How ZESTRIL Works

Lisinopril inhibits angiotensin-converting enzyme (ACE), which catalyzes the conversion of angiotensin I to the potent vasoconstrictor angiotensin II. By suppressing the renin-angiotensin-aldosterone system, it decreases vasopressor activity and reduces aldosterone secretion. This results in systemic vasodilation and decreased blood pressure. Additionally, ACE inhibition prevents the degradation of the vasodilator bradykinin.
