Method for preparing polymeric microspheres and polymeric microspheres produced thereby

摘要: The present invention relates to a method for preparing polymeric microspheres and produced thereby. More particularly, the microsphere comprising steps of: mixing water-insoluble organic solvent with dispersion solvent; polymer compound, drug so as prepare dispersed phase; phase mixed an emulsion; adding base or acid prepared emulsion remove from thereby, composition delivery microspheres. provides new preparation by removing water-insoluable solvents emulsions using acids, prepration method, Therefore, of is different original evaporation extraction procedures, realizes minimization waste water generation less water, simply prepares target durg-containing within short period.
