Used in veterinary medicine, particularly for treating respiratory infections in cattle and pigs. It is effective against common pathogens like Mannheimia haemolytica, Pasteurella multocida, and Histophilus somni in cattle, and Pasteurella multocida and Mycoplasma hyopneumoniae in swine. Administered as a single injection, it provides long-lasting concentrations in lung tissue, making it highly effective for controlling bovine respiratory disease (BRD) and porcine respiratory disease complex (PRDC). Its prolonged activity reduces the need for repeated dosing, supporting improved animal welfare and farm management.
