Tolerances for Residues
The tolerances established for the pioneer product apply to the generic product. A tolerance of 125 parts per billion (ppb) is established for flunixin free acid residues (the marker residue) in the uncooked edible tissues of the liver (the target tissue), 25 ppb in the muscle, and 2 ppb in milk under 21 CFR 556.286.

Withdrawal Times
Under the CVM Bioequivalence Guidelines, when a generic product is granted a waiver of the in vivo bioequivalence testing, the withdrawal period established for the pioneer product is also assigned to the generic product.

For this reason, a withdrawal period of 4 days has been established for flunixin meglumine in cattle (21 CFR 522.970), and milk that has been taken during treatment and for 36 hours after the last treatment must not be used for food. A withdrawal period has not been established for this product in preruminating calves.

Regulatory Method for Residues
The analytical method for the determination of flunixin meglumine in bovine liver is a high performance liquid chromatography (HPLC) method. The validated methods are on file at the Center for Veterinary Medicine, 7500 Standish Place, Rockville, MD 20855.
