The FDA defines a generic drug as a medication created to be the same as an already marketed brand-name drug in dosage form, safety, strength, route of administration, quality, performance characteristics, and intended use. These similarities help to demonstrate bioequivalence, which means that a generic medicine works in the same way and provides the same clinical benefit as its brand-name version.¹

Many exploring generic pet medication options have questions about generics as a category and wonder about generic pet medication safety. Some questions include “are animal generics safe?” or “how does the FDA approve generic veterinary drugs?” In short, generics are safe and effective options made by different manufacturers than the pioneer(s) and approved by the FDA.

Yes. To gain FDA approval, the generic manufacturer must prove their product: 

• contains the same active ingredients as the brand
• is identical in strength, dosage form, and route of administration
• has the same indication as the brand
• is bioequivalent to the brand
• meets the same batch requirements for identity, strength, purity, and quality as the brand
• is manufactured under the same standards of good manufacturing practice regulations that the FDA requires for brand products.²

The Abbreviated New Animal Drug Application (ANADA) is the process used to approve the generic versions of animal pharmaceuticals that have already been proven safe and effective.³ 

The ANADA is called “abbreviated” because fewer steps are needed to bring a generic to market vs. a pioneer drug. For instance, the generic drug makers don’t need to repeat all the safety and effectiveness studies—the work has already been done for the pioneer product. To meet approval, the generic drug must have the same active ingredient, strength, dosage form, and administration method as the approved pioneer drug.³
