Felodipine extended-release tablets
What do felodipine extended-release tablets do?
FELODIPINE (Plendil(R)) is a calcium-channel blocker. It affects the amount of calcium found in your heart and muscle cells. This results in relaxation of blood vessels, which can reduce the amount of work the heart has to do. Felodipine reduces high blood pressure (hypertension). It is not a cure.
What should my health care professional know before I take felodipine?
