FDA Inspection Manual on Veterinary Drug Activities With Number to Report Violations

5.9.2 - VETERINARY DRUG ACTIVITIES

CVM is responsible for inspections of therapeutic and production drugs, and Active Pharmaceutical Ingredients (APIs). Therapeutic drugs are used in the diagnosis, cure, mitigation, treatment or prevention of disease. Production drugs are used for economic enhancement of animal productivity. Examples include: growth promotion, feed efficiency and increased milk production.
Preapproval inspections are conducted pursuant to pending NADA or ANADA applications.

Post approval inspections of veterinary drugs are conducted to determine compliance with the Current Good Manufacturing Practices (CGMPs) for Finished Pharmaceuticals under 21 CFR Part 211³. These cGMPs apply to both human and veterinary drugs. Information on veterinary drugs approved can be found in the "Green Book" database accessed through CVM's website.

APIs are active pharmaceutical ingredients. Many of the APIs used to manufacture dosage form drugs are imported from foreign countries. The intended source for an API must be indicated in NADA/ANADA submissions for new animal drug approvals. Any change in a source for an API would require a supplement to the application.

Extra label drug use refers to the regulations in 21 CFR Part 530⁴ codified as a result of the Animal Medicinal Drug Use Clarification Act⁵ (AMDUCA) of 1994. These regulations set forth the requirements that veterinarians must meet to prescribe extra label uses of FDA approved animal and human drugs. The regulations describe what is a valid veterinary-client-patient relationship as well as what is considered illegal extra label use. 21 CFR Part 530 addresses issues regarding extra label use in non-food as well as food producing animals. 21 CFR 530.41⁶ contains a list of drugs that cannot be used in an extra label manner in food-producing animals. During an inspection or investigation if you encounter any situations on suspected illegal extra label use of any FDA approved animal or human drugs or those prohibited for extra label use in food animals, you should contact CVM's Division of Compliance (HFV-230) (240-276-9200).

21 CFR Part 530 also addresses compounding of products from approved animal or human drugs by a pharmacist or veterinarian. The regulations clearly state compounding is not permitted from bulk drugs. This would include APIs. CVM has an existing CPG on Compounding of Drugs for Use in Animals (CPG 608.400⁷). A copy can be found on CVM's website. The Division of Compliance (HFV-230) has issued assignments to conduct inspections of firms, including internet pharmacies, who may be engaged in the practice of manufacturing under the guise of pharmacy compounding. You should contact the Division of Compliance (HFV-230) at 240-276-9200 to report instances of compounding or to seek guidance on inspectional issues, or regulatory and enforcement policies.
