Used primarily in veterinary medicine, especially in livestock. Effective against respiratory infections in cattle, sheep, and pigs caused by bacteria like Mannheimia haemolytica, Pasteurella multocida, and Mycoplasma species. Administered as a single injection due to its long-acting properties, reducing labor and stress in animals. Commonly used in feedlot operations to control bovine respiratory disease (BRD). Also used in poultry to treat mycoplasma infections that affect respiratory health and productivity. Its formulation allows for sustained release, maintaining effective drug levels over several days. Not approved for use in animals producing milk for human consumption due to residue concerns.
