Evaluation of amlodipine in mild to moderate hypertension--a clinical report.

Twenty two patients having mild to moderate hypertension were treated with a single daily dose of amlodipine for 4 weeks. Satisfactory response defined as final diastolic blood pressure < 90 mm of Hg and a reduction from baseline values > 10 mm of Hg could be achieved in 81.8% of patients in supine position and 70% of patients in standing position. Thirteen patients responded to 5 mg dose and 9 patients required 10 mg. Postural hypotension and reflex tachycardia were absent. Three patients has mild leg cramps and constipation. No deleterious effects were observed on liver, kidney and hemopoetic function, or on E.C.G. Changes. Amlodipine given once daily is effective and safe, and is a useful addition to the existing armamentarium of antihypertensive drugs.
