What is the mechanism of action of lisinopril?
Show answer and explanation
Correct answer: A. ACE inhibitor
Lisinopril is an ACE (angiotensin-converting enzyme) inhibitor, blocking the conversion of angiotensin I to angiotensin II — reducing angiotensin II-mediated vasoconstriction and aldosterone-driven sodium/water retention, thereby lowering blood pressure.
