Cardizem CD is a prescription controlled-release antihypertensive (blood pressure reducing) that treats high blood pressure, also known as hypertension. Cardizem CD relaxes heart and blood vessel muscles, slowing down the heart and dilating blood vessels to reduce blood pressure.
The active ingredient in Cardizem CD, diltiazem, is a calcium channel blocker. These substances work by reducing the electrical signals in muscles like the heart. As a result, the heart beats with less force and the heartbeat slows down. Calcium channel blockers also relax the muscles in blood vessel walls, increasing their width. Both effects combined bring down blood pressure.
Cardizem CD is also prescribed to treat angina (chest pain). Angina results from poor blood flow through arteries that feed blood to the heart. As a calcium channel blocker, Cardizem CD increases the width of the heart's arteries to help prevent angina episodes.
Cardizem CD is taken as a capsule once daily. The dose for either hypertension or angina will depend on the patient's response to the medication.
The most common physical side effects include, but are not limited to, swelling in the feet, ankles, or hands, slow heartbeat, palpitations, flushing, dizziness, sore throat, stuffy nose, and coughing. Mental and mood changes are very rare and include agitation, depression, and unusual dreams. Allergic reactions are rare.
