Abstract
A pharmaceutical preparation for topical treatment of skin disorders, particularly psoriasis, comprising active ingredients consisting essentially of combinations of 1,8,9-anthracenetriol, and/or derivatives thereof, and urea. The subject preparation is applied in an essentially water-free excipient. The preparation includes surfactants, which are ordinarily incompatible with the active ingredients. By the use of surfactant-urea combinations, surfactants can be incorporated into a stable, lipophilic pharmaceutical preparation, whereby after use the surfactants are liberated by the action of water, to form a readily washable emulsion system. The inventive preparation is advantageously used in the 'short time' method of therapy of psoriasis.
