Salbetan is a combination drug for application to the skin. It contains betamethasone dipropionate (a corticosteroid) and salicylic acid (a substance with exfoliating effects). Betamethasone dipropionate reduces inflammation and allergic reactions in the skin, as well as reactions associated with excessive division of skin cells. Salicylic acid relaxes the outer (horny) layer of the skin and facilitates the absorption of the corticosteroid.
Salbetan is used to treat psoriasis (psoriasis vulgaris).
