Abstract
A method for producing microparticles containing a poorly soluble drug, and microparticles produced by the method are proposed. According to the method for preparing microparticles, it is possible to produce microparticles that are uniform and of good quality and have high encapsulation efficiency for the poorly soluble drug and low contents of residual organic solvents, by using at least two organic solvents.
Claims18
A method for producing microparticles containing a poorly soluble drug, the method comprising steps of:
- 1) preparing an oil phase solution by dissolving a poorly soluble drug and a biodegradable polymer in a mixed solvent comprising at least two organic solvents;
- 2) preparing a water phase solution by dissolving a surfactant in water;
- and
- 3) producing microparticles using the oil phase solution and the water phase solution.
