  12. Clinical pharmacology of homoharringtonine

    Energy Technology Data Exchange (ETDEWEB)

    Savaraj, N.; Lu, K.; Dimery, I.; Feun, L.G.; Burgess, M.; Keating, M.; Loo, T.L.

    1986-12-01

    Clinical pharmacokinetics of homoharringtonine (HHT) were studied in eight patients who received uniformly labeled HHT at 3-4 mg/m2 (150 mu Ci) by continuous 6-hour infusion. The drug and metabolites were quantified by radiochemical and high-performance liquid chromatographic techniques. Computerized nonlinear least-square regression and curve stripping were used to characterize HHT and total (/sup 3/H)HHT equivalent pharmacokinetics. Unchanged HHT in the plasma declined biphasically, with an alpha-half-life of 0.5 +/- 0.1 hours and a beta-half-life of 9.3 +/- 1.4 hours. The total clearance of HHT was 177.4 +/- 27.7 ml X hour-1 X kg-1, and the apparent volume of distribution, estimated from the area under the drug concentration versus time curve, was 2.4 +/- 0.4 L X kg-1. Correspondingly, the total (/sup 3/H)HHT equivalent disappeared from the plasma in a triphasic manner. Compared with the pharmacokinetic parameters of unchanged HHT, the terminal half-life of total /sup 3/H was 67.5 +/- 7.5 hours, 7.4 times longer; the total clearance was 30.9 +/- 3.1 ml X hour-1 X kg-1, 5.5 times slower; but the volume of distribution by area was 2.7 +/- 0.1 L X kg-1, nearly the same. The 72-hour cumulative urinary excretion of total tritium was 28.2% of the administered dose and only 38.3% of this resided in unchanged HHT. Thus, urinary excretion was not a major route of elimination of HHT. Moreover, HHT underwent extensive metabolism; one major and two minor unidentified products were detected in both plasma and urine.

  13. Clinical pharmacology and vascular risk.

    Science.gov (United States)

    Silvestrelli, G; Corea, F; Micheli, S; Lanari, A

    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

    Karim, S M; Hillier, K

    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

    Full Text Available Christopher S Beevers¹, Shile Huang²¹Department of Pharmacology, Ross University School of Medicine, Picard-Portsmouth, Commonwealth of Dominica; ²Department of Biochemistry and Molecular Biology, Louisiana State University Health Sciences Center, Shreveport, LA, USAAbstract: The polyphenol natural product curcumin has been the subject of numerous studies over the past decades, which have identified and characterized the compound's pharmacokinetic, pharmacodynamic, and clinical pharmacological properties. 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

  18. Angioedema: Clinical Presentations and Pharmacological Management.

    Science.gov (United States)

    Collins-Yoder, Angela Smith

    2016-01-01

    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

  1. Radioimmunoassay in basic and clinical pharmacology

    Energy Technology Data Exchange (ETDEWEB)

    Patrono, C.; Peskar, B.A.

    1987-01-01

    The subject of the book is the development, validation and application of radioimmunoassay (RIA) techniques for the measurement of a variety of substances in animal and human body fluids. The book discusses methodological and conceptual issues related to the main classes of mediators of drug action and to drugs themselves, as assayed by this particular analytical technique. A number of introductory chapters provide basic information concerning production and characterization of antibodies, labeling techniques, statistical aspects and validation criteria, insight into problems related to the development and validation of RIA for the newly discovered mediator(s). In the following chapters, the emphasis is placed on the technical details relevant to each class of compounds and on specific aspects of their applications to basic and/or clinical pharmacological studies. New developments in this area, such as monoclonal antibodies and non-radioactive labeling techniques, are also covered.

  2. Chlorhexidine--pharmacology and clinical applications.

    Science.gov (United States)

    Lim, K-S; Kam, P C A

    2008-07-01

    Chlorhexidine is a widely used skin antisepsis preparation and is an ingredient in toothpaste and mouthwash. It is an especially effective antiseptic when combined with alcohol. Its antimicrobial effects persist because it is binds strongly to proteins in the skin and mucosa, making it an effective antiseptic ingredient for handwashing, skin preparation for surgery and the placement of intravascular access. Catheters impregnated with chlorhexidine and antimicrobial agents can reduce the incidence of catheter-related bloodstream infections. Contact dermatitis related to chlorhexidine is not common in health care workers. The incidence of contact dermatitis to chlorhexidine in atopic patients is approximately 2.5 to 5.4%. Acute hypersensitivity reactions to chlorhexidine are often not recognised and therefore may be underreported. This review discusses the pharmacology, microbiology, clinical applications and adverse effects of chlorhexidine.

    Fong, K.L.L.; Ho, D.H.W.; Benjamin, R.S.; Brown, N.S.; Bedikian, A.; Yap, B.S.; Wiseman, C.L.; Bodey, G.P.; Kramer W.

    1982-01-01

    During the phase Y clinical trial of a new antitumor agent, bruceantin, the pharmacology was studied in 18 cancer patients. The drug was infused i.v. for 3 h at doses ranging from 1 to 3.6 mg/m/sup 2/ per for 5. The plasma drug disappearance curves were biphasic, with a fast initial half-life of less than 15 min. The second half-life varied from 0.7 to 38 h among different patients and was not dose-related. The difference between the tsub(1/2..beta..) on day 1 and that on day 5 was not significant. In patients with normal liver function, the mean plasma concentration at the end of infusion was 22 ng/ml, and the value of the area under the concentration x time curve (AUC) was 111 (ng/ml)h. In contrast, in patients with abnormal liver function the corresponding values were 115 ng/ml and 830 (ng/ml)h, respectively. In addition, these patients had a slower elimination half-life of 10.9 h and a decreased total clearance of 157 ml/min/m/sup 2/, as compared with 2.6 h and 671 ml/min/m/sup 2/, respectively, for the normal group. All these differences were statistically significant. Patients with abnormal liver function developed more severe toxicity, including fever, severe nausea, vomiting, and hypotension. Two patients with severe hepatic dysfunction received a reduced dose and developed no toxicity. These results demonstrated the importance of the effects of liver dysfunction on drug disposition and showed that the dosage should be reduced in patients with hepatic dysfunction.

    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.

    2013-12-01

    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.

    Full Text Available Clinical pharmacologists undertake many tasks, and this makes defining a curriculum challenging. This is especially so under the changing circumstances in developing countries, where clinical pharmacology has an expanding role. The clinical pharmacologist may be responsible for conducting ethical clinical trials, supporting the needs of the generic drug industry, providing access to safe, effective and affordable medicines, guiding their rational use, achieving millennium development goals, and supervising medicines management standards for hospital accreditation. Clinical pharmacologists, including those in developing countries, have a great opportunity to contribute to public health and the growth of pharmaceutical industry, but at present, less clinical research is undertaken and fewer clinical trials are done than might be expected. Here we review clinical pharmacology training in India, consider the needs of different professionals contributing to clinical research and medicines utilization, and suggest ways in which current programs can be modified and new programs started. The conclusions are relevant to clinical pharmacology in both the developing and the developed world.

    Science.gov (United States)

    Kittel, Anja; Maas, Renke

    2014-01-01

    The methylarginines asymmetric dimethylarginine (ADMA) and monomethylarginine (L-NMMA) are endogenously formed inhibitors of nitric oxide synthases (NOS), which have extensively been investigated as risk markers and used as pharmacological tools to study the L-arginine-nitric oxide (NO) pathway in vitro and in vivo. It is the aim of the present review to summarize the clinical and experimental data on the pharmacological properties that are of relevance when planning and conducting experiments and clinical studies involving methylarginines. Key pharmacodynamic and pharmacokinetic data including IC50 values of ADMA and L-NMMA for NOS isoforms and transport proteins, as well as metabolism by dimethylarginine dimethylaminohydrolases (DDAH1 and DDAH2) and alanine-glyoxylate aminotransferase 2 (AGXT2) are discussed.

  19. Topical corticosteroids: clinical pharmacology and therapeutic use.

    Science.gov (United States)

    Miller, J A; Munro, D D

    1980-02-01

    The development of topical corticosteroids has enabled many dermatoses to be more effectively treated than previously, but there is also no doubt that misuse of these preparations can lead to troublesome local effects and potentially serious systemic problems. The most effective assay for comparing different compounds has been their vasoconstrictive activity, and this on the whole correlates well with clinical effect. To be effective, corticosteroid must be absorbed and the importance of concentration, occlusion, the type of vehicle, added penetrants such as urea and the anatomical site, on the amount of absorption and therefore on clinical activity has been demonstrated. Ointments have been shown to be more effective than creams but because of the considerable choice of potencies now available most dermatologists tend to prescribe the different formulations according to the wishes of the patient. For the same reason, dilution of the commercially marketed preparations is now not generally recommended. The main therapeutic activity of topical corticosteroids is their nonspecific anti-inflammatory effect, thought to be primarily a result of their action on the chemical mediators of inflammation. They have also been shown to be antimitotic which may well be relevant not only to the treatment of scaling dermatoses but also to their dermal thinning effect resulting from inhibition of fibroblasts. Combinations of corticosteroids with antibacterial and antifungal agents have been shown to be very effective in flexural eruptions and secondarily infected dermatoses. As a general rule, the use of topical corticosteroids in outpatients, unless badly misused, is not associated with any significant risk of adrenal axis suppression, but care must be exercised as to the amount prescribed, especially if large areas of the body are to be treated with highly potent preparations. Certain groups such as young children and patients with liver failure, and certain anatomical sites such

    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

    Financial instruments, such as professional membership fees, are part of the science and technology policy toolkit for creating an environment conducive to developing an international health knowledge network. To minimize a hurdle to global knowledge exchange in clinical pharmacology, the American College of Clinical Pharmacology reevaluated fees for its international members. Secondary market research was conducted on salary data available from US-based multinational firms. Salary comparisons for the same position based in the United States and in a developing economy were used to generate an index ratio. Applying this ratio, a tiered-membership fee structure was constructed for the approximately 120 countries where gross national income meets the World Bank classification of "developing economy." The index ratio serves as a paradigm for structuring fees across a variety of programs. With the implementation of an adjusted dues structure, information and networks of colleagues are now more accessible to clinical pharmacologists in developing economies.

    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

    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.

    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.

  7. Considerations for clinical pharmacology studies for biologics in emerging markets.

    2015-03-01

    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

    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

    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 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

    A meta-analysis was carried out of clinical trials published between 1987 and 2001 in respect of the clinical pharmacology and safety as well as the diagnostic efficacy of gadolinium-DTPA (Gd-DTPA) for direct intra-articular injection before MRI examination.Design. Scientific papers (clinical, postmortem and experimental studies) and information from the manufacturer regarding intra-articular injection of Gd-DTPA that addressed questions of mode of action, optimal concentration and dose, elimination and safety were reviewed. Clinical studies were classified according to their study design. The sensitivity, specificity and accuracy of MR arthrography (MRA) were compared with a ''gold standard'' (arthroscopy, arthrotomy) and other radiological evidence for different joints.Results. Fifty-two clinical studies of the overall 112 studies addressed aspects of diagnostic efficacy of MRA in patients or in healthy volunteers. The shoulder was the most assessed joint (29 of 52 studies). Good (>80%) or even excellent (90-100%) sensitivity, specificity and accuracy were found for MRA in most indications, especially for the shoulder and knee joints and induced extension of rotator cuff lesions, labrum abnormalities and postoperative meniscal tears. Two millimoles per liter has proven to be the best concentration for intra-articular administration of Gd-DTPA. After passive complete diffusion from the joint within 6-24 h, complete and rapid renal elimination takes place after intra-articular injection. Local safety proved to be excellent after intra-articular administration of Gd-DTPA. Regarding systemic tolerance almost no side effects have been reported, but the same safety considerations apply for intra-articular administration of Gd-DTPA as for intravenous injection.Conclusions. The diagnostic efficacy of intra-articular MRA in most clinical conditions affecting major joints is greater than that of plain MRI. In some diagnostic problems MRA achieves almost

    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.

    2015-06-01

    Fentanyl is a synthetic opioid that is very important in anesthetic practice because of its relatively short time to peak analgesic effect and the rapid termination of action after small bolus doses. The objective of this survey is to review the clinical pharmacology of fentanyl in preterm infants. The bibliographic search was performed using PubMed and EMBASE databases as search engines. In addition, the books Neofax: A manual of drugs used in neonatal care and Neonatal formulary were consulted. Fentanyl is N-dealkylated by CYP3A4 into the inactive norfentanyl. Fentanyl may be administered as bolus doses or as a continuous infusion. In neonates, there is a remarkable interindividual variability in the kinetic parameters. In neonates, fentanyl half-life ranges from 317 minutes to 1266 minutes and in adults it is 222 minutes. Respiratory depression occurs when fentanyl doses are >5 μg/kg. Chest wall rigidity may occur in neonates and occasionally is associated with laryngospasm. Tolerance to fentanyl may develop after prolonged use of this drug. Significant withdrawal symptoms have been reported in infants treated with continuous infusion for 5 days or longer. Fentanyl is an extremely potent analgesic and is the opioid analgesic most frequently used in the neonatal intensive care unit.

    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.

  1. Prevention and treatment of traveler's diarrhea: a clinical pharmacological approach.

    Scarpignato, C; Rampal, P

    1995-01-01

    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.

    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

    2013-02-01

    Cannabis, or marijuana, has been used for medicinal purposes for many years. Several types of cannabinoid medicines are available in the United States and Canada. Dronabinol (schedule III), nabilone (schedule II), and nabiximols (not U.S. Food and Drug Administration approved) are cannabis-derived pharmaceuticals. Medical cannabis or medical marijuana, a leafy plant cultivated for the production of its leaves and flowering tops, is a schedule I drug, but patients obtain it through cannabis dispensaries and statewide programs. The effect that cannabinoid compounds have on the cannabinoid receptors (CB(1) and CB(2) ) found in the brain can create varying pharmacologic responses based on formulation and patient characteristics. The cannabinoid Δ(9) -tetrahydrocannabinol has been determined to have the primary psychoactive effects; the effects of several other key cannabinoid compounds have yet to be fully elucidated. Dronabinol and nabilone are indicated for the treatment of nausea and vomiting associated with cancer chemotherapy and of anorexia associated with weight loss in patients with acquired immune deficiency syndrome. However, pain and muscle spasms are the most common reasons that medical cannabis is being recommended. Studies of medical cannabis show significant improvement in various types of pain and muscle spasticity. Reported adverse effects are typically not serious, with the most common being dizziness. Safety concerns regarding cannabis include the increased risk of developing schizophrenia with adolescent use, impairments in memory and cognition, accidental pediatric ingestions, and lack of safety packaging for medical cannabis formulations. This article will describe the pharmacology of cannabis, effects of various dosage formulations, therapeutics benefits and risks of cannabis for pain and muscle spasm, and safety concerns of medical cannabis use.

    Clinical pharmacology is an essential consideration in chronic therapies, and may play a significant role in modifying the pharmacological characteristics of drug formulations. Improvement in drug formulations may ensure their safe and effective use over a period of time. This has been particularly observed with α-1 adrenergic blockers in hypertension management. Advancements in formulations like prazosin GITS, have resulted in improvement in tolerability profile and smoother, more effective blood pressure control, which reasonably translate into improvement in patient compliance and better clinical outcomes.

    2005-01-01

    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.

