21 CFR Part 522

Implantation or Injectable Dosage Form New Animal Drugs; 
Ivermectin

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 abbreviated new animal drug 
application (ANADA) filed by Norbrook Laboratories, Ltd. The ANADA 
provides for use of a one percent ivermectin solution by subcutaneous 
injection in cattle, swine, reindeer, and American bison for the 
treatment and control of various internal and external parasites.

DATES: This rule is effective May 17, 2007.

FOR FURTHER INFORMATION CONTACT:  John K. Harshman, Center for 
Veterinary Medicine (HFV-104), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-827-0169, e-mail: 
[email protected].

SUPPLEMENTARY INFORMATION: Norbrook Laboratories, Ltd., Station Works, 
Newry BT35 6JP, Northern Ireland, filed supplemental ANADA 200-437 that 
provides for use of NOROMECTIN (ivermectin) Injection for Cattle and 
Swine by subcutaneous injection in cattle, swine, reindeer, and 
American bison for the treatment and control of various internal and 
external parasites. Norbrook Laboratories, Ltd.'s NOROMECTIN Injection 
for Cattle and Swine is approved as a generic copy of Merial, Ltd.'s 
IVOMEC Injection for Cattle and Swine approved under NADA 128-409. The 
ANADA is approved as of April 20, 2007, and the regulations are amended 
in 21 CFR 522.1192 to reflect the approval and a current format.
    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.
    FDA has determined under 21 CFR 25.33(a)(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.
