21 CFR Part 520

[Docket No. FDA-2011-N-0003]

Oral Dosage Form New Animal Drugs; Change of Sponsor; 
Chlortetracycline; Sulfamethazine

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 five new animal 
drug applications (NADAs) from Fort Dodge Animal Health, Division of 
Wyeth Holdings Corp., a wholly owned subsidiary of Pfizer, Inc., to 
Boehringer Ingelheim Vetmedica, Inc.

DATES: This rule is effective August 11, 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: Fort Dodge Animal Health, Division of Wyeth 
Holdings Corp., a wholly owned subsidiary of Pfizer, Inc., 235 East 42d 
St., New York, NY 10017 has informed FDA that it has transferred 
ownership of, and all rights and interest in, five approved NADAs 
(NADAs 055-012, 055-018, 055-039, 065-071, and 065-440) to Boehringer 
Ingelheim Vetmedica, Inc., 2621 North Belt Highway, St. Joseph, MO 
64506-2002. Accordingly, the Agency is amending the regulations in 21 
CFR part 520 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.
