NOT FOR OPHTHALMIC, ORAL OR INTRAVAGINAL USE. DESCRIPTION:KERALYT is a gel for topical administration containing salicylic acid 6%, in a vehicle composed of propylene glycol, SD-40 alcohol (21%), hydroxypropylcellulose and purified water. Salicylic acid is the 2 hydroxy derivative of benzoic acid having the following structure: CLINICAL PHARMACOLOGY: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. ¹ ²The mechanism of action has been attributed to a dissolution of intercellular cement substance. ³In a study of the percutaneous absorption of salicylic acid from KERALYT GEL in four patients with extensive active psoriasis, Taylor and Halprin ⁴showed 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. ⁵(See PRECAUTIONS). The major metabolites identified in the urine after topical administration are salicyluric acid (52%), salicylate glucuronides (42%), and free salicylic acid (6%). ⁴The urinary metabolites after percutaneous absorption differ from those after oral salicylate administratio Read the complete document
