Intervention to achieve alcohol abstinence represents the most effective treatment for alcoholic patients with liver cirrhosis. However no trials have evaluated the efficacy of anti-craving drugs in these patients because of the concern that these medications might worsen liver disease. Baclofen is effective to reduce alcohol craving improving abstinence in alcohol-dependent patients. It is mainly eliminated by kidney. No hepatic side-effects have been reported in treated patients. The present study investigates the efficacy and safety of baclofen in achieving and maintaining abstinence in alcoholic cirrhotic patients.
