ABSTRACT:
A sustained-release particulate preparation having a controlled releasing rate of a pharmacologically active agent contained therein in the living body, and a process for preparing the preparation are disclosed. The preparation comprises a polymeric compound which is capable of being degraded in the living body and which is compatible with living tissue, a pharmacologically active agent, and a natural high molecular weight compound of sugar origin or a derivative thereof. The preparation has fine and uniform particle size and can be administered subcutaneously or intramuscalarly for obtaining a long-lasting pharmacological activity.
