Cardizem is a prescription drug approved by the U.S. Food and Drug Administration (FDA) to treat hypertension, chronic stable angina, and angina due to coronary artery spasm. Cardizem is sometimes prescribed to treat cases of pulmonary hypertension, especially idiopathic pulmonary hypertension. Cardizem may be referred to by its drug name, diltiazem.

Cardizem is a calcium channel blocker. Calcium channel blockers are believed to work by dilating the arteries and decreasing the force with which the heart pumps.

How do I take it?
Cardizem is generally taken three or four times a day.

Cardizem comes in tablet form.
