Omeprazole, high-performance liquid chromatography

Cass, Q.B., Lima, V.V., Oliveira, R.V., Cassiano, N.M., Degani, A.L.G., Pedrazzoli, P., Jr. (2003). Enantiomeric determination of the plasma levels of omeprazole by direct plasma injection using high-performance liquid chromatography with achiral-chiral columnswitching. J. Chromatogr. B 798, 275-281. [Pg.339]

High-performance liquid chromatography Persson et al. [57] determined omeprazole and three of its metabolites, the sulfone, the sulfide, and the hydroxy metabolite, in plasma and urine by liquid chromatographic methods. The compounds are extracted from the biological sample and the extract is subjected to liquid chromatographic separation, either directly or after evaporation of the organic solvent and dissolution...
