Abstract: Because of their short half-life, hydrophilic small molecule drugs need frequent administration and sustained release microspheres can control the release of drug and therefore overcome this disadvantage. This article reviewed the present preparation status and development direction of microencapsulating hydrophilic small molecule drugs, and introduced the advantages and disadvantages of different preparation methods from the view of using different support materials. Emulsion solvent evaporation method and phase separation method were elaborated for water-insoluble support materials, while for water-soluble support materials, emulsion crosslinking method and spray drying method were discussed. Then the technical principles and preparation procedures of layer-by-layer self-assembly method and solvent evaporation method with magnetic particles were analyzed. It was pointed out that the development of encapsulating hydrophilic small molecule drugs would favor simple, safe and effective and intelligent target operation.

Key words: pharmaceuticals, preparation, support, sustained release microspheres, hydrophilic small molecule, intelligent target
