| titleOfInvention | Preparation method of microspheres for injectables |
| abstract | The present invention relates to a method of manufacturing microspheres for injection, a specific method of manufacturing is a) by dissolving by adding a biodegradable polymer to an organic solvent, and dissolving or dispersing by adding a drug to a solution in which the biodegradable polymer is dissolved. Forming a solution; b) dissolving the emulsifier in water to form a second solution; c) mixing the first solution and the second solution to form a biodegradable polymer droplet containing a drug; d) forming a biodegradable polymer microsphere comprising a drug; And e) filtering, washing and drying the microspheres to remove the emulsifier. In detail, the emulsifier is characterized in that the polyvinylpyrrolidone-polyvinyl acetate copolymer (poly(vinyl pyrrolidone-co-vinyl acetate), PVP/VAc) represented by the following formula (I). Formula I In the formula (I), n is the mole number of polyvinylpyrrolidone, and m is the mole number of polyvinyl acetate. |
