SUPPLEMENTARY INFORMATION:

Pharmacia & Upjohn Co., 7000 Portage Rd., Kalamazoo, MI 49001-0199, filed NADA 141-209 for NAXCEL XT (ceftiofur crystalline free acid) Sterile Suspension. The NADA provides for the veterinary prescription use of ceftiofur crystalline free acid suspension in beef and nonlactating dairy cattle, by subcutaneous injection in the ear, for the treatment of BRD (shipping fever, pneumonia) associated with Mannheimia haemolytica, Pasteurella multocida, and Haemophilus somnus and for the control of respiratory disease in cattle at high risk of developing BRD associated with M. haemolytica, P. multocida, and H. somnus. The application is approved as of September 5, 2003, and the regulations are amended in 21 CFR part 522 by adding new § 522.315 to reflect the approval. In addition, 21 CFR 556.113 is being amended to add an acceptable single-dose intake for residues of ceftiofur at the injection site and a tolerance for residues at the injection site. 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.

Under section 512(c)(2)(F)(ii) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(ii)), this approval qualifies for 3 years of marketing exclusivity beginning September 5, 2003.

The agency has determined under 21 CFR 25.33(d)(5) 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.
