Background The Minor Use and Minor Species Animal Health Act of 2004 (MUMS Act of 2004) (Pub. L. 108–282) amended the FD&C Act to establish regulatory procedures that provide incentives intended to make more drugs legally available to veterinarians and animal owners for the treatment of minor animal species and uncommon diseases in major animal species. In 2007, FDA issued final regulations (72 FR 69108, December 6, 2007) to implement section 572 of the MUMS Act entitled ‘‘Index of Legally Marketed Unapproved New Animal Drugs for Minor Species.’’ These regulations establish administrative procedures and criteria for index listing a new animal drug that provide a basis for legally marketing an unapproved new animal drug for use in a minor species.

SUPPLEMENTARY INFORMATION: 

I. Approvals

    FDA is amending the animal drug regulations to reflect approval 
actions for NADAs and ANADAs during January, February, and March 2024, 
as listed in table 1. In addition, FDA is informing the public of the 
availability, where applicable, of documentation of environmental 
review required under the National Environmental Policy Act (NEPA) and, 
for actions requiring review of safety or effectiveness data, summaries 
of the basis of approval (FOIA Summaries) under the Freedom of 
Information Act (FOIA). These documents, along with marketing 
exclusivity and patent information, may be obtained at Animal Drugs 
@FDA: https://animaldrugsatfda.fda.gov/adafda/views/#/search.

IV. Change of Sponsor Address

    ECO LLC, 344 Nassau St., Princeton, NJ 08540 (drug labeler code 
066916 in 21 CFR 510.600(c)) has informed FDA that it has changed its 
address to 11224 Aurora Ave., Urbandale, IA 50322. The entries in Sec.  
510.600(c) are amended to reflect this action.

V. Technical Amendments

    FDA is making the following amendments to improve the accuracy and 
readability of the animal drug regulations.
     21 CFR 510.600 is amended to remove entries for Heska 
Corp. and Piramal Critical Care, Inc. from the lists of sponsors of 
approved applications, to revise the entries for Cronus Pharma 
Specialities India Private Ltd. and ECO LLC; and to add entries for 
Diamond Animal Health, Inc.
     21 CFR 522.840 is amended to reflect revisions to approved 
labeling for cattle implants containing estradiol.
     21 CFR 522.1940 is amended to reflect the current format 
for regulations and revisions to approved labeling for cattle implants 
containing progesterone and estradiol benzoate.
     21 CFR 522.2343 is amended to reflect revisions to 
approved labeling for cattle implants containing testosterone 
propionate and estradiol benzoate.
     21 CFR 522.2477 is amended to reflect revisions to 
approved labeling for cattle implants containing trenbolone acetate and 
estradiol.
     21 CFR 524.1193 is amended to reflect periods of 
persistent activity for an approved generic ivermectin topical solution 
used in cattle.
     21 CFR 558.485 is amended to reflect an inclusion rate for 
pyrantel tartrate in medicated horse feeds.

VI. 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)). Although deemed 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'' and 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.

List of Subjects

21 CFR Part 510

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

21 CFR Parts 520, 522, 524, and 529

    Animal drugs.

21 CFR Part 558

    Animal drugs, Animal feeds.

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