Phoenix Scientific, Inc., 3915 South 48th St. Terr., St. Joseph, MO 64503, filed ANADA 200-265 that provides for the use of Praziquantel Tablets for the removal and control of certain cestode parasites in dogs. Phoenix Scientific, Inc.'s Praziquantel Tablets are approved as a generic copy of Bayer HealthCare LLC's DRONCIT (praziquantel) Canine Tablets approved under NADA 111-798. The ANADA is approved as of August 28, 2003, and the regulations are amended in 21 CFR 520.1870 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.

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.
