NCIt definition : A hydroxamic, non-amino acid derivative angiotensin-converting enzyme (ACE) inhibitor
with antihypertensive activity. Idrapril competitively binds to and inhibits ACE,
thereby blocking the conversion of angiotensin I to angiotensin II. This prevents
the potent vasoconstrictive actions of angiotensin II and results in vasodilation.
Idrapril also decreases angiotensin II-induced aldosterone secretion by the adrenal
cortex, which leads to an increase in sodium excretion and subsequently increases
water outflow.;
