21 CFR Parts 522 and 556


New Animal Drugs; Enrofloxacin

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 Bayer HealthCare LLC. The supplemental NADA 
provides for use of enrofloxacin injectable solution in swine for the 
treatment and control of respiratory disease.

DATES: This rule is effective April 23, 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: 
[email protected].

SUPPLEMENTARY INFORMATION: Bayer HealthCare LLC, Animal Health 
Division, P.O. Box 390, Shawnee Mission, KS 66201, filed a supplement 
to NADA 141-068 for BAYTRIL 100 (enrofloxacin) injectable solution. The 
supplemental NADA provides for use of enrofloxacin injectable solution 
in swine for the treatment and control of swine respiratory disease 
(SRD) associated with Actinobacillus pleuropneumoniae, Pasteurella 
multocida, Haemophilus parasuis, and Streptococcus suis. The 
supplemental NADA is approved as of March 14, 2008, and the regulations 
in 21 CFR 522.812 and 556.228 (Sec. Sec.  522.812 and 556.228) are 
amended to reflect the approval.
    In addition, FDA has noticed that Sec.  556.228 is not in 
alphabetical sequence in 21 CFR part 556. At this time, that section is 
being redesignated to correct this error. A conforming change is also 
being made in Sec.  522.812 to reflect the correction in part 556.
    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 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.
    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. The agency has determined under 21 CFR 25.33(d)(5) 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.
