Contains active ingredient : Atorvastatin which is a statin medicine used to lower cholesterol and triglyceride levels and reduce the risk of heart disease. Read on for advice on its use, warnings and side effects.
What is it used for?
Atorvastatin is used to lower high levels of total cholesterol, LDL cholesterol and other fats called triglycerides and apolipoprotein B in the blood. It is prescribed for adults and children over 10 years with primary hypercholesterolaemia, familial hypercholesterolaemia or mixed hyperlipidaemia. Atorvastatin is used when a low-fat diet and lifestyle changes such as increased exercise have not reduced cholesterol enough.
Atorvastatin is also used to help prevent cardiovascular events such as angina, heart attacks, strokes or needing heart bypass surgery, in people with a high risk of heart disease. These include smokers, people who are overweight or obese, and people with diabetes, high blood pressure or a close family history of heart disease. Atorvastatin can be used for this purpose even if your cholesterol levels are normal.
How does it work?
For the sake of simplicity, there are two sorts of cholesterol; a 'bad' sort called low density lipoprotein (LDL) and a 'good' sort called high density lipoprotein (HDL). LDL is deposited in the arteries and increases the risk of heart disease by clogging and narrowing the arteries (atherosclerosis), while HDL actually protects the arteries against this.
Atorvastatin works by reducing the production of LDL cholesterol by the liver. This has a knock-on effect of making the liver cells take up LDL cholesterol from the blood. Atorvastatin also causes a small decrease in the production of other 'bad fats' in the blood called triglycerides, and a small increase in the level of HDL cholesterol. The overall result is lowered levels of 'bad fats' and raised levels of 'good fats' in the blood.
Statins like atorvastatin have an important role in the prevention of coronary heart disease and stroke, because they reduce the risk of excess cholesterol being deposited in the major blood vessels of the heart and brain. Any blockage in these blood vessels limits the amount of blood and therefore oxygen that can be carried to the heart or brain. In the heart this can cause chest pain (angina) and in severe cases can result in a heart attack (myocardial infarction), while in the brain it can cause a stroke.
Atorvastatin slows down hardening of the arteries, regardless of your initial cholesterol level. It reduces the risk of needing procedures to improve blood supply to the heart, such as a balloon dilation of an artery or a heart bypass graft. It also reduces the risk of heart attack, stroke and death from heart disease.
