The metabolic pathways of most xenobiotics and endogenous compounds can be divided into phase 1 (oxidative, reductive, and hydrolytic) and phase 2 (glucuronidation, sulfate conjugation, glycine and glutathione conjugation, and acetylation and methylation) processes. Oxidative metabolism by the cytochrome P450 system has been intensively investigated compared with glucuronidation and other conjugation pathways. The primary aim of this study was to evaluate the disposition of olanzapine or risperidone in healthy volunteers with and without coadministration of the uridine diphosphoglucuronate-glucuronosyltransferase inhibitor probenecid. We hypothesized that olanzapine disposition would be altered as a result of decreased glucuronidation, whereas risperidone disposition would be relatively unaffected.
