Alpha-1 blockers share which suffix?

Alpha-1 blockers share which suffix?

• A. -osin
• B. -pril
• C. -sartan
• D. -cycline

Answer: (A)

Recognizing drug groups by their suffix helps you quickly identify how a medication works. Alpha-1 blockers all share the suffix -osin, so drugs like prazosin, doxazosin, terazosin, and tamsulosin fit this group. Their action is to block alpha-1 adrenergic receptors on vascular smooth muscle, causing vasodilation and lower blood pressure. They also relax the smooth muscle in the bladder neck and prostate region, which helps improve urine flow in benign prostatic hyperplasia. Other suffixes point to different drug families: -pril indicates ACE inhibitors, -sartan indicates ARBs, and -cycline indicates tetracycline antibiotics. So the suffix shared by alpha-1 blockers is -osin.
