End Further Info End Preamble Start Supplemental Information


Pharmacia & Upjohn Co., a Div. of Pfizer, Inc., 235 E. 42d St., New York, NY 10017, filed a supplement to NADA 141-077 for ADSPEC (spectinomycin sulfate) Sterile Solution used for the treatment of bovine respiratory disease associated with several bacterial pathogens. The supplemental NADA provides for revising nomenclature for two bacterial pathogens on product labeling. The supplemental NADA is approved as of May 10, 2007, and the regulations in 21 CFR 522.2121 are amended to reflect the approval and a current format.

Approval of this supplemental NADA did not require review of additional safety or effectiveness data or information. Therefore, a freedom of information summary is not required.

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.
