Study Overview
Brief Summary
The efficacy, safety, and dose-response of nalmefene hydrochloride at 10 mg and 20 mg in patients with alcohol dependence will be evaluated in a multicenter, randomized, double-blind, placebo-controlled, 3-parallel-group comparative trial. The superiority of nalmefene hydrochloride at 20 mg to placebo will be verified in terms of reduction of alcohol consumption.
