<unk>  is metabolized by CYP3A4 and CYP2C19, two isoenzymes of the cytochrome P450 system. Drugs that inhibit CYP3A4, such as itraconazole, erythromycin, ketoconazole, and diltiazem, are known to interact with<unk> . The proton pump inhibitor omeprazole, an inhibitor of CYP2C19, increases exposure to the active metabolite of<unk> . A single report has been made of grapefruit juice possibly increasing the effects of<unk> ; some drug information sources list this as a possible interaction. The FDA-approved labeling of<unk>  notes that grapefruit juice (which is a CYP3A4 inhibitor) increases the drug's maximum concentration by around 50%.
