Psychiatric uses of topiramate : what is the current evidence?

Abstract

Topiramate enhances gamma-amino-butyric acid effects, has antiglutaminergic effects, and is a state-dependent sodium channel blocker. It is registered as an adjunctive treatment for epilepsy but is not registered for psychiatric indications. Nevertheless, it may be useful beyond its initial indication, considering the promising literature on which I report below. However, much more research evidence is needed to establish sufficient scientific justification for prescribing it routinely for psychiatric purposes.
