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 pad of Sumaxin® (sodium sulfacetamide 10% & sulfur 4%) Cleansing Pads is coated with a cleanser-based formulation. Each gram of this cleanser-based formulation contains 100 mg of Sodium Sulfacetamide and 40 mg of Sulfur. The cleanser base consists of: aloe, butylated hydroxytoluene, cetyl alcohol, disodium oleamido MEA sulfosuccinate, edetate disodium, fragrance, glycerin, glyceryl stearate/PEG-100 stearate, green tea, methylparaben, propylparaben, purified water, sodium cocoyl isethionate, sodium lauryl sulfoacetate, sodium thiosulfate, stearyl alcohol.

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 unknown, but it has been reported that it inhibits the growth of Propionibacterium acnes and the formation of free fatty acids.

Sumaxin® (sodium sulfacetamide 10% & sulfur 4%) Cleansing Pads are available in boxes of 60 cloths (3.7 g), NDC 43538-100-60.

Although rare, sensitivity to sodium sulfacetamide 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.
