Food and Drug Administration

21 CFR Parts 522 and 556


Implantation or Injectable Dosage Form New Animal Drugs; 
Ceftiofur Hydrochloride Sterile Suspension

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 (NADA's) filed by Pharmacia & Upjohn Co. One 
supplemental NADA provides for veterinary prescription use of ceftiofur 
hydrochloride sterile suspension for intramuscular or subcutaneous 
injection in cattle for treatment of bovine respiratory disease and 
acute bovine interdigital necrobacillosis. The second supplemental NADA 
provides for a revised label warning against use in veal calves.

EFFECTIVE DATE: October 6, 1998.

FOR FURTHER INFORMATION CONTACT: Naba K. Das, Center for Veterinary 
Medicine (HFV-133), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 301-594-1659.

SUPPLEMENTARY INFORMATION: Pharmacia & Upjohn Co., 7000 Portage Rd., 
Kalamazoo, MI 49001-0199, filed two supplements to NADA 140-890. One 
supplement provides for veterinary prescription use of 
Excenel (ceftiofur hydrochloride) Sterile Suspension for 
intramuscular or subcutaneous injection in cattle for treatment of 
bovine respiratory disease (BRD, shipping fever, pneumonia) associated 
with Pasteurella haemolytica, P. multocida, and Haemophilus somnus and 
acute bovine interdigital necrobacillosis (foot rot, pododermatitis) 
associated with Fusobacterium necrophorum and Bacteroides 
melaninogenicus. This supplemental NADA is approved as of July 26, 
1998. The second supplemental NADA provides for a revised label warning 
against use in veal calves and is approved as of August 18, 1998. The 
regulation is amended in 21 CFR part 522.314 to reflect the approvals. 
The basis for approval is discussed in the freedom of information 
summary.
    In addition, due to injection site residues following subcutaneous 
use of this product in cattle, 21 CFR 556.113 is amended to establish 
tolerances for residues of ceftiofur in edible tissues of treated 
cattle. Also, the regulation is amended to establish an acceptable 
daily intake (ADI) for total ceftiofur residues. The ADI represents the 
total amount of drug residue that can safely be consumed by humans 
every day.
    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.
    Under 21 U.S.C. 360b(c)(2)(F)(iii), this approval for food 
producing animals qualifies for 3 years of marketing exclusivity 
beginning July 26, 1998, because the supplemental application contains 
substantial evidence of the effectiveness of the drug involved, any 
studies of animal safety, or, in the case of food producing animals, 
human food safety studies (other than bioequivalence or residue 
studies) required for the approval of the supplement and conducted or 
sponsored by the applicant. The 3 years of marketing exclusivity 
applies only to the new species (cattle) for which the supplemental 
application is approved.
    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.

5 consecutive days. In addition, for bovine respiratory disease, 
administer 2.2 milligrams per kilogram (1.0 milligram per pound) of 
body weight every other day on days 1 and 3 (48-hour interval).
    (ii) Indications for use. For treatment of bovine respiratory 
disease (BRD, shipping fever, pneumonia) associated with Pasteurella 
haemolytica, P. multocida, and Haemophilus somnus and acute bovine 
interdigital necrobacillosis (foot rot, pododermatitis) associated with 
Fusobacterium necrophorum and Bacteroides melaninogenicus.
     (iii) Limitations. For intramuscular or subcutaneous use only. Do 
not inject more than 15 milliliters at each intramuscular injection 
site. Do not slaughter treated cattle for 48 hours (2 days) after last

per million in kidney (target tissue), 2 parts per million in the 
liver, 1 part per million in muscle, and 100 parts per billion in milk.
