Process for producing phospholipid-containing drugs

摘要

The present invention provides a pharmaceutical preparation which is safe, little irritate subjects and comprises a water-insoluble or hardly water-soluble drug at a high level, and a simple and convenient process for producing the preparation. A process for producing a pharmaceutical composition comprising a water-insoluble or hardly water-soluble drug coated with phospholipid, said process comprising mixing a solution containing the water-insoluble or hardly water-soluble drug and phospholipid in an organic solvent with an aqueous solvent, emulsifying the resultant mixture and removing the organic solvent from the emulsion thus obtained to form a phospholipid coating film on the surface of the water-insoluble or hardly water-soluble drug.
