The application research progress of pickering emulsion in pharmaceutical field

Pickering emulsions stabilized by solid microparticles, having the advantages of strong interfacial stability, non-toxicity and eco-friendliness compared with the traditional surfactant-stabilized emulsions, have been the focus of considerable researches in recent years. In this review, the application studies on Pickering emulsions were summarized from the following aspects:the stabilization theory about Pickering emulsions, solid microparticles used in Pickering emulsions, the applications of Pickering emulsions in pharmaceutical field and the new Pickering emulsion stabilized by drug nanocrystalline itself. These research progress would promote and expand the application of Pickering emulsions in pharmaceutical field.
