Cardizem is a calcium-channel blocker. Cardizem is prescribed to treat chest pain caused by angina. Cardizem affects the amount of calcium found in your heart and muscle cells. This relaxes your blood vessels, which can reduce the amount of work the heart has to do.
Cardizem works by relaxing the blood vessels so the heart does not have to pump as hard.
Cardizem is prescribed to treat high blood pressure and to control chest pain (angina).
Cardizem is in a class of drugs called calcium-channel blockers.
