BACKGROUND There is an unmet need for safe and effective medicines to treat children with Crohn's disease. Recently, investigations have shown an association between endogenous opioid peptides and inflammatory cells. AIMS The aims of this study were to evaluate the safety and tolerability of an opioid antagonist, naltrexone, in children with moderate to severe Crohn's disease. METHODS A pil...

The objective of this study was to review the evidence for the efficacy and toxicity of naltrexone, a treatment of alcohol dependence. A systematic review and meta-analysis of randomized controlled trials of naltrexone used in the treatment of alcohol dependence was conducted. We searched MEDLINE, EMBASE, PsychLIT and the Cochrane Controlled Trials Registry for articles published between 1976 t...

Background:Naltrexone is a competitive opioid receptor antagonist blocking the euphoric effects of exogenous opioids. When used concomitantly with opioids, naltrexone causes severe withdrawal symptoms.The main aim of the study is to determine the symptomatology and outcome of patients who consumed naltrexone in conjunction with an opioid substance. Methods:This cross-sectional study was perf...

objective: management of borderline personality disorder (bpd) is a difficult challenge due to the complex features of this disorder. this article reviews the use of naltrexone in the treatment of bpd. methods: published articles and clinical trials were searched in google scholar, medline, elsevier, and cochrane database of systematic reviews abstracts in english language between 1990 and 2017...

CONTEXT Oral naltrexone can completely antagonize the effects produced by opioid agonists. However, poor compliance with naltrexone has been a major obstacle to the effective treatment of opioid dependence. OBJECTIVE To evaluate the safety and efficacy of a sustained-release depot formulation of naltrexone in treating opioid dependence. DESIGN AND SETTING Randomized, double-blind, placebo-c...

background: naltrexone, an opioid receptor antagonist shifts the immune response toward a th1 profile. in the current study, we evaluated the efficacy of the mixture of ntx and alum, as a new adjuvant, to enhance immune response and induce protection against leishmania major in a mouse model. methods : balb/c mice were immunized three times either autoclaved l. major promastigotes’ antigens alo...

background: agitation is an early symptom of the acute opioid withdrawal syndrome in addicts that may start by inappropriate use of naltrexone. the current drug interventions are not efficient or need critical care as well. this study compares the clinical role of midazolam and diazepam for the management of agitation due to inappropriate use of naltrexone. materials and methods: in this double...

BACKGROUND Naltrexone has considerable potential in helping to prevent relapse in heroin dependency. A longer-lasting formulation for naltrexone treatment is desirable to further reduce non-adherence and relapse during treatment of opiate dependence. AIMS To evaluate the safety and effectiveness of a 6-month naltrexone implant in reducing opioid use after in-patient treatment. METHOD A grou...

There is preclinical support for using NMDA receptor glutamatergic antagonists to aid in naltrexone-based treatment of opioid dependence. We hypothesized that adding memantine will improve efficacy of extended-release (XR) naltrexone to prevent relapse. In this double blind study opioid-dependent participants (N=82) underwent inpatient detoxification and naltrexone induction. During naltrexone ...

To determine the duration of blockade of mu-opiate receptors by naltrexone, we measured the binding of [11C]carfentanil in the brain of five normal volunteers with a positron radiation detection system before and 1, 48, 72, 120, and 168 hr after naltrexone administration. The half-time of blockade by naltrexone in the brain ranged from 72 to 108 hr which is greater than the fast plasma clearanc...
