Dopropidil is primarily used as a vasodilator, making it effective in treating conditions related to poor blood circulation. It is often prescribed to alleviate symptoms of peripheral vascular diseases, such as intermittent claudication, by improving blood flow to the extremities. Additionally, it has been utilized in managing certain cardiovascular disorders, helping to reduce hypertension and enhance overall vascular health. Its ability to relax blood vessels also makes it beneficial in treating Raynaud's phenomenon, a condition characterized by reduced blood flow to the fingers and toes. In some cases, it is employed to support recovery in patients with ischemic stroke by promoting cerebral circulation.
