sulfadiazine.
This active agent has the following structural formula:
Silver sulfadiazine cream contains 1% w/w silver sulfadiazine. The
vehicle in which the
active ingredient is dispersed consists of water, stearyl alcohol,
white petrolatum,
polyoxyl 40 stearate, propylene glycol, isopropyl myristate, and
sorbitan monooleate
with 0.3% methylparaben as a preservative.
CLINICAL PHARMACOLOGY
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 membrane and cell wall to produce its bactericidal
effect.
