研究概览
简要总结
The purpose of the study is to evaluate the efficacy, safety and tolerability of nalmefene in the treatment of alcohol dependence.
详细描述
Alcohol dependence is a maladaptive pattern of alcohol use, leading to clinically significant impairment or distress, as manifested by at least three of a number of criteria such as tolerance, withdrawal symptoms, frequent use of alcohol in larger amounts or over longer periods than was intended, and others. Excessive intake of alcohol reduces the life span by a decade, and alcohol drinking is strongly related to mortality from liver cirrhosis, chronic pancreatitis, certain cancers, hypertension, accidents and violence. This study is planned to evaluate the efficacy and safety of as-needed use of nalmefene 18.06 mg versus placebo in decreasing monthly Heavy Drinking Days (HDDs) and decreasing the total consumption during a period of 6 months in adult patients with alcohol dependence.
