DESCRIPTION
Sodium sulfacetamide is a sulfonamide with antibacterial activity. 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 SSS 10 - 5 Emollient Foam contains 100 mg of Sodium Sulfacetamide and 50 mg of Sulfur in an aqueous based emollient foam vehicle containing: Butane, Butylene Glycol, Cellulose Gum, Ceteareth-20, Cetearyl Alcohol, Dimethicone, Glycerin, Magnesium Aluminum Silicate, Polysorbate 20, Propane, Titanium Dioxide, Water.
CLINICAL PHARMACOLOGY
Sodium sulfacetamide exhibits antibacterial activity. 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 is reported to result from the interaction of sulfur with the cysteine content of keratinocytes. Furthermore, in combination with sulfacetamide, sulfur has been reported to inhibit the growth of Propionibacterium acnes, thereby adding to the product’s antibacterial activity and reducing associated inflammation.

PRECAUTIONS
General
The object of this therapy is to achieve desquamation without irritation, but sodium sulfacetamide and sulfur can cause reddening and scaling of the skin. These side effects are not unusual in the treatment of acne vulgaris, but patients should be cautioned about the possibility. If irritation develops, use of the product should be discontinued and appropriate therapy instituted. Patients should be carefully observed for possible local irritation or sensitization during long-term therapy.
Information for Patients - Avoid contact with eyes, eyelids, lips and mucous membranes. If accidental contact occurs, rinse with water. If excessive irritation develops, discontinue use and consult your physician.
Carcinogenesis, Mutagenesis and Impairment of Fertility
Long-term studies in animals have not been performed to evaluate carcinogenic potential.
Pregnancy
Category C
Animal reproduction studies have not been conducted with SSS 10 - 5 Emollient Foam. When administered to a pregnant woman, it also is not known whether SSS 10 - 5 Emollient Foam can affect reproduction capacity or cause fetal harm. SSS 10 - 5 Emollient Foam should be given to a pregnant woman only if clearly needed.
Nursing Mothers
It is not known whether sodium sulfacetamide is excreted in human milk following topical use of SSS 10 - 5 Emollient Foam. However, small amounts of orally administered sulfonamides have been reported to be eliminated in human milk. Because many drugs are excreted in human milk, caution should be exercised when SSS 10 - 5 Emollient Foam is administered to a nursing woman.
DOSAGE AND ADMINISTRATION
Wash affected areas before use, 1 to 2 times daily as directed by physician.
Before each use, shake can vigorously, then gently tap the bottom of the can on a firm surface or in palm of other hand. Tap can 1 - 2 times, then shake and tap again. Dispense can upright.
