The application provides for topical use of 0.5 percent ivermectin solution on cattle for the treatment and control of various species of gastrointestinal nematodes, lungworms, grubs, horn flies, lice, and mites. Med-Pharmex's Ivermectin Pour-On for Cattle is approved as a generic copy of Merial Limited’s IVOMEC® (ivermectin) Pour-On for Cattle, approved under NADA 140-841. ANADA 200-299 is approved as of December 28, 2000, and the regulations in § 524.1193 (21 CFR 524.1193) are amended to reflect the approval. The basis of approval is discussed in the freedom of information summary. Section 524.1193 is further revised to reflect current format and to reflect the expiration of 3 years of marketing exclusivity granted to Merial Ltd,. in 1997 (62 FR 38907, July 21, 1997), for which revisions were made to § 524.1193 (63 FR 44384, August 19, 1998).
In accordance with the freedom of information provisions of 21 CFR part 20 and 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 Dockets Management Branch (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)(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.Start List of Subjects
