Pletal (Cilostazol) is one of the recommended drugs used for treating peripheral vascular disease (PVD) and it works in two ways:
1) It inhibits platelet aggregation thereby decreasing the likely hood of clots in your peripheral blood vessels.
2) It directly dilates arteries to improve blood flow.
Pletal has been shown in scientific studies to improve walking distance in people with PVD and can be safely used in combination with aspirin. However, it is contraindicated in patients with congestive heart failure.
