[Future neuroprotective strategies in the post-thrombolysis era--neurovascular unit protection and vascular endothelial protection].

From an appearance of recombinant tissue plasminogen activator (rt-PA) in the clinical therapy on 2005 in Japan, the therapeutic strategy of ischemic stroke therapy is now changing dramatically. Many experimental data from animal stroke and clinical trials of neuroprotective agents failed to clinical useful therapeutic strategy. A free radical scavenger, edaravone is the first clinical drug for neuroprotection in the world which has been used in almost all ischemic stroke patients in Japan from 2001. Now, it is especially useful in thrombolytic therapy with rtPA, whereas we still need the newly more effective neuroprotective drugs which can be applied to many ischemic stroke patients. Therefore, we review and describe the future neuroprotective strategies in the post-thrombolysis era.
