Sodium sulfacetamide is a sulfonamide with antibacterial activity while sulfur acts as a keratolytic agent. Chemically sodium sulfacetamide is N-[(4-aminophenyl) sulfonyl]-acetamide, monosodium salt, monohydrate. The structural formula is:
Each gram of Sodium Sulfacetamide 9% - Sulfur 4% Wash contains 90 mg of Sodium Sulfacetamide and 45 mg of Sulfur in a formulation containing: purified water, sodium cocoyl isethionate, magnesium aluminum silicate, disodium oleamido MEA sulfosuccinate, sodium methyl cocoyl taurate, glyceryl stearate (and) PEG-100 stearate, stearyl alcohol, cetyl alcohol, methyl paraben, propyl paraben, butylated hydroxytoluene, xanthan gum, sodium thiosulfate, green tea extract, aloe vera, disodium EDTA, and fragrance.
CLINICAL PHARMACOLOGY: The most widely accepted mechanism of action of sulfonamides is the Woods-Fildes theory, which is based on the fact that sulfonamides act as competitive antagonists to para-aminobenzoic acid (PABA), an essential component for bacterial growth. While absorption through intact skin has not been determined, sodium sulfacetamide is readily absorbed from the gastrointestinal tract when taken orally and excreted in the urine, largely unchanged. The biological half-life has variously been reported as 7 to 12.8 hours. The exact mode of action of sulfur in the treatment of acne is not known, but it has been reported that it inhibits the growth of Propionibacterium acnes and the formation of free fatty acids.
