Phoenix Scientific, Inc., 3915 South 48th St. Terrace, St. Joseph, MO 64503, filed ANADA 200-386 for Levamisole Hydrochloride Soluble Drench Powder used to make a drench solution for oral administration to cattle and sheep which is effective against various internal parasites. Phoenix Scientific's Levamisole Hydrochloride Soluble Drench Powder is approved as a generic copy of Schering-Plough Animal Health Corp.'s, LEVASOL (levamisole hydrochloride) Soluble Drench Powder, approved under NADA 112-051. The ANADA is approved as of December 17, 2004, and the regulations are amended in 21 CFR 520.1242a to reflect the approval. The basis of approval is discussed in the 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.

FDA 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.
