Detection of 5-(3, 4-Dihydroxy-1, 5-Cyclohexadien-1-Yl) -5-Phenylsydantoin as a Major Metabolite of 5, 5-Diphenylhydantoin (Dilantin) in the Newborn Human

Abstract

Abstract The metabolism of 5, 5-diphenylhydantoin was studied in the newborn human in two instances; one involved direct administration of the drug, and the other was by placental transfer of the drug from the mother. 5-(3,4-Dihydroxy-1, 5-cyclohexadien-1-yl)-5-phenylhydantoin was found to be a major metabolite. The GC and GC-MS methods employed here are well suited to the problem of studying drug metabolism in the newborn.
