Suloctidil is primarily used in the treatment of peripheral vascular diseases. It works by improving blood flow, reducing blood viscosity, and inhibiting platelet aggregation, which helps in managing conditions like intermittent claudication and other circulatory disorders. Additionally, it has been explored for its potential neuroprotective effects, particularly in cases of cerebral ischemia, where it may help in reducing neuronal damage. Its vasodilatory properties also make it beneficial in alleviating symptoms associated with poor circulation in the extremities.
