개요Fasudil hydrochloride, a novel calcium antagonistic vasodilator, was marketed for the treatment of cerebral vasospasm following subarachnoid hemorrhage (SAH). Fasudil is also a potent inhibitor of myosin light chain kinase and protein kinase C. In contrast to other calcium channel blockers, which regulate the influx of calcium ions through the cell membrane but not involved in the intracellular regulatory mechanism of the calcium, fasudil was suggested to have an intracellular mode of action in relaxing vascular smooth muscle. In patients with neurological deficits due to vasospasm, fasudil decreased the occurrence of angiographic severe and symptomatic vasospasm and cerebral infarction without decreasing systemic blood pressure. Fasudil is reportedly in clinical trials for acute ischemic stroke, sequelae of cerebral vascular diseases and angina pectoris.
