Mephenytoin (Mesantoin®) is an anticonvulsant medication used to treat epilepsy and it is particularly effective in tonic-clonic epilepsy . Its common chemical name is 3-methyl 5,5-phenyl-ethyl-hydantoin and its IUPAC chemical name is 5-ethyl-3-methyl-5-phenylimidazolidine-2,4-dione. It has pharmacological effects similar to phenytoin and the barbiturates.

Mechanism of action

The mechanism of action of mephenytoin is not definitely known, but extensive research strongly suggests that its main mechanism is to block frequency-, use- and voltage-dependent neuronal sodium channels, and therefore limit repetitive firing of action potentials.[1]
