Which statement accurately describes generic drug equivalence?

• A. It must be identical in dosage form, strength, route of administration, and quality with identical performance characteristics.
• B. It must have a different active ingredient but same therapeutic effect.
• C. It must be produced by the same manufacturer.
• D. It must be used for a different indication.

Answer: (A)

Generic drug equivalence means a generic product must be therapeutically equivalent to the brand-name drug, delivering the same active ingredient in the same dosage form and strength, by the same route, and meeting the same quality standards so its pharmacokinetic profile is the same enough to produce the same safety and efficacy. The statement that describes identical dosage form, strength, route of administration, and quality with identical performance characteristics best captures these requirements, because it implies both the same active ingredient (through the same dosage form and strength) and the same bioequivalence/therapeutic effect. This is why a generic should not differ in active ingredient, should not be tied to the same manufacturer as a requirement, and should not be used for a different indication.
