ACTION: Final rule. SUMMARY: The Food and Drug Administration

(FDA)is amending the animal drug regulations to reflect approval of a supplemental new animal drug application

(NADA)filed by Schering-Plough Animal Health Corp. The supplemental NADA provides for the addition of once-daily administration to the dosage regimens for gentamicin/mometasone/clotrimazole otic suspension used to treat otitis externa in dogs and for revision of the indications to reflect a current format. DATES: This rule is effective March 31, 2003. FOR FURTHER INFORMATION CONTACT: Melanie R.

SUPPLEMENTARY INFORMATION: Schering-Plough Animal Health Corp., 1095 Morris Ave., P.O. Box 3182, Union, NJ 07083, filed a supplement to NADA 141-177 that provides for once-daily administration of MOMETAMAX (gentamicin sulfate/mometasone furoate monohydrate/clotrimazole) Otic Suspension for the treatment of otitis externa in dogs caused by susceptible strains of yeast ( *Malassezia pachydermatis* ) and bacteria ( *Pseudomonas* spp. [including *P. aeruginosa* ], coagulase-positive staphylococci, *Enterococcus faecalis* , *Proteus mirabilis* , and beta-hemolytic streptococci). The indications for use are also being revised to reflect a current format. The supplemental NADA is approved as of January 9, 2003, and the regulations are amended in 21 CFR 524.1044h to reflect the approval. The basis of approval is discussed in the freedom of information summary. In accordance with the freedom of information provisions of 21 CFR part 20 and 21 CFR 514.11(e)(2)(ii), a summary of safety and effectiveness data and information submitted to support approval of this application may be seen in the Dockets Management Branch (HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, Rockville, MD 20852, between 9 a.m. and 4 p.m., Monday through Friday. Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and Cosmetic Act (the act) (21 U.S.C. 360b(c)(2)(F)(iii)), this supplemental approval qualifies for 3 years of marketing exclusivity beginning January 9, 2003. The agency has determined under 21 CFR 25.33(d)(1) 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. 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.

Therefore, under the Federal Food, Drug, and Cosmetic Act and under authority delegated to the Commissioner of Food and Drugs and redelegated to the Center for Veterinary Medicine, 21 CFR part 524 is amended as follows: PART 524—OPHTHALMIC AND TOPICAL DOSAGE FORM NEW ANIMAL DRUGS 1.
