21 CFR Part 520

[Docket No. FDA-2009-N-0665]


Oral Dosage Form New Animal Drugs; Fenbendazole Suspension

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 Intervet, Inc. The supplemental NADA 
provides for a revised human food safety warning for use of 
fenbendazole suspension in horses.

DATES:  This rule is effective April 17, 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: Intervet, Inc., P.O. Box 318, 29160 Intervet 
Lane, Millsboro, DE 19966, filed a supplement to NADA 104-494 that 
provides for use of PANACUR (fenbendazole) Suspension 10% in horses for 
the control of various internal parasites. The supplemental NADA 
provides for a revised human food safety warning on product labeling. 
The supplemental NADA is approved as of March 25, 2009, and the 
regulations are amended in 21 CFR 520.905a to reflect the approval and 
a current format.
    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(a)(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.
