DEPARTMENT OF HEALTH AND HUMAN SERVICES

Food and Drug Administration

21 CFR Part 558


New Animal Drugs for Use in Animal Feeds; Ractopamine and Tylosin

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 Elanco Animal Health. The NADA provides for 
use of ractopamine and tylosin single-ingredient Type A medicated 
articles to make combination drug Type C medicated feeds used for 
increased rate of weight gain, improved feed efficiency, increased 
carcass leanness, and prevention and/or control of porcine 
proliferative enteropathies (ileitis) in swine.

DATES: This rule is effective April 30, 2001.

FOR FURTHER INFORMATION CONTACT: Charles J. Andres, Center for 
Veterinary Medicine (HFV-128), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-827-1600.

SUPPLEMENTARY INFORMATION: Elanco Animal Health, A Division of 
Eli Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filed 
NADA 141-172 that provides for use of Paylean (9 
grams per pound (g/lb) ractopamine hydrochloride) and 
Tylan (10, 40, or 100 g/lb tylosin phosphate) Type A 
medicated article to make combination drug Type C medicated feeds used 
for increased rate of weight gain, improved feed efficiency, and 
increased carcass leanness, and for prevention and/or control of 
porcine proliferative enteropathies (ileitis) associated with 
Lawsonia intracellularis in swine. The NADA is approved as of 
February 20, 2001, and the regulations are amended in 21 CFR 558.500 
and 558.625 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)(2) 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.

    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 558 is 
amended as follows:
