A high-performance liquid chromatographic assay is described for the separation and quantification of nadolol isomers in human plasma. The isomers were quantified using reverse-phase HPLC and fluorometric detection after derivatization with the chiral reagent R(-)-1-(naphthyl)ethylisocyanate [R(-)-NEI]. The N-isopropyl analogue (one

A sensitive, stereospecific high-performance liquid chromatographic assay for oxprenolol enantiomers in rat plasma was developed, using a chiral derivatization agent. Racemic oxprenolol and the internal standard (racemic propranolol) are extracted with dichloromethane after alkalinization of the plasma. Quantitation of R(+)-
