DEPARTMENT OF HEALTH AND HUMAN SERVICES

Food and Drug Administration

21 CFR Part 520


Oral Dosage Form New Animal Drugs; Phenylbutazone Tablets

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of two supplemental new animal 
drug applications (NADAs) filed by IVX Animal Health, Inc. The 
supplemental NADAs provide revised labeling for phenylbutazone tablets 
used in horses and dogs.

DATES: This rule is effective February 13, 2008.

FOR FURTHER INFORMATION CONTACT: Melanie R. Berson, Center for 
Veterinary Medicine (HFV-110), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 240-276-8337, e-mail: 
[email protected].

SUPPLEMENTARY INFORMATION: IVX Animal Health, Inc., 3915 South 48th 
Street Ter., St. Joseph, MO 64503, filed supplements to NADA 91-818 and 
NADA 94-170 for Phenylbutazone Tablets. The supplemental applications 
provide for revisions to warning statements on product labeling. The 
supplemental NADAs are approved as of January 17, 2008, and 21 CFR 
520.1720a is amended to reflect the approval.
    Approval of these supplemental NADAs did not require review of 
additional safety or effectiveness data or information. Therefore, a 
freedom of information summary is not required.
    The agency has determined under 21 CFR 25.33(a)(1) that these 
actions are of a type that do not individually or cumulatively have a 
significant effect on the human environment. Therefore, neither an 
environmental assessment nor an environmental impact statement is 
required.
    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.
