Which of the following is an ACE inhibitor?

Which of the following is an ACE inhibitor?

• A. Benazepril
• B. Irbesartan
• C. Metoprolol
• D. Amlodipine

Answer: (A)

ACE inhibitors work by blocking the enzyme that converts angiotensin I to angiotensin II, leading to vasodilation, reduced aldosterone, and lower blood pressure. Medications in this class typically end with the suffix -pril, so Benazepril is an ACE inhibitor. Irbesartan is an ARB, which blocks angiotensin II receptors rather than its production. Metoprolol is a beta-blocker, affecting heart rate and output, and Amlodipine is a calcium channel blocker that relaxes vascular smooth muscle. Thus, Benazepril is the ACE inhibitor among these options.
