Abstract

The kinetics of blood pressure changes and plasma angiotensin converting enzyme (ACE) inhibition in response to ramipril (HOE 498), 10 mg orally, were studied in 6 nephrectomized subjects 12 hours after ultrafiltration and in 10 patients with essential hypertension. Ramipril lowered supine and standing blood pressure in both groups, but the effect was greater in essential hypertension. The maximal blood pressure response followed the effect on plasma ACE after a lag time of 3 to 4 hours in both groups. These data provide indirect evidence that ramipril lowers blood pressure, at least in part, independently of its effect on the circulating renin-angiotensin system, possibly by acting on tissue ACE.
