*Federal Register* Final rule: FDA is amending the animal drug regulations to reflect application-related actions for NADAs and ANADAs during March and April. These are Elanco Animal Health’s Imprestor, Aratana Therapeutics’ Galliprant, and Eco’s Aivlosin mediated article. The agency is also informing the public of the availability of summaries of the basis of approval and of environmental review documents, where applicable. The animal drug regulations are also being amended to reflect changes of sponsorship of applications and the voluntary withdrawals of approval of applications that occurred in January and February.
