The quest for an effective medication therapy for problem gambling remains an important priority for the problem gambling treatment research field. While several medications have been evaluated in controlled clinical trials, no medication has been shown to unequivocally reduce gambling behaviour and, to date, no medication has been approved for treating this disorder. Recently, topiramate, indicated for the treatment of seizure disorders, has shown some promise as a medication therapy for problem gambling. In this project, the efficacy of topiramate will be evaluated in a placebo-controlled clinical trial, the first study to do so. The interaction of the effects of the medication and gambling sub-type will be examined to determine whether the efficacy of topiramate is correlated with the specific biopsychosocial history of the gambler.
