Background: Rho kinase inhibitor. Active metabolite of fasudil (HA-1077). Exists in two tautomers. Hydroxyfasudil relaxes the rabbit basilar artery mainly by disinhibiting myosin light chain phosphatase through the inhibition of rho-associated kinase. The hydroxyfasudil-sensitive Rho-kinase-mediated pathway appears to mediate enhanced myosin light chain  phosphorylations and plays a central role in the pathogenesis of coronary artery spasm.
