermediate period between under-graduation and general practice. The dexterity of health professional relies upon prescribing practices. Clinical pharmacology and therapeutics (CPT is a crucial discipline for interns to acquire safe and rational prescription of drugs. Cultivating sound knowledge about CPT during under graduation is, henceforth, mandatory. Aims and objectives: 1.To assess whether the undergraduate CPT teaching and internship training had prepared interns adequately for safe and rational prescription. 2.To assess the awareness and reporting of adverse drug reaction (ADR. Methods: 110 interns were enrolled after obtaining informed written consent. A structured questionnaire was given to them including basic demographic information, undergraduate CPT teaching, experience of ADR and any deficiency in the under-graduate CPT teaching. Results: Response rate was 91 % in which 53 were males and 47 females. 81 considered themselves aware of CPT. 56% & 57% interns were able to prescribe drug safely and rationally respectively. Without supervision, they were confident to prescribe antacids (93%, vitamins and minerals (90%, NSAIDS (85%, antihistamines (82%, antibiotics (75%, antiemetics (62% and antiasthmatics (52%. Only 22% had reported ADR and opined that it could lead to hospitalization (51%, prolonged hospital stay (33%, morbidity (16% and death (21%. According to interns, the topics where more emphasis needed were ADR, dosage calculation, pediatric and emergency medicine and therapeutic drug monitoring during undergraduate CPT teaching. Conclusion: CPT teaching should be improved at undergraduate level for safe and rational prescribing including ADR monitoring, ADR reporting and dosage calculation.

    An increasing number of novel psychoactive substances are currently available and sold as 'legal highs' or 'research chemicals' accompanied by the indication that they are 'not for human consumption'. Among those that have emerged in the last few years, methoxetamine (MXE) owes its wide popularity to its easy access on the Internet and its reputation of being a 'safe' drug. MXE is an arylcyclohexylamine with a chemical structure analogous to ketamine and phencyclidine, and similar noncompetitive glutamate N-methyl D-aspartate receptor antagonist properties. Yet, very recent preclinical data highlighted a stimulatory effect of MXE on dopamine neurotransmission within the mesolimbic pathway. The aim of this review is to provide an updated review of the behavioral and toxicological effects of MXE as well as the latest findings on its pharmacology that might explain sought effects and frequent occurrence of adverse effects. In light of the growing number of intoxications induced by MXE, knowledge of its short-term and long-term effects is urgently needed. However, the hypothetical rapid antidepressant activity of MXE suggested by its chemical analogy with ketamine and supported by recent preclinical findings deserves further investigation.

    Full Text Available The CellScan apparatus is a laser scanning cytometer enabling repetitive fluorescence intensity (FI and polarization (FP measurements in living cells, as a means of monitoring lymphocyte activation. The CellScan may serve as a tool for diagnosis of rheumatoid arthritis (RA and systemic lupus erythematosus (SLE as well as other autoimmune diseases by monitoring FP changes in peripheral blood lymphocytes (PBLs following exposure to autoantigenic stimuli. Changes in FI and FP in atherosclerotic patients' PBLs following exposure to various stimuli have established the role of the immune system in atherosclerotic disease. The CellScan has been evaluated as a diagnostic tool for drug-allergy, based on FP reduction in PBLs following incubation with allergenic drugs. FI and FP changes in cancer cells have been found to be well correlated with the cytotoxic effect of anti-neoplastic drugs. In conclusion, the CellScan has a variety of applications in cell biology, immunology, cancer research and clinical pharmacology.

The aim of this study was therefore to assess how adequately the undergraduate CPT teaching had prepared interns in Nigeria for safe and rational prescribing and retrospectively, to know how they wanted the undergraduate curriculum to be modified so as to improve appropriate prescribing. The effect of internship training on the prescribing ability of the interns was also sought. Methods A total of 100 interns were randomly selected from the Lagos State University Teaching Hospital (LASUTH, Ikeja; Lagos University Teaching Hospital (LUTH, Idiaraba; General Hospital Lagos (GHL; the EKO Hospital, Ikeja; and Havana Specialist Hospital, Surulere. A structured questionnaire was the instrument of study. The questionnaire sought information about the demographics of the interns, their undergraduate CPT teaching, experience of adverse drug reactions (ADRs and drug interactions since starting work, confidence in drug usage and, in retrospect; any perceived deficiencies in their undergraduate CPT teaching. Results The response rate was 81%. All the respondents graduated from universities in Nigeria. The ability of the interns to prescribe rationally (66, 81.4% and safely (47, 58% was provided by undergraduate CPT teaching. Forty two (51.8% respondents had problems with prescription writing.

    Statins, in addition to their lipid-lowering properties, have anti-inflammatory actions. The aim of this review is to evaluate the effect of pre-injury statin use, and statin treatment following injury. MEDLINE, EMBASE, and CENTRAL databases were searched to January 2012 for randomised and observational studies of statins in trauma patients in general, and in patients who have suffered traumatic brain injury, burns, and fractures. Of 985 identified citations, 7 (4 observational studies and 3 randomised controlled trials (RCTs)) met the inclusion criteria. Two studies (both observational) were concerned with trauma patients in general, two with patients who had suffered traumatic brain injury (one observational, one RCT), two with burns patients (one observational, one RCT), and one with fracture healing (RCT). Two of the RCTs relied on surrogate outcome measures. The observational studies were deemed to be at high risk of confounding, and the RCTs at high risk of bias. Three of the observational studies suggested improvements in a number of clinical outcomes in patients taking statins prior to injury (mortality, infection, and septic shock in burns patients; mortality in trauma patients in general; mortality in brain injured patients) whereas one, also of trauma patients in general, showed no difference in mortality or infection, and an increased risk of multi-organ failure. Two of three RCTs on statin treatment in burns patients and brain injured patients showed improvements in E-selectin levels and cognitive function. The third, of patients with radial fractures, showed no acceleration in fracture union. In conclusion, there is some evidence that pre-injury statin use and post-injury statin treatment may have a beneficial effect in patients who have suffered general trauma, traumatic brain injury, and burns. However, these studies are at high risk of confounding and bias, and should be regarded as 'hypothesisgenerating'. A well-designed RCT is required to

  10. Moclobemide. A review of its pharmacological properties and therapeutic use in depressive illness.

    Fitton, A; Faulds, D; Goa, K L

    1992-04-01

    Moclobemide is a reversible and selective inhibitor of the enzyme monoamine oxidase (MAO) subtype A with a broad spectrum of antidepressant activity. Controlled clinical studies suggest that the short term clinical efficacy of moclobemide is significantly superior to that of placebo, and comparable to that of the tricyclic antidepressants clomipramine, amitriptyline, imipramine and desipramine, the irreversible MAO inhibitor tranylcypromine and the second-generation antidepressants maprotiline, mianserin and fluvoxamine in the treatment of major depressive illness. Moclobemide appears to be equally effective in endogenous and nonendogenous depression, producing marked amelioration of clinical features of psychomotor retardation and depressed mood. Moclobemide is well tolerated, being largely devoid of the anticholinergic adverse effects, symptomatic postural hypotension and weight gain variously associated with the tricyclic antidepressants and irreversible MAO inhibitors, and appears considerably safer on overdosage than the tricyclic and second generation antidepressants. Moreover, moclobemide offers the advantage over the older, irreversible MAO inhibitors of causing only minimal potentiation of the pressor response to dietary tyramine (the so-called 'cheese effect'). Consequently, the risk of potentially fatal hypertensive crisis, a major deterrent to the wider acceptance of these earlier compounds, is substantially reduced with moclobemide, and the need for dietary precautions is minimised. With its efficacy against endogenous and nonendogenous depression, relatively rapid onset of antidepressant activity, and absence of carry-over effects on treatment withdrawal, moclobemide is likely to make an important contribution to the treatment of major depressive illness. Its favourable tolerability profile, safety on overdosage and beneficial effect on age-related cognitive impairment may be of particular value in the elderly and those with concurrent physical

    Heart failure (HF) impacts an estimated 5.7 million Americans, and its prevalence is projected to increase to more than 8 million Americans in the next 15 years. Key clinical trials have established an evidence-based foundation for treatment of heart failure with reduced ejection fraction (HFrEF). Ivabradine and sacubitril/valsartan, which inhibit the f-channel and the angiotensin receptor and neprilysin, respectively, were recently approved by the Food and Drug Administration for HFrEF. In systolic heart failure, treatment with the If inhibitor ivabradine significantly reduced the combined endpoint of cardiovascular mortality or heart failure hospital admission vs placebo (P trial, sacubitril/valsartan significantly reduced the combined endpoint of cardiovascular death or heart failure hospitalization vs enalapril (P trials and their interplay with guideline-directed medical therapy. Ivabradine and sacubitril/valsartan increase pharmacotherapy options for the treatment of HFrEF but are not yet first-line agents. Clinical application will be better defined in the coming years as practitioners increase their familiarity with ivabradine and sacubitril/valsartan. PMID:26626162

    Full Text Available Brendan T Bowman, Mitchell H Rosner Division of Nephrology, University of Virginia Health System, Charlottesville, VA, USA Abstract: Hyponatremia is the most common electrolyte abnormality seen in clinical practice. Most cases of euvolemic or hypervolemic hyponatremia involve arginine vasopressin (AVP. AVP leads to a concentrated urine and negative free water clearance. Given this primary role of AVP, antagonizing its effect through blockade of its receptor in the distal tubule is an attractive therapeutic target. Lixivaptan is a newer, non-peptide, vasopressin type 2 receptor antagonist. Recent studies have demonstrated efficacy. This review summarizes the clinical pharmacology and data for this new agent.

    依佐加滨是首个治疗癫痫的神经元钾离子通道开放剂,己于2011年6月13日被美国FDA批准用于成人惊厥部分发作的治疗.其作用机制并未完全阐明,可能是通过稳定神经元钾离子通道使其保持“开放”状态,降低其若奋性而产生抗惊厥作用.其常见的不良反应有眩晕、嗜睡、乏力、意识错乱等.本文对依佐加滨的药理作用、药代动力学、药物相互作用、临床评价和安全性等进行介绍.%Ezogabine is the first neuronal potassium channel opener developed for the treatment of epilepsy. It was approved by the U. S. Food and Drug Administration on June 13, 2011 as an add-on medication to treat seizures associated with epilepsy in adults. The mechanism by which ezogabine exerts its therapeutic effects has not been fully elucidated. The drug may act as an anticonvulsant by reducing excitability through the stabilization of neuronal potassium channels in an "open" state. Studies indicate that ezogabine enhances transmembrane potassium currents mediated by the KCNQ family ion channels. By activating KCNQ channels, ezogabine is thought to stabilize the resting membrane potential and reduce brain excitability. The most common adverse effects were dizziness, drowsiness, fatigue and confusion, etc. The pharmacology, pharmaeokinetics, clinical evaluation, safety and drug interactions of ezogabine were reviewed in this paper.

