Used as a long-acting sulfonamide antibiotic in veterinary medicine, particularly for the treatment of bacterial infections in livestock. It is effective against a range of gram-positive and gram-negative bacteria. Due to its slow absorption and prolonged presence in the body, it allows for less frequent dosing, making it practical for use in farm animals. Commonly administered to cattle, pigs, and poultry to manage respiratory, urinary, and gastrointestinal tract infections. Its use in food-producing animals is regulated due to concerns about residual levels in meat and milk.
