Used as a sulfonamide antibiotic in veterinary medicine, particularly in the treatment of bacterial infections in livestock. It helps control infections caused by susceptible strains of bacteria in animals such as cattle, swine, and poultry. Commonly administered to prevent or treat gastrointestinal and respiratory tract infections. Its use is regulated due to concerns over antibiotic residues and development of microbial resistance. Often found in combination with other sulfonamides or antimicrobial agents to enhance effectiveness. Not generally used in human medicine.