    2012-04-01

    Conopeptides are a diverse group of recently evolved venom peptides used for prey capture and/or defense. Each species of cone snails produces in excess of 1000 conopeptides, with those pharmacologically characterized (≈ 0.1%) targeting a diverse range of membrane proteins typically with high potency and specificity. The majority of conopeptides inhibit voltage- or ligand-gated ion channels, providing valuable research tools for the dissection of the role played by specific ion channels in excitable cells. It is noteworthy that many of these targets are found to be expressed in pain pathways, with several conopeptides having entered the clinic as potential treatments for pain [e.g., pyroglutamate1-MrIA (Xen2174)] and one now marketed for intrathecal treatment of severe pain [ziconotide (Prialt)]. This review discusses the diversity, pharmacology, structure-activity relationships, and therapeutic potential of cone snail venom peptide families acting at voltage-gated ion channels (ω-, μ-, μO-, δ-, ι-, and κ-conotoxins), ligand-gated ion channels (α-conotoxins, σ-conotoxin, ikot-ikot, and conantokins), G-protein-coupled receptors (ρ-conopeptides, conopressins, and contulakins), and neurotransmitter transporters (χ-conopeptides), with expanded discussion on the clinical potential of sodium and calcium channel inhibitors and α-conotoxins. Expanding the discovery of new bioactives using proteomic/transcriptomic approaches combined with high-throughput platforms and better defining conopeptide structure-activity relationships using relevant membrane protein crystal structures are expected to grow the already significant impact conopeptides have had as both research probes and leads to new therapies.

  16. Triptans in migraine: a comparative review of pharmacology, pharmacokinetics and efficacy.

    2000-12-01

    Triptans are a new class of compounds developed for the treatment of migraine attacks. The first of the class, sumatriptan, and the newer triptans (zolmitriptan, naratriptan, rizatriptan, eletriptan, almotriptan and frovatriptan) display high agonist activity at mainly the serotonin 5-HT1B and 5-HT1D receptor subtypes. As expected for a class of compounds developed for affinity at a specific receptor, there are minor pharmacodynamic differences between the triptans. Sumatriptan has a low oral bioavailability (14%) and all the newer triptans have an improved oral bioavailability and for one, risatriptan, the rate of absorption is faster. The half-lives of naratriptan, eletriptan and, in particular, frovatriptan (26 to 30h) are longer than that of sumatriptan (2h). These pharmacokinetic improvements of the newer triptans so far seem to have only resulted in minor differences in their efficacy in migraine. Double-blind, randomised clinical trials (RCTs) comparing the different triptans and triptans with other medication should ideally be the basis for judging their place in migraine therapy. In only 15 of the 83 reported RCTs were 2 triptans compared, and in 11 trials triptans were compared with other drugs. Therefore, in all placebo-controlled randomised clinical trials, the relative efficacy of the triptans was also judged by calculating the therapeutic gain (i.e. percentage response for active minus percentage response for placebo). The mean therapeutic gain with subcutaneous sumatriptan 6mg (51%) was more than that for all other dosage forms of triptans (oral sumatriptan 100mg 32%; oral sumatriptan 50mg 29%: intranasal sumatriptan 20mg 30%; rectal sumatriptan 25mg 31%; oral zolmitriptan 2.5mg 32%; oral rizatriptan 10mg 37%; oral eletriptan 40mg 37%; oral almotriptan 12.5mg 26%). Compared with oral sumatriptan 100mg (32%), the mean therapeutic gain was higher with oral eletriptan 80mg (42%) but lower with oral naratriptan 2.5mg (22%) or oral frovatriptan 2.5mg (16

    2016-05-01

    Ophthalmic diseases include both those analogous to systemic diseases (eg, inflammation, infection, neuronal degeneration) and not analogous (eg, cataract, myopia). Many anterior segment diseases are treated pharmacologically through eye drops, which have an implied therapeutic index of local therapy. Unlike oral dosage forms administered for systemic diseases, eyedrops require patients not only to adhere to treatment, but to be able to accurately perform-ie, instill drops correctly. Anatomical and physiological barriers make topical delivery to the anterior chamber challenging-in some cases more challenging than absorption through the skin, nasal passages, or gut. Treatment of the posterior segment (eg, vitreous, retina, choroid, and optic nerve) is more challenging due to additional barriers. Recently, intravitreal injections have become a standard of care with biologics for the treatment of macular degeneration and other diseases. Although the eye has esterases, hydroxylases, and transporters, it has relatively little CYP450 enzymes. Because it is challenging to obtain drug concentrations at the target site, ocular clinical pharmacokinetics, and thus pharmacokinetic-pharmacodynamic interactions, are rarely available. Ophthalmic pharmaceuticals require consideration of solubility, physiological pH, and osmolarity, as well as sterility and stability, which in turn requires optimal pharmaceutics. Although applied locally, ocular medications may be absorbed systemically, which results in morbidity and mortality (eg, systemic hypotension, bronchospasm, and bradycardia). PMID:26360129

  1. Medetomidine sedation in dogs and cats: a review of its pharmacology, antagonism and dose.

    Science.gov (United States)

    Cullen, L K

    1996-09-01

    Medetomidine is a relatively new sedative analgesic in dogs and cats but some precautions are required when using it. It is a potent alpha 2-adrenoceptor agonist and stimulates receptors centrally to produce dose-dependent sedation and analgesia and receptors centrally and peripherally to cause marked bradycardia and decrease the cardiac output. While hypotension occurs frequently, higher doses of the sedative can raise the blood pressure due to an affect on peripheral receptors. Slowing of the respiratory rate is a frequent effect of medetomidine with some dogs showing signs of cyanosis. Other actions that follow medetomidine use are slowing of gastrointestinal motility, hypothermia, changes to endocrine function and, occasionally, vomiting and muscle twitching. The clinical use of medetomidine in dogs and cats is discussed. Recommended dose rates are presented along with precautions that should be taken when it is used alone for sedation, as an anaesthetic premedicant or in combination with ketamine, propofol or opioids. Hypoxaemia occurs frequently in dogs given medetomidine and propofol. The actions of medetomidine can be rapidly reversed with the specific alpha 2-adrenoceptor antagonist, atipamezole, which is an advantage because undesirable and sedative actions of medetomidine can be terminated.

    Effective clinical leadership is offered as the key to healthy, functional and supportive work environments for nurses and other health professionals. However, as a concept it lacks a standard definition and is poorly understood. This paper reports on an integrative review undertaken to uncover current understandings of defining attributes of contemporary clinical leadership in nursing. Data collection involved a search of relevant electronic databases for a 10-year period. Keywords for the search were 'clinical leadership' and 'nursing'. Ten research papers met the inclusion criteria for the integrative review. Analysis of these studies indicated clinical leadership attributes had a clinical focus, a follower/team focus or a personal qualities focus; attributes necessary to sustain supportive workplaces and build the capacity and resilience of nursing workforces. The small number of research-based studies yielded for the review indicates the need for further research in the area of clinical leadership. PMID:24099222

    Full Text Available Tamarind (Tamarindus indica, Fabaceae, a tropical fruit found in Africa and Asia is highly valued for its pulp. Tamarind fruit pulp has a sweet acidic taste due to a combination of high contents of tartaric acid and reducing sugars. The pulp is used for seasoning, in prepared foods, to flavour confections, curries and sauces, and as a major ingredient in juices and other beverages. Commercial tamarind-based drinks are available from many countries. Vitamin B content is quite high; carotene and vitamin C contents are low. Presence of tannins and other dyeing matters in the seed testa make the whole seed unsuitable for consumption, but they become edible after soaking and boiling in water. Tamarind kernel powder is an important sizing material in textile, paper and juteindustries. Seeds are gaining importance as an alternative source of proteins, and are besides rich in some essential minerals. Seed pectin can form gels over a wide pH range. Leaves and flowers can be eaten as vegetables, and are prepared in a variety of dishes. They are used to make curries, salads, stews and soups. Tamarind leaves are a fair source of vitamin C and α-carotene; mineral content is high, particularly P, K, Ca and Mg. Anti-oxidant, anti-inflammatory, anti-microbial and anti-fungal activity has been documented from several plant parts. Tamarind is also extensively used in traditional medicine. The traditional uses, its phytochemistry and pharmacognosy is reviewed to provided with a particular orientation to its value in sub-Sahara Africa.

    Full Text Available Investigation in the field of Alzheimer´s disease (AD, the commonest cause of dementia, has been very active in recent years and it may be difficult for the clinician to keep up with all the innovations and to be aware of the implications they have in clinical practice. The authors, thus, reviewed recent literature on the theme in order to provide the clinician with an updated overview, intended to support decision-making on aspects of diagnosis and management. This article begins to focus on the concept of AD and on its pathogenesis. Afterwards, epidemiology and non-genetic risk factors are approached. Genetics, including genetic risk factors and guidelines for genetic testing, are mentioned next. Recommendations for diagnosis of AD, including recently proposed criteria, are then reviewed. Data on the variants of AD is presented. First approach to the patient is dealt with next, followed by neuropsychological evaluation. Biomarkers, namely MRI, SPECT, FDG PET, PiB PET, CSF tau and Aβ analysis, as well as available data on their diagnostic accuracy, are also discussed. Factors predicting rate of disease progression are briefly mentioned. Finally, non-pharmacological and pharmacological treatments, including established and emerging drugs, are addressed.

    Full Text Available Silent, or clinically nonfunctioning adenomas are morphologically heterogeneous group, characterized by positive immunoreactivity for one or more hormones classically secreted by normal pituitary cells but without clinical expression. Although in some occasions enhanced or changed secretory activity can develop over time. According to immunoreactivity they are divided into "silent" gonado-, cortico-, somato -, mammo – and thyrotropinomas, oncocytomas, «zero-cell» tumors. All types of "silent" adenomas have different biological activity, secretory capacity and outcomes in the postoperative period. This series of clinical cases shows more «aggressiveness», a higher risk of relapse for "silent" cortico- and somatotropinomas. Immunohistochemical analysis of residual tissue can be used to identify patients with high risk of recurrence, to develop optimal treatment and follow-up.

    Philip Marcus Sinnett

    Full Text Available We examined the use of clinical trials registries in published systematic reviews and meta-analyses from clinical neurology. A review of publications between January 1, 2008 and December 31, 2014 from five neuroscience journals (Annals of Neurology, Brain, Lancet Neurology, Neurology, and The Neuroscientist was performed to identify eligible systematic reviews. The systematic reviews comprising the final sample were independently appraised to determine if clinical trials registries had been included as part of the search process. Studies acknowledging the use of a trials registry were further examined to determine whether trial data had been incorporated into the analysis. The initial search yielded 194 studies, of which 78 systematic reviews met the selection criteria. Of those, five acknowledged the use of a specific clinical trials registry: four reviewed unpublished trial data and two incorporated unpublished trial data into their results. Based on our sample of systematic reviews, there was no increase in the use of trials registries in systematic review searches over time. Few systematic reviews published in clinical neurology journals included data from relevant clinical trials registries.

