Food and Drug Administration

21 CFR Part 558

 
New Animal Drugs For Use in Animal Feeds; 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 supplemental new animal drug 
application (NADA) filed by Elanco Animal Health, A Division of Eli 
Lilly & Co. The supplemental NADA provides for revision of an 
effectiveness claim and pathogen nomenclature for a tylosin phosphate 
and sulfamethazine Type A medicated article used to manufacture 
medicated swine feeds.

DATES: This rule is effective June 17, 2008.

FOR FURTHER INFORMATION CONTACT: Timothy Schell, Center for Veterinary 
Medicine (HFV-128), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 240-276-8116, e-mail: timothy.schell@fda.hhs.gov.

SUPPLEMENTARY INFORMATION: Elanco Animal Health, A Division of Eli 
Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filed a 
supplement to NADA 41-275 that provides for use of TYLAN 40 SULFA-G 
(tylosin phosphate and sulfamethazine) Elliptical Pellets, a Type A 
medicated article. The

[[Page 34185]]

supplement provides for revision of an effectiveness claim and pathogen 
nomenclature. The supplemental NADA is approved as of May 8, 2008, and 
the regulations in 21 CFR 558.630 are amended to reflect the approval.
    Approval of this supplemental NADA did not require review of 
additional safety or effectiveness data or information. Therefore, a 
freedom of information summary is not required.
    FDA 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.

    (1) Amount per ton. 100 grams tylosin and 100 grams sulfamethazine.
    (2) Indications for use-(i) Maintaining weight gains and feed 
efficiency in the presence of atrophic rhinitis; lowering the incidence 
and severity of Bordetella bronchiseptica rhinitis; prevention of swine 
dysentery (vibrionic); control of swine pneumonias caused by bacterial 
pathogens (Pasteurella multocida and/or Corynebacterium pyogenes); for 
reducing the incidence of cervical lymphadenitis (jowl abscesses) 
caused by Group E Streptococci. Only the sulfamethazine portion of this 
combination is active in controlling jowl abscesses.
