Abstract:
Provided is a method for preparing a liposomal composition. The method comprises the step of contacting a liposome solution with a mild acidic agent for a limited time. The liposome solution comprises a weak acid salt encapsulated within an aqueous interior space separated from the aqueous medium by a membrane comprised of a lipid mixture containing one or more lipids and a hydrophilic polymer conjugated lipid at a molar percentage of less than 3% based on the total amount of the lipid mixture. The time for encapsulating the agent to a desired amount at a predetermined ratio to lipids is dramatically reduced even under a condition without elevating the temperature to above ambient environment.

Claim (Index 52):
A liposomal composition, comprising\n a delivery vehicle, said delivery vehicle comprising a liposome in an aqueous medium, wherein the liposome comprises a combination of a weak acid salt and an organic tribasic acid encapsulated within the liposome, wherein the weak acid salt is sodium acetate, potassium acetate or calcium acetate; and an arachidonic acid metabolite.
