Abstract:
(EN) A liposome suspension forms spontaneously upon adding a lipid composition to an aqueous solution. The lipid composition comprises a single lipid or a mixture of lipids that have appropriate packing parameters, that includes polyethyleneglycol, and that has a melting temperature which allows it to be in liquid form when mixed with the aqueous solution. Such liposome suspensions are useful for a variety of purposes, including the delivery of therapeutic agents.
(FR) L'invention concerne une suspension de liposomes se formant spontanément à l'ajout d'une composition lipidique à une solution aqueuse. Cette composition lipidique comporte un lipide simple ou un mélange de lipides qui présente des paramètres de remplissage appropriés, qui contient du polyéthylèneglycol et qui a une température de fusion qui lui permet d'être sous forme liquide lorsqu'il est mélangé à la solution aqueuse. De telles suspensions de liposomes sont utiles à des fins différentes, notamment à l'obtention d'agents thérapeutiques.
