Background: Previously, our group has shown that topiramate, a sulfamate-substituted fructopyranose derivative, is an effective treatment for alcohol dependence. Herein, we extend that proof-of-concept study by determining whether cigarette-smoking, alcohol-dependent individuals from the earlier study also experienced improved smoking outcomes. Methods: As a subgroup analysis of a larger double-blind, randomized, controlled, 12-week study comparing topiramate vs placebo as treatment for alcohol dependence, a 12-week clinical trial compared topiramate vs placebo in 94 cigarette-smoking, alcohol-dependent individuals. Of these, 45 were assigned to receive topiramate (escalating dose from 25 to 300 mg/d) and the remaining 49 had placebo as an adjunct to weekly standardized medication compliancemanagement.Theprimaryoutcomewassmoking cessation ascertained by self-report and confirmed by the level of serum cotinine (nicotine's major metabolite). Results: Topiramate recipients were significantly more likely than placebo recipients to abstain from smoking (odds ratio, 4.46; 95% confidence interval, 1.08-18.39; P=.04). Using a serum cotinine level of 28 ng/mL or lower to segregate nonsmokers from smokers, we found that the topiramate group had 4.97 times the odds of being nonsmokers (95% confidence interval, 1.1-23.4; P=.04). Smoking cessation rates for topiramate recipients were 19.4% and 16.7% at weeks 9 and 12, respectively, compared with 6.9% at both time points for placebo recipients. Conclusion: In this trial, topiramate (up to 300 mg/d) showed potential as a safe and promising medication for the treatment of cigarette smoking in alcohol-dependent individuals.
