Used primarily as an antibacterial agent, especially in topical formulations for skin infections. It works by inhibiting bacterial growth and is often combined with other sulfonamides or antimicrobials to enhance effectiveness. Commonly found in creams and ointments for treating acne, wounds, and minor burns due to its ability to prevent infection in damaged skin. Also used in some veterinary applications for treating bacterial infections in animals. Its low systemic absorption makes it suitable for localized treatment with minimal risk of widespread side effects.