    Full Text Available Michele IesterClinica Oculistica, University of Genoa, ItalyAbstract: Brinzolamide is a white powder commercially formulated as a 1% ophthalmic suspension to reduce intraocular pressure (IOP. Pharmacologically, brinzolamide is a highly specific, non-competitive, reversible, and effective inhibitor of carbonic anhydrase II (CA-II, able to suppress formation of aqueous humor in the eye and thus to decrease IOP. Several clinical trials have evaluated its safety and the most commonly ocular adverse events are blurred vision (3%–8%, ocular discomfort (1.8%–5.9%, and eye pain (0.7%–4.0%. Brinzolamide has been introduced to treat ocular hypertension and primary open-angle glaucoma. In some clinical studies it has been estimated that brinzolamide reduced IOP by was about 18%. Brinzolamide can be added to beta-blockers and prostaglandins. In the latter combination, because prostaglandin derivatives improve the uveoscleral outflow but also increase the activity of CA in ciliary epithelium with a secondary increase in aqueous humor secretion, and slightly reduce the efficacy of prostaglandin analogues, theoretically topical CA inhibitors (CAI decrease IOP by inhibiting CA-II, thus improving prostaglandin efficacy as well as lowering IOP. Brinzolamide could have a secondary possible effect on ocular flow too. Some clinical studies showed a mild improvement of ocular blood flow. Theoretically, CAI could give rise to metabolic acidosis, with secondary vasodilatation and improvement of blood flow. Systemic acidosis can occur in the setting of oral CAI therapy, and local acidosis within ocular tissues is theoretically possible with topical CAI therapy, with the potential for a local increase in ocular blood flow. In conclusion, topical CAI treatment has efficacy in IOP-lowering ranging from 15% to 20%. From published data, brinzolamide can be used as first-line medication, even if other medications have a higher efficacy, with few side effects and it is a

    2008-01-01

    The aim of the present review is to summarize the current knowledge regarding pharmacological prevention and treatment of acute pancreatitis (AP)based on experimental animal models and clinical trials.Somatostatin (SS) and octreotide inhibit the exocrine production of pancreatic enzymes and may be useful as prophylaxis against Post Endoscopic retrograde cholangiopancreatography Pancreatitis (PEP). The protease inhibitor Gabexate mesilate (GM) is used routinely as treatment to AP in some countries, but randomized clinical trials and a meta-analysis do not support this practice. Nitroglycerin (NGL) is a nitrogen oxide (NO) donor, which relaxes the sphincter of Oddi.Studies show conflicting results when applied prior to ERCP and a large multicenter randomized study is warranted. Steroids administered as prophylaxis against PEP has been validated without effect in several randomized trials. The non-steroidal anti-inflammatory drugs (NSAID) indomethacin and diclofenac have in randomized studies showed potential as prophylaxis against PEP. Interleukin 10 (IL-10) is a cytokine with anti-inflammatory properties but two trials testing IL-10 as prophylaxis to PEP have returned conflicting results.Antibodies against tumor necrosis factor-alpha (TNF-α)have a potential as rescue therapy but no clinical trials are currently being conducted. The antibiotics betalactams and quinolones reduce mortality when necrosis is present in pancreas and may also reduce incidence of infected necrosis. Evidence based pharmacological treatment of AP is limited and studies on the effect of potent anti-inflammatory drugs are warranted.

    After a single dose, lithium, usually given as carbonate, reaches a peak plasma concentration at 1.0-2.0 hours for standard-release dosage forms, and 4-5 hours for sustained-release forms. Its bioavailability is 80-100%, its total clearance 10-40 mL/min and its elimination half-life is 18-36 hours. Use of the sustained-release formulation results in 30-50% reductions in peak plasma concentrations without major changes in the area under the plasma concentration curve. Lithium distribution to the brain, evaluated using 7Li magnetic resonance spectroscopy, showed brain concentrations to be approximately half those in serum, occasionally increasing to 75-80%. Brain concentrations were weakly correlated with serum concentrations. Lithium is almost exclusively excreted via the kidney as a free ion and lithium clearance is considered to decrease with aging. No gender- or race-related differences in kinetics have been demonstrated. Renal insufficiency is associated with a considerable reduction in renal clearance of lithium and is considered a contraindication to its use, especially if a sodium-poor diet is required. During the last months of pregnancy, lithium clearance increases by 30-50% as a result of an increase in glomerular filtration rate. Lithium also passes freely from maternal plasma into breast milk. Numerous kinetic interactions have been described for lithium, usually involving a decrease in the drug's clearance and therefore increasing its potential toxicity. Clinical pharmacology studies performed in healthy volunteers have investigated a possible effect of lithium on cognitive functions. Most of these studies reported a slight, negative effect on vigilance, alertness, learning and short-term memory after long-term administration only. Because of the narrow therapeutic range of lithium, therapeutic monitoring is the basis for optimal use and administration of this drug. Lithium dosages should be adjusted on the basis of the serum concentration drawn

Bronchodilator therapy is the cornerstone in COPD treatment. Bronchodilation in COPD is mainly achieved via administration of long- and ultralong-acting β2-agonists and with long-acting muscarinic antagonists. New combinations of bronchodilators with dual-acting muscarinic antagonist and β2-agonist properties have been licensed, and others are currently being developed with the aim of achieving once-daily dosing, and therefore may improve the likelihood of treatment compliance. These combination bronchodilators include glycopyrronium bromide/indacaterol maleate, umeclidinium (UMEC bromide/vilanterol trifenatate (VI, aclidinium bromide/formoterol and tiotropium bromide/olodaterol (Boehringer Ingelheim, Germany. This review will focus mainly on studies and clinical trials involving the novel fixed-dose combination of UMEC/VI at doses of 125/25 µg and 62.5/25 µg in patients with COPD. Data from large clinical trials involving more than 4,500 COPD patients indicate that UMEC/VI is an effective once-daily treatment in COPD with improved pulmonary function. Future studies assessing the impact of this combination on exacerbations, delay in disease progression, and health status in patients with COPD are warranted.

  9. Headache and sleep disorders: review and clinical implications for headache management.

    Science.gov (United States)

    Rains, Jeanetta C; Poceta, J Steven

    2006-10-01

    Review of epidemiological and clinical studies suggests that sleep disorders are disproportionately observed in specific headache diagnoses (eg, migraine, tension-type, cluster) and other nonspecific headache patterns (ie, chronic daily headache, "awakening" or morning headache). Interestingly, the sleep disorders associated with headache are of varied types, including obstructive sleep apnea (OSA), periodic limb movement disorder, circadian rhythm disorder, insomnia, and hypersomnia. Headache, particularly morning headache and chronic headache, may be consequent to, or aggravated by, a sleep disorder, and management of the sleep disorder may improve or resolve the headache. Sleep-disordered breathing is the best example of this relationship. Insomnia is the sleep disorder most often cited by clinical headache populations. Depression and anxiety are comorbid with both headache and sleep disorders (especially insomnia) and consideration of the full headache-sleep-affective symptom constellation may yield opportunities to maximize treatment. This paper reviews the comorbidity of headache and sleep disorders (including coexisting psychiatric symptoms where available). Clinical implications for headache evaluation are presented. Sleep screening strategies conducive to headache practice are described. Consideration of the spectrum of sleep-disordered breathing is encouraged in the headache population, including awareness of potential upper airway resistance syndrome in headache patients lacking traditional risk factors for OSA. Pharmacologic and behavioral sleep regulation strategies are offered that are also compatible with treatment of primary headache. PMID:17040332

  12. The ART approach: clinical aspects reviewed

    Gustavo Fabián Molina

    2009-01-01

    Full Text Available The success of ART as a caries management approach is supported by more than 20 years of scientific evidence. ART follows the contemporary concepts of modern cariology and restorative dentistry. It challenges treatment concepts such as step-wise excavation and the need for complete removal of affected dentine. The ART approach so far has mainly used high-viscosity glass-ionomer as the sealant and restorative material. Cariostatic and remineralization properties have been ascribed to this material which requires further research to establish its clinical relevance. The adhesion of high-viscosity glass-ionomer to enamel in pits and fissures is apparently strong, as its remnants, blocking the pits and fissures, have been considered a possible reason for the low prevalence of carious lesion development after the glass-ionomer has clinically disappeared from it. Encapsulated high-viscosity glass-ionomers may lead to higher restoration survival results than those of the hand-mixed version and should, therefore, not be neglected when using ART. Similarly, the use of resin-modified glass-ionomer with ART should be researched. The effectiveness of ART when compared to conventional caries management approaches has been shown in numerous studies. Proper case selection is an important factor for long-lasting ART restoration survival. This is based on the caries risk situation of the individual, the size of the cavity opening, the strategic position of the cavitated tooth and the presence of adequate caries control measures. As the operator is one of the main causes for failure of ART restorations, attending a well-conducted ART training course is mandatory for successful implementation of ART.

    The recent focus of federal funding on comparative effectiveness research underscores the importance of clinical trials in the practice of evidence-based medicine and health care reform. The impact of clinical trials not only extends to the individual patient by establishing a broader selection of effective therapies, but also to society as a whole by enhancing the value of health care provided. However, clinical trials also have the potential to pose unknown risks to their participants, and biased knowledge extracted from flawed clinical trials may lead to the inadvertent harm of patients. Although conducting a well-designed clinical trial may appear straightforward, it is founded on rigorous methodology and oversight governed by key ethical principles. In this review, we provide an overview of the ethical foundations of trial design, trial oversight, and the process of obtaining approval of a therapeutic, from its pre-clinical phase to post-marketing surveillance. This narrative review is based on a course in clinical trials developed by one of the authors (DJM), and is supplemented by a PubMed search predating January 2011 using the keywords "randomized controlled trial," "patient/clinical research," "ethics," "phase IV," "data and safety monitoring board," and "surrogate endpoint." With an understanding of the key principles in designing and implementing clinical trials, health care providers can partner with the pharmaceutical industry and regulatory bodies to effectively compare medical therapies and thereby meet one of the essential goals of health care reform.

