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:

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

INDICATIONS

AVAR Gel, AVAR Green, AVAR Cleanser, AVAR- e Emollient Cream and AVAR- e Green Cream are indicated in the topical control of acne vulgaris, acne rosacea and seborrheic dermatitis.

CONTRAINDICATIONS

AVAR Gel, AVAR Green, AVAR Cleanser, AVAR- e Emollient Cream and AVAR- e Green Cream are contraindicated for use by patients having known hypersensitivity to sulfonamides, sulfur or any other component of these preparations. AVAR Gel, AVAR Green, AVAR Cleanser, AVAR- e Emollient Cream, and AVAR- e Green Cream are not to be used by patients with kidney disease.

WARNINGS

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.

FOR EXTERNAL USE ONLY. Keep away from eyes. Keep out of the reach of children. Keep containers tightly closed.

PRECAUTIONS

General:    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. The object of this therapy is to achieve desquamation without irritation, but sodium sulfacetamide and sulfur can cause reddening and scaling of epidermis. These side effects are not unusual in the treatment of acne vulgaris, but patients should be cautioned about the possibility.

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 AVAR Gel, AVAR Green, AVAR Cleanser, AVAR- e Emollient Cream, or AVAR- e Green Cream. It is also not known whether AVAR Gel, AVAR Green, AVAR Cleanser, AVAR- e Emollient Cream, or AVAR- e Green Cream can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. AVAR Gel, AVAR Green, AVAR Cleanser, AVAR- e Emollient Cream, and AVAR- e Green Cream should be given to a pregnant woman only if clearly needed.

Nursing Mothers:    It is not known whether sodium sulfacetamide is excreted in the human milk following topical use of AVAR Gel, AVAR Green, AVAR Cleanser, AVAR- e Emollient Cream, or AVAR- e Green Cream. However, small amounts of orally administered sulfonamides have been reported to be eliminated in human milk. In view of this and because many drugs are excreted in human milk, caution should be exercised when AVAR Gel, AVAR Green, AVAR Cleanser, AVAR- e Emollient Cream, or AVAR- e Green Cream are administered to a nursing woman.

Pediatric Use:    Safety and effectiveness in children under the age of 12 have not been established.

ADVERSE REACTIONS

Although rare, sodium sulfacetamide may cause local irritation.
