    Bipolar affective disorder is a serious mental disease associated with significant morbidity and mortality. Good-quality research available to guide treatment strategies remains insufficient, particularly with regard to manic or hypomanic episodes. A critical review of the various stages of mania might be helpful for pharmaceutical companies and investigators as a prerequisite for the clinical evaluation of potential antimanic properties of medications. The main difficulty is with a comparison between anticonvulsants, antipsychotics, and mood stabilizers such as lithium (with equal efficacy in the acute phase and the prevention of recurrent manic episodes). No consensus has been reached with regard to the treatment of bouts of acute mania in various parts of the world. Controlled clinical trials have, at last, provided irrefutable evidence of the activity of lithium, which has long been used alone, as well as that of divalproate or its derivatives and, to a lesser extent, carbamazepine. The new antipsychotic agents have more recently established their efficacy, especially aripiprazole, asenapine, quetiapine; olanzapine, risperidone, and ziprasidone (not sure where the paradox is). In Europe, haloperidol is still the reference substance used in clinical trials despite the fact that it is not officially indicated in the treatment of mania. In the USA, lithium, divalproate, or antipsychotics can be prescribed as first-line treatment. In Europe, lithium remains the first-line medication, whereas divalproate and atypical antipsychotic agents are used only as second-line therapy. Although both types of medication (antipsychotics, normothymic agents, and/or anticonvulsants) have proved to be clinically effective in the management of mania by reducing the mania scores overall, the same does not apply, however, to all symptoms of mania. Factorial approaches to mania have all shown that since there are several clinical forms of mania, several clusters of manic symptoms can

    Full Text Available Research on assessing craving in laboratory settings often involves inducing and then measuring craving in subjects. Cue-induced craving is studied in laboratory settings using the cue reactivity paradigm, in which drug-related photos, videos, evocative scripts, olfactory cues, and paraphernalia may induce craving. Cue-induced craving evoked by drug-related stimuli could be associated with relapse and recurrence of drug addiction. In this article, the authors review different methods of assessing craving in laboratory settings and explain how human laboratory settings can bridge the gap between randomized clinical trials (RCTs and animal models on pharmacological treatments for drug dependence. The brief reviewed literature provides strong evidence that laboratory-based studies of craving may improve our understanding of how subjective reports of drug craving are related to objective measures of drug abuse and laboratory settings provide an opportunity to measure the degree to which they co-vary during pharmacological interventions. This issue has important implications inclinical studies.

    Objective To develop and validate an instrument to assess adherence to each individual drug taken by patients undergoing long-term treatment. Design Multicentre prospective observational validation study. Setting Six general practitioners' clinics and 6 university hospitals in Paris, France. Participants Patients 18 years and older receiving at least one long-term treatment. Methods The instrument was developed from a literature search and interviews with experts. Clarity and wording were assessed during pilot testing with 51 patients. The tool was validated in a sample of consecutive patients. We assessed agreement between adherence measured with our tool and drug diaries and compared measurements from our instrument with (1) the Lu instrument; (2) the Adherence Estimator (AE); (3) patient's adherence assessed by physicians; (4) the Morisky Medication Adherence Scale-4 items (MMAS-4); and (5) the Treatment Burden Questionnaire (TBQ). Reliability was assessed by a test–retest method. Results A total of 243 patients taking 961 drugs were recruited in 2014. We found good agreement between adherence measured by our tool and drug diaries (intraclass correlation coefficient (ICC) 0.69, 95% CI 0.34 to 0.91) and a linear relationship between measurement with our tool and (1) the Lu instrument (p<0.01); (2) 2 items of the AE (perceived need for medication (p<0.01) and concerns about medication (p<0.01)); (3) patients' adherence assessed by their physicians (p<0.01); (4) the MMAS-4 (p<0.01) and (5) the TBQ (p<0.01). Reliability of the retest was good (ICC 0.67, 95% CI 0.42 to 0.85). Conclusions We developed an instrument with acceptable validity and reliability to assess adherence for each drug taken by patients, usable in hospital and primary care settings. PMID:27165645

    At the beginning of 2011, the early benefit assessment of new drugs was introduced in Germany with the Act on the Reform of the Market for Medicinal Products (AMNOG). The Federal Joint Committee (G-BA) generally commissions the Institute for Quality and Efficiency in Health Care (IQWiG) with this type of assessment, which examines whether a new drug shows an added benefit (a positive patient-relevant treatment effect) over the current standard therapy. IQWiG is required to assess the extent of added benefit on the basis of a dossier submitted by the pharmaceutical company responsible. In this context, IQWiG was faced with the task of developing a transparent and plausible approach for operationalizing how to determine the extent of added benefit. In the case of an added benefit, the law specifies three main extent categories (minor, considerable, major). To restrict value judgements to a minimum in the first stage of the assessment process, an explicit and abstract operationalization was needed. The present paper is limited to the situation of binary data (analysis of 2 × 2 tables), using the relative risk as an effect measure. For the treatment effect to be classified as a minor, considerable, or major added benefit, the methodological approach stipulates that the (two-sided) 95% confidence interval of the effect must exceed a specified distance to the zero effect. In summary, we assume that our approach provides a robust, transparent, and thus predictable foundation to determine minor, considerable, and major treatment effects on binary outcomes in the early benefit assessment of new drugs in Germany. After a decision on the added benefit of a new drug by G-BA, the classification of added benefit is used to inform pricing negotiations between the umbrella organization of statutory health insurance and the pharmaceutical companies.

    2016-07-01

    The Food and Drug Administration issued guidance for evaluating the cardiovascular risk of new diabetes mellitus drugs in 2008. Accumulating evidence from several completed trials conducted within this framework raises questions as to whether requiring safety outcome studies for all new diabetes mellitus therapies remains justified. Given the burden of cardiovascular disease in patients with diabetes, the focus should shift towards cardiovascular outcome studies designed to evaluate efficacy (i.e. to determine the efficacy of a drug over placebo or standard care) rather than demonstrating that risk is not increased by a pre-specified safety margin. All stakeholders are responsible for ensuring that new drug approvals occur under conditions of appropriate safety and effectiveness. It is also a shared responsibility to avoid unnecessary hurdles that may compromise access to useful drugs and threaten the sustainability of health systems. It is critical to renew this debate so that stakeholders can collectively determine the optimal approach for developing new drugs to treat type 2 diabetes mellitus. PMID:27418973

    Evidence linking alcohol and other drug abuse with child maltreatment, particularly neglect, is strong. But does substance abuse cause maltreatment? According to Mark Testa and Brenda Smith, such co-occurring risk factors as parental depression, social isolation, homelessness, or domestic violence may be more directly responsible than substance abuse itself for maltreatment. Interventions to prevent substance abuse-related maltreatment, say the authors, must attend to the underlying direct causes of both. Research on whether prevention programs reduce drug abuse or help parents control substance use and improve their parenting has had mixed results, at best. The evidence raises questions generally about the effectiveness of substance abuse services in preventing child maltreatment. Such services, for example, raise only marginally the rates at which parents are reunified with children who have been placed in foster care. The primary reason for the mixed findings, say Testa and Smith, is that almost all the parents face not only substance abuse problems but the co-occurring issues as well. To prevent recurring maltreatment and promote reunification, programs must ensure client progress in all problem areas. At some point in the intervention process, say Testa and Smith, attention must turn to the child's permanency needs and well-being. The best evidence to date suggests that substance-abusing parents pose no greater risk to their children than do parents of other children taken into child protective custody. It may be sensible, say the authors, to set a six-month timetable for parents to engage in treatment and allow twelve to eighteen months for them to show sufficient progress in all identified problem areas. After that, permanency plans should be expedited to place the child with a relative caregiver or in an adoptive home. Investing in parental recovery from substance abuse and dependence, the authors conclude, should not substitute for a comprehensive approach

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Abstract Background Less is known about mass drug administration [MDA] for neglected tropical diseases [NTDs] than is suggested by those so vigorously promoting expansion of the approach. This paper fills an important gap: it draws upon local level research to examine the roll out of treatment for two NTDs, schistosomiasis and soil-transmitted helminths, in Uganda. Methods Ethnographic research was undertaken over a period of four years between 2005-2009 in north-west and south-east Uganda. In addition to participant observation, survey data recording self-reported take-up of drugs for schistosomiasis, soil-transmitted helminths and, where relevant, lymphatic filariasis and onchocerciasis was collected from a random sample of at least 10% of households at study locations. Data recording the take-up of drugs in Ministry of Health registers for NTDs were analysed in the light of these ethnographic and social survey data. Results The comparative analysis of the take-up of drugs among adults revealed that although most long term residents have been offered treatment at least once since 2004, the actual take up of drugs for schistosomiasis and soil-transmitted helminths varies considerably from one district to another and often also within districts. The specific reasons why MDA succeeds in some locations and falters in others relates to local dynamics. Issues such as population movement across borders, changing food supply, relations between drug distributors and targeted groups, rumours and conspiracy theories about the 'real' purpose of treatment, subjective experiences of side effects from treatment, alternative understandings of affliction, responses to social control measures and historical experiences of public health control measures, can all make a huge difference. The paper highlights the need to adapt MDA to local circumstances. It also points to specific generalisable issues, notably with respect to health education, drug distribution and

  5. [Drug-drug interactions in antirheumatic treatment].

    Krüger, K

    2012-04-01

    Clinically relevant drug-drug interactions contribute considerably to potentially dangerous drug side-effects and are frequently the reason for hospitalization. Nevertheless they are often overlooked in daily practice. For most antirheumatic drugs a vast number of interactions have been described but only a minority with clinical relevance. Several potentially important drug interactions exist for non-steroidal anti-inflammatory drugs (NSAIDs), methotrexate, azathioprine, mycophenolate-mofetil and especially for cyclosporin A. Most importantly co-medication with methotrexate and sulfmethoxazole trimethoprim as well as azathioprine and allopurinol carries the risk of severe, sometimes life-threatening consequences. Nevertheless, besides these well-known high-risk combinations in each case of polypharmacy with antirheumatic drugs it is necessary to bear in mind the possibility of drug interactions. As polypharmacy is a common therapeutic practice in older patients with rheumatic diseases, they are at special risk. PMID:22527215

  6. Drug treatment of poststroke aphasia.

    Bakheit, A M O

    2004-03-01

    Impairment of language function (aphasia) is one of the most common neurological symptoms after stroke. Approximately one in every three patients who have an acute stroke will suffer from aphasia. The estimated incidence and prevalence of stroke in Western Europe is 140 and 800 per 100,000 of the population. Aphasia often results in significant disability and handicap. It is a major obstacle for patients to live independently in the community. When recovery from aphasia occurs, it is usually incomplete and patients are rarely able to return to full employment and other social activities. Currently, the main treatment for aphasia is conventional speech and language therapy. However, the effectiveness of this intervention has not been conclusively demonstrated and empirical observations suggest that spontaneous biological recovery may explain most of the improvement in language function that occurs in aphasics. The generally poor prognosis of the severe forms of poststroke language impairment (Broca, Wernicke and global aphasia), coupled with the limited effectiveness of conventional speech and language therapy has stimulated the search for other treatments that may be used in conjunction with speech and language therapy, including the use of various drugs. Dopamine agonists, piracetam (Nootropil), amphetamines, and more recently donepezil (Aricept), have been used in the treatment of aphasia in both the acute and chronic phase. The justification for the use of drugs in the treatment of aphasia is based on two types of evidence. Some drugs, such as dextroamphetamine (Dexedrine), improve attention span and enhance learning and memory. Learning is an essential mechanism for the acquisition of new motor and cognitive skills, and hence, for recovery from aphasia. Second, laboratory and clinical data suggest that drug treatment may partially restore the metabolic function in the ischemic zone that surrounds the brain lesion and also has a neuroprotective effect following

    2013-12-01

    Before medicines can be marketed in the UK, they are subject to a system of licensing and the granting of a marketing authorisation that describes the conditions and patient groups for which the medicinal product can be used within the terms of its licence.(1) The licensing process involves an assessment of data relating to the efficacy, safety and quality of the product. However, the marketing authorisation does not determine whether, or how, it will be used in clinical practice. In the UK, the National Institute for Health and Care Excellence (NICE), the Scottish Medicines Consortium (SMC) and the All Wales Medicines Strategy Group (AWMSG) publish recommendations on the use of medicines for health services in the United Kingdom. In this article we review their remit, work processes and the status of guidance published in England, Scotland, Wales and Northern Ireland. PMID:24336496

    2012-08-01

    Prisons inmates have high rates of substance abuse and associated social and health problems, and a concomitant high need for drug treatment while incarcerated. Female inmates have an even greater treatment need, yet most inmates do not participate in treatment while incarcerated. Using data from a nationally representative sample of prison inmates, this article examines the impact of gender on prison treatment participation and gender differences in the factors associated with clinical treatment participation. Females were significantly more likely to participate in prison drug treatment than males, controlling for other factors. For both males and females, severity of drug problems predicted participation in treatment. For males but not females, race was associated with prison treatment participation, and among those with drug abuse or dependence, females with co-occurring mental health problems were more likely to participate in treatment. Implications for prison assessment and treatment policies, and future research, are discussed. PMID:21764764

    Tuberculosis is an airborne infectious disease treated with combination therapeutic regimens. Adherence to long-term antituberculosis therapy is crucial for maintaining adequate blood drug level. The emergence and spread of drug-resistant Mycobacterium tuberculosis strains are mainly favored by the inadequate medical management of the patients. The therapeutic approach for drug-resistant tuberculosis is cumbersome, because of the poor, expensive, less-effective, and toxic alternatives to the first-line drugs. New antituberculosis drugs (bedaquiline and delamanid) have been recently approved by the health authorities, but they cannot represent the definitive solution to the clinical management of drug-resistant tuberculosis forms, particularly in intermediate economy settings where the prevalence of drug resistance is high (China, India, and former Soviet Union countries). New research and development activities are urgently needed. Public health policies are required to preserve the new and old therapeutic options. PMID:25573773

    Full Text Available Objectives: to evaluate the agreement between Visual Analogue Scales (VAS and numerical questions as a way of assessing the perception of teratogenic risk of treatment with drugs and radiotherapy. Methods: the sample comprised 144 pregnant and 143 non-pregnant women consecutively recruited at public health centers in Porto Alegre, in the State of Rio Grande do Sul, from February to August 2011. The perception of risk for congenital malformations in the general population and the perceptions of teratogenic risk for exposure to acetaminophen, meto-clopramide, misoprostol and radiotherapy were measured using VAS and numerical questions. The agreement between the results of the two techniques was tested using a Bland-Altman plot. Results: the medians for the perceptions measured using VAS were higher than those obtained using numerical questions for all variables. The perception of risk for acetaminophen showed the lower bias of the two techniques (bias=13.17; p<0.001 and exposure to radiotherapy, the higher (bias=25.02; p<0.001. Conclusion: there was no agreement between the measurements obtained using the two techniques for any of the risk perceptions under study. Risk perceptions were higher using VAS, for all kinds of exposure. Studies should be conducted to assess whether there is overestimation in other situations and social contexts owing to the use of VAS.

  15. Drug Treatment as a Crime Fighting Tool.

    BACKGROUND: The primary approach to reducing crime in the US has been through the criminal justice system. However, drug treatment may be an effective tool in reducing crime. In order to make better use of treatment as an alternative approach, one needs to know if reducing drug use through treatment results in decreased crime. AIMS OF THE STUDY: The objective of this paper is to model and empirically investigate the extent to which a change in drug use that results from treatment reduces crime and whether a change in drug use is causally related to change in crime. We focus on crime-for-profit. METHODS: We use a multi-site dataset of 3,502 inner-city drug users entering treatment. We analyze the change in drug use and crime pre and post treatment. We take first differences to address the omitted variable problem. RESULTS: We find that treatment reduces drug use and that, in turn, reduced drug use has a significant impact on crime. For our study population, reduced drug use seems to be causally related to reduced crime. This finding is robust to specification and subsamples. We estimate that reduced drug use due to treatment is associated with 54% fewer days of crime for profit, ceteris paribus. DISCUSSION: We use a longitudinal data set and a novel approach to analyze the relationship between crime and drugs. We analyze a low-income, inner-city, drug-addicted sample. We use self-reported crime. For our purposes, the use of individual data is an improvement over the use of aggregate level data that has been used in much of the related literature. Limitations of our paper include that we do not have a random sample and that our measure is self-reported in the previous 30 days. IMPLICATIONS FOR HEALTH POLICIES: Our findings suggest that drug treatment may be an effective crime-fighting tool. Treatment reduces not only the crime of drug possession, but also crime-for-profit. Current public policy emphasizes use of the criminal justice system, incarceration in

    New effective drugs for the treatment of tuberculosis (TB) are necessary for two main reasons: firstly, it would be desirable to reduce the duration of TB treatment from 6 to 4 months and secondly, new drugs are urgently needed for the treatment of multidrug-resistant strains of Mycobacterium tuberculosis. For the first time since 1960 the two new drugs bedaquiline and delamanid were approved and licensed in 2014 for the treatment of multidrug-resistant M. tuberculosis; however, efforts to reduce the duration of treatment to 4 months using fluoroquinolones have not been successful. Further new drugs are currently in phase 2 and phase 3 studies; therefore, new treatment options can be expected within the next few years. PMID:26787496

Many markets produce nonproprietary medicines; assessing their efficacy and safety is difficult as regulators may approve nonproprietary drugs without bioequivalence data, genotoxic evaluation, or risk management plans (RMPs. This assessment is especially important for fingolimod given its solubility/bioavailability profile, genotoxicity risk, and low-dose final product (0.5 mg. This paper presents an evaluation of the quality of proprietary and nonproprietary fingolimod variants.Methods: Proprietary fingolimod was used as a reference substance against which eleven nonproprietary fingolimod copies were assessed. The microparticle size distribution of each compound was assessed by laser light diffraction, and inorganic impurity content by sulfated ash testing. Heavy metals content was quantified using inductively coupled plasma optical emission spectrometry, and levels of unspecified impurities by high-performance liquid chromatography. Solubility was assessed in a range of solvents at different pH values. Key information from the fingolimod RMP is also presented.Results: Nonproprietary fingolimod variants exhibited properties out of proprietary or internationally accepted specifications, including differences in particle size distribution and levels of impurities such as heavy metals.

  20. Assessing Specificity of Anticancer Drugs In Vitro.

    2016-01-01

    A procedure for assessing specificity of anticancer drugs in vitro using cultures containing both tumor and non-tumor cells is demonstrated. The key element is the quantitative determination of a tumor-specific genetic alteration in relation to a universal sequence using a dual-probe digital PCR assay and the subsequent calculation of the proportion of tumor cells. The assay is carried out on a culture containing tumor cells of an established line and spiked-in non-tumor cells. The mixed culture is treated with a test drug at various concentrations. After the treatment, DNA is prepared directly from the survived adhesive cells in wells of 96-well plates using a simple and inexpensive method, and subjected to a dual-probe digital PCR assay for measuring a tumor-specific genetic alteration and a reference universal sequence. In the present demonstration, a heterozygous deletion of the NF1 gene is used as the tumor-specific genetic alteration and a RPP30 gene as the reference gene. Using the ratio NF1/RPP30, the proportion of tumor cells was calculated. Since the dose-dependent change of the proportion of tumor cells provides an in vitro indication for specificity of the drug, this genetic and cell-based in vitro assay will likely have application potential in drug discovery. Furthermore, for personalized cancer-care, this genetic- and cell-based tool may contribute to optimizing adjuvant chemotherapy by means of testing efficacy and specificity of candidate drugs using primary cultures of individual tumors.

    Symptomatic improvement of patients with functional dyspepsia after drug therapy is often incomplete and obtained in not more than 60% of patients. This is likely because functional dyspepsia is a heterogeneous disease.Although great advance has been achieved with the consensus definitions of the Rome Ⅰ and Ⅱ criteria, there are still some aspects about the definition of functional dyspepsia that require clarification. The Rome criteria explicitly recognise that epigastric pain or discomfort must be the predominant complaint in patients labelled as suffering from functional dyspepsia. However, this strict definition can create problems in the daily primary care clinical practice, where the patient with functional dyspepsia presents with multiple symptoms. Before starting drug therapy it is recommended to provide the patient with an explanation of the disease process and reassurance. A thorough physical examination and judicious use of laboratory data and endoscopy are also indicated. In general, the approach to treat patients with functional dyspepsia based on their main symptom is practical and effective. Generally, patients should be treated with acid suppressive therapy using proton-pump inhibitors if the predominant symptoms are epigastric pain or gastroesophageal reflux symptoms. Although the role of Helicobacter pylori(H pylori) in functional dyspepsia continues to be a matter of debate, recent data indicate that there is modest but clear benefit of eradication of H pylori in patients with functional dyspepsia. In addition,H pylori is a gastric carcinogen arid if found it should be eliminated. Although there are no specific diets for patients with FD, it may be helpful to guide the patients on healthy exercise and eating habits.

    makes them quit the treatment. From these problems emerges the need for development of effective new drugs, with smaller duration of therapy, less side effects and without the problem of resistance. After a long period such as 40 years, a new drug molecule bedaquiline was approved in December 2012 by FDA while the drug was in phase II research. Bedaquiline will be used in multidrug resistant tuberculosis therapy. When the chemical structures of bedaquilline and other candidate drugs were examined, the structures such as diarylquinoline, oxazolidinone, nitroimidazole, ethylenediamine drew attention. These common structures will be directive in designing new molecules. In this review, bedaquiline and other candidate drug molecules such as sutezolide, linezolide, PA-824, delamanide, rifapentine, gatifloxacin, moxifloxacin, BTZ-043, TBA-354, CPZEN-45, DC-159a, Q201, SQ-609, SQ-641 were mentioned.

    The aim of this study is to verify the level of transmission of lymphatic filariasis three years after stopping mass drug treatment in the 7 endemic districts in Togo. The survey was conducted in 2012 in Togo's 7 endemic districts grouped into four evaluation units (EU) using the WHO-recommended transmission assessment survey (TAS) protocol. Children aged 6-7 years were screened for Wuchereria bancofti antigen using the immunochromatographic card (ICT) method. A cluster sampling method was used to select eligible children in schools as the net primary-school enrolment ratio is greater than or equal to 75% in each of the four EUs. The number of children and schools to be selected in each EU, the randomization list for the selection of these children and the critical cut-off number of positive cases not to exceed were automatically generated using the Survey Sample Builder (SSB) tool, (NTD Support Center, Atlanta, Ga, USA). For confirmation, positive cases were subsequently tested for microfilaremia using nocturnal thick blood smear and for filarial antigen using Og4C3 antigen ELISA (TropBio ELISA Kit®, Townsville, Queensland, Australia). An EU is considered to have passed the test successfully (it is assumed that transmission can no longer be sustained), when the number of positive cases is below the critical cut-off number set by the SSB, which is roughly equivalent to 2% prevalence. Of the 1 706 children surveyed in Kpendjal-Tone's EU, 1 549 in Binah-Doufelgou's EU, 1 550 in Kozah's EU and the 1 575 in Amou-Haho's EU, 8 (0.46%), 1 (0.08%), 0 (0.00%) and 4 (0.25%) ICT positive cases respectively were detected. The number of positive ICT tests was well below 18, the critical cut number for each of the 4 EUs. All 13 ICT positive cases tested negative for nocturnal microfilaremia and Og4C3 ELISA. We conclude that all four EU passed the TAS with success, and the transmission of Wuchereria bancrofti is no longer likely to be sustained in the 7 endemic districts in Togo

    Tuberculosis (TB) remains a major global health problem as it is the second leading cause of death from an infectious disease worldwide, after the human immunodeficiency virus (HIV). Conventional treatments fail either because of poor patient compliance to the drug regimen or due to the emergence of multidrug-resistant tuberculosis. The aim of this review is to give an update on the information available on tuberculosis, its pathogenesis and current antitubercular chemotherapies. Direct lung delivery of anti-TB drugs using pulmonary delivery systems is then reviewed since it appears as an interesting strategy to improve first and second line drugs. A particular focus is place on research performed on inhalable dry powder formulations of antitubercular drugs to target alveolar macrophages where the bacteria develop. Numerous studies show that anti-TB drugs can be incorporated into liposomes, microparticles or nanoparticles which can be delivered as dry powders to the deep lungs for instantaneous, targeted and/or controlled release. Treatments of infected animals show a significant reduction of the number of viable bacteria as well as a decrease in tissue damage. These new formulations appear as interesting alternatives to deliver directly drugs to the lungs and favor efficient TB treatment. PMID:25499020

Failure of current therapy is attributed to a long duration of treatment leading to nonadherence and irregular therapy, lack of patient education about the disease, poverty, irregular supply by care providers, drug–drug interactions in patients coinfected with human immunodeficiency virus (HIV, inadequate regulations causing market overlap and irresponsible drug usage in the private sector, and lack of research, with no addition of new drugs in the last four decades. Present standards of care for the treatment of drug-susceptible tuberculosis, multidrug-resistant tuberculosis, tuberculosis-HIV coinfection, and latent tuberculosis infection are all unsatisfactory. Since 2000, the World Health Organization (WHO has focused on drug development for tuberculosis, as well as research in all relevant aspects to discover new regimens by 2015 and to eliminate tuberculosis as a public health concern by 2050. As a result, some 20 promising compounds from 14 groups of drugs have been discovered. Twelve candidates from eight classes are currently being evaluated in clinical trials. Ongoing research should prioritize identification of novel targets and newer application of existing drugs, discovery of multitargeted drugs from natural compounds, strengthening host factors by immunopotentiation with herbal immunomodulators, as well as protective vaccines before and after exposure, consideration of surgical measures when indicated, development of tools for rapid diagnosis, early identification of resistant strains, and

    2015-09-01

    In Japan, synthetic drugs have emerged since late 2000s, and cases of emergency visits and fatal traffic accidents due to acute intoxication have rapidly increased. The synthetic drugs gained popularity mainly because they were cheap and thought to be "legal". The Japanese government restricted not only production and distribution, but also its possession and use in April 2014. As the synthetic drug dependent patients have better social profiles compared to methamphetamine abusers, this legal sanction may have triggered the decrease in the number of synthetic drug dependent patient visits observed at Kanagawa Psychiatric Center since July 2014. Treatment of the synthetic drug dependent patients should begin with empathic inquiry into the motives and positive psychological effects of the drug use. In the maintenance phase, training patients to trust others and express their hidden negative emotions through verbal communications is essential. The recovery is a process of understanding the relationship between psychological isolation and drug abuse, and gaining trust in others to cope with negative emotions that the patients inevitably would face in their subsequent lives.

    2001-01-01

    Lithium has been the backbone of treatment for bipolar disorder for several decades, although recent advances have identified a number of other medications that have efficacy in treating various phases of the illness. These include the antiepileptic drugs valproate semisodium (divalproex sodium) and carbamazepine and some new antiepileptic drugs (e.g. lamotrigine and topiramate), and the atypical antipsychotics (e.g. olanzapine, clozapine and risperidone). Conventional antipsychotics continue to be used frequently in bipolar disorder, although they may be somewhat less effective than other treatments. Otherwise, to date, none of these treatments have been shown to be consistently more effective than any other, so that drug adverse effects and tolerability often dictate which agents are used in an individual patient. Drugs commonly used for the treatment of bipolar disorder are generally tolerated by most patients in large samples. However, the unique adverse effect signature of a drug will often suggest that it will be less tolerable in some patients than in others. Identifying a specific treatment for a specific patient requires a careful individualised assessment of the risk of adverse effects for that patient's unique circumstances. PMID:11580309

    Cancer is a complex disease since it is adaptive in such a way that it can promote proliferation and invasion by means of an overactive cell cycle and in turn cellular division which is targeted by antimitotic drugs that are highly validated chemotherapy agents. However, antimitotic drug cytotoxicity to non-tumorigenic cells and multiple cancer resistance developed in response to drugs such as taxanes and vinca alkaloids are obstacles faced in both the clinical and basic research field to date. In this review, the classes of antimitotic compounds, their mechanisms of action and cancer cell resistance to chemotherapy and other limitations of current antimitotic compounds are highlighted, as well as the potential of novel 17-β estradiol analogs as cancer treatment.

Our study aimed to investigate patterns of pre-treatment drug abuse, addiction treatment history and characteristics of patients in MMT in Tehran. Methods We applied a stratified cluster random sampling technique and conducted a cross-sectional survey utilizing a standard patient characteristic and addiction history form with patients (n = 810 in MMT. The Chi-square test and t-test served for statistical analyses. Results A clear majority of the participants were men (96%, more than 60% of whom were between 25 and 44 years of age, educated (89% had more than elementary education, and employed (>70%. The most commonly reported main drugs of abuse prior to MMT entry were opium (69% and crystalline heroin (24%. The patients’ lifetime drug experience included opium (92%, crystalline heroin (28%, cannabis (16%, amphetamines (15%, and other drugs (33%. Crystalline heroin abusers were younger than opium users, had begun abusing drugs earlier, and reported a shorter history of opiate addiction. Conclusion Opium and crystalline heroin were the main drugs of abuse. A high rate of addiction using more dangerous opiate drugs such as crystalline heroin calls for more preventive efforts, especially among young men.

The outbreak of cryptosporidiosis which occurred in Milwaukee in 1993 was not only the first significant emergence of Cryptosporidium spp. as a major human pathogen but also a huge waterborne outbreak thickening thousands of people from a major city in North America. Since then, outbreaks of cryptosporidiosis are regularly occurring throughout the world. New drugs against this parasite became consequently urgently needed. Among the most commonly used treatments against cryptosporidiosis are paromomycin, and azithromycin, which are partially effective. Nitazoxanide (NTZ’s effectiveness was demonstrated in vitro, and in vivo using several animal models and finally in clinical trials. It significantly shortened the duration of diarrhea and decreased mortality in adults and in malnourished children. NTZ is not effective without an appropriate immune response. In AIDS patients, combination therapy restoring immunity along with antimicrobial treatment of Cryptosporidium infection is necessary. Recent investigations focused on the potential of molecular-based immunotherapy against this parasite. Others tested the effects of probiotic bacteria, but were unable to demonstrate eradication of C. parvum. New synthetic isoflavone derivatives demonstrated excellent activity against C. parvum in vitro and in a gerbil model of infection. Newly synthesized nitroor non nitro- thiazolide compounds, derived from NTZ, have been recently shown to be at least as effective as NTZ against C. parvum in vitro development and are promising new therapeutic agents.

    Many women will likely experience a sexual problem in their lifetime. Female sexual dysfunction is a broad term used to describe 3 categories of disorders of a multifactorial nature. Effective, but limited pharmacotherapeutic options exist to address female sexual dysfunction. The FDA recently approved the first agent for treatment of hypoactive sexual desire disorder in pre-menopausal women. Off-label use of hormonal therapies, particularly oestrogen and testosterone, are the most widely employed for female sexual dysfunction, particularly in post-menopausal women. Other drugs currently under investigation include phosphodiesterase inhibitors and agents that modulate dopamine or melanocortin receptors. PMID:27041639

    Antibiotic treatment of tuberculosis has a duration of several months. There is significant variability of the host immune response and the pharmacokinetic-pharmacodynamic properties of Mycobacterium tuberculosis sub-populations at the site of disease. A limitation of sputum-based measures of treatment response may be sub-optimal detection and monitoring of Mycobacterium tuberculosis sub-populations. Potential biomarkers and surrogate endpoints should be benchmarked against hard clinical outcomes (failure/relapse/death) and may need tailoring to specific patient populations. Here, we assess the evidence supporting currently utilized and future potential host and pathogen-based models and biomarkers for monitoring treatment response in active and latent tuberculosis. Biomarkers for monitoring treatment response in extrapulmonary, pediatric and drug resistant tuberculosis are research priorities. PMID:27030924

    The neuro-transmitter serotonin seems to be important in the treatment of disturbed eating behaviour. In Anorexia Nervosa (AN) a serotonin antagonist has been proposed, whereas in Bulimia Nervosa (BN) serotonin agonists have been used with success, e.g. fenfluramine. A new generation of antidepressants has been introduced. that selectively have a serotonergic effect. The previous tricyclic and particularly the tetracyclic antidepressants had a noradrenergic effect as well. Fluoxetine belongs to the new generation. A total of 30 females with BN were treated with fluoxetine in an open study. Clinical effect was observed after 2 to 6 weeks. One patient discontinued after 3 weeks, the other were treated for 3 to 10 months. A moderate effect with 75% reduction of bingeing and purging was observed in 15 patients, 14 stopped bingeing and purging. There was no serious side effects. However, drug treatment alone had no significant effect. The fluoxetine treatment is not instead of, but in addition to the traditional behavioral treatment with strict limits regarding food and meals. PMID:2291423

    The interactions of antiepileptic drugs in multiple drug treatment have been discussed. Although some combinations may lead to predictable increase or decrease of clearance of the respective drugs, most combinations will individually lead to a reduced predictability. Monitoring plasma concentrations may lead to adaptations of the choice of the drug and of the dosage regimen. Also physiological conditions control the individual clearance of antiepileptic drugs.

