SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of a new animal drug application 
(ANADA) filed by IVX Animal Health, Inc. The ANADA provides for 
veterinary prescription use of griseofulvin powder orally as a systemic 
antifungal agent in horses.

DATES: This rule is effective July 5, 2006.

FOR FURTHER INFORMATION CONTACT: Daniel A. Benz, Center for Veterinary 
Medicine (HFV-104), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 301-827-0223, e-mail: [email protected].

SUPPLEMENTARY INFORMATION: IVX Animal Health, Inc., 3915 South 48th 
Street Ter., St. Joseph, MO 64503, filed ANADA 200-391 that provides 
for veterinary prescription use of Griseofulvin Powder Microsize, 
orally as a systemic antifungal agent in horses. IVX Animal Health's 
Griseofulvin Powder Microsize, is approved as a generic copy of 
Schering-Plough Animal Health Corp.'s FULVICIN-U/F (griseofulvin) 
Powder approved under NADA 39-792. The ANADA is approved as of June 1, 
2006, and the regulations are amended in 21 CFR 520.1100 to reflect the 
approval and a current format. The basis of approval is discussed in 
the freedom of information summary.
    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(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.
