CYP3A4 Inhibitors Co-administration of a 180 mg daily dose of diltiazem with 5 mg amlodipine in elderly hypertensive patients resulted in a 60% increase in amlodipine systemic exposure.

However, strong inhibitors of CYP3A4 (e.g., ketoconazole, itraconazole, ritonavir) may increase the plasma concentrations of amlodipine to a greater extent.

Monitor for symptoms of hypotension and edema when amlodipine is co-administered with CYP3A4 inhibitors.

Calcium Channel Blockers: e.g., amlodipine diltiazem felodipine nicardipine nifedipine verapamil ↑ calcium channel blockers Caution is warranted and clinical monitoring is recommended upon coadministration of calcium channel blockers with GENVOYA.
