Sulfamethazine sodium salt is widely used in veterinary medicine as an antimicrobial agent to treat and prevent bacterial infections in livestock, particularly in cattle, swine, and poultry. It is effective against a range of Gram-positive and Gram-negative bacteria, making it valuable for managing respiratory, gastrointestinal, and urinary tract infections. Additionally, it is often incorporated into animal feed or drinking water to promote growth and improve overall health. In aquaculture, it is utilized to control bacterial diseases in fish and other aquatic species. Its water-soluble nature allows for easy administration and rapid absorption in animals. However, its use is regulated in many countries to prevent antibiotic resistance and ensure food safety.
