Patient Education

Fluvastatin


Fluvastatin is used together with diet, weight loss, and exercise to reduce the risk of heart attack and stroke and to decrease the chance that heart surgery will be needed in people who have heart disease or who are at risk of developing heart disease. Fluvastatin is also used to decrease the amount of fatty substances such as low-density lipoprotein (LDL) cholesterol ('bad cholesterol') and triglycerides in the blood and to increase the amount of high-density lipoprotein (HDL) cholesterol ('good cholesterol') in the blood. Fluvastatin may also be used to decrease the amount of cholesterol and other fatty substances in the blood in children and teenagers 10 to 17 years of age who have familial heterozygous hypercholesterolemia (an inherited condition in which cholesterol cannot be removed from the body normally). Fluvastatin is in a class of medications called HMG-CoA reductase inhibitors (statins). It works by slowing the production of cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body. 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 with fluvastatin has been shown to prevent heart disease, angina (chest pain), strokes, and heart attacks.

Statins


Statins are drugs used to lower cholesterol. Your body needs some cholesterol to work properly. But if you have too much in your blood, it can stick to the walls of your arteries and narrow or even block them.

If diet and exercise don't reduce your cholesterol levels, you may need to take cholesterol medicine. Often, this medicine is a statin. Statins interfere with the production of cholesterol in your liver. They lower LDL (bad) cholesterol levels and raise HDL (good) cholesterol levels. This can slow the formation of plaques in your arteries.

Statins are relatively safe for most people. But they are not recommended for pregnant patients or those with active or chronic liver disease. They can also cause serious muscle problems. Some statins also interact adversely with other drugs. You may have fewer side effects with one statin drug than another.

Researchers are also studying the use of statins for other conditions.