    Full Text Available This article presents the results of the studies of the influence of a new complex hepatoprotective preparation on the basic system of the body, the mechanism of occurrence and manifestation of its biological effects, the dependence of this action from the components that are parts of the preparation, the dose, as well as the regularity of manifestation of possible side effects. The effect of the different doses of the preparation (1% and 2% on the average daily weight gain and morphological and biochemical indices of the birds’ blood was studied. The conducted research determined a stimulatory influence of the preparation on the growth, development and safety of broiler chickens. The new hepatoprotector exhibits the properties aimed on revitalizing the erythro- and hematopoiesis and magnification of the cellular immunity against the exogenous influence. The use of the preparation helps to improve liver function and reduce the toxic load on hepatocytes, which manifests an increase in a number of metabolic parameters, such as total protein, glucose, calcium, phosphorus. We have noted an expressed hepatoprotective effect on the enzyme activity of AST and the remission of the cytolytic syndrome of the experimental chickens. Thereby it was found out that the complex hepatoprotective preparation has a pronounced pharmacological activity, providing a significant impact on the energy of the broiler chickens’ growth and their safety, morphological and biochemical indices of the blood and metabolic processes in the body of the bird

    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

    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.

    of comparable or superior efficacy and side-effect profiles to existing APDs; (2) development of novel (and presumably non-D(2)) mechanism APDs; (3) development of compounds to be used as adjuncts to APDs to augment efficacy by targeting specific symptom dimensions of schizophrenia and particularly those not responsive to traditional APD treatment. In addition, efforts are being made to determine if the products of susceptibility genes in schizophrenia, identified by genetic linkage and association studies, may be viable targets for drug development. Finally, a focus on early detection and early intervention aimed at halting or reversing progressive pathophysiological processes in schizophrenia has gained great influence. This has encouraged future drug development and therapeutic strategies that are neuroprotective. This article provides an update and critical review of the pharmacology and clinical profiles of current APDs and drugs acting on novel targets with potential to be therapeutic agents in the future.

  14. Pharmacological basis and clinical evidence of dabigatran therapy

    Directory of Open Access Journals (Sweden)

    Redondo Santiago

    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.

    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.

    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.

    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

    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

    Berberine is a quaternary ammonium salt from the protoberberine group of isoquinoline alkaloids found in such plants as gender Berberis. Berberine is recognised to improve glucose and lipid metabolism disorders and preliminary clinical evidences suggest the ability of berberine to reduce endothelial inflammation improving vascular health, even in patients already affected by cardiovascular diseases, suggesting a possible interesting role of berberine and its metabolites in clinical practice. However, its physicochemical properties, pharmacokinetic, and metabolism are not fully elucidated and contradictory data have been reported. This review provides a summary regarding the pharmacological and biological features of berberine, with a focus on berberine as well as their pharmacologically active metabolites and the different mechanisms underlying their activities in order to clarify the correct use of berberine supplementation, alone or in association with other nutraceuticals, for the management of metabolic disorders associated to increased cardiovascular disease risk. A particular attention has also been given to the available clinical trials assessing its short- and middle- term use tolerability, safety and efficacy in various conditions, such as dyslipidaemia, impaired fasting glucose, metabolic syndrome and type 2 diabetes.

    Allosteric interactions play vital roles in metabolic processes and signal transduction and, more recently, have become the focus of numerous pharmacological studies because of the potential for discovering more target-selective chemical probes and therapeutic agents. In addition to classic early studies on enzymes, there are now examples of small molecule allosteric modulators for all superfamilies of receptors encoded by the genome, including ligand- and voltage-gated ion channels, G protein-coupled receptors, nuclear hormone receptors, and receptor tyrosine kinases. As a consequence, a vast array of pharmacologic behaviors has been ascribed to allosteric ligands that can vary in a target-, ligand-, and cell-/tissue-dependent manner. The current article presents an overview of allostery as applied to receptor families and approaches for detecting and validating allosteric interactions and gives recommendations for the nomenclature of allosteric ligands and their properties.

    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.

    Full Text Available The use of animals as sources of medicines is a cross-cultural phenomenon that is historically ancient and geographically widespread. This article reviews the use of mollusks in traditional medicine and discusses the clinical and pharmacological importance of these invertebrates. The roles that mollusks play in folk practices related to the healing and/or prevention of illnesses have been recorded in different social-cultural contexts worldwide. The clinical and therapeutic use of compounds coming from different species of mollusks is recorded in the literature. The chemistry of natural products provided by oysters, mussels, clams, sluggards, and snails has been substantially investigated, but the majority of these studies have focused on the subclasses Opistobranchia and Prosobranchia. Research into the knowledge and practices of folk medicine makes possible a better understanding of the interaction between human beings and the environment, in addition to allowing the elaboration of suitable strategies for the conservation of natural resources.

    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.

    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.

    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.

    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.

    In order to determine the effect of client advisory board membership on clients' awareness of a clinic, and on client attitudes of independence, the responses of 13 board members were compared with those of 13 matched controls on two self-report measures (Clinic Recognition Test, Client Independence Questionnaire) before and after 3-month periods. Analysis of the results indicated that, whereas the responses of controls did not significantly change on the Client Independence Questionnaire, the responses of board members indicated a significant increase in attitudes of independence. And, even though both board members and control clients significantly increased their awareness of clinic and staff over 3 months, the awareness of the broad members was significantly greater than that of the control clients.

    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.

    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.

  17. A Humanized Clinically Calibrated Quantitative Systems Pharmacology Model for Hypokinetic Motor Symptoms in Parkinson's Disease.

    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

    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

    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.

    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.

    Objectives: To find out the impact of teaching clinical pharmacology and rational therapeutics (CPT) to medical undergraduates (UGs) and interns. Materials and Methods: This cross-sectional, prospective study was conducted on three UGs batches and interns using two pretested validated structured questionnaires, modified from the work of Tobaiqy et al. The study was approved by the Institutional Ethics Committee. ANOVA and Chi-square test were used for statistical analysis. The value of P < 0.05 was considered statistically significant. Results: A total of 379 UGs and 96 interns participated in this study. Mean knowledge score of interns was significantly reduced as compared to UGs (P < 0.0001). A significant increase in confidence for unsupervised prescribing of nonsteroidal anti-inflammatory drugs (99%), oral rehydration salt, iron salts was perceived among interns as compared to UGs (P < 0.05). However, 63.5% confessed problems in selection of drugs, drug–drug interactions, prescribing in special patient population. Although they were confident prescribing fixed dose combination for adult patients (89.5%), majority were hesitant to prescribe opioids (77%), steroids (76%), vaccines (75%), and antihypertensives (62%). Conclusion: The theoretical CPT teaching transfers knowledge to UGs; however, it is not retained in internship and does not adequately prepare interns to prescribe safe and rational drugs.

    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.

    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.

    Purpose Cariprazine is a potent dopamine D3-preferring D3/D2 receptor partial agonist in development for the treatment of schizophrenia, bipolar mania, and depression. Pharmacokinetics of cariprazine and the two clinically relevant metabolites (desmethyl- and didesmethyl-cariprazine) was evaluated in a clinical pharmacology study. Methods This was a multicenter, randomized, open-label, parallel-group, fixed-dose (3, 6, or 9 mg/day) study of 28-week duration (≤4-week observation, 12-week open-label treatment, and 12-week follow-up). Once-daily cariprazine was administered to 38 adult patients with schizophrenia. The pharmacokinetics of cariprazine, metabolites, and total active moieties (sum of cariprazine and two metabolites) was evaluated; efficacy and safety were also assessed. Results Steady state was reached within 1–2 weeks for cariprazine and desmethyl-cariprazine, 4 weeks for didesmethyl-cariprazine, and 3 weeks for total active moieties. Cariprazine and desmethyl-cariprazine levels decreased >90% within 1 week after the last dose, didesmethyl-cariprazine decreased ~50% at 1 week, and total active moieties decreased ~90% within 4 weeks. Terminal half-lives of cariprazine, desmethyl-cariprazine, and didesmethyl-cariprazine ranged from 31.6 to 68.4, 29.7 to 37.5, and 314 to 446 hours, respectively. Effective half-life (calculated from time to steady state) of total active moieties was ~1 week. Incidence of treatment-emergent adverse events was 97.4%; 15.8% of patients discontinued due to adverse events. No abnormal laboratory values or major differences from baseline in extrapyramidal symptoms were observed. Conclusion Cariprazine and its active metabolites reached steady state within 4 weeks, and exposure was dose proportional over the range of 3–9 mg/day. Once-daily cariprazine was generally well tolerated in adult patients with schizophrenia. PMID:26834462

    2016-08-01

    The dose of acetylsalicylic acid (ASA) commonly used in the prevention and treatment of arteriosclerotic angiopathies is equal to or less than 100 mg daily. This choice of dose is predominantly based on molecular-pharmacological findings showing an inhibition in synthesis of the prothrombotic thromboxane (TXB2) and an irreversible inhibition in blood platelet aggregation. However, an analysis of ASA dose-effect relationships for doses of 50 - 500 mg (PO and IV) shows that doses of ASA up to 100 mg daily produce only a small or moderate inhibition in collagen/epinephrine-induced platelet aggregation and have no significant effect on the important platelet factors, PF3 and PF4. Doses of ASA 300 - 500 mg, on the other hand, inhibit platelet aggregation almost completely and, in addition, produce a 50 - 70% inhibition in PF3 and PF4 lasting at least 24 hours. There is also evidence that doses of ASA above 100 mg daily markedly inhibit thromboxane synthesis for up to 24 hours and that doses of 500 mg daily produce a clinically relevant inhibition in platelet adhesion to vessel walls for up 72 hours and prevent procoagulatory shape changes for up to 12 hours. These findings suggest that a dose of ≥ 300 mg at intervals of 2 - 3 days would be more appropriate for primary and secondary prophylaxis of arteriosclerotic angiopathies and that the benefit-risk ratio would be greater because of the increased availability of mucoprotective prostaglandins, PGI2 (prostacyclin) and the gastroprotective, PGE2. Our viewpoint, predominantly based on findings with biomarkers, could serve as a basis for further randomized controlled studies.

    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

    Paclitaxel, an effective antitumor agent, is formulated in various vehicles serving as carriers to deliver the hydrophobic paclitaxel to tissue. The approved formulations in the U.S. are paclitaxel formulated in Cremophor EL (currently known as Kolliphor EL) and nanoparticle albumin-bound paclitaxel (nab-paclitaxel). Despite having the same active ingredient (paclitaxel), different formulations produce distinct products with unique efficacy and safety profiles. A semimechanistic model was developed to describe the pharmacologic sensitivity of paclitaxel under different formulations. Circulating paclitaxel concentration data from patients treated with nab-paclitaxel or Cremophor EL-paclitaxel were analyzed in NONMEM using a semimechanistic model with simultaneous disposition of paclitaxel-carrier complexes and the total paclitaxel released from the complexes. The key factors driving paclitaxel exposure in circulation and peripheral tissues were explored via sensitivity analysis. The rapid decline of total paclitaxel concentration following intravenous administration of nab-paclitaxel and Cremophor EL-paclitaxel was attributed to rapid tissue distribution of the paclitaxel-carrier complexes, with minor contribution of free and protein-bound paclitaxel. Distribution of nab-paclitaxel to peripheral tissue was 4-fold faster and 10-fold more extensive than that of Cremophor EL-paclitaxel micelles, resulting in distinct tissue paclitaxel profiles. Sensitivity analyses showed the plasma paclitaxel-time profile was insensitive to the rapid rates of tissue distribution and decomposition of paclitaxel-carrier complexes but that the tissue distribution profile of paclitaxel was highly sensitive. Tissue distribution of paclitaxel is carrier complex system-dependent. Different delivery systems result in distinct tissue paclitaxel profiles but similar paclitaxel concentration-time profiles in plasma or blood, rendering the paclitaxel plasma profile a poor surrogate for its

    2007-01-01

    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

    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

    Benzodiazepines are widely used to treat anxiety and insomnia in elderly patients. The interest of this prescription is discussed in this article. The discussion is based on the pharmacological properties and adverse effects of benzodiazepines in the elderly subjects. The conclusions are that benzodiazepines should be rarely prescribed in elderly people; many patients treated by benzodiazepines should be withdrawn and other therapeutic strategies than benzodiazepines should be considered to treat anxiety and insomnia in the elderly patients.

    Traditional Chinese medicine (TCM) has been used to treat tumors for years and has been demonstrated to be effective. However, the underlying molecular mechanisms of herbs remain unclear. This study aims to ascertain molecular targets of herbs prolonging survival time of patients with advanced hepatocellular carcinoma (HCC) based on network pharmacology, and to establish a research method for accurate treatment of TCM. The survival benefit of TCM treatment with Chinese herbal medicine (CHM) was proved by Kaplan–Meier method and Cox regression analysis among 288 patients. The correlation between herbs and survival time was performed by bivariate correlation analysis. Network pharmacology method was utilized to construct the active ingredient-target networks of herbs that were responsible for the beneficial effects against HCC. Cox regression analysis showed CHM was an independent favorable prognostic factor. The median survival time was 13 months and the 5-year overall survival rates were 2.61% in the TCM group, while there were 6 months, 0 in the non-TCM group. Correlation analysis demonstrated that 8 herbs closely associated with prognosis. Network pharmacology analysis revealed that the 8 herbs regulated multiple HCC relative genes, among which the genes affected proliferation (KRAS, AKT2, MAPK), metastasis (SRC, MMP), angiogenesis (PTGS2) and apoptosis (CASP3) etc. PMID:27143508

    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.

    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

    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.

    The development and progression of symptomatic diabetic neuropathy (SDN) is linked to hyperglycemia. The effort to improve compensation of diabetes mellitus during therapy is therefore very important. This is where the cooperation between the diabetologist and neurologist within therapy plays an important role. The pharmaco-logical therapy of symptomatic sensitive peripheral diabetic neuropathy is difficult and with a less than satisfactory effect. A variety of active substances is used in symptomatic therapy, primarily designed for intervention in other pathological conditions. The recommended guidelines include antidepressants, anticonvulsants, opiates and their derivatives. However this therapy brings with it a relatively high incidence of adverse effects which detract from patients adherence to treatment. Very good results are reached by the therapy with thioctacid.

    Full Text Available Andrographis paniculata (Burm. F Nees, generally known as “king of bitters,” is an herbaceous plant in the family Acanthaceae. In China, India, Thailand, and Malaysia, this plant has been widely used for treating sore throat, flu, and upper respiratory tract infections. Andrographolide, a major bioactive chemical constituent of the plant, has shown anticancer potential in various investigations. Andrographolide and its derivatives have anti-inflammatory effects in experimental models asthma, stroke, and arthritis. In recent years, pharmaceutical chemists have synthesized numerous andrographolide derivatives, which exhibit essential pharmacological activities such as those that are anti-inflammatory, antibacterial, antitumor, antidiabetic, anti-HIV, antifeedant, and antiviral. However, what is noteworthy about this paper is summarizing the effects of andrographolide against cardiovascular disease, platelet activation, infertility, and NF-κB activation. Therefore, this paper is intended to provide evidence reported in relevant literature on qualitative research to assist scientists in isolating and characterizing bioactive compounds.

