Gel

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 new animal drug application 
(NADA) filed by Fort Dodge Animal Health, Division of Wyeth. The NADA 
provides for use of a moxidectin and praziquantel oral gel for the 
treatment and control of various species of internal parasites in 
horses and ponies.

DATES: This rule is effective August 27, 2003.

FOR FURTHER INFORMATION CONTACT: Melanie R. Berson, Center for 
Veterinary Medicine (HFV-110), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855; 301-827-7543; e-mail: 
[email protected].

SUPPLEMENTARY INFORMATION: Fort Dodge Animal Health, Div. of Wyeth, 800 
Fifth St. NW., Fort Dodge, IA 50501, filed NADA 141-216 for QUEST PLUS 
(moxidectin 2.0%/praziquantel 12.5%) Gel for the treatment and control 
of various species of internal parasites in horses and ponies. The NADA 
is approved as of May 14, 2003, and part 520 (21 CFR part 520) is 
amended by adding new Sec.  520.1453 to reflect the approval. 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 Dockets Management Branch (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.
    Under section 512(c)(2)(F)(ii) of the Federal Food, Drug, and 
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(ii)), this approval qualifies for 
3 years of marketing exclusivity beginning.
    The agency has determined under 21 CFR 25.33(d)(1) that this action 
is of a type that does not individually or cumulatively have a 
significant effect on the human environment. Therefore,

[[Page 51446]]

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.

List of Subjects in 21 CFR Part 520

Therefore, under the Federal Food, Drug, and Cosmetic Act and under 
authority delegated to the Commissioner of Food and Drugs and 
redelegated to the Center for Veterinary Medicine, 21 CFR part 520 is 
amended as follows:
