Silver Sulphadiazine USP
Silver Sulphadiazine USP is a topical antimicrobial agent used primarily in the treatment and prevention of infections in burn wounds and other skin injuries. It combines the broad-spectrum antibacterial effects of silver ions with the antimicrobial properties of sulphadiazine, a sulfonamide antibiotic. This combination helps to prevent bacterial colonization and promotes healing by reducing the risk of infection. Silver Sulphadiazine is widely used in clinical and hospital settings and is available as a cream or ointment formulation meeting United States Pharmacopeia (USP) standards for purity and quality.
