SUPPLEMENTARY INFORMATION:

Heska Corp., 1825 Sharp Point Dr., Fort Collins, CO 80525, filed ANADA 200-338 that provides for veterinary prescription use of TRI-HEART PLUS (ivermectin and pyrantel pamoate) Chewable Tablets for prevention of canine heartworm disease caused by Dirofilaria immitis and for treatment and control of ascarids (Toxocara canis, Toxascaris leonina) and hookworms (Ancylostoma caninum, A. braziliense, and Uncinaria stenocephala) in dogs. Heska Corp.'s TRI-HEART PLUS Chewable Tablets is approved as a generic copy of Merial's HEARTGARD Plus Chewables, approved under NADA 140-971. ANADA 200-338 is approved as of August 13, 2003, and 21 CFR 520.1196 is amended to reflect the approval. The basis of approval is discussed in the freedom of information summary.

In addition, Heska Corp. is not currently listed in the animal drug regulations as a sponsor of an approved application. At this time, 21 CFR 510.600(c) is being amended to add entries for the firm.

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)(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.
