A different dihydropyridine calcium channel blocker in hypertensive patients who developed pedal edema on dihydropyridine calcium channel blocker therapy

33376

Aim. Dihydropyridine calcium channel blockers (CCB) are widely preferred for the treatment of hypertension for their efficacy, metabolic neutrality and low side effect profile. However pedal edema formation limits their usage. The aim of the present study is to evaluate the incidence of pedal edema formation with a different dihydropyridine CCB in hypertensive patients who developed pedal edema during a dihydropyridine CCB therapy. Method. Fifty-eight hypertensive patients (34 female, 24 male, mean age: 65.3±10.5) in whom pedal edema developed during treatment with a dihydropyridine CCB (amlodipine 10mg/day in 40 patients, amlodipine 5mg/day in 14 patients, nifedipine GITS 30mg/day in 4 patients) were enrolled. CCB which caused pedal edema was withdrawn and a different CCB (felodipine or lacidipine) were initiated after the resolution of the pedal edema. CCB therapy was continued as long as the patient tolerated pedal edema. Results. At the end of one year, 44 out of 58 patients (36 [81.8%] free of pedal edema, 8 [19.2%] with pedal edema) continued CCB therapy. Eleven (37.9%) patients in the felodipine group and 9 (31.0%) patients in the lacidipine group developed pedal edema. In 7 patients in felodipine group and in 5 patients in the lacidipine group the study drug was withdrawn due to pedal edema. In two patients, study drug was withdrawn due to intractable headache (felodipine group) or due to flushing (lacidipine group). Conclusion. A different group of dihydropyridine CCB be used as an alternative therapy for hypertension whenever pedal edema develops during treatment with a dihydropyridine CCB.
