Used primarily to improve blood flow in patients with peripheral vascular diseases, this compound helps alleviate symptoms of poor circulation such as leg pain, cramping, and numbness, especially in conditions like intermittent claudication. It acts by reducing vascular resistance and enhancing oxygen delivery to tissues. Also investigated for potential neuroprotective effects in ischemic conditions due to its ability to modulate cerebral blood flow and reduce neuronal damage. Occasionally used off-label to support cognitive function in vascular dementia, though evidence remains limited.