    Dan Carter carefully layered the sheets of tracing paper on the light box. On each sheet were renderings of the atomic components of an essential human protein, one whose structure had long been a mystery. With each layer Carter laid down, a never-before-seen image became clearer. Carter joined NASA s Marshall Space Flight Center in 1985 and began exploring processes of protein crystal growth in space. By bouncing intense X-rays off the crystals, researchers can determine the electron densities around the thousands of atoms forming the protein molecules, unveiling their atomic structures. Cultivating crystals of sufficient quality on Earth was problematic; the microgravity conditions of space were far more accommodating. At the time, only a few hundred protein structures had been mapped, and the methods were time consuming and tedious. Carter hoped his work would help reveal the structure of human serum albumin, a major protein in the human circulatory system responsible for ferrying numerous small molecules in the blood. More was at stake than scientific curiosity. Albumin has a high affinity for most of the world s pharmaceuticals, Carter explains, and its interaction with drugs can change their safety and efficacy. When a medication enters the bloodstream a cancer chemotherapy drug, for example a majority of it can bind with albumin, leaving only a small percentage active for treatment. How a drug interacts with albumin can influence considerations like the necessary effective dosage, playing a significant role in the design and application of therapeutic measures. In spite of numerous difficulties, including having no access to microgravity following the 1986 Space Shuttle Challenger disaster, the image Carter had hoped to see was finally clarifying. In 1988, his lab had acquired specialized X-ray and detection equipment a tipping point. Carter and his colleagues began to piece together albumin s portrait, the formation of its electron densities coalescing on

    The purpose of this study is to use a modified version of Andersen’s (1968, 1995) Behavioral Model of Health Services Use to identify the correlates of the number of substance abuse treatment episodes received by rural drug users. Data were collected from face-to-face interviews with 711 drug users in rural areas of Ohio, Arkansas, and Kentucky. Descriptive analyses examine rural drug users’ substance use histories and retrospective substance abuse treatment service utilization patterns. A negative binomial regression model indicated that selected predisposing, historical health, and enabling factors were significantly associated with the utilization of substance abuse treatment among rural drug users. Despite high levels of recent and lifetime self-reported substance use among these rural drug users, treatment services were underutilized. Future studies are needed to examine the impact of the health care system and characteristics of the external environment associated with rural substance abuse treatment in order to increase utilization among drug users.

    Drug use is a complex behavior with multidimensional determinants, including social, psychological, cultural, economic, and biological factors. Blood borne viral infections including hepatitis C virus are transmitted when an uninfected intravenous drug user (IVDU) uses injection equipment, especially syringes, that have previously been used by an infected person. The transmission can also result from sharing other injection equipment such as 'cookers' and 'cottons'. Recent studies have shown that the prevalence and incidence of drug abuse have declined substantially since the introduction of needle exchange. Infection with hepatitis C may spontaneously resolve during the acute stage and never progress to chronic infection, or the infection may become chronic without medical complications, or the infection may become chronic with progressive medical complications. Regular testing for infection is an important strategy for secondary prevention of chronic hepatitis C infection. Care for hepatitis C is a vital component of a comprehensive health program for persons using illicit drugs. Such care includes screening for transmission risk behavior, prevention counseling and education, testing for HCV antibody and RNA. IDUs found to have chronic HCV infection should be assessed for the presence and degree of liver disease and evaluated for treatment for HCV Hepatitis C care also requires providing access to treatment for substance use and abuse. Therapy with opioid agonists, including methadone maintenance treatment, has been shown to diminish and often eliminate opioid use and reduce transmission of infection. Approval of buprenorphine makes office-based pharmacotherapy for opioid addiction possible. When considering treatment for hepatitis C, particular attention must be paid to mental health conditions. As a group, IDUs exhibit higher rates of comorbid psychiatric disorders than the general population. IFN-based regimens for hepatitis C are often complicated by

    Bedaquiline is a much-needed novel drug which is highly effective against drug-resistant tuberculosis. While its clinical development has been laudably fast-tracked and the drug is now available for inclusion into treatment regimens when no suitable alternatives exist, clinical experience with bedaquiline is still limited. Phase III trial data and Phase IV studies are needed particularly to study different patient populations and to optimize treatment regimens. Drug resistance to bedaquiline needs to be monitored carefully, and full access to bedaquiline treatment where it is appropriate and needed must be promoted. PMID:25797824

    Inconsistent information about drug-drug interactions can cause variations in prescribing, and possibly increase the incidence of morbidity and mortality. The aim of this study was to assess whether there is an inconsistency in drug-drug interaction listing and ranking in three authoritative, freely accessible online drug information sources: The British National Formulary; The Compendium about Drugs Licensed for Use in the United Kingdom (the Electronic Medicines Compendium) and the Compendium about Drugs Licensed for Use in the United States (the DailyMed). Information on drug-drug interactions for thirty drugs which have a high or medium potential for interactions have been selected for analysis. In total, 1971 drug-drug interactions were listed in all three drug information sources, of these 992 were ranked as the interactions with the potential of clinical significance. Comparative analysis identified that 63.98% of interactions were listed in only one drug information source, and 66.63% of interactions were ranked in only one drug information source. Only 15.12% listed and 11.19% ranked interactions were identified in all three information sources. Intraclass correlation coefficient indicated a weak correlation among the three drug information sources in listing (0.366), as well as in ranking drug interactions (0.467). This study showed inconsistency of information on drug-drug interaction for the selected drugs in three authoritative, freely accessible online drug information sources. The application of a uniform methodology in assessment of information, and then the presentation of information in a standardized format is required to prevent and adequately manage drug-drug interactions.

This improvement can be traced to a number of factors: a better understanding of cancer's cause and natural history, better technologies for early detection and diagnosis, improved control of primary tumors through surgery and radiation therapy and more effective drugs. The evolution of drug therapy for cancer has progressed rapidly from alkylating agents and antimetabolites to natural products, and most recently, molecular targeted drugs such as imatinib and gefitinib. As our understanding of the biology of cancer improves, new targets for therapy are being identified daily. [Vet. World 2011; 4(8.000: 380-382

    Fischer, Benedikt; Roberts, Julian V; Kirst, Maritt

    2002-04-01

    In Canada, illicit drug use and addiction have traditionally been considered as a criminal justice problem and have been addressed from a legal perspective. Over the past century, a medical approach to drug addiction has slowly crept into the criminal justice processing of drug offenders. This has happened through the combination of principles of punishment with principles of addiction treatment in the sentencing of drug offenders to create a distinct application of 'compulsory drug treatment' in Canada. However, this evolution has occurred sporadically over time, with punishment and coercion as predominantly the main approach to dealing with this population. This evolution has recently culminated in Canada with the development of two criminal justice approaches to dealing with the substance use problems of drug offenders that incorporate concepts of punishment and treatment more equally than ever before - conditional sentencing and drug courts. This paper outlines the historical evolution of concepts of 'compulsory treatment', discusses such examples of contemporary 'compulsory treatment' as conditional sentencing and drug courts, and analyses the implications, concerns and challenges associated with these tools currently used in the sentencing of drug offenders in the Canadian context.

  15. Health care policy issues in the drug abuser treatment field.

    Science.gov (United States)

    McAuliffe, W E

    1990-01-01

    As we enter the 1990s drug abuse has once again become a major health concern, and for the first time the drug treatment field has had to address many of the policy, regulation, and planning issues resulting from cost inflation that have become commonplace in other parts of the health care field. To avoid serious errors and confusion, drug abuse health policies must recognize the very different needs of the public and private sectors. The public sector, where poor addicts receive drug treatment provided or purchased by the government, has long suffered from chronically inadequate funding. Although responses to several epidemics (heroin, crack, and AIDS) have produced periods of increased allocations for drug abuse treatment, more often than not long waiting lists at programs have rationed treatment to lower-income addicts seeking care. Low salary levels have limited the quality of public treatment services, and the absence of resources has hindered the development of programs that respond to new technical developments and drug abuse problems, such as the crack epidemic. Despite severe resource shortages, the public drug treatment system has sometimes used resources inefficiently, with little attention to appropriateness of admissions, lengths of stay, ambulatory treatment modalities, or varying levels of care. Public sector goals for the 1990s should include filling current shortages in drug treatment services, developing adequate long-term funding for treating addicts who lack third-party coverage, modernizing the treatment system, developing new patterns of practice that use existing resources more efficiently, and developing a plan for treating intravenous drug users infected with the AIDS virus. In the private sector, the advent of working- and middle-class demand for drug treatment in the 1970s and 1980s has produced a new drug treatment system that suffers from many of the policy problems common to the rest of health care.

    Full Text Available Abstract Drug use is prevalent throughout prison populations, and, despite advances in drug treatment programmes for inmates, access to and the quality of these programmes remain substantially poorer than those available for non-incarcerated drug users. Because prisoners may be at greater risk for some of the harms associated with drug use, they deserve therapeutic modalities and attitudes that are at least equal to those available for drug users outside prison. This article discusses drug use by inmates and its associated harms. In addition, this article provides a survey of studies conducted in prisons of opioid substitution therapy (OST, a clinically effective and cost-effective drug treatment strategy. The findings from this overview indicate why treatment efforts for drug users in prison are often poorer than those available for drug users in the non-prison community and demonstrate how the implementation of OST programmes benefits not only prisoners but also prison staff and the community at large. Finally, the article outlines strategies that have been found effective for implementing OST in prisons and offers suggestions for applying these strategies more broadly.

    Full Text Available This secondary analysis study investigated HIV sexual and drug-use risk in drug-dependent pregnant patients over the first month postrandomization to reinforcement-based treatment (RBT (=47 or usual care (UC (=42. Analysis of primary outcomes had indicated that RBT participants spent significantly longer time in treatment and recovery housing than UC participants. The present study examined the ability of 9 risk markers—age, race, estimated gestational age at treatment entry, lifetime substance abuse treatment episodes, history of prostitution charges, history of serious depression, current heroin injection status, current housing status, and current partner substance use—to predict changes in HIV risks. Sexual risk declined for participant subgroups with prostitution-charge histories and unstable housing. Drug-use risk declined for heroin injectors and nondepressed participants. A relationship was found between number of lifetime drug treatment episodes and sexual and drug-use risk. The role of risk markers in the response of drug-dependent pregnant women to drug treatment require attention.

  10. Therapeutic drug monitoring: how to improve drug dosage and patient safety in tuberculosis treatment

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available In this article we describe the key role of tuberculosis (TB treatment, the challenges (mainly the emergence of drug resistance, and the opportunities represented by the correct approach to drug dosage, based on the existing control and elimination strategies. In this context, the role and contribution of therapeutic drug monitoring (TDM is discussed in detail. Treatment success in multidrug-resistant (MDR TB cases is low (62%, with 7% failing or relapsing and 9% dying and in extensively drug-resistant (XDR TB cases is even lower (40%, with 22% failing or relapsing and 15% dying. The treatment of drug-resistant TB is also more expensive (exceeding €50 000 for MDR-TB and €160 000 for XDR-TB and more toxic if compared to that prescribed for drug-susceptible TB. Appropriate dosing of first- and second-line anti-TB drugs can improve the patient's prognosis and lower treatment costs. TDM is based on the measurement of drug concentrations in blood samples collected at appropriate times and subsequent dose adjustment according to the target concentration. The ‘dried blood spot’ technique offers additional advantages, providing the rationale for discussions regarding a possible future network of selected, quality-controlled reference laboratories for the processing of dried blood spots of difficult-to-treat patients from reference TB clinics around the world.

    1990-09-01

    Issues concerning sympathomimetic drug treatment of children with attentional problems and hyperactivity are considered in light of cumulative and current research. These issues concern the atypical or "paradoxical" drug response of such children, predictability of drug response from neurological or biochemical assessments, and, especially, long-term outcome or effectiveness of sympathomimetic medication. Short-term drug effects on behavior and performance are well documented. However, follow-up studies that exist presently suggest little long-term impact of sympathomimetic drugs on school achievement, peer relationships, or behavior problems in adolescence. Questions remain concerning development of tolerance in children, ways to define subgroups of disordered children who may respond uniquely to stimulants, the efficacy of medication in combination with other treatments, and possible long-term negative consequences of medication.

    Full Text Available Abstract Background The purpose of this study was to assess the impact of drug abuse treatment in Peru that used the therapeutic community (TC model. Program directors and several staff members from all study treatment facilities received two to eight weeks of in-country training on how to implement the TC treatment model prior to the follow-up study. Methods This outcome study involved 33 TC treatment facilities and 509 former clients in Lima and other cities in five providences across Peru. A retrospective pre-test (RPT follow-up design was employed in which 30-day use of illegal drugs and alcohol to intoxication was measured at baseline retrospectively, at the same time of the six-month follow-up. In-person interview data were collected from directors of 73 percent of the eligible TC organizations in January and February 2003 and from former 58 percent of the eligible TC former clients between October 2003 and October 2004. Drug testing was conducted on a small sample of former clients to increase the accuracy of the self-reported drug use data. Results Medium to large positive treatment effects were found when comparing 30-day illegal drug and alcohol use to intoxication before and six months after receiving treatment. As a supplemental analysis, we assumed the 42 percent of the former clients who were not interviewed at the six month assessment had returned to drugs. These results showed medium treatment effects as well. Hierarchical Generalized Linear Modeling (HGLM results showed higher implementation fidelity, less stigma after leaving treatment, and older clients, singly or in combination are key predictors of treatment success. Conclusion This study found that former clients of drug and alcohol treatment in facilities using the TC model reported substantial positive change in use of illegal drugs and alcohol to intoxication at a six-month follow-up. The unique contribution of this study is that the results also suggest attention should

    The advent of combination antiretroviral therapy (ART) has significantly decreased AIDS-related morbidity and mortality. Nevertheless, the benefits of ART are only realized through adherence to lifelong treatment. Though contemporary antiretroviral (ARV) drugs have fewer adverse effects in comparison to older ARV drugs, many agents are associated with negative or unknown long-term effects. There is increasing evidence that two-drug (dual-therapy) regimens may be an effective alternative to the currently recommended three-drug (triple-therapy) regimens. In this review, we provide a comprehensive and critical review of recently completed and ongoing trials of dual-therapy regimens in treatment-naïve and treatment-experienced HIV-1-infected patients. We also review current HIV/AIDS society recommendations regarding dual therapy as well as future therapeutic possibilities. PMID:26886135

  17. Can antipsychotic treatment contribute to drug addiction in schizophrenia?

    Science.gov (United States)

    Samaha, Anne-Noël

    2014-07-01

    Individuals with schizophrenia are at very high risk for drug abuse and addiction. Patients with a coexisting drug problem fare worse than patients who do not use drugs, and are also more difficult to treat. Current hypotheses cannot adequately account for why patients with schizophrenia so often have a co-morbid drug problem. I present here a complementary hypothesis based on evidence showing that chronic exposure to antipsychotic medications can induce supersensitivity within the brain's dopamine systems, and that this in turn can enhance the rewarding and incentive motivational effects of drugs and reward cues. At the neurobiological level, these effects of antipsychotics are potentially linked to antipsychotic-induced increases in the striatal levels of dopamine D2 receptors and D2 receptors in a high-affinity state for dopamine, particularly at postsynaptic sites. Antipsychotic-induced dopamine supersensitivity and enhanced reward function are not inevitable consequences of prolonged antipsychotic treatment. At least two parameters appear to promote these effects; the use of antipsychotics of the typical class, and continuous rather than intermittent antipsychotic exposure, such that silencing of dopaminergic neurotransmission via D2/3 receptors is unremitting. Thus, by inducing forms of neural plasticity that facilitate the ability of drugs and reward cues to gain control over behaviour, some currently used treatment strategies with typical antipsychotics might contribute to compulsive drug seeking and drug taking behaviours in vulnerable schizophrenia patients.

    Zhang, Sheldon X; Roberts, Robert E L; Lansing, Amy E

    2013-07-01

    This study evaluated a community-based correctional program in California, in which parolees tested positive on illicit drugs were given the option of going into a treatment program or having their parole revoked and returned to prison in California. Two comparison groups were constructed to assess the treatment effect-a propensity-based comparison group extracted from the general parolee population and program dropouts. Although implicitly coercive, some parolees who finished the program were less likely to be reincarcerated 12 months following release than both comparison groups. However, the observed treatment advantage quickly eroded in the second observation year. Savings realized from the incarcerations avoided were more than enough to pay for the program. Findings from this study suggest that boosting participation in reentry services through coercive measures may yield currently unrealized individual and societal benefits. However, systemic efforts are needed to extend the short-term treatment effects. Design and data limitations in the study weaken the persuasiveness of these findings. Methodological implications and policy issues about coerced treatment are discussed. PMID:22436733

    2015-01-01

    Elevated eye pressure is the main risk factor for glaucoma; intraocular pressure rises when the ratio between aqueous humor formation (inflow) and its outflow is unbalanced. Currently, the main goal of medical treatment is the reduction of intraocular pressure. Five main classes of topical drugs are available; they include betablockers, carbonic anhydrase inhibitors, prostaglandin derivatives, sympathomimetics and miotics. Beta-blockers and carbonic anhydrase inhibitors slow the formation of aqueous humor and may be considered as "inflow" drugs; the other three classes reduce the resistance to the drainage of aqueous humor and may be considered as "outflow" drugs. Despite the variety of drugs accessible in the market, there is a real need for ophthalmologists to have more potent medications for this disease. This review focuses on medical treatment of glaucoma with particular attention to novel molecules in pre-clinical or clinical development. PMID:26350532

    Knowledge of patterns of treatment discontinuation in attention-deficit/hyperactivity disorder (ADHD) drug treatment is of importance, for both the clinical practice and the study of long-term treatment outcomes. The purpose of this study was to describe early discontinuation of ADHD drug treatment. Using the Danish National Prescription Registry, all first-time users of the ADHD drugs methylphenidate and atomoxetine were identified between 2000 and 2012. Early discontinuation was defined as failing to fill a second prescription for any ADHD drug within 6 months. Analyses were conducted stratified by calendar year, drug formulation, patient sex, age and region of residence. 59,116 first-time users of methylphenidate and atomoxetine with at least 6 months of eligible follow-up were identified. Overall, 12.6% (n = 7441) failed to fill a second prescription within 6 months. This proportion changed over time, dropping from 20.8% in 2000 to 12.5% in 2012. The proportion of early discontinuation was considerably lower among children than among adults. Proportions were comparable when stratifying by index drug. Proportions of early discontinuation were similar between regions of Denmark, except in the capital region, where it remained at around 20% among 18- to 49-year-olds throughout the study period (22.6% in 2012). In conclusion, we found that the proportion of early discontinuation among ADHD drug users in Denmark dropped markedly during the past decade for both sexes, all age groups and all regions, except for adults in the capital region. Overall, early discontinuation was somewhat lower than expected, considering rates of side effects or non-response to ADHD drug treatment. PMID:25220739

    Full Text Available In addition to epilepsy, antiepileptic drugs are used in neurologic conditions such as chronic pain and in the treatment of bipolar disorder in psychiatry. There are studies reporting its use in the treatment of anxiety disorders. The efficacy of antiepileptic drugs as carbamazepine, valproic asid, lamotrigine, topiramate, gabapentin, pregabalin in anxiety disorders has been shown in some clinical studies. The strongest evidence has been presented for pregabalin in generalized anxiety disorder, pregabalin and gabapentin in social anxiety disorder and lamotrigine in posttraumatic stres disorder. While certain studies report the effectiveness of antiepileptic drugs in the treatment of anxiety disordes, others report them as ineffective. Double blind placebo controlled drug trials are essential for clearly presenting anxiolytic activity of antiepileptic drugs which would lead the way to further wide scale use in clinical practice. This article focuses on recent literature to show the potential use of antiepileptic drugs in patients suffering from generalized anxiety disorder, social anxiety disorder, posttraumatic stres disorder, panic disorder along with a brief review of neuroanatomic structures and neurotransmitters associated with epilepsy and anxiety disorders.

    2010-07-01

    Full Text Available Obesity is a chronic disease associated with excess morbidity and mortality. Clinical treatment, however, currently offers disappointing results, with very high rates of weight loss failure or weight regain cycles, and only two drugs (orlistat and sibutramine approved for long-term use. Drugs combinations can be an option for its treatment but, although widely used in clinical practice, very few data are available in literature for its validation. Our review focuses on the rationale for their use, with advantages and disadvantages; on combinations often used, with or without studies; and on new perspectives of combinations being studied mainly by the pharmaceutical industry.

  20. Significance and challenges of stereoselectivity assessing methods in drug metabolism

    Directory of Open Access Journals (Sweden)

    2016-02-01

    Full Text Available Stereoselectivity in drug metabolism can not only influence the pharmacological activities, tolerability, safety, and bioavailability of drugs directly, but also cause different kinds of drug–drug interactions. Thus, assessing stereoselectivity in drug metabolism is of great significance for pharmaceutical research and development (R&D and rational use in clinic. Although there are various methods available for assessing stereoselectivity in drug metabolism, many of them have shortcomings. The indirect method of chromatographic methods can only be applicable to specific samples with functional groups to be derivatized or form complex with a chiral selector, while the direct method achieved by chiral stationary phases (CSPs is expensive. As a detector of chromatographic methods, mass spectrometry (MS is highly sensitive and specific, whereas the matrix interference is still a challenge to overcome. In addition, the use of nuclear magnetic resonance (NMR and immunoassay in chiral analysis are worth noting. This review presents several typical examples of drug stereoselective metabolism and provides a literature-based evaluation on current chiral analytical techniques to show the significance and challenges of stereoselectivity assessing methods in drug metabolism.

    2014-12-01

    Full Text Available Helminth infections are responsible for a considerable public health burden, yet the current drug armamentarium is small. Given the high cost of drug discovery and development, the high failure rates and the long duration to develop novel treatments, drug repurposing circumvents these obstacles by finding new uses for compounds other than those they were initially intended to treat. In the present review, we summarize in vivo and clinical trial findings testing clinical candidates and marketed drugs against schistosomes, food-borne trematodes, soil-transmitted helminths, Strongyloides stercoralis, the major human filariases lymphatic filariasis and onchocerciasis, taeniasis, neurocysticercosis and echinococcosis. While expanding the applications of broad-spectrum or veterinary anthelmintics continues to fuel alternative treatment options, antimalarials, antibiotics, antiprotozoals and anticancer agents appear to be producing fruitful results as well. The trematodes and nematodes continue to be most investigated, while cestodal drug discovery will need to be accelerated. The most clinically advanced drug candidates include the artemisinins and mefloquine against schistosomiasis, tribendimidine against liver flukes, oxantel pamoate against trichuriasis, and doxycycline against filariasis. Preclinical studies indicate a handful of promising future candidates, and are beginning to elucidate the broad-spectrum activity of some currently used anthelmintics. Challenges and opportunities are further discussed.

    2015-09-01

    Graves' disease is the most common cause of hyperthyroidism in iodine-replete areas and is ultimately due to antibodies interacting with the TSH receptor on thyroid follicular cells [TSH-receptor antibody (TRAb)]. Antithyroid drugs (ATDs) belonging to the family of thionamides are the first-line treatment in Europe. ATD treatment is commonly continued for 18-24 months. Its major limitation is the high rate of relapses after drug withdrawal. Factors particularly bound to subsequent relapses are the large thyroid volume, smoking habit, persistence of TRAb in the circulation at the end of treatment, and the post-partum period. Under these conditions, consideration should be given to a definitive therapy for hyperthyroidism (radioiodine treatment, thyroidectomy), particularly if the patient is at risk of cardiovascular complications that might be exacerbated by persistence or recurrence of hyperthyroidism.

    2008-08-01

    The main objective of the present work is to understand the processes used in emerging Catholic and Protestant religious interventions for recovery from drug dependence, from the vantage point of individuals subjected to them. A qualitative method and an intentional sample selected by criteria were adopted for this investigation, which was conducted in São Paulo, Brazil. An in-depth semi-structured interview was conducted with 57 predominantly male former drug users who fit the criteria: they had been submitted to non-medical religious treatments to treat dependence and were abstinent for at least 6 months. Crisis was found to be the main reason leading interviewees to seek treatment; this includes, losing family, losing employment, and experiencing severe humiliation. Evangelicals most used religious resources exclusively as treatment, showing strong aversion to the role of doctors and to any type of pharmacological treatment. A common feature of Catholic and Protestant groups is the importance ascribed to praying and talking to God, described by subjects as strongly anxiolytic, and a means to control drug craving. Confession and forgiveness, through faith conversion or penitences, respectively, appeal strongly to the restructuring of life and increase of self-esteem. Religious interventions were considered effective by the individuals who underwent them and were seen as attractive for the humane, respectful treatment they delivered. The key aspects of this type of treatment are social support provided by the receiving group, equal treatment, and instant, judgment-free acceptance. The success of these actions, then, is not only due to some "supernatural" aspect, as might be assumed, but also more to the unconditional dedication of human beings to their peers. Given the difficulty in treating drug dependence, religious interventions could be used as a complementary treatment for conventional therapies. PMID:18501491

  5. Treatment Approaches for Interoceptive Dysfunctions in Drug Addiction

    Directory of Open Access Journals (Sweden)

    Martin P Paulus

    2013-10-01

    Full Text Available There is emerging evidence that individuals with drug addiction have dysfunctions in brain systems that are important for interoceptive processing, which include, among others, the insular and the anterior cingulate cortices. These individuals may not be expending sufficient neural resources to process perturbations of the interoceptive state but may exert over-activation of these systems when processing drug-related stimuli. As a consequence, insufficient detection and processing of interoceptive state changes may result in inadequate anticipation and preparation to adapt to environmental challenges, e.g. adapt to abstinence in the presence of withdrawal symptoms. Here, we integrate interoceptive dysfunction in drug-addicted individuals, with the neural basis for meditation and exercise to develop a heuristic to target the interoceptive system as potential treatments for drug addiction. First, it is suggested that mindfulness-based approaches can modulate both interoceptive function and insular activation patterns. Second, there is an emerging literature that the regulation of physical exercise in the brain involves the insula and anterior cingulate cortex and that intense physical exercise is associated with a state-dependent activation difference in the insula that may provide a window to attenuate the increased interoceptive response drug related stimuli. It is concluded that the conceptual framework of interoceptive dysfunctions in drug addiction and the experimental findings in meditation and exercise provide a useful approach to develop new interventions for drug addiction.

  13. Is immunotherapy an opportunity for effective treatment of drug addiction?

    Zalewska-Kaszubska, Jadwiga

    2015-11-27

    Immunotherapy has a great potential of becoming a new therapeutic strategy in the treatment of addiction to psychoactive drugs. It may be used to treat addiction but also to prevent neurotoxic complications of drug overdose. In preclinical studies two immunological methods have been tested; active immunization, which relies on the administration of vaccines and passive immunization, which relies on the administration of monoclonal antibodies. Until now researchers have succeeded in developing vaccines and/or antibodies against addiction to heroin, cocaine, methamphetamine, nicotine and phencyclidine. Their effectiveness has been confirmed in preclinical studies. At present, clinical studies are being conducted for vaccines against nicotine and cocaine and also anti-methamphetamine monoclonal antibody. These preclinical and clinical studies suggest that immunotherapy may be useful in the treatment of addiction and drug overdose. However, there are a few problems to be solved. One of them is controlling the level of antibodies due to variability between subjects. But even obtaining a suitable antibody titer does not guarantee the effectiveness of the vaccine. Additionally, there is a risk of intentional or unintentional overdose. As vaccines prevent passing of drugs through the blood/brain barrier and thereby prevent their positive reinforcement, some addicted patients may erroneously seek higher doses of psychoactive substances to get "high". Consequently, vaccination should be targeted at persons who have a strong motivation to free themselves from drug dependency. It seems that immunotherapy may be an opportunity for effective treatment of drug addiction if directed to adequate candidates for treatment. For other addicts, immunotherapy may be a very important element supporting psycho- and pharmacotherapy. PMID:26432911

    Tuberculosis is the leading infectious cause of death worldwide, with 9·6 million cases and 1·5 million deaths reported in 2014. WHO estimates 480 000 cases of these were multidrug resistant (MDR). Less than half of patients who entered into treatment for MDR tuberculosis successfully completed that treatment, mainly due to high mortality and loss to follow-up. These in turn illustrate weaknesses in current treatment regimens and national tuberculosis programmes, coupled with operational treatment challenges. In this Review we provide an update on recent developments in the tuberculosis drug-development pipeline (including new and repurposed antimicrobials and host-directed drugs) as they are applied to new regimens to shorten and improve outcomes of tuberculosis treatment. Several new or repurposed antimicrobial drugs are in advanced trial stages for MDR tuberculosis, and two new antimicrobial drug candidates are in early-stage trials. Several trials to reduce the duration of therapy in MDR and drug-susceptible tuberculosis are ongoing. A wide range of candidate host-directed therapies are being developed to accelerate eradication of infection, prevent new drug resistance, and prevent permanent lung injury. As these drugs have been approved for other clinical indications, they are now ready for repurposing for tuberculosis in phase 2 clinical trials. We assess risks associated with evaluation of new treatment regimens, and highlight opportunities to advance tuberculosis research generally through regulatory innovation in MDR tuberculosis. Progress in tuberculosis-specific biomarkers (including culture conversion, PET and CT imaging, and gene expression profiles) can support this innovation. Several global initiatives now provide unique opportunities to tackle the tuberculosis epidemic through collaborative partnerships between high-income countries and middle-income and low-income countries for clinical trials training and research, allowing funders to

  18. Drug combination against single drug treatment in radiation protection of the bone marrow CFU

    International Nuclear Information System (INIS)

    The effectiveness of two doses of WR-2721 (300 mg/kg and 150 mg/kg body weight) alone or in combination with an optimal dose (20 mg/kg body weight) of MPG, on the mouse bone marrow was studied by the exogenous spleen colony assay (CFU-s) after a single whole body exposure to 4.5 Gy of gamma radiation. Both the drugs individually increased the number of spleen colonies significantly above that of the irradiated control indicating higher stem cell survival. WR-2721 treatment gave better protection than MPG. MPG was more effective when administered within 5 min before or after irradiation than when given 30 to 25 min before irradiation. The combination of WR-2721, at either dose, with 20 mg/kg MPG gave an increase in the stem cell survival as compared to the single drug treatments and this effect was synergistic at 300 mg/kg WR-2721. MPG treatment within 5 min after irradiation produced a slightly higher CFU-s count than when the drug was injected before irradiation, though the difference was not statistically significant. It is concluded that in addition to the doses of the drug, the time of administration also could influence the effect of drug combinations. (orig.)

    Full Text Available Dovitinib (TKI-258 is under development for the treatment of diverse cancer entities. No published information on its pharmacokinetic drug interaction potential is available. Thus, we assessed its interaction with important drug metabolising enzymes and drug transporters and its efficacy in multidrug resistant cells in vitro. P-glycoprotein (P-gp, MDR1, ABCB1 inhibition was evaluated by calcein assay, inhibition of breast cancer resistance protein (BCRP, ABCG2 by pheophorbide A efflux, and inhibition of organic anion transporting polypeptides (OATPs by 8-fluorescein-cAMP uptake. Inhibition of cytochrome P450 3A4, 2C19, and 2D6 was assessed by using commercial kits. Induction of transporters and enzymes was quantified by real-time RT-PCR. Possible aryl hydrocarbon receptor (AhR activating properties were assessed by a reporter gene assay. Substrate characteristics were evaluated by growth inhibition assays in cells over-expressing P-gp or BCRP. Dovitinib weakly inhibited CYP2C19, CYP3A4, P-gp and OATPs. The strongest inhibition was observed for BCRP (IC50 = 10.3 ± 4.5 μM. Among the genes investigated, dovitinib only induced mRNA expression of CYP1A1, CYP1A2, ABCC3 (coding for multidrug resistance-associated protein 3, and ABCG2 and suppressed mRNA expression of some transporters and drug metabolising enzymes. AhR reporter gene assay demonstrated that dovitinib is an activator of this nuclear receptor. Dovitinib retained its efficacy in cell lines over-expressing P-gp or BCRP. Our analysis indicates that dovitinib will most likely retain its efficacy in tumours over-expressing P-gp or BCRP and gives first evidence that dovitinib might act as a perpetrator drug in pharmacokinetic drug–drug interactions.

