What does an FDA Orange Book 'A' rating mean?

• A. The drug is not therapeutically equivalent to other products
• B. The drug is considered therapeutically equivalent to other pharmaceutically equivalent products
• C. The drug is a biologic product
• D. The drug has no substitution rights

Answer: (B)

An FDA Orange Book rating labeled A means the product is therapeutically equivalent to other pharmaceutically equivalent products. This signifies that it contains the same active ingredient, strength, dosage form, and route of administration, and is expected to produce the same clinical effect and safety profile when used according to the labeling. Because of that, it is generally considered interchangeable with the reference product, subject to state laws and pharmacy policies about substitution. The rating does not relate to biologics (which are covered elsewhere) or to substitution rights by itself—those rights vary by jurisdiction and are not dictated by the Orange Book rating.
