Calcium channel blockers are commonly identified by which suffix in their generic names?

• A. Pine suffix
• B. Pril suffix
• C. Olol suffix
• D. Sartan suffix

Answer: (A)

Drug naming often uses suffixes to signal a drug class. Calcium channel blockers are commonly identified by the -pine ending in their generic names, especially the dihydropyridine subclass used for lowering blood pressure and treating angina (for example, amlodipine, nifedipine). That -pine pattern is a handy cue that many of these drugs share a mechanism—blocking calcium channels in vascular smooth muscle to promote vasodilation and reduce BP. There are exceptions, though. Not all calcium channel blockers end in -pine; non-dihydropyridines like verapamil and diltiazem follow different endings. The other suffixes listed point to completely different drug classes: -pril indicates ACE inhibitors, -olol indicates beta blockers, and -sartan indicates ARBs.
