Liposomes with enhanced circulation time
摘要：
A liposome composition which contains between 1-20 mole percent of an amphipathic lipid derivatized with a polyalkylether, as exemplified by phosphatidylethanolamine derivatized with polyethyleneglycol. The derivatized lipid enchances the circulation time of the liposomes severalfold, and this enhancement is achieved with either fluid or membrane-rigidifying liposome components. Also disclosed are methods for delivering a drug for slow release from the bloodstream, and for targeting a selected tissue or cells with liposomes, via the bloodstream.
