Aripiprazole is metabolised mainly by CYP2D6 and CYP3A4:
- Strong CYP2D6 inhibitors (e.g., fluoxetine, paroxetine) and strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, some HIV protease inhibitors): can increase aripiprazole levels
- Strong CYP3A4 inducers (e.g., carbamazepine, phenytoin, rifampicin, St John's wort): can decrease aripiprazole levels
- Antihypertensives: increased risk of hypotension.
