Cilodoc 50 Tablet contains vasodilator (blood vessel widening) medication, Cilostazole, which is primarily used to treat pain in the legs due to insufficient blood flow (intermittent claudication). It also reduces cramping, numbness or weakness in the legs on walking in such patients. Intermittent claudication is a peripheral vascular disease in which you have cramp-like pain in your legs when you walk and is caused by an insufficient blood supply in your legs.
