Abstract: Topiramate is an anticonvulsant drug used for the treatment of epilepsy and prophylaxis of migraine. Some authors have proposed its use as a mood stabilizer and have reported its efficacy in reducing impulsiveness and improving mood regulation, possibly via its antagonism to glutamatergic transmission in the lateral hypothalamus, although this indication is still controversial. Weight loss is a side effect consistently reported in the medical literature in patients treated with topiramate. Given its potential role in stabilizing mood and reducing impulse control problems and weight, topiramate has been proposed as a treatment for obese patients with binge eating disorder (BED). The aim of this paper is to review published data on the efficacy and safety of topiramate for the treatment of obese subjects with BED. Although the evidence is preliminary, topiramate appears to be a relatively safe and effective treatment for obese subjects with BED. Limitations of the studies and future directions for research are discussed.
