摘要：

A manufacturing method of powder including nano particles of insoluble drug is provided to maintain stability in case that insoluble drug is re-dispersed at aqueous solution, to be no side effect by impurity and to improve bio-availability. A manufacturing method of powder including nano particles of insoluble drug comprises steps of: adding particles of insoluble drug which is active component, a surface passivating agent and additional dispersion secondary particle in aqueous solution including dispersion secondary particle to aturation concentration; mixing, shattering and homogenizing the obtained dispersed solution; and centrifuging or filtering the homogenized dispersed solution and drying it and obtaining the powder from the dispersed solution.
