POLYMERIC MICROPARTICULATES FOR SUSTAINED RELEASE OF DRUG AND THEIR PREPARATION METHODS

摘要

The present invention relates to polymeric microparticulates for sustained release of drug and to the process for the preparation thereof. The process of the present invention for preparing polymeric microparticulates based on microcoagulation phenomenon of water-soluble polymer not only improves loading amount of drug but also minimizes initial burst of drug, thereby providing polymeric microparticulates enabling sustained and prolonged release of drug
