About this study

Background: Chronic heavy drinking can cause alcohol use disorder (AUD). AUD changes how the brain works. People with AUD may drink compulsively or feel like they cannot control their alcohol use. Acamprosate is an FDA-approved drug that reduces anxiety and craving in some, but not all, people with AUD. Objective: To learn more about how acamprosate affects brain function in people with AUD. Eligibility: People aged 21 to 65 years with moderate to severe AUD. Design: Participants will stay in the clinic for 21 days after a detoxification period of approximately 7 days. Acamprosate is a capsule taken by mouth. Half of participants will take this drug 3 times a day with meals. The other half will take a placebo. The placebo looks like the study drug but does not contain any medicine. Participants will not know which capsules they are taking. Participants will have a procedure called electroencephalography (EEG): A gel will be applied to certain locations on their scalp, and a snug cap will be placed on their head. The cap has sensors with wires. The sensors detect electrical activity in the brain. Participants will lie still and perform 2 tasks: they will look at different shapes and press a button when they see a specific one; and they will listen to tones and press dedicated buttons when they hear the corresponding tones. Participants will have 2 EEGs: 1 on day 2 and 1 on day 23 of their study participation. They may opt to have up to 4 more EEG studies (one on day …
