NCIt definition : An angiotensin-converting enzyme (ACE) inhibitor with antihypertensive activity. As
a prodrug, imidapril is converted by hydrolysis in the liver into its active form
imidaprilat. Imidaprilat 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. Imidaprilat also decreases
angiotensin II-induced aldosterone secretion by the adrenal cortex, which leads to
an increase in sodium excretion and subsequently increases water outflow.;
