Diltiazem is a calcium channel blocker.
Diltiazem is used for the treatment of:
• High blood pressure
• Chronic stable angina (chest pain)
Diltiazem may be used alone or in combination with other medicines.
Diltiazem works by relaxing and opening up the blood vessels. This allows blood to circulate more freely around the body, lowering blood pressure and allowing the heart to work more efficiently.
Calcium channel blockers do not change the amount of calcium in your blood or bones.
