How does it work?
This medicine contains the active ingredient pravastatin sodium, which is a type of medicine called a statin. It works by reducing the production of cholesterol by the liver.
For the sake of simplicity, there are two sorts of cholesterol in the blood; 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, while HDL actually protects the arteries against this.
Pravastatin decreases the production of LDL cholesterol by blocking the action of the enzyme in the liver (called HMG-CoA reductase) that is responsible for its production. This decreases the amount of cholesterol in the liver cells, causing them to take up LDL cholesterol from the blood. The decreased cholesterol production and increased removal of LDL cholesterol from the blood ultimately results in lowered blood cholesterol levels.
Pravastatin 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. This results in lowered levels of 'bad fats' and raised levels of 'good fats' in the blood.
As the body produces most cholesterol at night, statins are generally more effective if taken at night. Pravastatin is used to reduce the blood levels of cholesterol and other fats when these cannot be lowered by diet and exercise alone. It is important to continue to follow a cholesterol-lowering diet and exercise regime while taking pravastatin.
Statins have an important role in the prevention of heart disease and stroke, because they reduce the risk of cholesterol being deposited in the major blood vessels of the heart and brain. This process is known as atherosclerosis or hardening of the arteries, and can reduce or block the blood and oxygen supply to organs such as the heart or brain. In severe cases this can result in a heart attack (myocardial infarction) or stroke.
Pravastatin is not only used to lower high cholesterol levels. In people with high cholesterol it also prevents the subsequent development of coronary heart disease and reduces the risk of heart problems, such as heart attacks. In people who already have hardended arteries it is used to slow the progression of atherosclerosis and reduce the risk of heart problems. In people with coronary heart disease who have already had a heart attack or unstable angina, pravastatin is also used to reduce the risk of further heart attacks or stroke and to improve survival.

Warning!
This medicine may very rarely have side effects on the muscles. For this reason you should inform your doctor immediately if you experience any muscular symptoms such as pain, tenderness, cramps, or weakness while taking this medicine, particularly if it is accompanied by a fever or feeling generally unwell. Your doctor may need to check for side effects on the muscles by taking a blood test to measure the level of a compound called creatinine kinase in your blood. If this is the case, the test should not be done following strenuous exercise.
You should have blood tests to monitor your liver function (liver function tests) before starting treatment and regularly throughout treatment with this medicine.
You should should continue eating a cholesterol-lowering diet during treatment with this medicine. Discuss this with your doctor.
