CLINICAL PHARMACOLOGY
MECHANISM OF ACTION:
The mechanism of action of Mafenide is not known, but is different
from that of the
sulfonamides. Mafenide is not antagonized by pABA, serum, pus or
tissue exudates, and
there is no correlation between bacterial sensitivities to mafenide
and to the
sulfonamides. Its activity is not altered by changes in the acidity of
the environment. The
osmolality of the 5% topical solution is approximately 340 mOsm/kg.
ABSORPTION AND METABOLISM:
Applied topically, Mafenide Acetate diffuses through devascularized
areas. Approximately
80% of a Mafenide Acetate dose is delivered to burned tissue over four
hours following
topical application of the 5% solution. Following application of
Mafenide Acetate cream
and solution, peak Mafenide concentrations in human burned skin tissue
occur at two
and four hours, respectively. Peak tissue concentrations are similar
