Oral Dosage Form New Animal Drugs; Ivermectin Meal

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of a new animal drug application 
(NADA) filed by Merial, Ltd. The NADA provides for use of ivermectin 
meal for the control of various species of internal parasites in 
horses.

DATES: This rule is effective January 11, 2005.

FOR FURTHER INFORMATION CONTACT: Melanie R. Berson, Center for 
Veterinary Medicine (HFV-110), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-827-7543, e-mail: 
[email protected].

SUPPLEMENTARY INFORMATION: Merial, Ltd., 3239 Satellite Blvd., Bldg. 
500, Duluth, GA 30096-4640, filed NADA 141-241 for ZIMECTERIN-EZ 
(ivermectin) 0.6% w/w for Horses. The application provides for use of 
ivermectin meal for the control of various species of internal 
parasites in horses. The NADA is approved as of December 16, 2004, and 
part 520 (21 CFR part 520) is amended by adding new Sec.  520.1194 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 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 December 16, 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.
