21 CFR Part 520


Oral Dosage Form New Animal Drugs; Ivermectin Liquid

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 an abbreviated new animal drug 
application (ANADA) filed by First Priority, Inc. The ANADA provides 
for oral use of ivermectin solution in horses for the treatment and 
control of various species of internal and cutaneous parasites.

DATES: This rule is effective December 5, 2001.

FOR FURTHER INFORMATION CONTACT: Lonnie W. Luther, Center for 
Veterinary Medicine (HFV-102), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-827-0209.

SUPPLEMENTARY INFORMATION: First Priority, Inc., 1585 Todd Farm Dr., 
Elgin, IL 60123, filed ANADA 200-321 for PRIMECTINTM 
(ivermectin) Equine Oral Liquid. The application provides for oral use 
of a 1.0 percent ivermectin solution in horses for the treatment and 
control of various species of gastrointestinal nematodes, lungworms, 
stomach bots, and cutaneous larvae and microfilariae. First Priority's 
PRIMECTINTM Equine Oral Liquid is approved as a generic copy 
of Merial Ltd.'s EQVALAN (ivermectin) Oral Liquid for Horses, 
approved under NADA 140-439. ANADA 200-321 is approved as of September 
7, 2001, and 21 CFR 520.1195 is amended 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 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.
    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 congressional review requirements in 5 
U.S.C. 801-808.
