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
