The supplemental NADA is approved as of April 25, 1994, and the regulations are amended in 21 CFR 520.531 to reflect the approval. Approval of this supplement does not require submission of new safety or effectiveness data. This supplement provides for use of a larger tablet with increased drug concentration to be given at the currently approved use level. However, in accordance with the freedom of information provisions of part 20 (21 CFR part 20) and Sec. 514.11(e)(2)(ii) (21 CFR 514.11(e)(2)(ii)), a freedom of information summary is provided for the revised labeling. Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), this approval does not qualify for marketing exclusivity.

The agency has determined under 21 CFR 25.24(d)(1)(iii) 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. List of Subjects in 21 CFR Part 520 Animal drugs.
