摘要
The present invention relates to a method for preparing a sustained-release microsphere which can control the long-term release of a drug. More particularly, as the preparation of a microsphere in which a drug is loaded in a carrier comprising a biodegradable polymer, the present invention relates to a method for preparing a sustained-release microsphere wherein a solvent intra-exchange evaporation method by means of co-solvent is used for suppressing the initial burst release of physiologically active substance, to release the physiologically active substance in the body continuously and uniformly.
