21 CFR Part 520


Oral Dosage Form New Animal Drugs; Levamisole Powder for Oral 
Solution

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 Schering-Plough Animal Health Corp. The 
supplemental NADA revises the description of various internal parasites 
in labeling for levamisole powder, used to make a drench solution for 
oral administration to cattle and sheep.

DATES: This rule is effective March 2, 2004.

FOR FURTHER INFORMATION CONTACT: Janis R. Messenheimer, Center for 
Veterinary Medicine (HFV-130), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-827-7578, e-mail: 
[email protected].

SUPPLEMENTARY INFORMATION: Schering-Plough Animal Health Corp., 1095 
Morris Ave., Union, NJ 07083, filed a supplement to NADA 112-051 for 
LEVASOLE (levamisole) Soluble Drench Powder revising the description of 
various internal parasites in labeling for levamisole powder, used to 
make a drench solution for oral administration to cattle and sheep. The 
supplemental NADA is approved as of December 23, 2003, and the 
regulations are revised in 21 CFR 520.1242a 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.
