What does the FDA Orange Book AB rating mean?

• A. The drug is not therapeutically equivalent to any pharmaceutically equivalent products
• B. The drug is currently being evaluated for bioequivalence
• C. Actual or potential bioequivalence problems have been resolved and a drug is considered therapeutically equivalent to other pharmaceutically equivalent products
• D. The drug is a biological product

Answer: (C)

In the FDA Orange Book, an AB designation means that any actual or potential bioequivalence problems have been resolved and the drug is therapeutically equivalent to other pharmaceutically equivalent products. This indicates the product has demonstrated bioequivalence to the reference product, so it should have the same clinical effect and safety profile when used under the same conditions. This is what justifies substituting a generic for the brand-name product, subject to applicable laws in a given jurisdiction. The other statements do not fit because this rating is specifically about confirmed bioequivalence and therapeutic equivalence, not about ongoing evaluation, nor about being a biological product.