    Pain is highly prevalent in frail older people who often have multiple co-morbidities and multiple medicines. Rational prescribing of analgesics in frail older people is complex due to heterogeneity in drug disposition, comorbid medical conditions, polypharmacy and variability in analgesic response in this population. A critical issue in managing older people with pain is the need for judicious choice of analgesics based on a comprehensive medical and medication history. Care is needed in the selection of analgesic medicine to avoid drug-drug or drug-disease interactions. People living with dementia and cognitive impairment have suboptimal pain relief which in part may be related to altered pharmacodynamics of analgesics and challenges in the systematic assessment of pain intensity in this patient group. In the absence of rigorously controlled trials in frail older people and those with cognitive impairment a pharmacologically-guided approach can be used to optimize pain management which requires a systematic understanding of the pharmacokinetics and pharmacodynamics of analgesics in frail older people with or without changes in cognition.

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.

    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

    Full Text Available Background: the mental health services of the Pediatric Hospital of Cienfuegos receive all patients in the province that need to be hospitalized. Among them, children and adolescents functioning at the psychotic level are of great clinical and social importance. Objective: to describe the clinical characteristics and pharmacological treatment of psychotic patients treated in the mental health services. Methods: a case series study of 35 psychotic patients admitted to the mental health unit of the Pediatric Hospital of Cienfuegos was conducted between 2008 and 2012. Demographic variables, in addition to variables related to clinical data and pharmacotherapeutic aspects were analyzed. Results: sixty five point seven percent of patients were adolescents and 77.1% were of urban origin. The most common diagnoses were acute and transient psychotic disorder and schizophrenia. Sixty three percent had a family history of psychiatric disorder. Forty percent were treated with trifluoperazine and an equal percent took haloperidol. Psychotic symptoms were controlled in 58% of patients during the first weeks. Conclusion: white adolescent patients from urban areas with a family history of psychiatric illness predominated. They received regular psychiatric attention and experienced the symptoms for a short time before being treated. The most frequently prescribed medications were typical antipsychotic drugs, which caused adverse reactions in a third of the patients. In the first few weeks, psychotic symptoms were controlled in most patients, although half of them experienced a recurrence of symptoms, which evolved into conditions with worse prognosis.

    Salvia officinalis L. and Salvia lavandulaefolia L. have a longstanding use as traditional herbal remedies that can enhance memory and improve cognitive functions. Pharmacological actions of S. officinalis and S. lavandulaefolia on healthy subjects and on patients suffering of cognitive decline have been investigated. Aim of this review was to summarize published clinical trials assessing effectiveness and safety of S. officinalis and S. lavandulaefolia in the enhancement of cognitive performance in healthy subjects and neurodegenerative illnesses. Furthermore, to purchase a more complete view on safety of S. officinalis and S. lavandulaefolia, we collected and discussed articles regarding toxicity and adverse reactions. Eight clinical studies investigating on acute effects of S. officinalis on healthy subjects were included in the review. Six studies investigated on the effects of S. officinalis and S. lavandaeluaefolia on cognitive performance in healthy subjects. The two remaining were carried out to study the effects of sage on Azheimer's disease. Our review shows that S. officinalis and S. lavandulaefolia exert beneficial effects by enhancing cognitive performance both in healthy subjects and patients with dementia or cognitive impairment and is safe for this indication. Unfortunately, promising beneficial effects are debased by methodological issues, use of different herbal preparations (extracts, essential oil, use of raw material), lack of details on herbal products used. We believe that sage promising effects need further higher methodological standard clinical trials.

    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

    Suprofen is a potent, peripherally-acting, non-narcotic analgesic agent. The mechanism of action of the compound involves inhibition of prostaglandin biosynthesis and, perhaps, direct antagonism of the peripheral, pain inducing actions of prostaglandins, bradykinin and other pain mediators. Suprofen at a dose of 200 mg appears to be equal or greater in efficacy as an analgesic modality than those of ibuprofen, propoxyphene, naproxen and diflunisal or a combination of 650 mg aspirin plus 60 mg codeine. Its clinical utility has been amply demonstrated in the treatment of a number of types of pain including general and orthopedic surgery, episiotomy, post-partum pain, dysmenorrhea, dental pain and musculoskeletal disorders. Suprofen represents a new class of orally effective nonnarcotic analgesics with potential for effective clinical use in the treatment of pain.

    Full Text Available Aim: This paper describes how in a problem-based learning (PBL medical curriculum, having identified the learning outcomes, problems can be developed from real-life events for teaching-learning clinical pharmacology topics for which PBL cases might be inadequate. Such problems can be very interesting and educational. Methodology: Using the story of the development and withdrawal of rofecoxib (Vioxx ® , we developed a problem for undergraduate medical students to address important issues related to clinical pharmacology and therapeutics such as new drug development, preclinical testing, clinical trials, adverse drug reactions, professionalism, and critical appraisal of literature. These topics would otherwise be difficult to address in patient-based problems. Results: The evaluation of the problem based on pooled feedback from 57 tutorial groups, each comprising 8-10 students, collected over 5 years, supported the effectiveness of the problem. Conclusion: A systematic approach described in this paper can be used for the development and validation of educational material for introducing focal topics of pharmacology/clinical pharmacology integrated with other disciplines in innovative medical (and other health profession curricula.

    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.

    Full Text Available Arbor vitae (Thuja occidentalis L. is a native European tree widely used in homeopathy and evidence-based phytotherapy. Many reviews and monographs have been published on the herbal substance's description, mode of action and clinical use. However, no comprehensive evidence-based review is available. Therefore, our aim was to search MEDLINE databases and survey manufacturers for further details or unpublished data. This review presents the botany, ethnobotany and phytochemistry, especially the different contents of essential oil (Thujone in relation to different extraction procedures of this medicinal plant. Thuja's antiviral action and immunopharmacological potential, such as stimulatory and co-stimulatory effects on cytokine and antibody production and activation of macrophages and other immunocompetent cells, have been evaluated in numerous in vitro and in vivo investigations. Although no controlled trials have been conducted on Thuja occ alone, many clinical studies have been performed with a herbal medicinal product containing a special extract of Thuja occ and other immunostimulants, demonstrating its therapeutic efficacy and safety in respiratory tract infections.

    Voriconazole is a potent antifungal agent used for the treatment of invasive fungal infections caused by Aspergillus and Candida species in adult and pediatric patients. Voriconazole has a narrow therapeutic index and a large intra- and inter-individual pharmacokinetics (PK) variability. Several factors including non-linear PK, age, body weight, cytochrome P450 2C19 genotype, concomitant drugs, liver function, and food are responsible for the large variability in voriconazole PK. A combination of a narrow therapeutic index with a large PK variability results in treatment failure in many patients at clinically recommended doses. There is an urgent need to establish an optimal dosing regimen for pediatric patients 60 %) treatment failure rates. Therapeutic drug monitoring is commonly used in clinical practice to optimize the voriconazole dosing regimens in pediatric patients, but it is associated with several practical limitations. Implementation of a PK model-guided individualized dose selection will help in reducing the PK variability and will improve therapeutic outcomes. In this review, we have summarized the covariates influencing the PK of voriconazole in adult and pediatric patients, emphasizing that the clearance of voriconazole is significantly different between adult and pediatric patients owing to developmental changes in the major clearance pathways. Moreover, we have provided the limitations of the current dosing regimens and have proposed a new dosing method using a PK model-guided dose individualization of voriconazole in pediatric patients.

    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

    Two catechol-O-methyl transferase inhibitors are currently used as add-on therapy to levodopa for the amelioration of end-of-dose motor fluctuations in Parkinson's disease patients: entacapone, which has moderate efficacy and requires multiple dosing, and tolcapone, which has a poor safety profile. Opicapone (OPC) is a novel, long-acting, peripherally selective, once daily, third-generation catechol-O-methyl transferase inhibitor. Two Phase III clinical trials demonstrated OPC efficacy in reducing OFF-time by an average of about 60 min daily compared with placebo, without increasing ON-time with troublesome dyskinesias, with a good drug safety profile. In June 2016, the European Commission granted a marketing authorization valid throughout the European Union for OPC, indicated as adjunctive of levodopa decarboxylase inhibitors in adult patients with Parkinson's disease and end-of-dose motor fluctuations.

    Since the discovery of Toll, in the fruit fly Drosophila melanogaster, as the first described pattern recognition receptor (PRR) in 1996, many families of these receptors have been discovered and characterized. PRRs play critically important roles in pathogen recognition to initiate innate immune responses that ultimately link to the generation of adaptive immunity. Activation of PRRs leads to the induction of immune and inflammatory genes, including proinflammatory cytokines and chemokines. It is increasingly clear that many PRRs are linked to a range of inflammatory, infectious, immune, and chronic degenerative diseases. Several drugs to modulate PRR activity are already in clinical trials and many more are likely to appear in the near future. Here, we review the different families of mammalian PRRs, the ligands they recognize, the mechanisms of activation, their role in disease, and the potential of targeting these proteins to develop the anti-inflammatory therapeutics of the future.

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.

    Headache is one of the most common complaints in clinical practice. Few studies regarding headache in university students have been conducted in the Middle East. The objective of this study was to explore the prevalence, clinical characteristics, triggering factors and treatment options of headaches in university undergraduate students in Palestine/Middle East. Data were collected by interviewing a sample of 1900 students. The Headache Assessment Quiz was used to measure quality and severity of headache and to collect data on triggering factors and symptom management. A total of 1808 (95.2%) reported having at least one headache episode in the previous year. A positive family history of headache was found in 40% of students. The prevalence rate of frequent headache (tow or more episodes/month) was found in 1096 (60.9%) students; 613 women (55.9%). Of those having frequent headaches, 228 (20.8%) experienced moderate to severe episodes, 341 (31.2%) had pulsating, throbbing and pounding pain, and 274 (25%) had unilateral pain. The most common triggering factors among students with frequent headaches were: tension/stress (78.2%) and sleep deprivation (75.4%). Less than 5% of students sought medical assistance during headache episodes. Most students (79.1%) reported self-therapy with a single analgesic (53.4%), herbs (10.2%) or combination (15.5%), while 20.9% reported using no medication of any type to decrease pain. Paracetamol (48.5%) followed by ibuprofen (4.9%) were the most commonly used non-prescription analgesic drugs. Headache is a prevalent symptom in the college age population. Further research is needed to determine the prevalence of specific types of headaches. Healthcare providers are required to educate this population as well as to assist students in properly diagnosing and treating headache types. PMID:19673913

    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.

    Calcium polycarbophil is the calcium salt of polyacrylic acid crosslinked with divinyl glycol. It is chemically and physiologically inert. In dilute alkali it possesses marked hydrophilic capacity (60 to 100 times its weight), which is the basis for its therapeutic use. In daily dosages of 4 to 5 g in adults, it appears to be quite safe, is non-toxic, does not interfere with digestion or absorption, and does not cause gastrointestinal irritation. It appears to be effective in the treatment of both constipation and diarrhea due to functional or organic causes. Several days of continuous use are necessary before effectiveness becomes apparent. Clinical studies, of which there are relatively few, range from uncontrolled, unblinded evaluations of an almost anecdotal nature to well controlled, double-blind, crossover studies. Additional carefully controlled studies on dietary influences, exercise, and patient compliance would be helpful. Adverse effects, which are minimal, include epigastric fullness or heaviness, abdominal distention and bloating, and flatulence. As with all bulk-forming agents, calcium polycarbophil should not be used by persons who have stenotic lesions of the gastrointestinal tract.

  1. Clinical pharmacology of levosimendan.

    2007-01-01

    Levosimendan has been developed for the treatment of decompensated heart failure and is used intravenously when patients with heart failure require immediate initiation of drug therapy. It increases cardiac contractility and induces vasodilatation. The pharmacokinetics of levosimendan are linear at the therapeutic dose range of 0.05-0.2 microg/kg/minute. The short half-life (about 1 hour) of the parent drug, levosimendan, enables fast onset of drug action, although the effects are long-lasting due to the active metabolite OR-1896, which has an elimination half-life of 70-80 hours in patients with heart failure (New York Heart Association functional class III-IV). Although levosimendan is administered intravenously, it is excreted into the small intestine and reduced by intestinal bacteria to an amino phenolpyridazinone metabolite (OR-1855). This metabolite is further metabolised by acetylation to N-acetylated conjugate (OR-1896). The circulating metabolites OR-1855 and OR-1896 are formed slowly, and their maximum concentrations are seen on average 2 days after stopping a 24-hour infusion. The haemodynamic effects after levosimendan seem to be similar between fast and slow acetylators despite the fact that the enzyme N-acetyltransferase-2, which is responsible for the metabolism of OR-1855 to OR-1896, is polymorphically distributed in the population. Levosimendan reduces peripheral vascular resistance and has direct contractility-enhancing effects on the failing left ventricle. It also improves indices of diastolic function and seems to improve the function of stunned myocardium. Despite an improvement in ventricular function, levosimendan does not increase myocardial oxygen uptake significantly. An increase in coronary blood flow and a reduction in coronary vascular resistance have been observed. Levosimendan reduces plasma brain natriuretic peptide (BNP) and N-terminal pro-BNP (NT-proBNP) levels substantially, and a decrease in plasma endothelin-1 has been observed. Levosimendan also exerts beneficial effects on proinflammatory cytokines and apoptosis mediators. The effects of a 24-hour levosimendan infusion on filling pressure, ventricular function and BNP, as well as NT-proBNP, last for at least 7 days.

    Flupirtine is neither an opioid nor a non steroidal anti-inflammatory drug (NSAID) producing its analgesic action through blockade of glutamate N-methyl-D-aspartate receptor. It is devoid of adverse effects of routinely used analgesic drugs, but is equally efficacious in reducing pain sensation. It has a distinctive mechanism of action, exerting a dual therapeutic effect with both analgesic and muscle relaxant properties that has utility in the treatment of pain, including that associated with muscle tension.

    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.

    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.

    Full Text Available Abstract Background A sound knowledge of pathophysiology of a disease and clinical pharmacology and therapeutics (CPT of a drug is required for safe and rational prescribing. 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. The interns would likely prescribe antibiotics (71, 87.6%, nonsteroidal analgesics (66, 81.4%, diuretics (55, 67.9%, sedatives (52, 62.9%, and insulin and oral hypoglycaemics (43, 53% with confidence and unsupervised. The higher the numbers of clinical rotations done, the more confident were the respondents to prescribe unsupervised (χ2 = 19.98, P 2 = 11.57, P 2 = 11.25, P Conclusion Undergraduate CPT teaching in Nigeria appears to be deficient.

