METHOD FOR PREPARING VESICLES LOADED WITH BIOLOGICAL MATERIAL, THEIR USES AND A COMBINATION OF PHARMACEUTICAL COMPOSITIONS FOR PREPARING SUCH VESICLES

摘要

The present invention discloses a method for an efficient entrapment of active biological material in liposomes. The method is based on the steps of drying a suspension of liposome-forming lipids and then hydrating the dry composition obtained with an aqueous solution containing a biologically active material to be entrapped in high yield in the liposomes thus formed. The invention also concerns liposomal formulations produced by the method of the invention and their uses.
