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 Pharmgate LLC for the use of a Type A medicated article containing bacitracin methylenedisalicylate to manufacture Type B and Type C medicated feeds for chickens, turkeys, pheasants, quail, and feedlot cattle.

For cattle, the approval specifies use for preventing liver abscesses.  

This supplemental approval reflects FDA's effectiveness conclusions that relied on the National Academy of Sciences/National Research Council Drug Efficacy Study Group's evaluation of the effectiveness of this drug as well indications for use not subject to this review.
