What is the main function of statins in the body?

Statins are primarily used to lower the levels of low-density lipoproteins (LDL) in the body. LDL is often referred to as "bad cholesterol" because high levels are associated with an increased risk of cardiovascular diseases, including heart attacks and strokes. Statins work by inhibiting an enzyme known as HMG-CoA reductase, which plays a central role in the biosynthesis of cholesterol in the liver. By reducing the production of cholesterol, statins lead to a decrease in LDL cholesterol levels in the bloodstream. This action helps in stabilizing plaque in the arteries and can contribute to overall cardiovascular health. The primary goal of using statins is to manage cholesterol levels effectively, thereby reducing the risk of heart disease.
