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) filedby 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<Register> (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 fileda 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.
