  • High-concentration liposome processing method
    Patent number: 4781871
    Abstract: A method of preparing a concentrated liposome suspension having a lipid concentration of greater than about 250 .mu.m/ml and liposome sizes no greater than about 0.4 microns. A solution of vesicle-forming lipids in a chlorofluorocarbon solvent is injected under selected conditions into an aqueous medium, with continual solvent removal. During the lipid injection and solvent-removal steps, the liposomes formed in the aqueous medium are extruded through a membrane, to reduce liposome sizes to less than about 0.6 microns. The lipid injection, solvent removal, and extrusion steps are continued until a lipid concentration of at least about 150 .mu.m/ml is reached.
    Type: Grant

    Date of Patent: November 1, 1988
    Assignee: Liposome Technology, Inc.

  • High-encapsulation liposome processing method
    Patent number: 4752425
    Abstract: A method of preparing a suspension of liposomes containing a water-soluble compound predominantly in liposome-encapsulated form. A solution of vesicle-forming lipids in a chlorofluorocarbon solvent is infused under selected conditions into an aqueous medium, with continual solvent removal. The lipid infusion and solvent removal steps are continued until a lipid concentration of at least about 150 .mu.m/ml is reached, at which point more than about half of the compound contained in the resultant liposome suspension is in encapsulated form.
