Following the withdrawal of approval of these NADAs, Young’s, Inc., is no longer the sponsor of any approved applications. Therefore, 21 CFR 510.600(c) is amended to remove the entries for the sponsor.
Elanco Animal Health’s NADA 30-330 Tylocine Sulfa Tablets is not codified in 21 CFR part 520. Therefore, an amendment to the regulations for this withdrawal is not required.
As provided below, the animal drug regulations are amended to reflect the withdrawal of approvals.
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.
