## Abstract

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of a supplemental new animal drug application (NADA) filed by Elanco Animal Health, A Division of Eli Lilly & Co. The supplemental NADA for veterinary prescription use of tilmicosin Type C medicated swine feeds under a veterinary feed directive (VFD) provides a revised limitation to prevent accidental access by horses. Also, FDA amends the regulation to provide a swine muscle tolerance and an acceptable daily intake (ADI).
