New Animal Drugs; 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 two supplemental new animal 
drug applications (NADAs) filed by Elanco Animal Health. The 
supplemental NADAs provide for use of tylosin tartrate soluble powder 
in drinking water of swine followed by tylosin phosphate in medicated 
swine feed for the treatment and control of swine dysentery and the 
control of porcine proliferative enteropathies.

DATES:  This rule is effective December 18, 2008.

FOR FURTHER INFORMATION CONTACT:  Cindy L. Burnsteel, Center for 
Veterinary Medicine (HFV-130), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 240-276-8341, e-mail:

SUPPLEMENTARY INFORMATION: Elanco Animal Health, A Division of Eli 
Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filed a 
supplement to NADA 12 491 for use of TYLAN (tylosin phosphate) Type A 
medicated article. The supplement provides for use of tylosin tartrate 
in medicated drinking water for swine for 3 to 10 days followed by 
administration of tylosin phosphate in medicated swine feed for 2 to 6 
weeks for the control of porcine proliferative enteropathies (PPE, 
ileitis) associated with Lawsonia intracellularis.
    Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and 
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), this supplemental approval 
qualifies for 3 years of marketing exclusivity beginning on the date of 
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.
    Elanco Animal Health also filed a supplement to NADA 13 076 for use 
of TYLAN (tylosin tartrate) Soluble. The supplement provides for use of 
tylosin tartrate in medicated drinking water for swine for 3 to 10 days 
followed by administration of tylosin phosphate in medicated swine feed 
for 2 to 6 weeks for the treatment and control of swine dysentery 
associated with Brachyspira hyodysenteriae and for the control of 
porcine proliferative enteropathies (PPE, ileitis) associated with 
Lawsonia intracellularis.
    Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and 
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), this supplemental approval 
qualifies for 3 years of marketing exclusivity beginning on the date of 
approval. This period of marketing exclusivity applies only to the 
claim for the control of porcine proliferative enteropathies (PPE, 
ileitis) associated with Lawsonia intracellularis.
    The supplemental NADAs are approved as of November 13, 2008, and 
the regulations in 21 CFR 520.2640 and 558.625 are amended to reflect 
the approval.
    The agency has determined under 21 CFR 25.33(a)(1) that these 
actions are of a type that do 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.
