Understanding drug names and their classifications is crucial for healthcare professionals and nursing students. These Drug Suffix Lists are a handy resource designed to help you quickly recognize the purpose and category of medications based on their suffixes (or stems). Whether you’re studying pharmacology, preparing for exams, or managing a busy workload in a clinical setting, these lists will simplify the learning and recall process.
Each printable table is organized by the suffix, class, explanation, and example drugs. For instance, if you see a drug ending in -afil (like sildenafil), you’ll know it’s an inhibitor of PDE5 with vasodilator action. This structure makes it easier to connect a drug’s name to its action and category, streamlining your workflow and helping you provide better patient care.
Our drug stem cheat sheets are an invaluable tool for learning medication classifications and their uses, and they go great with these Pharmacology Study Sheets. To complement this resource, pair it with our Nurse Skills Template to develop clinical proficiency, Nursing Clinical Template for practical applications and Disease Templates for more study resources.

Frequently Asked Questions
What are the most common drug suffixes nursing students need to know?
The most essential drug suffixes for nursing students include -olol (beta blockers like metoprolol), -pril (ACE inhibitors like lisinopril), -statin (cholesterol drugs like atorvastatin), -azole (antifungals like fluconazole), -cillin (penicillin antibiotics like amoxicillin), and -pam/-lam (benzodiazepines like lorazepam and diazepam). Knowing these suffixes helps you quickly identify a drug’s class, mechanism of action, and potential side effects during clinical rotations. Our free printable drug suffix list covers over 50 common suffixes organized by drug class with examples and key nursing considerations for each.
How do drug suffixes help you identify medication classes?
Drug suffixes are standardized name endings assigned by the United States Adopted Names (USAN) Council to group medications by their pharmacological class. When you see a drug ending in -sartan, you immediately know it is an angiotensin II receptor blocker (ARB) used for blood pressure. This classification system means you do not need to memorize every individual drug name. Instead, learning approximately 30-50 key suffixes lets you quickly identify the drug class, expected therapeutic effects, common side effects, and nursing interventions for hundreds of medications.
What is the best way to memorize drug suffixes for pharmacology?
The most effective approach is to study drug suffixes by class rather than alphabetically. Group related suffixes together: for example, learn all blood pressure medication suffixes (-olol, -pril, -sartan, -dipine) as a set. Create flashcards with the suffix on one side and the drug class, an example drug, and one key nursing consideration on the other. Practice with our free printable drug suffix cheat sheet by covering the drug class column and testing yourself on each suffix. Spaced repetition, reviewing daily for the first week then every few days, produces the best long-term retention for pharmacology exams.
What is the difference between a drug prefix and a drug suffix?
A drug suffix is the ending of a generic drug name that identifies its pharmacological class, such as -statin for cholesterol-lowering drugs. A drug prefix or stem at the beginning of a drug name often identifies a specific sub-class or generation within that larger class. For example, within the -cillin suffix family, “amox-” identifies amoxicillin as a specific aminopenicillin. Suffixes are generally more useful for nursing students because they allow you to categorize any unfamiliar drug into its class instantly. Our free printable reference sheet focuses primarily on suffixes but also includes common prefixes for the most frequently prescribed drug families.
