Nirvanol, also known as ethylphenylhydantoin, is a derivative of hydantoin with anticonvulsant properties. Its 5-ethyl-5-phenyl substitution pattern is similar to that of phenobarbital.[2] It is useful in the treatment of chorea.[3]
Metabolism
Metabolism of nirvanol is stereoselective, with the S enantiomer undergoing roughly 14 times more hydroxylation at the 4 position of the phenyl group than the R enantiomer.[4][5]
