SALVAX is applied topically and used in the removal of excessive keratin in hyperkeratotic skin disorders. Each gram of SALVAX contains salicylic acid 6% as the active ingredient, and the following inactive ingredients: dimethicone, ethylparaben, glycerin, methylcellulose, methylparaben, phenoxyethanol, polyoxyl 40 stearate, polysorbate 20, polysorbate 80, povidone, propylene glycol, propylparaben, purified water, sodium citrate, sodium hydroxide, stearic acid, and trolamine and as propellants isobutane and propane. Salicylic acid is the 2-hydroxy derivative of benzoic acid having the following chemical structure: Chemical Structure

SALVAX is a topical aid in the removal of excessive keratin in hyperkeratotic skin disorders, including verrucae and the various ichthyoses, keratosis palmaris and plantaris, keratosis pilaris, pityriasis rubra pilaris, and psoriasis. SALVAX is a topical aid in the removal of excessive keratin on dorsal and plantar hyperkeratotic lesions.

Clean and dry affected skin. Then apply SALVAX topically to cover affected skin twice per day, or as directed by a physician. Rub in until completely absorbed. Follow these important directions to ensure proper foaming and maximum delivery of product: Shake canister vigorously before each use. Turn upside down (nozzle down) to dispense. Depress ridged portion of dispenser, as illustrated at right. Figure

SALVAX should not be used in any patient known to be sensitive to salicylic acid or any other listed ingredients.

SALVAX should be used only as directed by a physician and should not be used to treat any condition other than that for which it is prescribed. SALVAX should not be used on any skin area where inflammation or exudation is present as increased absorption may occur. If redness or irritation occurs, discontinue use and consult with prescribing physician. (The following interactions are from a published review and include reports concerning both oral and topical salicylate administration. The relationship of these interactions to the use of SALVAX is not known.) Due to the competition of salicylate with other drugs for binding to serum albumin the following drug interactions may occur: Drug Description of Interaction Tolbutamide; Sulfonylureas Hypoglycemia potentiated Methotrexate Decreases tubular reabsorption; clinical toxicity from methotrexate can result Oral Anticoagulants Increased bleeding Drugs changing salicylate levels by altering renal tubular reabsorption: Drug Description Corticosteroids Decreases plasma salicylate level; tapering doses of steroids may promote salicylism Ammonium Sulfate Increases plasma salicylate level Drugs with complicated interactions with salicylates: Drug Description Heparin Salicylate decreases platelet adhesiveness and interferes with hemostasis in heparin-treated patients Pyrazinamide Inhibits pyrazinamide-induced hyperuricemia Uricosuric Agents Effect of probenecid, sulfinpyrazone and phenylbutazone inhibited The following alterations of laboratory tests have been reported during salicylate therapy: Laboratory Tests Effect of Salicylates Thyroid Function Decreased PBI; increased T 3 uptake Urinary Sugar False negative with glucose oxidase; false positive with Clinitest with high-dose salicylate therapy (2-5 g qd) 5 Hydroxyindole Acetic Acid False negative with fluorometric test Acetone, Ketone Bodies False positive FeCl 3 in Gerhardt reaction; red color persists with boiling 17-OH corticosteroids False reduced values with >4.8 g qd salicylate Vanilmandelic Acid False reduced values Uric Acid May increase or decrease depending on dose Prothrombin Decreased levels; slightly increased prothrombin time Salicylic acid has been shown to be teratogenic in rats and monkeys. It is difficult to extrapolate from oral doses of acetylsalicylic acid used in these studies to topical administration as the oral dose to monkeys may represent 4 times the maximum daily human dose of salicylic acid when applied topically over a large body surface. There are no adequate and well-controlled studies in pregnant women. SALVAX should be used during pregnancy only if the potential benefit justifies the risk to the fetus. It is not known whether topically applied salicylic acid is excreted in human milk. Due to the fact that many drugs are excreted in human milk, caution should be exercised by physicians when administering SALVAX to nursing mothers and nursing mothers should certainly not apply SALVAX to the chest area or any other part of the body with which the nursing child's mouth is likely to come in contact. Because of the potential for serious adverse reactions in nursing infants from the mother's use of SALVAX, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. No data are available concerning potential carcinogenic or reproductive effects of SALVAX. It has been shown to lack mutagenic potential in the Ames Salmonella test.

Transient stinging, burning, itching or irritation is possible. Peeling of the skin may increase as the salicylic acid works to loosen excess keratin. If excessive burning, stinging or peeling occurs, discontinue use and consult your physician.

Salicylic acid has been shown to produce desquamation of the horny layer of skin while not affecting qualitative or quantitative changes in structure of the viable epidermis. The mechanism of action has been attributed to dissolution of intercellular cement substance. In a study of the percutaneous absorption of salicylic acid from SALVAX in four patients with extensive active psoriasis, Taylor and Halprin showed that peak serum salicylate levels never exceeded 5 mg/100 ml even though more than 60% of the applied salicylic acid was absorbed. Systemic toxic reactions are usually associated with much higher serum levels (30 to 40 mg/100 ml). Peak serum levels occurred within 5 hours of the topical application under occlusion. The sites were occluded for 10 hours over the entire body surface below the neck. Since salicylates are distributed in the extracellular space, patients with a contracted extracellular space due to dehydration or diuretics have higher salicylate levels than those with a normal extracellular space. (See PRECAUTIONS ). The major metabolites identified in the urine after topical administration are salicyluric acid (52%), salicylate glucuronides (42%), and free salicylic acid (6%). The urinary metabolites after percutaneous absorption differ from those after oral salicylate administration; those derived from percutaneous absorption contain more glucuronides and less salicyluric and salicylic acid. Almost 95% of a single dose of salicylate is excreted within 24 hours of its entrance into the extracellular space. Fifty to eighty percent of salicylate is protein bound to albumin. Salicylates compete with the binding of several drugs and can modify the action of these drugs. By similar competitive mechanisms other drugs can influence the serum levels of salicylate. (See PRECAUTIONS ). The mechanism of action of topically applied salicylic acid has been attributed to the dissolution of intercellular cement substance.
