New Animal Drugs; Ceftiofur
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 Pharmacia Upjohn Co. The supplemental NADA provides for use of ceftiofur crystalline free acid suspension via a new injection site in beef and nonlactating dairy cattle, for use in lactating dairy cattle for the treatment of respiratory disease, and for the establishment of a 13-day pre-slaughter withdrawal period in cattle. FDA is also amending the regulations to revise the tolerance for residues of ceftiofur in bovine kidney to accommodate these new conditions of use.

SUPPLEMENTARY INFORMATION: Back to Top
Pharmacia Upjohn Co., a Division of Pfizer, Inc., 235 East 42nd St., New York, NY 10017, filed a supplement to NADA 141-209 for EXCEDE (ceftiofur crystalline free acid) Sterile Suspension, approved for veterinary prescription use by injection in cattle for respiratory disease. The supplemental application provides for subcutaneous injection in beef and nonlactating dairy cattle in the posterior aspect of the ear where it attaches to the head (base of the ear), for use in lactating dairy cattle by subcutaneous injection in the base of the ear for the treatment of bovine respiratory disease, and for the establishment of a 13-day pre-slaughter withdrawal period in cattle. FDA is also amending the regulations to revise the tolerance for residues of ceftiofur in bovine kidney to accommodate these new conditions of use. The application is approved as of June 2, 2006, and the regulations are amended in 21 CFR 522.315 and 556.113 to reflect the approval. 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 the 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)(iii) of the Federal Food, Drug, and Cosmetic Act (the act) (21 U.S.C. 360b(c)(2)(F)(iii)), this approval qualifies for 3 years of marketing exclusivity beginning June 2, 2006. The 3 years of marketing exclusivity applies only to the new administration site and new indication for which this supplement is approved.
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.
