Approved Drug Products with Therapeutic Equivalence Evaluations (Orange Book)
Did you ever wonder how the Orange Book got its nickname?
When the first print edition of Approved Drug Products with Therapeutic Equivalence Evaluations was being prepared October 1980, staff members in the Office of Generic Drugs had to choose a color for the cover. The project manager suggested, "It's almost Halloween. How about orange?"
Before long, The Orange Book had become a popular short title for this important publication.
About the Orange Book
The publication Approved Drug Products with Therapeutic Equivalence Evaluations (the List, commonly known as the Orange Book) identifies drug products approved on the basis of safety and effectiveness by the Food and Drug Administration (FDA) under the Federal Food, Drug, and Cosmetic Act (the Act). (For more information, see the Orange Book Preface.)
The Approved Drug Products list first appeared as a print publication in 1980. With the 25th edition (2005), Portable Document Format (PDF) versions of the Annual Edition and the Cumulative Supplement became available.
The Orange Book Search was added to the FDA website October 31, 1997.
