Biomedical chromatography : BMC, 9(3), 140-145 (1995-05-01)
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 procedure for the concurrent determination of the (+)- and (-)-enantiomers of sotalol in plasma using high-performance liquid chromatography of diastereomeric derivatives is described. Sotalol is extracted from a 0.5-ml aliquot of plasma at pH 9.3 using ethyl acetate. Atenolol

A sensitive high-performance liquid chromatographic assay was developed for the determination of tocainide enantiomers in plasma. Following extraction of tocainide from plasma, the enantiomers were derivatized with S-(+)-1-(1-naphthyl)ethylisocyanate. The resulting diastereomers were separated and quantified using normal-phase chromatography with fluorescence

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(+)-
