NPB Approval gives Aivlosin WSG the broadest label indication of any product for the control of swine respiratory disease. Feb 02, 2021 In January 2021, the FDA’s Center for Veterinary Medicine, as well as the Veterinary Drugs Directorate of Health Canada, added Mycoplasma hyopneumoniae to the approved label indications for Aivlosin ( tylvalosin) Water Soluble Granules (WSG). “This approval gives Aivlosin WSG the broadest label indication of any product for the control of swine respiratory disease (SRD),” said Dr. Chad Smith, U.S. technical service veterinarian for Pharmgate. “ M. hyo is a primary pathogen in swine respiratory disease complexes and plays an important role in facilitating the entry of bacterial and viral pathogens. Aivlosin WSG is competitive economically compared to other protocols on a per-pig basis. Veterinarians and producers can be confident they are making a responsible antibiotic choice to control SRD.”
