Abstract
Stereoselective metabolism and inhibitory potential of lansoprazole enantiomers were evaluated from the incubational studies of human liver microsomes and eDNA-expressed CYP isoforms in vitro. The formation of lansoprazole sulfone from both enantiomers appeared to be catalyzed by single and low affinity enzyme. Lansoprazole 5-hydroxylation, however, appeared to be mediated by two kinetically distinct CYP enzymes.(omitted)
