Which suffix indicates a beta-blocker, relevant to cardiovascular therapy?

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

Answer: (A)

The main idea here is recognizing how drug names point to a class and its mechanism. Beta-blockers work by blocking beta-adrenergic receptors, which slows the heart, decreases force of contraction, and lowers blood pressure—useful for hypertension, angina, and certain arrhythmias. The term betablocker explicitly names this class, making it the best cue among the options. The other terms refer to different cardiovascular drug classes (calcium channel blockers, ACE inhibitors, diuretics) and do not indicate beta-adrenergic blockade.
