The present invention concerns a method for preparing liposomes, said method comprising the following steps: (I) mixing at least one liposome-forming lipid, a water-miscible organic solvent and aqueous medium Y to form a gel or liquid containing gel particles without sonication; and thereafter (II) (a) mixing the gel or liquid containing gel particles with aqueous medium Z1 to directly form the liposomes; (b) (i) mixing the gel or liquid containing gel particles with aqueous medium Z1 to form a curd or curdy substance; and (ii) mixing the curd or curdy substance with aqueous medium Z2 to directly form the liposomes; or (c) (i) cooling the gel or liquid containing gel particles to form a waxy substance; and (ii) mixing the waxy substance with aqueous medium Z1 to directly form the liposomes; wherein aqueous media Y, Z1 and Z2 are the same or different.
本发明涉及一种制备脂质体的方法,该方法包括以下步骤:(I)混合至少一种脂质体形成的脂质、一种水溶性有机溶剂和水介质Y,以形成不经超声处理的含有凝胶颗粒的凝胶或液体;然后(II)(a)将含有凝胶颗粒的凝胶或液体与水介质Z1混合,直接形成脂质体;(b)(i)将含有凝胶颗粒的凝胶或液体与水介质Z1混合,形成凝乳或凝块物质;(ii)将凝乳或凝块物质与水介质Z2混合,直接形成脂质体;或(c)(i)将含有凝胶颗粒的凝胶或液体冷却成蜡状物质;(ii)将蜡状物质与水介质Z1混合,直接形成脂质体;其中水介质Y、Z1和Z2相同或不同。
