Ethotoin (marketed as Peganone® by Ovation) is an anticonvulsant drug used in the treatment of epilepsy. It is a hydantoin, similar to phenytoin. Ethotoin lacks phenytoin's side effects of gingival hyperplasia and hirsutism, however it is less effective. This, combined with the need for frequent dosing has limited its usefulness. Ethotoin is no longer widely used.
