Which color-coded book can help identify FDA-approved medications that are bioequivalent and substitutable for a brand-name drug?

• A. Green
• B. Pink
• C. Orange
• D. Navy

Answer: (C)

Think of the essential resource as the FDA’s official guide to whether a generic can stand in for a brand-name drug. The Orange Book is titled Officially Approved Drug Products with Therapeutic Equivalence Evaluations, and it lists approved drugs and marks which ones are bioequivalent and interchangeable with brand-name versions. When a generic carries an AB rating in this book, it means it’s therapeutically equivalent to the brand-name product and can be substituted by a pharmacist. That makes the Orange Book the go-to reference for identifying substitutable, bioequivalent medications. Other color-coded volumes exist for different FDA information, but they don’t serve this specific purpose.
