21 CFR Part 520

[Docket No. FDA-2008-N-0039]


Oral Dosage Form New Animal Drugs; Phenylbutazone Tablets and 
Boluses

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 a supplemental new animal drug 
application (NADA) filed by First Priority, Inc. The supplemental 
application provides for revising the description of a 1-gram oral 
dosage form of phenylbutazone from tablet to bolus.

DATES:  This rule is effective January 12, 2009.

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: First Priority, Inc., 1585 Todd Farm Dr., 
Elgin, IL 60123, filed a supplement to NADA 48-647 for the veterinary 
prescription use of PRIBUTAZONE (phenylbutazone) Tablets in horses for 
the relief of inflammatory conditions associated with the 
musculoskeletal system. The supplemental application provides for 
revising the description of this 1-gram oral dosage form of 
phenylbutazone from tablet to bolus. The supplemental NADA is approved 
as of December 10, 2008, and 21 CFR 520.1720a is amended to reflect the 
approval.
    Approval of this supplemental NADA 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(d)(1) that this action 
is of a type that does 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.
