IMPROVED PREPARATION METHOD FOR BIODEGRADABLE POLYMERIC MICROSPHERES USING SOLVENT EXTRACTION AND PREPARATION METHOD FOR MICROSPHERES FOR TREATING LOCAL INFLAMMATION USING THE SAME

摘要

Provided are an improved method for preparing biodegradable polymer microspheres using a solvent extraction method and a method for producing microspheres for treating local inflammatory diseases using the same. In the method of the present invention, the solidification of the polymer can be achieved in a short time by adding the insoluble solvent of the polymer to the external water in advance, and as a result, the encapsulation rate of the drug can be improved.
