Abstract

Twenty patients with acute severe hypertension were randomised to therapy with either nifedipine capsules (10 mg) or captopril tablets (25 mg) given sublingually and the blood pressure recorded for 240 minutes. Oral monotherapy with either agent followed for 3 weeks, then the agents were combined for a further 2 weeks and in the final 6 weeks of the trial a beta-blocker and diuretic were added, if needed. Thirteen patients completed the trial. The major results were: (i) nifedipine decreased blood pressure more rapidly than captopril 60 minutes after first ingestion but at 240 minutes equal degrees of fall in blood pressure had been obtained; (ii) neither agent given as sustained monotherapy was able to reduce blood pressure adequately, although nifedipine was better than captopril; and (iii) combination therapy with both agents was conspicuously successful in achieving reduction in blood pressure. It is suggested that combination nifedipine-captopril therapy be subject to a formal trial for early therapy in acute severe hypertension.
