II. TARGET ANIMAL SAFETY AND DRUG EFFECTIVENESS:

In accordance with the Center's policy letter dated November 2, 1989, as published in the Federal Register on January 30, 1990 (55 FR 3107), following the approval of an ANADA for a generic Type A medicated article (ANADA 200-075; generic salinomycin sodium), Hoechst-Roussel Agri-Vet Company is entitled to the approval of generic salinomycin in combination with bambermycins. Bioequivalence studies are not required for the approval of this generic combination (Type C medicated feed). Salinomycin sodium is codified under 21 CFR § 558.550. Bambermycins is codified under 21 CFR § 558.95. The combination of salinomycin sodium and bambermycins is codified under 21 CFR § 558.95Co)(1)(xii).

 

III. HUMAN FOOD SAFETY:

In accordance with the Centers policy letter dated November 2, 1989, as published in the Federal Register on January 30, 1990 (55 FR 3107), tissue residue studies are not required for the approval of this generic combination (Type C medicated feed).

  1. Tolerances for Residues
    The tolerance established for the pioneer salinomycin sodium product applies to the generic salinomycin sodium product. The safe concentrations for total salinomycin residues in the uncooked edible tissues of broiler chickens were established as 0.6 ppm in muscle, 1.8 ppm in liver, and 1.2 ppm in skin/fat.

    Bambermycins has a no-tolerance clearance as published in 40 FR 59726 (December 30, 1975). The safe concentration for total bambermycins residues in the uncooked edible tissues of broiler chickens were established in NADA 44-759 (38 FR 1274; January 11, 1973).

  2. Withdrawal Time
    Based on the information in 21 CFR § 558.95(b)(1)(xii), a 0-day withdrawal time is required for the combination ofbambermycins and salinomycin.
  3. Regulatory Method for Residues
    A regulatory method for salinomycin was not required because residue levels in all three broiler tissues (muscle, liver, and skin/fat) were significantly below the established safe concentration for total residues.

    A microbiological assay method is used to assay tissues for bambermycins residues. The method entitled "Quantitative Agar Well Plate Assay of Bambermycins (Flavomycin) in Organs and Tissues" is on file at the Center for Veterinary Medicine, Food and Drug Administration, 7500 Standish Pl., Rockville, MD 20855.

 

IV. AGENCY CONCLUSIONS:

This ANADA submitted under section 512(b) of the Federal Food, Drug, and Cosmetic Act satisfies the requirements of section 512(n) of the act and demonstrates that the combination of salinomycin sodium and bambermycins when used under its proposed conditions of use, is safe and effective for its labeled indications.
