FDA Wants Antimicrobials Input
FDA is looking for public input on its efforts to mitigate antimicrobial resistance by focusing for the first time on medically important antimicrobials used to treat human disease that are placed in animal feed or water that have at least one therapeutic indication without a defined duration of use. A statement says the agency wants information from the public about how to establish appropriately targeted durations of use for the estimated 32% of therapeutic products affected by a 12/2013 guidance that, when fully implemented, limits use of the drugs to therapeutic-only use under the oversight of a veterinarian. The duration of use information is needed to foster stewardship of medically important antimicrobial drugs in food-producing animals and help preserve the effectiveness of these antimicrobials in animal and human medicine, FDA says. Specifically, the statement says, for certain species and disease indications as listed in a still to be released Federal Register notice, the agency wants to obtain information on:
- the underlying diseases requiring the drugs for therapeutic purposes, and periods when livestock or poultry are at risk for developing the diseases;
- more targeted antimicrobial use regimens for the diseases and husbandry practices that may help avoid the need for the antimicrobials, or that may help make more targeted antimicrobial use regimens more effective; and
- strategies for updating affected labeling of drug products that do not currently included a defined duration of use.
