Untargeted Metabolomics Reveal New Endogenous Plasma Biomarkers Associated with CYP3A Inhibition in Humans.
Reliable endogenous biomarkers for assessing CYP3A activity and clinical drug-drug interaction (DDI) risk remain limited. We characterized global metabolomic changes following itraconazole treatment in a fixed-sequence DDI study (11 healthy volunteers) to identify novel CYP3A endogenous biomarkers. Untargeted metabolom...
