21 CFR Part 520

Oral Paste

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 Schering-Plough Animal Health Corp. The 
supplemental NADA provides for revised food safety labeling for 
trimethoprim and sulfadiazine oral paste, administered to horses as a 
systemic antibacterial.

DATES: This rule is effective May 31, 2006.

FOR FURTHER INFORMATION CONTACT: Melanie R. Berson, Center for 
Veterinary Medicine (HFV-110), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-827-7540, e-mail: 
[email protected].

SUPPLEMENTARY INFORMATION: Schering-Plough Animal Health Corp., 556 
Morris Ave., Summit, NJ 07901, filed a supplement to NADA 131-918 for 
use of TRIBRISSEN (trimethoprim and sulfadiazine) 400 Paste, 
administered orally to horses as a systemic antibacterial. The 
supplement provides for revised food safety labeling. The supplemental 
NADA is approved as of April 25, 2006, and the regulations are amended 
in 21 CFR 520.2611 to reflect the approval and a current format. The 
basis of approval is discussed in the freedom of information summary.
    In accordance with the freedom of information provisions of 21 CFR 
part 20 and 21 CFR 514.11(e)(2)(ii), a summary of safety and 
effectiveness data and information submitted to support approval of 
this application may be seen in the Division of Dockets Management 
(HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, 
Rockville, MD 20852, between 9 a.m. and 4 p.m., Monday through Friday.
    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.

Therefore, under the Federal Food, Drug, and Cosmetic Act and under