    2013-05-01

    In this personal review I describe my early expectations and experiences when I first came to work with Prof. Folke Sjöqvist as a training fellow in the early 1970s. At that time Prof. Sjöqvist and his unit had already earned an international reputation, and in the following decades this success has been magnified many times. Although a description of the research performed by Prof. Sjöqvist during his long career is not the main objective of this article, it is clear that the research carried out in his unit has been instrumental in the development of his international reputation. Over an 18-year period from 1994 onwards, some 272 papers bearing the name of Folke Sjöqvist have been cited over 13,000 times, with an average of over 50 citations per paper. In terms of training clinical pharmacologists from around the world, at the last count 112 individuals from 37 different countries have received a substantial part of their training in his unit. As another measure of his world-wide success, 33 individuals from 18 different countries who received a substantial part of their training in his unit between 1968 and 1996 have gone on to become professors of clinical pharmacology. Prof. Sjöqvist has been requested to consult on various aspects of clinical pharmacology in 15 different countries, from Russia to Spain and from Egypt to Latvia. Here I describe the long-term involvement that Prof. Sjöqvist has had with IUPHAR (now the International Union of Basic and Clinical Pharmacology) and with institutions such as the World Health Organisation (WHO). In particular, I recount his role in the long-term saga involved in updating the original WHO manifesto on clinical pharmacology published in 1970 up to the eventual success of the new manifesto published by WHO in 2012. Finally, I briefly describe the international honours that have been bestowed on Prof. Sjöqvist, including various prizes, designated lectureships and honorary Doctorates (5). Taken together, these

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

    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

    Anticoagulants are beneficial for prevention and treatment of venous thromboembolism and stroke prevention in atrial fibrillation. The development of target-specific oral anticoagulants is changing the landscape of anticoagulation therapy and created growing interest on this subject. Understanding the pharmacology of different anticoagulants is the first step to adequately treat patients with best available therapy while avoiding serious bleeding complications. This article reviews the pharmacology of the main anticoagulant classes (vitamin K antagonists, direct oral anticoagulants, and heparins) and their clinical indications based on evidence-based data currently available in the literature.

  14. Pharmacological management of sepsis

    1985-01-01

    Systemic sepsis continues to be the most-difficult management problem in caring for the combat casualty. The complications of sepsis pervade all areas of injury to soldiers in the field, whether it is mechanical (missiles), thermal (burns), chemical, biological, or radiation injury. With the advent of tactical nuclear weapons, the problem of sepsis will be much higher in future wars than has previously been experienced through the world. The purpose of this chapter is a) to review the data suggesting pharmacological agents that may benefit the septic patient, and b) to emphasize the adjunctive therapies that should be explored in clinical trials. The pharmacological management of sepsis remains controversial. Most of the drugs utilized clinically treat the symptoms of the disease and are not necessarily directed at fundamental mechanisms that are known to be present in sepsis. A broad data base is emerging, indicating that NSAID should be used in human clinical trials. Prostaglandins are sensitive indicators of cellular injury and may be mediators for a number of vasoactive chemicals. Opiate antagonists and calcium channel blockers require more in-depth data; however, recent studies generate excitement for their potential use in the critically ill patient. Pharmacological effects of antibiotics, in concert with other drugs, suggest an entirely new approach to pharmacological treatment in sepsis. There is no doubt that new treatment modalities or adjunctive therapies must be utilized to alter the poor prognosis of severe sepsis that we have observed in the past 4 decades.

    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.

    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.

    The clinical usefulness of misonidazole (MISO) and desmethylmisonidazole (DMM) is severely limited by neurotoxicity. Based on theoretical considerations and on laboratory data suggesting that pyridoxine (PN) decreased MISO toxicity in mice. The authors attempted to ameliorate the clinical neuropathy of DMM using oral PN. Pharmacokinetic analysis suggested interaction of PN and DMM but no protection against neuropathy was observed. Serial experiments with C3H and BALB/c mice were done using various forms of vitamin B/sub 6/ (PN, pyridoxal, pyridoxal phosphate) administered orally and i.p. No consistent protection was observed. Dexamethasone did not alter MISO toxicity in mice, contrary to the clinical findings. They conclude that vitamin B/sub 6/ is not useful in preventing clinical neurotoxicity of MISO or DMM.

    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.

    Full Text Available Aims. Several treatments have been proposed to slow down progression of Retinitis pigmentosa (RP, a hereditary retinal degenerative condition leading to severe visual impairment. The aim of this study is to systematically review data from randomized clinical trials (RCTs evaluating safety and efficacy of medical interventions for the treatment of RP. Methods. Randomized clinical trials on medical treatments for syndromic and nonsyndromic RP published up to December 2014 were included in the review. Visual acuity, visual field, electroretinogram, and adverse events were used as outcome measures. Results. The 19 RCTs included in this systematic review included trials on hyperbaric oxygen delivery, topical brimonidine tartrate, vitamins, docosahexaenoic acid, gangliosides, lutein, oral nilvadipine, ciliary neurotrophic factor, and valproic acid. All treatments proved safe but did not show significant benefit on visual function. Long term supplementation with vitamin A showed a significantly slower decline rate in electroretinogram amplitude. Conclusions. Although all medical treatments for RP appear safe, evidence emerging from RCTs is limited since they do not present comparable results suitable for quantitative statistical analysis. The limited number of RCTs, the poor clinical results, and the heterogeneity among studies negatively influence the strength of recommendations for the long term management of RP patients.

    2012-10-01

    Antipsychotics are frequently used in elderly patients to treat a variety of conditions, including schizophrenia. While extensively studied for their impact in younger populations, there is comparatively limited evidence about the effectiveness of these agents in older patients. Further complicating this situation are the high comorbidity rates (both psychiatric and medical) in the elderly; age-related changes in pharmacokinetics that lead to a heightened proclivity for adverse effects; and the potential for multiple, clinically relevant drug interactions. With this background in mind, we review diagnostic and treatment-related issues specific to elderly patients suffering from schizophrenia. We then focus on the potential role of the most recently approved second-generation antipsychotics, paliperidone (both the extended-release oral formulation and the long-acting injectable formulation), iloperidone, asenapine and lurasidone, given the limited clinical experience with these agents in the elderly. While there is limited data to support their safety, tolerability and efficacy in older patients with schizophrenia, each has unique characteristics that should be considered when used in this population.

    Irritable bowel syndrome (IBS) is a functional bowel disorder characterized by abdominal pain or discomfort and abnormal defecation. Polycarbophil calcium, a water-absorbing polymer, is expected to improve stool consistency. Polycarbophil calcium decalcified under the acidic condition and then absorbed 70 times its weight of water under the neutral condition. In in situ experiments using rat jejunum and colon, polycarbophil decreased water absorption by the intestine without affecting water secretion. Polycarbophil inhibited prostaglandin E2-, 5-hydroxy-L-tryptophan- and castor oil-induced diarrhea in mice or rats. Polycarbophil calcium also inhibited sennoside-induced diarrhea in dogs. Polycarbophil increased the weight of feces in naive or low-fiber diet feeding rats. In naive dogs, polycarbophil calcium increased stool frequency, stool weight and moisture. Polycarbophil was not absorbed from the gastrointestine, not metabolized and eliminated into feces in rats and dogs. Polycarbophil calcium did not affect the absorption of coadministered drugs in dogs. In the dose-finding clinical study for IBS, polycarbophil calcium was effective both in diarrhea and constipation. In the Phase III study, polycarbophil calcium was superior to trimebutine maleate in efficacy and equal in safety. Emesis/vomiting and thirst were observed, but episodes of diarrhea or constipation by excessive action were few. Polycarbophil calcium seems promising as an anti-IBS agent.

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

    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.

    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

    Bleomycin pharmacokinetics were studied by radioimmunoassay in 11 patients who received 7-30 U intravenously (IV) and eight patients who received 4-30 U subcutaneously (SC). For patients who received IV bleomycin plasma disappearance was biphasic, with a mean initial half-life of 0.26 h and a terminal half-life of 2.3 h. Mean plasma drug clearance was 67.8 ml/min/m/sup 2/ and the volume of distribution was 13.2 l/m/sup 2/. Urinary excretion accounted for 63.9% of the drug in 24 h. After SC administration peak plasma levels occurred in 1.1 h, with a mean elimination half-life of 4.3 h. Mean plasma drug clearance was 60.5 ml/min/m/sup 2/ and the volume of distribution was 19.2 l/m/sup 2/. Bleomycin plasma clearance correlated well with serum creatinine (r/sup 2/=0.72). Bleomycin has a rapid plasma elimination and urinary excretion. Bleomycin bioavailability after SC administration appears comparable to that seen after IV administration as determined by the areas under the plasma disappearance curves. Prolonged plasma levels are seen after SC injection, suggesting this route of administration can produce plasma concentrations comparable to those attained with continuous IV infusions.

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.

    Decades of practice in psychiatriy and hundreds of clinical trials have demonstrated the efficacy of antipsychotics on symptoms of schizophrenia. Recently, the knowledge acquired from non-interventional studies have supplemented the information needed in daily practice by raising the issue of efficiency by incorporating not only the effectiveness and safety of treatment but also its acceptability by the patient. Adherence to antipsychotic treatment has become the key issue of the prognosis. The pharmacological management of patients with an acute episode of schizophrenia requires rapid therapeutic decisions to treat a patient who is likely to be sometimes unhelpful and agitated. The choice of treatment will have a significant impact on the prevention of psychotic relapses, on the overall prognosis and on the quality of life of the patient. In many countries of the recommendations and treatment algorithms for the management of acute psychosis were distributed, considering factors specific to the patient and his environment, his mental characteristics and local care setting.

    The wide variety of first-line agents available for managing high blood pressure include diuretics, beta adrenergic receptor blockers, alpha adrenergic receptor blockers, angiotensin converting enzyme inhibitors, and calcium channel blockers. Supplemental agents used for second-line therapy and special indications, such as pregnancy and hypertensive emergencies, include angiotensin receptor blockers, central-acting agents, direct vasodilators, and adrenergic neuron inhibitors. Selection of agents for particular patients requires consideration of research-based evidence for positive long-term outcomes and of the unique patient profile of age, race, co-morbidities, and lifestyle. A thorough understanding of the pharmacology (mechanism, pharmacokinetics, adverse effects and drug interactions, clinical use) of antihypertensive agents is an essential foundation for nursing practice in women's health.

    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.

    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.

    intradural. La metadona es otro fármaco al que se le ha observado una selectividad medular moderada tras su administración epidural. Sin embargo, su prolongada vida media puede resultar en su acumulación plasmática y presencia de efectos supraespinales a lo largo del tiempo. La administración epidural de fentanilo ofrece muy pocas ventajas sobre su utilización intravenosa, salvo en obstetricia donde parece producir una analgesia selectiva medular de grado moderado. Finalmente, la administración epidural de sufentanilo o alfentanilo parece producir analgesia por recaptación sistémica y redistribución hacia los receptores opioides cerebrales.The history of intrathecal and epidural anaesthesia is in parallel with the development of general anaesthesia. The first published report on opioids for intrathecal anaesthesia belongs to a Romanian surgeon, who presented his experience at Paris in 1901. It was almost a century before the opioids were used for epidural analgesia. Epidural and intrathecal opioids are today part of a routine regimen for intra and postoperative analgesia. Over the last 30 years, the use of epidural opioids has became a standard for analgesia in labor and delivery, and for the management of acute and chronic pain. It has been widely asumed that any opioid placed in the epidural or intrathecal spaces will produce highly selective spinally mediated analgesia that is superior to that produced by other analgesic techniques. Unfortunately, this is simply not true. In fact, multiples opioids are currently employed for spinal use despite the fact that clinical evidence has shown that spinal administration does not produce analgesia with a selective spinal mechanism or the analgesia produced is not superior to that produced by intravenous administration. Appropriate use of spinal opioids necessitates under-standing the physiology and clinical pharmacology of these drugs and which opioids produce selective spinal analgesia and which do not. In short, spinal

    When people with dementia demonstrate challenging behavioural and psychological symptoms of dementia, the levels of stress experienced by their carers increases. Furthermore, there is an increased likelihood that the person will be prematurely admitted to a residential care facility. The adverse side-effects that have been associated with the use of antipsychotic medications in older people with dementia have given rise to a renewed emphasis on the use of non-pharmacological approaches to manage challenging behaviours. This article describes the approaches taken by the multi-disciplinary team of a Dementia Behaviour Management Advisory Service in Australia to support people with dementia who have challenging behaviours by using non-pharmacological interventions.

    2004-01-01

    Dronabinol (Delta 9-tetrahydocannabinol, THC), the main source of the pharmacological effects caused by the use of cannabis, is an agonist to both the CB1 and the CB2 subtype of cannabinoid receptors. It is available on prescription in several countries. The non-psychotropic cannabidiol (CBD), some analogues of natural cannabinoids and their metabolites, antagonists at the cannabinoid receptors and modulators of the endogenous cannabinoid system are also promising candidates for clinical research and therapeutic uses. Cannabinoid receptors are distributed in the central nervous system and many peripheral tissues including spleen, leukocytes; reproductive, urinary and gastrointestinal tracts; endocrine glands, arteries and heart. Five endogenous cannabinoids have been detected so far, of whom anandamide and 2-arachidonylglycerol are best characterized. There is evidence that besides the two cannabinoid receptor subtypes cloned so far additional cannabinoid receptor subtypes and vanilloid receptors are involved in the complex physiological functions of the cannabinoid system that include motor coordination, memory procession, control of appetite, pain modulation and neuroprotection. Strategies to modulate their activity include inhibition of re-uptake into cells and inhibition of their degradation to increase concentration and duration of action. Properties of cannabinoids that might be of therapeutic use include analgesia, muscle relaxation, immunosuppression, anti-inflammation, anti-allergic effects, sedation, improvement of mood, stimulation of appetite, anti-emesis, lowering of intraocular pressure, bronchodilation, neuroprotection and antineoplastic effects.

    Full Text Available Abstract Background Fabry disease (FD is a genetic disorder resulting from deficiency of the lysosomal enzyme α-galactosidase A (α-Gal A, which leads to globotriaosylceramide (GL-3 accumulation in multiple tissues. We report on the safety and pharmacodynamics of migalastat hydrochloride, an investigational pharmacological chaperone given orally at 150 mg every-other-day. Methods Two open-label uncontrolled phase 2 studies of 12 and 24 weeks (NCT00283959 and NCT00283933 in 9 males with FD were combined. At multiple time points, α-Gal A activity and GL-3 levels were quantified in blood cells, kidney and skin. GL-3 levels were also evaluated through skin and renal histology. Results Compared to baseline, increased α-Gal A activity of at least 50% was demonstrated in blood, skin and kidney in 6 of 9 patients. Patients’ increased α-Gal A activities paralleled the α-Gal A increases observed in vitro in HEK-293 cells transfected with the corresponding mutant form of the enzyme. The same 6 patients who demonstrated increases of α-Gal A activity also had GL-3 reduction in skin, urine and/or kidney, and had α-Gal A mutations that responded in transfected cells incubated with the drug. The 3 patients who did not show a consistent response in vivo had α-Gal A mutations that did not respond to migalastat HCl in transfected cells. Migalastat HCl was well tolerated. Conclusions Migalastat HCl is a candidate pharmacological chaperone that provides a novel genotype-specific treatment for FD. It enhanced α-Gal A activity and resulted in GL-3 substrate decrease in patients with responsive GLA mutations. Phase 3 studies are ongoing.

  2. Pharmacological disruption of maladaptive memory.

    Many psychiatric disorders are characterized by intrusive, distracting, and disturbing memories that either perpetuate the illness or hinder successful treatment. For example, posttraumatic stress disorder (PTSD) involves such strong reemergence of memories associated with a traumatic event that the individual feels like the event is happening again. Furthermore, drug addiction is characterized by compulsive use and repeated relapse that is often driven by internal memories of drug use and/or by exposure to external stimuli that were associated with drug use. Therefore, identifying pharmacological methods to weaken the strength of maladaptive memories is a major goal of research efforts aimed at finding new treatments for these disorders. The primary mechanism by which memories could be pharmacologically disrupted or altered is through manipulation of memory reconsolidation. Reconsolidation occurs when an established memory is remembered or reactivated, reentering a labile state before again being consolidated into long-term memory storage. Memories are subject to disruption during this labile state. In this chapter we will discuss the preclinical and clinical studies identifying potential pharmacological methods for disrupting the integrity of maladaptive memory to treat mental illness.

