In the same medication list, which drug is a beta-blocker?

• A. Amlodipine
• B. Bisoprolol
• C. Indapamide
• D. Ramipril

Answer: (B)

Identify which drug is a beta-blocker. Beta-blockers work by blocking beta-adrenergic receptors in the heart, which lowers heart rate, reduces contractility, and decreases overall cardiac output and blood pressure. Bisoprolol is selective for beta-1 receptors, making it cardioselective and commonly used for hypertension and heart-related conditions. The other drugs belong to different classes: amlodipine is a calcium channel blocker that causes vasodilation by inhibiting L-type calcium channels in vascular smooth muscle; indapamide is a thiazide-like diuretic that lowers blood pressure by increasing sodium and water excretion; ramipril is an ACE inhibitor that reduces angiotensin II formation, leading to vasodilation and decreased aldosterone. So, the beta-blocker in the list is bisoprolol.
