Under the provisions of the Federal Food, Drug, and Cosmetic Act, as amended by the Generic Animal Drug and Patent Term Restoration Act, (53 FR 50460, December 15, 1988, First GADPTRA Policy Letter) an abbreviated new animal drug application (ANADA) may be submitted for a generic version of an approved new animal drug (pioneer product). New target animal safety data and drug effectiveness data, were not required for approval of this ANADA. This ANADA relies on the target animal safety and drug effectiveness data in the pioneer's new animal drug application. Ordinarily, the ANADA sponsor shows that the generic product is bioequivalent to the pioneer. Bioequivalence is usually demonstrated through a clinical end-point study.

For certain dosage forms, the agency will grant a waiver from conducting an in vivo bioequivalence study (55 FR 24645, June 18, 1990; Fifth GADPTRA Policy Letter; Bioequivalence Guideline, April 1990). Based upon the formulation characteristics of the generic product, AgriLabs, Ltd. was granted a waiver from conducting an in vivo bioequivalence study for gentamicin sulfate solution. The generic and pioneer products are solutions with the same active and inactive ingredients. The generic and pioneer products also contain the same concentration of active ingredient. This ANADA was granted a waiver January 3, 1990 (see attachment).


Data on human safety, pertaining to consumption of drug residues in food, were not required for approval of this ANADA. This drug is labeled for use in horses not intended for food.


This ANADA satisfies the requirements of section 512 of the Act and demonstrates that gentamicin sulfate solution, when used under its proposed conditions of use, is safe and effective for its labeled indications.