    Alisporivir is a novel cyclophilin-binding molecule with potent anti-hepatitis C virus (HCV) activity. In vitro data from human liver microsomes suggest that alisporivir is a substrate and a time-dependent inhibitor (TDI) of CYP3A4. The aim of the current work was to develop a novel physiologically based pharmacokinetic (PBPK) model to quantitatively assess the magnitude of CYP3A4 mediated drug-drug interactions with alisporivir as the substrate or victim drug. Towards that, a Simcyp PBPK model was developed by integrating in vitro data with in vivo clinical findings to characterize the clinical pharmacokinetics of alisporivir and further assess the magnitude of drug-drug interactions. Incorporated with absorption, distribution, elimination, and TDI data, the model accurately predicted AUC, Cmax, and tmax values after single or multiple doses of alisporivir with a prediction deviation within ± 32%. The model predicted an alisporivir AUC increase by 9.4-fold and a decrease by 86% when alisporivir was co-administrated with ketoconazole (CYP3A4 inhibitor) or rifampin (CYP3A4 inducer), respectively. Predictions were within ± 20% of the observed changes. In conclusion, the PBPK model successfully predicted the alisporivir PK and the magnitude of drug-drug interactions. PMID:25008118

    Anorexia and bulimia are eating disorders affecting a significant number of adolescent and young adult women. The core symptoms of both disorders are similar and include a fear of obesity, body image disturbance, erratic eating patterns, and purging. These symptoms produce significant physical and psychologic complications. Both anorexia and bulimia appear to have a common origin in a fear of obesity and dieting. Anorectics, being "successful" dieters, lose a significant amount of weight; whereas bulimics alternate between binges and purges. Treatment for the eating disorders is gradually evolving as clinical research experience accumulates. For anorexia, hospitalization is indicated when weight falls below 15% of ideal, and most investigators agree that therapy for the core symptoms cannot be undertaken until weight is restored. During the impatient stay, a behavior modification program can effectively organize medical, nutritional, and psychologic support, and offers the quickest and most direct route to weight restoration. The nasogastric tube and total parenteral nutrition are used primarily for those who are severely emaciated or who actively resist standard modes of therapy. Inpatient treatment is most effectively and efficiently rendered in a specialized eating disorder unit. Once weight restoration is progressing, behavior therapy for core symptoms is commenced and continued on an outpatient basis. A variety of behavioral techniques are employed, and they are designed primarily to influence anorectic assumptions and beliefs. Although there may be a brief inpatient stay for initiation of treatment, the bulk of therapy for bulimia occurs on an outpatient basis. The available literature indicates that behavioral techniques and antidepressant medication are effective for the symptoms of bulimia. Early identification of core symptoms of both disorders can lead to an initiation of treatment before the core symptoms become ingrained. A potentially more effective

    Full Text Available The use of cardiovascular drugs is related to the development of adverse drug reactions (ADRs in about 24% of the patients in the Cardiovascular Care Unit. Here, we evaluated the ADRs in patients treated with antihypertensive drugs. The study was conducted in two phases: In the first phase, we performed a retrospective study on clinical records of Clinical Divisions (i.e., Internal Medicine Operative Unit and Geriatric Operative Unit from January 1, 2012 to December 31, 2012. Moreover from January 1, 2013 to March 30, 2013 we performed a prospective study on the outpatients attending the Emergency Department (ED of the Pugliese-Ciaccio Hospital of Catanzaro, by conducting patient interviews after their informed consent was obtained. The association between a drug and ADR was evaluated using the Naranjo scale. We recorded 72 ADRs in the Clinical Divisions and six in the ED, and these were more frequent in women. Using the Naranjo score, we showed a probable association in 92% of these reactions and a possible association in 8%. The most vulnerable age group involved in ADRs was that of the elderly patients. In conclusion, our results indicate that antihypertensive drugs may be able to induce the development of ADRs, particularly in elderly women receiving multiple drug treatment. Therefore, it is important to motivate the healthcare providers to understand their role and responsibility in the detection, management, documentation, and reporting of ADRs, as also all the essential activities for optimizing patient safety.

    Full Text Available Schistosomiasis is a parasitic disease that, according to the World Health Organization, constitutes a major public health problem associated with severe morbidity, mostly children in preschool age. The administration of drugs in children always constitutes a difficult task, especially when formulations are not developed specifically for pediatric use, when high doses of drug are required and the drug has a bitter taste, as in the case of praziquantel. Polymer nanoparticles are promising systems for development of encapsulated drugs with low water solubility and bitter taste, due to the good physical and chemical stability, adequate biocompatibility and simple manufacturing processes. Moreover, they can enhance the bioavailabili-ty and reduce variability of treatment among patients. Poly (methyl methacrylate doped with praziquantel was produced through a miniemulsion polymerization pro-cess to compose a pediatric pharmaceutical suspension. Nanoparticles were cha-racterized in terms of physico-chemical properties, toxicological properties and biological activity in mice, being concluded that obtained results were satisfactory. The results were encapsulation rate around 90%, absence of chemical interaction drug - polymer and the presence of biological activity. A collaborative approach was used for this development, involving national partnerships and independent funding mechanisms, a powerful pathway for development of drugs for neglected diseases.

    Background. Increasing access to drugs for the treatment of multidrug-resistant (MDR) tuberculosis is crucial but could lead to increasing resistance to these same drugs. In 2000, the international Green Light Committee (GLC) initiative began to increase access while attempting to prevent acquired resistance. Methods. To assess the GLC's impact, we followed adults with pulmonary MDR tuberculosis from the start to the end of treatment with monthly sputum cultures, drug susceptibility testing, and genotyping. We compared the frequency and predictors of acquired resistance to second-line drugs (SLDs) in 9 countries that volunteered to participate, 5 countries that met GLC criteria, and 4 countries that did not apply to the GLC. Results. In total, 832 subjects were enrolled. Of those without baseline resistance to specific SLDs, 68 (8.9%) acquired extensively drug-resistant (XDR) tuberculosis, 79 (11.2%) acquired fluoroquinolone (FQ) resistance, and 56 (7.8%) acquired resistance to second-line injectable drugs (SLIs). The relative risk (95% confidence interval [CI]) of acquired resistance was lower at GLC-approved sites: 0.27 (.16–.47) for XDR tuberculosis, 0.28 (.17–.45) for FQ, and 0.15 (.06–.39) to 0.60 (.34–1.05) for 3 different SLIs. The risk increased as the number of potentially effective drugs decreased. Controlling for baseline drug resistance and differences between sites, the odds ratios (95% CIs) were 0.21 (.07–.62) for acquired XDR tuberculosis and 0.23 (.09–.59) for acquired FQ resistance. Conclusions. Treatment of MDR tuberculosis involves substantial risk of acquired resistance to SLDs, increasing as baseline drug resistance increases. The risk was significantly lower in programs documented by the GLC to meet specific standards. PMID:25057101

    Retrospective study of jaw osteonecrosis treatment in patients using the "Krokodil" drug from 2009 to 2013. On the territory of the former USSR countries there is widespread use of a self-produced drug called "Krokodil". Codeine containing analgesics ("Sedalgin", "Pentalgin" etc), red phosphorus (from match boxes) and other easily acquired chemical components are used for synthesis of this drug, which used intravenously. Jaw osteonecrosis develops as a complication in patients who use "Krokodil". The main feature of this disease is jawbone exposure in the oral cavity. Surgery is the main method for the treatment of jaw osteonecrosis in patients using "Krokodil". 40 "Krokodil" drug addict patients with jaw osteonecrosis were treated. Involvement of maxilla was found in 11 patients (27.5%), mandible in 21 (52.5%), both jaws in 8 (20%) patients. 35 Lesions were found in 29 mandibles and 21 lesions in 19 maxillas. Main factors of treatment success are: cessation of "Krokodil" use in the pre- (minimum 1 month) and postoperative period and osteonecrosis area resection of a minimum of 0.5 cm beyond the visible borders of osteonecrosis towards the healthy tissues. Surgery was not delayed until sequestrum formation. In the mandible marginal or segmental resection (with or without TMJ exarticulation) was performed. After surgery recurrence of disease was seen in 8 (23%) cases in the mandible, with no cases of recurrence in the maxilla. According to our experience in this case series, surgery is the main method for the treatment of jaw osteonecrosis in patients using "Krokodil". Cessation of drug use and jaw resection minimize the rate of recurrences in such patients. PMID:24969764

    Drug-drug interactions (DDIs) may result in the alteration of therapeutic response. Sometimes they may increase the untoward effects of many drugs. Hospitalized cardiac patients need more attention regarding drug-drug interactions due to complexity of their disease and therapeutic regimen. This research was performed to find out types, prevalence and association between various predictors of potential drug-drug interactions (pDDIs) in the Department of Cardiology and to report common interactions. This study was performed in the hospitalized cardiac patients at Ayub Teaching Hospital, Abbottabad, Pakistan. Patient charts of 2342 patients were assessed for pDDIs using Micromedex® Drug Information. Logistic regression was applied to find predictors of pDDIs. The main outcome measure in the study was the association of the potential drug-drug interactions with various factors such as age, gender, polypharmacy, and hospital stay of the patients. We identified 53 interacting-combinations that were present in total 5109 pDDIs with median number of 02 pDDIs per patient. Overall, 91.6% patients had at least one pDDI; 86.3% were having at least one major pDDI, and 84.5% patients had at least one moderate pDDI. Among 5109 identified pDDIs, most were of moderate (55%) or major severity (45%); established (24.2%), theoretical (18.8%) or probable (57%) type of scientific evidence. Top 10 common pDDIs included 3 major and 7 moderate interactions. Results obtained by multivariate logistic regression revealed a significant association of the occurrence of pDDIs in patient with age of 60 years or more (p Older patients, patients with longer hospital stay and with elevated number of prescribed drugs were at higher risk of pDDIs.

    Full Text Available Abstract Background Oral health behavior (OHB, one major factor contributing to proper oral health status, has been addressed insufficiently in addiction literature. The aim of our study was to investigate OHB and its determinants among drug addicts in withdrawal treatment. Methods Through a stratified cluster sampling method, we collected the data from 685 patients in withdrawal treatment in Tehran using self-administered questionnaires on OHB components and conducting interviews about patients’ characteristics and addiction history. The T-test, ANOVA, and a linear regression model served for statistical analysis. Results Of the patients, 48% reported brushing their teeth less than once a day, more than 90% used fluoride toothpaste almost or always, and 81% flossed their teeth rarely or never. Eating sugary products twice a day or more was reported by 57% of the patients and 85% of them were current smokers. Poor OHB was associated with male gender, lower education, being addicted mainly to crystalline heroin, starting drug abuse at a younger age, and having a longer history of addiction (p  Conclusion Poor OHB was found among the participants in drug withdrawal treatment. Preventive strategies on oral health should be planned and be integrated into other health promotion programs for addicts along with their withdrawal treatment taking into account special groups at higher risk.

  8. Enhanced transmission of drug-resistant parasites to mosquitoes following drug treatment in rodent malaria.

    Directory of Open Access Journals (Sweden)

    Andrew S Bell

    Full Text Available The evolution of drug resistant Plasmodium parasites is a major challenge to effective malaria control. In theory, competitive interactions between sensitive parasites and resistant parasites within infections are a major determinant of the rate at which parasite evolution undermines drug efficacy. Competitive suppression of resistant parasites in untreated hosts slows the spread of resistance; competitive release following treatment enhances it. Here we report that for the murine model Plasmodium chabaudi, co-infection with drug-sensitive parasites can prevent the transmission of initially rare resistant parasites to mosquitoes. Removal of drug-sensitive parasites following chemotherapy enabled resistant parasites to transmit to mosquitoes as successfully as sensitive parasites in the absence of treatment. We also show that the genetic composition of gametocyte populations in host venous blood accurately reflects the genetic composition of gametocytes taken up by mosquitoes. Our data demonstrate that, at least for this mouse model, aggressive chemotherapy leads to very effective transmission of highly resistant parasites that are present in an infection, the very parasites which undermine the long term efficacy of front-line drugs.

  9. Liposome-based drug delivery in breast cancer treatment

    International Nuclear Information System (INIS)

    Drug delivery systems can in principle provide enhanced efficacy and/or reduced toxicity for anticancer agents. Long circulating macromolecular carriers such as liposomes can exploit the 'enhanced permeability and retention' effect for preferential extravasation from tumor vessels. Liposomal anthracyclines have achieved highly efficient drug encapsulation, resulting in significant anticancer activity with reduced cardiotoxicity, and include versions with greatly prolonged circulation such as liposomal daunorubicin and pegylated liposomal doxorubicin. Pegylated liposomal doxorubucin has shown substantial efficacy in breast cancer treatment both as monotherapy and in combination with other chemotherapeutics. Additional liposome constructs are being developed for the delivery of other drugs. The next generation of delivery systems will include true molecular targeting; immunoliposomes and other ligand-directed constructs represent an integration of biological components capable of tumor recognition with delivery technologies

Furthermore, there will be a discussion of unsolved problems, such as lack of biomarkers, drug resistance, and adverse events, for which a solution is necessary in order to improve the benefit of anti-angiogenic drugs in the future. RESULTS: Anti-angiogenic therapy is extensively used...... in the treatment of cancer. There is evidence that drug-induced hypertension serves as a biomarker for a good response to therapy. Currently several possible anti-angiogenic biomarkers are under discussion. Further examples are changes in VEGF or interleukin [IL]-8 polymorphisms, changed plasma levels of VEGF......, or tumor microvessel density. To overcome therapy-associated problems, more research for valid biomarkers is necessary. In addition, a strategy to overcome resistance problems and severe adverse events is desirable.

    To tackle the global TB epidemic effectively, novel treatment strategies are critically needed to shorten the duration of TB therapy and treat drug-resistant TB. Drug development for TB, stymied for decades, has enjoyed a renaissance over the past several years. However, the development of new TB regimens is hindered by the limitations in our understanding and use of preclinical models; the paucity of accurate, early surrogate markers of cure, and challenges in untangling the individual contributions of drugs to multidrug regimens in a complex, multi-compartment disease. Lack of profit motive, advocacy, and imagination has contributed mightily to the dearth of drugs we have on the shelf to treat this ancient disease. Areas that will speed the development of new regimens for TB include novel murine and in vitro pharmacodynamics models, clinical endpoints that are not culture-based, innovative clinical trial designs, and an infusion of much-needed funding.

  12. Assessing mixed waste treatment technologies

    International Nuclear Information System (INIS)

    The US Department of Energy (DOE) is responsible for the management and treatment of its mixed low-level wastes (MLLW). As discussed earlier in this conference MLLW are regulated under both the Resource Conservation and Recovery Act and various DOE orders. During the next 5 years, DOE will manage over 1,200,000 m3 of MLLW and mixed transuranic (MTRU) waste at 50 sites in 22 states (see Table 1). The difference between MLLW and MTRU waste is in the concentration of elements that have a higher atomic weight than uranium. Nearly all of this waste will be located at 13 sites. More than 1400 individual mixed waste streams exist with different chemical and physical matrices containing a wide range of both hazardous and radioactive contaminants. Their containment and packaging vary widely (e.g., drums, bins, boxes, and buried waste). This heterogeneity in both packaging and waste stream constituents makes characterization difficult, which results in costly sampling and analytical procedures and increased risk to workers

  13. Targeting the treatment of drug abuse with molecular imaging

    International Nuclear Information System (INIS)

    Although imaging studies in and of themselves have significant contributions to the study of human behavior, imaging in drug abuse has a much broader agenda. Drugs of abuse bind to molecules in specific parts of the brain in order to produce their effects. Positron emission tomography (PET) provides a unique opportunity to track this process, capturing the kinetics with which an abused compound is transported to its site of action. The specific examples discussed here were chosen to illustrate how PET can be used to map the regional distribution and kinetics of compounds that may or may not have abuse liability. We also discussed some morphological and functional changes associated with drug abuse and different stages of recovery following abstinence. PET measurements of functional changes in the brain have also led to the development of several treatment strategies, one of which is discussed in detail here. Information such as this becomes more than a matter of academic interest. Such knowledge can provide the bases for anticipating which compounds may be abused and which may not. It can also be used to identify biological markers or changes in brain function that are associated with progression from drug use to drug abuse and also to stage the recovery process. This new knowledge can guide legislative initiatives on the optimal duration of mandatory treatment stays, promoting long-lasting abstinence and greatly reducing the societal burden of drug abuse. Imaging can also give some insights into potential pharmacotherapeutic targets to manage the reinforcing effects of addictive compounds, as well as into protective strategies to minimize their toxic consequences

    Full Text Available Glutamate plays a pivotal role in drug addiction, and the N-methyl-D-aspartate (NMDA glutamate receptor subtype serves as a molecular target for several drugs of abuse. In this review, we will provide an overview of NMDA receptor structure and function, followed by a review of the mechanism of action, clinical efficacy, and side effect profile of NMDA receptor ligands that are currently in use or being explored for the treatment of drug addiction. These ligands include the NMDA receptor modulators memantine and acamprosate, as well as the partial NMDA agonist D-cycloserine. Data collected to date suggest that direct NMDA receptor modulators have relatively limited efficacy in the treatment of drug addiction, and that partial agonism of NMDA receptors may have some efficacy with regards to extinction learning during cue exposure therapy. However, the lack of consistency in results to date clearly indicates that additional studies are needed, as are studies examining novel ligands with indirect mechanisms for altering NMDA receptor function.

    Bisphosphonates have been widely used in the treatment of osteoporosis with robust data from many placebo-controlled trials demonstrating its efficacy in fracture risk reduction over 3 to 5 years of treatment. Although bisphosphonates are generally safe and well tolerated, concerns have emerged about the adverse effects related to its long-term use, including osteonecrosis of the jaw and atypical femur fractures. Because bisphosphonates are incorporated into the skeleton and continue to exert an anti-resorptive effect for a period of time after the discontinuation of drugs, the concept of a "drug holiday" has emerged, whereby the risk of adverse effects might be decreased while the patient still benefits from anti-fracture efficacy. As randomized clinical trial evidence is not yet available on who may qualify for a drug holiday, there is considerable controversy regarding the selection of candidates for the drug holiday and monitoring during a drug holiday, both of which should be based on individual assessments of risk and benefit. This statement will provide suggestions for clinicians in South Korea on the identification of possible candidates and monitoring during a bisphosphonate drug holiday. PMID:26713307

  1. Biometrical issues in the analysis of adverse events within the benefit assessment of drugs.

    2016-07-01

    The analysis of adverse events plays an important role in the benefit assessment of drugs. Consequently, results on adverse events are an integral part of reimbursement dossiers submitted by pharmaceutical companies to health policy decision-makers. Methods applied in the analysis of adverse events commonly include simple standard methods for contingency tables. However, the results produced may be misleading if observations are censored at the time of discontinuation due to treatment switching or noncompliance, resulting in unequal follow-up periods. In this paper, we present examples to show that the application of inadequate methods for the analysis of adverse events in the reimbursement dossier can lead to a downgrading of the evidence on a drug's benefit in the subsequent assessment, as greater harm from the drug cannot be excluded with sufficient certainty. Legal regulations on the benefit assessment of drugs in Germany are presented, in particular, with regard to the analysis of adverse events. Differences in safety considerations between the drug approval process and the benefit assessment are discussed. We show that the naive application of simple proportions in reimbursement dossiers frequently leads to uninterpretable results if observations are censored and the average follow-up periods differ between treatment groups. Likewise, the application of incidence rates may be misleading in the case of recurrent events and unequal follow-up periods. To allow for an appropriate benefit assessment of drugs, adequate survival time methods accounting for time dependencies and duration of follow-up are required, not only for time-to-event efficacy endpoints but also for adverse events. © 2016 The Authors.

    Full Text Available Abstract Background Throughout Africa, the private retail sector has been recognised as an important source of antimalarial treatment, complementing formal health services. However, the quality of advice and treatment at private outlets is a widespread concern, especially with the introduction of artemisinin-based combination therapies (ACTs. As a result, ACTs are often deployed exclusively through public health facilities, potentially leading to poorer access among parts of the population. This research aimed at assessing the performance of the retail sector in rural Tanzania. Such information is urgently required to improve and broaden delivery channels for life-saving drugs. Methods During a comprehensive shop census in the districts of Kilombero and Ulanga, Tanzania, we interviewed 489 shopkeepers about their knowledge of malaria and malaria treatment. A complementary mystery shoppers study was conducted in 118 retail outlets in order to assess the vendors' drug selling practices. Both studies included drug stores as well as general shops. Results Shopkeepers in drug stores were able to name more malaria symptoms and were more knowledgeable about malaria treatment than their peers in general shops. In drug stores, 52% mentioned the correct child-dosage of sulphadoxine-pyrimethamine (SP compared to only 3% in general shops. In drug stores, mystery shoppers were more likely to receive an appropriate treatment (OR = 9.6, but at an approximately seven times higher price. Overall, adults were more often sold an antimalarial than children (OR = 11.3. On the other hand, general shopkeepers were often ready to refer especially children to a higher level if they felt unable to manage the case. Conclusion The quality of malaria case-management in the retail sector is not satisfactory. Drug stores should be supported and empowered to provide correct malaria-treatment with drugs they are allowed to dispense. At the same time, the role of general shops

    Full Text Available Abstract Background Within a ten year period South Africa has developed a substantial illicit drug market. Data on HIV risk among drug using populations clearly indicate high levels of HIV risk behaviour due to the sharing of injecting equipment and/or drug-related unprotected sex. While there is international evidence on and experience with adequate responses, limited responses addressing drug use and drug-use-related HIV and other health risks are witnessed in South Africa. This study aimed to explore the emerging problem of drug-related HIV transmission and to stimulate the development of adequate health services for the drug users, by linking international expertise and local research. Methods A Rapid Assessment and Response (RAR methodology was adopted for the study. For individual and focus group interviews a semi-structured questionnaire was utilised that addressed key issues. Interviews were conducted with a total of 84 key informant (KI participants, 63 drug user KI participants (49 males, 14 females and 21 KI service providers (8 male, 13 female. Results and Discussion Adverse living conditions and poor education levels were cited as making access to treatment harder, especially for those living in disadvantaged areas. Heroin was found to be the substance most available and used in a problematic way within the Pretoria area. Participants were not fully aware of the concrete health risks involved in drug use, and the vague ideas held appear not to allow for concrete measures to protect themselves. Knowledge with regards to substance related HIV/AIDS transmission is not yet widespread, with some information sources disseminating incorrect or unspecific information. Conclusions The implementation of pragmatic harm-reduction and other evidence-based public health care policies that are designed to reduce the harmful consequences associated with substance use and HIV/AIDS should be considered. HIV testing and treatment services also need to

    The prevalence of diabetes mellitus type 2 is rapidly growing. It is the cardiovascular mortality and morbidity why these patients suffer. Also heart failure becomes very frequent in diabetics, as it is a strong risk factor for development of heart failure and for its progression. Recently published data of EMPA-REG OUTCOME trial with empagliflozin hint to the possibility of heart failure treatment with this drug. The author presents data about the influence of antidiabetic drugs on cardiovascular risk factors, specifically on heart failure. This can be a way how to prevent heart failure in diabetic patients. Later he presents data about the influence of antidiabetics on symptoms and signs of heart failure. Some of these drugs are neutral, some are risky for patients and in the case of empagliflozin there is a beneficial influence. As heart failure is a great problem of clinical practice and diabetes is a strong risk factor of heart failure, we are looking also for prevention of heart failure and for its treatment also by using antidiabetic drug.

    Aims. The introduction of second generation antipsychotic (SGA) medication over a decade ago led to changes in prescribing practices; these drugs have eclipsed their predecessors as treatments for schizophrenia. However, the metabolic side effects of these newer antipsychotics have been marked and there are increasing concerns as to whether these novel drugs really are superior to their predecessors in terms of the balance between risks and benefits. In this article, we review the literature regarding comparisons between first generation antipsychotic (FGA) and SGA in terms of clinical effectiveness. Methods. Large (n > 150) randomized-controlled trials (RCTs) comparing the effectiveness (efficacy and side effects) of FGA and SGA medications other than clozapine were reviewed, as were meta-analyses that included smaller studies. Results. The superiority in efficacy and reduced extrapyramidal side effects (EPSE) of SGAs is modest, especially when compared with low-dose FGAs. However, the high risk of weight gain and other metabolic disturbances associated with certain SGAs such as olanzapine is markedly higher than the risk with FGAs at the doses used in the trials. Conclusions. The efficacy profiles of various FGAs and SGAs are relatively similar, but their side effects vary between and within classes. Overall, large pragmatic trials of clinical effectiveness indicate that the care used in prescribing and managing drug treatments to ensure tolerability may be more important than the class of drug used.

    The statutory standards underlying the activities of the FDA, and the problems the Agency faces in decision making are discussed from a legal point of view. The premarketing clearance of new drugs and of food additives, the two most publicized and criticized areas of FDA activity, are used as illustrations. The importance of statutory standards in technology assessment in a regulatory setting is developed. The difficulties inherent in the formulation of meaningful standards are recognized. For foods, the words of the statute are inadequate, and for drugs, a statutory recognition of the various other objectives would be useful to the regulator and the regulated.

    Full Text Available Abstract Background Alcohol and drug use is known to be a major factor affecting the incidence of traumatic injury. However, the ways in which immediate pre-injury substance use affects patients' clinical care and outcomes remains unclear. The goal of the present study is to determine the associations between pre-injury use of alcohol or drugs and patient injury severity, hospital course, and clinical outcome. Materials and methods This study used more than 200,000 records from the National Trauma Data Bank (NTDB, which is the largest trauma registry in the United States. Incidents in the NTDB were placed into one of four classes: alcohol related, drug related, alcohol-and-drug related, and substance negative. Logistic regression models were used to determine comorbid conditions or treatment complications that were significantly associated with pre-injury substance use. Hospital charges were associated with the presence or absence of drugs and alcohol, and patient outcomes were assessed using discharge disposition as delimited by the NTDB. Results The rates of complications arising during treatment were 8.3, 10.9, 9.9 and 8.6 per one hundred incidents in the alcohol related, drug related, alcohol-and-drug related, and substance-negative classes, respectively. Regression models suggested that pre-injury alcohol use is associated with a 15% higher risk of infection, whereas pre-injury drug use is associated with a 30% higher risk of infection. Pre-injury substance use did not appear to significantly impact clinical outcomes following treatment for traumatic injury, however. Conclusion This study suggests that pre-injury drug use is associated with a significantly higher complication rate. In particular, infection during hospitalization is a significant risk for both alcohol and drug related trauma visits, and drug-related trauma incidents are associated with increased risk for additional circulatory complications.

  11. Rebound effect of drugs: fatal risk of conventional treatment and pharmacological basis of homeopathic treatment

    Directory of Open Access Journals (Sweden)

    Marcus Zulian Teixeira

    2012-06-01

    Full Text Available The homeopathic model applies the secondary action or vital reaction of the organism as a therapeutic method and thus prescribes treatment by similitude, which consists in administering to ill individuals substances that cause similar symptoms in healthy individuals. The vital, homeostatic or paradoxical reaction of the organism might be explained scientifically by means of the rebound effect of modern drugs, which might cause fatal iatrogenic events after discontinuation of antipathic (a term used in alternative medicine for palliative treatment, also known as enantiopathic treatment. Although the rebound effect is studied by modern pharmacology, it is poorly communicated to and discussed among healthcare professionals, who are thus deprived of information needed for the safe management of modern drugs. This article presents an up-to-date review on the rebound effect of modern drugs that grounds the homeopathic principle of healing and calls the attention of doctors to this type of adverse effect that is usually unnoticed. The rebound effect of modern palliative drugs, which was pointed out by Hahnemann more than two centuries ago, might cause fatal adverse events and is illustrated by the examples of acetylsalicylic acid, anti-inflammatory agents, bronchodilators, antidepressants, statins, proton-pump inhibitors, etc. Although the rebound effect is expressed by a small fraction of (susceptible individuals and might be avoided by gradual tapering of antipathic drugs, it exhibits epidemiologic importance as a function of the massive use of such palliative drugs and the lack of knowledge in its regard.

    Traditional chemotherapy used today at clinics is mainly inherited from the thinking and designs made four decades ago when the Cancer War was declared. The potency of those chemotherapy drugs on in-vitro cancer cells is clearly demonstrated at even nanomolar levels. However, due to their non-specific effects in the body on normal tissues, these drugs cause toxicity, deteriorate patient's life quality, weaken the host immunosurveillance system, and result in an irreversible damage to human's own recovery power. Owing to their unique physical and biological properties, nanotechnology-based chemotherapies seem to have an ability to specifically and safely reach tumor foci with enhanced efficacy and low toxicity. Herein, we comprehensively examine the current nanotechnology-based pharmaceutical platforms and strategies for intelligent design of new nanomedicines based on targeted drug delivery system (TDDS) for cancer metastasis treatment, analyze the pros and cons of nanomedicines versus traditional chemotherapy, and evaluate the importance that nanomaterials can bring in to significantly improve cancer metastasis treatment.

    Full Text Available PURPOSE: PEGylated liposomes are important drug carriers that can passively target tumor by enhanced permeability and retention (EPR effect in neoplasm lesions. This study demonstrated that tumor burden determines the tumor uptake, and also the tumor response, in cancer treatment with PEGylated liposomal drugs in a C26/tk-luc colon carcinoma-bearing mouse model. METHODS: Empty PEGylated liposomes (NanoX and those encapsulated with VNB (NanoVNB were labeled with In-111 to obtain InNanoX and InVNBL in high labeling yield and radiochemical purity (all >90%. BALB/c mice bearing either small (58.4±8.0 mm(3 or large (102.4±22.0 mm(3 C26/tk-luc tumors in the right dorsal flank were intravenously administered with NanoVNB, InNanoX, InVNBL, or NanoX as a control, every 7 days for 3 times. The therapeutic efficacy was evaluated by body weight loss, tumor growth inhibition (using calipers and bioluminescence imaging and survival fraction. The scintigraphic imaging of tumor mouse was performed during and after treatment. RESULTS: The biodistribution study of InVNBL revealed a clear inverse correlation (r (2 = 0.9336 between the tumor uptake and the tumor mass ranged from 27.6 to 623.9 mg. All three liposomal drugs showed better therapeutic efficacy in small-tumor mice than in large-tumor mice. Tumor-bearing mice treated with InVNBL (a combination drug showed the highest tumor growth inhibition rate and survival fraction compared to those treated with NanoVNB (chemodrug only and InNanoX (radionuclide only. Specific tumor targeting and significantly increased tumor uptake after periodical treatment with InVNBL were evidenced by scintigraphic imaging, especially in mice bearing small tumors. CONCLUSION: The significant differences in the outcomes of cancer treatment and molecular imaging between animals bearing small and large tumors revealed that tumor burden is a critical and discriminative factor in cancer therapy using PEGylated liposomal drugs.

  15. Drug Treatment of Venous Thromboembolism in the Elderly.

    Science.gov (United States)

    Boey, Jir Ping; Gallus, Alexander

    2016-07-01

    Half of all patients with acute venous thromboembolism are aged over 70 years; they then face the added hazard of an age-related increase in the incidence of major bleeding. This makes it even more important to weigh the balance of benefit and risk when considering anticoagulant treatment and treatment duration. Traditional treatment with a heparin (usually low molecular weight) followed by a vitamin K antagonist such as warfarin is effective but is often complicated, especially in the elderly. The direct-acting oral anticoagulants (DOACs), i.e. the thrombin inhibitor dabigatran and the factor Xa inhibitors rivaroxaban, apixaban and edoxaban, are given in fixed doses, do not need laboratory monitoring, have fewer drug-drug interactions and are therefore much easier to take. Randomised trials, their meta-analyses and 'real-world' data indicate the DOACs are no less effective than warfarin (are non-inferior) and probably cause less major bleeding (especially intracranial). It seems the relative safety of DOACs extends to age above 65 or 70 years, although bleeding becomes more likely regardless of the chosen anticoagulant. Renal impairment, comorbidities (especially cancer) and interventions are special hazards. Ways to minimise bleeding include patient selection and follow-up, education about venous thromboembolism, anticoagulants, drug interactions, regular checks on adherence and avoiding needlessly prolonged treatment. The relatively short circulating half-lives of DOACs mean that time, local measures and supportive care are the main response to major bleeding. They also simplify the management of invasive interventions. An antidote for dabigatran, idarucizumab, was recently approved by regulators, and a general antidote for factor Xa inhibitors is in advanced development. PMID:27255713

    LCZ696 is a first-in-class angiotensin receptor neprilysin inhibitor in development for treatments of hypertension and heart failure indications. In 3 separate studies, pharmacokinetic drug-drug interactions (DDIs) potential was assessed when LCZ696 was coadministered with hydrochlorothiazide (HCTZ), amlodipine, or carvedilol. The studies used a open-label, single-sequence, 3-period, crossover design in healthy subjects. Blood samples were collected to determine the pharmacokinetic parameters of LCZ696 analytes (AHU377, LBQ657, and valsartan), HCTZ, amlodipine, or carvedilol (R[+]- and S[-]-carvedilol) for statistical analysis. When coadministered LCZ696 with HCTZ, the 90% CIs of the geometric mean ratios of AUCtau,ss of HCTZ and that of LBQ657 were within a 0.80-1.25 interval, whereas HCTZ Cmax,ss decreased by 26%, LBQ657 Cmax,ss increased by 19%, and the AUCtau,ss and Cmax,ss of valsartan increased by 14% and 16%, respectively. Pharmacokinetics of amlodipine, R(+)- and S(-)-carvedilol, or LBQ657 were not altered after coadministration of LCZ696 with amlodipine or carvedilol. Coadministration of LCZ696 400 mg once daily (qd) with HCTZ 25 mg qd, amlodipine 10 mg qd, or carvedilol 25 mg twice a day (bid) had no clinically relevant pharmacokinetic drug-drug interactions. LCZ696, HCTZ, amlodipine, and carvedilol were safe and well tolerated when given alone or concomitantly in the investigated studies. PMID:27137712

    The relationship between vulnerable attachment style, psychopathology, drug abuse, and retention in treatment among patients in methadone maintenance treatment (MMT) was examined by the Vulnerable Attachment Style Questionnaire (VASQ), the Symptom Checklist-90 (SCL-90), and drug abuse urine tests. After six years, retention in treatment and repeated urine test results were studied. Patients with vulnerable attachment style (a high VASQ score) had higher rates of drug abuse and higher psychopathology levels compared to patients with secure attachment style, especially on the interpersonal sensitivity, anxiety, hostility, phobic anxiety, and paranoid ideation scales. Drug abstinence at baseline was related to retention in treatment and to higher rates of drug abstinence after six years in MMT, whereas a vulnerable attachment style could not predict drug abstinence and retention in treatment. Clinical Implications concerning treatment of drug abusing populations and methodological issues concerning the VASQ's subscales are also discussed. PMID:25188703

  1. Position of anticholinergic drugs in the treatment of childhood asthma

    Directory of Open Access Journals (Sweden)

    Stojković-Anđelković Anđelka

    2010-01-01

    Full Text Available Anticholinergic drugs block muscarinic effect of acetylcholine on the receptors of postjunctional membranes and so inhibit the answer of the postganglionic parasympathetic nerve. The loss of M2 muscarinic receptors function occurs in asthmatics and it contributes to bronchial hyperresponsiveness and it is not a chronic feature of asthma, instead it characterizes asthma exacerbation. The loss of M2 muscarinic receptor function in children and adults happens during antigen bronchoprovocation or during exposition of asthmatics to ozone. After inhalation, ipratropium bromide (IB can be found in a small quantity in circulation and it links less readily to muscarinic receptors on airway smooth muscles as related to its absorption after intravenous application. In the stepwise approach of asthma inhaled anticholinergics is recommended if the symptoms of the disease cannot be adequately controlled by a regular inhalation of antiinflammatory drugs with β2-agonist and oral steroids. The improvement of the airway inspiratory capacity is more elevated than the improvement of FEV1 after inhalation of IB. IB has similar effect as salbutamol and it is recommended to control a stable chronic obstructive disease. During our numerous investigations and up-to-date experience in the usage of 5-7 μg/kg/body mass of IB repeated every 4-6 hours in combination with salbutamol, we did not notice adverse effects of the drug in infants. IB is recommended for hospital treatment of children. .

    unnecessary bureaucracy and regulation. As a student of Tom's in the 1970s in London, working on hepatoma-specific alkylating agents at Charing Cross Hospital in collaboration with his lab on the other side of town, I can attest to the fact that the regulatory hurdles to cancer drug development just twenty years later have added immeasurably to the effort and cost of cancer drug development. However, I look with optimism to the future of cancer diagnosis, prevention and treatment. It is a future where what we are learning now about the molecular and genetic basis of cancer will find their clinical outlet just as surely as the anatomic, microbial, metabolic and endocrine basis for disease has in the past. This new knowledge will provide new techniques in molecular diagnosis, which will allow us to predict which in situ cancers are destined for malignant behavior, and which can be safely watched without the need for intervention. Individual patient risk for particular cancers will be accurately predictable, so that patients can alter lifestyle habits or begin other prevention strategies. Oncogenes and growth suppressor genes give us new targets to inhibit or replace. Tumor-specific kinases will meet their inhibitors. The oncologist will play a leading role in understanding, applying and interpreting this new information in the clinic-an exciting and challenging future! PMID:10387987

  3. Attempts to develop radioactive drugs in the treatment of cancer

    International Nuclear Information System (INIS)

    As an approach to improving the treatment of patients with some types of cancer, it appears to be important to attempt to develop radioactive drugs. These are compounds which, because of their chemical structure, are concentrated selectively in the viable malignant cells of tumors and carry incorporated radioactive atoms, which are responsible for the action of the drug, in sufficiently high specific activity, to the right places, in order to produce the radiotherapeutic effect in situ, and without significant damage to normal tissues. This method has been termed ''radiochemotherapy'' and can be regarded as including ''immunoradiotherapy'' using antitumor antibodies carrying radioactive atoms and tissue-specific therapy. Other macromolecular substances, e.g., natural and synthetic RNAs, may well prove to be of interest. However, most of the compounds studied so far have a relatively low molecular weight. The radioisotope must be bound firmly in the molecule both chemically and in vivo from the point of view of metabolic changes. Only agents used in systemic therapy will be considered here; endolymphatic therapy and the uses of radioactive colloids and of radioactive microspheres will be excluded. In general, the radioactive drugs are administered by intravenous injection, though in a number of cases intraarterial therapy has also been used

    Full Text Available Background Drug abuse is a chronic and enduring phenomenon, which is among the important challenging public health problems. One of the main aspects in drug abuse is the relapse. Objectives The aims of this study were to estimate the time to relapse (survival rate and to evaluate some of its associated variables by survival analysis. Patients and Methods This research was conducted in four addiction treatment centers on 140 self-referred addicts in Ilam city, Iran, in 2012. Cluster sampling method was used for selecting the samples and data were collected by interview and referring to the subjects’ records. The gathered data were analyzed through the life table, Kaplan-Meier analysis, log rank test, and Cox regression. Results The relapse rate was 30.42%, mean and median of the time to relapse (survival time were 27.40 ± 1.63 months (CI 95%: 24.19 - 30.60 and 25 ± 2.25 months (CI 95%: 22.5 - 27.5, respectively. In the first six months, the cumulative survival rate was 83%, while in the 24th month it was 46% and the following time was consistent. Job status (OR = 2.64, marital status (OR = 1.55, family size (OR = 1.20 and age (OR = 0.23 were statistically significant in Cox regression model. Conclusions In the initial treatment, it seems necessary to supervise and monitor the treatment process through staff in addiction treatment centers together with the company of the addicts’ families to reduce relapse rate.

