Claims8
A pharmaceutical composition for topical application comprising a topically active anti-inflammatory corticosteroid in a multiple emulsion in which the continuous phase is aqueous and the primary disperse phase is an oil phase in which a hydrophilic phase containing the steroid in saturated solution is dispersed.
A process for preparing a pharmaceutical steroid composition for topical application which is a multiple emulsion characterized in dissolving a topically active anti-inflammatory corticosteroid, combining the steroid solution together with an oil-soluble emulsifier with an oil-phase forming material, and thereafter combining this steroid solution in oil emulsion with an aqueous solution prepared by dissolving a water-soluble emulsifier in water or a mixture of water and a fatty alcohol to form a multiple emulsion.
