# FOR FURTHER INFORMATION CONTACT:

# SUPPLEMENTARY INFORMATION:

                    Phoenix Scientific, Inc., 3915 South 48th Street Terrace, P.O. Box 6457, St. Joseph, MO 64506-0457, filed ANADA 200-286 that provides for use of PHOENECTINTM                     (ivermectin) Paste 1.87%. The ANADA provides for oral use of ivermectin paste for the treatment and control of various species of harmful gastrointestinal parasites in horses. The ANADA is approved as a generic copy of Merial Ltd.'s NADA 134-314 for EQVALAN® (ivermectin) Paste for Horses. ANADA 200-286 is approved as of September 20, 2000, and the regulations are amended in 21 CFR 520.1192 to reflect the approval. The basis for approval is discussed in the freedom of information summary.                 

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.

# List of Subjects in 21 CFR Part 520

      - Animal drugs