    Full Text Available Objective: The main objective of this study is to know clinical trials in nutshell and phase 0 clinical trial are to establish at the very earliest opportunity-before large numbers of patients have been accrued and exposed to potential drug-associated toxicity-whether an agent is modulating its target in a tumor, and consequently whether further clinical development is warranted. We review here the fundamental requirements of clinical studies conducted under an exploratory IND and address some common misconceptions regarding phase 0 trials. Phase 0 clinical trials, developed in response to the United States Food and Drug Administration (FDA's recent exploratory Investigational New Drug (IND guidance, and are intended to expedite the clinical evaluation of new molecular entities. The exploratory IND supports the performance of first-in-human testing of new investigational agents at subtherapeutic doses based on reduced manufacturing and toxicologic requirements, allowing the demonstration of drug-target effects and assessment of pharmacokinetic-pharmacodynamic relationships in humans earlier in clinical development. Conclusion: From this present review study, we concluded that Phase “0” in clinical trials can work as a useful parameter to measure drug safety at subtherapeutic level and the fundamental requirements of clinical studies conducted under an exploratory IND and address some common misconceptions regarding phase 0 trials.

  17. Transcatheter therapies for resistant hypertension: Clinical review

    2014-01-01

    Resistant hypertension(RHTN) is a commonly encountered clinical problem and its management remains a challenging task for healthcare providers. The prevalence of true RHTN has been difficult to assess due to pseudoresistance and secondary hypertension. Atherosclerotic renal artery stenosis(RAS) has been associated as a secondary cause of RHTN. Initial studies had shown that angioplasty and stenting for RAS were a promising therapeutic option when added to optimal medical management. However, recent randomized controlled trials in larger populations have failed to show any such benefit. Sympathetic autonomic nervous system dysfunction is commonly noted in individuals with resistant hypertension. Surgical sympathectomy was the treatment of choice for malignant hypertension and it significantly improved mortality. However, postsurgical complications and the advent of antihypertensive drugs made this approach less desirable and it was eventually abandoned. Increasing prevalence of RHTN in recent decades has led to the emergence of minimally invasive interventions such as transcatheter renal denervation for better control of blood pressure. It is a minimally invasive procedure which uses radiofrequency energy for selective ablation of renal sympathetic nerves located in the adventitia of the renal artery. It is a quick procedure and has a short recovery time. Early studies in small population showed significant reduction in blood pressure. The most recent Symplicity HTN-3 study, which is the largest randomized control trial and the only one to use a sham procedure in controls, failed to show significant BP reduction at 6 mo.

    Full Text Available Diabetes insipidus (DI is a complex disease. DI is inability of the body to conserve water. Polydipsia and polyuria are the major manifestations of DI. DI has various variants including central diabetes insipidus (due to defect in ADH secretion, nephrogenic diabetes insipidus (due to defect in ADH receptors or urea receptors, gestational diabetes insipidus (due to catabolism of ADH by placental vasopressinase and primary polydipsia (due to massive fluid intake. The cause of various variants of DI is either acquired or congenital. High plasma osmolality due to hypotonic urine excretion can be fatal because it can cause psychosis, lethargy, seizures, coma or even death. Polyuria and polydipsia help in the diagnosis of DI. Differential diagnosis of various variants of DI can be carried out on the basis of water deprivation test, MRI and other radiological techniques. The proper management of DI is the replenishment of water loss and correction of clinical presentations produced as a result of DI, major is hypernatremia. The best management for primary polydipsia is fluid restriction while fluid intake is used for adipsic diabetes insipidus. ADH replacement therapy is widely used to treat DI. DDAVP or desmopressin is mostly preferred ADH analogue because it has less side effects and resistant to placental vasoprssinase. [Int J Res Med Sci 2016; 4(1.000: 5-11

    Vitamin D (vitD) is known for its essential role in calcium homeostasis and bone health. VitD is made endogenously in the skin from UVB radiation from sunlight. VitD is now considered as a potent neurosteroid hormone, critical to brain development and normal brain function, and is known for its anti-inflammatory property affecting various aspects of human health. VitD ligand-receptor, a receptor that mediates much of vitD's biological actions, has been found throughout the body including the central nervous system. VitD deficiency is common in patients with severe mental illness such as schizophrenia. Schizophrenia is a debilitating chronic mental illness characterised by positive symptoms, such as hallucinations and delusions, and negative symptoms including flat affect and lack of motivation. Several environmental risk factors for schizophrenia, such as season of birth, latitude and migration, have been linked to vitD deficiency. Recent studies have suggested a potential role of vitD in the development of schizophrenia. For example, neonatal vitD status is associated with the risk of developing schizophrenia in later life obesity, insulin resistance, diabetes, hyperlipidaemia and cardiovascular disease, which are commonly seen in patients with schizophrenia. It has been well established that vitD deficiency is related to these metabolic problems. The biological mechanism is most likely related to vitD's action on the regulation of inflammatory and immunological processes, consequently affecting the manifestation of clinical symptoms and treatment response of schizophrenia. Potential benefits of vitD supplementation to improve schizophrenia symptoms as well as physical health in patients with schizophrenia should be further explored in future studies. PMID:26767392

    Since the introduction of the Prospective Payment System based on Diagnosis Related Groups (DRGs) in the U.S.A., important information technologies are arising. We discuss how Professional Review Organizations, (PROS) are forcing a better control of appropriateness and quality of medical care. Hospitals should have the internal capabilities to perform, at least, the same reviews as performed by the PROs. Concurrent Clinical Review Systems based on DRGs are a special type of information technology that take place during and even before patient hospitalization, therefore allowing an 'on line' monitoring information. Low-cost microcomputers are playing a major role in the popularization of this technology. 'Clinical Review System' is a microcomputer-based software that renders easy and feasible and otherwise complex task.

    In management of AD, pharmacological treatment alone using acetylcholinesterase inhibitor (AChEI) is general consensus, and provides beneficial effect to prolong their progression. Combined non-pharmacological therapy, especially cognitive therapy is recently having attention with expectation of improvement in cognitive ability. This study examined the effect of combined cognitive therapy in AD patients who were maintaining AChEI using FDG PET. Four patients (689 yrs) who diagnosed as probable Alzheimer's disease based on the NINCDS-ADRDA criteria participated in this study. 12-week cognitive therapy comprised seven fields to enhance orientation, memory, recall, visuo-motor organization, categorization and behavior modification/sequencing. They received 45-minute sessions twice per week with maintaining their previous medication. Clinical improvement was assessed by comprehensive neuropsychological tests. Two FDG PET studies were performed before cognitive therapy and in the middle of the therapy, and compared to evaluate the effect of cognitive therapy to cerebral metabolism. Two of 4 patients whose initial cognitive impairment was milder had clinical improvement after 12 weeks, the rest who were more severely impaired failed to have clinical improvement. Regional cerebral hypometabolism on initial PET was correlated with their functional status. Follow up PET of two responders demonstrated the increases in regional metabolism in the temporal and/or frontal cortex, which was associated their functional improvement. Cerebral metabolism in poor responders were minimally increased or no changed. This preliminary data suggests that cognitive therapy is potentially useful to stabilize or improve cognitive and functional performance in AD patients with relatively mild cognitive dysfunction. And FDG PET could demonstrate possible candidates for cognitive therapy and the effect of the therapy.

    Clinical trials are critical for the development of new therapies in dermatology, and their results help determine US Food and Drug Administration (FDA) approval and guide care. Of special relevance is the clinical trial efficacy end point, the metric from which statistically significant outcome is derived. Clinicians' understanding of a clinical trial's end point is necessary for critical analysis of the trial results and for applying those results to daily practice. This review provides practical knowledge and critical evaluation of end points used in treatment approvals by the FDA. The end points for actinic keratosis, acne vulgaris, atopic dermatitis, onychomycosis, and cutaneous ulcer serve as examples. PMID:26936300

  7. Value of 1.0-M gadolinium chelates: review of preclinical and clinical data on gadobutrol

    International Nuclear Information System (INIS)

    Several preclinical and clinical studies with the first commercially available highly concentrated Gd-chelate gadobutrol (1 mol/l) are reviewed. Physicochemical, pharmacological, and pharmacokinetic properties, safety analysis, as well as experimental and clinical efficacy studies are highlighted in comparison with 0.5-M Gd-chelates. The 1-mol gadobutrol has been proven to be safe in an examined dose range from 0.04 up to 0.5 mmol/kg body weight (b.w.). Even in patients with chronic renal impairment, including hemodialysis, gadobutrol can safely be applied at doses up to 0.3 mmol/kg b.w. For contrast-enhanced MRI in the equilibrium phase, efficacy data analysis shows comparable results to other commercially available extracellular Gd-chelates with lower Gd-concentrations (0.5 M). Studies focused on the potential benefit of a tighter bolus, such as brain perfusion imaging using T2*-effects, document the superiority of a highly concentrated Gd contrast agent. For contrast-enhanced MRA, clinical studies are still ongoing; therefore, the ultimate potential of a more compact bolus, using 1-M Gd-chelates, for contrast-enhanced MRI, has still to be analyzed, especially for time-resolved magnetic resonance angiography.

    Skype is a popular and free software application that allows PCs and mobile devices to be used for video communication over the Internet. We reviewed the literature to determine whether the clinical use of Skype is supported by evidence. One small (n = 7) controlled clinical trial had assessed the effect of nursing communication using Skype on elderly patients with dementia and their carers. However, we were unable to identify any large, well-designed studies which had formally evaluated the safety, clinical effectiveness, security and privacy of Skype for the routine delivery of patient care. While there were many case reports and small studies, no firm evidence either in favour of, or against the use of Skype for clinical telehealth was found. The risks and benefits of using Skype for clinical purposes are not known. PMID:22362829

    To date, pharmacological treatments for mood and anxiety disorders and for drug dependence show limited efficacy, leaving a large number of patients suffering severe and persistent symptoms. Preliminary studies in animals and humans suggest that ayahuasca, psilocybin and lysergic acid diethylamide (LSD) may have antidepressive, anxiolytic, and antiaddictive properties. Thus, we conducted a systematic review of clinical trials published from 1990 until 2015, assessing these therapeutic properties. Electronic searches were performed using the PubMed, LILACS, and SciELO databases. Only clinical trials published in peer-reviewed journals were included. Of these, 151 studies were identified, of which six met the established criteria. Reviewed studies suggest beneficial effects for treatment-resistant depression, anxiety and depression associated with life-threatening diseases, and tobacco and alcohol dependence. All drugs were well tolerated. In conclusion, ayahuasca, psilocybin and LSD may be useful pharmacological tools for the treatment of drug dependence, and anxiety and mood disorders, especially in treatment-resistant patients. These drugs may also be useful pharmacological tools to understand psychiatric disorders and to develop new therapeutic agents. However, all studies reviewed had small sample sizes, and half of them were open-label, proof-of-concept studies. Randomized, double-blind, placebo-controlled studies with more patients are needed to replicate these preliminary findings. PMID:27354908

  11. A Review of the Receptor-Binding Properties of p-Synephrine as Related to Its Pharmacological Effects

    2011-01-01

    Full Text Available Bitter orange (Citrus aurantium extract and its primary protoalkaloid p-synephrine are used widely in weight loss/weight management and sports performance products. Because of structural similarities, the pharmacological effects of p-synephrine are widely assumed to be similar to those of ephedrine, m-synephrine (phenylephrine, and endogenous amine neurotransmitters as norepinephrine and epinephrine. However, small structural changes result in the receptor binding characteristics of these amines that are markedly different, providing a plausible explanation for the paucity of adverse effects associated with the wide-spread consumption of p-synephrine in the form of dietary supplements as well as in various Citrus foods and juices. This paper summarizes the adrenoreceptor binding characteristics of p-synephrine relative to m-synephrine, norepinephrine, and other amines as related to the observed pharmacological effects.