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.

    Cloning of the human erythropoietin (EPO) gene and development of the first recombinant human erythropoietin (rHuEPO) drug were truly breakthroughs. This allowed a deeper understanding of the structure and pharmacology of rHuEpo, which in turn inspired the discovery and development of additional erythropoiesis-stimulating agents (ESAs). In vivo specific activity and serum half-life of rHuEPO are influenced by the amount and structure of the attached carbohydrate. Increased numbers of sialic acids on carbohydrate attached to rHuEPO correlated with a relative increase in in-vivo-specific activity and increased serum half-life. The effect of increasing the number of sialic-acid-containing carbohydrates on in-vivo-specific activity was explored. Initial research focused on solving the problem of how the protein backbone could be engineered so a cell would add more carbohydrate to it. Additional work resulted in darbepoetin alfa, a longer-acting molecule with two additional carbohydrate chains. PMID:20127232

    2012-09-01

    Almost uniquely in pharmacology, drug safety assessment is driven by the need for elaboration and validation of methods for detecting drug actions. This is the 9th consecutive year that the Journal of Pharmacological and Toxicological Methods (JPTM) has published themed issues arising from the annual meeting of the Safety Pharmacology Society (SPS). The SPS is now past its 10th year as a distinct (from pharmacology to toxicology) discipline that integrates safety pharmacologists from industry with those in academia and the various global regulatory authorities. The themes of the 2011 meeting were (i) the bridging of safety assessment of a new chemical entity (NCE) between all the parties involved, (ii) applied technologies and (iii) translation. This issue of JPTM reflects these themes. The content is informed by the regulatory guidance documents (S7A and S7B) that apply prior to first in human (FIH) studies, which emphasize the importance of seeking model validation. The manuscripts encompass a broad spectrum of safety pharmacology topics including application of state-of-the-art techniques for study conduct and data processing and evaluation. This includes some exciting novel integrated core battery study designs, refinements in hemodynamic assessment, arrhythmia analysis algorithms, and additionally an overview of safety immunopharmacology, and a brief survey discussing similarities and differences in business models that pharmaceutical companies employ in safety pharmacology, together with SPS recommendations on 'best practice' for the conduct of a non-clinical cardiovascular assessment of a NCE.

    2014-09-01

    The International Conference on Harmonization E14 guidance for the clinical evaluation of QT/QTc interval prolongation requires almost all new drugs to undergo a dedicated clinical study, primarily in healthy volunteers, the so-called TQT study. Since 2005, when the E14 guidance was implemented in United States and Europe, close to 400 TQT studies have been conducted. In February 2012, the Cardiac Safety Research Consortium held a think tank meeting at Food and Drug Administration's White Oak campus to discuss whether "QT assessment" can be performed as part of routine phase 1 studies. Based on these discussions, a group of experts convened to discuss how to improve the confidence in QT data from early clinical studies, for example, the First-Time-in-Human trial, through collection of serial electrocardiograms and pharmacokinetic samples and the use of exposure response analysis. Recommendations are given on how to design such "early electrocardiogram assessment," and the limitation of not having a pharmacologic-positive control in these studies is discussed. A research path is identified toward collecting evidence to replace or provide an alternative to the dedicated TQT study.

  13. Mitochondrial biogenesis: pharmacological approaches.

    Science.gov (United States)

    Valero, Teresa

    2014-01-01

    Organelle biogenesis is concomitant to organelle inheritance during cell division. It is necessary that organelles double their size and divide to give rise to two identical daughter cells. Mitochondrial biogenesis occurs by growth and division of pre-existing organelles and is temporally coordinated with cell cycle events [1]. However, mitochondrial biogenesis is not only produced in association with cell division. It can be produced in response to an oxidative stimulus, to an increase in the energy requirements of the cells, to exercise training, to electrical stimulation, to hormones, during development, in certain mitochondrial diseases, etc. [2]. Mitochondrial biogenesis is therefore defined as the process via which cells increase their individual mitochondrial mass [3]. Recent discoveries have raised attention to mitochondrial biogenesis as a potential target to treat diseases which up to date do not have an efficient cure. Mitochondria, as the major ROS producer and the major antioxidant producer exert a crucial role within the cell mediating processes such as apoptosis, detoxification, Ca2+ buffering, etc. This pivotal role makes mitochondria a potential target to treat a great variety of diseases. Mitochondrial biogenesis can be pharmacologically manipulated. This issue tries to cover a number of approaches to treat several diseases through triggering mitochondrial biogenesis. It contains recent discoveries in this novel field, focusing on advanced mitochondrial therapies to chronic and degenerative diseases, mitochondrial diseases, lifespan extension, mitohormesis, intracellular signaling, new pharmacological targets and natural therapies. It contributes to the field by covering and gathering the scarcely reported pharmacological approaches in the novel and promising field of mitochondrial biogenesis. There are several diseases that have a mitochondrial origin such as chronic progressive external ophthalmoplegia (CPEO) and the Kearns- Sayre syndrome (KSS

    2012-01-01

    Laboratory evidence of the presence and concentration of a drug in a person who has come to harm is often helpful in forensic pharmacology, and may be crucial. However, its value depends on two critical interpretations by the expert. First, the expert must make a careful analysis of the relationship between the results as measured in the sample and the drug in the patient at the time that harm occurred. That is especially difficult with post-mortem samples. Secondly, the expert must syntheses the laboratory information with the available clinical history and clinical or pathological findings. Even in the most favourable circumstances, when the sample is correctly obtained, identified, and analyzed, it can be hard to say that beyond reasonable doubt a given concentration had a given effect.

    1989-01-01

    In this second article in the two-part series on pharmacology in space, Claire Lathers and colleagues discuss the pharmacology of drugs used to control motion sickness in space and note that the pharmacology of the 'ideal' agent has yet to be worked out. That motion sickness may impair the pharmacological action of a drug by interfering with its absorption and distribution because of alteration of physiology is a problem unique to pharmacology in space. The authors comment on the problem of designing suitable ground-based studies to evaluate the pharmacological effect of drugs to be used in space and discuss the use of salivary samples collected during space flight to allow pharmacokinetic evaluations necessary for non-invasive clinical drug monitoring.

    2008-04-01

    Obesity is reaching epidemic proportions worldwide and it is correlated with various comorbidities, among which the most relevant are diabetes mellitus, arterial hypertension, and cardiovascular diseases. Obesity management is a modern challenge because of the rapid evolution of unfavorable lifestyles and unfortunately there are no effective treatments applicable to the large majority of obese/overweight people. The current medical attitude is to treat the complications of obesity (e.g. dyslipidemia, hypertension, diabetes, and cardiovascular diseases). However, the potential of treating obesity is enormous, bearing in mind that a volitional weight loss of 10 kg is associated with important risk factor improvement: blood pressure -10 mmHg, total cholesterol -10%, LDL cholesterol -15%, triglycerides -30%, fasting glucose -50%, HDL cholesterol +8%. Drug treatment for obesity is an evolving branch of pharmacology, burdened by severe side effects and consequences of the early drugs, withdrawn from the market, and challenged by the lack of long-term data on the effect of medications on obesity-related morbidity and mortality, first of all cardiovascular diseases. In Europe three antiobesity drugs are currently licensed: sibutramine, orlistat, and rimonabant; important trials with clinical endpoints are ongoing for sibutramine and rimonabant. While waiting for their results, it is convenient to evaluate these drugs for their effects on body weight and cardiometabolic risk factors. Sibutramine is a centrally acting serotonin/noradrenaline reuptake inhibitor that mainly increases satiety. At the level of brown adipose tissue, sibutramine can also facilitate energy expenditure by increasing thermogenesis. The long-term studies (five) documented a mean differential weight reduction of 4.45 kg for sibutramine vs placebo. Considering the principal studies, attrition rate was 43%. This drug not only reduces body weight and waist circumference, but it decreases triglycerides and

    Gefitinib and erlotinib are the two anti-epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) approved for treatment of advanced NSCLC patients. These drugs target one of the most important pathways in lung carcinogenesis and are able to exploit the phenomenon of 'oncogene addiction', with different efficacy according to EGFR gene mutational status in tumor samples. Gefitinib has been approved only for EGFR mutation bearing patients regardless the line of treatment, while erlotinib is also indicated in patients without EGFR mutation who undergo second- or third-line treatment. Some studies evaluated the main differences between these drugs both for direct comparison and to improve their sequential use. In particular, toxicity profile resulted partially different, and these observations may be explained by several molecular and pharmacokinetic features. Therefore, this review integrates preclinical data with clinical evidences of TKIs to guide the optimization of currently available treatments in advanced NSCLC patients.

    Alogliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor that is a class of relatively new oral hypoglycaemic drugs used in patients with type 2 diabetes (T2DM), can be used as monotherapy or in combination with other anti-diabetic agents, including metformin, pioglitazone, sulfonylureas and insulin with a considerable therapeutic effect. Alogliptin exhibits favorable pharmacokinetic and pharmacodynamic profiles in humans. Alogliptin is mainly metabolized by cytochrome P450 (CYP2D6) and CYP3A4. Dose reduction is recommended for patients with moderate or worse renal impairment. Side effects of alogliptin include nasopharyngitis, upper-respiratory tract infections and headache. Hypoglycaemia is seen in about 1.5% of the T2DM patients. Rare but severe adverse reactions such as acute pancreatitis, serious hypersensitivity including anaphylaxis, angioedema and severe cutaneous reactions such as Stevens-Johnson syndrome have been reported from post-marketing monitoring. Pharmacokinetic interactions have not been observed between alogliptin and other drugs including glyburide, metformin, pioglitazone, insulin and warfarin. The present review aimed to update the clinical information on pharmacodynamics, pharmacokinetics, adverse effects and drug interactions, and to discuss the future directions of alogliptin.

    2013-01-01

    Safety pharmacology entails the assessment of the potential risks of novel pharmaceuticals for human use. As detailed in the ICH S7A guidelines, safety pharmacology for drug discovery involves a core battery of studies on three vital systems: central nervous (CNS), cardiovascular (CV), and respiratory. Primary CNS studies are aimed at defining compound effects on general behavior, locomotion, neuromuscular coordination, seizure threshold, and vigilance. The primary CV test battery includes an evaluation of proarrhythmic risk using in vitro tests (hERG channel and Purkinje fiber assays) and in vivo measurements in conscious animals via telemetry. Comprehensive cardiac risk assessment also includes full hemodynamic evaluation in a large, anesthetized animal. Basic respiratory function can be examined in conscious animals using whole-body plethysmography. This allows for an assessment of whether the sensitivity to respiratory-depressant effects can be enhanced by exposure to increased CO2 . Other safety pharmacology topics detailed in this unit are the timing of such studies, ethical and animal welfare issues, and statistical evaluation. PMID:24510755

    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.

    2016-02-01

    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.

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.

  13. [Pharmacological treatment of hyperinflation].

    Science.gov (United States)

    Devillier, P; Roche, N

    2009-06-01

    Introduction Lung hyperinflation leads to breathlessness, limitation in exercise capacity and tolerance, and impaired quality of life. Thus, it is important to target this key and characteristic feature of COPD. Current knowledge Available pharmacological approaches rely mainly on bronchodilators, in particular beta2 agonists and anticholinergic agents. These treatments act through the reduction of expiratory airflow limitation. However, changes in classical indices of airflow obstruction do not accurately predict effects on hyperinflation and symptoms. The decrease in operating lung volumes (as reflected by inspiratory capacity or functional residual capacity) at rest and during exercise is one of the mechanisms by which these treatments improve quality of life and maybe also decrease the impact of exacerbations. The effect of beta2 agonists on hyperinflation might be amplified by concurrent treatment with inhaled corticosteroids. Perspectives The effect of new treatments targeting airways inflammation on hyperinflation remains to be explored. Conclusions Measuring the reduction in the degree of lung hyperinflation allows a better understanding of the symptomatic effect of COPD pharmacological treatments.

  14. Non-pharmacological approaches to alleviate distress in dementia care.

    2015-11-25

    Distress is one of the most common clinical manifestations associated with dementia. Pharmacological intervention may be appropriate in managing distress in some people. However, best practice guidelines advocate non-pharmacological interventions as the preferred first-line treatment. The use of non-pharmacological interventions encourages healthcare professionals to be more person-centred in their approach, while considering the causes of distress. This article provides healthcare professionals with an overview of some of the non-pharmacological approaches that can assist in alleviating distress for people living with dementia including: reminiscence therapy, reality orientation, validation therapy, music therapy, horticultural therapy, doll therapy and pet therapy. It provides a summary of their use in clinical practice and links to the relevant literature. PMID:26602678

  18. Introduction to the clinical pharmacology of medetomidine.

    Science.gov (United States)

    Vainio, O

    1989-01-01

    Medetomidine is a sedative and analgesic drug intended for use in dogs and cats but it can also be successfully used in many other species. The effect of medetomidine is dose dependent at the recommended dose range (10-80 micrograms/kg for dogs and 50-150 micrograms/kg for cats). At doses higher than the recommended ones the strength of sedation does not increase, only the duration of the effect. From the cardiovascular changes induced with medetomidine, the profound bradycardia is most prominent. It can be transiently prevented with atropine or glycopyrrolate medication. An initial increase in arterial blood pressure followed by a longer lasting slightly hypotensive or normotensive period can be observed. Respiratory frequency tends to decrease but the changes stay within normal limits for resting animals. Vomiting may occur during the induction period of sedation. Occasional muscle jerks can be observed. Hypothermia has been reported in every animal sedated with medetomidine. Medetomidine can be used as preanaesthetic prior to ketamine, barbiturate and halothane anaesthesia. PMID:2571283

    Guslandi, M

    1994-04-01

    Pinaverium bromide is a locally acting spasmolytic agent of the digestive tract. Its mechanism of action relies upon inhibition of calcium ion entrance into smooth muscle cells (calcium-antagonist effect). In humans pinaverium facilitates gastric emptying and decreases intestinal transit time in patients with constipation. Pinaverium is very effective in improving symptoms of irritable bowel syndrome (abdominal pain, gas, diarrhea or constipation). In this respect the drug proved to be significantly superior to placebo, at least as effective as trimebutine and on the whole more active than otilonium and prifinium bromide, being always extremely well tolerated.

    Fluoxetine (30 mg), administered for 7 days to normal volunteers, produced a 66% inhibition of tritiated serotonin uptake into platelets. Plasma concentrations of fluoxetine correlated positively with inhibition of serotonin uptake. Fluoxetine is well absorbed after oral administration in both the fed and fasted states and demonstrates dose proportionality. Fluoxetine disappears from plasma with a half-life of 1-3 days; its metabolite norfluoxetine has a plasma half-life of 7-15 days. After administration of /sup 14/C-fluoxetine, approximately 65% of the administered dose of radioactivity is recovered in urine and about 15% in feces. Fluoxetine, given as a single dose or in multiple doses over 8 days, did not produce significant effects on the plasma disappearance of warfarin, diazepam, tolbutamide, or chlorothiazide. Coadministration of fluoxetine and ethanol did not result in an increase from control values in the blood ethanol levels, nor did it produce significant changes in physiologic, psychometric, or psychomotor activity. Pharmacokinetics of fluoxetine in the elderly and normal volunteers appear to be similar. In addition, pharmacokinetic analyses in patients with varying degrees of renal impairment did not show significant differences from healthy subjects.

