Supplementary information:

Pfizer, Inc., 235 East 42d St., New York, NY 10017, filed a supplement to NADA 141-244 for DRAXXIN (tulathromycin) Injectable Solution. The supplemental NADA provides for the use of tulathromycin injectable solution for control of SRD associated with Actinobacillus pleuropneumoniae, Pasteurella multocida, and Mycoplasma hyopneumoniae in groups of pigs where SRD has been diagnosed. The application is approved as of September 8, 2009, and the regulations are amended in § 522.2630 (21 CFR 522.2630) to reflect the approval.

In addition, FDA has noticed that the approved indications for use of this product in cattle (73 FR 58872, October 8, 2008) were inaccurately codified. At this time, § 522.2630 is being amended to correctly describe these indications for use. 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.

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

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.
