End Further Info End Preamble Start Supplemental Information


Combe, Inc., 1101 Westchester Ave., White Plains, NY 10604, filed a supplement to NADA 5-236 that provides for the use of Sulfodene® (2-mercaptobenzothiazole) skin medication for dogs as an aid in the treatment of hot spots (moist dermatitis) and as first aid for scrapes and abrasions. The supplemental NADA provides for revisions to labeling. The NADA is approved as of July 3, 2000, and the regulations in 21 CFR 524.1376 are amended to reflect the approval.

Approval of this supplemental NADA did not require review of any safety or effectiveness data. Therefore, a freedom of information summary is not required.

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.
