Other reviews of the evidence have also concluded, "[the] quality of the trials was limited". Cochrane has raised concerns about delays in time to wound healing when SSD is used. In addition to concerns regarding delayed wound healing, silver sulfadiazine is associated with sloughing of the wound surface that makes reassessment of wound depth difficult, and requires daily reapplication. For this reason, application of silver sulfadiazine is not recommended for most burns due to altered wound appearance and the frequency of required dressing changes. Adverse effects
A noninfection-related clear fluid may form on the wounds surface. Burning and painful sensations are not uncommon, but are only temporary. Application to large areas or to severe burns may lead to systemic absorption and lead to adverse effects similar to those of other sulfonamides. About 0.1 to 1.0% of people show hypersensitivity reactions such as rashes or erythema multiforme. This reaction is known from other sulfonamides including antibacterials, thiazide diuretics, and sulfonylurea antidiabetics; but data on the likelihood of cross-allergies are inconsistent. Incorporation of the silver ions can lead to local argyria (discoloration of the skin), especially if the treated area is exposed to ultraviolet light. Generalised argyria with silver accumulation in kidneys, liver, and retina has only been found in association with excessive long-term use, or repeated use on severe and heavily inflamed burns. Possible consequences of generalised argyria include interstitial nephritis and anemia.
Interactions
Proteases such as trypsin and clostridiopeptidase, which are contained in ointments used for the removal of dead skin on wounds, can be inhibited by silver ions if applied simultaneously. When silver sulfadiazine is absorbed in significant amounts, it can increase effects and side effects of some drugs such as vitamin K antagonists. Pharmacokinetics
The chemical is poorly soluble, and has only very limited penetration through intact skin. However, contact with body fluids produces free sulfadiazine which can then be systemically absorbed and distributed; it undergoes glucuronidation in the liver and is also excreted unaltered in urine. Only when applied to large-area (especially second- and third-degree) burns or other lesions is absorption into the body a problem. Names
Brand names include Silvadene (a genericized trademark), Silverex, Silverol, Silveleb, Silvazine, Flamazine, Thermazene, BurnHeal, Silvozin Tulle Dressing and SSD. See also
