SUPPLEMENTARY INFORMATION:

IVX Animal Health, Inc., 3915 South 48th Street Ter., St. Joseph, MO 64503, filed ANADA 200-408 that provides for veterinary prescription use of Butorphanol Tartrate Injection (2mg/mL) in cats for the relief of pain. IVX Animal Health, Inc.'s Butorphanol Tartrate Injection (2mg/mL) is approved as a generic copy of Fort Dodge Animal Health, a Div. of Wyeth's TORBUGESIC-SA (butorphanol tartrate, USP), approved under NADA 141-047. The ANADA is approved as of April 20, 2007, and the regulations are amended in 21 CFR 522.246 to reflect the approval and a current format.

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.

FDA 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.
