A sensitive and selective high-performance liquid chromatographic method for the determination of reboxetine enantiomers in human plasma was developed. Although two chiral centres are present in reboxetine, its stereospecific synthesis leads to two rather than four possible enantiomers. After extraction

A sensitive, stereoselective and rapid reversed-phase liquid chromatographic method for the determination of (SR)- and (RS)-mefloquine enantiomers in 100 microliters plasma and capillary blood collected on chromatographic paper is presented. The assay involves protein precipitation from plasma, liquid-liquid extraction of
