Abstract
The process consists in dissolving a corticosteroid in the lipid phase of nonionic amphiphilic lipid vesicles consisting of one or more lipid lamellae. Composition for carrying out the above process, in which the vesicles are dispersed in an aqueous phase D, have an average diameter of between 10 and 5,000 nm and contain as corticosteroids 17- and/or 21-mono- or -diesters of hydrocortisone, cortisone, prednisone, prednisolone or 6-methylprednisolone, the corticosteroids representing 0.5 to 2.5% by weight of the total lipids of the lamellae.
