SUPPLEMENTARY INFORMATION:

Pfizer, Inc., 235 East 42d St., New York, NY 10017-5755, filed NADA 141-207 for A180 (danofloxacin mesylate) Injectable Solution. The NADA provides for the veterinary prescription use of danofloxacin solution in cattle, by subcutaneous injection, for treatment of bovine respiratory disease associated with Mannheimia (Pasteurella) haemolytica and Pasteurella multocida. The application is approved as of September 20, 2002, and the regulations are amended in 21 CFR part 522 by adding new § 522.522 and in 21 CFR part 556 by adding new § 556.169 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 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 Dockets Management Branch (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)(i) of the Federal Food, Drug, and Cosmetics Act (21 U.S.C. 360b(c)(2)(F)(i)), this approval qualifies for 5 years of marketing exclusivity beginning September 20, 2002.

The agency has carefully considered the potential environmental impact of this action and has concluded that the action will not have a significant impact on the human environment and that an environmental impact statement is not required. FDA's finding of no significant impact and the evidence supporting that finding, contained in an environmental assessment, may be seen in the Dockets Management Branch (see ADDRESSES) between 9 a.m. and 4 p.m., Monday through Friday.

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.
