Drug Classes — Free AANP Reference
On the AANP exam, drug-class questions cluster around mechanism, contraindications, and the two or three board-favorite adverse effects. We built this reference for the night before the exam: every class on one page, no signup wall, no “14-day trial to see the rest.”
How to use it:search or scroll the categories below. Each class links to a detail page with mechanism, board pearls, contraindications, and a sample AANP-style question. When you’re ready to practice in question form, the full NPBoardSlay question bank has 1,500+ AANP-style questions with rationales — free trial, no card.
