The antiepileptic drug mephenytoin is a racemate. Mephenytoin hydroxylation is a stereospecific reaction and is confined to the S-enantiomer, which is normally eliminated within hours, allowing the R-enantiomer to accumulate since it can be eliminated only within days or weeks.

We investigated the conversion of mephenytoin to nirvanol in five patients with uncontrolled complex partial seizures. After a 50-mg single oral dose, mean peak mephenytoin level was 0.48 microgram/ml and nirvanol 0.37 microgram/ml. After 400 mg, peak mephenytoin level was

The stereoselective clearances of R- and S-mephenytoin were determined in rats receiving either an intravenous or hepatic portal vein infusion of racemic mephenytoin. The mean +/- SD intravenous clearances of R- and S-mephenytoin were 1630 +/- 250 ml/hr and 630

A gas chromatographic method was developed for the determination of the R- and S- enantiomers of the anticonvulsant, mephenytoin, and its N-demethylated metabolite, 5-phenyl-5- ethylhydantoin ( PEH ), in plasma and blood. Direct enantiomeric separation of mephenytoin and its internal
T Inaba et al.
American journal of human genetics, 38(5), 768-772 (1986-05-01)
A genetic polymorphism characterized by deficient drug oxidation exists for the hydroxylation of mephenytoin. This deficiency was first recognized in a family study that suggested an autosomal recessive pattern of inheritance. To confirm the observation, we investigated 28 relatives of
