Consumer information for this interaction is not currently available.ADJUST DOSE: Coadministration with potent inhibitors of CYP450 3A4 may significantly increase the plasma concentrations and risk of adverse effects of istradefylline, which is primarily metabolized by CYP450 3A4 and 1A1. In study subjects, administration of a single 40 mg dose of istradefylline with the potent CYP450 3A4 inhibitor ketoconazole (200 mg twice daily for 4 days) increased the total systemic exposure (AUC(inf)) of istradefylline by 2.5-fold. MANAGEMENT: The manufacturer suggests that the maximum dose of istradefylline when coadministered with potent CYP450 3A4 inhibitors be reduced to 20 mg once daily. Patients should be monitored for adverse effects including dyskinesia, impulse control issues, dizziness, constipation, nausea, hallucinations, and insomnia. References "Product Information.
