PROBLEM TO BE SOLVED: To provide a method of making liposomes for use as nutraceuticals or pharmaceuticals.SOLUTION: A method comprises: solubilizing at least about 18 w/w% of vesicle-forming lipids in about 1-12 w/w% of an aqueous solvent or water-miscible solvent at room temperature to form a lipid solution; solubilizing the agent in 0.005-0.01 w/w% of EDTA at room temperature to form an agent-containing solution; filtering the agent-containing solution; injecting the lipid solution into the agent-containing solution while mixing; and allowing the resulting lipid and agent-containing solution to hydrate for at least one hour with frequent mixing, thereby making liposomes.【課題】栄養補助剤又は医薬品として使用されるリポソームの製造方法を提供する。【解決手段】少なくとも約18w/w%のベシクル形成脂質を約1~12w/w%の水性溶媒又は水混和性溶媒に室温で可溶化して脂質溶液を形成し、前記薬剤を0.005~0.01w/w%のEDTAに室温で可溶化して薬剤含有溶液を形成し、前記薬剤含有溶液をろ過し、前記脂質溶液を前記薬剤含有溶液に攪拌しながら注入し、得られる脂質及び薬剤含有溶液を頻回攪拌しながら少なくとも1時間水和させ、リポソームを製造する。【選択図】なし
