I. Tricor Fact File
Tricor was manufactured by Abbott Laboratories.
Founded in 1888, Abbott Laboratories is a research–based health care company that discovers, develops, manufactures and markets products that span the continuum of care – from prevention and diagnosis to treatment and cure.
Founded more than 100 years ago by Chicago physician Dr. Wallace C. Abbott, Abbott has emerged as one of the world's top health care companies. Today, Abbott discovers, develops, manufactures, and markets products and services that span the continuum of care – from prevention and diagnosis, to treatment and cure. Abbott casts a keen focus on areas with the greatest unmet medical need, such as oncology, infectious diseases, diabetes, obesity, immunology and cardiovascular disease.
II. Tricor Medication
Tricor medication (Fenofibrate) is used with diet changes (restriction of cholesterol and fat intake) to reduce the amount of cholesterol and triglycerides (fatty substances) in your blood. Accumulation of cholesterol and fats along the walls of your arteries (a process known as atherosclerosis) decreases blood flow and, therefore, the oxygen supply to your heart, brain, and other parts of your body. Lowering your blood level of cholesterol and fats may help to prevent heart disease, angina (chest pain), strokes, and heart attacks.
Cholesterol Reducing Drugs: Information
Cholesterol-reducing drugs are medicines that lower the amount of cholesterol (a fat-like substance) in the blood.
There are four different classes of cholesterol lowering drugs:
- Bile acid sequesterants are drugs that act by binding with the bile produced by the liver. Bile helps the digestion and absorption of fats in the intestine. By blocking the digestion of fats, bile acid sequesterants prevent the formation of cholesterol. Drugs in this class include: cholestyramine (Questran); colestipol (Colestid); and colesevalam (Welchol).
- HMG-CoA inhibitors, often called "statins," are drugs that block an enzyme called "3-hydroxy-3-methyl-glutaryl-coenzyme A reductase." This blocks one of the steps in converting fat to cholesterol. These are the most effective cholesterol lowering agents available and in recent years have received increased attention for their benefits beyond helping patients with high cholesterol. In 2003, researchers reported that people with heart failure but no coronary artery disease received benefits after only 14 weeks of statin therapy. In addition, some research has connected the drugs to reduced risk for depression and dementia. Drugs in this group include: atorvastatin (Lipitor); cerivastatin (Baycol); fluvastatin (Lescol); lovastatin (Mevacor); pravastatin (Pravachol); simvastatin (Zocor); and the newest approved drug rosuvastatin (Crestor).
- Fibric acid derivatives include clofibrate (Atromid-S); gemfibrozil (Lopid); and fenofibrate (Tricor). Although these drugs are less effective than the statins at lowering total cholesterol, they may be able to lower the low density lipoprotein (LDL) cholesterol while raising the high density lipoprotein (HDL) cholesterol. They probably act by inhibiting lipoprotein lipase activity.
- Niacin, or vitamin B-3, also is effective in lowering cholesterol levels. Although the normal vitamin dose of niacin is only 20 mg, the dose required to reduce cholesterol levels is at least 500 mg each day. Niacin probably helps reduce cholesterol by inhibiting very low density lipoprotein (VLDL) secretion in the bloodstream.
Cholesterol: Information
Cholesterol is a chemical that can do both good and harm in the body. On the good side, cholesterol plays important roles in the structure of cells and in the production of hormones. But too much cholesterol in the blood can lead to heart and blood vessel disease. To complicate matters, not all cholesterol contributes to heart and blood vessel problems.
One type, called high density lipoprotein (HDL) cholesterol, or "good cholesterol," actually lowers the risk of these problems. High-density lipoproteins (HDL) remove cholesterol from the bloodstream. The other type, low density lipoprotein (LDL) cholesterol, or "bad cholesterol," is the type that threatens people's health.
Low-density lipoproteins (LDL) deliver cholesterol to the body. To travel through the bloodstream, cholesterol must attach itself to a protein. The combination of a protein and a fatty substance like cholesterol is called a lipoprotein.
Many factors may contribute to the fact that some people have higher cholesterol levels than others. A diet high in certain types of fats is one factor. Medical problems such as poorly controlled diabetes, an under active thyroid gland, an overactive pituitary gland, liver disease or kidney failure also may cause high cholesterol levels. And some people have inherited disorders that prevent their bodies from properly using and eliminating fats. This allows cholesterol to build up in the blood.
Treatment for high cholesterol levels usually begins with changes in habits. By losing weight, stopping smoking, exercising more and reducing the amount of fat and cholesterol in the diet, many people can bring their cholesterol levels down to acceptable levels. However, some may need to use cholesterol-reducing drugs to reduce their risk of health problems.
While some cholesterol is needed for good health, too much cholesterol in your blood can raise your risk of having a heart attack or stroke.
The extra cholesterol in your blood may be stored in your arteries (blood vessels) and cause them to narrow. (This is called atherosclerosis.) Large deposits of cholesterol can completely block an artery, so the blood cannot flow through.
If an artery that supplies blood to your heart becomes blocked, a heart attack can occur. If an artery that supplies blood to your brain becomes blocked, a stroke can occur.
Cholesterol Levels:
Total cholesterol level
- Less than 200 is best.
- Between 200 to 239 is borderline high.
- 240 or more means you're at increased risk for heart disease.
LDL cholesterol levels
- Less than 130 is best.
- Between 130 to 159 is borderline high.
- 160 or more means you're at higher risk for heart disease.
HDL cholesterol levels
- Less than 40 means you're at higher risk for heart disease.
- 60 or higher reduces your risk of heart disease.
Side effects of Cholesterol Reducing drugs
- Gemfibrozil
Studies in animals and humans suggest that gemfibrozil increases the risk of some types of cancer. The drug may also cause gallstones or muscle problems. Patients who need to take gemfibrozil medicine should ask their physicians for the latest information on its benefits and risks.
Patients taking gemfibrozil medicaine should check with a physician immediately if any of these side effects occur: fever or chills
- severe stomach pain with nausea and vomiting
- pain in the lower back or side
- pain or difficulty when urinating
- cough or hoarseness
- HMG-CoA reductase inhibitors
These drugs may damage the liver or muscles. Patients who take the drugs should have blood tests to check for liver damage as often as their physician recommends. Any unexplained pain, tenderness or weakness in the muscles should be reported to the physician at once.
- All cholesterol-reducing drugs
Minor side effects such as heartburn, indigestion, belching, bloating, gas, nausea or vomiting, stomach pain, dizziness and headache usually go away as the body adjusts to the drug and do not require medical treatment unless they continue or they interfere with normal activities.
Patients who have constipation while taking cholesterol-reducing drugs should bring the problem to a physician's attention as soon as possible.
Additional side effects are possible. Anyone who has unusual symptoms while taking cholesterol-reducing drugs should get in touch with his or her physician.
