| CLINICAL PHARMACOLOGY
SULFAMYLON Cream, applied topically, produces a marked reduction in the bacterial population present in the avascular tissues of second- and third-degree burns. Reduction in bacterial growth after application of SULFAMYLON Cream has also been reported to permit spontaneous healing of deep partial-thickness burns, and thus prevent conversion of burn wounds from partial-thickness to full-thickness. It should be noted, however, that delayed eschar separation has occurred in some cases.
Absorption and Metabolism
INDICATIONS AND USAGE
Contains sodium metabisulfite, a sulfite that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low. Sulfite sensitivity is seen more frequently in asthmatic than in nonasthmatic people
| Silver sulfadiazine has broad antimicrobial activity. It is bactericidal for many gram-negative and gram-positive bacteria as well as being effective against yeast. Results from in vitro testing are listed below. Sufficient data have been obtained to demonstrate that silver sulfadiazine will inhibit bacteria that are resistant to other antimicrobial agents and that the compound is superior to sulfadiazine. Studies utilizing radioactive micronized silver sulfadiazine, electron microscopy, and biochemical techniques have revealed that the mechanism of action of silver sulfadiazine on bacteria differs from silver nitrate and sodium sulfadiazine. Silver sulfadiazine acts only on the cell wall to produce its bactericidal effect.
INDICATIONS AND USAGE
Because sulfonamide therapy is known to increase the possibility of kernicterus, SILVADENE Cream 1% should not be used on pregnant women approaching or at term, on premature infants, or on newborn infants during the first 2 months of life.
Fungal proliferation in and below the eschar may occur. However, the incidence of clinically reported fungal superinfection is low.
The use of SILVADENE Cream 1% (silver sulfadiazine) in some cases of glucose-6-phosphate dehydrogenase-deficient individuals may be hazardous, as hemolysis may occur.
