Cardizem (Diltiazem)

What is Cardizem?

Cardizem CD (Diltiazem CD) belongs to the class of generic drugs called anti-hypertensive drugs or calcium channel blockers (CCBs) and is generally used in treating symptoms of high blood pressure (hypertension) or chest pain (angina pectoris).


Cardizem Facts

Calcium is associated with the narrowing of the blood vessels as well as in regulating the electrical impulses within the heart. By blocking calcium, this medication relaxes and widens blood vessels and can normalize heartbeats. Cardizem CD (Diltiazem CD) works by slowing the heart rate and by relaxing and widening blood vessels (arteries), which, in turn, reduces the blood pressure. Widening of the arteries also increases the amount of blood reaching the heart. Calcium-channel blockers slow the rate at which calcium passes into the heart muscle and into the vessel walls, which relaxes the vessels and they allow blood flow more easily through them, thereby lowering blood pressure. In addition, this generic drug also augments the supply of blood and oxygen to the heart. Patients using this generic drug for hypertension should remember that this medication does not cure the problem; but merely controls it. Patients taking this medication for angina should not abruptly stop taking it, as it may result in increased risk of heart attacks.
