    摘要: A method for preparing a vesicle dispersion wherein a water-soluble substance is encupsulated in the vesicle, which comprises successively performing: a step of dispersing at least one lipid in an aqueous medium to pre-construct a vesicle dispersion, a step of drying the pre-constructed vesicles to obtain dried vesicles, a step of re-dispersing the dried vesicles in an aqueous solution of the water-soluble substance, and a step of passing the resultant vesicle dispersion through a filter. The method enables the efficient and simple preparation of safe vesicles with a useful substance in high concentration encupsulated therein, with a narrow size distribution, in high yield.
