| Description | Phensuximide, also known as milontin, belongs to the class of organic compounds known as phenylpyrrolidines. These are polycyclic aromatic compounds containing a benzene ring linked to a pyrrolidine ring through a CC or CN bond. Pyrrolidine is a five-membered saturated aliphatic heterocycle with one nitrogen atom and four carbon atoms. Phensuximide is a drug which is used for the treatment of epilepsy. Based on a literature review a significant number of articles have been published on Phensuximide. |
