**SUPPLEMENTARY INFORMATION:**
Modern Veterinary Therapeutics, LLC, 1550 Madruga Ave., suite 329, Coral Gables, FL 33146, filed ANADA 200-446 for the use of BUTORPHINE (butorphanol tartrate, USP) Veterinary Injection in cats for the relief of pain. Modern Veterinary Therapeutics' BUTORPHINE Veterinary Injection is approved as a generic copy of TORBUGESIC-SA (butorphanol tartrate, USP) Veterinary Injection, approved under NADA 141-047 held by Fort Dodge Animal Health, Division of Wyeth, a wholly owned subsidiary of Pfizer, Inc. The ANADA is approved as of March 26, 2010, and the regulations in 21 CFR 522.246 are amended to reflect the approval.
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 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.
