FDA has noticed that the approved conditions of use for GENTOCIN DURAFILM (gentamicin sulfate and betamethasone acetate) Ophthalmic Solution, sponsored by Intervet, Inc., 56 Livingston Ave., Roseland, NJ 07068 under NADA 34-267 are not codified. When this NADA was approved in 1967, codification of approved conditions of use for NADAs was not required. Accordingly, the regulations are amended in 21 CFR part 524 by adding § 524.1044i to reflect the approval. This action is being taken to comply with section 512(i) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360b(i)) and to improve the accuracy of the regulations.

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.
