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 Virbac AH, Inc. The NADA provides for 
veterinary prescription use of chewable tablets in dogs containing 
ivermectin, pyrantel pamoate, and praziquantel for the treatment and 
control or prevention of various internal parasites.

DATES:  This rule is effective November 7, 2006.

FOR FURTHER INFORMATION CONTACT:  Melanie R. Berson, Center for 
Veterinary Medicine (HFV-110), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-827-7540, e-mail: 
[email protected].

SUPPLEMENTARY INFORMATION: Virbac AH, Inc., 3200 Meacham Blvd., Ft. 
Worth, TX 76137, filed NADA 141-257 for IVERHART MAX (ivermectin, 
pyrantel pamoate, praziquantel) Chewable Tablets that provides for 
veterinary prescription use of chewable tablets in dogs containing 
ivermectin, pyrantel pamoate, and praziquantel for the treatment and 
control or prevention of various internal parasites. The NADA is 
approved as of October 13, 2006, and 21 CFR part 520 is amended by 
adding new Sec.  520.1199 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 (the act) (21 U.S.C. 360b(c)(2)(F)(ii)), this approval 
qualifies for 3 years of marketing exclusivity beginning October 13, 
2006.
    FDA has determined under 21 CFR 25.33 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
