title: Rapid chiral separation of metoprolol in plasma--application to the pharmacokinetics/pharmacodynamics of metoprolol enantiomers in the conscious goat.
abstract: The plasma concentrations of metoprolol enantiomers have been determined by means of a direct phenyl carbamate-cellulose-based chiral high performance liquid chromatography assay using fluorimetric detection. This assay has been used to investigate the pharmacokinetics and pharmacodynamics of metoprolol enantiomers in the conscious goat. There is evidence that the pharmacokinetics of metoprolol in the goat occurs stereoselectively and that enantiomer-enantiomer pharmacokinetic interactions occur. R-Metoprolol is less effective in reducing the mean arterial blood pressure than S- and R/S-metoprolol.
