Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/22512548

Phenacemide, also known as phenylacetylurea, is an anticonvulsant of the ureide (acetylurea) class. Phenacemide was introduced in 1949 for the treatment of epilepsy, but was eventually withdrawn from the market because of its severe side effects, which includes personality changes, blood, renal and skin disorders.
