NCIt definition : A sulfhydryl angiotensin-converting enzyme (ACE) inhibitor with antihypertensive activity.
As a prodrug, zofenopril is hydrolyzed in vivo into its active form zofenoprilat.
Zofenoprilat 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. Zofenoprilat also decreases angiotensin
II-induced aldosterone secretion by the adrenal cortex, which leads to an increase
in sodium excretion and subsequently increases water outflow.;
