-----------------------------------------------------------------------

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 Pharmacia & Upjohn Co., a Division of 
Pfizer, Inc. The supplemental NADA provides for use of progesterone

synchronization of estrus in lactating dairy cows.

FOR FURTHER INFORMATION CONTACT: Suzanne J. Sechen, Center for 
Veterinary Medicine (HFV-126), Food and Drug Administration, 7500

SUPPLEMENTARY INFORMATION: Pharmacia & Upjohn Co., a Division of 
Pfizer, Inc., 235 East 42d St., New York, NY 10017 filed a supplement 
to NADA 141-200 that provides for use of EAZI-BREED CIDR Progesterone 
Intravaginal Inserts and dinoprost tromethamine by injection for 
synchronization of estrus in lactating dairy cows. The NADA is approved 
as of July 22, 2010, and the regulations are amended in 21 CFR 529.1940 
to reflect the approval.
    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)(iii) of the Federal Food, Drug, and 
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), this supplemental approval 
qualifies for 3 years of marketing exclusivity beginning on the date of 
approval.
    The agency 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.

inseminated at the immediately preceding estrus.
    (iii) Limitations. Do not use in beef or dairy heifers of 
insufficient size or age for breeding or in animals with abnormal, 
immature, or infected genital tracts. Do not use in beef cows that are 
fewer than 20 days postpartum. Do not use an insert more than once. To 
prevent the potential transmission of venereal and bloodborne diseases, 
the inserts should be disposed after a single use. Administration of 
vaginal inserts for periods greater than 7 days may result in reduced 
fertility. Dinoprost solution provided by No. 000009 in Sec.  
510.600(c) of this chapter.
