Resumen

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of an original new animal drug application (NADA) filed by Merial Ltd. The NADA provides for the veterinary prescription use of eprinomectin by injection for the treatment and control of internal and external parasites of cattle on pasture with persistent effectiveness. The current tolerance for the marker residue for total residues of eprinomectin in edible tissues of cattle is being lowered. The method of detection for residues of the carcinogenic excipient n-methyl-2- pyrrolidone (NMP) in edible tissues of cattle is also being codified.
