What physiological effect does cilostazol have in treating claudication?

• A. Increases blood viscosity
• B. Inhibits platelet aggregation and provides direct arterial vasodilation
• C. Reduces inflammation in the blood vessels
• D. Increases cholesterol excretion

Answer: (B)

Cilostazol is primarily used to treat intermittent claudication, a condition characterized by muscle pain due to inadequate blood flow during physical activity. The drug works by two main mechanisms: it inhibits platelet aggregation and promotes vasodilation of the arteries. Inhibiting platelet aggregation is significant because it reduces the chance of clot formation in the small blood vessels that supply the muscles, thereby enhancing blood flow. This is particularly important in patients with claudication, as the goal is to optimize the oxygen delivery to the affected muscle tissues during exertion. Additionally, cilostazol provides direct arterial vasodilation, which means it relaxes and widens blood vessels, further improving blood flow. This dual action helps alleviate symptoms of claudication by ensuring that more blood reaches the ischemic areas during physical activity. Restoring and improving blood flow is crucial in managing claudication symptoms, making cilostazol an effective treatment option.
