A non-invasive urine analysis method to determine the in-vivo flavin-containing mono-oxygenase (FMO) activity catalysing N-oxidation of ranitidine (RA) was developed and used to phenotype a Korean population. FMO activity was assessed by the molar concentration ratio of RA and RANO

We have previously reported an association of impaired S-oxidation with primary biliary cirrhosis. In order to confirm and further define this relationship, we retested S-oxidation capacity via three metabolic pathways and sulphation capacity via a fourth pathway. Metabolism of S-carboxymethyl-L-cysteine

Ranitidine and its main metabolites, ranitidine N-oxide and ranitidine S-oxide, were determined in plasma and urine after separation using reversed-phase liquid chromatography. The mobile phase consisted of an initial isocratic step with 7:93 (v/v) acetonitrile-7.5 mM phosphate buffer (pH 6)

Journal of chromatography, 323(1), 143-152 (1985-04-17)
Reversed-phase high-performance liquid chromatography systems for the separation of ranitidine and its metabolites ranitidine-N-oxide, ranitidine-S-oxide, and desmethylranitidine have been developed for use in high-performance liquid chromatography-mass spectrometry. A direct liquid introduction-high-performance liquid chromatography-mass spectrometry system to analyse qualitatively and quantitatively
