Alcohol Use Disorder
Conditions
Brief summary
This study will examine the efficacy of the medication gemfibrozil in reducing alcohol consumption in individuals with an alcohol use disorder who are seeking treatment for alcohol-related problems. Twenty individuals will be randomized to receive four weeks of either gemfibrozil or placebo and retrospective reports of alcohol use will be collected throughout the trial. In addition, brain imaging measures will be collected at baseline and after two weeks of treatment to determine the effects of gemfibrozil on brain functioning.
Interventions
Gemfibrozil capsules (600 mg) taken twice per day
Microcrystalline cellulose powder packaged in capsules identical to the experimental medication
