BACKGROUND Naltrexone and acamprosate have been shown to be effective in relapse prevention of alcoholism via different pharmacologic mechanisms. Since it remains uncertain whether both substances are equally efficient and whether a combination of both drugs potentiates the efficacy, we conducted the first published controlled study comparing and combining both compounds. METHODS After detoxi...

This double-blinded, placebo-controlled trial evaluated the efficacy of naltrexone as an adjunct to standard smoking cessation treatment. Participants (N = 110) were adult male and female nicotine-dependent smokers who expressed interest in quitting smoking. All subjects received six sessions of behavioral counseling (1 hr/session for 6 weeks), and 1 month of the nicotine patch (21 mg for the f...

This study examined whether the opioid receptor antagonist naltrexone is efficacious in smoking cessation and whether sex moderates the response. We assessed smoking quit rates and weight gain in a double-blind randomized trial comparing oral naltrexone (n = 162) with placebo (n = 154) in nicotine-dependent participants who wanted to quit smoking. The medication was gradually titrated up to 50 ...

AIMS To determine the efficacy of naltrexone in reducing illicit opioid use and the potential moderating role of treatment retention. DESIGN First, randomized controlled trials (RCTs) comparing the regimens of treatment using the opioid antagonist, naltrexone, with controls were analysed by meta-analysis for treatment effect with regard to a range of outcome criteria. The degree of heterogene...

This study tested the hypothesis that stimulants (indirect dopamine agonists) attenuate the discriminative stimulus of naltrexone in monkeys chronically treated with L-alpha-acetylmethadol (LAAM). Four rhesus monkeys (Macaca mulatta) received LAAM (1.0 mg/kg s.c.) twice daily and discriminated a withdrawal-precipitating dose of naltrexone (0.0178 mg/kg s.c.) from saline. Cocaine (0.1-1.78 mg/kg...

drug abuse is a problem that causes a wide array of social, emotional, and physical problems and involves both patients and the society. helping the addicted has always been a priority for physicians and especially psychiatrists. the purpose of this prospective study was to compare the effects of methadone and naltrexone in general well-being of patients undergoing these treatments.forty-six pa...

Abstract Background: This study compared the success rates of buprenorphine and clonidine in detoxification of heroin-dependents and evaluated the recurrence of drug abuse in patients taking naltrexone in a 6 month follow up. Methods: A double-blind study was carried out in Kerman’s psychiatric hospital on heroin-dependents seeking detoxification during the years 2007-2009.These patient...

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 perform...

AIMS Although debates over the efficacy of oral naltrexone and acamprosate in treating alcohol use disorders tend to focus on their global efficacy relative to placebo or their efficacy relative to each other, the underlying reality may be more nuanced. This meta-analysis examined when naltrexone and acamprosate are most helpful by testing: (i) the relative efficacy of each medication given its...

It has been suggested that an opioidergic feeding pathway exists between the nucleus of the solitary tract (NTS) and the central nucleus of the amygdala. We studied the following three groups of rats: 1) artificial cerebrospinal fluid (CSF) infused in the NTS, 2) naltrexone (100 microg/day) infused for 13 days in the NTS, and 3) artificial CSF infused in the NTS of rats pair fed to the naltrexo...
