  • Multilamellar liposomes having improved trapping efficiencies
    Patent number: 4975282
    Abstract: A multilamellar vesicle dispersed in an aqueous phase comprising an aqueous medium, a lipid concentration of at least about 50 mg/ml and a trapping efficiency of at least about 40 percent. The vesicle can be prepared by dispersing the lipid in an aqueous phase to form a multilamellar vesicle, rapidly freezing the multilamellar vesicle to obtain a frozen lipid-aqueous medium mixture, and warming the mixture to obtain a frozen and thawed multilamellar vesicle dispersed in an aqueous phase.
