A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Chemical Name: Diltiazem (dil-TYE-a-zem)
Cardizem SR is 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). Diltiazem is also used to treat high blood pressure. Another controlled release form, Diltiazem SR, is used only in the treatment of high blood pressure. Diltiazem, a calcium channel blocker, dilates blood vessels and slows the heart to reduce blood pressure and the pain of angina. Doctors sometimes prescribe Diltiazem for loss of circulation in the fingers and toes (Raynaud's phenomenon), for involuntary movements (tardive dyskinesia), and to prevent heart attack.
SIDE EFFECTS, that may go away during treatment, include headache, facial flushing, or constipation. If they continue or are bothersome, check with your doctor. CHECK WITH YOUR DOCTOR AS SOON AS POSSIBLE if you experience tender, bleeding, or swollen gums; irregular heartbeat; dizziness; or swelling of the feet or hands. If you notice other effects not listed above, contact your doctor, nurse, or pharmacist.
