The U.S. Food and Drug Administration is today announcing that five drug sponsors holding animal drug applications affected by Guidance For Industry (GFI) #213 have requested that FDA withdraw approval of a collective 19 animal drug applications because the products are no longer manufactured or marketed. Of these 19 applications, 16 are antimicrobials affected by GFI #213. The guidance outlines FDA’s plan to help curb antimicrobial resistance by, among other things, phasing out the use of medically important antimicrobials in food-producing animals for production purposes. A complete list of products and manufacturers is posted on the agency’s website. [Source: FDA-CVM News Release]
