METHOD FOR PREPARING STEROCOMPLEX POLYLACTIC ACID COMPLEX USING OIL IN WATER EMULSION MIXING METHOD FOR PREPARING COMPOSITION FOR DRUG DELIVERY USING THE SAME AND COMPOSITION FOR DRUG DELIVERY PREPARED THEREBY

摘要

The present invention relates to a method for preparing a stereocomplex polylactic acid complex using an oil-in-water emulsion mixing method, a method for preparing a composition for drug delivery using the same, and a composition for drug delivery prepared thereby, and more particularly, to an oil-in-water emulsion mixing method Compared to the conventional solution mixing method, melt blending method, or supercritical fluid method by using the In addition, the composition for drug delivery according to the present invention can support the drug in the polymer chain of the stereocomplex polylactic acid very easily and efficiently by the oil-in-water emulsion mixing method, and has the advantage of easy drug release at room temperature for a long period of time.
