About this test
Brand/generic fluency for the most-dispensed drugs is the highest-yield memorization work in PTCE prep: these are the medications your Medications-domain questions (35% of the exam) draw from, and the ones you'll handle every shift once certified.
This quiz covers a deliberate spread across the classes that dominate US dispensing: statins, ACE inhibitors and ARBs, beta blockers, PPIs, SSRIs and SNRIs, antibiotics, antidiabetics, thyroid replacement, anticoagulants, and inhalers.

Key concepts to know
Learn by suffix families
Generic-name suffixes encode the class: -statin (HMG-CoA reductase inhibitors), -pril (ACE inhibitors), -sartan (ARBs), -olol (beta blockers), -prazole (PPIs), -floxacin (fluoroquinolones). Suffix recognition rescues you when a specific drug is unfamiliar.
Pair drug with indication
The exam rarely asks names in isolation; it asks what the drug treats. Always learn the triple: brand, generic, and primary indication (metformin/Glucophage → type 2 diabetes).
Top 200 Drugs Quiz: FAQ
Do I need to memorize all 200 drugs for the PTCE?
No exam requires all 200 verbatim, but the most-dispensed drugs appear constantly in Medications-domain questions. Prioritize the top 100 by prescription volume and the suffix patterns that identify classes.
Where does the top 200 list come from?
Rankings of US prescription volume, such as ClinCalc DrugStats, which aggregates national dispensing data. The list shifts slightly year to year, but the leaders (atorvastatin, levothyroxine, lisinopril, metformin) are stable.