    Experience from two HIV-preventive projects among drug abusers in Oslo, Norway, shows that HIV-positive drug abusers carry on their drug abuse independent of visits to residential drug-free treatment or prison. HIV-positive former drug abusers show a tendency to relapse to drug abuse. In terms of HIV-prevention among drug abusers it is important to reduce injection of drugs among HIV-positive drug abusers. Thus, methadone maintenance programmes should be considered in HIV-prevention in Norway. PMID:2363170

    Although the plasma technology has long been applied to treat contact lenses, the effect of this treatment on the performance of drug-loaded contact lenses is still unclear. The objective of this work is to study the effect of nitrogen plasma treatment on two drug-loaded polymeric formulations which previously demonstrated to be suitable for therapeutic contact lenses: a poly-hydroxyethylmethacrylate (pHEMA) based hydrogel loaded with levofloxacin and a silicone-based hydrogel loaded with chlorhexidine. Modifications of the surface and the optical properties, and alterations in the drug release profiles and possible losses of the antimicrobial activities of the drugs induced by the plasma treatment were assessed. The results showed that, depending on the system and on the processing conditions, the plasma treatment may be beneficial for increasing wettability and refractive index, without degrading the lens surface. From the point of view of drug delivery, plasma irradiation at moderate power (200 W) decreased the initial release rate and the amount of released drug, maintaining the drug activity. For lower (100 W) and higher powers (300 W), almost no effect was detected because the treatment was, respectively, too soft and too aggressive for the lens materials. PMID:25234933

    2013-07-01

    Full Text Available OBJECTIVE: Willingness to pay for methadone maintenance treatment (MMT in three Vietnamese epicentres of injection-drug-driven human immunodeficiency virus (HIV infection was assessed. METHODS: A convenience sample of 1016 patients receiving HIV treatment in seven clinics was enrolled during 2012. Contingent valuation was used to assess willingness to pay. Interviewers reviewed adverse consequences of injection drug use and the benefits of MMT. Interviewers then described the government's plan to scale up MMT and the financial barriers to scale-up. Willingness to pay was assessed using double-bounded binary questions and a follow-up open-ended question. Point and interval data models were used to estimate maximum willingness to pay. FINDINGS: A total of 548 non-drug-users and 468 injection drug users were enrolled; 988 were willing to pay for MMT. Monthly mean willingness to pay among non-drug-users, 347 drug users not receiving MMT and 121 drug users receiving MMT was 10.7 United States dollars [US$] (35.7% of treatment costs, US$ 21.1 (70.3% and US$ 26.2 (87.3%, respectively (mean: US$ 15.9; 95% confidence interval, CI: 13.6-18.1. Fifty per cent of drug users were willing to pay 50% of MMT costs. Residence in households with low monthly per capita income and poor health status predicted willingness to pay less among drug users; educational level, employment status, health status and current antiretroviral therapy receipt predicted willingness to pay less among non-drug-users. CONCLUSION: Willingness to pay for MMT was very high, supporting implementation of a co-payment programme.

    The occurrence in the early 60's of stable resistance to chloroquine among Plasmodium falciparum strains in the Amazonas and on the Thai-Cambodian border has been a shock for all malariologists. This led to the search for new antimalarials without cross resistance with chloroquine. For each new drug, one of the major concerns was to define how rapidly parasites would develop resistance to this compound. Drug combinations were taken into consideration so as to achieve a delay in the appearance of resistance. The decision to test a triple combination has led to the development of Fansimef, a fixed combination with tablets containing 250 mg mefloquine, 500 mg sulfadoxine and 25 mg pyrimethamine. A very relevant delay in the development of resistance was found both in-vivo--in the P. berghei model--and in-vitro using P. falciparum. Fansimef has also been under investigations for malaria. Controlled clinical trials were performed in Africa, South America and South East Asia. The documentation for this new indication will be submitted to registration authorities in 1991. A preference alternative to continuous chemoprophylaxis is stand-by malaria treatment for travellers to regions where the malaria risk is relatively low. Stand-by treatment is under investigations in France and in Switzerland. In the search for alternative remedies against drug resistant P. falciparum malaria our attention was directed to Yingzhaosu, a new sesquiterpene peroxide of plant origin from traditional Chinese medicine. A short and convenient synthesis of this ring system gave access to a variety of structural analogues of Yingzhaosu.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1998081

    Objective Patients with generalized autoimmune dysautonomia may also present with gastroparesis. Immune dysfunction in such patients can be evaluated using antibodies to glutamic acid decarboxylase (GAD) and full thickness biopsy of stomach. In this study, we utilize immunotherapy for treatment of drug and Gastric Electrical Stimulation (GES) resistant gastroparetic patients with evidence of neuroinflammation on full thickness gastric biopsy and had positive GAD65 autoantibodies. Material and methods We conducted a retrospective chart review of 11 female patients with drug and device resistant gastroparesis. Patients were treated for a total of 8–12 weeks with either intravenous immunoglobulin (IVIg), or combined mycophenolate mofetil (MM) and methylprednisolone, or only MM. Patients were excluded if they had previous side effects from steroid therapy, low scores on dual-energy X-ray absorptiometry (DEXA) scan results, immune-compromised conditions with infections like tuberculosis and zoster. Symptoms of nausea, vomiting, abdominal pain, early satiety/anorexia, bloating and total symptom score (TSS) as reported by the patients were recorded before and after the treatment at a follow up visit 2 to 16 weeks after initiation of therapy. Results Maximum symptom improvement was seen in patients treated with IVIg (67%). 6 patients (55%) had improvement in vomiting, whereas 5 patients (45%) had improvements in nausea, abdominal pain and bloating. Conclusions Immunomodulatory therapy shows positive outcomes in improving vomiting symptom in some gastroparetic patients who have coexisting positive autoimmune profiles. This preliminary data suggests the need for further investigations in immunotherapy targeted to patients with gastroparetic symptoms refractory to approved drug and device therapies. PMID:27014566

    Full Text Available Background: Neuropathic pain (NeP manifests as chronic pain and causes significant medical and economic burden for both the individual and the society. Treatment of NeP is often symptomatic and includes single or combination drug therapy. Many drugs that are not recommended in the guidelines are also widely used. Aim: The present study was aimed at determining the annual cost of NeP treatment in Turkey and to assess the amount of resource loss due to irrational drug use and its associated complications. Methods: Each item in NeP prescriptions and their relevant costs between July 2007 and June 2009 was retrospectively analyzed. Results: The number of prescriptions for NeP was 8646358 and 9650641 for the first and second years, respectively. The irrational items were 7513299 in the first year and 8360754 in the second year. The proportion of irrational treatment cost was 48.5% for the first year and 48.6% for the second year. Total cost of these prescriptions was estimated to be 47924534 Turkish Liras and 60715905 Turkish Liras for the first and second years, respectively. The estimated irrational treatment cost of NeP together with the additional burden exceeded half of the total cost. Conclusions: Further studies on health economics perspective are needed to confirm these results. Better education of healthcare professionals and better regulations in reimbursement will help to improve this problem.

    Porous silicon (PSi) is a promising material for the delivery and sustained release of therapeutic molecules in various tissues. Due to the constant rinsing of cornea by tear solution as well as the short half-life of intravitreal drugs, the eye is an attractive target for controlled drug delivery systems, such as PSi microparticles. Inherent barriers ensure that PSi particles are retained in the eye, releasing drugs at the desired speed until they slowly break down into harmless silicic acid. Here, we have examined the in vitro cytotoxicity of positively and negatively charged thermally oxidized (TOPSi) and thermally carbonized (TCPSi) porous silicon microparticles on human corneal epithelial (HCE) and retinal pigment epithelial (ARPE-19) cells. In addition to ocular assessment under an inverted microscope, cellular viability was evaluated using the CellTiter Blue™, CellTiter Fluor™, and lactate dehydrogenase (LDH) assays. CellTiter Fluor proved to be a suitable assay but due to non-specific and interfering responses, neither CellTiter Blue nor LDH assays should be used when evaluating PSi particles. Our results suggest that the toxicity of PSi particles is concentration-dependent, but at least at concentrations less than 200μg/ml, both positively and negatively charged PSi particles are well tolerated by human corneal and retinal epithelial cells and therefore applicable for delivering drug molecules into ocular tissues.

    In glaucoma treatment, ocular devices such as drug-loaded contact lenses have recentlyemerged as preferred candidates over eyedrops. Timolol maleate (TM), a prevalent glaucoma drug, exhibits side effects when excess drug enters the systemic circulation. Unlike eyedrops and drug-soaked lenses, new designs should provide sustained release and minimize undesirable burst release. Current innovations have not addressed the important issue of drug elution from contact lens during wet storage and sh...

    Targeting dormant Mycobacterium tuberculosis represents a challenge to antituberculosis drug discovery programs. We previously reported and validated the use of the streptomycin (STR)-dependent M. tuberculosis 18b strain as a tool for assessing drug potency against nonreplicating bacteria both in vitro and in vivo. In this study, we generated a luminescent 18b strain, named 18b-Lux, by transforming the bacteria with a vector expressing the luxCDABE operon from Photorhabdus luminescens. Luciferase expression was demonstrated under replicating conditions, and, more importantly, luminescence levels significantly above background were detected following STR removal. The sensitivity of STR-starved 18b-Lux to approved and candidate antituberculosis therapeutic agents was evaluated by means of a luciferase assay in a 96-well format. Results mirrored the data obtained with the standard resazurin reduction microplate assay, and the luminescence readout allowed time course assessments of drug efficacy in vitro. Specifically, we proved that bedaquiline, the rifamycins, and sutezolid displayed time-dependent activity against dormant bacteria, while pyrazinamide and SQ109 showed bactericidal effects at the highest concentrations tested. Overall, we established the optimal conditions for an inexpensive, simple, and very sensitive assay with great potential for future applications. PMID:25896710

    Full Text Available Background: Rational drug use is a tool through which safe, effective and economic medication is provided. Rational prescribing ensures adherence to treatment and protects drug consumers from unnecessary adverse drug reactions. Rational dispensing on the other hand, promotes the safe, effective and economic use of drugs.Objectives: The aim of this study was to assess drug use practices and completeness of information on prescriptions in Gondar University Hospital.Methodology: A combination of retrospective and cross sectional study was conducted in outpatient pharmacy in the facility. Of the total of 30,000, some 1145 prescriptions containing drugs prescribed during the month of May 1, 2010 to April 30, 2011 were reviewed for retrospective and 31 patients coming with their prescriptions to outpatient pharmacy were interviewed in the middle of the week on the day of January 25, 2012.Results: The mean number of drugs per prescriptions was 1.76, percentage of prescriptions containing < 2 drugs per prescription was 80.87%. The generic name of the medication was used in 99.16 % of the prescriptions. Antibiotics were prescribed in 29.14 % of prescriptions and injections were prescribed in 28.50% of prescriptions. The drugs prescribed in 98.89% of prescriptions were part of the hospital essential drug list indicating the acceptance of this list by health care professionals. Patients age, sex and card number were written 86.64%, 67.93% and 73.54% respectively. Address of the patient and diagnosis were omitted 97.29% and 99.99% respectively. The correct name and strength of the drug were clearly stated in 80% of the prescriptions whereas dose, frequency and durations were clearly indicated in 81.38%, 76.07% and 82.01% of the prescriptions respectively. 33.42%, 96.69%, 72.56% and 16.09% of the prescriptions contain the name, signature, date and qualification of the prescribers. 80% of patients interviewed had adequate knowledge of how to take the

    AIM: To evaluate the patterns of use of clarithromycin for gastrointestinal disease treatment and promote its rational use.METHODS: Using a structured pro forma, we conducted a two-month survey of the electronic prescriptions containing immediate-release (IR) or sustained-release (SR) product of clarithromycin for outpatients with gastrointestinal diseases in a 2200-bed general hospital. Suitability of the prescription was audited retrospectively.RESULTS: One hundred and sixty-four prescriptions of SR product and 110 prescriptions of IR product were prescribed for gastrointestinal disease treatment. Among prescriptions for anti-Helicobacter pylori(H pylori) therapy, triple therapy take the dominant position (91.8%), followed by quadruple therapy (4.3%) and dual therapy (3.9%). Amoxicillin was the most frequently co-prescribed antibiotic. Furazolidone and levofloxacin are used more widely than metronidazole or tinidazole. Clarithromycin SR was administered at inappropriate time points in all prescriptions. Fifty percent of all prescriptions of clarithromycin SR, and 6.4% of prescriptions of clarithromycin IR, were prescribed at inappropriate dosing intervals. Surprisingly, disconcordance between diagnoses and indications was observed in all prescriptions of clarithromycin SR which has not been approved for treating Hpylori infection although off-label use for this purpose was reported in literature. On the contrary, only one prescription (0.9%) of clarithromycin IR was prescribed for unapproved indication (i.e. Gastro-oesophageal reflux disease). 1.4% of prescriptions for chronic gastritis or peptic ulcer treatment were irrational in that clarithromycin was not co-prescribed with gastric acid inhibitors. Clinical significant CYP3A based drug interactions with clarithromycin were identified.CONCLUSION: There is a great scope to improve the quality of clarithromycin prescribing in patients with gastrointestinal disease, especially with regard to administration

    2015-12-01

    Simple, quality-assured, child-friendly formulations of existing first-line anti-tuberculosis (TB) drugs in the correct dosages are now becoming available. Efforts are currently underway by the TB Alliance, the World Health Organization (WHO), and its partners to make appropriate medicines available to treat children diagnosed with TB. The functioning of the current market and the distribution pathways in pediatric TB drugs now require characterization and understanding in order to develop appropriate strategies for delivery of these and other future pediatric TB medicines. The Stop TB Partnership's Global Drug Facility (GDF) plays a major role in supplying pediatric TB medications worldwide. GDF is considered to be the largest procurer of pediatric TB treatment and the largest supplier to national TB programs of quality pediatric drugs. Between 2007 and 2013, the GDF delivered more than 580, 000 treatments to children in over 50 countries, 14 of which are among the 22 high TB burden countries. We analyzed this data set in the context of WHO estimates of pediatric TB as well as other available information to assess the functioning of the current market, lessons learnt from the GDF experience in the market, and opportunities for future products.

  20. Assessment and treatment of nocturnal panic attacks.

    Craske, Michelle G; Tsao, Jennie C I

    2005-06-01

    Nocturnal panic (NP), waking from sleep in a state of panic, is a common occurrence among patients with panic disorder, with 44-71% reporting at least one such attack. NP is a non-REM event that is distinct from sleep terrors, sleep apnea, nightmares or dream-induced arousals. This review outlines recent advances in the characterization of NP, as well as current approaches to the assessment and treatment of NP. In contrast to earlier work, more recent studies suggest that patients with NP do not differ from patients without NP on sleep architecture, sleep physiology, self-reported sleep quality and severity of panic disorder. However, more precise measurement of physiological precipitants and features is warranted. Assessment of NP focuses on ruling out other explanations for NP, with differential diagnosis based on interviews, sleep polysomnography and ambulatory recording of sleep. Psychological treatment (cognitive-behavioral therapy) targets misappraisals of anxiety sensations, hyperventilatory response, and conditioned reactions to internal, physical cues. Recent evidence supports the efficacy of this approach, however, controlled studies on pharmacological agents in the treatment of NP are lacking. Research is needed to examine the effects of combined cognitive-behavioral therapy and medications, compared to medication alone in the treatment of NP. PMID:15893248

    . Strategies to improve the HCV treatment rate among PWID involve pretreatment management and assessment, a multidisciplinary approach, management of side effects, and enhanced education and counseling. Conclusion: Specific factors are associated with poorer treatment outcomes in PWID on the side of both the patient and the treatment system. However, given that PWID can achieve treatment adherence and sustained virologic response rates comparable with those in nondrug users, drug use per se should not be considered a criterion for exclusion from treatment. Further development of measures leading to higher uptake of treatment and adherence in PWID and appropriate adaptation of HCV treatment guidelines represent important tools in this regard.

    2008-10-01

    Abstract Outbreaks of extensively drug-resistant tuberculosis (XDR-TB) in developing countries and recent headlines of an American traveling with a resistant variant of tuberculosis have brought XDR-TB into the spotlight. The World Health Organization and the United States Centers for Disease Control and Prevention have identified XDR-TB as a serious public health threat and are mandating increased efforts at control of tuberculosis. Although XDR-TB is believed to be no more infectious than other variants of tuberculosis, infection with and spread of XDR-TB are concerning because of the ineffectiveness, toxicity, and cost of the available tuberculosis treatment options. Pharmacists may not be aware of the recent trends in tuberculosis resistance or of the impact that they can have on educating the public about this disease. To gain a better understanding of this disease and the potential roles for pharmacists in public health awareness of tuberculosis and in the care of patients with and at risk for this disease, we undertook an extensive search of the Internet, including Web sites of tuberculosis advocacy groups, and of MEDLINE from January 1968-March 2008. Currently, XDR-TB infection is uncommon in the United States, but if history is any indication, there is a high potential for an outbreak or epidemic. The XDR-TB variant has emerged from mismanaging multidrug-resistant tuberculosis, treating tuberculosis with too few drugs, using less effective second-line drugs, and not educating patients about the dangers of nonadherence. With only limited hopes of a novel effective drug combination regimen, use of available antimycobacterial drugs needs to be optimized. Pharmacists can be key players in the prevention and treatment of tuberculosis by promoting adherence, assessing patients for risk factors for resistant disease, providing information about disease control and prevention, and monitoring for effectiveness, adverse effects, and drug interactions.

    This special issue exemplifies one of the major goals of the current editor of Experimental and Clinical Psychopharmacology (Dr. Suzette Evans): to increase the number of manuscripts that emphasize females and address sex differences. Taken together, these articles represent a broad range of drug classes and approaches spanning preclinical research to treatment to better understand the role of sex differences in drug abuse. While not all studies found sex differences, we want to emphasize that finding no sex difference is just as important as confirming one, and should be reported in peer-reviewed journals. It is our intention and hope that this special issue will further advance scientific awareness about the importance of accounting for sex differences in the study of substance abuse. Participant sex is an essential variable to consider in developing a more comprehensive understanding of substance abuse. Rather than viewing investigating sex differences as burdensome, investigators should seize this opportune area ripe for innovative research that is long overdue. PMID:26237316

    2005-01-01

    During the last decade we have witnessed substantial improvements in the therapeutic options for pulmonary arterial hypertension (PAH), including true innovations targeting some of the mechanisms involved in the pathogenesis of this devastating disease. Intravenous epoprostenol was the first drug to improve symptoms and survival of patients with PAH. Novel prostanoids, including subcutaneous treprostinil and inhaled iloprost, also have beneficial effects in many patients, although their long-term efficacy is less well known. Among the newer treatments for PAH, endothelin receptor antagonists and phosphodiesterase type 5 (PDE5) inhibitors have reshaped clinical practice. The endothelin receptor antagonist bosentan has been approved in many parts of the world and most current guidelines recommend this drug as first-line treatment for patients with PAH in functional class III. Novel endothelin receptor antagonists such as sitaxsentan sodium and ambrisentan are currently being investigated. The PDE5 sildenafil is also being intensively studied in patients with pulmonary hypertension, and most of the available data look promising, although approval for PAH is still pending. Other PDE5 inhibitors have not yet undergone extensive study in PAH. The increasing insight into the pathogenesis of PAH opens several new therapeutic opportunities, which include vasoactive intestinal peptide, selective serotonin reuptake inhibitors, adrenomedullin and HMG-CoA reductase inhibitors (statins). However, PAH is a complex disorder and targeting a single pathway can not be expected to be uniformly successful. Thus, combining substances with different modes of action is expected to improve symptoms, haemodynamics and survival in PAH patients, although combination therapy has yet to undergo the scrutiny of large randomised clinical trials.

    2016-05-01

    Torsades de pointes (TdP) is a life-threatening arrhythmia associated with prolongation of the corrected QT (QTc) interval on the electrocardiogram. More than 100 drugs available in Canada, including widely used antibiotics, antidepressants, cardiovascular drugs and many others, may cause QTc interval prolongation and TdP. Risk factors for TdP include QTc interval >500 ms, increase in QTc interval ≥60 ms from the pretreatment value, advanced age, female sex, acute myocardial infarction, heart failure with reduced ejection fraction, hypokalemia, hypomagnesemia, hypocalcemia, bradycardia, treatment with diuretics and elevated plasma concentrations of QTc interval-prolonging drugs due to drug interactions, inadequate dose adjustment of renally eliminated drugs in patients with kidney disease and rapid intravenous administration. Pharmacokinetic drug interactions associated with the highest risk of TdP include antifungal agents, macrolide antibiotics (except azithromycin) and drugs to treat human immunodeficiency virus interacting with amiodarone, disopyramide, dofetilide or pimozide. Other important pharmacokinetic interactions include antidepressants (bupropion, duloxetine, fluoxetine, paroxetine) interacting with flecainide, quinidine or thioridazine. Pharmacists play an important role in minimizing the risk of drug-induced QTc interval prolongation and TdP through knowledge of drugs that are associated with a known or possible risk of TdP, individualized assessment of risk of drug-induced QTc interval prolongation, awareness of drug interactions most likely to result in TdP and attention to dose reduction of renally eliminated QTc interval-prolonging drugs in patients with kidney disease. Treatment of hemodynamically stable TdP consists of discontinuation of the offending drug(s), correction of electrolyte abnormalities and administration of intravenous magnesium sulfate 1 to 2 g.

This study of Afghan women in drug abuse treatment (DAT centers assesses (a the extent to which these women have experienced human rights violations and mental health problems prior to entering the DAT centers, and (b whether there are specific risk factors for human rights violations among this population. A total of 176 in-person interviews were conducted with female patients admitted to three drug abuse treatment centers in Afghanistan in 2010. Nearly all women (91% reported limitations with social functioning. Further, 41% of the women indicated they had suicide ideation and 27% of the women had attempted suicide at least once 30 days prior to entering the DAT centers due to feelings of sadness or hopelessness. Half of the women (50% experienced at least one human rights violation in the past year prior to entering the DAT centers. Risk factors for human rights violations among this population include marital status, ethnicity, literacy, employment status, entering treatment based on one’s own desire, limited social functioning, and suicide attempts.

    Full Text Available Abstract Background and Objective: Resistance to antiretroviral agents is a significant concern in clinical management of HIV-infected individuals. Resistance is the result of mutations that develops in the viral protein targeted by antiretroviral agents. Material and Methods: In this cross-sectional study, the blood samples of 40 HIV-positive patients were collected. Twenty of them were drug-naïve and the rest were under treatment for at least one year by antiretroviral agents. Virus genome was extracted from patient's plasma with high-pure-viral-nucleic-acid kit. Then, by means of reverse-transcriptase and specific primers of protease genes were amplified and sequenced. Sequences of genes, drug- antiretroviral- resistant mutations and subtypes were determined using Stanford University’s HIV-drug-resistance databases. Results: Drug-naive patients show 15% resistance to nucleoside-reverse-transcriptase inhibitor (NRTI and 20% resistance to non-nucleoside-reverse-transcriptase inhibitor (NNRTI. Anti-protease resistance is not observed in any patients. In under treatment patients, drug resistance to NNRTI (25% is more than drug resistance to NRTI (20% and the rate of drug resistance to protease inhibitor is 5%. Conclusion: Our findings show a high prevalence of drug-resistant mutations in Iranian-drug-naïve-HIV-infected patients.

    Sprott, Haiko; Klauke, Wolfgang

    2013-09-01

    The treatment of chronic, non-malignant low-back pain is based on the patients' history and the clinical examination. It can be assumed that half of the cases present with a neuropathic pain component which needs to be treated with antidepressive and antiepileptic drugs instead of "pure" analgesics. Opioids should be considered with extreme caution because of their toxicity. Chronic non-malignant back pain is the prototype for interdisciplinary treatment approaches and multi-modal interdisciplinary settings, including pain programmes. However, a personalised strategy has to be preferred in most cases. A quick relief of pain is important in order to improve function as well as to re-integrate the patient into professional life. Spinal infiltrations can be of both diagnostic as well as therapeutic benefits. Their indication must be considered carefully, especially if the invasive diagnostic intervention has no therapeutic consequences. The interventional procedures should only be used as part of a multimodal approach in patients without any psychological problem. The sole use of interventions supports the purely somatic orientation of many patients and thus leads us in the wrong direction. PMID:23985154

    2007-01-01

    AIM: To review and summarize drug metabolism and its related interactions in prescribing drugs within the similar therapeutic or structural class for gastrointestinal disease treatment so as to promote rational use of medicines in clinical practice.METHODS: Relevant literature was identified by performing MEDLINE/Pubmed searches covering the period from 1988 to 2006. RESULTS: Seven classes of drugs were chosen, including gastric proton pump inhibitors, histamine H2-receptor antagonists, benzamide-type gastroprokinetic agents, selective 5-HT3 receptor antagonists, fluoroquinolones, macrolide antibiotics and azole antifungals. They showed significant differences in metabolic profile (I.e., the fraction of drug metabolized by cytochrome P450 (CYP), CYP reaction phenotype, impact of CYP genotype on interindividual pharmacokinetics variability and CYP-mediated drug-drug interaction potential). Many events of severe adverse drug reactions and treatment failures were closely related to the ignorance of the above issues. CONCLUSION: Clinicians should acquaint themselves with what kind of drug has less interpatient variability in clearance and whether to perform CYP genotyping prior to initiation of therapy. The relevant CYP knowledge helps clinicians to enhance the management of patients with gastrointestinal disease who may require treatment with polytherapeutic regimens.

  13. Drug interactions evaluation: An integrated part of risk assessment of therapeutics

    International Nuclear Information System (INIS)

    Pharmacokinetic drug interactions can lead to serious adverse events or decreased drug efficacy. The evaluation of a new molecular entity's (NME's) drug-drug interaction potential is an integral part of risk assessment during drug development and regulatory review. Alteration of activities of enzymes or transporters involved in the absorption, distribution, metabolism, or excretion of a new molecular entity by concomitant drugs may alter drug exposure, which can impact response (safety or efficacy). The recent Food and Drug Administration (FDA) draft drug interaction guidance ( (http://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/ucm072101.pdf)) highlights the methodologies and criteria that may be used to guide drug interaction evaluation by industry and regulatory agencies and to construct informative labeling for health practitioner and patients. In addition, the Food and Drug Administration established a 'Drug Development and Drug Interactions' website to provide up-to-date information regarding evaluation of drug interactions ( (http://www.fda.gov/Drugs/DevelopmentApprovalProcess/DevelopmentResources/DrugInteractionsLabeling/ucm080499.htm)). This review summarizes key elements in the FDA drug interaction guidance and new scientific developments that can guide the evaluation of drug-drug interactions during the drug development process.

    The results suggest an inverse relationship between participation in the treatment process and differential association. Previous studies have also shown that as long as the patient is present in the treatment system there is a lower risk of committing social crimes. In general, we can conclude that participation in the treatment process leads to reduction of drug abuse by increasing associations and beliefs that are against drug abuse and by negating positive attitudes towards drugs.

    2014-01-01

    The term drug-induced liver injury (DILI) describes adverse effects upon therapeutic drug treatment. They are relatively rare, affecting only 1 of 10000 - 1000000 patients, and remain mostly unpredictable. Due to development of severe hepatotoxicity or death, drugs causing DILI display a high risk for patients and have been withdrawn from the market or severely restricted in use. For the pharmaceutical industry late stage attrition due to DILI represents a big burden stretching development ti...

    Full Text Available BACKGROUND: Ongoing drug use during methadone maintenance treatment (MMT negatively affects outcomes of HIV/AIDS care and treatment for drug users. This study assessed changes in opioid use, and longitudinal predictors of continued opioid use during MMT among HIV-positive drug users in Vietnam, with the aim of identifying changes that might enhance program efficacy. METHODS: We analyze data of 370 HIV-positive drug users (mean age 29.5; 95.7% male taking MMT at multi-sites. Opioid use was assessed at baseline, 3, 6, and 9 months using interviews and heroin confirmatory urine tests. A social ecological model was applied to explore multilevel predictors of continued opioid use, including individual, interpersonal, community and service influences. Generalized estimating equations (GEE statistical models were constructed to adjust for intra-individual correlations. RESULTS: Over 9 month follow-up, self-reported opioid use and positive heroin urine test substantially decreased to 14.6% and 14.4%. MMT helped improve referrals and access to health care and social services. However, utilization of social integration services was small. GEE models determined that participants who were older (Adjusted Odd Ratio - AOR = 0.97 for 1 year increase, had economic dependents (AOR = 0.33, or were referred to TB treatment (AOR = 0.53 were less likely to continue opioid use. Significant positive predictors of ongoing opioid use included frequency of opioid use prior to MMT, peer pressure, living with sexual partners, taking antiretroviral treatment, other health concerns and TB treatment. CONCLUSION: These findings show that MMT in the Vietnamese context can dramatically reduce opioid use, which is known to be associated with reduced antiretroviral (ART adherence. Disease stage and drug interactions between antiretrovirals or TB drugs and MMT could explain some of the observed predictors of ongoing drug use; these findings could inform changes in MMT

    Drug treatment facilities are important sites for providing targeted prevention and health services to injection drug users (IDUs) who are infected with the hepatitis C virus (HCV). A nationwide survey was conducted to examine whether differences exist in the HCV-related services provided by drug treatment programs that have varying proportions of IDUs among their patients. The results indicate that, overall, drug treatment programs with a greater proportion of IDUs offer significantly more HCV services as compared to programs with a smaller proportion of IDUs. However, important components of hepatitis C-related care, such as universal basic education and counseling about HCV and extensive HCV-antibody testing, are not yet being provided by all programs with a large proportion of IDUs among their patient populations.

