What Is Cardizem 240 mg?

Cardizem contains diltiazem hydrochloride, a medication belonging to the non-dihydropyridine calcium channel blocker class. It helps relax blood vessels, improve circulation, reduce heart rate in certain situations, and decrease oxygen demand by the heart.

Extended-release Cardizem 240 mg formulations are designed to provide medication gradually over a 24-hour period, allowing convenient once-daily dosing for many patients.

Medical Uses

Healthcare providers may prescribe Cardizem 240 mg for conditions such as:

• Rate control in selected patients with atrial fibrillation or atrial flutter
• Long-term cardiovascular management under physician supervision

The exact indication depends on the patient’s diagnosis and medical history.

How Cardizem Works

Diltiazem blocks calcium entry into heart muscle and blood vessel cells. As a result:

These combined effects make the medication valuable for managing several cardiovascular disorders.
