SUPPLEMENTARY INFORMATION: Back to Top

Ivy Laboratories, Division of Ivy Animal Health, Inc., 8857 Bond St., Overland Park, KS 66214, filed ANADA 200-422 for use of HEIFERMAX 500 (melengestrol acetate) Liquid Premix and RUMENSIN (monensin sodium) single-ingredient Type A medicated articles to make, two-way combination drug Type C medicated feeds for heifers fed in confinement for slaughter. Ivy Laboratories' ANADA 200-422 is approved as a generic copy of Pharmacia and Upjohn's NADA 125-476 for combination use of MGA 500 (melengestrol acetate) Liquid Premix and RUMENSIN in cattle feed. The application is approved as of March 22, 2006, and the regulations are amended in 21 CFR 558.342 to reflect the approval. The basis of approval is discussed in freedom of information summary.

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.

The agency has determined under 21 CFR 25.33(a)(2) 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.