    Highlights: • Life cycle assessment of electronic waste recycling is quantified. • Key factors for reducing the overall environmental impact are indentified. • End-life disposal processes provide significant environmental benefits. • Efficiently reduce the improper disposal amount of e-waste is highly needed. • E-waste incineration can generate significant environmental burden. - Abstract: Life cycle assessment was conducted to estimate the environmental impact of electronic waste (e-waste) treatment. E-waste recycling with an end-life disposal scenario is environmentally beneficial because of the low environmental burden generated from human toxicity, terrestrial ecotoxicity, freshwater ecotoxicity, and marine ecotoxicity categories. Landfill and incineration technologies have a lower and higher environmental burden than the e-waste recycling with an end-life disposal scenario, respectively. The key factors in reducing the overall environmental impact of e-waste recycling are optimizing energy consumption efficiency, reducing wastewater and solid waste effluent, increasing proper e-waste treatment amount, avoiding e-waste disposal to landfill and incineration sites, and clearly defining the duties of all stakeholders (e.g., manufacturers, retailers, recycling companies, and consumers)

    Despite the high prevalence of hepatitis C virus (HCV) infection among drug users enrolled in methadone maintenance treatment programs, few drug users are being treated with combination therapy. The most significant barrier to treatment is lack of access to comprehensive HCV-related care. We describe a pilot program to integrate care for HCV infection with substance abuse treatment in a setting of maintenance treatment with methadone. This on-site, multidisciplinary model of care includes comprehensive screening and treatment for HCV infection, assessment of eligibility, counseling with regard to substance abuse, psychiatric services, HCV support groups, directly observed therapy, and enhanced linkages to a tertiary care system for diagnostic procedures. Our approach has led to high levels of adherence, with liver biopsy and substantial rates of initiation of antiviral therapy. Two cases illustrate the successful application of this model to patients with HCV infection complicated by active substance abuse and psychiatric comorbidity. PMID:15768345

    Bedaquiline, a diarylquinoline, improved cure rates when added to a multidrug-resistant tuberculosis (MDR-TB) treatment regimen in a previous placebo-controlled, phase 2 trial (TMC207-C208; NCT00449644). The current phase 2, multicenter, open-label, single-arm trial (TMC207-C209; NCT00910871) reported here was conducted to confirm the safety and efficacy of bedaquiline.Newly diagnosed or previously treated patients with MDR-TB (including pre-extensively drug-resistant (pre-XDR)-TB or extensively drug-resistant (XDR)-TB) received bedaquiline for 24 weeks with a background regimen of anti-TB drugs continued according to National TB Programme treatment guidelines. Patients were assessed during and up to 120 weeks after starting bedaquiline.Of 233 enrolled patients, 63.5% had MDR-TB, 18.9% had pre-XDR-TB and 16.3% had XDR-TB, with 87.1% having taken second-line drugs prior to enrolment. 16 patients (6.9%) died. 20 patients (8.6%) discontinued before week 24, most commonly due to adverse events or MDR-TB-related events. Adverse events were generally those commonly associated with MDR-TB treatment. In the efficacy population (n=205), culture conversion (missing outcome classified as failure) was 72.2% at 120 weeks, and 73.1%, 70.5% and 62.2% in MDR-TB, pre-XDR-TB and XDR-TB patients, respectively.Addition of bedaquiline to a background regimen was well tolerated and led to good outcomes in this clinically relevant patient cohort with MDR-TB.

    Cetirizine is indicated for the treatment of allergic conditions such as insect bites and stings, atopic and contact dermatitis, eczema, urticaria. This investigation deals with development of a novel ethosome-based topical formulation of cetirizine dihydrochloride for effective delivery. The optimised formulation consisting of drug, phospholipon 90 G™ and ethanol was characterised for drug content, entrapment efficiency, pH, vesicular size, spreadability and rheological behaviour. The ex vivo permeation studies through mice skin showed highest permeation flux (16.300 ± 0.300 µg/h/cm(2)) and skin retention (20.686 ± 0.517 µg/cm(2)) for cetirizine-loaded ethosomal vesicles as compared to conventional formulations. The in vivo pharmacodynamic evaluation of optimised formulation was assessed against oxazolone-induced atopic dermatitis (AD) in mice. The parameters evaluated were reduction in scratching score, erythema score, skin hyperplasia and dermal eosinophil count. Our results suggest that ethosomes are effective carriers for dermal delivery of antihistaminic drug, cetirizine, for the treatment of AD. PMID:24963956

  6. Epigenetics and cancer: implications for drug discovery and safety assessment

    International Nuclear Information System (INIS)

    It is necessary to determine whether chemicals or drugs have the potential to pose a threat to human health. Research conducted over the last two decades has led to the paradigm that chemicals can cause cancer either by damaging DNA or by altering cellular growth, probably via receptor-mediated changes in gene expression. However, recent evidence suggests that gene expression can be altered markedly via several diverse epigenetic mechanisms that can lead to permanent or reversible changes in cellular behavior. Key molecular events underlying these mechanisms include the alteration of DNA methylation and chromatin, and changes in the function of cell surface molecules. Thus, for example, DNA methyltransferase enzymes together with chromatin-associated proteins such as histone modifying enzymes and remodelling factors can modify the genetic code and contribute to the establishment and maintenance of altered epigenetic states. This is relevant to many types of toxicity including but not limited to cancer. In this paper, we describe the potential for interplay between genetic alteration and epigenetic changes in cell growth regulation and discuss the implications for drug discovery and safety assessment

  9. Assessing the Value of New Treatments for Hepatitis C: Are International Decision Makers Getting this Right?

    Woods, Beth; Faria, Rita; Griffin, Susan

    2016-05-01

    Health systems worldwide are facing difficult choices about the use of a series of highly effective but costly new treatments for hepatitis C. In this paper we discuss how the National Institute for Health and Care Excellence in England and Wales, the Common Drug Review in Canada and the Pharmaceutical Benefits Advisory Committee (PBAC) in Australia have approached the appraisal of these drugs. We argue that with the exception of the PBAC, assessments of the new drugs have not adequately accounted for their large financial burden. Given the potential health system impact of reimbursing these drugs, the use of lower cost-effectiveness thresholds should be considered. None of the decision-making processes included a comparison of the full range of treatment pathways. In particular, comparisons of using the new drugs as first- versus second-line drugs were omitted from all appraisals, as were comparisons with delayed treatment strategies whereby treatment is withheld until more severe disease stages. Omission of comparators leads to inaccurate estimates of cost effectiveness and potentially sub-optimal decision making. Lessons learned from these appraisals should be considered in future appraisals, particularly the upcoming assessments of the 'blockbuster' PCSK9 inhibitors for hypercholesterolaemia. PMID:26714687

    There are numerous methods available for assessing patients with Alzheimer's disease (AD) or other forms of dementia. Quality-of-life (QOL) assessment is unique among these methods. The subjective nature of quality of life provides healthcare professionals with the opportunity of incorporating the value systems of patients and their carers into their assessments. A systematic review was carried out to assess the published data (and some unpublished data) on QOL assessment tools and instruments that claim to measure quality of life in dementia. A number of measures or methods used in the literature for assessing the quality of life of patients with dementing illnesses were identified. It was decided to present the resultant review in 2 parts that correspond to the 2 main groups into which the instruments were categorised. The first (part 1), looked at measures used to assess the impact of disease as well as instruments at a developmental or testing stage. The second (part 2), includes instruments that claim to measure quality of life in studies documenting the impact of a drug in this therapeutic area. This second group consists mainly of instruments identified as being used to assess quality of life during clinical trials in dementia/AD. As in part 1, this part of the review was unable to identify any validated methods of assessing the quality of life of both patients with dementia and their carers at the same time. The ideal instrument must show that it can reliably, reproducibly and comprehensively assess quality of life for both patients with dementia and their carers. It should also demonstrate that it can measure quality of life effectively using a practical administration technique that does not place any unnecessary burden on either informal carers, other healthcare workers involved or the patient themselves. In addition, any measure intended for use in assessing the impact of drug treatment on quality of life must demonstrate sensitivity to change, also

    Objective: Investigations of injecting drug users (IDUs have suggested that the social context may influence high-risk behaviours in this population. The aim of this study was to describe knowledge, attitudes and behaviours of IDUs attending public drug-treatment centres in our area.

    Study design and methods: A cross-sectional survey was conducted between July 2002 and February 2004, enrolling 607 drug users attending four public drug-treatment centres in the Palermo area. Two of them were located inside the urban area, whereas the other two were in rural districts near the city. All participants answered an anonymous questionnaire concerning social and demographic characteristic and potential high-risk behaviours.

    Results: IDUs living in urban context have a higher educational level, higher number of sexual partners, as well as a lower prevalence of exchanging sex for drugs. Conversely, IDUs living in suburban/rural context are less likely to share syringes and more likely to have used light drugs in the past. Suburban/rural IDUs drink more alcohol but smoke less cigarettes/day, although both groups are strong smokers.

    Conclusions: The results suggest that public drug-treatment centres should take in consideration the adoption of specific programs targeting specific groups, in line with the profile and needs of the subjects in each context in order to promote approaches leading to risk reduction.

    Rats were treated with 5 different drugs p-ethoxyacetanilide (I), indometacin (II) and nor-amidopyrine-methanesulfonate (III), O,O'-bis(diethylaminoethyl)hexestrol(IV) and choloroquine (V) for 3 - 4 weeks. Liver cell fractions were isolated by discontinuous gradient centrifugation and the specific activity of acid phosphatase was determined in each. Lysosomal fractions contained widely varying amounts of this marker enzyme, indicating that the concentration of lysosomes within these fractions differed. The amounts and patterns of phospholipids reflected this fact. Since we assumed bis(monoacylglycero)phosphate [(MAG)2-P; synonym:lysobisphosphatidic acid] is a marker lipid for secondary lysosomes, we expected and found significant quantities of this acidic phospholipid only in those lysosomal fractions which were also rich in acid phosphatase activity. 12% of the lysosomal phospholipids from animals receiving the hexestrol derivative (IV), and 19% of those from the chloroquine (V) experiment were present as (MAG)2P. The fatty acid compositions of this lysosomal phospholipid were not the same in all lysosome fractions. The more (MAG)2P present in the lysosomes, the more unsaturated are the fatty acids. Thus, after treatment with chloroquine, more than 90% of the fatty acids from (MAG)2P are unsaturated; C22:6 represents about 70% of the total. PMID:627402

    Full Text Available Background: The quality of pharmacotherapy is highly dependent on the process of choosing a drug in relation to nature of the disease. Several factors should be considered in choosing optimal pharmacotherapeutics strategy including efficacy, safety, availability and cost of the drugs. The objective of this study was to assess potential drug-drug interactions and risk factors in outpatients taking cardiovascular drugs at Jimma University specialized hospital. Methods: A cross-sectional study was conducted from Feb. to April, 2011on patients visiting the cardiac clinic of Jimma University Specialized hospital. A sample of 332 outpatients who were taking cardiovascular medications at study clinic was studied. MicroMedex software was used to screen drug-drug interactions and SPSS for windows software versions-16.0 was used for data analysis. Results: A total of 1249 drugs with average of 3.76 drugs per prescription were prescribed for the 332 patients. The frequency of potential DDIs was found to be 241 (72.6%. Among these 200 (67.3% were of "moderate" severity and 164 (55.2% were delayed in onset. The most common potential DDI observed was between Enalapril and Furosemide (20%. Patients who prescribed many drugs (AOR=4.09; P=0.00 by medical intern had a higher risk of developing potential DDIs (AOR=4.6; P=0.00. Conclusions: Patients with cardiovascular disorders are subjected to high risk of potential drug-drug interactions and the number of drugs prescribed and educational level of the prescribers has a high significantly associated with the occurrence of potential drug-drug interactions. Therefore, it is imperative that further studies need to be conducted to identify reasons for and tackle the problem and provide appropriate mechanisms for management.

    IMPORTANCE New data and therapeutic options warrant updated recommendations for the use of antiretroviral drugs (ARVs) to treat or to prevent HIV infection in adults. OBJECTIVE To provide updated recommendations for the use of antiretroviral therapy in adults (aged ≥18 years) with established HIV infection, including when to start treatment, initial regimens, and changing regimens, along with recommendations for using ARVs for preventing HIV among those at risk, including preexposure and postexposure prophylaxis. EVIDENCE REVIEW A panel of experts in HIV research and patient care convened by the International Antiviral Society-USA reviewed data published in peer-reviewed journals, presented by regulatory agencies, or presented as conference abstracts at peer-reviewed scientific conferences since the 2014 report, for new data or evidence that would change previous recommendations or their ratings. Comprehensive literature searches were conducted in the PubMed and EMBASE databases through April 2016. Recommendations were by consensus, and each recommendation was rated by strength and quality of the evidence. FINDINGS Newer data support the widely accepted recommendation that antiretroviral therapy should be started in all individuals with HIV infection with detectable viremia regardless of CD4 cell count. Recommended optimal initial regimens for most patients are 2 nucleoside reverse transcriptase inhibitors (NRTIs) plus an integrase strand transfer inhibitor (InSTI). Other effective regimens include nonnucleoside reverse transcriptase inhibitors or boosted protease inhibitors with 2 NRTIs. Recommendations for special populations and in the settings of opportunistic infections and concomitant conditions are provided. Reasons for switching therapy include convenience, tolerability, simplification, anticipation of potential new drug interactions, pregnancy or plans for pregnancy, elimination of food restrictions, virologic failure, or drug toxicities.

    Tuberculosis (TB) remains a significant cause of death worldwide, and emergence of drug-resistant TB requires lengthy treatments with toxic drugs that are less effective than their first-line equivalents. New treatments are urgently needed. Delamanid, previously OPC-67863, is a novel drug of the dihydro-nitroimidazole class with potent anti-TB activity and great promise to be effective in the treatment of drug-resistant TB. This review examines the preclinical and clinical development of delamanid, reviews current guidance on its use and evaluates the opportunities and challenges for its future role in TB management.

  3. Assessments for High Dose Radionuclide Therapy Treatment Planning

    International Nuclear Information System (INIS)

    Advances in the biotechnology of cell-specific targeting of cancer, and the increased number of clinical trials involving treatment of cancer patients with radiolabeled antibodies, peptides, and similar delivery vehicles have led to an increase in the number of high-dose radionuclide therapy procedures. Optimized radionuclide therapy for cancer treatment is based on the concept of absorbed dose to the dose-limiting normal organ or tissue. The limiting normal tissue is often the red marrow, but it may sometimes be lungs, liver, intestinal tract, or kidneys. Appropriate treatment planning requires assessment of radiation dose to several internal organs and tissues, and usually involves biodistribution studies in the patient using a tracer amount of radionuclide bound to the targeting agent and imaged at sequential time points using a planar gamma camera. Time-activity curves are developed from the imaging data for the major organs tissues of concern, for the whole body, and sometimes for selected tumors. Patient-specific factors often require that dose estimates be customized for each patient. The Food and Drug Administration regulates the experimental use of investigational new drugs and requires reasonable calculation of radiation absorbed dose to the whole body and to critical organs using methods prescribed by the Medical Internal Radiation Dose (MIRD) Committee of the Society of Nuclear Medicine. Review of high-dose studies in the U.S. and elsewhere shows that (1) some studies are conducted with minimal dosimetry, (2) the marrow dose is difficult to establish and is subject to large uncertainties, and (3) despite the general availability of MIRD software, internal dosimetry methods are often inconsistent from one clinical center to another

Appropriate treatment planning requires assessment of radiation dose to several internal organs and tissues, and usually involves biodistribution studies in the patient using a tracer amount of radionuclide bound to the targeting agent and imaged at sequential timepoints using a planar gamma camera. Time-activity curves are developed from the imaging data for the major organ tissues of concern, for the whole body and sometimes for selected tumours. Patient specific factors often require that dose estimates be customised for each patient. In the United States, the Food and Drug Administration regulates the experimental use of investigational new drugs and requires 'reasonable calculation of radiation absorbed dose to the whole body and to critical organs' using the methods prescribed by the Medical Internal Radiation Dose (MIRD) Committee of the Society of Nuclear Medicine. Review of high dose studies shows that some are conducted with minimal dosimetry, that the marrow dose is difficult to establish and is subject to large uncertainties. Despite the general availability of software, internal dosimetry methods often seem to be inconsistent from one clinical centre to another. (author)

    Introduction. Earlier reviews regarding the effectiveness of Drug Treatment Courts (DTCs) reported a reduction in reoffending and substance use. Although substance users suffer from other difficulties than drug use and judicial issues, none of these reviews focused on outcomes or effects of DTCs on drug-related life domains, such as social relationships, employment, or health. Therefor, the present paper aims to review the impact of adult DTCs on substance use and drug-related life domains. M...

    We have published that pharmacological induction of oxidative stress (OS) causes anxiety-like behavior in rats. Using animal models, we also have established that psychological stress induces OS and leads to anxiety-like behaviors. All evidence points towards the causal role of OS in anxiety-like behaviors. To fully ascertain the role of OS in anxiety-like behaviors, it is reasonable to test whether the pro-anxiety effects of anxiogenic drugs caffeine or N-methyl-beta-carboline-3-carboxamide (FG-7142) can be mitigated using agents that minimize OS. In this study, osmotic pumps were either filled with antioxidant tempol or saline. The pumps were attached to the catheter leading to the brain cannula and inserted into the subcutaneous pocket in the back pocket of the rat. Continuous i.c.v. infusion of saline or tempol in the lateral ventricle of the brain (4.3mmol/day) was maintained for 1 week. Rats were intraperitoneally injected either with saline or an anxiogenic drug one at a time. Two hours later all groups were subjected to behavioral assessments. Anxiety-like behavior tests (open-field, light-dark and elevated plus maze) suggested that tempol prevented anxiogenic drug-induced anxiety-like behavior in rats. Furthermore, anxiogenic drug-induced increase in stress examined via plasma corticosterone and increased oxidative stress levels assessed via plasma 8-isoprostane were prevented with tempol treatment. Protein carbonylation assay also suggested preventive effect of tempol in the prefrontal cortex brain region of rats. Antioxidant protein expression and pro-inflammatory cytokine levels indicate compromised antioxidant defense as well as an imbalance of inflammatory response. PMID:25793256

    We investigated relationships between drinking, other drug use, and drug craving, using ecological momentary assessment (EMA), in a sample of polydrug users who were not heavy drinkers. In a prospective longitudinal cohort study, 114 heroin and cocaine users on methadone-maintenance treatment carried handheld electronic diaries during waking hours and were screened for drug and alcohol use for up to 25 weeks. Individuals who fulfilled the Diagnostic and Statistical Manual of Mental Disorders criteria for alcohol abuse or dependence were excluded. Participants responded to 2-5 random prompts per day to report on their moods, cravings, and activities and initiated entries when they used or acutely craved heroin or cocaine. Drinking alcohol was assessed in both types of entries. Breath alcohol was measured three times weekly. Participants reported drinking alcohol in 1.6% of random-prompt entries, 3.7% of event-contingent entries when craving cocaine and/or heroin, and 11.6% of event-contingent entries when using cocaine and/or heroin. Alcohol drinking was also associated with higher craving ratings and prestudy alcohol use. More drinking was detected by ambulatory self-report than by in-clinic breath testing. Even though we had screened out heavy drinkers from our sample of polydrug users, drinking was associated with heroin and cocaine craving and actual use. PMID:27579810

    Ninnemann, Andrew L; Lechner, William V; Borges, Allison; Lejuez, C W

    2016-12-01

    Contingency management (CM) is an effective treatment for substance use dependence. Within CM, rewards or vouchers promote continued abstinence by acting as alternative reinforcers to substance use. However, CM relies on the use of accurate biochemical verification methods, such as urinalysis, to verify abstinence. Synthetic cannabinoids (SCs) pose a risk for CM treatment because they are not easily detected by common urinalysis techniques. Although SCs pose a risk, there is limited information regarding current rates of SC use within substance dependent populations as well as rates of substance use and psychiatric disorders among those who use SCs in treatment. We discuss emerging research on these topics and potential implications for CM treatments. Findings suggest CM researchers should test for and query SC use among those being treated for cannabis and cocaine use problems as well as among younger populations of substance users. Implications of other novel psychoactive substances for drug treatment and drug urinalysis are also discussed. PMID:27424166

    Full Text Available Heavy use of drugs impacts of the daily activities of individuals in these activities. Several groups of investigators have indeed documented changes in cognitive performance by individuals who have a long history of chronic drug use. In the case of marijuana, a wealth of information suggests that heavy long-term use of the drug may have neurobehavioral consequences in some individuals. In humans, heavy cocaine use is accompanied by neuropathological changes that might serve as substrates for cognitive dysfunctions. Similarly, methamphetamine users suffer from cognitive abnormalities that may be consequent to alterations in structures and functions. Here, we detail the evidence for these neuropsychological consequences. The review suggests that improving the care of our patients will necessarily depend on the better characterization of drug-induced cognitive phenotypes because they might inform the development of better pharmacological and behavioral interventions, with the goal of improving cognitive functions in these subsets of drug users.

    In total, we included 14 studies with 1298 participants: nine studies (704 participants) compared CM vs. control, and five studies (594 participants) compared MIB interventions vs. control. We did not find any studies that assessed other types of psychosocial interventions. For the most part, it was unclear if included studies adequately controlled for biases within their studies as such information was not often reported. We assessed risk of bias in the included studies relating to participant selection, allocation concealment, personnel and outcome assessor blinding, and attrition. The included trials rarely captured maternal and neonatal outcomes. For studies that did measure such outcomes, no difference was observed in pre-term birth rates (RR 0.71, 95% confidence interval (CI) 0.34 to 1.51; three trials, 264 participants, moderate quality evidence), maternal toxicity at delivery (RR 1.18, 95% CI 0.52 to 2.65; two trials, 217 participants, moderate quality evidence), or low birth weight (RR 0.72, 95% CI 0.36 to 1.43; one trial, 160 participants, moderate quality evidence). However, the results did show that neonates remained in hospital for fewer days after delivery in CM intervention groups (RR -1.27, 95% CI -2.52 to -0.03; two trials, 103 participants, moderate quality evidence). There were no differences observed at the end of studies in retention or abstinence (as assessed by positive drug test at the end of treatment) in any psychosocial intervention group compared to control (Retention: RR 0.99, 95% CI 0.93 to 1.06, nine trials, 743 participants, low quality evidence; and Abstinence: RR 1.14, 95% CI 0.75 to 1.73, three trials, 367 participants, low quality evidence). These results held for both CM and MIB combined. Overall, the quality of the evidence was low to moderate. Authors’ conclusions The present evidence suggests that there is no difference in treatment outcomes to address drug use in pregnant women with use of psychosocial interventions, when

    2012-04-01

    Full Text Available Abstract Background Artemisinin-based combination therapy (ACT is currently the recommended first-line treatment for uncomplicated malaria infections. However, a significant proportion of ACT is assumed to be of poor quality, particularly in Africa. In addition, little is known about how treatment-seeking behaviour of individuals or drug price is associated with drug quality. Methods Caregivers of children less than 5 years of age were interviewed on their knowledge of malaria and their choices for treatment. Artemisinin drugs were then purchased from sellers that caregivers preferred or had previously patronized. The active ingredients were quantified by nuclear magnetic resonance spectroscopy. Results A negative relationship was anticipated between the education level of caregivers and the quality of anti-malarial drugs purchased. However, of the 33 drugs collected from 16 different shops, only one contained less than 80% of its purported active ingredient, and most drugs were within 90% of their listed amounts. No link was found between drug quality and price. Nonetheless, while ACT is the recommended first-line treatment in Ghana, 21% of the drugs collected were artemisinin monotherapy, and 27% of the ACT was not co-formulated. Among caregivers, higher education was found to be associated with both an increased likelihood of seeking treatment in a clinic first, as opposed to visiting drug shops or using herbal remedies, and with purchasing drugs from licensed sellers. Conclusion Surprisingly, drug quality was found to be uniformly high and thus no significant relationship between price, treatment-seeking behaviour and the content of the active ingredients was observed. However, artemisinin monotherapy, which the WHO considers inappropriate therapy, was still widely available in Ghana in 2010. Monotherapy was more likely to be available in unlicensed vendors where less-educated caregivers generally shopped. This linkage between education

  6. Developing artemisinin based drug combinations for the treatment of drug resistant falciparum malaria: A review

    Directory of Open Access Journals (Sweden)

    Olliaro P

    2004-01-01

    Full Text Available The emergence and spread of drug resistant malaria represents a considerable challenge to controlling malaria. To date, malaria control has relied heavily on a comparatively small number of chemically related drugs, belonging to either the quinoline or the antifolate groups. Only recently have the artemisinin derivatives been used but mostly in south east Asia. Experience has shown that resistance eventually curtails the life-span of antimalarial drugs. Controlling resistance is key to ensuring that the investment put into developing new antimalarial drugs is not wasted. Current efforts focus on research into new compounds with novel mechanisms of action, and on measures to prevent or delay resistance when drugs are introduced. Drug discovery and development are long, risky and costly ventures. Antimalarial drug development has traditionally been slow but now various private and public institutions are at work to discover and develop new compounds. Today, the antimalarial development pipeline is looking reasonably healthy. Most development relies on the quinoline, antifolate and artemisinin compounds. There is a pressing need to have effective, easy to use, affordable drugs that will last a long time. Drug combinations that have independent modes of action are seen as a way of enhancing efficacy while ensuring mutual protection against resistance. Most research work has focused on the use of artesunate combined with currently used standard drugs, namely, mefloquine, amodiaquine, sulfadoxine/pyrimethamine, and chloroquine. There is clear evidence that combinations improve efficacy without increasing toxicity. However, the absolute cure rates that are achieved by combinations vary widely and depend on the level of resistance of the standard drug. From these studies, further work is underway to produce fixed dose combinations that will be packaged in blister packs. This review will summarise current antimalarial drug developments and outline recent

    The occurrence of 8 drugs of abuse and metabolites in the influent and effluent of the 3 Wastewater Treatment Plants (WWTP) that treat wastewater from Valencia was studied in 2011, 2012 and 2013. Target drugs except 6-monoacetylmorphine (6-ACMOR) were detected in 100% of the influents. The WWTPs eliminate cocaine (COC), amphetamine (AMP), methamphetamine (MAMP) and 11-nor-9-carboxy-Δ9-tetrahydrocannabinol (THC-COOH). Benzoylecgonine (BECG) was also efficiently eliminated (93-98%), whereas 3,4-methylenedioxymethamphetamine (MDMA) presented removal rates of 32-57% and ketamine (KET) was not eliminated. The most consumed illicit drugs, according to the estimated concentrations of each compound in the studied WWTPs, were cannabis and COC followed by KET, AMP, MAMP, MDMA and heroin. Environmental risk assessment was evaluated by calculating Risk Quotient (RQ). MDMA and KET could pose a medium risk and low risk, respectively, to the aquatic organisms. Although short-term environmental risk is not worrisome, long-term effects cannot be known exactly. PMID:25108491

    Drugs of abuse and their metabolites have been recently recognized as environmental emerging organic contaminants. Assessment of their concentration in different environmental compartments is essential to evaluate their potential ecotoxicological effects. It also constitutes an indirect tool to estimate drug abuse by the population at the community level. The present work reports for the first time the occurrence of drugs of abuse and metabolites residues along the Ebro River basin (NE Spain) and also evaluates the contribution of sewage treatment plants (STPs) effluents to the presence of these chemicals in natural surface waters. Concentrations measured in influent sewage waters were used to back calculate drug usage at the community level in the main urban areas of the investigated river basin. The most ubiquitous and abundant compounds in the studied aqueous matrices were cocaine, benzoylecgonine, ephedrine and ecstasy. Lysergic compounds, heroin, its metabolite 6-monoacetyl morphine, and Delta(9)-tetradhydrocannabinol were the substances less frequently detected. Overall, total levels of the studied illicit drugs and metabolites observed in surface water (in the low ng/L range) were one and two orders of magnitude lower than those determined in effluent (in the ng/L range) and influent sewage water (microg/L range), respectively. The investigated STPs showed overall removal efficiencies between 45 and 95%. Some compounds, such as cocaine and amphetamine, were very efficiently eliminated (>90%) whereas others, such as ecstasy, methamphetamine, nor-LSD, and THC-COOH where occasionally not eliminated at all. Drug consumption estimates pointed out cocaine as the most abused drug, followed by cannabis, amphetamine, heroin, ecstasy and methamphetamine, which slightly differs from national official estimates (cannabis, followed by cocaine, ecstasy, amphetamine and heroin). Extrapolation of the consumption data obtained for the studied area to Spain points out a total

    Full Text Available Background: Tuberculosis (TB patients with a history of multiple anti-TB treatments are the ‘neglected’ group to the free anti-TB treatment policy in China. Objective: To understand the experiences of TB patients with multiple previous treatments with regard to bacteriological diagnosis and treatment regimens, especially for second-line anti-TB drugs, and how this might influence the risks of multidrug and extensively drug-resistant TB (M/XDR-TB. Design: A cross-sectional study was conducted in 10 county/district TB clinics in five provinces of China. The study participants were TB patients that had at least two previous treatment episodes that lasted longer than 1 month each. Face-to-face interviews and drug susceptibility testing (DST were conducted with the consenting participants. Results: A total of 328 TB patients were recruited. The proportion of multidrug-resistant tuberculosis (MDR-TB was 58.2% in the 287 DST-confirmed patients. Forty-two percent of the patients did not complete their first treatment course. About 23.8% of the participants had a history of taking second-line drugs, and more than 77.8% of them were treated in county TB dispensaries where only sputum microscopy was applied. Multivariate analysis found that the use of second-line drugs was significantly associated with frequency of previous treatments (p<0.01, but not with drug resistance profiles of patients. Conclusions: Patients with multiple previous treatments are at extremely high risk of MDR-TB in China. The unregulated use of second-line drugs bring about the threat of XDR-TB epidemic. DST-guided treatment and strict regulations of anti-TB treatment should be assured for the high-risk TB patients for the prevention and control of M/XDR-TB.

The key proteins in the host cells, which are related with the replication cycle of influenza virus, are regarded as potential drug targets due to their distinct advantage of lack of evolution and drug resistance. Cdc2-like kinase 1 (CLK1) in the host cells is responsible for alternative splicing of the M2 gene of influenza virus during influenza infe...

    High relapse rate of drug-dependent patients is a serious problem in the current situation. The present article describes how to design and implement virtual reality technology for drug-dependent patients with psychological treatment, with the aim at the addiction withdrawal. The software was developed based on open-source game engine for 2D models. The form of a game simulates the actual style in the day-to-day living environment of drug-dependent patients and the temptation of using drugs. The software helps the patients deal with different scenarios and different event handling, cause their own thinking, and response to the temptation from high-risk environment and from other drug-dependent patients. The function of the software is close to the real life of drug-dependent patients, and has a prospect to become a new treatment to reduce the relapse rate of drug-dependence. PMID:23469551

    The purpose of this review is to discuss recent findings related to sex differences in behavioral dyscontrol that lead to drug addiction, and clinical implications for humans are discussed. This review includes research conducted in animals and humans that reveals fundamental aspects of behavioral dyscontrol. The importance of sex differences in aspects of behavioral dyscontrol, such as impulsivity and compulsivity, is discussed as major determinants of drug addiction. Behavioral dyscontrol during adolescence is also an important consideration, as this is the time of onset for drug addiction. These vulnerability factors additively increase drug-abuse vulnerability, and they are integral aspects of addiction that covary and interact with sex differences. Sex differences in treatments for drug addiction are also reviewed in terms of their ability to modify the behavioral dyscontrol that underlies addictive behavior. Customized treatments to reduce behavioral dyscontrol are discussed, such as (1) using natural consequences such as non-drug rewards (e.g., exercise) to maintain abstinence, or using punishment as a consequence for drug use, (2) targeting factors that underlie behavioral dyscontrol, such as impulsivity or anxiety, by repurposing medications to relieve these underlying conditions, and (3) combining two or more novel behavioral or pharmacological treatments to produce additive reductions in drug seeking. Recent published work has indicated that factors contributing to behavioral dyscontrol are an important target for advancing our knowledge on the etiology of drug abuse, intervening with the drug addiction process and developing novel treatments.

