21 CFR Part 520


Oral Dosage Form New Animal Drugs; Altrenogest

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 Intervet, Inc. The supplemental NADA 
provides for revised food safety labeling for altrenogest oral solution 
used in horses.

DATES: This rule is effective February 21, 2008.

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, e-mail: 
[email protected].

SUPPLEMENTARY INFORMATION: Intervet, Inc., P.O. Box 318, 29160 Intervet 
Lane, Millsboro, DE 19966, filed a supplement to NADA 131-310 for REGU-
MATE (altrenogest), an oral solution administered to mares for 
suppression of estrus. The supplemental application provides for a 
revised warning statement on product labeling. The supplemental NADA is 
approved as of January 18, 2008, and 21 CFR 520.48 is amended to 
reflect the approval.
    Approval of this supplemental NADA did not require review of 
additional safety or effectiveness data or information. Therefore, a 
freedom of information summary is not required.
    The agency 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.
