21 CFR Part 520


Oral Dosage Form New Animal Drugs; Ivermectin Paste

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 supplemental new animal drug 
application (NADA) filed by Merial Ltd. The supplemental NADA provides 
revised labeling for ivermectin oral paste used in horses.

DATES: This rule is effective October 4, 2004.

FOR FURTHER INFORMATION CONTACT: Martine Hartogensis, Center for 
Veterinary Medicine (HFV-216), Food and Drug Administration, 7519 
Standish Pl., Rockville, MD 20855, 301-827-7815, e-mail: 
[email protected].

SUPPLEMENTARY INFORMATION: Merial Ltd., 3239 Satellite Blvd., Bldg. 
500, Duluth, GA 30096-4640, filed a supplement to NADA 134-314 for 
EQVALAN (ivermectin 1.87 percent) Paste for Horses. The supplemental 
application provides for revisions to the labeled indications. 
Specifically, under the sub-heading ``Small Strongyles,'' the labeling 
has been revised to separate the listing of adult species from the 
fourth-stage larvae. The supplemental NADA is approved as of August 9, 
2004, and 21 CFR 520.1192 is amended 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.
    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.
