New Animal Drug Application
New Animal Drug Application (NADA) is the FDA process to approve drugs used in animals in the United States. It is defined in 21 CFR 514, after the definition of a New Animal Drug in 21 CFR 510. A new animal drug is any drug meant for animals (not humans), including drugs used in animal feed but not the feed itself, whose safety and effectiveness must be proven for its labeled use. The NADA system comes from the Federal Food, Drug, and Cosmetic Act, as amended by the FDA Amendments Act of 2007, on September 27, 2007. NADA is the animal-drug counterpart to the human New Drug Application. There are three types of new animal drug applications.
