NCIt definition : A prodrug and nonsulfhydryl angiotensin converting enzyme (ACE) inhibitor with antihypertensive
activity. Ramipril is converted in the liver by de-esterification into its active
form ramiprilat, which inhibits ACE, thereby blocking the conversion of angiotensin
I to angiotensin II. This abolishes the potent vasoconstrictive actions of angiotensin
II and leads to vasodilatation. This agent also causes an increase in bradykinin levels
and a decrease in angiotensin II-induced aldosterone secretion by the adrenal cortex,
thereby promoting diuresis and natriuresis.;