    2013-07-01

    We sought to assess the comparative effectiveness and safety of pharmacologic and mechanical strategies to prevent venous thromboembolism (VTE) in patients undergoing bariatric surgery. We searched (through August 2012) for primary studies that had at least 2 different interventions. Of 30,902 citations, we identified 8 studies of pharmacologic strategies and 5 studies of filter placement. No studies randomized patients to receive different interventions. One study suggested that low-molecular-weight heparin is more efficacious than unfractionated heparin in preventing VTE (0.25% vs 0.68%, P prevent VTE better than inpatient treatment only. There was insufficient evidence supporting the hypothesis that filters reduce the risk of pulmonary embolism, with a point estimate suggesting increased rates with filters (pooled relative risk [RR], 1.21 95% CI, 0.57-2.56). There was low-grade evidence that filters are associated with higher mortality (pooled RR, 4.30 95% CI, 1.60-11.54) and higher deep vein thrombosis rates (2.94 1.35-6.38). There was insufficient evidence to support that augmented subcutaneous enoxaparin doses (>40 mg daily or 30 mg twice daily) are more efficacious than standard dosing, with a trend toward increased bleeding. Of note, for both filters and augmented pharmacologic dosing strategies, patients at highest risk for VTE were more likely to receive more intensive interventions, limiting our ability to attribute outcomes to prophylactic strategies used.

    Full Text Available Drug discovery is a risky, costly and time-consuming process depending on multidisciplinary methods to create safe and effective medicines. Although considerable progress has been made by high-throughput screening methods in drug design, the cost of developing contemporary approved drugs did not match that in the past decade. The major reason is the late-stage clinical failures in Phases II and III because of the complicated interactions between drug-specific, human body and environmental aspects affecting the safety and efficacy of a drug. There is a growing hope that systems-level consideration may provide a new perspective to overcome such current difficulties of drug discovery and development. The systems pharmacology method emerged as a holistic approach and has attracted more and more attention recently. The applications of systems pharmacology not only provide the pharmacodynamic evaluation and target identification of drug molecules, but also give a systems-level of understanding the interaction mechanism between drugs and complex disease. Therefore, the present review is an attempt to introduce how holistic systems pharmacology that integrated in silico ADME/T (i.e., absorption, distribution, metabolism, excretion and toxicity, target fishing and network pharmacology facilitates the discovery of small molecular drugs at the system level.

    2015-01-01

    Relaxin, insulin-like peptide 3 (INSL3), relaxin-3, and INSL5 are the cognate ligands for the relaxin family peptide (RXFP) receptors 1–4, respectively. RXFP1 activates pleiotropic signaling pathways including the signalosome protein complex that facilitates high-sensitivity signaling; coupling to Gαs, Gαi, and Gαo proteins; interaction with glucocorticoid receptors; and the formation of hetero-oligomers with distinctive pharmacological properties. In addition to relaxin-related ligands, RXFP1 is activated by Clq-tumor necrosis factor-related protein 8 and by small-molecular-weight agonists, such as ML290 [2-isopropoxy-N-(2-(3-(trifluoromethylsulfonyl)phenylcarbamoyl)phenyl)benzamide], that act allosterically. RXFP2 activates only the Gαs- and Gαo-coupled pathways. Relaxin-3 is primarily a neuropeptide, and its cognate receptor RXFP3 is a target for the treatment of depression, anxiety, and autism. A variety of peptide agonists, antagonists, biased agonists, and an allosteric modulator target RXFP3. Both RXFP3 and the related RXFP4 couple to Gαi/Gαo proteins. INSL5 has the properties of an incretin; it is secreted from the gut and is orexigenic. The expression of RXFP4 in gut, adipose tissue, and β-islets together with compromised glucose tolerance in INSL5 or RXFP4 knockout mice suggests a metabolic role. This review focuses on the many advances in our understanding of RXFP receptors in the last 5 years, their signal transduction mechanisms, the development of novel compounds that target RXFP1–4, the challenges facing the field, and current prospects for new therapeutics.

    1996-09-01

    A well-established study group undertook a pilot peer review project testing the use of clinical audit in members' practices. Two peer review groups were formed involving a total of 16 practices. Practice visits were undertaken and a series of meetings were held to prepare and discuss the various projects. The progress of the groups was monitored by questionnaires. All practitioners reported benefits from the project (specifically, from the practice visits) and made changes in areas of their practice other than those specifically chosen for their project. The benefits of carrying out audit projects in a peer review setting are stressed as are the benefits of reciprocal practice visits. The importance of prior establishment of mutual trust and confidence in the peer review group is emphasised. PMID:10332335

    Heparin-induced thrombocytopenia is a profoundly dangerous, potentially lethal, immunologically mediated adverse drug reaction to unfractionated heparin or, less commonly, to low-molecular weight heparin. In this comprehensive review, the authors highlight heparin-induced thrombocytopenia's risk factors, clinical presentation, pathophysiology, diagnostic principles, and treatment. The authors place special emphasis on the management of patients requiring procedures using cardiopulmonary bypass or interventions in the catheterization laboratory. Clinical vigilance of this disease process is important to ensure its recognition, diagnosis, and treatment. Misdiagnosis of the syndrome, as well as misunderstanding of the disease process, continues to contribute to its morbidity and mortality. PMID:27230048

    2014-01-01

    Full Text Available In the current modern and global society, social changes are in constant evolution due to scientific progress (technology, culture, customs, and hygiene and produce the freedom in individuals to take decisions by themselves or with their doctors toward drug consumption. In the arena of marketed drug products which includes society, individual, administration, and pharmaceutical industry, the young discipline emerged is social pharmacology or sociopharmacology. This science arises from clinical pharmacology, and deals with different parameters, which are important in creating knowledge on marketed drugs. However, the scope of "social pharmacology" is not covered by the so-called "Phase IV" alone, but it is the science that handles the postmarketing knowledge of drugs. The social pharmacology studies the "life cycle" of any marketed pharmaceutical product in the social terrain, and evaluates the effects of the real environment under circumstances totally different in the drug development process. Therefore, there are far-reaching horizons, plural, and shared predictions among health professionals and other, for beneficial use of a drug, toward maximizing the benefits of therapy, while minimizing negative social consequences.

Research suggests that not only can it be useful in promoting maintenance of alcohol abstinence but also it may play a key role in decreasing alcohol cravings and anxiety often associated with alcohol dependence. To assess the benefit of baclofen for alcohol dependence, a review of the literature was conducted to identify published data investigating this off-label treatment. Four randomized controlled trials to date have been published and were included in this review. Although primary outcomes differ between studies, patients randomized to baclofen experience higher rates of abstinence from alcohol than those taking placebo in two of the trials. Secondary analyses indicate that baclofen is safe in patients with alcohol dependence, including those with moderate to severe liver cirrhosis, and may provide beneficial anxiolytic effects. Despite some positive data, the largest available randomized controlled trial failed to find any differences between baclofen and placebo. In all studies, individuals with severe medical comorbidities, seizure disorders, and psychiatric disorders were excluded from trials, which may limit external validity. In summary, there may be beneficial effects from using baclofen for the treatment of alcohol dependence; however, limited conclusions can be drawn from the small number of studies

    Gaining experience in clinical mental health settings is central to the education of health practitioners. To facilitate the ongoing development of knowledge and practice in this area, we performed a review of the literature on clinical placements in mental health settings. Searches in Academic Search Complete, CINAHL, Medline and PsycINFO databases returned 244 records, of which 36 met the selection criteria for this review. Five additional papers were obtained through scanning the reference lists of those papers included from the initial search. The evidence suggests that clinical placements may have multiple benefits (e.g. improving students' skills, knowledge, attitudes towards people with mental health issues and confidence, as well as reducing their fears and anxieties about working in mental health). The location and structure of placements may affect outcomes, with mental health placements in non-mental health settings appearing to have minimal impact on key outcomes. The availability of clinical placements in mental health settings varies considerably among education providers, with some students completing their training without undertaking such structured clinical experiences. Students have generally reported that their placements in mental health settings have been positive and valuable experiences, but have raised concerns about the amount of support they received from education providers and healthcare staff. Several strategies have been shown to enhance clinical placement experiences (e.g. providing students with adequate preparation in the classroom, implementing learning contracts and providing clinical supervision). Educators and healthcare staff need to work together for the betterment of student learning and the healthcare professions. PMID:25397660

    2006-12-01

    The changes in diet associated with the development of a more affluent lifestyle have been considered one of the environmental factors that may have contributed to the rise in the prevalence of asthma over the past few decades, and dietary sodium has been considered to be a dietary constituent which may be implicated in this phenomenon. The data presented in this review demonstrate that adoption of a low sodium diet for a period of 2-5 weeks may improve lung function and decrease bronchial reactivity in adults with asthma, while sodium loading appears to have a detrimental effect. Similarly, a low sodium diet maintained for 1-2 weeks decreases bronchoconstriction in response to exercise in individuals with asthma. There is no data as to the longer-term effect of a low sodium diet on either the prevalence or severity of asthma or on exercise-induced bronchoconstriction. As a low sodium diet has other beneficial health effects, it can be considered as a therapeutic option for adults with asthma, although it should be considered as an adjunctive intervention to supplement optimal pharmacological management of asthma and not as an alternative. If the relationship between higher sodium intake and increased prevalence and severity of asthma is causal, then there are potential population benefits for asthma as well as cardiovascular disease to be derived from public health measures to reduce sodium consumption.

    Acute high-altitude illness is an encompassing term for the range of pathology that the unacclimatised individual can develop at increased altitude. This includes acute mountain sickness, high-altitude cerebral oedema and high-altitude pulmonary oedema. These conditions represent an increasing clinical problem as more individuals are exposed to the hypobaric hypoxic environment of high altitude for both work and leisure. In this review of acute high-altitude illness, the epidemiology, risk fa...

