Hong KongIndications
An indication is the condition a drug is used to treat.
- Learning one indication per therapeutic class covers this knowledge area efficiently.

A knowledge area that is nearly free if you learned classes properly, and a large task if you did not.
The definition
The condition or purpose for which a drug is used. Approved indications appear in the labeling, which is governed by 21 CFR Part 201. Attach it to the class.
Why the class does the work
Indications largely run by therapeutic class. A class treating hypertension treats hypertension whichever member you are looking at.
So one indication attached to each class covers every member, which is the efficient structure.
Some classes are used for more than one condition, and some individual drugs have an indication their class does not. Those are the ones worth noting specifically, because a question exploiting them is testing whether you learned the class or the drug.
Off-label use
A drug prescribed for something other than an approved indication. It is lawful and common, and it is not a technician's decision to question. Lawful and common.
A question presenting an unusual indication may be testing whether you know that, rather than whether you know the drug.
Where indications appear on the exam
Directly, as what a drug treats. And indirectly, inside duplication questions - two drugs sharing an indication is often what makes them a duplication. Never learn it twice.
How to study it
Not separately. Attach the indication when you learn the class, along with the stem, some members and a common adverse effect.
Studying indications as their own list means learning the same information twice.
