Phoenix Scientific, Inc., 3915 South 48th St. Terrace, St. Joseph, MO 64503, filed a supplement to ANADA 200-246 that currently provides for the veterinary prescription use of ANTHELBAN V (pyrantel pamoate) Equine Anthelmintic Suspension, administered orally or by nasogastric tube (stomach tube) to horses and ponies for the removal and control of mature infections of large strongyles (Strongylus vulgaris, S. edentatus, S. equinus); pinworms (Oxyuris equi); large roundworms (Parascaris equorum); and small strongyles. The supplemental ANADA provides for the over-the-counter use of Pyrantel Pamoate Equine Anthelmintic Suspension, an identical formulation labeled for the same conditions of use, except administration by stomach tube, a veterinary procedure. Phoenix Scientific, Inc.'s Pyrantel Pamoate Equine Anthelmintic Suspension is approved as a generic copy of Pfizer, Inc.'s PAMOBAN Horse Wormer Suspension, approved with over-the-counter marketing status under NADA 91-739. The supplemental ANADA is approved as of August 19, 2003, and the regulations are amended in 21 CFR 520.2043 to reflect the approval and the current indications for use. 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.