    2016-01-01

    The current treatment of Parkinson’s disease with dopamine-centric approaches such as L-DOPA and dopamine agonists, although very successful, is in need of alternative treatment strategies, both in terms of disease modification and symptom management. Various non-dopaminergic treatment approaches did not result in a clear clinical benefit, despite showing a clear effect in preclinical animal models. In addition, polypharmacy is common, sometimes leading to unintended effects on non-motor cogn...

  16. Review of rank-based procedures for multicenter clinical trials.

    2013-01-01

    This article reviews nonparametric alternatives to the mixed model normal theory analysis for the analyses of multicenter clinical trials. Under a mixed model, the traditional analysis is based on maximum likelihood theory under normal errors. This analysis, though, is not robust to outliers. Robust, rank-based, Wilcoxon-type procedures are reviewed for a multicenter clinical trial for the mixed model but without the assumption of normality. These procedures retain the high efficiency of Wilcoxon methods for simple location problems and are based on a fitting criterion which is robust to outliers in response space. A simple weighting scheme can be employed so that the procedures are robust to outliers in factor (design) space as well as response space. These rank-based analyses offer a complete analysis, including estimation of fixed effects and their standard errors, and tests of linear hypotheses. Both rank-based estimates of contrasts and individual treatment effects are reviewed. We illustrate the analyses using real data from a clinical trial. PMID:24138428

    2015-02-01

    Full Text Available Electronic textiles have potential for many practical uses in clinical rehabilitation. This scoping review appraises recent and emerging developments of textile-based sensors with applications to rehabilitation. Contributions published from 2009 to 2013 are appraised with a specific focus on the measured physiological or biomechanical phenomenon, current measurement practices, textile innovations, and their merits and limitations. While fabric-based signal quality and sensor integration have advanced considerably, overall system integration (including circuitry and power has not been fully realized. Validation against clinical gold standards is inconsistent at best, and feasibility with clinical populations remains to be demonstrated. The overwhelming focus of research and development has been on remote sensing but the opportunity for textile-mediated feedback to the wearer remains unexplored. Recommendations for future research are provided.

    The longevity of fixed partial denture depends on the type of luting cement used with tooth preparation. The clinician's understating of various cements, their advantages and disadvantages is of utmost importance. In recent years, many luting agents cements have been introduced claiming clinically better performance than existing materials due to improved characteristics. Both conventional and contemporary dental luting cements are discussed here. The various agents discussed are: Zinc phosphate, Zinc polycarboxylate, Zinc oxide-eugenol, Glass-ionomer, Resin modified GIC, Compomers and Resin cement. The purpose of this article is to provide a discussion that provides a clinical perspective of luting cements currently available to help the general practitioner make smarter and appropriate choices.

    2016-02-01

    Recently, the complexity and costs of clinical trials have increased dramatically, especially in the area of new drug development. Risk-based monitoring (RBM) has been attracting attention as an efficient and effective trial monitoring approach, which can be applied irrespectively of the trial sponsor, i.e., academic institution or pharmaceutical company. In the RBM paradigm, it is expected that a statistical approach to central monitoring can help improve the effectiveness of on-site monitoring by prioritizing and guiding site visits according to central statistical data checks, as evidenced by examples of actual trial datasets. In this review, several statistical methods for central monitoring are presented. It is important to share knowledge about the role and performance capabilities of statistical methodology among clinical trial team members (i.e., sponsors, investigators, data managers, monitors, and biostatisticians) in order to adopt central statistical monitoring for assessing data quality in the actual clinical trial.

    1986-01-01

    A review of 50 patients with a clinical ecology diagnosis of environmentally induced illness is reported. Histories were extremely heterogeneous. Eight patients had no symptoms or disease, 11 had symptoms caused by preexisting nonenvironmental disease, and 31 had multiple subjective symptoms. No consistent physical findings or laboratory abnormalities were found. Serum levels of immunoglobulins and complement, and circulating lymphocyte, B-cell, T-cell, and T-cell subset counts were not significantly abnormal. The diagnostic provocation-neutralization procedure, environmental restrictions, and dietary advice of clinical ecology produced further symptoms and fear of environmental and food contaminants. The patients with chronic multisystem complaints had characteristic symptoms of psychosomatic illness, but this study does not support the clinical ecology theory that psychosomatic illness may be an expression of food and chemical sensitivities induced by the toxic effect of environmental chemicals on the immune system.

  1. Prevention of cardiovascular disease guided by total risk estimations - challenges and opportunities for practical implementation: highlights of a CardioVascular Clinical Trialists (CVCT) Workshop of the ESC Working Group on CardioVascular Pharmacology and Drug Therapy.

    Zannad, Faiez

    2011-11-03

    This paper presents a summary of the potential practical and economic barriers to implementation of primary prevention of cardiovascular disease guided by total cardiovascular risk estimations in the general population. It also reviews various possible solutions to overcome these barriers. The report is based on discussion among experts in the area at a special CardioVascular Clinical Trialists workshop organized by the European Society of Cardiology Working Group on Cardiovascular Pharmacology and Drug Therapy that took place in September 2009. It includes a review of the evidence in favour of the \\'treat-to-target\\' paradigm, as well as potential difficulties with this approach, including the multiple pathological processes present in high-risk patients that may not be adequately addressed by this strategy. The risk-guided therapy approach requires careful definitions of cardiovascular risk and consideration of clinical endpoints as well as the differences between trial and \\'real-world\\' populations. Cost-effectiveness presents another issue in scenarios of finite healthcare resources, as does the difficulty of documenting guideline uptake and effectiveness in the primary care setting, where early modification of risk factors may be more beneficial than later attempts to manage established disease. The key to guideline implementation is to improve the quality of risk assessment and demonstrate the association between risk factors, intervention, and reduced event rates. In the future, this may be made possible by means of automated data entry and various other measures. In conclusion, opportunities exist to increase guideline implementation in the primary care setting, with potential benefits for both the general population and healthcare resources.

    We conducted a meta-analysis to summarise and quantify the effects of non-pharmacological interventions on sleep quality improvement in uraemic patients on dialysis. We defined the primary outcome as the change of sleep quality before and after interventions (evaluated by polysomonography or subjective questionnaires such as Pittsburgh sleep quality index, PSQI). The change of fatigue scales, inflammatory cytokines and adverse events were analysed as secondary outcomes. Twelve eligible randomised controlled trials and one prospective cohort study were identified. All three identified non-pharmacological interventions could result in a greater PSQI score reduction compared to controls: 1) cognitive-behavioural therapy (CBT) versus sleep hygiene education (standardised mean difference (SMD) 0.85, 95% CI 0.37-1.34); 2) physical training versus no training (SMD 3.36, 95% CI 2.16-4.57) and 3) Acupressure (including other acupoints massages) versus control (SMD 1.77, 95% CI 0.80-2.73). In terms of subscores, we found that CBT may shorten sleep latency, alleviate sleep disturbance and reduce the use of sleep medications. The finding of the cohort study suggested that intradialytic aerobic exercise training improved sleep quality in haemodialysis patients with restless leg syndrome. In conclusion, in dialysis-dependent patients, CBT could shorten sleep latency, alleviate sleep disturbance and reduce the use of sleep medications. Acupressure (including other acupoints massages) and exercise training are promising interventions but the results in these subgroups should be interpreted cautiously due to the concern of methodological quality and potential confounding factors.

    2016-01-01

    Knowledge about the history and development of therapeutic agents holds a central position in the education and training of pharmacists and pharmacologists. Students enjoy learning about the discovery of drugs, including details about the pioneer workers involved (apothecaries, organic chemists, pharmacologists, and physiologists) and the role played by serendipity. The treatment of people suffering from allergies and the development of drugs that block the actions of histamine at H1 and H2 receptors are the subject of this review. Pharmaceutical products that block H1 receptors are widely used as prophylactic treatment for seasonal allergies that plague millions of people worldwide. The development of H2 receptor antagonists revolutionized treatment of gastric hyperacidity, the principal cause of peptic ulcers. Antihistamine research has changed focus toward the development of drugs that block the action of histamine at H3 and H4 receptors and the therapeutic potential is gradually being appreciated.

    Full Text Available Cardiovascular diseases (CVDs are the leading cause of death and disability in the world. They have emerged as a major health threat in develop¬ing countries contrary to the prior belief that they were confined primarily to industrialized nations. The global burden of disease due to cardiovascular diseases is escalating, principally due to a sharp rise in the developing countries which are experiencing rapid health transition. An estimated 17.3 million people died from CVDs in 2008 and over 80% of CVD deaths take place in low and middle income countries. By 2030, almost 23.6 million people will die from CVDs. Therefore, finding ways to reduce the mortality of cardiovascular disease remains an important public health goal. Traditional Medicines have been an integral part of the healthcare system since time immemorial. WHO reports indicate that around eighty percent of the global population still relies on botanical drugs and several herbal medicines have advanced to clinical use in modern times. Unani occupies an important place in the rich traditional heritage of indigenous systems of medicine in India and contributes significantly to the health care. The core of treatment in Unani System of Medicine is based on drugs of herbal, mineral and animal origin. The ancient classical literature of Unani has mention of numerous drugs possessing cardioprotective and cardiotonic activity, Arjun (Terminalia arjuna and Zafran (Crocus sativus are two of them. The Unani physicians have been using these drugs successfully since ages and this is possible only by inherent quality and safety standards specified in the system.With the advent of new techniques and recent upsurge towards scientific exploration of traditional medicines, empirical data substantiating their safety and efficacy has been generated and had led to better understanding of their role to prevent and cure diseases. The aim of this paper is to review and highlight the work done on Arjun

    It is common for patients who are faced with physical or psychological suffering, particularly those in the advanced stages of a disease, to have some kind of wish to hasten death (WTHD). This paper reviews and summarises the current state of knowledge about the WTHD among people with end-stage disease, doing so from a clinical perspective and on the basis of published clinical research. Studies were identified through a search strategy applied to the main scientific databases. Clinical studies show that the WTHD has a multi-factor aetiology. The literature review suggests-perhaps in line with better management of physical pain-that psychological and spiritual aspects, including social factors, are the most important cause of such a wish. One of the difficulties facing clinical research is the lack of terminological and conceptual precision in defining the construct. Indeed, studies frequently blur the distinction between a generic wish to die, a WTDH (whether sporadic or persistent over time), the explicit expression of a wish to die, and a request for euthanasia or physician-assisted suicide. A notable contribution to knowledge in this field has been made by scales designed to evaluate the WTHD, although the problems of conceptual definition may once again limit the conclusions, which can be drawn from the results. Studies using qualitative methodology have also provided new information that can help in understanding such wishes. Further clinical research is needed to provide a complete understanding of this phenomenon and to foster the development of suitable care plans. PMID:20821377

