CHOLVASTIN tablets belong to a group of lipid-lowering medicines called HMG-CoA reductase inhibitors (commonly known as “statins”). They work by lowering lipids (fats) such as cholesterol and triglycerides in your blood when non-medicinal measures, such as a low-fat diet, exercise and lifestyle changes, alone have failed.
Cholesterol is a naturally occurring substance in the body necessary for normal growth. However, if there is too much cholesterol in your blood, it can get deposited along the walls of the blood vessels leading to narrowing and even blocking of these vessels (atherosclerosis). This is one of the common causes of heart problems such as chest pain (angina) and heart attack (myocardial infarction). High cholesterol levels have been shown to be associated with increased risk of heart disease. Other factors including high blood pressure, high blood sugar (diabetes), increased weight, lack of exercise and smoking further add to the risk of heart disease. High cholesterol levels in the blood can be brought down and kept down with dietary modifications, exercise and medicines.
CHOLVASTIN tablets are used for one or more of the following:
- If you already have heart disease and raised levels of cholesterol, pravastatin will help reduce your chances of having another heart attack, or a stroke. It will reduce your chances of requiring a procedure (such as coronary artery bypass grafting and percutaneous transluminal coronary angioplasty) to increase the blood flow to your heart, and will slow down any further narrowing of your arteries.
- If you do not have heart disease but just raised levels of cholesterol, pravastatin will help prolong your life, reduce the risk of your having a heart attack or requiring a procedure to increase the blood flow to your heart.
- If you have a condition known as primary hypercholesterolaemia, pravastatin will help bring down the cholesterol levels in your blood.
There is no evidence that CHOLVASTIN tablets are addictive.
CHOLVASTIN tablets are not expected to affect your ability to drive a car or operate machinery.
