Food and Drug Administration, HHS.
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 provides for use of tilmicosin Type C medicated feeds by veterinary feed directive for the control of bovine respiratory disease in groups of beef and nonlactating dairy cattle.
This rule is effective December 9, 2011.

Elanco Animal Health, a division of Eli Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filed a supplement to NADA 141-064 for PULMOTIL 90 (tilmicosin phosphate) Type A medicated article. The supplemental NADA provides for the use of tilmicosin Type C medicated feeds by veterinary feed directive for the control of bovine respiratory disease (BRD) associated with Mannheimia haemolytica, Pasteurella multocida, and Histophilus somni in groups of beef and nonlactating dairy cattle where active BRD has been diagnosed in at least 10 percent of the animals in the group. The supplemental NADA is approved as of August 19, 2011, and 21 CFR 558.4 and 558.618 are amended to reflect the approval.
In accordance with the freedom of information provisions of 21 CFR part 20 and 21 CFR 514.11(e)(2)(ii), a summary of safety and effectiveness data and information submitted to support approval of this application may be seen in the Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, Rockville, MD 20852, between 9 a.m. and 4 p.m., Monday through Friday.
Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), this supplemental approval qualifies for 3 years of marketing exclusivity beginning on the date of approval.
The Agency has carefully considered the potential environmental impact of this action and has concluded that the action will not have a significant impact on the human environment and that an environmental impact statement is not required. FDA's finding of no significant impact and the evidence supporting that finding, contained in an environmental assessment, may be seen in the Division of Dockets Management (address above) between 9 a.m. and 4 p.m., Monday through Friday.
This rule does not meet the definition of “rule” in 5 U.S.C. 804(3)(A) because it is a rule of “particular applicability.” Therefore, it is not subject to the congressional review requirements in 5 U.S.C. 801-808.

(c) Special considerations—(1) Tilmicosin medicated feeds are restricted to use under a veterinary feed directive (VFD). See § 558.6 of this chapter for required label statements and other limitations.
(2) VFDs for tilmicosin phosphate shall not be refilled.
(3) Labeling of tilmicosin Type B or Type C medicated feeds must bear the following warnings:
(i) Do not allow horses or other equines access to feeds containing tilmicosin.
(ii) Use of antibacterial drugs in the absence of a susceptible bacterial infection is unlikely to provide benefit to treated animals and may increase the risk of the development of drug-resistant pathogenic bacteria.
(4) Special considerations for use of tilmicosin medicated swine feeds include the following:
(i) The expiration date of VFDs for tilmicosin must not exceed 90 days from the time of issuance.
(ii) Labeling of tilmicosin Type B or Type C medicated feeds for swine must bear the following warning: “Do not use in any feeds containing bentonite. Bentonite in feeds may affect the efficacy of tilmicosin.”
(iii) Feed containing tilmicosin shall not be fed to pigs for more than 21 days during each phase of production without ceasing administration for reevaluation of antimicrobial use by a licensed veterinarian before reinitiating a further course of therapy with an appropriate antimicrobial.
(5) Special consideration for use of tilmicosin medicated cattle feeds include the following:
(i) The expiration date of VFDs for cattle must not exceed 45 days from the time of issuance.
(ii) Labeling of tilmicosin Type B or Type C medicated feeds for cattle must bear the following warning: “Do not use in any feeds containing bentonite, cottonseed meal, or cottonseed hulls. Bentonite, cottonseed meal, or cottonseed hulls in feeds may affect the efficacy of tilmicosin.”
(iii) To assure both food safety and responsible use in cattle, administration of feed containing tilmicosin to cattle Start Printed Page 76895experiencing an outbreak of BRD must be initiated during the first 45 days of the production period, shall not exceed a single 14-consecutive-day treatment, should not occur concurrent with or following administration of an injectable macrolide, and should not occur within 3 days following administration of a nonmacrolide injectable BRD therapy. Tilmicosin medicated feed treatment has not been evaluated in cattle with severe clinical disease. Cattle with severe clinical illness should be evaluated for individual treatment with an alternative non-macrolide therapy.