    When the patent of a brand-name, marketed drug expires, new, generic products are usually offered. Small-molecule generic and originator drug products are expected to be chemically identical. Their pharmaceutical similarity can be typically assessed by simple regulatory criteria such as the expectation that the 90% confidence interval for the ratio of geometric means of some pharmacokinetic parameters be between 0.80 and 1.25. When such criteria are satisfied, the drug products are generally considered to exhibit therapeutic equivalence. They are then usually interchanged freely within individual patients. Biological drugs are complex proteins, for instance, because of their large size, intricate structure, sensitivity to environmental conditions, difficult manufacturing procedures, and the possibility of immunogenicity. Generic and brand-name biologic products can be expected to show only similarity but not identity in their various features and clinical effects. Consequently, the determination of biosimilarity is also a complicated process which involves assessment of the totality of the evidence for the close similarity of the two products. Moreover, even when biosimilarity has been established, it may not be assumed that the two biosimilar products can be automatically substituted by pharmacists. This generally requires additional, careful considerations. Without declaring interchangeability, a new product could be prescribed, i.e. it is prescribable. However, two products can be automatically substituted only if they are interchangeable. Interchangeability is a statistical term and it means that products can be used in any order in the same patient without considering the treatment history. The concepts of interchangeability and prescribability have been widely discussed in the past but only in relation to small molecule generics. In this paper we apply these concepts to biosimilars and we discuss: definitions of prescribability and interchangeability and

    Pregnancy is a state where pharmacokinetic changes are more pronounced and more rapid than during any other period of life. The consequences of such changes can be far reaching, not least in the management of epilepsy where the risks with uncontrolled seizures during pregnancy need to be balanced against potential teratogenic effects of antiepileptic drugs (AEDs). This article aims to review the literature on gestational effects on the pharmacokinetics of older and newer generation AEDs and discuss the implications for the treatment of epilepsy in women during pregnancy. Pregnancy can affect the pharmacokinetics of AEDs at any level from absorption, distribution, metabolism, to elimination. The effect varies depending on the type of AED. The most pronounced decline in serum concentrations is seen for AEDs that are eliminated by glucuronidation (UGT), in particular lamotrigine where the effect may be profound. Serum concentrations of AEDs that are cleared mainly through the kidneys, for example, levetiracetam, can also decline significantly. Some AEDs, such as carbamazepine seem to be affected only marginally by pregnancy. Data on pharmacokinetics during pregnancy are lacking completely for some of the newer generation AEDs: pregabalin, lacosamide, retigabine, and eslicarbazepine acetate. Where data are available, the effects of pregnancy on serum concentrations seem to vary considerably individually and are thus difficult to predict. Although large-scale systematic studies of the clinical relevance of the pharmacokinetic alterations are lacking, prospective and retrospective case series have reported an association between declining serum concentrations and deterioration in seizures control. The usefulness of routine monitoring of AED serum concentrations in pregnancy and of dose adjustments based on falling levels, are discussed in this review. We suggest that monitoring could be important, in particular when women have been titrated to the lowest effective AED

    Two antineoplastic agents, Imatinib (IM) and 5-Fluorouracil (FU) were conjugated by hydrolysable linkers through an amide bond and entrapped in polymeric Human Serum Albumin (HSA) nanoparticles. The presence of dual drugs in a common carrier has the advantage of reaching the site of action simultaneously and acting at different phases of the cell cycle to arrest the growth of cancer cells before they develop chemoresistance. The study has demonstrated an enhanced anticancer activity of the conjugate, and conjugate loaded stealth HSA nanoparticles (NPs) in comparison to the free drug in A-549 human lung carcinoma cell line and Zebra fish embryos (Danio rerio). Hydrolysability of the conjugate has also been demonstrated with complete hydrolysis being observed after 12 h. In vivo pharmacodynamics study in terms of tumor volume and pharmacokinetics in mice for conjugate (IM-SC-FU) and conjugate loaded nanoparticles showed significant anti-cancer activity. The other parameters evaluated were particle size (86nm), Poly Dispersive Index (PDI) (0.209), zeta potential (-49mV), drug entrapment efficiency (96.73%) and drug loading efficiency (89%). Being in stealth mode gives the potential for the NPs to evade Reticulo-Endothelial system (RES), achieve passive targeting by Enhanced Permeation Retention (EPR) effect with controlled release of the therapeutic agent. As the conjugate cleaves into individual drugs in the tumor environment, this promises better suppression of cancer chemoresistance by delivering dual drugs with different modes of action at the same site, thereby synergistically inhibiting the growth of cancerous tissue.

    2015-03-01

    Full Text Available Introduction: During the last few years there has been a considerable value growth in the demand for the so-called over-the-counter drugs (OTC, available without doctor’s prescription. Using OTC drugs is related to self-treatment, aimed at mitigating first symptoms of a cold, flu, or various types of pain. The omnipresent advertisements for OTC drugs encourage and contribute to the elevated demand. Unfortunately, the marketing techniques used in advertisements fail to provide reliable and objective information to the viewers about specific products. Aim of the research: To determine the respondents’ opinions on using OTC drugs and to assess how advertisements influence the consumers’ needs. Material and methods : The study was conducted by means of a diagnostic survey using a questionnaire. For the purpose of the study, the authors prepared a survey questionnaire, which was used as a research tool. The study included 114 respondents, falling within an age bracket of 18–66 years. Results : The most frequently used OTC drugs were painkillers and medicines for cold and flu symptoms (68.33% of women and 59.09% of men. The drugs were usually bought in pharmacies and grocery/convenience stores. Conclusions: Taking OTC drugs is a widespread phenomenon, both in women and men. The obtained results clearly indicate that advertisements have a considerable impact upon target groups and contribute to increased consumption of OTC drugs.

The present work was carried out to investigate how surface modification using plasma treatment modifies the surface energy of micro-injection moulded microneedles and its influence on drug delivery. Microneedles of polyether ether ketone and polycarbonate and have been manufactured using micro-injection moulding and samples from each production batch have been subsequently subjected to a range of plasma treatment. These samples were coated with bovine serum albumin to study the protein adsorption on these treated polymer surfaces. Sample surfaces structures, before and after treatment, were studied using atomic force microscope and surface energies have been obtained using contact angle measurement and calculated using the Owens-Wendt theory. Adsorption performance of bovine serum albumin and release kinetics for each sample set was assessed using a Franz diffusion cell. Results indicate that plasma treatment significantly increases the surface energy and roughness of the microneedles resulting in better adsorption and release of BSA.

    Background & objectives: There has been a limited focus on prescription drug abuse among women in the country. Choice of psychoactive substance, reasons for initiation and co-occurring disorders have been found to be different among men and women. The current study was aimed at studying the profile of female patients seeking in-patient treatment for prescription drug use over a period of five years at a tertiary care drug dependence treatment centre in India. Methods: Case records of all female patients admitted with substance use disorder at a national level drug dependence treatment centre in north India across five years (between January 2008 and December 2012) were reviewed retrospectively to study their socio-demographic and clinical profile. The information was gathered using a semi-structured proforma and detailed case records. Abstinence, relapse and retention rates were calculated. Results: Over the five years, 31 female patients were admitted with prescription drug abuse. Of them, 12 (39%) used prescription opioids and 11 (36%) used prescription opioid along with benzodiazepines. Commonest prescription opioid was pentazocine used by 87 per cent of the women. Twenty two (71%) women were introduced to opioid by medical practitioners and commonest reason for introduction was pain (among 48%). Common co-occurring psychiatric diagnoses were depressive disorder (26%), cluster B traits/disorder (19%) and somatoform disorder (13%). Eight women did not complete treatment and left against medical advice. Thirteen women were advised maintenance treatment, and 70 per cent of them were retained for at least six months. Interpretation & conclusions: Our findings revealed a link between mental illness, pain and non-medical use of prescription opioids among women. Majority of these women received opioids as a legitimate prescription form physician. Therefore, these legitimate prescribers should be trained for pain management to facilitate proper treatment of pain and to

  13. Drug resistance following irradiation of RIF-1 tumors: Influence of the interval between irradiation and drug treatment

    International Nuclear Information System (INIS)

    RIF-1 tumors contain a small number of cells (1 to 100 per 10(6) cells) that are resistant to 5-fluorouracil, methotrexate, or adriamycin. The frequency of drug-resistant cells among individual untreated tumors is highly variable. Radiation, delivered in vivo at doses of 3 to 12 Gy, increases the frequency of methotrexate- and 5-fluorouracil-resistant cells, but not the frequency of adriamycin-resistant cells. The magnitude of induction of 5-fluorouracil and methotrexate resistance shows a complex dependence on the radiation dose and on the interval between irradiation and assessment of drug resistance. For a dose of 3 Gy, induced 5-fluorouracil and methotrexate resistance is seen only after an interval of 5 to 7 days, whereas for a dose of 12 Gy, high levels of induced resistance are observed 1 to 3 days after irradiation. The maximum absolute risk for induction of resistance is 4 per 10(4) cells per Gy for methotrexate, and 3 per 10(6) cells per Gy for 5-fluorouracil. These results indicate that tumor hypoxia may play a role in the increased levels of drug resistance seen after irradiation, and that both genetic and environmental factors may influence radiation-induction of drug resistance. These studies provide essential data for models of the development of tumor drug resistance, and imply that some of the drug resistance seen when chemotherapy follows radiotherapy may be caused by radiation-induced drug resistance

    2012-03-01

    Full Text Available Abstract Cambodia, confronted by the spread of drug misuse among young people, requested support from international agencies to develop a drug treatment programme in 2000. The initial plan developed by the United Nations Office on Drugs and Crime was to set up a number of conventional drug treatment centres in urban areas. During the planning phase, however, the project was redesigned as a community based outreach programme. Ten Community Counselling Teams have been formed and trained in pilot areas, and within the first year of operation 462 drug and alcohol users contacted. Comprising former drug users, family members affected by drug use and health care staff, they have drug scene credibility, local knowledge and connectivity, and a rudimentary level of medical competence. Crucially, they enjoy the support of village elders, who are involved in the planning and reporting stages. While the Community Counselling Teams with their basic training in addiction counselling are in no position as yet to either provide or refer clients to treatment, they can provide brief interventions, organise self help groups, and most importantly provide an alternative to law enforcement. By taking a development centred approach, with emphasis on community, empowerment and inclusion, it provides a constructive and inclusive alternative to medical approaches and the compulsory drug treatment centres. The paper is based on an evaluation involving interviews with a range of stakeholders and a review of project documents.

    Only a small fraction of drug users worldwide enter treatment each year. We evaluated the efficacy of a systemic family outreach intervention (SFOI) for young, untreated drug users, using a quasi-experimental design in which the experimental group (EG) received SFOI and the control group (CG) received traditional outreach work (OW). Both pre- and post-treatment, we administered the Addiction Severity Index-6 (ASI-6), the Family Environment Scale (FES), and tests of parental practices and risky behavior. Post-treatment, there was a fivefold improvement on the ASI-6 and a significant worsening on the conflict sub-scale of the FES in the EG as compared with the CG. SFOI was more efficacious than OW in reducing drug use in the drug user's home environment. The increased conflict in the EG might be explained by parents' increased awareness of abnormal behaviors and implementation of strategies to protect their children. PMID:22520275

Materials and Methods: This retrospective study was carried out in a referral university hospital, Isfahan, Iran. The medical records of all patients who were hospitalized in the Dermatology Department due to ACDRs were reviewed covering an 8-year period between December 2006 and August 2013. Results: A total number of 282 patients with the mean age of 29.48 ± 21.18 years were hospitalized in this time period, of which 61% were females. The most common clinical patterns regarding the final diagnosis were Stevens-Johnson syndrome (SJS (32%, exanthematous drug eruptions (24.5% and toxic epidermal necrolysis (TEN (11%. Anticonvulsants were the most frequently implicated drug group (51.8% followed by antibiotics (33.7% and analgesics and non-steroidal anti-inflammatory drugs (5.7%. The most common cause of drug administration was seizure (30% and then upper respiratory tract infections (12%. The frequency distribution of clinical types of reactions was different between age groups (P < 0.001. The severe types (SJS, TEN, drug rash with eosinophilia and systemic symptoms and overlap syndrome were more frequent in the patients aged ≤50 years old (55.2% compare to those aged ≤50 years (28% (P = 0.001. Conclusion: The main causative drugs of ACDRs were anticonvulsants and antibiotics. However, the sever types of reactions were more prevalent.

    Overuse of benzodiazepine drugs to treat anxiety, mood, and sleep disorders is a growing problem in clinical practice. GABAergic medications (benzodiazepine drugs in particular) have side effects, drug interactions, and the potential to create tolerance and dependence in users. GABA-enhancing dietary supplements have similar and unique risks. Natural, non-chemical, anxiolytic treatments exist and can be safely recommended to patients. Three such treatments have been the focus of study in the past 20 years: mindfulness, meditation, and yoga. Growing evidence exists that these treatments can be safely recommended to patients with anxiety. [Journal of Psychosocial Nursing and Mental Health Services, 54(8), 35-42.]. PMID:27479478

    Relationships with family and friends by 439 heroin addicts during the first 3 months of drug abuse treatment were examined in relation to behavioral improvements of clients. Family conflict and peer deviance were significant predictors of injection frequency and illegal activity during treatment, and reductions in family conflict were associated with lower drug use, injection frequency, and illegal activity during treatment. These results provide support for treatment emphasis on helping clients reduce conflict among family members, improve dysfunctional relationships with peers, and replace deviant friendships with others that encourage treatment participation and conformance to social norms.

    Full Text Available Abstract Background Blood pressure lowering drugs are usually evaluated in short term trials determining the absolute blood pressure reduction during trough and the duration of the antihypertensive effect after single or multiple dosing. A lack of persistence with treatment has however been shown to be linked to a worse cardiovascular prognosis. This review explores the blood pressure reduction and persistence with treatment of antihypertensive drugs and the cost consequences of poor persistence with pharmaceutical interventions in arterial hypertension. Methods We have searched the literature for data on blood pressure lowering effects of different antihypertensive drug classes and agents, on persistence with treatment, and on related costs. Persistence was measured as patients' medication possession rate. Results are presented in the form of a systematic review. Results Angiotensin II receptor blocker (ARBs have a competitive blood pressure lowering efficacy compared with ACE-inhibitors (ACEi and calcium channel blockers (CCBs, beta-blockers (BBs and diuretics. 8 studies describing the persistence with treatment were identified. Patients were more persistent on ARBs than on ACEi and CCBs, BBs and diuretics. Thus the product of blood pressure lowering and persistence was higher on ARBs than on any other drug class. Although the price per tablet of more recently developed drugs (ACEi, ARBs is higher than that of older ones (diuretics and BBs, the newer drugs result in a more favourable cost to effect ratio when direct drug costs and indirect costs are also considered. Conclusion To evaluate drugs for the treatment of hypertension several key variables including the blood pressure lowering effect, side effects, compliance/persistence with treatment, as well as drug costs and direct and indirect costs of medical care have to be considered. ARBs, while nominally more expensive when drug costs are considered only, provide substantial cost savings

    Psoriasis is a chronic inflammatory skin disorder that may drastically impair the quality of life of a patient. Among the various modes of treatments for psoriasis, topical therapy is most commonly used in majority of patients. The topical formulations based on conventional excipients could serve the purpose only to a limited extent. With the advent of newer biocompatible and biodegradable materials like phospholipids, and cutting-edge drug delivery technologies like liposomes, solid lipid nanoparticles (SLNs), microemulsions, and nanoemulsions, the possibility to improve the efficacy and safety of the topical products has increased manifold. Improved understanding of the dermal delivery aspects and that of designing and developing diverse carrier systems have brought in further novelty in this approach. Substantial efforts and the consequent publications, patents and product development studies on the subject are the matter of interest and review of this article. However, majority of the work is related to the preclinical studies and demands further clinical assessment in psoriasis patients. PMID:21079304

  6. Stories of change in drug treatment: a narrative analysis of 'whats' and 'hows' in institutional storytelling.

    2015-06-01

    Addiction research has demonstrated how recovering individuals need narratives that make sense of past drug use and enable constructions of future, non-addict identities. However, there has not been much investigation into how these recovery narratives actually develop moment-to-moment in drug treatment. Building on the sociology of storytelling and ethnographic fieldwork conducted at two drug treatment institutions for young people in Denmark, this article argues that studying stories in the context of their telling brings forth novel insights. Through a narrative analysis of both 'the whats' (story content) and 'the hows' (storying process) the article presents four findings: (1) stories of change function locally as an institutional requirement; (2) professional drug treatment providers edit young people's storytelling through different techniques; (3) the narrative environment of the drug treatment institution shapes how particular stories make sense of the past, present and future; and (4) storytelling in drug treatment is an interactive achievement. A fine-grained analysis illuminates in particular how some stories on gender and drug use are silenced, while others are encouraged. The demonstration of how local narrative environments shape stories contributes to the general understanding of interactive storytelling in encounters between professionals and clients in treatment settings.

  7. Nanoparticles and drug eluting stents for disease detection and treatment

    Meng, Juan

    This thesis presents the results of experimental and theoretical studies of nanoparticle entry/adhesion to breast cancer cells and adhesion in drug-eluting stents. Atomic Force Microscopy (AFM) techniques are used to quantify the adhesion. The thermodynamics and kinetics concepts are presented for the modeling of nanoparticle entry into breast cancer cells. In the case of the drug-eluting stents studies, a combination of adhesion theory and fracture mechanics concepts is used to estimate the adhesion energies. To investigate the specific accumulation of the functionalized super-paramagnetic iron oxide nanoparticles (SPIONs) in breast cancer cells, a combination of transmission electron microscopy (TEM) and spectrophotometric analysis was used. It is shown that SPIONs conjugated to luteinizing hormone releasing hormone (LHRH) (LHRH-SPIONs), can be used to specifically target breast cancer cells. They also act as contrast enhancement agents during the magnetic resonance imaging (MRI) of breast cancer xenografts. The adhesion between LHRH and breast cancer cells is an important factor for LHRH-SPIONs to target breast cancer cells. AFM techniques were used to quantify adhesion between LHRH peptides and their receptors on breast cancer cells. The adhesion force between LHRH-coated AFM tips and human breast cancer cells is shown to be about five times greater than that between LHRH-coated AFM tips and normal breast cells. This result also suggests that force microscopy can be used for the specific detection of breast cancer cells. Adhesion and fracture mechanics techniques were used to study the adhesion between the drug eluting layer and Parylene C layer coated onto a model drug-eluting stent. AFM force--displacement measurements were used to quantify the adhesion between the parylene C primer and the drug-eluting layer and the cohesion between the three constituents of the drug-eluting layer. Adhesion theories were then used to relate the measured forces to adhesion

    The efficacy and safety of etrolizumab, a humanized IgG1 mAb, were evaluated in patients with ulcerative colitis (UC) in a phase 2 study (EUCALYPTUS). The current study assessed the risk of therapeutic protein drug-drug interaction (TP-DDI) of etrolizumab on CYP3A activity in patients with UC. Literature review was performed to compare serum proinflammatory cytokine levels and pharmacokinetic (PK) parameters of CYP3A substrate drugs between patients with inflammatory bowel disease (IBD) and healthy subjects. Treatment effect of etrolizumab on CYP3A activity was evaluated by measuring colonic CYP3A4 mRNA expression and serum C-reactive protein (CRP) in EUCALYPTUS patients. Literature data suggested similar levels between IBD patients and healthy subjects for serum proinflammatory cytokines and PK parameters of CYP3A substrate drugs. Additionally, treatment with etrolizumab did not change colonic CYP3A4 mRNA expression or serum CRP levels in UC patients. In conclusion, our results indicate a low TP-DDI risk for etrolizumab in UC patients, particularly on medications metabolized by CYP3A. PMID:26412221

    Health Technology Assessment (HTA) is a multidisciplinary health political instrument that evaluates the consequences, mainly clinical and economical, of a health care technology; the HTA aim is to produce and spread information on scientific and technological innovation for health political decision making process. Drug delivery systems (DDS), such as nanocarriers, are technologically complex but they have pivotal relevance in therapeutic innovation. The HTA process, as commonly applied to conventional drug evaluation, should upgrade to a full pharmaceutical assessment, considering the DDS complexity. This is useful to study more in depth the clinical outcome and to broaden its critical assessment toward pharmaceutical issues affecting the patient and not measured by the current clinical evidence approach. We draw out the expertise necessary to perform the pharmaceutical assessment and we propose a format to evaluate the DDS technological topics such as formulation and mechanism of action, physicochemical characteristics, manufacturing process. We integrated the above-mentioned three points in the Evidence Based Medicine approach, which is data source for any HTA process. In this regard, the introduction of a Pharmaceutics Expert figure in the HTA could be fundamental to grant a more detailed evaluation of medicine product characteristics and performances and to help optimizing DDS features to overcome R&D drawbacks. Some aspects of product development, such as manufacturing processes, should be part of the HTA as innovative manufacturing processes allow new products to reach more effectively patient bedside. HTA so upgraded may encourage resource allocating payers to invest in innovative technologies and providers to focus on innovative material properties and manufacturing processes, thus contributing to bring more medicines in therapy in a sustainable manner.

  19. The influence of radiation treatment on drugs and drug additives. Pt. 2

    International Nuclear Information System (INIS)

    The results obtained by experimental irradiation of 113 drugs and drug-additives (84 different drugs and drug-additives, 19 of which were examined by 2 authors, 2 by 4 authors and 1 by 5 authors) are reported and discussed. The substances were irradiated in pure form, as aqueous solutions with and without protective additives and separately from the solvent (preparation of the solution using separately irradiated components); they were irradiated almost exclusively by γ-radiation (Co-60) at doses between 0.05 and 100 Mrad or Mr. For radiation sterilization purposes the relevant dose range lies between 1 and 6 Mrad, where the results reveal the following characteristics: 1) In about 70% of the experiments, irradiation of solid substances showed no decomposition of the drugs or drug-additives, the greater part of the rest being decomposed only to a small extent. 2) In aqueous solutions irradiation caused, with rare exceptions, a more or less strong radiolysis in all solved pharmaceutical substances; it increased with decreasing concentrations of the solution and also with increasing dose levels. 3) Addition of sodium pyrosulphite to the solutions did not always have a stabilizing effect on the drug. 4) In the solutions consisting of separately irradiated components, a decomposition could be proved only if the irradiated solid substances already contained radiolysis products. 5) After irradiation of 52 substances (which were irradiated both as solid substances and as aqueous solution), 34 of them were not decomposed when being irradiated as solid substances; irradiation of these substances as aqueous solutions at the same dose levels, however, caused a more or less strong decomposition. 6) As to the relationship between decomposition and dose rate the results are inconsistent. 7) For 21 substances the results of heating and irradiation procedures for sterilization purposes were compared.

    Full Text Available Objectives: To analyze the prescribing pattern and appropriateness of drug treatment of diarrhoea in hospitalized children. The economic burden of the disease and adverse drug reactions (ADRs occurring during the course of treatment was also studied. Materials and Methods: It was a prospective, observational, single center study undertaken in pediatric inpatients of diarrhea, aged one month to twelve years over a period of eighteen months at a tertiary care teaching hospital in western India. Modified Kunin's criteria along with the guidelines set by the Indian Academy of Pediatrics (IAP and WHO were followed for assessing the appropriateness of the antimicrobials prescribed. The adverse drug reactions occurring during course of the treatment were noted and the economic burden of the disease was calculated as direct and indirect costs. Results: A total of 103 patients were enrolled, of whom 45% were in the age group of one month to one year. Diarrhoea with some dehydration was diagnosed in 50.5% patients followed by severe dehydration (34.9% and no dehydration (14.6%. The number of drugs and antimicrobials prescribed per patient were 7.53±1.87 and 1.92±0.67, respectively. Rehydration fluids (31.6% and antimicrobials (25.5% were the commonest drug groups prescribed. Among the antimicrobials, cefotaxime, cotrimoxazole and amoxicillin with clavulanic acid were frequently prescribed. Appropriate antibacterial therapy was given in only 13% of the cases. Only one ADR due to cotrimoxazole was observed. The economic burden of the disease was calculated to be Rs. 3164.81 per patient. Conclusion: Inappropriate use of antimicrobials was seen in the study. Emphasis on proper diagnosis and treatment, education and availability of locally effective guidelines may help in a better and judicious use of drugs in children.

    2014-01-01

    Background Young adulthood (ages 18–25 years) represents a time when high-risk behaviors, including alcohol and drug use, peak. Electronic music dance events (EMDEs) featured at clubs provide an ecologic niche for these high-risk behaviors. Purpose This paper examines the prevalence of alcohol and drug use among EMDE patrons. Examination of personal characteristics associated with exit levels of alcohol and drug use identifies important indicators of risk taking for prevention strategies. Methods Data were collected anonymously during 2010–2012 from 2028 patrons as they entered and exited clubs in the San Francisco Bay area featuring EMDEs. Nearly half were aged ≤25 years. Biological measures of drug and alcohol and self-reported personal characteristics were attained. Analyses were completed in 2012. Results At entrance, more than one fifth of patrons were positive for drug use and one fourth arrived either impaired (blood alcohol concentration [BAC]: 0.05%–0.079%) or intoxicated (BAC: >0.08%) by alcohol. At exit, one fourth tested positive for drugs, and nearly half were impaired or intoxicated by alcohol. Individual characteristics that were important for levels of risk included prior alcohol use behaviors, sexual identity, ethnic/racial identity, and transportation to the event. Gender did not differentiate for alcohol use but fewer women used drugs. Conclusions Findings confirm the importance of targeting EMDEs for prevention efforts. EMDEs attract young working adults who are engaged in heavy alcohol and/or drug use. Targeting these social settings for delivering public health prevention strategies regarding alcohol and drug use and related harms is indicated by the findings. PMID:24139778

    2013-01-01

    Background The Médecins Sans Frontières project of Uzbekistan has provided multidrug-resistant tuberculosis treatment in the Karakalpakstan region since 2003. Rates of default from treatment have been high, despite psychosocial support, increasing particularly since programme scale-up in 2007. We aimed to determine factors associated with default in multi- and extensively drug-resistant tuberculosis patients who started treatment between 2003 and 2008 and thus had finished approximately 2 years of treatment by the end of 2010. Methods A retrospective cohort analysis of multi- and extensively drug-resistant tuberculosis patients enrolled in treatment between 2003 and 2008 compared baseline demographic characteristics and possible risk factors for default. Default was defined as missing ≥60 consecutive days of treatment (all drugs). Data were routinely collected during treatment and entered in a database. Potential risk factors for default were assessed in univariate analysis using chi-square test and in multivariate analysis with logistic regression. Results 20% (142/710) of patients defaulted after a median of 6 months treatment (IQR 2.6–9.9). Factors associated with default included severity of resistance patterns (pre-extensively drug-resistant/extensively drug-resistant tuberculosis adjusted odds ratio 0.52, 95%CI: 0.31–0.86), previous default (2.38, 1.09–5.24) and age >45 years (1.77, 1.10–2.87). The default rate was 14% (42/294) for patients enrolled 2003–2006 and 24% (100/416) for 2007–2008 enrolments (p = 0.001). Conclusions Default from treatment was high and increased with programme scale-up. It is essential to ensure scale-up of treatment is accompanied with scale-up of staff and patient support. A successful first course of tuberculosis treatment is important; patients who had previously defaulted were at increased risk of default and death. The protective effect of severe resistance profiles suggests that understanding disease

    2016-09-01

    Chronic osteomyelitis (COM) is an infectious disease caused by methicillin-resistant Staphylococcus aureus (MRSA), the main characteristics of COM including local dead bone formation, soft tissue infection, and repeatedly attacks. As a sensitive antibiotic, vancomycin plays an important role in the therapy of COM caused by MRSA. Currently, drug treatment is divided into systemic and topical, systemic medication is given priority to intravenous drug delivery; local drug application including local delivery device and local antibiotics lavage and regional arterial perfusion. In practice, its validity depends on whether free drug concentration of vancomycin has riched the effective concentration in the organization. Nevertheless, low concentration lead to treatment failure and even induce drug-resistance bacteria, meanwhile high concentration may cause acute renal failure. So when using vancomycin for the treatment of chronic osteomyelitis, both drug resistance and renal toxicity is as the same important as the effectiveness. Systemic administration is a targeting weak way and has many complications; topical medicate effect on the lesion can be targeted, it would be an effective way in the future treatment of COM. Different methods of delivering vancomycin have great influence on local drug concentration, which makes it become the most important factor on local drug concentration of COM. PMID:27587217

    Tension-type headache (TTH) is a common primary headache with tremendous socioeconomic impact. Establishment of an accurate diagnosis is important before initiation of any treatment. Nondrug management is crucial. Information, reassurance and identification of trigger factors may be rewarding....... Psychological treatments with scientific evidence for efficacy include relaxation training, EMG biofeedback and cognitive-behavioural therapy. Physical therapy and acupuncture are widely used, but the scientific evidence for efficacy is sparse. Simple analgesics are the mainstays for treatment of episodic TTH...... efficacy and fewer side effects is urgently needed.

    2015-04-01

    Full Text Available AIMS - This article describes and analyses prisoners’ experiences of drug treatment in prison in four Nordic countries: Denmark, Finland, Norway and Sweden. The article examines how prisoners experience drug treatment, control and sanctions as related to three main topics, namely motivation; the content of the measure and relations to staff; and control and sanctions. METHODS & DATA - The article is based on data from twelve prisons, three in each of the four countries; 91 interviews with prisoners; and around six months of observation. The two main kinds of drug treatment measures are drug treatment units and day programmes. RESULTS - Prisoners described several motives to participate in drug treatment measures: to leave drugs and crime; to renew relations with family and friends; to solve health problems; and to improve their prison conditions. Prisoners found that drug treatment measures offered possibilities to acquire new ways of being. Staff behaviour seemed to be more important to prisoners than the methods used, and some prisoners seemed more positive to staff involved with the drug treatment than to other staff. A surprising finding was the prisoners’ limited critique of controls and sanctions. We see this as embedded in the situation of being a prisoner, and also in relation to contexts outside prison. CONCLUSION - In discussing their experiences in the treatment units, prisoners are not so concerned about the rehabilitative features or the controls and sanctions. They evaluate their present situation in light of a future, which is their real concern. This is in line with a main task for staff, which is to prepare prisoners for release.

  5. Altered network communication following a neuroprotective drug treatment.

    Directory of Open Access Journals (Sweden)

    Kathleen Vincent

    Full Text Available Preconditioning is defined as a range of stimuli that allow cells to withstand subsequent anaerobic and other deleterious conditions. While cell protection under preconditioning is well established, this paper investigates the influence of neuroprotective preconditioning drugs, 4-aminopyridine and bicuculline (4-AP/bic, on synaptic communication across a broad network of in vitro rat cortical neurons. Using a permutation test, we evaluated cross-correlations of extracellular spiking activity across all pairs of recording electrodes on a 64-channel multielectrode array. The resulting functional connectivity maps were analyzed in terms of their graph-theoretic properties. A small-world effect was found, characterized by a functional network with high clustering coefficient and short average path length. Twenty-four hours after exposure to 4-AP/bic, small-world properties were comparable to control cultures that were not treated with the drug. Four hours following drug washout, however, the density of functional connections increased, while path length decreased and clustering coefficient increased. These alterations in functional connectivity were maintained at four days post-washout, suggesting that 4-AP/bic preconditioning leads to long-term effects on functional networks of cortical neurons. Because of their influence on communication efficiency in neuronal networks, alterations in small-world properties hold implications for information processing in brain systems. The observed relationship between density, path length, and clustering coefficient is captured by a phenomenological model where connections are added randomly within a spatially-embedded network. Taken together, results provide information regarding functional consequences of drug therapies that are overlooked in traditional viability studies and present the first investigation of functional networks under neuroprotective preconditioning.

For the first time in nearly 50 years, there have been two new drugs registered for use in multidrug-resistant TB (MDR-TB. Bedaquiline, a diarylquinoline, and delamanid, a nitromidoxazole, have received conditional stringent regulatory approval and have World Health Organization interim policy guidance for their use. As countries improve and scale up their diagnostic services, increasing number of patients with MDR-TB and extensively drug-resistant TB are identified. These two new drugs offer a real opportunity to improve the outcomes of these patients. This article reviews the evidence for these two new drugs and discusses the clinical questions raised as they are used outside clinical trial settings. It also reviews the importance of the accompanying drugs used with these new drugs. It is important that barriers hindering the use of these two new drugs are addressed and that the existing clinical experience in using these drugs is shared, such that their routine-use programmatic conditions is scaled up, ensuring maximum benefit for patients and countries battling the MDR-TB crisis.

    The treatment of atopic dermatitis (AD) has long been viewed as a problematic issue by the medical profession. Although a wide variety of complementary therapies have been introduced, they fail to combine the skin moisturizing and drug supply for AD patients. This study reports the development of a thermo-sensitive Poloxamer 407/Carboxymethyl cellulose sodium (P407/CMCs) composite hydrogel formulation with twin functions of moisture and drug supply for AD treatment. It was found that the presence of CMCs can appreciably improve the physical properties of P407 hydrogel, which makes it more suitable for tailored drug loading. The fabricated P407/CMCs composite hydrogel was also characterized in terms of surface morphology by field emission scanning electron microscopy (FE-SEM), rheological properties by a rheometer, release profile in vitro by dialysis method and cytotoxicity test. More importantly, the findings from transdermal drug delivery behavior revealed that P407/CMCs showed desirable percutaneous performance. Additionally, analysis of cytotoxicity test suggested that P407/CMCs composite hydrogel is a high-security therapy for clinical trials and thus exhibits a promising way to treat AD with skin moisturizing and medication.

