**AGENCY:**
Food and Drug Administration, HHS.
**ACTION:**
Final rule.
**SUMMARY:**
The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect a change of sponsor for a new animal drug application (NADA) from Virbac AH, Inc., to Cross Vetpharm Group Ltd.
**DATES:**
This rule is effective July 8, 2011.
**FOR FURTHER INFORMATION CONTACT:**
Steven D. Vaughn, Center for Veterinary Medicine (HFV-100), Food and Drug Administration, 7520 Standish Pl., Rockville, MD 20855, 240-276-8300, e-mail: *[email protected].*
**SUPPLEMENTARY INFORMATION:**
Virbac AH, Inc., 3200 Meacham Blvd., Ft. Worth, TX 76137, has informed FDA that it has transferred ownership of, and all rights and interest in, NADA 092-150 for Purina Horse & Colt Wormer (pyrantel tartrate) to Cross Vetpharm Group Ltd., Broomhill Rd., Tallaght, Dublin 24, Ireland. Accordingly, the regulations are amended in 21 CFR 520.2045 to reflect the transfer of ownership.
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.
**List of Subjects in 21 CFR Part 520**
Animal drugs.
Therefore, under the Federal Food, Drug, and Cosmetic Act and under authority delegated to the Commissioner of Food and Drugs and redelegated to the Center for Veterinary Medicine, 21 CFR part 520 is amended as follows:
**21 CFR Part 520**
**PART 520—ORAL DOSAGE FORM NEW ANIMAL DRUGS**
