ABSTRACT:
Stable solutions of lipophilic drugs, such as cyclosporin, forming a polar lipid self-emulsifying drug delivery system. The solutions can include lipophilic drugs, such as cyclosporin, dissolved in a polar lipid, such as having a C6-C12fatty acid monoglyceride content of at least about 50%, surfactants and triglycerides. The composition forms a fine emulsion on exposure to water. The encapsulated dosage form of this composition needs neither a hydrophilic component nor air-tight blister packaging, and is particularly suitable for oral administration.
