1. What Simvastatin Tablets are and what they are used for
This medicine contains simvastatin which belongs to a group of drugs known as HMG-CoA reductase inhibitors. These are used to reduce the amount of cholesterol and fatty substances called triglycerides in your blood. Cholesterol is vital to the normal functioning of the body, but if levels of cholesterol in the bloodstream get too high it can be deposited on the walls of the arteries, where it builds up eventually leading to the blocking of the blood vessel. Only a small amount of cholesterol comes from our diet. Nearly all of the cholesterol in our bodies is made by our own livers and is produced mostly at night.
If you have had a blood test which shows that you have too much fat (including cholesterol) in your blood, this medicine should lower these levels which will reduce the risk of developing heart disease. If you have coronary heart disease, simvastatin will lessen the risk of heart attack or of needing heart surgery.
