This study will help to determine whether the medication, topiramate, reduces alcohol use among adolescents with alcohol dependence. It will also help answer the question, "How does topiramate reduce drinking in teenagers?" Understanding how topiramate may reduce drinking in adolescents would allow for a more targeted pharmacotherapeutic approach to treatment and help to identify additional medications that may hold promise for improving treatment outcomes for youth.
