Topiramate for the treatment of alcohol dependence: comparison with naltrexone.

BACKGROUND

A 6-month naturalistic, randomized and open-label, trial of topiramate versus naltrexone was conducted, with assessments at enrollment and after 3 and 6 months of treatment. 182 alcohol-dependent patients who had been drinking heavily during the past month were included.

METHODS

Outcome was measured using tools that assessed alcohol intake, cravings, disability, and quality of life; changes in biomarkers of alcohol intake were also used.

RESULTS

At the 6-month evaluation, patients taking topiramate had significantly lower scores on the OCDS (all subscales), the EuropASI (medical, alcohol, family/social, and psychiatric) and the WHO/DAS (employment/social). More patients taking topiramate remained in the abstinence group and the moderate drinking without problems group.

CONCLUSIONS

Topiramate at a mean dose of 200 mg/day was better than naltrexone at a mean dose of 50 mg/day at reducing alcohol intake and cravings throughout the study.
