Summary The antihypertensive and hormonal effects of the new angiotensin-converting enzyme (ACE) inhibitor, ramipril, were assessed by means of a single-blind trial in ten unselected patients with mild-to-moderate essential hypertension. After a 2-week period on placebo, 5 mg ramipril was administered once daily for 2 weeks. Blood pressure returned to normal in five patients and decreased in the remaining patients, without significant changes in heart rate or orthostatic hypotension. A fall in blood pressure was apparent within 1–2 h of the first dose; the maximum decrease was reached at 4–6 h and a fall in pressure was still detectable after 24 h. At 24 h post dose angiotensin-converting enzyme activity was suppressed to 40% of the baseline. Blood pressures for the 10 h interval post dosing showed smooth through-the-day control with minimal peak/trough difference in lowering effect. The magnitude of the blood pressure decrement achieved with the inhibitor did not correlate with baseline renin levels or the rise in renin following treatment. No side-effects were noted during the 2-week observation period. The study demonstrates that ramipril, given in a once-daily regimen over a period of 2 weeks, is well tolerated and provides smooth and effective blood pressure control throughout the 24-h interval between doses.
