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 mL of Sodium Sulfacetamide 8% - Sulfur 4% Topical Suspension contains 80 mg of Sodium Sulfacetamide and 40 mg of Sulfur in a formulation containing aloe vera gel, benzyl alcohol, butylated hydroxytoluene, cetyl alcohol, glyceryl monostearate, green tea extract, magnesium aluminum silicate, PEG- 40 stearate, phenoxyethanol, polyethylene glycol 400, polyethylene glycol 150, propylene glycol, purified water, sodium lauryl sulfate, sodium thiosulfate, stearyl alcohol, xanthan gum
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.
Sodium Sulfacetamide 8% - Sulfur 4% Topical Suspension is available in 16 fl oz (473 mL) bottles, NDC 71399-0487-6.
Although rare, sensitivity to sodium sulfacetaminde may occur. Therefore, caution and careful supervision should be observed when prescribing this drug for patients who may be prone to hypersensitivity to topical sulfonamides. Systemic toxic reactions such as agranulocytosis, acute hemolytic anemia, purpura hemorrhagica, drug fever, jaundice and contact dermatitis indicate hypersensitivity to sulfonamides. Particular caution should be employed if areas of denuded or abraded skin are involved.
