Compounding: Understanding FDA final guidance #256

Animal drugs compounded from bulk drug substances aren’t approved by the U.S. Food and Drug Administration (FDA). However, the FDA recognizes that compounded drugs can serve an important medical need for animal patients when no FDA-approved or indexed drug is available. In November 2019, FDA’s Center for Veterinary Medicine issued new guidance for animal drug compounding: Guidance for Industry (GFI) #256, Compounding Animal Drugs from Bulk Drug Substances. Join FDA veterinarian Dr. Amber McCoig for an overview of the final guidance and the policies that impact veterinarians and our teams. 

Participants can expect to learn:

  • Why the FDA cannot assure the safety, effectiveness, or quality of bulk drug substances 
  • How the FDA’s final guidance tries to balance the risks of animal drugs compounded from bulk substances when no FDA-approved drug is available for treatment
  • Policies included in the final guidance and how they impact veterinary practice
