Abstract
In a dissolving step, a poorly soluble drug and a dispersion stabilizer are dissolved in a volatile organic solvent. In a fixing step, the organic solvent, contained in a solution obtained in the dissolving step, is removed by evaporation, pellet-form residuesare obtained by the organic solvent removal, and the residuesare fixed on respective bottom surfaces of a plurality of locations of a container. In a water injecting step, wateris injected into each of a plurality of recessesof the container. In an irradiating step, laser light L, emitted from a light irradiating unit, is irradiated simultaneously or successively on the residuesfixed on the respective bottom surfaces of the recessesof the container, and the residuesare thereby pulverized and made into microparticles and a microparticle dispersion liquid, constituted of the microparticles being dispersed in the water, is manufactured.
