B F Bourgeois et al.
Epilepsia, 27(4), 412-418 (1986-07-01)
Stereoselective metabolism has been demonstrated for mephenytoin (MHT), R-MHT being demethylated to the pharmacologically active metabolite 5-phenyl-5-ethylhydantoin (PEH; nirvanol), and S-MHT undergoing aromatic hydroxylation to 4-OH-MHT, with formation of an intermediate arene oxide metabolite. PEH is responsible for the therapeutic

Journal of inorganic biochemistry, 42(4), 267-272 (1991-06-01)
The preparation and spectral properties of copper(II) complexes of two hydantoins are reported. Complexes of the general formula Cu(hyd)2(py)2, where hyd = phenytoin or nirvanol; and py = pyridine were prepared and characterized by infrared and ESR. Spectral data show

Journal of pharmacobio-dynamics, 9(3), 303-314 (1986-03-01)
Disposition of 1-benzenesulfonyl-5,5-diphenylhydantoin (II) having a potent anti-inflammatory activity was compared with that of 5,5-diphenylhydantoin (I), an antiepileptic drug, in order to elucidate whether the pharmacodynamic difference between them can be explained by their physicochemical and pharmacokinetic properties. After oral

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.
W H Theodore et al.
Neurology, 34(8), 1100-1102 (1984-08-01)
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
