NAPLEX Practice Exam 2026 – Comprehensive Test Preparation

Question: 1 / 1820

What does the Orange Book (FDA) list?

Approved drugs that can be interchanged with generics

The Orange Book, published by the FDA, lists approved drugs that can be interchanged with generics. This book provides information about drug products approved on the basis of safety and effectiveness by the FDA. It includes therapeutic equivalence evaluations, which are used by healthcare professionals to determine whether one drug product can be substituted for another. Therefore, option A is correct.

Biological drug products are usually listed in the Purple Book, not the Orange Book. Drug pricing information is typically not included in the Orange Book, and regulatory and business development references are also not the main focus of the Orange Book.