    Migraine is a common neurological syndrome that affects approximately 10-20% of the population. The pathophysiology of migraine is unclear. 5-hydroxytriptamine is a key mediator in the pathogenesis of migraine and thus 5-HT1-receptor agonists are the principal drugs for acute migraine therapy. There are three classes of drugs for migraine: over-the-counter analgesics and nonsteroidal anti-inflammatory drugs for acute mild migraine, specific prescription drugs (triptans and ergot alkaloids) for acute severe migraine and pharmacological agents for prophylaxis of migraine. Sumatriptan, naratriptan and others, referred to as 'triptans', are the mainstay for acute treatment of migraine. Ergot alkaloids (ergotamine, dihydroergotamine) are used in patients with frequent, moderate migraine, but are less effective than triptans. There are several agents for prevention of migraine occurrence in patients with frequent or severe disabling migraine attacks. New drugs with improved efficacy and reduced side effects are needed for effective treatment and prevention of migraine. PMID:23656340

  14. Impact of biomarker development on drug safety assessment

    International Nuclear Information System (INIS)

    Drug safety has always been a key aspect of drug development. Recently, the Vioxx case and several cases of serious adverse events being linked to high-profile products have increased the importance of drug safety, especially in the eyes of drug development companies and global regulatory agencies. Safety biomarkers are increasingly being seen as helping to provide the clarity, predictability, and certainty needed to gain confidence in decision making: early-stage projects can be stopped quicker, late-stage projects become less risky. Public and private organizations are investing heavily in terms of time, money and manpower on safety biomarker development. An illustrative and 'door opening' safety biomarker success story is the recent recognition of kidney safety biomarkers for pre-clinical and limited translational contexts by FDA and EMEA. This milestone achieved for kidney biomarkers and the 'know how' acquired is being transferred to other organ toxicities, namely liver, heart, vascular system. New technologies and molecular-based approaches, i.e., molecular pathology as a complement to the classical toolbox, allow promising discoveries in the safety biomarker field. This review will focus on the utility and use of safety biomarkers all along drug development, highlighting the present gaps and opportunities identified in organ toxicity monitoring. A last part will be dedicated to safety biomarker development in general, from identification to diagnostic tests, using the kidney safety biomarkers success as an illustrative example.

  16. Gametocytogenesis Following Drug Treatment of Plasmodium Falciparum in an Area of Seasonal Transmission in Sudan

    International Nuclear Information System (INIS)

    We monitored post-treatment Plasmodium falciparum among patients treated with chloroquine (CQ) and pyrimethamine-sulfadoxine (PS) in a village in eastern Sudan. Parasites were examined on day zero (pre-treatment), day 7, day 14 and day 21 (post-treatment) during the transmission season. A further sample was taken two months later (Day 80) at the start of the dry season. Asexual forms and gametocytes were detected by microscopy and reverse transcriptase polymerase chain reaction (RT-PCR) to detect expression of a gametocyte-specific protein pfg377. Gametocyte carriage, as revealed by microscopy, increased significantly following CQ and PS treatment reaching a maximum between days 7 and 14. When measured by RT-PCR, however, there was no significant difference in gametocyte rate between day 0 and day 7 or 14. RT-PCR gametocyte rates dropped dramatically by day 80 post-treatment but were still 33% and 8% in the CQ and PS treated group at this time. Alleles associated with drug resistance of P. falciparum to chloroquine (the chloroquine resistance transporter, pfcrt, and multi-drug resistance, pfmdr-1) and pyrimethamine (dihydrofolate reductase, dhfr) were at high frequency at the beginning of treatment and increased further through time under both drug treatments. Infections with drug-resistant parasites tended to have higher gametocyte prevalence than drug-sensitive infections.

    Malav Suchin Trivedi

    2015-01-01

    Full Text Available Alcohol and other drugs of abuse, including psychostimulants and opioids, can induce epigenetic changes: a contributing factor for drug addiction, tolerance and associated withdrawal symptoms. DNA methylation is the major epigenetic mechanism and it is one of more than 200 methylation reactions supported by methyl donor S-adenosylmethionine (SAM. The levels of SAM are controlled by cellular redox status via the folate and vitamin B12-dependent enzyme methionine synthase (MS, for example; under oxidative conditions MS is inhibited, diverting its substrate homocysteine (HCY to the transsulfuration pathway. Alcohol, dopamine and morphine, can alter intracellular levels of glutathione (GSH-based cellular redox status, subsequently affecting S-adenosylmethionine (SAM levels and DNA methylation status. In this discussion, we compile this and other existing evidence in a coherent manner to present a novel hypothesis implicating the involvement of redox-based epigenetic changes in drug addiction. Next, we also discuss how gene priming phenomenon can contribute to maintenance of redox and methylation status homeostasis under various stimuli including drugs of abuse. Lastly, based on our hypothesis and some preliminary evidence, we discuss a mechanistic explanation for use of metabolic interventions / redox-replenishers as symptomatic treatment of alcohol addiction and associated withdrawal symptoms. Hence, the current review article strengthens the hypothesis that neuronal metabolism has a critical bidirectional coupling with epigenetic changes in drug addiction and we support this claim via exemplifying the link between redox-based metabolic changes and resultant epigenetic consequences under the effect of drugs of abuse.

    2010-10-01

    Full Text Available Synergistic and antagonistic drug interactions are important to consider when developing mixtures of anticancer or other types of drugs. Boik, Newman, and Boik (2008 proposed the MixLow method as an alternative to the Median-Effect method of Chou and Talalay (1984 for estimating drug interaction indices. One advantage of the MixLow method is that the nonlinear mixed-effects model used to estimate parameters of concentration-response curves can provide more accurate parameter estimates than the log linearization and least-squares analysis used in the Median-Effect method. This paper introduces the mixlow package in R, an implementation of the MixLow method. Results are reported for a small simulation study.

    This article suggests that successful innovation in biopharmaceuticals is strongly related to the ability of firms to move compounds forward along the drug pipeline, relatively to other companies, within the same therapeutic area. We used this intuition to build indicators of performance at the firm-level and use them to conduct empirical analysis that relies upon a comprehensive database. We consider the effect of various factors on drug development performance, including R&D funds allocation across therapeutic areas and the proportion of biological molecules in the drug development portfolio. Subsequently, we show that a correlation exists between our performance variables and the per-capita growth of biopharmaceutical firms' revenues. PMID:23337387

  3. Perinatal Generalized Anxiety Disorder: Assessment and Treatment.

    Science.gov (United States)

    2015-09-01

    Perinatal generalized anxiety disorder (GAD) has a high prevalence of 8.5%-10.5% during pregnancy and 4.4%-10.8% postpartum. Despite its attendant dysfunction in the patient, this potentially debilitating mental health condition is often underdiagnosed. This overview will provide guidance for clinicians in making timely diagnosis and managing symptoms appropriately. A significant barrier to the diagnosis of GAD in the perinatal population is difficulty in distinguishing normal versus pathological worry. Because a perinatal-specific screening tool for GAD is nonexistent, early identification, diagnosis and treatment is often compromised. The resultant maternal dysfunction can potentially impact mother-infant bonding and influence neurodevelopmental outcomes in the children. Comorbid occurrence of GAD and major depressive disorder changes the illness course and its treatment outcome. Psychoeducation is a key component in overcoming denial/stigma and facilitating successful intervention. Treatment strategies are contingent upon illness severity. Cognitive behavior therapy (CBT), relaxation, and mindfulness therapy are indicated for mild GAD. Moderate/severe illness requires pharmacotherapy and CBT, individually or in combination. No psychotropic medications are approved by the FDA or Health Canada in pregnancy or the postpartum; off-label pharmacological treatment is instituted only if the benefit of therapy outweighs its risk. SSRIs/SNRIs are the first-line treatment for anxiety disorders due to data supporting their efficacy and overall favorable side effect profile. Benzodiazepines are an option for short-term treatment. While research on atypical antipsychotics is evolving, some can be considered for severe manifestations where the response to antidepressants or benzodiazepines has been insufficient. A case example will illustrate the onset, clinical course, and treatment strategies of GAD through pregnancy and the postpartum. PMID:26125602

    Full Text Available Abstract Background In spite of the disproportionate prevalence of hepatitis C virus (HCV infection among drug users, many remain uninformed or misinformed about the virus. Drug treatment programs are important sites of opportunity for providing HCV education to their patients, and many programs do, in fact, offer this education in a variety of formats. Little is known, however, about the level of HCV knowledge among drug treatment program patients, and the extent to which they utilize their programs' HCV education services. Methods Using data collected from patients (N = 280 in 14 U.S. drug treatment programs, we compared patients who reported that they never injected drugs (NIDUs with past or current drug injectors (IDUs concerning their knowledge about HCV, whether they used HCV education opportunities at their programs, and the facilitators and barriers to doing so. All of the programs were participating in a research project that was developing, implementing, and evaluating a staff training to provide HCV support to patients. Results Although IDUs scored higher on an HCV knowledge assessment than NIDUs, there were many gaps in HCV knowledge among both groups of patients. To address these knowledge gaps, all of the programs offered at least one form of HCV education: all offered 1:1 sessions with staff, 12 of the programs offered HCV education in a group format, and 11 of the programs offered this education through pamphlets/books. Only 60% of all of the participating patients used any of their programs' HCV education services, but those who did avail themselves of these HCV education opportunities generally assessed them positively. In all, many patients were unaware that HCV education was offered at their programs through individual sessions with staff, group meetings, and books/pamphlets, (42%, 49%, and 46% of the patients, respectively, and 22% were unaware that any HCV education opportunities existed.

    2014-05-01

    Full Text Available The synthesis method of layered double hydroxides (LDHs determines nanoparticles’ performance in biomedical applications. In this study, hydrothermal treatment as an important synthesis technique has been examined for its influence on the physicochemical properties and the drug release rate from drug-containing LDHs. We synthesised MgAl–LDHs intercalated with non-steroidal anti-inflammatory drugs (i.e., naproxen, diclofenac and ibuprofen using a co-precipitation method with or without hydrothermal treatment (150 °C, 4 h. After being hydrothermally treated, LDH–drug crystallites increased in particle size and crystallinity, but did not change in the interlayer anion orientation, gallery height and chemical composition. The drug release patterns of all studied LDH–drug hybrids were biphasic and sustained. LDHs loaded with diclofenac had a quicker drug release rate compared with those with naproxen and ibuprofen, and the drug release from the hydrothermally-treated LDH–drug was slower than the freshly precipitated LDH–drug. These results suggest that the drug release of LDH–drugs is influenced by the crystallite size of LDHs, which can be controlled by hydrothermal treatment, as well as by the drug molecular physicochemical properties.

    2004-02-01

    The assessment procedure of new synthetic illicit drugs that are not documented in the UN treaty on psychotropic drugs was evaluated using a modified Electre model. Drugs were evaluated by an expert panel via the open Delphi approach, where the written score was discussed on 16 items, covering medical, health, legal, and criminalistic issues of the drugs. After this face-to-face discussion the drugs were scored again. Taking the assessment of ketamine as an example, it appeared that each expert used its own scale to score, and that policymakers do not score deviant from experts trained in the medical-biological field. Of the five drugs evaluated by the panel, p-methoxy-metamphetamine (PMMA), gamma-hydroxybutyric acid (GHB), and 4-methylthio-amphetamine (MTA) were assessed as more adverse than ketamine and psilocine and psilocybine-containing mushrooms. Whereas some experts slightly adjusted during the assessment procedure their opinion on ketamine and PMMA, the opinion on mushrooms was not affected by the discussion held between the two scoring rounds. All experts rank the five drugs in a similar way on the adverse effect scale i.e., concordance scale of the Electre model, indicating unanimity in the expert panel with respect to the risk classification of these abused drugs.

    Nettleton, David O; Einolf, Heidi J

    2011-01-01

    Evaluation of the potential of a drug candidate to inhibit or inactivate cytochrome P450 (CYP) enzymes remains an important part of pharmaceutical drug Discovery and Development programs. CYP enzymes are considered to be one of the most important enzyme families involved in the metabolic clearance of the vast majority of prescribed drugs. Clinical drug-drug interactions (DDI) involving inhibition or time-dependent inactivation of these enzymes can result in dangerous side effects resulting from reduced clearance/increased exposure of the drug being affected (the 'victim' drug). In this regard, pharmaceutical companies have become quite vigilant in mitigating CYP inhibition/inactivation liabilities of drug candidates early in Discovery including continued risk assessment throughout Development. In this review, common strategies and decision making processes for the assessment of DDI risk in the different stages of pharmaceutical development are discussed. In addition, in vitro study designs, analysis, and interpretation of CYP inhibition and inactivation data are described in stage appropriate context. The in vitro tools and knowledge available now enable the Discovery Chemist to place the potential CYP DDI liability of a drug candidate into perspective and to aid in the optimization of chemical drug design to further mitigate this risk.

  20. Behaviour of pharmaceuticals and psychotic drugs in conventional and advanced wastewater treatments

    International Nuclear Information System (INIS)

    The occurrence of various pharmaceuticals and psychotic drugs in wastewater and their removal rates in a conventional wastewater treatment plant has been investigated. The psychoactive drugs are poorly removed in the biological step. However, most pharmaceuticals except of carbamazepine, are significantly biodegraded depending the removal degree on the type of compound and on the sludge retention time of the biological treatment. Also, the removal efficiency of conventional tertiary treatments and ultrafiltration and nano filtration membranes using two pilot plants was examined. the effects of retaining pharmaceuticals with ultrafiltration and nano filtration membranes do not greatly differ despite the difference in their pore size.

  3. Emerging drug -resistance and guidelines for treatment of malaria

    International Nuclear Information System (INIS)

    The increasing prevalence of multi-resistant Plasmodium falciparum malaria worldwide is a serious public health threat to the global control of malaria, especially in poor countries like Pakistan. In many countries chloroquine-resistance is a huge problem, accounting for more than 90% of malaria cases. In Pakistan, resistance to chloroquine is on the rise and reported in up to 16- 62% of Plasmodium falciparum. Four to 25% of Plasmodium falciparum also reported to be resistant to sulfadoxine-pyrimethamine and several cases of delayed parasite clearance have been observed in patients with Plasmodium falciparum malaria treated with quinine. In this article we have introduced the concept of artemisinin- based combination therapy (ACT) and emphasize the use of empiric combination therapy for all patients with Plasmodium falciparum malaria to prevent development of drug resistance and to obtain additive and synergistic killing of parasite.

    Neuromodulation is one of the most developing new disciplines of medical science, which examines how electrical, chemical and mechanical interventions can modulate or change the functioning of the central and peripheral nervous system. Neuromodulation is a reversible form of therapy which uses electrical or mechanical stimulation or centrally-delivered drugs to modulate the abnormal function of the central nervous system in pain, spasticity, epilepsy, movement and psychiatric disorders, and certain cardiac, incontinency, visual and auditory diseases. Neuromodulation therapy has two major branches. Non-invasive neuromodulation includes transcranial magnetic simulation, direct current stimulation and transcutaneous electric nerve stimulation. Invasive neuromodulation includes deep brain stimulation, cortical stimulation, spinal cord stimulation, peripheral nerve stimulation, sacral nerve simulation, and subcutan stimulation. In this article the authors overview the apparently available neural interface technologies in epilepsy surgery. PMID:26686746

    Full Text Available Methotrexate (MTX is a nonbiological disease-modifying antirheumatic drug that has shown both a good control of clinical disease and a good safety. Usually drug-drug interactions (DDIs represent the most limiting factor during the clinical management of any disease, in particular when several drugs are coadministered to treat the same disease. In this paper, we report the interactions among MTX and the other drugs commonly used in the management of rheumatoid arthritis. Using Medline, PubMed, Embase, Cochrane libraries, and Reference lists, we searched for the articles published until June 30, 2012, and we reported the most common DDIs between MTX and antirheumatic drugs. In particular, clinically relevant DDIs have been described during the treatment with MTX and NSAIDs, for example, diclofenac, indomethacin, or COX-2 inhibitors, and between MTX and prednisone or immunosuppressant drugs (e.g., leflunomide and cyclosporine. Finally, an increase in the risk of infections has been recorded during the combination treatment with MTX plus antitumor necrosis factor-α agents. In conclusion, during the treatment with MTX, DDIs play an important role in both the development of ADRs and therapeutic failure.

    2006-05-01

    Full Text Available BACKGROUND: Treatment of asymptomatic individuals, regardless of their malaria infection status, with regularly spaced therapeutic doses of antimalarial drugs has been proposed as a method for reducing malaria morbidity and mortality. This strategy, called intermittent preventive treatment (IPT, is currently employed for pregnant women and is being studied for infants (IPTi as well. As with any drug-based intervention strategy, it is important to understand how implementation may affect the spread of drug-resistant parasites. This is a difficult issue to address experimentally because of the limited size and duration of IPTi trials as well as the intractability of distinguishing the spread of resistance due to conventional treatment of malaria episodes versus that due to IPTi when the same drug is used in both contexts. METHODS AND FINDINGS: Using a mathematical model, we evaluated the possible impact of treating individuals with antimalarial drugs at regular intervals regardless of their infection status. We translated individual treatment strategies and drug pharmacokinetics into parasite population dynamic effects and show that immunity, treatment rate, drug decay kinetics, and presumptive treatment rate are important factors in the spread of drug-resistant parasites. Our model predicts that partially resistant parasites are more likely to spread in low-transmission areas, but fully resistant parasites are more likely to spread under conditions of high transmission, which is consistent with some epidemiological observations. We were also able to distinguish between spread of resistance due to treatment of symptomatic infections and that due to IPTi. We showed that IPTi could accelerate the spread of resistant parasites, but this effect was only likely to be significant in areas of low or unstable transmission. CONCLUSIONS: The results presented here demonstrate the importance of considering both the half-life of a drug and the existing level

    2011-06-01

    Full Text Available Abstract This article provides an overview of a sociological study of the views of 338 drug addiction treatment professionals. A comparison is drawn between the bioethical approaches of Russian and foreign experts from 18 countries. It is concluded that the bioethical priorities of Russian and foreign experts differ significantly. Differences involve attitudes toward confidentiality, informed consent, compulsory treatment, opioid agonist therapy, mandatory testing of students for psychoactive substances, the prevention of mental patients from having children, harm reduction programs (needle and syringe exchange, euthanasia, and abortion. It is proposed that the cardinal dissimilarity between models for providing drug treatment in the Russian Federation versus the majority of the countries of the world stems from differing bioethical attitudes among drug addiction treatment experts.

  12. Assessment and Treatment of Abuse Risk in Opioid Prescribing for Chronic Pain

    Directory of Open Access Journals (Sweden)

    Robert N. Jamison

    2011-01-01

    Full Text Available Opioid analgesics provide effective treatment for noncancer pain, but many physicians have concerns about adverse effects, tolerance, and addiction. Misuse of opioids is prominent in patients with chronic back pain and early recognition of misuse risk could help physicians offer adequate patient care while implementing appropriate levels of monitoring to reduce aberrant drug-related behaviors. In this review, we discuss opioid abuse and misuse issues that often arise in the treatment of patients with chronic back pain and present an overview of assessment and treatment strategies that can be effective in improving compliance with the use of prescription opioids for pain. Many persons with chronic back pain have significant medical, psychiatric and substance use comorbidities that affect treatment decisions and a comprehensive evaluation that includes a detailed history, physical, and mental health evaluation is essential. Although there is no “gold standard” for opioid misuse risk assessment, several validated measures have been shown to be useful. Controlled substance agreements, regular urine drug screens, and interventions such as motivational counseling have been shown to help improve patient compliance with opioids and to minimize aberrant drug-related behavior. Finally, we discuss the future of abuse-deterrent opioids and other potential strategies for back pain management.

  15. Pattern of illicit drug use in patients referred to addiction treatment centres in Birjand, Eastern Iran

    International Nuclear Information System (INIS)

    Objective: To evaluate the pattern of use of opioid and other illegal drugs in patients seeking addiction treatment in Birjand, eastern Iran. Methods: The prospective study was conducted from March 21, 2009 to March 21, 2010, and comprised all patients referred to the seven addiction treatment centres in Birjand. Data was obtained through pre-designed questionnaires and it was analysed using SPSS 16. Results: Of the 700 substance users referred to the 7 centres and who volunteered to participate, 632 (90.3%) were males and 68 (9.7%) were females. The male/female ratio was approx 9.3/1. Mean age was 34+-10.2 (range: 10-75) years. The type of drugs used included traditional drugs (n= 342; 48.9%) and newer modern drugs (n=314; 44.9 %). The mean age of the first experience with drugs was 21.91+-7.1 (range=0-60) years. There was significant different between the type of drugs used and the place of residence (p<0.019), age (p<0.0001), martial status (p<0.0001), occupation (p<0.006) and education (p<0.017). Conclusion: The prevalence of illicit drug addiction was quite high. There seemed to have been a change in the pattern of drug use and in the type of illegal drugs used in the study area, from traditional drugs to new and modern drugs. As such, identifying risk factors related to addiction and the prevention of addiction should be one of the most important health priorities for the authorities. (author)

  16. Anorexia nervosa: aetiology, assessment, and treatment.

    2015-12-01

    Anorexia nervosa is an important cause of physical and psychosocial morbidity. Recent years have brought advances in understanding of the underlying psychobiology that contributes to illness onset and maintenance. Genetic factors influence risk, psychosocial and interpersonal factors can trigger onset, and changes in neural networks can sustain the illness. Substantial advances in treatment, particularly for adolescent patients with anorexia nervosa, point to the benefits of specialised family-based interventions. Adults with anorexia nervosa too have a realistic chance of achieving recovery or at least substantial improvement, but no specific approach has shown clear superiority, suggesting a combination of re-nourishment and anorexia nervosa-specific psychotherapy is most effective. To successfully fight this enigmatic illness, we have to enhance understanding of the underlying biological and psychosocial mechanisms, improve strategies for prevention and early intervention, and better target our treatments through improved understanding of specific disease mechanisms.

Two groups of males (40 Ss between 18 and 60 years of age) and two groups of females (19 Ss between 18 and 55 years of age) with at least one year of abstinence were studied. The main issues considered were: reason for attending treatment or ceasing the use of substances, factors related to maintenance of abstinence, and difficulties and threats associated with abstinence. Several significant differences were found between groups with and without treatment, as well as between males and females, particularly regarding factors related to the maintenance of abstinence. In both cases family and affective links appear as the most relevant factors in the decision to stop using substances. On the other hand, commitment to one's goals and life project are the principal motives for maintaining abstinence or moderate consumption. This reflects the progressive transition from cognitive and emotional processes with external referents to processes with internal referents, associated with personal achievement. PMID:18173103

    The ejaculation distribution theory (EDT) postulates a biological continuum of the intravaginal ejaculation latency time (IELT) in men. Such an continuum has recently been found in two epidemiological stopwatch studies. In addition, a continuum of ejaculation latency time has also been demonstrated in laboratory rats. It is suggested that the invariable parts of ejaculation, i.e. premature and retarded ejaculation are highly influenced by genetic and neurobiological factors. In contrast, superimposed on biological roots, ejaculation of men, in the middle part of the continuum, is probably more easily influenced by environmental and psychological factors. A meta-analysis of 35 daily SSRI and clomipramine treatment studies demonstrated a similar efficacy for paroxetine, clomipramine, sertraline and fluoxetine, with paroxetine exerting the strongest effect on ejaculation. Based on fundamental insights into serotonergic neurotransmission, it is suggested that on-demand conventional SSRI treatment will not lead to similarly impressive ejaculation delay as that found after daily conventional SSRI treatment. Future studies with SSRIs with short half-lives, short T(max) and high C(max )should elucidate whether these pharmacokinetic properties are able to affect the pharmacodynamics of 5-HT neurons in such a way that immediate clinically relevant ejaculation delay occurs.

    While the overall percentage of unused antiretroviral medicines returned to the hospital pharmacy is low, their cost is quite high. Adverse events, treatment failure, pharmacokinetic interactions, pregnancy, or treatment simplification are common reasons for unplanned treatment changes. Socially inefficient antiretroviral packages prevent the reuse of drugs returned to the hospital pharmacy. We defined antiretroviral package categories based on the excellence of drug packaging and analyzed the number of pills and costs of drugs returned during a period of 1 year in a hospital-based HIV unit attending to 2,413 treated individuals. A total of 6,090 pills (34% of all returned antiretrovirals) - with a cost of 47,139.91 € - would be totally lost, mainly due to being packed up in the lowest efficiency packages. Newer treatments are packaged in low-excellence categories of packages, thus favoring the maintenance of these hidden costs in the near future. Therefore, costs of this low-efficiency drug packaging, where medication packages are started but not completed, in high-cost medications are substantial and should be properly addressed. Any improvement in the packaging by the manufacturer, and favoring the choice of drugs supplied through efficient packages (when efficacy, toxicity, and convenience are similar), should minimize the treatment expenditures paid by national health budgets.

    Inadequate dosing and incomplete treatment regimens, coupled with the ability of the tuberculosis bacilli to cause latent infections that are tolerant of currently used drugs, have fueled the rise of multidrug-resistant tuberculosis (MDR-TB). Treatment of MDR-TB infections is a major clinical challenge that has few viable or effective solutions; therefore patients face a poor prognosis and years of treatment. This review focuses on emerging drug classes that have the potential for treating MDR-TB and highlights their particular strengths as leads including their mode of action, in vivo efficacy, and key medicinal chemistry properties. Examples include the newly approved drugs bedaquiline and delaminid, and other agents in clinical and late preclinical development pipeline for the treatment of MDR-TB. Herein, we discuss the challenges to developing drugs to treat tuberculosis and how the field has adapted to these difficulties, with an emphasis on drug discovery approaches that might produce more effective agents and treatment regimens.

  7. No change of dopamine transporter density in basal ganglia after risperidone treatment in drug-naive children with Tourette's disorder

    International Nuclear Information System (INIS)

    Tourette's disorder (TD), which is characterized by multiple waxing and waning motor tics and one or more vocal tics, is known to be associated with abnormalities in the dopaminergic system. To testify our hypothesis that risperidone would improve tic symptoms of TD patients through the change of the dopaminergic system, we measured the DAT densities between drug-naive children with TD and normal children investigated the DAT density before and after treatment with risperidone in drug-naive children with TD, using lodine-123 labelled N-(3-iodopropen-2-yl)-2beta-carbomethoxy-3beta-(4-chlorophenyl) tropane(I-123 IPT) single photon emission computed tomography (SPECT). I-123 IPT SPECT imaging and Yale Global Tic Severity Scale-Korean version (YGTSS-K) for assessing the tic symptom severity were carried out before and after treatment with risperidone for 8 weeks in eight drug-naive children with TD. Eight normal children also underwent SPECT imaging 2 hours after an intravenous administration of I-123 IPT and carried out both quantitative and qualitative analyses using the obtained SPECT data, which were reconstructed for the assessment of the specific/non-specific DAT binding ratio in the basal ganglia. The drug-naive children with TD had a significantly greater increase in the specific/nonspecific DAT binding ratio of both basal ganglia compared with the normal children. However, no significant difference in the specific/nonspecific DAT binding ratio of the basal ganglia before and after treatment with riperidone in children with TD was not found, although tic symptoms were significantly improved with risperidone. These findings suggest that DAT densities are directly associated with the pathophysiology of TD, however, that the effect of risperidone on tic symptoms in children with TD is not attributed to the change of dopaminergic system

    The current treatment for drug-resistant tuberculosis (TB) is long, complex, and associated with severe and life-threatening side effects and poor outcomes. For the first time in nearly 50 years, there have been two new drugs registered for use in multidrug-resistant TB (MDR-TB). Bedaquiline, a diarylquinoline, and delamanid, a nitromidoxazole, have received conditional stringent regulatory approval and have World Health Organization interim policy guidance for their use. As countries improve and scale up their diagnostic services, increasing number of patients with MDR-TB and extensively drug-resistant TB are identified. These two new drugs offer a real opportunity to improve the outcomes of these patients. This article reviews the evidence for these two new drugs and discusses the clinical questions raised as they are used outside clinical trial settings. It also reviews the importance of the accompanying drugs used with these new drugs. It is important that barriers hindering the use of these two new drugs are addressed and that the existing clinical experience in using these drugs is shared, such that their routine-use programmatic conditions is scaled up, ensuring maximum benefit for patients and countries battling the MDR-TB crisis.

    2009-06-01

    A multisite, randomized trial within the National Drug Abuse Treatment Clinical Trials Network (CTN) was conducted to test 3 interventions to enhance treatment initiation following detoxification: (a) a single session, therapeutic alliance intervention (TA) added to usual treatment; (b) a 2-session, counseling and education, HIV/HCV risk reduction intervention (C&E), added to usual treatment; and (c) treatment as usual (TAU) only. Injection drug users (n=632) enrolled in residential detoxification at 8 community treatment programs were randomized to 1 of the 3 study conditions. TA participants reported entering outpatient treatment sooner and in greater numbers than TAU participants. Reported treatment entry for C&E fell between TA and TAU with no significant differences between C&E and the other conditions. There were no differences among the interventions in retention, as measured by weeks of outpatient treatment for all participants who reported treatment entry. Alliance building interventions appear to be effective in facilitating transfer from detoxification to outpatient treatment, but additional treatment engagement interventions may be necessary to improve retention.

    Chronic hepatitis C virus (HCV) is a global concern. With the 2014 Food and Drug Administration approvals of two direct-acting antiviral (DAA) regimens, ledipasvir/sofosbuvir regimen and the ombitasvir/paritaprevir/ritonavir and dasabuvir regimen, we may now be in the era of all-pill regimens for HCV. Until this development, interferon-alpha along with Ribavirin has remained part of the standard of care for HCV patients. That regimen necessitates psychosocial assessment of factors affecting treatment eligibility, including interferon-alpha-related depressive symptoms, confounding psychiatric conditions, and social aspects such as homelessness affecting treatment eligibility. These factors have delayed as much as 70% of otherwise eligible candidates from interferon-based treatment, and have required treating physicians to monitor psychiatric as well as medical side effects throughout treatment. All-pill DAA regimens with the efficaciousness that would preclude reliance upon interferon-alpha or ribavirin have been anticipated for years. Efficacy studies for these recently approved DAA regimens provide evidence to assess the degree that psychosocial assessment and monitoring will be required. With shorter treatment timelines, greatly reduced side effect profiles, and easier regimens, psychosocial contraindications are greatly reduced. However, current or recent psychiatric comorbidity, and drug-drug interactions with psychiatric drugs, will require some level of clinical attention. Evidence from these efficacy studies tentatively demonstrate that the era of needing significant psychosocial assessment and monitoring may be at an end, as long as a manageable handful of clinical issues are managed.

    Background Lymphatic filariasis (LF) is targeted for global elimination through treatment of entire at-risk populations with repeated annual mass drug administration (MDA). Essential for program success is defining and confirming the appropriate endpoint for MDA when transmission is presumed to have reached a level low enough that it cannot be sustained even in the absence of drug intervention. Guidelines advanced by WHO call for a transmission assessment survey (TAS) to determine if MDA can be stopped within an LF evaluation unit (EU) after at least five effective rounds of annual treatment. To test the value and practicality of these guidelines, a multicenter operational research trial was undertaken in 11 countries covering various geographic and epidemiological settings. Methodology The TAS was conducted twice in each EU with TAS-1 and TAS-2 approximately 24 months apart. Lot quality assurance sampling (LQAS) formed the basis of the TAS survey design but specific EU characteristics defined the survey site (school or community), eligible population (6–7 year olds or 1st–2nd graders), survey type (systematic or cluster-sampling), target sample size, and critical cutoff (a statistically powered threshold below which transmission is expected to be no longer sustainable). The primary diagnostic tools were the immunochromatographic (ICT) test for W. bancrofti EUs and the BmR1 test (Brugia Rapid or PanLF) for Brugia spp. EUs. Principal Findings/Conclusions In 10 of 11 EUs, the number of TAS-1 positive cases was below the critical cutoff, indicating that MDA could be stopped. The same results were found in the follow-up TAS-2, therefore, confirming the previous decision outcome. Sample sizes were highly sex and age-representative and closely matched the target value after factoring in estimates of non-participation. The TAS was determined to be a practical and effective evaluation tool for stopping MDA although its validity for longer-term post-MDA surveillance

    Full Text Available Tuberculosis is a familiar ailment in India and worldwide and is chief cause of mortality among all the infectious diseases. In present scenario therapy of Isoniazid, Rifampicin, Pyrazinamide and Ethambutol are commonly recommended against TB. These drugs lead to many adverse reactions which are one of the major reasons for non adherence of patients to these drugs that may lead to development of MDR. With the current scenario of MDR cases rising, this problem of adverse drug reactions cannot be taken lightly. Due to lack of successful drugs for treatment of toxicity caused by anti-TB drugs we have to turn towards traditional medicine. Ayurveda is an ancient system of natural and holistic medicine. Ayurvedic herbs have still being used as a part of treatment regimen in many parts of world. Local people still use these herbs as they are full of curative properties. Because anti-tubercular drugs induced toxicity leads to oxidative enzymes imbalance also leads to necrosis in liver tissue and many other degenerative changes, herbal extracts were experimented upon to test their ability to ameliorate toxicity by activating protective pathways. In this review we have summarized few of such herbs whose extracts were tested for their curative properties against anti-tubercular drugs induced toxicity.The main constituents in extracts that were responsible for protective effects have also been summarized along with their mechanisms of action.

