What It Treats
dipyridamole

nicardipine

Nicardipine treats chronic stable angina, which is chest pain that happens when you exert yourself. It can be used alone or with beta-blockers to manage this condition. Nicardipine also treats high blood pressure, and it can be used alone or with other blood pressure medications.

How It Works
dipyridamole

Dipyridamole is an antiplatelet medicine. It helps to keep blood cells called platelets from sticking together and forming clots. This helps your blood flow more freely.

nicardipine

Nicardipine works by blocking calcium from entering certain cells in your heart and blood vessels. This helps to relax and widen your blood vessels, which lowers blood pressure. It also reduces the workload on your heart, which can help to relieve chest pain.
