摘要:
Pharmaceutical composition for topical application to the skin, comprising an oil-in-water emulsion containing dithranol. This composition contains, in order to prevent the oxidation of the dithranol, nonionic vesicles prepared from a lipid phase containing at least one nonionic amphiphilic lipid. These vesicles are dispersed in the aqueous phase of the emulsion.
