PRODUCT INTRODUCTION

description

Ethosuximide is a dicarboximide that is pyrrolidine-2,5-dione in which the hydrogens at position 3 are substituted by one methyl and one ethyl group. An antiepileptic, it is used in the treatment of absence seizures and may be used for myoclonic seizures, but is ineffective against tonic-clonic seizures. It has a role as an anticonvulsant, a geroprotector and a T-type calcium channel blocker. It is a pyrrolidinone and a dicarboximide.
