Omeprazole, high-performance liquid

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]

Riedel and Leopold [35] investigated the degradation of omeprazole in organic polymer solutions and aqueous dispersions of enteric-coating polymers by UV spectroscopy. Data were compared with those obtained in a previous high-performance liquid chromatographic (HPLC) study. For comparative purposes the cationic Eudragit RS 100 and the monomeric acid acetic acid were included in this study. The discolorations of... [Pg.207]

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...
