Topiramate in the treatment of alcohol dependence: a meta-analysis.

[Article in English, Spanish]

Author information

Mental Health Unit Hospital Laredo Cantabria, Spain.


Several controlled clinical trials have studied the efficacy of topiramate in the treatment of alcoholism. In this paper, we have performed a meta-analysis of those trials in which topiramate was compared with placebo and then we reviewed its efficacy in trials in which it was compared with other drugs.


A quantitative synthesis of data was per-formed using inverse variance weighting in a random effects model.


Based on three placebo-controlled trials, topiramate is more efficacious than placebo in reducing the percentage of heavy drinking days (23.2%, 95% confidence interval [CI]: 15.7 to 34.4), increasing the number of days of abstinence (mean difference: 2.9 days, 95% CI: 2.5 to 3.3),and lowering the logarithm of g-GT levels (mean difference:0.075 95% CI: 0.048 to 0.118). Two trials suggested that topiramate is also more efficacious than naltrexone, and one open-label study reported better results for disulfiram than for topiramate.


Topiramate can be used in alcohol dependence. Adverse effects such as paresthesia or insomnia should be taken into account when prescribing topiramate.Its optimal dosage requires further research.
