Tilmicosin phosphate is widely used in veterinary medicine as an antibiotic to treat respiratory infections in cattle and swine. It is particularly effective against pathogens like Pasteurella multocida, Mannheimia haemolytica, and Mycoplasma species, which are common causes of pneumonia in these animals. The compound is administered via injection, providing a prolonged therapeutic effect due to its slow release in the body. It helps reduce mortality rates and improves overall animal health, making it a valuable tool in livestock management. Proper dosage and administration are crucial to avoid potential side effects, antibiotic resistance, and ensure optimal treatment outcomes.
