2013-27917. Withdrawal of Approval of New Animal Drug Applications; Carbarsone; Roxarsone

AGENCY:

Food and Drug Administration, HHS.

ACTION:

Final rule.

SUMMARY:

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect the withdrawal approval of three new animal drug applications (NADAs) for roxarsone or carbarsone Type A medicated articles at the sponsor's request because the products are no longer manufactured or marketed.

DATES:

This rule is effective December 2, 2013.

FOR FURTHER INFORMATION CONTACT:

John Bartkowiak, Center for Veterinary Medicine (HFV-212), Food and Drug Administration, 7519 Standish Pl., Rockville, MD 20855, 240-276-9079, [e-mail].

SUPPLEMENTARY INFORMATION:

Zoetis Inc., 333 Portage St., Kalamazoo, MI 49007, has requested that FDA withdraw approval of the following three NADAs because the products, used to manufacture Type B and Type C medicated feeds, are no longer manufactured or marketed: NADA 007-891 for 3-NITRO (roxarsone) Type A medicated articles, NADA 092-953 for Roxarsone Type A Medicated Articles, and NADA 010-285 for CARB-O-SEP (carbarsone) Type A medicated article.

Elsewhere in this issue of the Federal Register, FDA gave notice that approval of NADAs 007-891, 010-285, and 092-953, and all supplements and amendments thereto, is withdrawn, effective December 2, 2013. As provided in the regulatory text of this document, the animal drug regulations are amended to reflect these voluntary withdrawals of approval.

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.