  10. Problem-based learning and teaching of medical pharmacology.

    Kwan, Chiu-Yin

    2002-07-01

    In the Faculty of Health Sciences at McMaster University, the traditional discipline-based boundaries dividing the teaching and learning of basic medical sciences, such as physiology and pharmacology, do not exist. For more than 3 decades, student-centered, self-directed problem-based learning (PBL) has been the main form of instruction for students learning pharmacology within the medical curriculum and the pharmacological issues are always embedded within a health-care problem, with consideration of many other relevant non-pharmacological issues. In PBL, pedagogic emphasis is placed on the process of learning via constructive inquiry rather than cumulative acquisition of factual knowledge. For the science students, typically in the Biology/Pharmacology cooperative courses, both student-centered learning and teacher-centered teaching approaches are being used. In this case, the PBL approach is adopted to complement the conventional lectures at the course level. For medical students, PBL continues to be the major form of instruction in a small-group tutorial setting at the curricular level. The PBL curriculum is integrated across organ systems (cardiovascular, renal, respiratory, gastrointestinal, neural, etc) and across the life cycle, spanning population- and behavior-related perspectives, rather than being recreated from discrete disciplinary areas (such as physiology, anatomy, biochemistry, pharmacology, and community medicine). Those students who lack a pharmacology background or wish to enhance their pharmacological knowledge can take a block elective or horizontal elective in pharmacology. Unlike science students, medical students need to sort out pharmacological principles from the overload of information, to integrate them into the clinically relevant situations, and to ultimately apply them to the management of patients' illness. This is most effectively achieved in a student-centered environment conducive to life-long learning. PMID:12107627

    The galls of Quercus infectoria (Fagaceae), a commonly available plant in Iran, were studied pharmacologically. Two fractions were employed, a dried acetone-treated methanol extract dissolved in water (Fraction A) and a subfraction prepared by chloroform-methanol extraction (Fraction B). Fraction A was active as an analgesic in rats and significantly reduced blood sugar levels in rabbits. Fraction B had CNS depressant activity. Data obtained with a treadmill indicated a decreased activity ratio by Fraction B, suggesting a possible interference in motor coordination. It potentiated the barbiturate sleeping time significantly without changing the onset time or the loss of the righting reflex. In addition, Fraction B exhibited a moderate antitremorine activity by causing a delay in the onset and a decrease in the severity of tremorine-induced tremors. The local anesthetic action of Fraction B was evident due to the complete blockade of the isolated frog sciatic nerve conduction. PMID:1032663

    Mulloy, Barbara; Hogwood, John; Gray, Elaine; Lever, Rebecca; Page, Clive P

    2016-01-01

    Heparin has been recognized as a valuable anticoagulant and antithrombotic for several decades and is still widely used in clinical practice for a variety of indications. The anticoagulant activity of heparin is mainly attributable to the action of a specific pentasaccharide sequence that acts in concert with antithrombin, a plasma coagulation factor inhibitor. This observation has led to the development of synthetic heparin mimetics for clinical use. However, it is increasingly recognized that heparin has many other pharmacological properties, including but not limited to antiviral, anti-inflammatory, and antimetastatic actions. Many of these activities are independent of its anticoagulant activity, although the mechanisms of these other activities are currently less well defined. Nonetheless, heparin is being exploited for clinical uses beyond anticoagulation and developed for a wide range of clinical disorders. This article provides a "state of the art" review of our current understanding of the pharmacology of heparin and related drugs and an overview of the status of development of such drugs.

    Full Text Available Diabetic retinopathy (DR, the most common microvascular complication of diabetes mellitus, is estimated to be the leading cause of new blindness in the working population of developed countries. Primary interventions such as intensive glycemic control, strict blood pressure regulation, and lipid-modifying therapy as well as local ocular treatment (laser photocoagulation and pars plana vitrectomy can significantly reduce the risk of retinopathy occurrence and progression. Considering the limitations of current DR treatments development of new therapeutic strategies, it becomes necessary to focus on pharmacological treatment. Currently, there is increasing evidence that inflammatory processes have a considerable role in the pathogenesis of DR with multiple studies showing an association of various systemic as well as local (vitreous and aqueous fluid inflammatory factors and the progression of DR. Since inflammation is identified as a relevant mechanism, significant effort has been directed to the development of new concepts for the prevention and treatment of DR acting on the inflammatory processes and the use of pharmacological agents with anti-inflammatory effect. Inhibiting the inflammatory pathway could be an appealing treatment option for DR in future practices, and as further prospective randomized clinical trials accumulate data, the role and guidelines of anti-inflammatory pharmacologic treatments will become clearer.

    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

    Idiopathic pulmonary fibrosis (IPF) is a deadly disease with a median survival of approximately three years in historical cohorts. Despite increased knowledge of disease pathophysiology and selection of more targeted therapy, main clinical trials yielded negative results. However, two agents, pirfenidone and nintedanib, were recently shown to be effective in IPF and received marketing authorization worldwide. Both drugs significantly reduce functional decline and disease progression with an acceptable safety profile. Yet, none of these drugs actually improves or even stabilizes the disease or the symptoms perceived by the patient. Several other treatments and combinations are currently tested, and many more are ready for clinical trials. Their completion is critical for achieving the ultimate goal of curing patients with IPF.

  17. Pharmacological foundations of cardio-oncology.

    2010-07-01

    Anthracyclines and many other antitumor drugs induce cardiotoxicity that occurs "on treatment" or long after completing chemotherapy. Dose reductions limit the incidence of early cardiac events but not that of delayed sequelae, possibly indicating that any dose level of antitumor drugs would prime the heart to damage from sequential stressors. Drugs targeted at tumor-specific moieties raised hope for improving the cardiovascular safety of antitumor therapies; unfortunately, however, many such drugs proved unable to spare the heart, aggravated cardiotoxicity induced by anthracyclines, or were safe in selected patients of clinical trials but not in the general population. Cardio-oncology is the discipline aimed at monitoring the cardiovascular safety of antitumor therapies. Although popularly perceived as a clinical discipline that brings oncologists and cardiologists working together, cardio-oncology is in fact a pharmacology-oriented translational discipline. The cardiovascular performance of survivors of cancer will only improve if clinicians joined pharmacologists in the search for new predictive models of cardiotoxicity or mechanistic approaches to explain how a given drug might switch from causing systolic failure to inducing ischemia. The lifetime risk of cardiotoxicity from antitumor drugs needs to be reconciled with the identification of long-lasting pharmacological signatures that overlap with comorbidities. Research on targeted drugs should be reshaped to appreciate that the terminal ballistics of new "magic bullets" might involve cardiomyocytes as innocent bystanders. Finally, the concepts of prevention and treatment need to be tailored to the notion that late-onset cardiotoxicity builds on early asymptomatic cardiotoxicity. The heart of cardio-oncology rests with such pharmacological foundations. PMID:20335321

    As the most familiar type of arthritis and a chronic illness of the joints, Osteoarthritis (OA) affects a great number of people on the global scale. XuanHuSuo powder (XHSP), a conventional herbal formula from China, has been extensively applied in OA treatment. Nonetheless, its pharmacological mechanism has not been completely expounded. In this research, a network pharmacology approach has been chosen to study the pharmacological mechanism of XHSP on OA, and the pharmacology networks were established based on the relationship between four herbs found in XHSP, compound targets, and OA targets. The pathway enrichment analysis revealed that the significant bioprocess networks of XHSP on OA were regulation of inflammation, interleukin-1β (IL-1β) production and nitric oxide (NO) biosynthetic process, response to cytokine or estrogen stimuli, and antiapoptosis. These effects have not been reported previously. The comprehensive network pharmacology approach developed by our research has revealed, for the first time, a connection between four herbs found in XHSP, corresponding compound targets, and OA pathway systems that are conducive to expanding the clinical application of XHSP. The proposed network pharmacology approach could be a promising complementary method by which researchers might better evaluate multitarget or multicomponent drugs on a systematic level.

    2008-07-01

    A brief consultation and advice (BCA) approach to dealing with routine referrals was introduced into a child and adolescent mental health service (CAMHS) over an 18-month period. This is a time-limited, client-centred and solution-focused approach to dealing with common non-complex referrals. The model proposes that all families are seen for an initial \\'consultation\\' appointment followed by a maximum of two further appointments. A randomized controlled study compared the clinical effectiveness of BCA treatment with treatment as usual (TAU) over a 6-month period. The parents of children referred to CAMHS were eligible to participate if their child was deemed \\'non-complex\\'. Ethical approval was granted by the relevant ethics committee. Families who consented to participate in the study were randomly allocated to either the BCA or TAU group. Sixty children enrolled in the study. Both groups showed improvements on a number of variables at 3 months post treatment, but only those receiving BCA showed continued improvement at 6 months. Participants in both groups showed high levels of satisfaction with the treatment received. Participants in the TAU group expressed dissatisfaction with long waiting times and had a higher drop out rate than the BCA treatment group. During the time frame studied, the introduction of the BCA approach did not lead to a decrease in overall mean waiting time. These results and the usefulness of a BCA model are discussed.

  12. Pharmacology and toxicology of sensitizers: mechanism studies

    International Nuclear Information System (INIS)

    Nitroimidazoles are being studied extensively as hypoxic cell radiosensitizers. Besides their ability to selectively sensitize hypoxic cells to radiation, which depends on the parent compound, nitroimidazoles have a variety of other effects in vitro, in vivo and clinically which appear to require reductive metabolism. As a first step to suggesting possible mechanisms for these other biological effects, a summary has been made of the known oxidative and reductive products of the two most widely studied radiosensitizers, metronidazole and misonidazole. As a second step to suggesting possible mechanisms for these biological effects, it is important to view the problem in terms of the in vivo situation where distribution and sites of metabolism of the drug and its reduction products will be important factors. Combining basic information about the reduction chemistry of nitroimidazoles with knowledge about the pharmacology of drugs and their reduced products should allow a better assessment of mechanism of action as well as a better implementation of these drugs clinically

    2016-03-01

    The Second Insubria Autumn School on Neuroimmune Pharmacology was held at the University of Insubria in Varese (Italy) in November 16th-20th 2015, under the auspices of the Society on NeuroImmune Pharmacology, the Italian Society of Pharmacology, and the Italian Association for Neuroimmunology. The School was dedicated to the repurposing of established drugs for novel indications, considering the enormous opportunities for drug repositioning provided by the prominent innovative and interdisciplinary approaches peculiar to neuroimmune pharmacology. More than 40 graduate students and postdoctoral fellows from 12 european universities, research institutes and hospitals attended the School, and lectures were given by 20 internationally acknowledged experts in the fields of basic and clinical neurosciences, immunology, and pharmacology. A poster session provided young researchers the opportunity to present their results, and the best poster was given the Journal of Neuroimmune Pharmacology Young Investigator Award. PMID:26670166

  12. Multiple sclerosis: general features and pharmacologic approach

    International Nuclear Information System (INIS)

    Multiple sclerosis is an autoimmune, inflammatory and desmyelinization disease central nervous system (CNS) of unknown etiology and critical evolution. There different etiological hypotheses talking of a close interrelation among predisposing genetic factors and dissimilar environmental factors, able to give raise to autoimmune response at central nervous system level. Hypothesis of autoimmune pathogeny is based on study of experimental models, and findings in biopsies of affected patients by disease. Accumulative data report that the oxidative stress plays a main role in pathogenesis of multiple sclerosis. Oxygen reactive species generated by macrophages has been involved as mediators of demyelinization and of axon damage, in experimental autoimmune encephalomyelitis and strictly in multiple sclerosis. Disease diagnosis is difficult because of there is not a confirmatory unique test. Management of it covers the treatment of acute relapses, disease modification, and symptoms management. These features require an individualized approach, base on evolution of this affection, and tolerability of treatments. In addition to diet, among non-pharmacologic treatments for multiple sclerosis it is recommended physical therapy. Besides, some clinical assays have been performed in which we used natural extracts, nutrition supplements, and other agents with promising results. Pharmacology allowed neurologists with a broad array of proved effectiveness drugs; however, results of research laboratories in past years make probable that therapeutical possibilities increase notably in future.

    Advances in systems biology in conjunction with the expansion in knowledge of drug effects and diseases present an unprecedented opportunity to extend traditional pharmacokinetic and pharmacodynamic modeling/analysis to conduct systems pharmacology modeling. Many drugs that cause liver injury and myopathies have been studied extensively. Mitochondrion-centric systems pharmacology modeling is important since drug toxicity across a large number of pharmacological classes converges to mitochondrial injury and death. Approaches to systems pharmacology modeling of drug effects need to consider drug exposure, organelle and cellular phenotypes across all key cell types of human organs, organ-specific clinical biomarkers/phenotypes, gene-drug interaction and immune responses. Systems modeling approaches, that leverage the knowledge base constructed from curating a selected list of drugs across a wide range of pharmacological classes, will provide a critically needed blueprint for making informed decisions to reduce the rate of attrition for drugs in development and increase the number of drugs with an acceptable benefit/risk ratio.

    2014-01-01

    Anticoagulation for the prevention of stroke is an important aspect of the management of atrial fibrillation. Novel anticoagulants including oral factor Xa inhibitors rivaroxaban and apixaban and the direct thrombin inhibitor dabigatran have emerged as important therapeutic treatment options for prevention of stroke in non-valvular atrial fibrillation. These agents offer practical advantages over traditional vitamin K antagonists, however an understanding of their individual pharmacokinetic and other agent-specific differences is essential for identifying appropriate candidates for therapy, and for selecting the appropriate agent that will be effective and safe. Here, we review the pharmacokinetic process of oral medication use, summarize the newer anticoagulants, their pharmacology, individual pharmacokinetic features, and explore possible explanations for the differences in bleeding outcomes observed in the clinical trials.

    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.

    Kasashi, Kumiko

    2012-01-01

    When athletes consult sports outpatient or orthopedic clinics it is possible to undergo drug treatment with the medical staff having prior knowledge of that patient being an athlete. However, if athletes seek any other diagnosis and treatment as an ordinary patient, the possibility of medical staff realizing the potential for imposing a doping issue on the athlete is extremely low. As a result, if the athlete fails to provide medical staff with information regarding anti-doping regulations when receiving clinical treatment, drug treatment administered as part of medical practices could be viewed as doping, resulting in the athlete being disciplined. In order to avoid this, pharmacist should participate in training in order to be able to provide information for anti-doping purposes. It is my personal opinion that knowledge regarding anti-doping is something that should be shared by all pharmacists, as pharmacists are educated in the fields of pharmacology and pharmacokinetics during the pharmacy education process, and sports pharmacology is a part of this. However, in order for pharmacists to understand sports pharmacology, it is necessary to provide education not only on the benefits and adverse effects of pharmaceutical products, but also on the concept of banned substances. It can be considered one of the pharmacist's duties to protect athletes who purchase drugs at a pharmacy or consult medical institutions as patients. With this, I would like to propose considering the potential for introducing sports pharmacology to pharmaceutical education, and specialist pharmacist training in the sports spectrum.

