Co-administration of CYP3A4 inhibitors eg, ketoconazole, itraconazole, erythromycin, grapefruit juice, cimetidine with felodipine may lead to several-fold increases in the plasma levels of felodipine, either due to an increase in bioavailability or due to a decrease in metabolism. These increases in concentration may lead to increased effects, lower blood pressure and increased heart rate. These effects have been observed with co-administration of itraconazole a potent CYP3A4 inhibitor. Caution should be used when CYP3A4 inhibitors are co-administered with felodipine.
