PHARMACEUTICAL COMPOSITIONS FOR ORAL ADMINISTRATION

摘要

A method for oral administration of an active principle includes the steps of incorporating an active principle in multilamellar vesicles having a diameter of between 0.1 and 25 mum, and a lamellar liquid-crystal internal structure formed, from the center to the periphery of the vesicles, of a stack of concentric bilayers based on amphiphilic agents alternating with layers of water, aqueous solution or solution of a polar liquid, and orally administering a composition containing the active principle incorporated within the vesicles.
