To assess the possible relationship between the metabolic disposition of pantoprazole and genetically determined S-mephenytoin 4'-hydroxylation phenotype and genotype. The pharmacokinetic disposition of pantoprazole was investigated in 14 Japanese male volunteers (seven extensive and seven poor metabolizers of S-mephenytoin). All

The preferential hydroxylation of (S)-mephenytoin to 4'-hydroxymephenytoin (4'-OH-M) displays a genetic polymorphism of drug metabolism in humans. Thus the excreted 4'-OH-M is considered to be an important marker for the hepatic (S)-mephenytoin 4'-hydroxylase. Accordingly, a mixture of urine containing total
