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

(NADA)filed by Animal Health Pharmaceuticals, LLC. The NADA provides for veterinary prescription use of an oral suspension of sulfadiazine and pyrimethamine for the treatment of equine protozoal myeloencephalitis (EPM).

SUPPLEMENTARY INFORMATION: Animal Health Pharmaceuticals, LLC, 1805 Oak Ridge Circle, suite 101, St. Joseph, MO 64506, filed NADA 141-240 for veterinary prescription use of REBALANCE (sulfadiazine/pyrimethamine) Antiprotozoal Oral Suspension for the treatment of EPM caused by *Sarcocystis neurona* . The NADA is approved as of November 5, 2004, and 21 CFR part 520 is amended by adding new § 520.2215 to reflect the approval. The basis of approval is discussed in the freedom of information summary. In addition, Animal Health Pharmaceuticals, LLC, is not currently listed in the animal drug regulations as a sponsor of an approved application. At this time, 21 CFR 510.600(c) is being amended to add entries for the firm. 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 Division of Dockets Management (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)(ii) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(ii)), this approval qualifies for 3 years of marketing exclusivity beginning November 5, 2004. 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.
