Cilazapril is the monoethyl ester prodrug form of a potent, specific. long-acting antihypertensive inhibitor of angiotensin-converting enzyme (ACE). The biochemical and pharmacological properties of this compound have been compared with those of captopril and enalapril. In all test systems, cilazapril was the most potent and the longest acting. The active diacid of cilazapril was more potent than the corresponding diacid of enalapril in inhibiting the cleavage of angiotensin I and of Hip-His-Leu by ACE in vitro, in antagonising the angiotensin I-induced contractions of the isolated ileum of the guinea pig, in potentiating the vasodepressor responses to bradykinin, and in reducing the angiotensin I-induced rise in blood pressure of the rat. Parent drug absorption and diacid bioavailability in the rat were higher than for enalapril, and the inhibition of plasma ACE of longer duration. Single doses of cilazapril were more potent than enalapril in lowering the blood pressure of spontaneously hypertensive rats (SHR) and two-kidney renal hypertensive rats. On repeated daily oral dosing to SHR, both compounds had a cumulative antihypertensive effect. The acute antihypertensive effect was enhanced by simultaneous treatment with hydrochlorothiazide.
