title: Stereospecific high-performance liquid chromatographic analysis of warfarin in plasma.
abstract: A stereospecific high-performance liquid chromatographic assay has been developed to determine R(+)- and S(-)-warfarin simultaneously in plasma. The method involved the formation of diastereoisomeric esters, using carbobenzyloxy-L-proline, with subsequent separation using silica as the stationary phase. The method permits characterization of the pharmacokinetics of warfarin enantiomers following administration of racemic drug.
