摘要： A microparticle dispersion liquid manufacturing apparatus 10 includes a controller 11, a light source 12, an irradiation optical system 13, and a container 14. A solid object 1 is contained in and a solvent 2 is injected into an interior of the container 14 to enable attainment of a state where the solid object 1 is in contact with the solvent 2. The light source 12 repeatedly outputs pulsed light. By repeatedly irradiating the solvent 2 with the pulsed light from the light source 12, expansion and contraction of the solvent 2 is made to occur repeatedly at the irradiated portion, thereby generating a pressure wave in the solvent 2, and the pressure wave is made to act on the solid object 1 to finely pulverize the solid object 1 and thereby manufacture a microparticle dispersion liquid in which microparticles are dispersed in the solvent. A microparticle dispersion liquid manufacturing method and manufacturing apparatus are thereby realized by which both suppression of impurity formation and an increase in efficiency of microparticle formation can be achieved readily.

摘要： In a dissolving step, in a container 13, a poorly soluble drug and a dispersion stabilizer (polyvinylpyrrolidone and sodium lauryl sulfate) are dissolved in a volatile organic solvent. In a solid composition forming step following the dissolving step, the organic solvent contained in the solution is removed by evaporation, and by the organic solvent removal, a solid composition 1 is obtained as a residue, and the solid composition 1 becomes fixed on the inner wall of the container 13.

In a microparticle dispersion liquid preparing step following the water injecting step, laser light L emitted from a laser light source 11 is irradiated on the solid composition 1 fixed on the inner wall of the container 13 and optical energy is thereby applied to the solid composition 1.
