is a topical sulfonamide/silver antibacterial used as a topical burn cream on burns, including chemical burns. It prevents the growth of a wide array of bacteria, as well as yeast, on the damaged skin. Studies have found that increases healing times; and it is therefore not recommended by the authors of a Cochrane review. An aseptic exudate may form on the wound's surface. Burning and painful sensations are not uncommon but only temporary. This is a reaction known from other sulfonamides including antibacterials, thiazide diuretics, and sulfonylurea antidiabetics; but data on the likelihood of cross-allergies are inconsistent. Silver Sulfadiazine is a kind of API.
