Cilostazol is used to treat intermittent claudication. This is a cramping pain that develops in the lower leg when you walk and is due to poor circulation. Vasodilators like cilostazol increase the distance you can walk before the pain develops.
Cilostazol works in two ways. It increases blood flow by widening the blood vessels of the affected areas and it also reduces the clotting activity of blood cells called platelets. Cilostazol is prescribed by specialist doctors when it is not possible to improve the symptoms of intermittent claudication by other means.
