Which suffix is common to beta blockers?

• A. -lol
• B. -pril
• C. -sartan
• D. -ose

Answer: (A)

Beta blockers are commonly identified by the suffix that ends many of their drug names, which helps signal their class at a glance. The ending -lol appears in well-known examples such as propranolol, metoprolol, atenolol, and nadolol, confirming they block beta-adrenergic receptors. Other endings point to different drug classes: -pril is used for ACE inhibitors, -sartan for ARBs, and -ose is associated with sugars, not anti-hypertensive agents. Because the -lol ending directly flags beta-blocker medications, it’s the best indicator among the options.
