II. Changes of Sponsorship

    Increvet, Inc., 200 Portland St., Floor 3, Boston, MA 02114 has 
informed FDA that it has transferred ownership of, and all rights and 
interest in, NADA 141-566 for BEXACAT (bexagliflozin tablets) Tablets, 
approved December 8, 2022, to Elanco US Inc., 2500 Innovation Way, 
Greenfield, IN 46140. The regulatory text for the original approval of 
this application reflects this change of sponsorship.

III. Technical Amendments

    FDA is making the following amendments to improve the accuracy of 
the animal drug regulations:
     21 CFR 516.498 is removed from subpart C of part 516 and 
is added to subpart E.
     21 CFR 520.370, 520.522, 522.246, 522.304, 522.2470, 
524.1044c, 524.1044f, and 524.1484g are amended to reflect a sponsor's 
current drug labeler code.
     21 CFR 520.441 is amended to revise the sponsor listings 
for uses of chlortetracycline in drinking water of various food-
producing animals.
     21 CFR 520.443 is amended to revise the sponsor listings 
for uses of chlortetracycline tablets and boluses in calves.
     21 CFR 520.1196 is amended to revise the indication for 
uses of ivermectin and pyrantel tablets in dogs.
     21 CFR 522. 1660a is amended to reflect the correct drug 
labeler code for a sponsor of an oxytetracycline injectable solution.
     21 CFR 522.2471 is amended to add human food safety 
warnings for use of tilmicosin injectable solution in cattle and sheep.
     21 CFR 524.1448 is amended to revise the indication for 
use of mirtazapine transdermal ointment in cats.
     21 CFR 556.222 is amended to reflect a revised tolerance 
for residues of doramectin in liver of cattle.
     21 CFR 556.500 is amended to reflect revised numbering of 
sections for oxytetracycline uses in food-producing animals.
     21 CFR 558.76 is amended to add conditions of use 
previously approved under NADA 141-137 for use of bacitracin 
methylenedisalicylate in the manufacture of Type C medicated feeds for 
broiler and replacement chickens (87 FR 76418, December 14, 2022).
     21 CFR 558.355 is amended to revise a caution statement on 
labeling of monensin Type A medicated articles for use in broiler 
breeder replacement chickens.

[[Page 16546]]

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.''

List of Subjects

    Administrative practice and procedure, Animal drugs, Labeling, 
Reporting and recordkeeping requirements.

21 CFR Part 516

    Administrative practice and procedure, Animal drugs, Confidential

21 CFR Part 556

    Therefore, under the Federal Food, Drug, and Cosmetic Act and under 
authority delegated to the Commissioner of Food and Drugs, 21 CFR parts 
510, 516, 520, 522, 524, 526, 529, 556, and 558 are amended as follows:
