Acute Interaction of Baclofen in Combination With Alcohol in Heavy Social DrinkersAlcoholism: Clinical and Experimental Research Published Online: 6 Oct 2008
There is growing evidence that gamma-amino butyric acid-B receptor agonists may be effective in the treatment of alcohol abuse or dependence. The primary goal of this study was to determine the safety of baclofen in combination with alcohol consumption in heavy drinkers. In addition, the effects of baclofen alone, and in combination with alcohol, on subjective effects, cognitive performance effects, as well as alcohol craving, were assessed.
Baclofen, either alone or in combination with alcohol, produced only modest increases in heart rate and blood pressure and no adverse effects were reported. Baclofen did not increase positive subjective effects (e.g., Stimulant effects, Drug Liking) but did increase sedation and impair performance. Even though both baclofen and alcohol impaired performance, for the most part performance was not impaired to a greater extent when baclofen was combined with alcohol. Among this population of nondependent drinkers, baclofen did not alter alcohol craving or alcohol-induced positive subjective effects.
Baclofen alone has minimal abuse liability in heavy social drinkers, and baclofen is relatively well tolerated and safe when given in combination with intoxicating doses of alcohol.
