Found in translation: The rationale behind the early development of glibenclamide in large hemispheric infarction.

Many reasons have been put forth to explain the inability to translate neuroprotection in animal stroke models to humans. Following our determination that glibenclamide is an anti-edema drug, not a neuroprotective drug, and the revelation that the "gold standard" middle cerebral artery occlusion used for animal studies models large hemispheric infarction, a subpopulation of ischemic stroke that develops clinically relevant edema that contributes significantly to poor outcomes, we designed an innovative approach to studying the drug in patients with large hemispheric infarction. The approach included careful selection of the relevant patient population, which gave us a high degree of confidence to move forward into humans.
