Naltrexone Improves Quit Rates Attenuates Smoking Urge and Reduces Alcohol Use in Heavy Drinking Smokers Attempting to Quit Smoking

摘要

BackgroundHeavy drinking smokers (HDS) have more difficulty quitting smoking than lighter drinkers or abstainers. The opioid antagonist naltrexone may improve smoking quit rates and reduce alcohol use in drinker–smokers, but its relative efficacy in smokers with a range of drinking patterns is unknown. The current study tested the hypothesis that HDS would show differential benefit of naltrexone versus placebo relative to moderate-to-light or nondrinking smokers in terms of improving smoking outcomes and reducing alcohol consumption.
