Common questions
How many medication questions are on the PTCB exam?
Medications is the largest domain: 35% of the exam, about 28 of the 80 scored questions. It spans brand↔generic mapping, classes, interactions, side effects, stability, and storage — not just top-200 recall.
Do I need to know brand AND generic names?
Yes — both directions. The exam asks “what is the generic for X?” and the reverse, and interaction questions often name one drug by brand and the other by generic. Study from the top-200 table with both columns visible, then quiz here.
Are drug interactions on the PTCE?
Yes — common or life-threatening interactions and contraindications are a named knowledge area. Expect the famous pairs: warfarin with NSAIDs, opioids with benzodiazepines, nitrates with PDE-5 inhibitors, and statins with strong CYP3A4 inhibitors. Rationales here teach the mechanism so the pattern generalizes.
What's the fastest way to memorize the top 200 drugs?
Learn suffix patterns first — one suffix unlocks a whole class (the table below), which covers a large share of the list. Then drill the exceptions in short daily sessions and let the weak-area report tell you which classes still miss.
