Mesuximide (or methsuximide) is an succinimide anticonvulsant medication. It is sold as a racemate by Pfizer under the tradenames Petinutin (Switzerland)[1] and Celontin (United States).[2] The therapeutic efficacy of methsuximide is largely due to its pharmacologically active metabolite, N-desmethylmethsuximide, which has a longer half-life and attains much higher plasma levels than its parent.[3]
