Fort Dodge Animal Health, a 1Division of American Cyanamid Co., P.O. Box 1339, Fort Dodge, IA 50501, is the sponsor of NADA 32-319 for Furox (furazolidone) aerosol powder for use in dogs, horses, ponies, and cattle. The sponsor filed a supplemental NADA requesting removal of topical ocular use of the product in cattle. The supplemental NADA is approved as of November 29, 1999, and the regulations are amended in 21 CFR Start Printed Page 41588524.1005(b)(1), (c)(2)(iii), and (c)(3) to reflect the approval.

The regulations in § 524.1005(b)(1) (21 CFR 524.1005(b)(1)) indicate that Pfizer, Inc., is sponsor of NADA 32-319 for use of a 10 percent furazolidone aerosol powder in dogs, horses, and cattle. The NADA had been acquired by Fort Dodge Animal Health, a Division of American Cyanamid Co. At this time, the regulation is amended in § 524.1005(b) to reflect the sponsor change.

Approval of this supplemental NADA provides for removal of a cattle use. It does not affect the safety or effectiveness data in the application. Therefore, a freedom of information summary is not 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 congressional review requirements in 5 U.S.C. 801-808.
