Schering-Plough Animal Health Corp., 556 Morris Ave., Summit, NJ 07901, filed a supplement to NADA 106-965 for use of TRIBRISSEN (trimethoprim and sulfadiazine) 48% Injection administered to horses as a systemic antibacterial. The supplement provides for revised food safety labeling. The supplemental NADA is approved as of April 26, 2006, and the regulations are amended in § 522.2610 (21 CFR 522.2610) to reflect the approval and a current format. The basis of approval is discussed in the freedom of information summary.
In addition, FDA has found that a 1997 change of sponsorship for NADA 106-965 (62 FR 61625, November 19, 1997) is not reflected in the Code of Federal Regulations. Accordingly, § 522.2610 is being revised to reflect the correct sponsor drug labeler code. This action is being taken to improve the accuracy of the regulations.
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.Start List of Subjects
