What is Pletal (cilostazol)?
Cilostazol is a vasodilator that works by relaxing the muscles in your blood vessels to help them dilate (widen). Cilostazol dilates arteries that supply blood to your legs. Cilostazol also improves circulation by keeping platelets in the blood from sticking together and clotting.
Cilostazol is used to treat the symptoms of intermittent claudication. This condition causes reduced blood flow to the legs, leading to pain while walking. Cilostazol improves your ability to walk longer distances without pain.
