What does pharmaceutically equivalent mean in FDA's therapeutically equivalent criteria?

• A. Same therapeutic outcome
• B. Same brand name
• C. Same dose, strength, dosage form, and administration route
• D. Same manufacturing facility

Answer: (C)

Pharmaceutically equivalent means the two drug products contain the same active ingredient in the same dose, in the same dosage form, and by the same route of administration. In other words, they deliver the same amount of drug the same way, so from a chemical and product-identity standpoint they are interchangeable, even if their inactive ingredients differ. This focuses on the physical characteristics of the product rather than the clinical effect. For true interchangeability in therapy, the products also need to be bioequivalent, meaning they release the drug into the body at a similar rate and extent. The other ideas—that they must produce identical therapeutic outcomes, share a brand name, or come from the same manufacturing facility—do not define pharmaceutically equivalent.
