Microspheres with improved drug encapsulation rate and sustained release ability and method for preparing the same

摘要

The present invention relates to microspheres having improved drug encapsulation rate and sustained release ability and a method for producing the same, and more particularly, to microspheres comprising memantine pamoate salt and made of a biocompatible polymer and a method for producing the same. it's about The microspheres containing memantine pamoate salt according to the present invention exhibit a stable drug release rate for a long period of time, so that memantine can be maintained at an effective concentration in the blood for a certain period of time, thereby extending the drug administration cycle and increasing the patient's medication compliance. , it can alleviate the side effects caused by the rapid initial release of the drug.
