This invention relates to biotechnology, more particularly, to an improved liposomal drug delivery system. Liposomes treated with or incorporating a surface active dopant, such as those containing polymers or oligomers of ethylene glycol as their hydrophilic “headgroup” component, have strongly increased permeabilizability when exposed to ultrasound. Permeabilizability was measured by the rate of release of self-quenching fluorescent dye at concentrations that caused no increase in permeability in the absence of ultrasound. The surface active dopants reached maximal effectiveness at about 1% of their critical micelle concentration. As disclosed by the present invention, surface active dopants, such as a PEG-lipid and a PLURONIC® triblock copolymer and a PEG-PBLA block copolymer, can be irreversibly incorporated into liposomes to give formulations for use as drug delivery vehicles.
