    摘要: The present invention relates to a liposome having a phospholipid bilayer and a hydrophilic core, wherein the phospholipid bilayer contains D-alpha tocopheryl polyethylene glycol 1000 succinate (TPGS). The liposomes are first prepared by solvent injection and extrusion method, and then drug loading by ammonium sulfate gradient. The TPGS in the liposome composition can prolong the circulation time of liposomes and thus increase the chance for the drug composition to enter target sites so as to improve the efficiency of drug delivery.
