21 CFR Part 520

[Docket No. FDA-2010-N-0002]


Oral Dosage Form New Animal Drugs; Praziquantel and Pyrantel

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 Bayer HealthCare LLC. The supplement 
provides for two new sizes of praziquantel and pyrantel pamoate tablets 
used in cats and kittens for the removal of various internal parasites 
and for a revised kitten age and weight restriction.

DATES: This rule is effective September 3, 2010.

FOR FURTHER INFORMATION CONTACT: Melanie R. Berson, Center for 
Veterinary Medicine (HFV-110), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 240-276-8337, email:

SUPPLEMENTARY INFORMATION: Bayer HealthCare LLC, Animal Health 
Division, P.O. Box 390, Shawnee Mission, KS 66201, filed a supplement 
to NADA 141-008 for DRONTAL (praziquantel and pyrantel pamoate) Tablets 
used in cats and kittens for the removal of various internal parasites. 
The supplement provides for two new tablet sizes and for a revised 
kitten age and weight restriction. The supplemental NADA is approved as 
of June 15, 2010, and 21 CFR 520.1871 is amended to reflect the 
approval.
    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.
