Classification based on therapeutic potential is called what?

• A. Functional Classification
• B. Therapeutic Index
• C. Pharmacologic Classification
• D. Letter Classification

Answer: (D)

The main idea is grouping drugs by what they’re used to treat—their therapeutic use. This is therapeutic classification: drugs are categorized based on the clinical condition they aim to improve or the therapeutic outcome they provide. It helps clinicians pick medications that address a specific problem (for example, medications used for hypertension, pain, or infection) rather than focusing on how the drug works at a molecular level.

This classification contrasts with pharmacologic classification, which groups drugs by mechanism of action or receptor targets, and with broader functional labeling that isn’t a standard way to organize drugs by therapeutic purpose. A “letter” scheme isn’t a recognized pharmacology framework, so it isn’t a valid basis for classification by therapeutic potential. The concept being tested is understanding drugs by their therapeutic use, i.e., therapeutic classification.
