In arterial insufficiency management, when is cilostazol considered?

• A. Before starting exercise
• B. After starting an exercise regimen
• C. Instead of exercise
• D. Only after revascularization

Answer: (B)

Cilostazol is used as an add-on to exercise therapy to improve walking distance in intermittent claudication due to peripheral arterial disease. It complements, not replaces, structured exercise—so it’s considered after a patient has begun a supervised exercise regimen and symptoms persist. It isn’t started before exercise, nor used instead of exercise, and it isn’t something reserved only after revascularization. By increasing cAMP in vascular smooth muscle and platelets, cilostazol provides vasodilation and antiplatelet effects that help improve perfusion during activity, making it a useful adjunct when exercise alone doesn’t fully relieve symptoms.
