Phenacemide
Anticonvulsant
Phenacemide (INN, BAN) (brand name Phenurone), also known as phenylacetylurea, is an anticonvulsant of the ureide (acetylurea) class.[1] It is a congener and ring-opened analogue of phenytoin (a hydantoin),[2][3] and is structurally related to the barbiturates and to other hydantoins.[4] Phenacemide was introduced in 1949 for the treatment of epilepsy, but was eventually withdrawn due to toxicity.[2][3]
