Abstract:
In the present invention, the whole preparation process of the sustained-release microparticles is at normal or low temperature, which is highly advantageous for the preparation of a polymer-based composition from a high-temperature-sensitive drug, particularly a protein, nucleic acid and peptide drug, and the bioactivity of the active substance can be maintained to the greatest extent throughout the process compared to the disclosed technology; at the same time, the prepared sustained-release microparticles have an excellent sustained-release effect close to zero order, and the drug concentration is stabilized during the release, which overcomes the defects that the microparticles obtained by the conventional S/O/W process of pre-preparing the drug microparticles have no drug release in the earlier stage and a rapid release of the drug in the later stage; and in addition, the sustained-release microparticles have higher drug loading rate and drug encapsulation rate.

Claim (Index 10):
Sustained-release microparticles obtained by the preparation method of sustained-release microparticles according to  claim 1 .
