A method is provided for preparing a stable liposome precursors in the form of a particulate carrier materials coated with thin films of liposome components, which method includes the steps of dissolving at least one liposome-forming amphipathic lipid, optionally, at least one biologically active compound, and, optionally, at least one adjuvant in a suitable solvent and employing the resulting solution to coat a suitable particulate carrier material which is substantially insoluble in the above-mentioned solvent, to form thin films of liposome components thereon. Upon exposing the coated carrier material to water, the thin films of liposome components hydrate. If the carrier material is water-insoluble, it is then separated e.g. by filtration or centrifuging.
本发明提供了一种制备稳定的脂质体前体的方法,其形式为涂有脂质体成分薄膜的微粒载体材料,该方法包括以下步骤:将至少一种脂质体形成两性脂质、可选的至少一种生物活性化合物和可选的至少一种佐剂溶解在一种合适的溶剂中,并用所得溶液涂覆在基本上不溶于上述溶剂的合适的微粒载体材料上,以在其上形成脂质体成分薄膜。将涂覆的载体材料置于水中,脂质体成分薄膜就会水合。如果载体材料不溶于水,则通过过滤或离心等方法将其分离。
