As provided in the regulatory text of this document, the animal drug regulations are amended to reflect these withdrawals of approval and a current format.
Following these changes of sponsorship, Abraxis Pharmaceutical Products, Furst-McNess Co., Roche Vitamins, Inc., Waterloo Mills Co., and Wendt Laboratories, Inc., are no longer the sponsors of an approved application. Accordingly, 21 CFR 510.600(c) is being amended to remove the entries for these firms.
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.
