TOPAMAX (topiramate) is an oral small-molecule anticonvulsant approved in 1996 that functions as a cytochrome P450 3A4 inducer. While originally developed for epilepsy, it has been widely used off-label and in approved indications across neurology and psychiatry. The drug's mechanism involves enzyme induction, which affects drug-drug interactions and requires careful patient management.
