Mesuximide (or methsuximide, methosuximide) is a 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 methosuximide is largely due to its pharmacologically active metabolite, N-desmethylmethosuximide, which has a longer half-life and attains much higher plasma levels than its parent.^[3]
