Federal Register Final rule: FDA is amending the animal drug regulations to reflect approval of an abbreviated new animal drug application filed by Veterinary Laboratories, Inc. that provides for the use of lincomycin injectable solution in swine for the treatment of infectious arthritis and mycoplasma pneumonia. Additional action is also being taken because FDA did not specify the concentration of lincomycin solution approved under the ANADA in the final rule that published in the 5/14/02 Federal Register.
