What type of medication is lisinopril?

• A. Beta blocker
• B. ACE inhibitor
• C. Calcium channel blocker
• D. Diuretic

Answer: (B)

Lisinopril is classified as an ACE inhibitor, which stands for Angiotensin-Converting Enzyme inhibitor. ACE inhibitors are primarily used to manage hypertension (high blood pressure) and heart failure by blocking the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. This action leads to relaxation of blood vessels, decreased blood volume, and overall reduction in blood pressure. Additionally, lisinopril offers protective effects on the kidneys, particularly for patients with diabetes or other conditions that increase the risk of renal impairment. Its role in reducing afterload in heart failure and providing cardiovascular protection makes it a critical medication in various treatment protocols. The other medication categories mentioned—beta blockers, calcium channel blockers, and diuretics—function differently. Beta blockers primarily reduce heart rate and force of contraction, calcium channel blockers decrease the contractility of the heart and dilate blood vessels, while diuretics increase urine output to reduce fluid overload. Each of these categories addresses specific cardiac or vascular issues but does not perform the same function as an ACE inhibitor, which is why lisinopril's classification as an ACE inhibitor is the most accurate.
