21 CFR Part 526

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


Intramammary Dosage Form New Animal Drugs; Cloxacillin Benzathine

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule; technical amendment.

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

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of a supplementary new animal drug 
application (NADA) filed by Boehringer Ingelheim Vetmedica, Inc. The 
supplement provides for minor revisions to labeling.

DATES: This rule is effective November 22, 2010.

FOR FURTHER INFORMATION CONTACT: Cindy L. Burnsteel, Center for 
Veterinary Medicine (HFV-130), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 240-276-8341, e-mail: 
cindy.burnsteel@fda.hhs.gov.

SUPPLEMENTARY INFORMATION: Boehringer Ingelheim Vetmedica, Inc., 2621 
North Belt Highway, St. Joseph, MO 64506-2002 has filed a supplement to 
NADA 55-058 for DRY-CLOX (cloxacillin benzathine) Intramammary Infusion 
for dry dairy cattle. The supplemental NADA provides for various minor 
revisions to labeling. The supplemental application is approved as of 
October 21, 2010, and the regulations in Sec.  526.464a (21 CFR 
526.464a) are amended to reflect the approval.
    In addition, FDA has noticed that certain portions of Sec.  
526.464a were inadvertently removed when the regulations were amended 
to reflect a change of sponsorship (75 FR 10165, March 5, 2010). At 
this time, the regulations are being amended to reflect fully the 
approved conditions of use of this new animal drug product. This change 
is being made to improve the accuracy of the animal drug regulations.
    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 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

[[Page 71017]]

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.