    Data in the biological, chemical, and clinical domains are accumulating at ever-increasing rates and have the potential to accelerate and inform drug development in new ways. Challenges and opportunities now lie in developing analytic tools to transform these often complex and heterogeneous data into testable hypotheses and actionable insights. This is the aim of computational pharmacology, which uses in silico techniques to better understand and predict how drugs affect biological systems, which can in turn improve clinical use, avoid unwanted side effects, and guide selection and development of better treatments. One exciting application of computational pharmacology is drug repurposing-finding new uses for existing drugs. Already yielding many promising candidates, this strategy has the potential to improve the efficiency of the drug development process and reach patient populations with previously unmet needs such as those with rare diseases. While current techniques in computational pharmacology and drug repurposing often focus on just a single data modality such as gene expression or drug-target interactions, we argue that methods such as matrix factorization that can integrate data within and across diverse data types have the potential to improve predictive performance and provide a fuller picture of a drug's pharmacological action.

  10. Pharmacological potential of cerium oxidenanoparticles

    Celardo, Ivana; Pedersen, Jens Z.; Traversa, Enrico; Ghibelli, Lina

    2011-04-01

    Nanotechnology promises a revolution in pharmacology to improve or create ex novo therapies. Cerium oxidenanoparticles (nanoceria), well-known as catalysts, possess an astonishing pharmacological potential due to their antioxidant properties, deriving from a fraction of Ce3+ ions present in CeO2. These defects, compensated by oxygen vacancies, are enriched at the surface and therefore in nanosized particles. Reactions involving redox cycles between the Ce3+ and Ce4+oxidation states allow nanoceria to react catalytically with superoxide and hydrogen peroxide, mimicking the behavior of two key antioxidant enzymes, superoxide dismutase and catalase, potentially abating all noxious intracellularreactive oxygen species (ROS) via a self-regenerating mechanism. Hence nanoceria, apparently well tolerated by the organism, might fight chronic inflammation and the pathologies associated with oxidative stress, which include cancer and neurodegeneration. Here we review the biological effects of nanoceria as they emerge from in vitro and in vivo studies, considering biocompatibility and the peculiar antioxidant mechanisms.

    Treatment of eating disorders is difficult regardless of the methods employed. Pharmacologic management in anorexia nervosa and in bulimia nervosa is especially helpful when it is part of a multimodal treatment approach that includes individual, family and behavioral therapy. Care must be taken to guard against side effects, abuse and noncompliance in a group of patients that tends to be prone to all three. PMID:3284300

    Safety pharmacology (SP) is an essential part of the drug development process that aims to identify and predict adverse effects prior to clinical trials. SP studies are described in the International Conference on Harmonisation (ICH) S7A and S7B guidelines. The core battery and supplemental SP studies evaluate effects of a new chemical entity (NCE) at both anticipated therapeutic and supra-therapeutic exposures on major organ systems, including cardiovascular, central nervous, respiratory, renal and gastrointestinal. This review outlines the current practices and emerging concepts in SP studies including frontloading, parallel assessment of core battery studies, use of non-standard species, biomarkers, and combining toxicology and SP assessments. Integration of the newer approaches to routine SP studies may significantly enhance the scope of SP by refining and providing mechanistic insight to potential adverse effects associated with test compounds. - Highlights: • SP — mandatory non-clinical risk assessments performed during drug development. • SP organ system studies ensure the safety of clinical participants in FiH trials. • Frontloading in SP facilitates lead candidate drug selection. • Emerging trends: integrating SP-Toxicological endpoints; combined core battery tests.

  3. Atmospheric Release Advisory Capability

    International Nuclear Information System (INIS)

    The Atmospheric Release Advisory Capability (ARAC) project is a Department of Energy (DOE) sponsored real-time emergency response service available for use by both federal and state agencies in case of a potential or actual atmospheric release of nuclear material. The project, initiated in 1972, is currently evolving from the research and development phase to full operation. Plans are underway to expand the existing capability to continuous operation by 1984 and to establish a National ARAC Center (NARAC) by 1988. This report describes the ARAC system, its utilization during the past two years, and plans for its expansion during the next five to six years. An integral part of this expansion is due to a very important and crucial effort sponsored by the Defense Nuclear Agency to extend the ARAC service to approximately 45 Department of Defense (DOD) sites throughout the continental US over the next three years

  4. Payload advisory panel recommendations

    Science.gov (United States)

    Moore, Berrien, III

    1991-01-01

    The Payload Advisory Panel proposes a restructured Earth Observing System (EOS) mission to address high-priority science and environmental policy issues in Earth System Science. These issues have been identified through studies conducted by the Intergovernmental Panel on Climate Change (IPCC), the United States Environmental Protection Agency (EPA), and the Committee on Earth and Environmental Sciences (CEES). The restructured EOS defers efforts to improve the understanding of the middle and upper stratosphere and solid earth geophysics. The strategy of the mission combines high priority new measurements with continuation of critical data sets begun by missions which precede EOS. Collaborative arrangements with international partners are an essential part of the program and additional arrangements are posed. The need for continuity in Earth observations and the urgency of environmental questions require launch of some EOS elements as soon as possible. They further require maintenance of the EOS objective of obtaining consistent 15-year measurement records.

  10. Pharmacological targeting of Mdm2: Rationale and perspectives for radiosensitization

    International Nuclear Information System (INIS)

    The central role of p53 after exposure to ionizing radiation has been widely demonstrated. Mdm2, the main cellular regulator of p53, is a promising target for radiosensitizing purposes. In this article, we review the most recent data on the pharmacological targeting of Mdm2, with focus on strategies of radiosensitization. Antitumor activity of Mdm2 inhibitors has been related with activation of p53-dependant apoptosis, action on DNA repair systems, and anti-angiogenic activity. Preliminary data suggested a synergic interaction between Mdm2 inhibitors and ionizing radiations. However, no clinical data has been published yet on the pharmacological targeting of Mdm2. Given their new mechanisms of action, these new molecules should be subject to careful clinical assessment. Although promising, these strategies expose to unexpected toxicities. (authors)

    The pharmacokinetic and pharmacodynamic disciplines address pharmacological traits, including efficacy and adverse events. Pharmacogenomics studies have identified pervasive genetic effects on treatment outcomes, resulting in the development of genetic biomarkers for optimization of drug therapy. Pharmacogenomics-based tests are already being applied in clinical decision making. However, despite substantial progress in identifying the genetic etiology of pharmacological response, current biomarker panels still largely rely on single gene tests with a large portion of the genetic effects remaining to be discovered. Future research must account for the combined effects of multiple genetic variants, incorporate pathway-based approaches, explore gene-gene interactions and nonprotein coding functional genetic variants, extend studies across ancestral populations, and prioritize laboratory characterization of molecular mechanisms. Because genetic factors can play a key role in drug response, accurate biomarker tests capturing the main genetic factors determining treatment outcomes have substantial potential for improving individual clinical care.

  12. Pharmacological management of acute radiation morbidity

    Energy Technology Data Exchange (ETDEWEB)

    Zimmermann, J.S.; Kimmig, B. [Klinik fuer Strahlentherapie (Radioonkologie), Christian-Albrecht-Universitaet Kiel (Germany)

    1998-11-01

    Background: The acute radiation morbidity may be a serious problem for the patient and may be decreased by pharmacological approaches. Material and methods: A database research (Medline, Cancerlit, DIMDI, etc.) was performed in order to obtain pharmacological approaches to decrease the acute radiation morbidity. The evaluation was focused on therapeutic principles but not on special drugs. Results: Different approaches may be chosen to protect healthy tissues from the effects of ionizing radiation: 1. Administration of cyto- or radioprotective agents prior to irradiation, 2. administration of agents to avoid additional secondary toxicity by inflammation or superinfection during the treatment cycle (supportive care) and 3. administration of rescue agents, such as bone marrow CSFs or hyperbaric oxygen (HBO), after therapy. For radioprotection, there are reports on cellular protection by vitamine E, vitamine C, beta carotene, ribose-cysteine, glutamine, Mgcl2/adenosine triphosphate and WR-2721 (amifostine). In general, preclinical studies show that the combination of pretreatment with amifostine, irradiation, and G-CSF after radiation enhances hematologic recovery. Assessment of these combined effects, including local supportive therapies, merits further clinical investigation. There are data from prospective studies as well as from empirical clinical experience, that radioprotection and clinical supportive care may reduce the treatment related morbidity by 10 to 30% either. Conclusions: A further improvement of the therapeutic ratio is to be expected by systemically combined application of radioprotectors, supportive care and rescue agents. (orig.)

  13. Tinnitus: Network pathophysiology-network pharmacology

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Tinnitus, the phantom perception of sound, is a prevalent disorder. One in 10 adults has clinically significant subjective tinnitus, and for 1 in 100, tinnitus severely affects their quality of life. Despite the significant unmet clinical need for a safe and effective drug targeting tinnitus relief, there is currently not a single FDA-approved drug on the market. The search for drugs that target tinnitus is hampered by the lack of a deep knowledge of the underlying neural substrates of this pathology. Recent studies are increasingly demonstrating that, as described for other central nervous system disorders, tinnitus is a pathology of brain networks. The application of graph theoretical analysis to brain networks has recently provided new information concerning their topology, their robustness and their vulnerability to attacks. Moreover, the philosophy behind drug design and pharmacotherapy in central nervous system pathologies is changing from that of magic bullets that target individual chemoreceptors or disease-causing genes into that of magic shotguns, promiscuous or dirty drugs that target disease-causing networks, also known as network pharmacology. In the present work we provide some insight into how this knowledge could be applied to tinnitus pathophysiology and pharmacotherapy.

  14. Pharmacological approach to evaluate aerosol pulmonary deposition.

    Drug delivery to the lung in vivo may be assessed using pharmacokinetic or pharmacodynamic techniques. The choice of method depends on drug class specificities. Pharmacokinetic determination of deposition to the lung for drugs without hepatic first-pass effect, such as short acting beta2-agonists, has to be done shortly after inhalation to minimize the effect of gastrointestinal absorption. For medication undergoing important hepatic first-pass metabolisation, such as inhaled corticosteroid, plasma concentration indirectly reflects bronchial deposition. The pharmacodynamic profile should be assessed through clinical effects and adverse events induced by inhaled drugs. Dose ranking of lung deposition for bronchodilators requires patient selection with sufficient bronchial obstruction to maintain room for improvement after the first dose. To assess dose effect relationship between inhaled corticosteroid, the Finney parallel line bioassay is the reference method with a study period of at least 6 weeks. Analysis of side effects with high doses of beta2-agonists or inhaled corticosteroids may also be used to compare lung deposition. Finally, pharmacological evaluation of lung deposition provides complementary information to scintigraphic studies, based on their clinical relevance. PMID:15966772

    Problem-based learning (PBL) requires active student participation and the use of clinical cases as a trigger to learn within a given area. It has gained much attention as a pedagogic alternative in the course of reform in medica education due to information overload. From discipline-based consideration, it is interesting to understand the views of department heads of pharmacology about implementing PBL for their medical students. According to a general survey from the heads of the department of pharmacology across medical schools in Taiwan, we found that although serious reservation about the approach remains, many departments indeed look forward to including PBL component in their pharmacology curriculum.

    Brain aging and aging-related neurodegenerative disorders are major health challenges faced by modern societies. Brain aging is associated with cognitive and functional decline and represents the favourable background for the onset and development of dementia. Brain aging is associated with early and subtle anatomo-functional physiological changes that often precede the appearance of clinical signs of cognitive decline. Neuroimaging approaches unveiled the functional correlates of these alterations and helped in the identification of therapeutic targets that can be potentially useful in counteracting age-dependent cognitive decline. A growing body of evidence supports the notion that cognitive stimulation and aerobic training can preserve and enhance operational skills in elderly individuals as well as reduce the incidence of dementia. This review aims at providing an extensive and critical overview of the most recent data that support the efficacy of non-pharmacological and pharmacological interventions aimed at enhancing cognition and brain plasticity in healthy elderly individuals as well as delaying the cognitive decline associated with dementia.

    The keynote presentation of the Safety Pharmacology (SP) Society 9th Annual Meeting addressed the urgency, for pharmaceutical organizations, to implement strategies for effectively communicating drug risks to all concerned stakeholders and, in particular, the general public. The application of chronobiology to SP investigational protocols can improve the search of drug-induced adverse effects. The Distinguished Service Award Lecture reviewed a life-long journey through trials and tribulations in the quest of the ever-distant scientific truth. The revision process of Directive 86/609/EC for improving animal welfare should be conducted with the purpose of maintaining a fair balance among animal protection, human health and research imperatives in order to prevent the migration of pharmaceutical activities outside Europe. Additional topics of interest were the behavioral, metabolic and cardiovascular problems experienced by small animals housed at the standard laboratory temperature. A technology for the automated collection of blood and urine samples in rats implanted with telemetry sensors was presented. Non-clinical, clinical, regulatory and legal aspects of abuse liability were expertly reviewed. The 'degradability' of pharmaceuticals into environment-friendly chemicals should be an actively searched and optimized feature of future pharmaceuticals in order to prevent drug pollution of ecosystems. Transgenic and diseased animal models should be selected whenever they can facilitate the determination of drug-induced adverse effects. SP strategies to investigate the safety of drug combination products were exemplified and analyzed in depth. The future of SP was proposed to lie not in the performance of regulatory studies of pharmacodynamic nature but in developing and early applying an array of screening assays for clearing clinical candidates against known drug-induced organ function injuries. In conclusion, the 2009 SP Society annual meeting offered a wealth of

    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.

    Drug absorption in patients with chronic pancreatitis might be affected by the pathophysiology of the disease. The exocrine pancreatic insufficiency is associated with changes in gastrointestinal intraluminal pH, motility disorder, bacterial overgrowth and changed pancreatic gland secretion....... Together these factors can result in malabsorption and may also affect the efficacy of pharmacological intervention. The lifestyle of chronic pancreatitis patients may also contribute to gastrointestinal changes. Many patients limit their food intake because of the pain caused by eating and in some cases...... food intake is more or less substituted with alcohol, tobacco and coffee. Alcohol and drug interaction are known to influence the pharmacokinetics by altering either drug absorption or by affecting liver metabolism. Since patients suffering from chronic pancreatitis experience severe pain, opioids...

  5. Pharmacology of human experimental anxiety

    Directory of Open Access Journals (Sweden)

    F.G. Graeff

    2003-04-01

    Full Text Available This review covers the effect of drugs affecting anxiety using four psychological procedures for inducing experimental anxiety applied to healthy volunteers and patients with anxiety disorders. The first is aversive conditioning of the skin conductance responses to tones. The second is simulated public speaking, which consists of speaking in front of a video camera, with anxiety being measured with psychometric scales. The third is the Stroop Color-Word test, in which words naming colors are painted in the same or in a different shade, the incongruence generating a cognitive conflict. The last test is a human version of a thoroughly studied animal model of anxiety, fear-potentiated startle, in which the eye-blink reflex to a loud noise is recorded. The evidence reviewed led to the conclusion that the aversive conditioning and potentiated startle tests are based on classical conditioning of anticipatory anxiety. Their sensitivity to benzodiazepine anxiolytics suggests that these models generate an emotional state related to generalized anxiety disorder. On the other hand, the increase in anxiety determined by simulated public speaking is resistant to benzodiazepines and sensitive to drugs affecting serotonergic neurotransmission. This pharmacological profile, together with epidemiological evidence indicating its widespread prevalence, suggests that the emotional state generated by public speaking represents a species-specific response that may be related to social phobia and panic disorder. Because of scant pharmacological data, the status of the Stroop Color-Word test remains uncertain. In spite of ethical and economic constraints, human experimental anxiety constitutes a valuable tool for the study of the pathophysiology of anxiety disorders.

