21 CFR Parts 500, 522, and 556

[Docket No. FDA-2011-N-0003]


Animal Drugs, Feeds, and Related Products; Eprinomectin; N-
Methyl-2-Pyrrolidone

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 an original new animal drug 
application (NADA) filed by Merial Ltd. The NADA provides for the 
veterinary prescription use of eprinomectin by

[[Page 72618]]

injection for the treatment and control of internal and external 
parasites of cattle on pasture with persistent effectiveness. The 
current tolerance for the marker residue for total residues of 
eprinomectin in edible tissues of cattle is being lowered. The method 
of detection for residues of the carcinogenic excipient n-methyl-2-
pyrrolidone (NMP) in edible tissues of cattle is also being codified.

DATES: This rule is effective November 25, 2011. The incorporation by 
reference of a certain method listed in this rule is approved by the 
Director of the Federal Register as of November 25, 2011.

FOR FURTHER INFORMATION CONTACT: Cindy L. Burnsteel, Center for 
Veterinary Medicine (HFV-130), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, (240) 276-8341, email:

SUPPLEMENTARY INFORMATION: Merial Ltd., 3239 Satellite Blvd., Bldg. 
500, Duluth, GA 30096-4640 filed NADA 141-327 that provides for 
veterinary prescription use of LONGRANGE (eprinomectin) Extended-
Release Injectable Parasiticide for the treatment and control of 
internal and external parasites of cattle on pasture with persistent 
effectiveness. The NADA is approved as of September 26, 2011, and the 
regulations are amended in 21 CFR part 522 to reflect the approval.
    As a consequence of the residue depletion characteristics of this 
product, the current tolerance for the marker residue for eprinomectin 
in the target tissue of cattle is being lowered. Accordingly, the 
regulations are amended in 21 CFR part 556. Elsewhere in this issue of 
the Federal Register, the approved NADA for an eprinomectin topical 
solution used on cattle is being supplemented to provide for this lower 
tolerance.
    In addition, FDA has determined that an inactive ingredient in this 
product, the excipient n-methyl-2-pyrrolidone (NMP), is a carcinogen. 
As required by section 512(d)(1)(I) of the Federal Food, Drug, and 
Cosmetic Act (the FD&C Act) (21 U.S.C. 360b(d)(1)(I)), a method of 
detection for residues of NMP in edible tissues of cattle is being 
codified in 21 CFR part 500, new subpart F, through incorporation by 
reference.
    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 FD&C Act, this approval 
qualifies for 3 years of marketing exclusivity beginning on the date of 
approval.
    The Agency has carefully considered the potential environmental 
impact of this action and has concluded that the action will not have a 
significant impact on the human environment and that an environmental 
impact statement is not required. FDA's finding of no significant 
impact and the evidence supporting that finding, contained in an 
environmental assessment, may be seen in the Division of Dockets 
Management between 9 a.m. and 4 p.m., Monday through Friday.
    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.
