The Orange Book is a reference for what relationship between drugs?

The Orange Book, officially known as the "Approved Drug Products with Therapeutic Equivalence Evaluations," serves as a resource for determining the therapeutic equivalence of drug products. It provides crucial information on which generic and brand-name drugs can be considered interchangeable based on their formulation, strength, dosage form, and route of administration. The therapeutic equivalence evaluations are vital for pharmacists and healthcare professionals in ensuring that patients receive safe and effective medication substitutions.

The correct answer highlights the role of the Orange Book in identifying drug products that are therapeutically equivalent, facilitating the safe use of generic alternatives to brand-name medications. This is essential for patient care, allowing for cost-effective treatment options without compromising quality.
