Sodium Sulfacetamide and Sulfur Suspension Description

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 contains 90 mg of sodium sulfacetamide and 42.5 mg of sulfur in vehicle consisting of aloe vera gel, ammonium lauryl sulfate, butylated hydroxytoluene, cetyl alcohol, cocamidopropyl betaine, disodium EDTA, glycerin, glyceryl stearate SE, green tea extract, guar gum, methylparaben, PEG 100 stearate, propylene glycol, propylparaben, purified water, sodium thiosulfate, stearyl alcohol, and triacetin.

Sodium Sulfacetamide and Sulfur Suspension - Clinical Pharmacology

Sodium sulfacetamide exerts a bacteriostatic effect against sulfonamide sensitive Gram-positive and Gram-negative microorganisms commonly isolated from secondary cutaneous pyogenic infections. It acts by restricting the synthesis of folic acid required by bacteria for growth, by its competition with para-aminobenzoic acid. There is no clinical data available on the degree and rate of systemic absorption of this product when applied to the skin or scalp. However, significant absorption of sodium sulfacetamide through the skin has been reported.

The following in vitro data is available but the clinical significance is unknown. Organisms that show susceptibility to sodium sulfacetamide are: Streptococci, Staphylococci, E. coli, Klebsiella pneumoniae, Pseudomonas pyocyanea, Salmonella species, Proteus vulgaris, Nocardia and Actinomyces.

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

Sodium Sulfacetamide 9% and Sulfur 4.25% Suspension is indicated in the topical control of acne vulgaris, acne rosacea and seborrheic dermatitis.

Contraindications

Sodium Sulfacetamide 9% and Sulfur 4.25% Suspension is contraindicated for use by patients having known hypersensitivity to sulfonamides, sulfur or any other component of this preparation. Clenia Plus is 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.

Sulfonamides are known to cause Stevens-Johnson syndrome in hypersensitive individuals. Stevens-Johnson syndrome also has been reported following the use of sodium sulfacetamide topically. Cases of drug-induced systemic lupus erythematosus from topical sulfacetamide also have been reported. In one of these cases, there was a fatal outcome.

FOR EXTERNAL USE ONLY. NOT FOR OPHTHALMIC USE. Avoid contact with eyes, lips and mucous membranes.

KEEP OUT OF REACH OF CHILDREN. Keep container tightly closed.

Precautions

General

Nonsusceptible organisms, including fungi, may proliferate with the use of this preparation. 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. Systemic absorption of topical sulfonamides is greater following application to large, infected, abraded, denuded or severely burned areas. Under these circumstances, any of the adverse effects produced by the systemic administration of these agents could potentially occur, and appropriate observations and laboratory determinations should be performed.

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

Information for patients

Avoid contact with eyes, lips and mucous membranes. Patients should discontinue the use of this product if the condition becomes worse or if a rash develops in the area being treated or elsewhere. The use of this product should also be discontinued promptly and the physician notified if any arthritis, fever or sores in the mouth develop.

Drug Interactions

This product is incompatible with silver preparations.

Carcinogenesis, Mutagenesis and Impairment of Fertility

Long-term studies in animals have not been performed to evaluate carcinogenic potential. Studies on reproduction and fertility also have not been performed. Chromosomal nondisjunction has been reported in the yeast, Saccharomyces cerevisiae, following application of sodium sulfacetamide. The significance of this finding to the topical use of sodium sulfacetamide in the human is unknown.

PREGNANCY

Category C

Animal reproduction studies have not been conducted with Sodium Sulfacetamide 9% and Sulfur 4.25% Suspension. It is not known whether Sodium Sulfacetamide 9% and Sulfur 4.25% Suspension can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Clenia Plus should be given to a pregnant woman only if clearly needed or when potential benefits outweigh potential hazards to the fetus.

NURSING MOTHERS

It is not known whether this drug is excreted in the human milk. 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 Sodium Sulfacetamide 9% and Sulfur 4.25% Suspension is administered to a nursing woman.

PEDIATRIC USE

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

Adverse Reactions

Reports of irritation and hypersensitivity to sodium sulfacetamide are uncommon. The following adverse reactions, reported after administration of sterile ophthalmic sodium sulfacetamide, are noteworthy: instances of Stevens-Johnson syndrome and instances of local hypersensitivity which progressed to a syndrome resembling systemic lupus erythematosus; in one case a fatal outcome was reported (see WARNINGS).

Call your doctor for medical advice about side effects. To report SUSPECTED ADVERSE REACTIONS or obtain product information, contact Scite Pharma, LLC at 1-866-633-9033 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

Overdosage

The oral LD 50 of sulfacetamide in mice is 16.5 g/kg. In the event of overdosage, emergency treatment should be started immediately.

Manifestations

Overdosage may cause nausea and vomiting. Large oral overdosage may cause hematuria, crystalluria and renal shutdown due to the precipitation of sulfa crystals in the renal tubules and the urinary tract. For treatment, contact your local Poison Control Center (1-800-222-1222), or your doctor.
