Norbrook Laboratories, Ltd., Station Works, Newry, BT35 6JP, Northern Ireland, filed NADA 141-312 that provides for veterinary prescription use of HEXASOL (oxytetracycline and flunixin meglumine) Injection for the treatment of bacterial pneumonia associated with Pasteurella spp. and for the control of associated pyrexia in beef and non-lactating dairy cattle. The application is approved as of November 29, 2010, and the regulations in part 522 (21 CFR part 522) are revised by adding 21 CFR 522.1664.

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 act (21 U.S.C. 360b(c)(2)(F)(ii)), this approval qualifies for 3 years of marketing exclusivity beginning on the date of approval.

The Agency has determined under 21 CFR 25.33 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.
