Mode of Action

Coal tar has antipruritic, keratoplastic and keratolytic properties. It slows down excessive epidermal cell turnover and is often used topically either alone or in combination with other drugs (e.g. salicyclic acid, sulfur) in conditions such as dandruff, seborrheic dermatitis or psoriasis. Sulfur is a keratolytic, mild antiseptic, mild antifungal and parasiticide. Salicylic acid has a potent keratolytic action and a slight antiseptic action when applied topically. It softens and destroys the stratum corneum by increasing endogenous hydration which causes the horny layer of the skin to swell, soften, and then desquamate. At high concentrations, salicylic acid has a caustic effect. It also possesses weak antifungal and antibacterial activity.

Precaution

Use with caution on the face, near eyes and mucous membranes. Do not apply to genital or rectal areas. Avoid use in patient with exacerbation of psoriasis. Avoid exposure to direct sunlight and sunlamps for at least 24-72 hr after application. May stain clothes and hair.
