Metabolite Identification
Common Namep-Hydroxyl-ethotoin
Descriptionp-Hydroxyl-ethotoin is a metabolite of ethotoin. 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. (Wikipedia)
