Used primarily as an antibacterial agent in veterinary medicine, especially in the treatment of bacterial infections in livestock and poultry. It helps control diseases caused by susceptible microorganisms, including certain respiratory and enteric infections. Due to its solubility and stability, it can be administered through drinking water or feed. Its use is limited in human medicine but remains relevant in animal health for prophylaxis and therapy under veterinary supervision. Resistance and residue concerns have led to regulated use in food-producing animals.
