[Emphasizing the research for ocular drug delivery system].

Choosing appropriate drug delivery system can apparently improve drug efficacy, prolong action time and decrease adverse reaction. In recent years, with the progress of macromolecule chemistry, the research of ocular drug delivery system has been developed rapidly. The present article reviews the progress of ocular drug delivery system and its development in our country. This article also discusses how to exploit the macromolecule polymer material with independence intellectual property rights, and how to promote the studies of intraocular pharmacokinetics and ocular toxicology about new ocular drug delivery system.
