II. Change of Sponsorship
Huvepharma EOOD, 5th Floor, 3A Nikolay Haytov Str., 1113 Sofia, Bulgaria, has informed FDA that it has transferred ownership of, and all rights and interest in, the following applications to Elanco US Inc., 2500 Innovation Way, Greenfield, IN 46140.
| File No. | Product name | 21 CFR section |
|---|---|---|
| 140-951 | CLINACOX (diclazuril) Type A Medicated Article | 558.198 |
| 141-153 | CLINACOX (diclazuril)/BMD (bacitracin methylenedisalicylate) | 558.198 |

As provided in the regulatory text of this document, the animal drug regulations are amended to reflect these changes of sponsorship.
III. Technical Amendments
We are reformatting the regulations in subpart B of part 558 for certain medicated feeds to present their approved conditions of use in the current tabular format. In addition, we are removing cross-referencing citations for indications for use of combination drug medicated feeds wherever they have been used and in their place are adding the full text of the indications. These actions are being taken to improve the consistency and readability of the regulations.
IV. Legal Authority
This final rule is issued under section 512(i) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 360b(i)), which requires Federal Register publication of “notice[s] . . . effective as a regulation,” of the conditions of use of approved new animal drugs. This rule sets forth technical amendments to the regulations to codify recent actions on approved new animal drug applications and corrections to improve the accuracy of the regulations, and as such does not impose any burden on regulated entities.
Although denominated a rule pursuant to the FD&C Act, this document 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. Likewise, this is not a rule subject to Executive Order 12866, which defines a rule as “an agency statement of general applicability and future effect, which the agency intends to have the force and effect of law, that is designed to implement, interpret, or prescribe law or policy or to describe the procedure or practice requirements of an agency.”

(2) Dichlorvos is a cholinesterase inhibitor. Do not use this product in animals simultaneously or within a few days before or after treatment with or exposure to cholinesterase-inhibiting drugs, pesticides, or chemicals. If human or animal poisoning should occur, immediately consult a physician or a veterinarian. Atropine is antidotal.
(3) Labeling for Type A articles and Type B feeds must include a statement that containers or materials used in packaging such Type A articles and Type B feeds are not to be reused and all such packaging materials must be destroyed after the product has been used.
