    Abstract: Sustained release microparticles containing risperidone and a preparation method thereof are provided to avoid initial burst of risperidone, and maintain a constant release rate and effective risperidone concentration in blood for a long period of time. The method for preparing the sustained release microparticles containing risperidone comprises the steps of: (i) dissolving a biodegradable polymer in organic solvent to prepare biodegradable polymer solution having viscosity of 1.0 to 10 mPa s; (ii) adding risperidone and a release-regulating agent into the biodegradable polymer solution and mixing them to prepare an organic phase; and (iii) dispersing the organic phase in water to form oil in water(O/W) emulsion, and freeze-drying the O/W emulsion, wherein the biodegradable polymer is polylactide, polyglycolide, poly(lactide-co-glycolide)(PLGA), poly-beta-hydroxybutyl acid, polycarprolactone, polyanhydride, polyorthoester, polyurethane, poly(butyl acid), poly(valeic acid) or poly(lactide-co-carprolactone); the release-regulating agent is poloxamer, sesame oil, hydroxypropyl beta cyclodextrin, glycerin or mannitol. The amount of the release-regulating agent is 2.5-10 wt.% based on the total weight of the microparticles.
