(verify) mechanism delapril is a prodrug; it is converted into two active metabolites, 5-hydroxy delapril diacid and delapril diacid. these metabolites bind completely to and inhibit angiotensin-converting enzyme (ace), hence blocking angiotensin i to angiotensin ii conversion. the resulting vasodilation prevents the vasoconstrictive effects of angiotensin ii. angiotensin ii-induced aldosterone secretion by the adrenal cortex is also decreased by delapril, leading to increases in excretion of sodium and therefore increases water outflow.
