Hong KongMedications domain
Medications is 35 percent of the paper, 28 of the 80 scored questions, across six knowledge areas. Learning drugs by class serves four of the six; a flat name list serves one.
The largest domain, and the one where preparation is most often shaped by the wrong assumption about what it asks.
The six knowledge areas
- Generic names, brand names and classifications
- Therapeutic duplications and drug interactions
- Strengths, dosage forms, routes and duration of therapy
- Side effects, adverse effects and allergies
- Indications of medications
- Drug stability and proper storage
Two of them carry more weight in the outline than the others: duplications and interactions, and stability and storage.
Most preparation treats this domain as name recall, which is area one. Duplications and interactions require you to reason across drugs, and stability and storage is a separate, finite, entirely learnable block. Both carry more weight than the naming area, and both are usually under-prepared.
How to learn it
By therapeutic class, with an indication and a common adverse effect attached to each. That single structure serves areas one, two, four and five. Spacing beats intensity.
Storage gets its own session. Dosage forms and routes are largely definitional.
What changed in 2026
It shrank, from 40 percent to 35, which is 32 scored questions to 28. Still the biggest domain, and no longer more than three times the size of Federal Requirements. Twenty-eight of eighty.
A study plan inherited from the old paper over-invests here by about a third.
How much time it deserves
Roughly a third of your hours, matching 28 of 80, and started early because memorization settles with spacing rather than with intensity.
When you have done enough
When you can place an unfamiliar generic name into a plausible class from its stem, and attach an indication to it. That is the skill the domain rewards. Storage gets its own session.
