Choice of initial therapy for hypertension. JAMA. Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmHg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension for example, patients with diabetes or hyperlipidemia and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal.

CYP3A4 inhibitors: Potential for increased plasma felodipine concentrations, with possible reduction in BP and increase in heart rate; use with caution. Felodipine is metabolized by CYP3A4. 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. A conservative approach to dosing felodipine should be taken. High-fat or high-carbohydrate meal increases peak plasma concentrations but does not affect extent of absorption.