    Tuberculosis (TB) is an infectious and transmissible disease that is caused by Mycobacterium tuberculosis and primarily affects the lungs, although it can affect other organs and systems. The pulmonary presentation of TB, in addition to being more frequent, is also the most relevant to public health because it is primarily responsible for the transmission of the disease. The to their low World Health Organization (WHO) recommends a combined therapeutic regimen of several drugs, such as rifampicin (RIF), isoniazid (INH), pyrazinamide (PZA) and ethambutol (ETB). These drugs have low plasma levels after oral administration, due to their low water solubility, poor permeability and ability to be rapidly metabolized by the liver and at high concentrations. Furthermore, they have short t₁/₂ (only 1-4 hours) indicating a short residence in the plasma and the need for multiple high doses, which can result in neurotoxicity and hepatotoxicity. Nanotechnology drug delivery systems have considerable potential for the treatment of TB. The systems can also be designed to allow for the sustained release of drugs from the matrix and drug delivery to a specific target. These properties of the systems enable the improvement of the bioavailability of drugs, can reduce the dosage and frequency of administration, and may solve the problem of non-adherence to prescribed therapy, which is a major obstacle to the control of TB. The purpose of this study was to systematically review nanotechnology-based drug delivery systems for the treatment of TB. PMID:27305759

    The inhibitory effect of boceprevir (BOC), an inhibitor of hepatitis C virus nonstructural protein 3 protease was evaluated in vitro against a panel of drug-metabolizing enzymes and transporters. BOC, a known substrate for cytochrome P450 (P450) CYP3A and aldo-ketoreductases, was a reversible time-dependent inhibitor (k(inact) = 0.12 minute(-1), K(I) = 6.1 µM) of CYP3A4/5 but not an inhibitor of other major P450s, nor of UDP-glucuronosyltransferases 1A1 and 2B7. BOC showed weak to no inhibition of breast cancer resistance protein (BCRP), P-glycoprotein (Pgp), or multidrug resistance protein 2. It was a moderate inhibitor of organic anion transporting polypeptide (OATP) 1B1 and 1B3, with an IC(50) of 18 and 4.9 µM, respectively. In human hepatocytes, BOC inhibited CYP3A-mediated metabolism of midazolam, OATP1B-mediated hepatic uptake of pitavastatin, and both the uptake and metabolism of atorvastatin. The inhibitory potency of BOC was lower than known inhibitors of CYP3A (ketoconazole), OATP1B (rifampin), or both (telaprevir). BOC was a substrate for Pgp and BCRP but not for OATP1B1, OATP1B3, OATP2B1, organic cation transporter, or sodium/taurocholate cotransporting peptide. Overall, our data suggest that BOC has the potential to cause pharmacokinetic interactions via inhibition of CYP3A and CYP3A/OATP1B interplay, with the interaction magnitude lower than those observed with known potent inhibitors. Conversely, pharmacokinetic interactions of BOC, either as a perpetrator or victim, via other major P450s and transporters tested are less likely to be of clinical significance. The results from clinical drug-drug interaction studies conducted thus far are generally supportive of these conclusions. PMID:23293300

    Full Text Available Vitiligo is a psychologically devastating condition. Topical therapy is employed as first-line treatment in localized vitiligo. Currently, several topical agents are available in many forms viz. methoxsalen (solution and cream, trioxsalen (solution, corticosteroids (gel, cream, ointment and solution and calcineurin inhibitors (ointment and cream. Although topical therapy has an important position in vitiligo treatment, side-effects or poor efficacy affect their utility and patient compliance. Novel drug delivery strategies can play a pivotal role in improving the topical delivery of various drugs by enhancing their epidermal localization with a concomitant reduction in their side-effects and improving their effectiveness. The current review emphasizes the potential of various phospholipid based carriers viz. liposomes, transferosomes, ethosomes, lipid emulsions, solid lipid nanoparticles and organogels in optimizing and enhancing the topical delivery of anti-vitiligo agents, whilst reducing the side effects of drugs commonly used in its topical treatment.

    2015-01-01

    Alzheimer's disease is a neurological disorder that results in cognitive and behavioral impairment. Conventional treatment strategies, such as acetylcholinesterase inhibitor drugs, often fail due to their poor solubility, lower bioavailability, and ineffective ability to cross the blood-brain barrier. Nanotechnological treatment methods, which involve the design, characterization, production, and application of nanoscale drug delivery systems, have been employed to optimize therapeutics. These nanotechnologies include polymeric nanoparticles, solid lipid nanoparticles, nanostructured lipid carriers, microemulsion, nanoemulsion, and liquid crystals. Each of these are promising tools for the delivery of therapeutic devices to the brain via various routes of administration, particularly the intranasal route. The objective of this study is to present a systematic review of nanotechnology-based drug delivery systems for the treatment of Alzheimer's disease. PMID:26345528

    Full Text Available Background: Population-based surveys demonstrate cannabis users are more likely to use both illicit and licit substances, compared with non-cannabis users. Few studies have examined the substance use profiles of cannabis users referred for treatment. Coexisting mental health symptoms and underlying cannabis-related beliefs associated with these profiles remains unexplored.Methods: Comprehensive drug use and dependence severity (Severity of Dependence Scale- Cannabis [SDS-C] data were collected on a sample of 826 cannabis users referred for treatment. Patients completed the General Health Questionnaire (GHQ-28, Cannabis Expectancy Questionnaire (CEQ, and Cannabis Refusal Self-Efficacy Questionnaire (CRSEQ and Positive Symptoms and Manic-Excitement subscales of the Brief Psychiatric Rating Scale (BPRS. Latent class analysis (LCA was performed on last month use of drugs to identify patterns of multiple drug use. Mental health comorbidity and cannabis beliefs were examined by identified drug use pattern.Results: A three-class solution provided the best fit to the data- (1 Cannabis and tobacco users (n = 176, (2 Cannabis, tobacco, and alcohol users (n = 498, and (3 wide-ranging substance users (n = 132. Wide-ranging substance users (3 reported higher levels of cannabis dependence severity, negative cannabis expectancies, lower opportunistic and emotional relief self-efficacy, higher levels of depression and anxiety, and higher manic-excitement and positive psychotic symptoms.Conclusion: In a sample of cannabis users referred for treatment, wide-ranging substance use was associated with elevated risk on measures of cannabis dependence, comorbid psychopathology and dysfunctional cannabis cognitions. These findings have implications for cognitive-behavioural assessment and treatment.

    Interventions that have been utilized to control seizures in people with epilepsy have been employed by the psychiatric community to treat a variety of disorders. The purpose of this review will be to give an overview of the most prominent uses of antiepileptic drugs (AEDs) and devices like the Vagus Nerve Stimulator (VNS) and Transcranial Magnetic Stimulation (TMS) in the treatment of psychiatric disease states. By far, the most prevalent use of these interventions is in the treatment of mood disorders. AEDs have become a mainstay in the effective treatment of Bipolar Affective Disorder (BAD). The U.S. Food and Drug Administration has approved the use of valproic acid for acute mania, and lamotrigine for BAD maintenance therapy. AEDs are also effectively employed in the treatment of anxiety and aggressive disorders. Finally, VNS and TMS are emerging as possibly useful tools in the treatment of more refractory depressive illness. PMID:15112459

    2007-10-01

    As a result of limited budgets, many treatment programs are forced to operate for extended periods at or beyond their capacity. The resulting pressure and stress on treatment staff can be taxing and lead to serious problems, including job burnout. Although the concept of burnout within other social service professions has been broadly researched, less attention has been given to burnout among drug abuse treatment staff, especially among corrections-based drug treatment staff. The goal of this article is to extend this area of research by exploring the impact of individual factors and organizational factors on burnout. Findings revealed that although a number of factors were related to staff burnout, younger counselor age, lower adaptability, poorer clarity of agency mission, and higher stress were most significant. Ways in which treatment programs might address these issues affecting staff burnout are discussed. PMID:17615435

    2014-07-01

    A majority of patients diagnosed with multiple sclerosis (MS) will develop lower urinary tract symptoms (LUTS) during the course of the disease. Even if antimuscarinic (anticholinergic) treatment is currently the mainstay of conservative treatment of neurogenic detrusor overactivity (NDO), including MS-induced NDO, extensive data regarding their effectiveness and safeness are lacking. When antimuscarinic medications fail to prove efficacious, a further option is intradetrusor injections of onabotulinumtoxin A. In several studies, more than half (and up 76%) of the patients treated with onabotulinumtoxin A experienced significant improvement in symptoms or even achieved complete continence. Cannabis extracts have shown some promise but has still not gained wide acceptance as an effective treatment. Over the last few years many new disease-modifying drugs that have been approved and introduced for treatment of MS. These drugs may have effects not only on the MS disease process, but also on the disease symptoms, including LUTS. However, MS is not primarily a bladder disease and treatment of the underlying pathophysiology should be the main goal of treatment. Since most of the urology drugs are targeting LUTS, these drugs should be regarded as "adds on" to treatments modifying the underlying disorder. Considering that most of these drugs have not been studied specifically with respect to efficacy on LUTS, and since they are not without significant side effects, it seems important that if and when they are going to be used for treatment of bladder symptoms should be a joint decision between the neurologist and urologist taking care of the patient.

    ), glutamate (e.g. topiramate), serotonin (e.g. ondansetron) or γ-aminobutyric acid (e.g. baclofen and topiramate) systems, may prove to show some benefit in certain forms of OCD. Based on the available evidence, we suggest that the treatment of patients with these disorders must account for alterations in the underlying motivations and neurobiology of the condition. We provide an initial guide to the specific treatments that future clinical trials might consider in patients with OCD. For example, it might be wise to test naltrexone in patients with co-morbid SUD and ICD, topiramate in patients with co-morbid ICD and eating disorders, and baclofen in patients with co-morbid Tourette's syndrome. These trials could also include scales aimed at assessing underlying impulsivity (e.g. Barratt Impulsiveness Scale) to check whether this construct might predict response to drugs acting on the reward system.

    2016-06-01

    The focus of the current study was to identity mental health, relationship factors, substance use related problems, and individual factors as predictors of couples-based substance abuse treatment initiation and attendance. Heterosexual couples with children that met study criteria were invited to attend 12 sessions of outpatient behavioral couples therapy. Men were more likely to initiate treatment if they had a higher income, had greater relationship satisfaction, were initiating treatment for alcohol use disorder only, were younger when they first suspected a problem, and had higher depression but lower hostility or phobic anxiety. Men attended more treatment sessions if they reported less intimate partner victimization, if they sought treatment for both alcohol and drug use disorder, if they were older when they first suspected a substance use problem, and if they were more obsessive-compulsive, more phobic anxious, less hostile, and experienced less somatization and less paranoid ideation. For women, treatment initiation was associated with less cohesion in their relationships, more somatization, and being older when they first suspected an alcohol or drug use problem. Trends were observed between women's treatment retention and being older, experiencing more somatization, and suspecting drug-related problems when they were younger; however, no predictors reached statistical significance for women. Results suggest that different factors may be associated with men and women's willingness to initiate and attend conjoint treatment for substance abuse. (PsycINFO Database Record PMID:27064819

    The evidence linking the personality trait of impulsivity and substance misuse is well established. Importantly, impulsivity not only predicts substance misuse problems but has an association with duration in treatment, likelihood of completing treatment and time to relapse. Treatment that focuses on increasing awareness and acceptance of thoughts and emotions may potentially address impulsive behaviour and in this respect improve treatment outcomes for substance misuse. The current paper investigated the relationship between the facet of impulsivity that taps into poor inhibitory control and treatment outcome. In addition, there was a specific focus on ascertaining the impact of an increase in awareness and attentional control measured in 144 adult substance users receiving treatment in a residential therapeutic community. Impulsivity predicted poorer treatment outcome (measured as drug use severity). Increases in awareness and acceptance of emotions and thoughts during treatment were related to better outcome although this was not associated with baseline levels of impulsivity. Clinical and theoretical implications are discussed. PMID:24924874

    The biomedical intervention that has had a major impact on the natural history of HIV and on the global HIV epidemic is antiretroviral therapy (ART). However, the emergence of drug-resistant HIV, an inevitable consequence of increasing use of antiretroviral drugs, poses a major threat to ART success. At the turn of this century, access to life-saving ART was accelerated in low and middle-income countries with the Millennium Development Goal of 15 million individuals receiving ART by 2015 expected to be achieved. However, ART access needs to continue to expand to help bring HIV under control by 2030. The standard of care for people living with HIV in resource- limited settings differs dramatically compared to high-income countries, and not unexpectedly, ART rollout in these settings has resulted in an increase in acquired and transmitted drug resistance. Also of concern, the same drug classes used for ART have been approved or are being progressed for HIV prevention and drug resistance could mitigate their effectiveness for treatment and prevention. In the absence of an effective HIV vaccine and cure, it is imperative that the antiretroviral drug pipeline contains new classes of HIV inhibitors that are active against circulating drug-resistant strains. Studies to advance our fundamental understanding of HIV replication needs to continue, including the interplay between virus and host cell factors, to identify and characterize new drug targets for chemotherapeutic intervention.

    Trauma involving the dentoalveolar region is a frequent occurrence which can result in the fracturing and displacement of teeth, crushing and/or fracturing of bone and soft tissue injuries including contusions, abrasions and lacerations. This review describes the assessment of patients with these injuries, not in a didactic sense by repeating excellent already published classifications and treatment options, but by addressing questions that arise during assessment. It covers trauma first aid, examination of the patient, factors that affect treatment planning decisions, and the importance of communicating treatment options and prognosis to traumatized patients.

  5. Quantitative MR imaging in planning and assessing novel cancer treatments Radiotherapy

    CERN Document Server

    Baustert, I C

    2001-01-01

    Novel treatments in cancer, like conformal radiotherapy and anticancer drugs, require new MRI techniques to assess their benefits and potential. In conformal radiotherapy, MRI can be used to measure the shape and dose of the conformed radiation field in dose sensitive gel test-objects thus validating the predicted dose computed by complex programs. In antiangiogenic drug treatment, the vascular dysfunction of the tumour can be assessed by MRI prior to treatment. Response to treatment may also be monitored by measuring the changes in vascular function. In this thesis, MRI of polyacrylamide gels is investigated as a 3D dosimeter for conformal radiotherapy treatment planning. Quantitative MRI sequences capable of measuring the wide range of T2 values typically expected in gel dosimetry, are identified. Different T2 measurement methods are compared in terms of accuracy, signal to noise ratio and acquisition time. Examples of a complex dose distribution in 2D and 3D are presented and compared to the planned dose p...

    Although there have been significant reductions in the number of new HIV infections globally from 2009 to 2013, incidence remains unacceptably high for persons who use drugs. In many settings, women and girls who inject drugs (WWID) with HIV/AIDS experience poor treatment access, including evidence-based practices like antiretroviral therapy and drug treatment. Medication-assisted therapies (MAT) for substance use disorders are especially inaccessible, which in their absence, increases HIV transmission risk. Irrespective of setting or culture, drug treatment using MAT is not only effective but also cost-effective at reducing opioid use and linked injection and sexual risks. Data presented here for WWID address their access to MAT for opioid addiction and to treatments being developed that address the relationship, family, and vocational needs of this group. The most glaring finding is that globally, WWID frequently are excluded in surveys or studies with an impressive lack of disaggregated data by gender when surveying access to MAT—even in wealthy countries. Despite this, there have been some striking improvements in implementing drug treatment as prevention, notably in Iran and China. Still, real barriers remain for women and girls to accessing drug treatment, other harm reduction services, and antiretroviral therapy. Development and/or implementation of interventions that facilitate women and girls engaging in drug treatment that address their roles within society, work, and family/relationships, and outcome evaluation of these interventions are crucial.

    Martyn A. Sharpe

    2015-09-01

    Full Text Available The last major advance in the treatment of glioblastoma multiforme (GBM was the introduction of temozolomide in 1999. Treatment with temozolomide following surgical debulking extends survival rate compared to radiotherapy and debulking alone. However, virtually all glioblastoma patients experience disease progression within 7 to 10 months. Although many salvage treatments, including bevacizumab, rechallenge with temozolomide, and other alkylating agents, have been evaluated, none of these clearly improves survival. Monoamine oxidase B (MAOB is highly expressed in glioblastoma cell mitochondria, and mitochondrial function is intimately tied to treatment-resistant glioblastoma progression. These glioblastoma properties provide a strong rationale for pursuing a MAOB-selective pro-drug treatment approach that, upon drug activation, targets glioblastoma mitochondria, especially mitochondrial DNA. MP-MUS is the lead compound in a family of pro-drugs designed to treat GBM that is converted into the mature, mitochondria-targeting drug, P+-MUS, by MAOB. We show that MP-MUS can successfully kill primary gliomas in vitro and in vivo mouse xenograft models.

    Efforts to increase the number of people having hepatitis C virus (HCV) treatment require understanding how to best deliver services to meet consumers' needs. The general health literature has examined the role that partners can play in supporting health outcomes. This study examines the experiences of couples who inject drugs in relation to knowledge of, decisions about and management of HCV treatment. This is a qualitative interview study of people who inject drugs in couples. Participants were recruited from harm reduction services in two major Australian cities. Couples were interviewed separately. Data were examined using the couple as the unit of analysis and to identify patterns of experience related to the HCV serostatus of couples. Knowledge of HCV and HCV treatment was low and variable but showed some relationship to serostatus. Decisions about HCV treatment were deeply informed by concerns regarding treatment side effects. Positive concordant couples considered 'staging' treatment to ensure that each partner could (in turn) care for the other. People with HCV in serodiscordant relationships may need specific support regarding HCV treatment information. Within positive concordant partnerships, our data indicated the need to support the HCV-positive 'carer' during their partner's treatment. Changing treatment regimens, and their anticipated lower side effect profiles, will need to be actively promoted to ensure that couples understand how these changes affect their treatment options.

    Full Text Available Psoriasis is a chronic inflammatory skin disorder that may drastically impair the quality of life of a patient. Among the various modes of treatments for psoriasis, topical therapy is most commonly used in majority of patients. The topical formulations based on conventional excipients could serve the purpose only to a limited extent. With the advent of newer biocompatible and biodegradable materials like phospholipids, and cutting-edge drug delivery technologies like liposomes, solid lipid nanoparticles (SLNs, microemulsions, and nanoemulsions, the possibility to improve the efficacy and safety of the topical products has increased manifold. Improved understanding of the dermal delivery aspects and that of designing and developing diverse carrier systems have brought in further novelty in this approach. Substantial efforts and the consequent publications, patents and product development studies on the subject are the matter of interest and review of this article. However, majority of the work is related to the preclinical studies and demands further clinical assessment in psoriasis patients.

    National malaria management policy is based upon the availability of effective and affordable antimalarial drugs. This study was undertaken to evaluate the quality of the treatment of uncomplicated malaria cases in Bangui, an area with multidrug-resistant parasites, at a time preceding implementation of a new therapeutic policy relying on the artemisinin derivative combined treatment artemether-lumefantrine. A cross-sectional study was carried out in Bangui city to assess availability of antimalarial drugs and the performances of health workers in the management of uncomplicated malaria. Availability of drugs was recorded in all drugs wholesalers (n = 3), all pharmacies in health facilities (n = 14), private drugstores (n = 15), and in 60 non-official drug shops randomly chosen in the city. Despite a limited efficacy at the time of the survey, chloroquine remained widely available in the official and nonofficial markets. Artemisinin derivatives used in monotherapy or in combination were commonly sold. In health care facilities, 93% of the uncomplicated malaria cases were treated in the absence of any laboratory confirmation and the officially recommended treatment, amodiaquine-sulfadoxine/pyrimethamine, was seldom prescribed. Thus, the national guidelines for the treatment of uncomplicated malaria are not followed by health professionals in Bangui. Its use should be implemented while a control of importation of drug has to be reinforced. PMID:20339579

    The objective of this study is to examine factors among a group of African American and White men in North Carolina and their assessment of prostate cancer treatment choice or belief that treatment chosen was best. A sample of men (N = 877) with a history of prostate cancer diagnosis was recruited from the North Carolina Cancer Registry during 2007-2008 and asked to participate in a telephone interview covering several measures about their initial prostate cancer treatment. Logistic regression was used to assess demographic, psychosocial, and clinical factors on whether they felt that they had chosen the best treatment for the disease. Respondents were majority White (52.7 %), married (75.9 %), and had surgery (67.9 %) as their initial treatment. At the bivariate level, factors associated with the belief that the treatment chosen was best were as follows: White race/ethnicity, higher levels of education, a more recent treatment date, having health insurance coverage, type of treatment received, higher levels of bother from side effects, greater contentment with their quality of life, and doctor discussions of the various treatment options. Similarly, the multivariate analysis showed increased odds of belief that the treatment chosen was the best among demographic (i.e., race/ethnicity, level of education, and health insurance coverage) as well as psychosocial and clinical variables (i.e., greater bother from side effects, greater contentment with their quality of life, and initial treatment received). Results suggest that demographic, psychosocial, and clinical factors play an important role for men in assessing their treatment choices for prostate cancer. PMID:25893926

    Within prison settings, the reliance on punishment for controlling inappropriate or noncompliant behavior is self-evident. What is not so evident is the similarity between this reliance on punishment and the use of positive reinforcements to increase desired behaviors. However, seldom do inmates receive positive reinforcement for engaging in prosocial behaviors or, for inmates receiving drug treatment, behaviors that are consistent with or support their recovery. This study provides an overview of the development and implementation of a positive behavioral reinforcement intervention in male and female prison-based drug treatment programs. The active involvement of institutional staff, treatment staff, and inmates enrolled in the treatment programs in the development of the intervention along with the successful branding of the intervention were effective at promoting support and participation. However, these factors may also have ultimately impacted the ability of the randomized design to reliably demonstrate the effectiveness of the intervention. PMID:22185038

  20. Efficacy of the Oral Fluorouracil Pro-drug Capecitabine in Cancer Treatment: a Review

    2008-08-01

    Full Text Available Abstract: Capecitabine (Xeloda® was developed as a pro-drug of fluorouracil (FU, with the aim of improving tolerability and intratumor drug concentrations through its tumorspecific conversion to the active drug. The purpose of this paper is to review the available information on capecitabine, focusing on its clinical effectiveness against various carcinomas. Identification of all eligible English trails was made by searching the PubMed and Cochrane databases from 1980 to 2007. Search terms included capecitabine, Xeloda and cancer treatment. Nowadays, FDA has approved the use of capecitabine as a first line therapy in patients with metastatic colorectal cancer when single-agent fluoropyrimidine is preferred. The drug is also approved for use as a single agent in metastatic breast cancer patients who are resistant to both anthracycline and paclitaxel-based regimens or when further anthracycline treatment is contraindicated. It is also approved in combination with docetaxel after failure of prior anthracycline-based chemotherapy. In patients with prostate, pancreatic, renal cell and ovarian carcinomas, capecitabine as a single-agent or in combination with other drugs has also shown benefits. Improved tolerability and comparable efficacy, compared with the intravenous FU/LV combination, in addition to its oral administration, make capecitabine an attractive option for the treatment of several types of carcinomas.

    Obesity is an important causative factor in morbidity, disability and premature death. Increasing levels of obesity will impose enormous health, financial and social burdens on worldwide society unless effective interventions are implemented. For many obese individuals, diet and behavioural modification need to be supplemented by pharmacotherapy. Preclinical research has revealed a greater understanding of the complex nature of the hypothalamic regulation of food intake and has generated a wide range of new molecular targets for the development of drug candidates for obesity treatment. As shown by the clinical results that have been obtained with this next generation of therapies, some approaches, for example, fixed-dose drug combinations, have already demonstrated an ability to deliver levels of efficacy that are not achievable with the current antiobesity drug therapies. The regulatory and marketing landscape for development, registration and commercialisation of novel centrally acting drugs for treatment of obesity and related metabolic disorders has changed substantially in recent years. Now a much greater emphasis is placed on tolerability and safety, as well as efficacy. In this review we briefly describe the therapeutic approaches to tackle obesity that are in late-stage clinical development. We then discuss drugs in late-stage development for the treatment of obesity and also future directions. PMID:22410963

    The present study shows the advantages of liposome-based nano-drugs as a novel strategy of delivering active pharmaceutical ingredients for treatment of neurodegenerative diseases that involve neuroinflammation. We used the most common animal model for multiple sclerosis (MS), mice experimental autoimmune encephalomyelitis (EAE). The main challenges to overcome are the drugs' unfavorable pharmacokinetics and biodistribution, which result in inadequate therapeutic efficacy and in drug toxicity (due to high and repeated dosage). We designed two different liposomal nano-drugs, i.e., nano sterically stabilized liposomes (NSSL), remote loaded with: (a) a "water-soluble" amphipathic weak acid glucocorticosteroid prodrug, methylprednisolone hemisuccinate (MPS) or (b) the amphipathic weak base nitroxide, Tempamine (TMN). For the NSSL-MPS we also compared the effect of passive targeting alone and of active targeting based on short peptide fragments of ApoE or of β-amyloid. Our results clearly show that for NSSL-MPS, active targeting is not superior to passive targeting. For the NSSL-MPS and the NSSL-TMN it was demonstrated that these nano-drugs ameliorate the clinical signs and the pathology of EAE. We have further investigated the MPS nano-drug's therapeutic efficacy and its mechanism of action in both the acute and the adoptive transfer EAE models, as well as optimizing the perfomance of the TMN nano-drug. The highly efficacious anti-inflammatory therapeutic feature of these two nano-drugs meets the criteria of disease-modifying drugs and supports further development and evaluation of these nano-drugs as potential therapeutic agents for diseases with an inflammatory component.

    Full Text Available Abstract Background Individual and sociocultural factors may pose significant barriers for drug abusers seeking treatment, particularly for African-American crack cocaine abusers. However, there is evidence that pretreatment interventions may reduce treatment initiation barriers. This study examined the effects of a pretreatment intervention designed to enhance treatment motivation, decrease crack use, and prepare crack abusers for treatment entry. Methods Using street outreach, 443 African-American crack users were recruited in North Carolina and randomly assigned to either the pretreatment intervention or control group. Results At 3-month follow-up, both groups significantly reduced their crack use but the intervention group participants were more likely to have initiated treatment. Conclusion The intervention helped motivate change but structural barriers to treatment remained keeping actual admissions low. Policy makers may be interested in these pretreatment sites as an alternative to treatment for short term outcomes.

    Full Text Available Adverse drug reactions are considered to be among the leading causes of morbidity and mortality. Approximately 5-25% of hospital admissions are due to adverse drug reactions and 6-15% of hospitalized patients experience serious adverse drug reactions, causing significant prolongation of hospital stay. Thus this study was aimed at determining adverse drug reactions by conducting spontaneous reporting in secondary care Govt. District Head Quarters Hospital at Ooty. A prospective Spontaneous Adverse Drug Reaction reporting study was conducted over a period of 12 months from July 2012 to June 2013. The assessment, categorization, causality, severity and preventability were assessed using standard criteria. A total of 47 suspected adverse drug reactions were reported during the study period. Over all incidences was 1.29% among the study population. Antibiotics (31.91% were the class of drug most commonly involved, while ciprofloxacin (14.89% was the most frequently reported. Type H (Hypersensitivity reactions (51.06% accounted for majority of the reports and a greater share of the adverse drug reactions are probable (89.36% based on causality assessment. Mild reactions accounted 82.97% based on modified Hartwig and Siegel severity scale. In 76.59% of the reports, the reaction was considered to be preventable based on Schumock and Thornton preventability scale. The implementation of monitoring based on spontaneous reporting will be useful for the detection and evaluation is associated with increase in morbidity and duration of hospitalization. This study also has established the vital role of clinical pharmacist in the adverse drug reaction monitoring program.

    In this study, we developed the drug-drug interaction (DDI) method as a new assessment technique of intestinal availability (F(G), the fraction of drug transferred from the intestinal enterocytes into the liver, escaping from intestinal metabolism) based on the clearance theory. This method evaluates F(G) from changes caused by DDIs in the area under the blood concentration-time curve and in the elimination half-life of victim drugs. Application of the DDI method to data from the literature revealed that the mean and S.D. of F(G) values for 20 substrate drugs of CYP3A was 0.56 ± 0.29, whereas that for 8 substrate drugs of CYP2C9, CYP2C19, and CYP2D6 was 0.86 ± 0.11. These results were consistent with the fact that intestinal metabolism is mediated predominantly by CYP3A. The DDI method showed reasonable correlations with the conventional i.v./p.o. method and the grape fruit juice (GFJ) method (coefficients of determination of 0.41 and 0.81, respectively). The i.v./p.o. method was more susceptible to fluctuations in the hepatic blood flow rate compared with the DDI and GFJ methods. The DDI method evaluates F(G) separating from the absorption ratio (F(A)) although it requires approximation of F(A). Since preciseness of approximation of F(A) does not greatly affect the evaluation of F(G) by the DDI method, we proposed a reasonable approximation method of F(A) for the evaluation of F(G) in the DDI method. The DDI method would be applicable to a broad range of situations in which various DDI data are utilizable. PMID:25061161

    Aim of this work was to prepare and characterize fluconazole (FLZ) encapsulated ethosomes, incorporate it in suitable dermatological base, and asses its comparative clinical efficacy in the treatment of Candidiasis patients against liposomal gel, marketed product and hydroethanolic solution of the drug. Drug encapsulated ethosomes and liposomes were prepared and optimized by "Hot" method technique and lipid film hydration technique. Vesicular carriers were characterized for % entrapment efficiency, particle size and shape, in vitro drug diffusion study, mean % reduction in dimension of Candidiasis lesion and stability study by using suitable analytical technique. Vesicle size and drug entrapment efficiency of the optimized ethosomes and liposomes were found to be 144 +/- 6.8 nm and 82.68% and 216 +/- 9.2 nm and 68.22% respectively. Microscopic examinations suggest ethosomes to be multilamellar spherical vesicles with a smooth surface. The differential scanning calorimetry results suggest high fluidity of the ethosomes than liposomes. In vitro drug diffusion studies demonstrated that % drug diffused from ethosomes was nearly twice than liposomes and three times higher than the hydroethanolic solution across rat skin. From the clinical evaluation, the developed novel delivery system demonstrated enhanced antifungal activity compared to liposomal formulation, marketed formulation and hydroethanolic solution of the drug.

    Background Glucocorticoid signaling exerts major roles in inflammation, metabolism and depression, which are three crucial factors accompanying or underlying coronary heart disease. Although accumulating evidence indicates the influence of glucocorticoids on the pathology and treatment of coronary heart disease, there is still a dearth of pharmaceutical mechanisms for this relationship. This study aimed to investigate the influence of drug treatment on glucocorticoid receptor levels in coronary heart disease.Methods Eighty hospitalized patients (average age (59.0 7.5) years, 46 male and 34 female) with coronary heart disease were categorized into four groups with 20 members in each according to one of the four drugs they were treated with. The four drugs were: nitrated derivative isosorbide dinitrate, the beta-adrenergic receptor blocker metoprolol, the calcium antagonist nifedipine, and the HMG-CoA reductase inhibitor lovastatin. Glucocorticoid receptor protein levels of peripheral blood lymphocytes were tested using immunoblotting analysis before and after one month of treatment. Results Immunoblotting analysis showed increased glucocorticoid receptor levels after treatment with metoprolol and nifedipine. There were no statistically significant changes of glucocorticoid receptor levels after treatment with isosorbide dinitrate or lovastatin, although there were trends of up-regulation of glucocorticoid receptor expression after both treatments.Conclusions Both the beta-blocker and the calcium blocker can increase glucocorticoid receptor levels after chronic administration. This effect suggests a mechanism for their anti-inflammatory and other therapeutic roles for coronary heart disease and comorbid disorders.

  15. Drug-mediated inhibition of Fli-1 for the treatment of leukemia

    International Nuclear Information System (INIS)

    The Ets transcription factor, Fli-1 is activated in murine erythroleukemia and overexpressed in various human malignancies including Ewing's sarcoma, induced by the oncogenic fusion protein EWS/Fli-1. Recent studies by our group and others have demonstrated that Fli-1 plays a key role in tumorigenesis, and disrupting its oncogenic function may serve as a potential treatment option for malignancies associated with its overexpression. Herein, we describe the discovery of 30 anti-Fli-1 compounds, characterized into six functional groups. Treatment of murine and human leukemic cell lines with select compounds inhibits Fli-1 protein or mRNA expression, resulting in proliferation arrest and apoptosis. This anti-cancer effect was mediated, at least in part through direct inhibition of Fli-1 function, as anti-Fli-1 drug treatment inhibited Fli-1 DNA binding to target genes, such as SHIP-1 and gata-1, governing hematopoietic differentiation and proliferation. Furthermore, treatment with select Fli-1 inhibitors revealed a positive relationship between the loss of DNA-binding activity and Fli-1 phosphorylation. Accordingly, anti-Fli-1 drug treatment significantly inhibited leukemogenesis in a murine erythroleukemia model overexpressing Fli-1. This study demonstrates the ability of this drug-screening strategy to isolate effective anti-Fli-1 inhibitors and highlights their potential use for the treatment of malignancies overexpressing this oncogene

    Seven of the 13 Principles of Drug Addiction Treatment disseminated by the National Institute on Drug Abuse (NIDA) were meta-analyzed as part of the Evidence-based Principles of Treatment (EPT) project. By averaging outcomes over the diverse programs included in EPT, we found that five of the NIDA principles examined are supported: matching treatment to the client’s needs; attending to the multiple needs of clients; behavioral counseling interventions; treatment plan reassessment; and counseling to reduce risk of HIV. Two of the NIDA principles are not supported: remaining in treatment for an adequate period of time and frequency of testing for drug use. These weak effects could be the result of the principles being stated too generally to apply to the diverse interventions and programs that exist or of unmeasured moderator variables being confounded with the moderators that measured the principles. Meta-analysis should be a standard tool for developing principles of effective treatment for substance use disorders. PMID:22119178

    Injection drug use accounts for most of the incident infections with hepatitis C virus (HCV) in the United States and other developed countries. HCV infection is a complex and challenging medical condition in injection drug users (IDUs). Elements of care for hepatitis C in illicit drug users include prevention counseling and education; screening for transmission risk behavior; testing for HCV and human immunodeficiency virus infection; vaccination against hepatitis A and B viruses; evaluation for comorbidities; coordination of substance-abuse treatment services, psychiatric care, and social support; evaluation of liver disease; and interferon-based treatment for HCV infection. Caring for patients who use illicit drugs presents challenges to the health-care team that require patience, experience, and an understanding of the dynamics of substance use and addiction. Nonetheless, programs are successfully integrating hepatitis C care for IDUs into health-care settings, including primary care, methadone treatment and other substance-abuse treatment programs, infectious disease clinics, and clinics in correctional facilities.
