Cilostazol
A phosphodiesterase 3 inhibitor that inhibits platelet aggregation and acts as a vasodilator, used to reduce symptoms of intermittent claudication in peripheral artery disease, improving walking distance. It is contraindicated in patients with heart failure of any severity because PDE3 inhibitors have been associated with increased mortality in this population. Headache and palpitations are common side effects reflecting its vasodilatory and cardiac effects.
