21 CFR Part 558

[Docket No. FDA-2009-N-0665]


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

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule; technical amendment.

-----------------------------------------------------------------------

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. The supplemental NADA 
provides for use of two-way combination Type B and C medicated swine 
feeds formulated with ractopamine hydrochloride and tylosin phosphate 
following use of tylosin tartrate medicated drinking water consistent 
with the sequential use approved for single-ingredient tylosin 
medicated swine feed.

DATES:  This rule is effective December 17, 2009.

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: [email protected].

SUPPLEMENTARY INFORMATION: Elanco Animal Health, a Div. of Eli Lilly & 
Co., Lilly Corporate Center, Indianapolis, IN 46285, filed a supplement 
to NADA 141-172 for use of two-way combination Type B and C medicated 
swine feeds formulated with PAYLEAN (ractopamine hydrochloride) and 
TYLAN (tylosin phosphate) single-ingredient Type A medicated articles. 
The supplement provides use of two-way combination Type B and C 
medicated swine feeds formulated with ractopamine hydrochloride and 
tylosin phosphate following use of tylosin tartrate medicated drinking 
water consistent with the sequential use approved for single-ingredient 
tylosin medicated swine feed (73 FR 76946, December 18, 2008). The 
supplemental NADA is approved as of October 23, 2009, and the 
regulations in 21 CFR 558.500 are amended to reflect the approval.
    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.
    In addition, FDA has noticed that the tylosin levels for single-
ingredient Type C medicated swine feed are not clearly described in 21 
CFR 558.625. At this time, those regulations are being revised to 
clarify this use of levels. This action is being taken to improve the 
accuracy of the regulations.
    FDA has determined under 21 CFR 25.33 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.
