Cardizem
Pronounced: CAR-di-zem
Generic name: Diltiazem hydrochloride
Other brand names: Cardizem CD, Cardizem SR, Cartia XT, Dilacor XR, Tiazac
Diltiazem comes in many different forms of extended release formulations. Your doctor will choose the best one for you. As all of the different formulations of diltiazem are not equivalent, it is important that you do not change brands unless under the advisement of your doctor.
Cardizem and Cardizem CD (a controlled release form of diltiazem) are used in the treatment of angina pectoris (chest pain usually caused by lack of oxygen to the heart due to clogged arteries) and chronic stable angina (caused by exertion). Cardizem CD is also used to treat high blood pressure. Another controlled release form, Cardizem SR, is used only in the treatment of high blood pressure. Cardizem, a calcium channel blocker, dilates blood vessels and slows the heart to reduce blood pressure and the pain of angina.
Doctors sometimes prescribe Cardizem for loss of circulation in the fingers and toes (Raynaud's phenomenon), for involuntary movements (tardive dyskinesia), and to prevent heart attack.
Tiazac and Dilacor XR are used in the treatment of high blood pressure and chronic stable angina. They may be taken alone or combined with other blood pressure medications.
