The term Pharm Eq represents which regulatory concept?

• A. Pharmaceutical Equivalence
• B. Therapeutic Equivalence
• C. Authorized Generic
• D. Biosimilar

Answer: (A)

Pharmaceutical equivalence means two drug products contain the same active ingredient in the same strength and dosage form, intended for the same route of administration, and meet the same quality standards. They may differ in inactive ingredients or packaging, but the key is that the active ingredient, amount, dosage form, and route are identical, so the products are expected to deliver the same medication dose in the body.

This is different from therapeutic equivalence, which adds that the products not only are pharmaceutically equivalent but also produce the same clinical effect and safety profile in patients, usually shown through bioequivalence data.

An authorized generic is a generic version produced by the brand’s own manufacturer and marketed under a different label, which is a separate concept. A biosimilar refers to a highly similar biologic product with no clinically meaningful differences from a reference biologic, and applies to complex biologics rather than small-molecule drugs.
