Final rule.


The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of an original abbreviated new animal drug application (ANADA) filed by Cross Vetpharm Group, Ltd. The ANADA provides for use of gentamicin sulfate soluble powder used to make medicated drinking water for swine.


This rule is effective January 27, 2012.


John K. Harshman, Center for Veterinary Medicine (HFV-170), Food and Drug Administration, 7500 Standish Pl., Rockville, MD 20855, (240) 276-8197, email:


Cross Vetpharm Group, Ltd., Broomhill Rd., Tallaght, Dublin 24, Ireland, filed ANADA 200-494 for use of GENTAMED (gentamicin sulfate) Soluble Powder used to make medicated drinking water for swine. Cross Vetpharm Group's Gentamicin Soluble Powder is approved as a generic copy of GARACIN (gentamicin sulfate) Soluble Powder, sponsored by Intervet Inc., under NADA 133-836. The abbreviated application is approved as of December 14, 2011, and the regulations are amended in 21 CFR 520.1044c 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.

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.
