Alpha-1 blockers share which suffix?

Alpha-1 blockers share which suffix?

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

Answer: (A)

Suffixes in drug names often hint at the class of the medication. Alpha-1 blockers all end with -osin, so this ending identifies the group. Examples include prazosin, doxazosin, and terazosin. These drugs work by blocking alpha-1 adrenergic receptors, which leads to relaxation of vascular smooth muscle (lowering blood pressure) and, in the urinary tract, relaxation of the bladder neck to improve urine flow in BPH. The other suffixes correspond to different drug families: -pril indicates ACE inhibitors, -sartan indicates ARBs, and -vir typically signals antiviral agents.