    Tauch, Andreas; Fernández-Natal, Isabel; Soriano, Francisco

    2016-07-01

    The genus Corynebacterium represents a taxon of Gram-positive bacteria with a high G+C content in the genomic DNA. Corynebacterium kroppenstedtii is an unusual member of this taxon as it lacks the characteristic mycolic acids in the cell envelope. Genome sequence analysis of the C. kroppenstedtii type strain has revealed a lipophilic (lipid-requiring) lifestyle and a remarkable repertoire of carbohydrate uptake and utilization systems. Clinical isolates of C. kroppenstedtii have been obtained almost exclusively from female patients and mainly from breast abscesses and cases of granulomatous mastitis. However, the role of C. kroppenstedtii in breast pathologies remains unclear. This review provides a comprehensive overview of the taxonomy, microbiology, and microbiological identification of C. kroppenstedtii, including polyphasic phenotypic approaches, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, and the use of 16S rRNA gene sequencing. A clinical review presents reported cases, various antimicrobial treatments, antibiotic susceptibility assays, and antibiotic resistance genes detected during genome sequencing. C. kroppenstedtii must be considered a potential opportunistic human pathogen and should be identified accurately in clinical laboratories. PMID:27155209

    2016-08-16

    Posterior cortical atrophy (PCA) is a rare neurodegenerative condition characterized by progressive visual-perceptual deficits. Although the neurocognitive profile of PCA is a growing and relatively well-established field, non-pharmacological care remains understudied and to be widely established in clinical practice. In the present work we review the available literature on non-pharmacological approaches for PCA, such as cognitive rehabilitation including individual cognitive exercises and compensatory techniques to improve autonomy in daily life, and psycho-education aiming to inform people with PCA about the nature of their visual deficits and limits of cognitive rehabilitation. The reviewed studies represented a total of 7 patients. There is a scarcity of the number of studies, and mostly consisting of case studies. Results suggest non-pharmacological intervention to be a potentially beneficial approach for the partial compensation of deficits, improvement of daily functionality and improvement of quality of life. Clinical implications and future directions are also highlighted for the advancement of the field, in order to clarify the possible role of non-pharmacological interventions, and its extent, in PCA.

  16. Adenomyosis: A Clinical Review of a Challenging Gynecologic Condition.

    Struble, Jennifer; Reid, Shannon; Bedaiwy, Mohamed A

    2016-02-01

    Adenomyosis is a heterogenous gynecologic condition. Patients with adenomyosis can have a range of clinical presentations. The most common presentation of adenomyosis is heavy menstrual bleeding and dysmenorrhea; however, patients can also be asymptomatic. Currently, there are no standard diagnostic imaging criteria, and choosing the optimal treatment for patients is challenging. Women with adenomyosis often have other associated gynecologic conditions such as endometriosis or leiomyomas, therefore making the diagnosis and evaluating response to treatment challenging. The objective of this review was to highlight current clinical information regarding the epidemiology, risk factors, pathogenesis, clinical manifestations, diagnosis, imaging findings, and treatment of adenomyosis. Several studies support the theory that adenomyosis results from invasion of the endometrium into the myometrium, causing alterations in the junctional zone. These changes are commonly seen on imaging studies such as transvaginal ultrasound (TVUS) and magnetic resonance imaging (MRI). The second most common theory is that adenomyosis results from embryologic-misplaced pluripotent mullerian remnants. Traditionally, adenomyosis was only diagnosed after hysterectomy; however, studies have shown that a diagnosis can be made with biopsies at hysteroscopy and laparoscopy. Noninvasive imaging can be used to help guide the differential diagnosis. The most common findings on 2-dimensional/3-dimensional TVUS and MRI are reviewed. Two-dimensional TVUS and MRI have a respectable sensitivity and specificity; however, recent studies indicate that 3-dimensional TVUS is superior to 2-dimensional TVUS for the diagnosis of adenomyosis and may allow for the diagnosis of early-stage disease. Management options for adenomyosis, both medical and surgical, are reviewed. Currently, the only definitive management option for patients is hysterectomy. PMID:26427702

    Plasmodium falciparum is responsible for severe malaria which is one of the most prevalent and deadly infectious diseases in the world. The antimalarial therapeutic arsenal is hampered by the onset of resistance to all known pharmacological classes of compounds, so new drugs with novel mechanisms of action are critically needed. Albitiazolium is a clinical antimalarial candidate from a series of choline analogs designed to inhibit plasmodial phospholipid metabolism. Here we developed an original chemical proteomic approach to identify parasite proteins targeted by albitiazolium during their native interaction in living parasites. We designed a bifunctional albitiazolium-derived compound (photoactivable and clickable) to covalently crosslink drug-interacting parasite proteins in situ followed by their isolation via click chemistry reactions. Mass spectrometry analysis of drug-interacting proteins and subsequent clustering on gene ontology terms revealed parasite proteins involved in lipid metabolic activities and, interestingly, also in lipid binding, transport, and vesicular transport functions. In accordance with this, the albitiazolium-derivative was localized in the endoplasmic reticulum and trans-Golgi network of P. falciparum. Importantly, during competitive assays with albitiazolium, the binding of choline/ethanolamine phosphotransferase (the enzyme involved in the last step of phosphatidylcholine synthesis) was substantially displaced, thus confirming the efficiency of this strategy for searching albitiazolium targets.

    2008-01-01

    Full Text Available Hyperosmotic-hyperoncotic solutions have been widely used during prehospital care of trauma patients and have shown positive hemodynamic effects. Recently, there has been a growing interest in intra-operative use of hypertonic solutions. We reviewed 30 clinical studies on the use of hypertonic saline solutions during surgeries, with the majority being cardiac surgeries. Reduced positive fluid balance, increased cardiac index, and decreased systemic vascular resistance were the main beneficial effects of using hypertonic solutions in this population. Well-designed clinical trials are highly needed, particularly in aortic aneurysm repair surgeries, where hypertonic solutions have shown many beneficial effects. Examining the immunomodulatory effects of hypertonic solutions should also be a priority in future studies.

    Full Text Available Dengue is an important global public health problem. The World Health Organization estimates that 2/5 of entire world population are in risk of dengue infection. Almost 50 millions cases occur annually, with at least 20 thousand deaths. The etiological agent of this acute febrile disease is a single-strand positive-sense RNA virus of Flavivirus genus. It is an arboviral disease transmitted by Aedes sp. mosquitoes (Aedes aegypti and A. albopictus. Most infected individuals present asymptomatic infection, but some may develop clinical signs. Therefore, a wide spectrum of illness can be observed, ranging from unapparent, mild disease, called dengue fever, to a severe and occasionally fatal dengue hemorrhagic fever/dengue shock syndrome. Currently, neurological manifestations related to dengue infections are increasingly been observed and appears as a challenge for medical practice. In this study the neurological complications of dengue infection will be reviewed, focusing a better understanding of the disease for the clinical practice.

    Full Text Available The endocannabinoid system has been shown to be associated with neurodegenerative diseases and dementia. We review the preclinical and clinical data on cannabinoids and four neurodegenerative diseases: Alzheimer’s disease (AD, Huntington’s disease (HD, Parkinson’s disease (PD and vascular dementia (VD. Numerous studies have demonstrated an involvement of the cannabinoid system in neurotransmission, neuropathology and neurobiology of dementias. In addition, several candidate compounds have demonstrated efficacy in vitro. However, some of the substances produced inconclusive results in vivo. Therefore, only few trials have aimed to replicate the effects seen in animal studies in patients. Indeed, the literature on cannabinoid administration in patients is scarce. While preclinical findings suggest causal treatment strategies involving cannabinoids, clinical trials have only assessed the suitability of cannabinoid receptor agonists, antagonists and cannabidiol for the symptomatic treatment of dementia. Further research is needed, including in vivo models of dementia and human studies.

    Frostbite is a thermal injury that can occur when temperatures drop low enough for tissue to freeze. On rewarming the tissues, an inflammatory process develops which is often associated with tissue loss. The extent of the tissue loss reflects the severity of the cold exposure and includes factors such as temperature, duration, wind chill, altitude, and systemic hypothermia. This review discusses the epidemiology, the pathophysiological processes involved, and the clinical management of frostbite injuries. Practical advice is given on both the field and hospital management and how to seek expert advice from remote situations. The review also discusses newer developments in frostbite treatment such as intra-vascular thrombolysis and adjunctive treatments such as the use of intravenous vasodilators. PMID:21465915

    2009-01-01

    While the overall incidence of pouchitis is low, extensive research continues at clinical and experimental levels in attempts to unravel its etiology. The ileal pouch and pouchitis together represent a unique in vivo opportunity to study mucosal adaptation and inflammation in depth. In the recent past, molecular data relating to pouchitis has significantly expanded. These data provide invaluable insight into intracellular and extracellular events that underpin mucosal adaptation and inflammation. Advances in classification, risk factor evaluation, and prevention have meant that a review of this data, as well as its relationship to our current understanding of pouchitis, is both timely and warranted. Therefore, the aim of this review is to summarize recent data in the context of the established literature.

    LMNA-related disorders are caused by mutations in the LMNA gene, which encodes for the nuclear envelope proteins, lamin A and C, via alternative splicing. Laminopathies are associated with a wide range of disease phenotypes, including neuromuscular, cardiac, metabolic disorders and premature aging syndromes. The most frequent diseases associated with mutations in the LMNA gene are characterized by skeletal and cardiac muscle involvement. This review will focus on genetics and clinical features of laminopathies affecting primarily skeletal muscle. Although only symptomatic treatment is available for these patients, many achievements have been made in clarifying the pathogenesis and improving the management of these diseases. PMID:27529282

    Hands-on healing and energy-based interventions have been found in cultures throughout history around the world. These complementary therapies, rooted in ancient Eastern healing practices, are becoming mainstream. Healing Touch, a biofield therapy that arose in the nursing field in the late 1980s, is used in a variety of settings (i.e., pain centers, surgical settings, and private practices) with reported benefits (i.e., decreased anxiety, pain, and depressive behaviors; increased relaxation and a sense of well-being). However, clinical trial data concerning the effectiveness of Healing Touch have not been evaluated using a systematic, evidence-based approach. Thus, this systematic review is aimed at critically evaluating the data from randomized clinical trials examining the clinical efficacy of Healing Touch as a supportive care modality for any medical condition.

