How Nifedipine Works

Nifedipine works by blocking calcium from entering the cells of the heart and blood vessels. This action relaxes the blood vessels, allowing blood to flow more easily.

By reducing the workload on the heart, it helps to lower blood pressure and decrease the frequency of chest pain.
