In the present review (part II), we discuss the challenges and promises of selective drug delivery to ischemic brain tissue by liposome technologies. In part I of this serial review, we proposed "selective drug delivery to ischemic brain tissue" as a technique for neuroprotective treatment of acute ischemic stroke. To be effective, drugs must pass a series of barriers to arrive at ischemic brain. Brain ischemia results in metabolic and structur-al changes in the ischemic region, which cause additional obstacles for drug delivery. Liposome drug delivery system can pass these barriers and selectively target ischemic tissue by utilizing ischemia-induced changes in metabolism and molecular structure.
