21 CFR Parts 522 and 556
Implantation or Injectable Dosage Form New Animal Drugs; Flunixin
Meglumine
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 Schering-Plough Animal Health Corp. The
supplemental NADA provides for veterinary prescription use of flunixin
meglumine solution, intravenously, for control of pyrexia associated
with bovine respiratory disease and endotoxemia, and control of
inflammation in endotoxemia, in beef and nonlactating dairy cattle.
EFFECTIVE DATE: July 20, 1998.
FOR FURTHER INFORMATION CONTACT: Estella Z. Jones, Center for
Veterinary Medicine (HFV-135), Food and Drug Administration, 7500
Standish Pl., Rockville, MD 20855, 301-594-1643.
SUPPLEMENTARY INFORMATION: Schering-Plough Animal Health Corp., 1095
Morris Ave., P.O. Box 3182, Union, NJ 07083-1982, is sponsor of NADA
101-479 Banamine (flunixin meglumine) Injectable Solution
that provides for veterinary prescription use of flunixin meglumine,
intravenously or intramuscularly, for alleviation of inflammation and
pain associated with musculoskeletal disorders, and alleviation of
visceral pain associated with colic in the horse. The sponsor filed a
supplemental NADA that provides for veterinary prescription use of
flunixin meglumine solution, intravenously, for control of pyrexia
associated with bovine respiratory disease and endotoxemia, and control
of inflammation in endotoxemia, in beef cattle and nonlactating dairy
cattle. The supplemental NADA is approved as of May 6, 1998, and the
regulations are amended in 21 CFR 522.970 by revising paragraph (b), by
redesignating existing paragraph (c) as (d), by revising newly
redesignated paragraph (d), and by adding paragraph (c) to reflect the
approval. The basis for approval is discussed in the freedom of
information summary.
In addition, a tolerance for residues of flunixin meglumine in
edible tissues of cattle has not been previously established. Section
556.286 is added to provide tolerances for flunixin meglumine residues
in cattle liver (target tissue) and in cattle muscle.
Also, in addition to codifying a tolerance for flunixin residues in
cattle tissues, FDA is amending the regulation to codify the acceptable
daily intake (ADI) for total residues of flunixin. The ADI is the
amount of total drug residue that can be consumed by humans every day.
Previously, FDA had codified safe concentrations which represent the
ADI corrected for consumption. The safe concentrations were confusing
because few individuals understood the relationship between safe
concentrations, a value representing total residues, and tolerance, the
part of the drug residue in a given tissue that is detected by an
analytical method. To eliminate this confusion, FDA is codifying the
ADI.
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
for beef cattle and nonlactating dairy cattle qualifies for 3 years of
marketing exclusivity beginning May 6, 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 approval and conducted or sponsored by
the applicant. Three years marketing exclusivity is limited to use of
the drug for the control of pyrexia associated with bovine respiratory
disease and endotoxemia, and control of inflammation in endotoxemia, in
beef cattle and nonlactating dairy cattle.
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.
The agency has carefully considered the potential environmental
effects of this action. FDA has concluded that the action will not have
a significant impact on the human environment, and that an
environmental impact statement is not required. The agency's finding of
no significant impact and the evidence supporting that finding,
contained in an environmental assessment, may be seen in the Dockets
Management Branch (address above) between 9 a.m. and 4 p.m., Monday
through Friday.

Therefore, under the Federal Food, Drug, and Cosmetic Act and under
authority delegated to the Commissioner of Food and Drugs and
redelegated to the Center for Veterinary Medicine, 21 CFR parts 522 and
556 are amended as follows:
PART 522--IMPLANTATION OR INJECTABLE DOSAGE FORM NEW ANIMAL DRUGS
