Clinical trial of benidipine in mild to moderate hypertension.

ABSTRACT

Thirty four patients with mild to moderate hypertension, were put on benidipine 4 mg/day after two weeks of placebo therapy. Twenty five patients completed the trial successfully for 4 mg benidipine. The blood pressure of 20 patients was controlled with benidipine 4 mg/day (effective rate 80%). Five patients with unsatisfactory control on 4 mg/day benidipine were put on 8 mg/day. Four of them were controlled and one was considered as failure (effective rate 80%). Most of the patients tolerated the drug well. Three patients had mild side effects like headache and heaviness in the head. One of them also had puffiness of face and body (on benidipine 8 mg/day) and was withdrawn from the study. One patient had mild constipation. We conclude that benidipine is well tolerated in the dose of 4-8 mg/day and is an effective antihypertensive agent for treatment of patients with mild to moderate hypertension.