    Methamphetamine (MA) is a highly addictive psychostimulant drug that principally affects the monoamine neurotransmitter systems of the brain and results in feelings of alertness, increased energy and euphoria. The drug is particularly popular with young adults, due to its wide availability, relatively low cost, and long duration of psychoactive effects. Extended use of MA is associated with many health problems that are not limited to the central nervous system, and contribute to increased morbidity and mortality in drug users. Numerous studies, using complementary techniques, have provided evidence that chronic MA use is associated with substantial neurotoxicity and cognitive impairment. These pathological effects of the drug, combined with the addictive properties of MA, contribute to a spectrum of psychosocial issues that include medical and legal problems, at-risk behaviors and high societal costs, such as public health consequences, loss of family support and housing instability. Treatment options include pharmacological, psychological or combination therapies. The present review summarizes the key findings in the literature spanning from molecular through to clinical effects. PMID:23273775

    Full Text Available AM Arisco, EK Brantly, SR KrausUniversity of Texas Health Science Center at San Antonio, Department of Urology, San Antonio, Texas, USAAbstract: Overactive bladder (OAB is a common condition which negatively impacts the quality of life of afflicted patients. This can result in alterations in social interactions at home, in the workplace and in the community, often leading to depression and poor self esteem as well as loss of productivity. Traditional mainstays of treatment include both behavioral therapy and pharmacotherapy. Oxybutynin immediate release (IR represents the first such medication approved by the FDA specifically for treatment of OAB in 1975. Nevertheless, bothersome side effects in addition to thrice daily dosing often led to treatment cessation which raised the question that patients may actually prefer to live with their OAB symptoms rather than incur side effects or complex dosing schemes. Pharmacological advances ultimately led to development of a long-acting formulation of oxybutynin in the form of oxybutynin extended release (ER with the hope that this drug would maintain efficacy while decreasing bothersome side effects and improve compliance with the convenience of once daily dosing regimen. This paper will review the major clinical studies involving oxybutynin ER as well as its role in different patient populations and potential concerns with its use.Keywords: overactive bladder, urinary urge incontinence, antimuscarinic, oxybutynin

    of human diseases arising from defects in mitochondrial ion and ROS homeostasis, energy production and morphology [1]. Parkinson´s Disease (PD) is a very good example of this important mitochondrial component on neurodegenerative diseases. Anuradha Yadav, Swati Agrawal, Shashi Kant Tiwari, and Rajnish K. Chaturvedi (CSIR-Indian Institute of Toxicology Research / Academy of Scientific and Innovative Research, India) [6] remark in their review the role of mitochondrial dysfunction in PD with special focus on the role of oxidative stress and bioenergetic deficits. These alterations may have their origin on pathogenic gene mutations in important genes such as DJ-1, -syn, parkin, PINK1 or LRRK2. These mutations, in turn, may cause defects in mitochondrial dynamics (key events like fission/fusion, biogenesis, trafficking in retrograde and anterograde directions, and mitophagy). This work reviews different strategies to enhance mitochondrial bioenergetics in order to ameliorate the neurodegenerative process, with an emphasis on clinical trials reports that indicate their potential. Among them creatine, Coenzyme Q10 and mitochondrial targeted antioxidants/peptides are reported to have the most remarkable effects in clinical trials. They highlight a dual effect of PGC-1α expression on PD prognosis. Whereas a modest expression of this transcriptional co-activator results in positive effects, a moderate to substantial overexpession may have deleterious consequences. As strategies to induce PGC-1α activation, these authors remark the possibility to activate Sirt1 with resveratrol, to use PPAR agonists such as pioglitazone, rosiglitazone, fenofibrate and bezafibrate. Other strategies include the triggering of Nrf2/antioxidant response element (ARE) pathway by triterpenoids (derivatives of oleanolic acid) or by Bacopa monniera, the enhancement of ATP production by carnitine and -lipoic acid. Mitochondrial dysfunctions are the prime source of neurodegenerative diseases and

    Full Text Available In combination with whole report and partial report tasks, the Theory of Visual Attention (TVA can be used to estimate individual differences in five basic attentional parameters: The visual processing speed, the storage capacity of visual short-term memory, the perceptual threshold, the efficiency of top-down selectivity, and the spatial bias of attentional weighting. TVA-based assessment has been used in about 30 studies to investigate attentional deficits in a range of neurological and psychiatric conditions: (a neglect and simultanagnosia, (b reading disturbances, (c aging and neurodegenerative diseases, and most recently (d neurodevelopmental disorders. The article introduces TVA based assessment, discusses its methodology and psychometric properties, and reviews the progress made in each of the four research fields. The empirical results demonstrate the general usefulness of TVA-based assessment for many types of clinical neuropsychological research. The method’s most important qualities are cognitive specificity and theoretical grounding, but it is also characterized by good reliability and sensitivity to minor deficits. The review concludes by pointing to promising new areas for clinical TVA-based research.

    2014-03-01

    Over 60 bromodomains belonging to proteins with very different functions have been identified in humans. Several of them interact with acetylated lysine residues, leading to the recruitment and stabilization of protein complexes. The bromodomain and extra-terminal domain (BET) proteins contain tandem bromodomains which bind to acetylated histones and are thereby implicated in a number of DNA-centered processes, including the regulation of gene expression. The recent identification of inhibitors of BET and non-BET bromodomains is one of the few examples in which effective blockade of a protein-protein interaction can be achieved with a small molecule. This has led to major strides in the understanding of the function of bromodomain-containing proteins and their involvement in diseases such as cancer and inflammation. Indeed, BET bromodomain inhibitors are now being clinically evaluated for the treatment of hematological tumors and have also been tested in clinical trials for the relatively rare BRD-NUT midline carcinoma. This review gives an overview of the newest developments in the field, with a focus on the biology of selected bromodomain proteins on the one hand, and on reported pharmacological inhibitors on the other, including recent examples from the patent literature.

  16. Proton therapy - A systematic review of clinical effectiveness

    International Nuclear Information System (INIS)

    Background and purpose: Proton therapy is an emerging treatment modality for cancer that may have distinct advantages over conventional radiotherapy. This relates to its ability to confine the high-dose treatment area to the tumour volume and thus minimizing radiation dose to surrounding normal tissue. Several proton facilities are currently operating or under planning world-wide - in the United States, Asia and Europe. Until now no systematic review assessing the clinical effectiveness of this treatment modality has been published. Materials and methods: A systematic review of published studies that investigated clinical efficacy of proton therapy of cancer. Results: We included 54 publications: 4 randomized controlled trials (RCTs) reported in 5 publications, 5 comparative studies and 44 case series. Two RCTs addressed proton irradiation as a boost following conventional radiation therapy for prostate cancer, where one demonstrated improved biochemical local control for the highest dose group without increased serious complication rates. Proton therapy has been used to treat a large number of patients with ocular tumours, but except for one low quality RCT, no proper comparison with other treatment alternatives has been undertaken. Proton therapy offers the option to deliver higher radiation doses and/or better confinement of the treatment of intracranial tumours in children and adults, but reported studies are heterogeneous in design and do not allow for strict conclusions. Conclusion: The evidence on clinical efficacy of proton therapy relies to a large extent on non-controlled studies, and thus is associated with low level of evidence according to standard heath technology assessment and evidence based medicine criteria

  17. Clinical outcomes resulting from telemedicine interventions: a systematic review

    Full Text Available Abstract Background The use of telemedicine is growing, but its efficacy for achieving comparable or improved clinical outcomes has not been established in many medical specialties. The objective of this systematic review was to evaluate the efficacy of telemedicine interventions for health outcomes in two classes of application: home-based and office/hospital-based. Methods Data sources for the study included deports of studies from the MEDLINE, EMBASE, CINAHL, and HealthSTAR databases; searching of bibliographies of review and other articles; and consultation of printed resources as well as investigators in the field. We included studies that were relevant to at least one of the two classes of telemedicine and addressed the assessment of efficacy for clinical outcomes with data of reported results. We excluded studies where the service did not historically require face-to-face encounters (e.g., radiology or pathology diagnosis. All included articles were abstracted and graded for quality and direction of the evidence. Results A total of 25 articles met inclusion criteria and were assessed. The strongest evidence for the efficacy of telemedicine in clinical outcomes comes from home-based telemedicine in the areas of chronic disease management, hypertension, and AIDS. The value of home glucose monitoring in diabetes mellitus is conflicting. There is also reasonable evidence that telemedicine is comparable to face-to-face care in emergency medicine and is beneficial in surgical and neonatal intensive care units as well as patient transfer in neurosurgery. Conclusions Despite the widespread use of telemedicine in virtually all major areas of health care, evidence concerning the benefits of its use exists in only a small number of them. Further randomized controlled trials must be done to determine where its use is most effective.

    Full Text Available Diabetes mellitus is a public health problem which leads to serious complications over time. Experimentally, many herbs have been recommended for treating diabetes. In most cases, however, the recommendations are based on animal studies and limited pieces of evidence exist about their clinical usefulness. This review focused on the herbs, the hypoglycemic actions of which have been supported by three or more clinical studies. The search was done in Google Scholar, Medline and Science Direct databases using the key terms diabetes, plants, herbs, glucose and patients. According to the clinical studies, Aegle marmelos, Allium cepa, Gymnema sylvestre, Momordica charantia, Ocimum sanctum, Nigella sativa, Ocimum sanctum, Panax quinquefolius, Salacia reticulate, Silybum marianum and Trigonella foenum-graecum have shown hypoglycemic and, in some cases, hypolipidemic activities in diabetic patients. Among them, Gymnema sylvestre, Momordica charantia, Silybum marianum and Trigonella foenum-graecum have acquired enough reputation for managing diabetes. Thus, it seems that physicians can rely on these herbs and advise for the patients to improve management of diabetes.

    2010-12-01

    Full Text Available Stealth liposomes are long-circulating liposomes with inclusion of the synthetic polymer poly-(ethylene glycol (PEG in liposome composition. The presence of PEG on the surface of the liposomal carrier has been shown to extend bloodcirculation time while reducing mononuclear phagocyte system uptake. Further these liposomes exhibit increasing drug stability and solubility, lowering toxicity, increasing half-life, decreasing clearance and immunogenicity. Sterically stabilized vesicles can act either as long circulating micro reservoirs or tumour (or site of inflammation and infection targeting vehicles. The former applications require larger liposomes (0.2µm while the latter one is due to the ability of small vesicles to leave the blood circulation. The altered biodistribution of stealth liposomes, in addition to the accumulation at the sites characterised with porous blood capillaries, such as in tumors, inflammations, and infections. A pharmacogenomic approach for delivery of siRNA to cells is the use of liposomes as targeted delivery vehicles. Stealth technology summarizes pre-clinical and clinical data relating to the principal liposome formulations, encapsulating active molecules, with high target efficiency and activity. Further these liposomes offer improvements in bioreclamation and various monitoring and analytical-diagnostic applications. The paper reviews the clinical aspects of these liposomes with longer therapeutic half lives in diseases like Reconstitution of membrane proteins into artificial membranes, model biological membranes, cell function, fusion, recognition , pharmaceutics studies of drug action , medicine drug-delivery and medical diagnostics, gene therapy and there extensive use in the pharmaceutical industry.
