The FDA Issues Final Guidances for Animal Drug Depletion Studies
March 6, 2015
The U.S. Food and Drug Administration issued today two final guidances for industry (GFI) on animal drug depletion studies:
#207, Studies to Evaluate the Metabolism and Residue Kinetics of Veterinary Drugs In Food-Producing Animals: Marker Residue Depletion Studies to Establish Product Withdrawal Periods (建立兽药停药期的标识残留物消除研究)and
#208, Studies to Evaluate the Metabolism and Residue Kinetics of Veterinary Drugs in Food-Producing Animals: Validation of Analytical Methods Used in Residue Depletion Studies(残留物消除研究的分析方法验证).
These guidances provide study design recommendations which will facilitate universal acceptance of the generated residue depletion data to fulfill the national/regional requirements when establishing appropriate withdrawal periods in edible tissues including meat, milk and eggs.
GFIs #207 and #208 support the FDA’s work with the Veterinary International Conference on Harmonization (VICH), an international program aimed at harmonizing technical requirements for veterinary product regulation. These guidances, which are the FDA’s versions of VICH GL48(R) and VICH GL49(R) , respectively, would help ensure that one residue depletion study (per species), conducted within any VICH region, would satisfy the data recommendations for establishment of appropriate withdrawal periods for a specific product in food-producing animals.
