Abstract：
 The present invention discloses a method for preparing oral slow/control-released medicine particles, and is aimed at providing a method for preparing oral slow-released or constant-speed released medicine particles which is simple in preparation process, is easy to control, high in productivity and high in encapsulation rate. Said preparation method is characterized by that the medicine can be dissolved or suspended in the microencapsulation material solution capable of producing slow-releasing/control-releasing action, then spray-dried so as to obtain the invented medicine particles. Said invention can make human body obtain stable effective therapeutic blood concentration so as to make therapeutic effect-dosage implement optimization.
