Sulfanilamide preparation for external use. Has a broad spectrum of antibacterial action, which includes virtually all Gram-positive and Gram-negative microorganisms, including Pseudomonas aeruginosa, Escherichia coli, Proteus spp., Staphytococcus spp., Streptococcus spp., Enteiobacter spp. and Klebsiella spp., some species of fungi and yeast are also sensitive to it.
When applied to damaged skin, it dissociates with the release of silver and sulphanilamide ions, interacts with the sulfhydryl groups of the enzymes of the bacterial cell and reduces their activity, while at the same time it does not have a damaging effect on tissue cells. Penetrates into a necrotic tissue. It acts bacteriostatically.
