Clazosentan, Endothelin-A Receptor Antagonist, Suppresses Interleukin-6 Expression in Cerebrospinal Fluid after Subarachnoid Hemorrhage
Clazosentan (CLA), an endothelin-A receptor antagonist, is used to prevent cerebral vasospasm (CV) following subarachnoid hemorrhage (SAH). Although its efficacy has been demonstrated in large-scale clinical trials, the effects of CLA on...
