A mixed
liposome pharmaceutical formulation with multilamellar vesicles, comprises a proteinic pharmaceutical agent, water, an
alkali metal lauryl sulphate in a concentration of from 1 to 10 wt. / wt. %, at least one membrane-mimetic
amphiphile and at least one
phospholipid. The membrane-mimetic
amphiphile is
hyaluronic acid, pharmaceutically acceptable salts of
hyaluronic acid, lauramidopropyl betain, lauramide monoisopropanolamide,
sodium cocoamphopropionate, bishydroxypropyl dihydroxypropyl stearammonium
chloride, polyoxyethylene dihydroxypropyl stearammonium
chloride, dioctadecyldimethylammonium
chloride, sulphosuccinates, stearamide DEA, gamma-
linoleic acid,
borage oil,
evening of primrose oil, monoolein,
sodium tauro dihydro fusidate,
fusidic acid,
alkali metal isostearyl lactylates,
alkaline earth metal isostearyl lactylates, panthenyl triacetate, cocamidopropyl phosphatidyl PG-diammonium chloride, stearamidopropyl phosphatidyl PG-diammonium chloride,
borage amidopropyl phosphatidyl PG-diammonium chloride,
borage amidopropyl
phosphatidylcholine, polysiloxy pyrrolidone linoleyl
phospholipid, trihydroxy-oxo-cholanylglycine and
alkali metal salts thereof, and octylphenoxypolythoxyethanol, polydecanol X-lauryl
ether, polydecanol X-
oleyl ether, wherein X is from 9 to 20, or combinations thereof. The
phospholipid is phospolipid GLA,
phosphatidyl serine,
phosphatidylethanolamine, inositolphosphatides, dioleoylphosphatidylethanolamine,
sphingomyelin, ceramides, cephalin,
triolein,
lecithin, saturated
lecithin and lysolecithin, or a combination thereof. The amount of each membrane mimetic
amphiphile and phospholipid is present 1 to 10 wt. / wt. % of the total formulation, and the total concentration of membrane mimetic amphiphiles and phospholipids is less than 50 wt. / wt. % of the formulation.
