Drug Prefixes and Suffixes by Class 

The is the common medication prefixes and suffixes list, some might call it drug prefixes roots and suffixes or pharmacology suffixes. There are about 800 of them, but I’ve put the most common ones by alphabetically by physiologic classification that I explain in detail in the Memorizing Pharmacology book. So whether you’re studying medication prefixes and suffixes for NCLEX®, NAPLEX®, USMLE® Step-1, PANCE® or whatever, knowing these will help you expand the number of drugs you’ll know on the exam very quickly.
