Beta-blockers commonly end with which suffix?

Beta-blockers commonly end with which suffix?

• A. -vir
• B. -osin
• C. -pril
• D. -olol

Answer: (D)

Suffix patterns in drug names help you identify their class. For beta-blockers, the common ending is -olol, as seen in propranolol, metoprolol, atenolol, and nadolol. This naming cue reflects their mechanism—blocking beta-adrenergic receptors—and aligns with their clinical uses, such as treating hypertension, angina, and certain arrhythmias. Other endings point to different drug groups: -vir for antivirals, -osin for alpha-adrenergic blockers, and -pril for ACE inhibitors. So the -olol ending is the best clue that a drug is a beta-blocker.
