End Further Info End Preamble Start Supplemental Information


Intervet, Inc., P.O. Box 318, 405 State St., Millsboro, DE 19966, filed a supplement to NADA 121-473 that provides for oral use in dogs of PANACUR-C (fenbendazole) Granules 22.2% for removal of certain internal parasites. The supplemental NADA provides for change from prescription to over-the-counter marketing status. The supplemental NADA is approved as of March 19, 2002, and the regulations are amended in 21 CFR 520.905b to reflect the approval. The basis of approval is discussed in the freedom of information summary. Section 520.905b is also being revised to reflect a current format.

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(d)(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.