    Cognitive deficits in schizophrenia are a clinically relevant symptom dimension and one of the best predictors for functional outcome. Pharmacological treatment of cognitive deficits in schizophrenia is still a challenge. The objective of this article is to present a detailed review of the literature on strategies for the pharmacological treatment of cognitive deficits. It is not clear whether first-generation antipsychotics have a genuine positive influence on cognition. There is only sparse evidence for the positive effect of second-generation antipsychotics on cognitive processes. Furthermore it is not evident that second-generation antipsychotics are more beneficial than first-generation antipsychotics in the treatment of cognitive deficits. The add-on use of substances which directly influence cognitive processes, so-called cognition-enhancing drugs is more promising.

    Sabbag, Rony; Levin, Raz; Edelman, Shany; Heresco-Levy, Uriel

    2011-01-01

    Treatment for schizophrenia remains one of the major challenges of modern medicine. The development of innovative pharmacological approaches for this disorder can potentially alleviate tremendous human suffering and revolutionize mental health delivery systems. While current treatment guidelines for schizophrenia refer to the post-psychosis onset phase of illness, presently there is a strong resurgent interest in secondary prevention intervention applied during schizophrenia prodrome. This development stems largely from the recognition that neurobiological deficit processes associated with schizophrenia severity and chronicity are already active by the time clinical onset is recognized. Proposed preventive treatments include presently used medications and experimental compounds that hypothetically may influence ongoing pathophysiological processes earlier in their development. The future establishment of the early recognition and intervention concept in schizophrenia is critically dependent on the outcome of ongoing research assessing the feasibility of prodrome diagnosis, the efficacy of specific medications and the alleviation of the risks associated with early pharmacological treatment.

    2015-11-01

    Current medicines for the clinical management of inflammatory diseases act by inhibiting specific enzymes or antagonising specific receptors or blocking their ligands. In the past decade, a new paradigm in our understanding of the inflammatory process has emerged with the appreciation of genetic, molecular, and cellular mechanisms that are engaged to actively resolve inflammation. The 'resolution of acute inflammation' is enabled by counter-regulatory checkpoints to terminate the inflammatory reaction, promoting healing and repair. It may be possible to harness this knowledge for innovative approaches to the treatment of inflammatory pathologies. Here we discuss current translational attempts to develop agonists at proresolving targets as a strategy to rectify chronic inflammatory status. We reason this new approach will lead to the identification of better drugs that will establish a new branch of pharmacology, 'resolution pharmacology'.

    We reviewed the available pharmacological therapies for alcohol use disorder in Japan. For treatment of withdrawal delirium, therapists prefer to use antipsychotic drugs rather than benzodiazepines, which is different from other countries. Japan does not have any substantial treatment guidelines for withdrawal delirium. Therefore, so treatment strategies matching the environment of each facility need to be formulated. Moreover, current choices for prescribing anti-alcoholic drugs to cope with alcohol craving are limited to drugs such as cyanamide and disulfiram. However, the use of acamprosate has recently begun and a clinical trial for nalmefene is starting soon. We anticipate that these newer pharmacological therapies will contribute to better treatment of alcohol use disorder also in Japan.

    Withania somnifera, also called 'Indian ginseng', is an important medicinal plant of the Indian subcontinent. It is widely used, singly or in combination, with other herbs against many ailments in Indian Systems of Medicine since time immemorial. Withania somnifera contains a spectrum of diverse phytochemicals enabling it to have a broad range of biological implications. In preclinical studies, it has shown anti-microbial, anti-inflammatory, anti-tumor, anti-stress, neuroprotective, cardioprotective, and anti-diabetic properties. Additionally, it has demonstrated the ability to reduce reactive oxygen species, modulate mitochondrial function, regulate apoptosis, and reduce inflammation and enhance endothelial function. In view of these pharmacologic properties, W. somnifera is a potential drug candidate to treat various clinical conditions, particularly related to the nervous system. In this review, we summarize the pharmacologic characteristics and discuss the mechanisms of action and potential therapeutic applications of the plant and its active constituents.

    Full Text Available Echinacea purpurea (Asteraceae is a perennial medicinal herb with important immunostimulatory and anti-inflammatory properties, especially the alleviation of cold symptoms. The plant also attracted scientists′ attention to assess other aspects of its beneficial effects. For instance, antianxiety, antidepression, cytotoxicity, and antimutagenicity as induced by the plant have been revealed in various studies. The findings of the clinical trials are controversial in terms of side effects. While some studies revealed the beneficial effects of the plant on the patients and no severe adverse effects, some others have reported serious side effects including abdominal pain, angioedema, dyspnea, nausea, pruritus, rash, erythema, and urticaria. Other biological activities of the plant such as antioxidant, antibacterial, antiviral, and larvicidal activities have been reported in previous experimental studies. Different classes of secondary metabolites of the plant such as alkamides, caffeic acid derivatives, polysaccharides, and glycoproteins are believed to be biologically and pharmacologically active. Actually, concurrent determination and single analysis of cichoric acid and alkamides have been successfully developed mainly by using high-performance liquid chromatography (HPLC coupled with different detectors including UV spectrophotometric, coulometric electrochemical, and electrospray ionization mass spectrometric detectors. The results of the studies which were controversial revealed that in spite of major experiments successfully accomplished using E. purpurea, many questions remain unanswered and future investigations may aim for complete recognition of the plant′s mechanism of action using new, complementary methods.

  16. [Pharmacologic therapy of depression during pregnancy].

    The pregnancy is considered to be relatively high risk period for depressive episodes in women, particularly for those with pre-existing affective disorders. Epidemiological studies indicate that between 10% to 16% of pregnant women fulfil the diagnostic criteria for major depression and on average 20% is affected by an anxiety disorder. Pharmacological treatment of depression during pregnancy, however, brings with it certainties and dilemmas. It has been reported that untreated depression is associated with impaired feto-placental function, premature delivery, miscarriage, low fetal growth and perinatal unwanted effects. On the other hand, the use of antidepressant drugs in pregnancy might be at risk of major malformations (teratogenesis), neonatal toxicity, especially withdrawal symptoms and neuropsychological-behavioural impairment. In addition, the abrupt discontinuation of antidepressants, because of fear for adverse fetal effects, exposes women to serious clinical problems, in particular the disease relapse. A number of reviews indicates that among antidepressant drugs, the older SSRIs (in particular fluoxetine, sertraline, citalopram) seem to be avoided of teratogenic risks; for these reasons such drugs are nowadays considered of choice for the treatment of depression during pregnancy. Less information is available for other drugs, including triciclycs, venlafaxine, mirtazapine, bupropion, escitalopram and duloxetine. Withdrawal symptoms have been reported for all antidepressants; these symptoms, however, were self-limiting in majority of cases and had a favourable outcome. Inconclusive findings emerge, so far, from the few longitudinal studies focusing on the long-term neurodevelopment outcome in children.

    门冬氨酸鸟氨酸作为一种抗炎保肝药物广泛用于各种肝脏疾病的治疗,如肝性脑病、药物性肝损、脂肪肝、慢性肝炎等。除了三羧酸循环和鸟氨酸循环外,最新的研究显示,门冬氨酸鸟氨酸的抗炎作用可能与N-甲基-D-门冬氨酸(NMDA)受体有关。门冬氨酸鸟氨酸能够促进肝细胞修复,减轻肝脏炎性反应,降低肝细胞损害,临床疗效确切,而新的作用机制也具有进一步的研究价值。%L-ornithine-L-aspartate has been widely used as an anti-inflammatory and hepatoprotective drug in clinic, e.g. hepatic encephalopathy, drug-induced liver damage, fatty liver, chronic hepatitis, etc. Beside krebs cycle and ornithine cycle, recent research showed that the anti-inflammatory effect of L-ornithine-L-aspartate was associated with N-methyl-D-aspartate (NMDA) receptor. L-ornithine-L-aspartate could promote liver cell repair, decrease the liver inflammatory reaction, reduce the liver cell damage. The clinical curative effect is definite, the novel mechanism has also potential research value.

    Chronic heart failure is one of the leading causes for hospitalization in the United States and Europe, and is accompanied by high mortality. Current pharmacological therapy of chronic heart failure with reduced ejection fraction is largely based on compounds that inhibit the detrimental action of the adrenergic and the renin-angiotensin-aldosterone systems on the heart. More than one decade after spironolactone, two novel therapeutic principles have been added to the very recently released guidelines on heart failure therapy: the HCN-channel inhibitor ivabradine and the combined angiotensin and neprilysin inhibitor valsartan/sacubitril. New compounds that are in phase II or III clinical evaluation include novel non-steroidal mineralocorticoid receptor antagonists, guanylate cyclase activators or myosine activators. A variety of novel candidate targets have been identified and the availability of gene transfer has just begun to accelerate translation from basic science to clinical application. This review provides an overview of current pharmacology and pharmacotherapy in chronic heart failure at three stages: the updated clinical guidelines of the American Heart Association and the European Society of Cardiology, new drugs which are in clinical development, and finally innovative drug targets and their mechanisms in heart failure which are emerging from preclinical studies will be discussed.

    In a meta-analysis on controlled outcomes evaluations of 22,000 sex offenders, Losel and Schmucker found 80 comparisons between treatment and control groups. The recidivism rate averaged 19% in treated groups, and 27% in controls. Most other reviews reported a lower rate of sexual recidivism in treated sexual offenders. Of 2039 citations in this study (including literature in five languages), 60 studies held independent comparisons. Problematic issues included the control groups; various hormonal, surgical, cognitive behavioral, and psychotherapeutic treatments; and sample sizes. In the 80 studies compared after the year 2000, 32% were reported after 2000, 45% originated in the United States, 45% were reported in journals, and 36% were unpublished. Treatment characteristics showed a significant lack of pharmacologic treatment (7.5%), whereas use cognitive and classical behavioral therapy was 64%. In 68% of the studies, no information was available on the integrity of the treatment implementation; 36% of the treatment settings were outpatient only, 31% were prison settings, and 12% were mixed settings (prison, hospital, and outpatient). Integrating research interpretations is complicated by the heterogeneity of sex offenders, with only 56% being adult men and 17.5% adolescents. Offense types reported included 74% child molestation, 48% incest, and 30% exhibitionism. Pedophilia was not singled out. Follow-up periods varied from 12 months to greater than 84 months. The definition of recidivism ran the gamut from arrest (24%), conviction (30%), charges (19%), and no indication (16%). Results were difficult to interpret because of the methodological problems with this type of study. Overall, a positive outcome was noted with sex offender treatment. Cognitive-behavioral and hormonal treatment were the most promising. Voluntary treatment led to a slightly better outcome than mandatory participation. When accounting for a low base rate of sexual recidivism, the reduction

    Pharmacology in the traditional medical curriculum has been treated as a discrete "preclinical" discipline identifying itself distinctly different from the other preclinical sciences or clinical subjects in knowledge base as well as learning/teaching instructions. It is usually run in series with other pre-clinical courses (eg, anatomy, biochemistry,physiology etc), but in parallel with other paraclinical courses such as pathology, microbiology and community medicine. Clinical pharmacology was only introduced relatively recently designed to overcome the perceived deficiency in "preclinical" pharmacology regarding its therapeutic relevance and application to medicine. In many universities, both preclinical and clinical pharmacology courses co-exist, usually independently offered by two separate, sometimes non-interacting Departments of Pharmacology and Clinical Pharmacology. In this model,pharmacology is generally taught in a teacher-centered, discipline-oriented, and knowledge-based curriculum.Furthermore, pharmacology courses are commonly taught by "expert" teachers, who usually engage in excessiveteaching, often adopt a knowledge-based approach in both instruction and assessment, and frequently evade or ignore clinical relevance. The clinical relevance of the pharmacological sciences is sometimes also taught in a didactic and problem-solving manner, although it is usually case-oriented. In recent years, problem-based medical curricula have emerged, in varying forms, as a platform in which pharmacology is viewed as an integrated component in a holistic approach to medical education. In this problem-based learning (PBL) model, pharmacology is learned in a student-centered environment, based on self-directed, clinically relevant and case-oriented approach,usually in a small-group tutorial format. In PBL, pharmacology is learned in concert with other subject issues relevant to the case-problem in question, such as anatomy, physiology, pathology, microbiology

  18. Pharmacologic Agents for Chronic Diarrhea.

    Science.gov (United States)

    Lee, Kwang Jae

    2015-10-01

    Chronic diarrhea is usually associated with a number of non-infectious causes. When definitive treatment is unavailable, symptomatic drug therapy is indicated. Pharmacologic agents for chronic diarrhea include loperamide, 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists, diosmectite, cholestyramine, probiotics, antispasmodics, rifaximin, and anti-inflammatory agents. Loperamide, a synthetic opiate agonist, decreases peristaltic activity and inhibits secretion, resulting in the reduction of fluid and electrolyte loss and an increase in stool consistency. Cholestyramine is a bile acid sequestrant that is generally considered as the first-line treatment for bile acid diarrhea. 5-HT3 receptor antagonists have significant benefits in patients with irritable bowel syndrome (IBS) with diarrhea. Ramosetron improves stool consistency as well as global IBS symptoms. Probiotics may have a role in the prevention of antibiotic-associated diarrhea. However, data on the role of probiotics in the treatment of chronic diarrhea are lacking. Diosmectite, an absorbent, can be used for the treatment of chronic functional diarrhea, radiation-induced diarrhea, and chemotherapy-induced diarrhea. Antispasmodics including alverine citrate, mebeverine, otilonium bromide, and pinaverium bromide are used for relieving diarrheal symptoms and abdominal pain. Rifaximin can be effective for chronic diarrhea associated with IBS and small intestinal bacterial overgrowth. Budesonide is effective in both lymphocytic colitis and collagenous colitis. The efficacy of mesalazine in microscopic colitis is weak or remains uncertain. Considering their mechanisms of action, these agents should be prescribed properly.

    2015-01-01

    Biotechnology-derived pharmaceuticals or biopharmaceuticals (BPs) are molecules such as monoclonal antibodies, soluble/decoy receptors, hormones, enzymes, cytokines, and growth factors that are produced in various biological expression systems and are used to diagnose, treat, or prevent various diseases. Safety pharmacology (SP) assessment of BPs has evolved since the approval of the first BP (recombinant human insulin) in 1982. This evolution is ongoing and is informed by various international harmonization guidelines. Based on these guidelines, the potential undesirable effect of every drug candidate (small molecule or BP) on the cardiovascular, central nervous, and respiratory systems, referred to as the "core battery," should be assessed prior to first-in-human administration. However, SP assessment of BPs poses unique challenges such as choice of test species and integration of SP parameters into repeat-dose toxicity studies. This chapter reviews the evolution of SP assessment of BPs using the approval packages of marketed BPs and discusses the past, current, and new and upcoming approach and methods that can be used to generate high-quality data for the assessment of SP of BPs.
