Topiramate Treatment of Problem Drinkers

Completed · Phase 4 · Has a placebo group

Conditions studied: Alcohol Drinking

In brief

The purpose of this study is to evaluate the safety and efficacy of topiramate in reducing drinking and heavy drinking frequency in problem drinkers. We hypothesize that at a dosage of up to 200mg/day, topiramate will be well tolerated in this patient population and that, compared to placebo treatment, topiramate will result in a greater reduction in the frequency of both drinking days and heavy drinking days.
