Vasoxuprine is a vasodilator that works by relaxing the smooth muscles in the walls of blood vessels, allowing more blood to flow. It is used to treat circulation problems in the extremities, such as Raynaud's disease and intermittent claudication. It helps relieve symptoms such as pain, numbness, and tingling in the legs and feet. Vasoxuprine is used to improve blood flow to the brain, which may help treat some cases of chronic cerebral ischemia. It is used in some cases to improve blood circulation in the inner ear, which may help treat some types of tinnitus and dizziness.
