What is the main purpose of using statins in medication therapy?

The primary purpose of using statins in medication therapy is to lower cholesterol levels, particularly low-density lipoprotein (LDL) cholesterol, which is often referred to as "bad" cholesterol. Elevated LDL cholesterol is a significant risk factor for cardiovascular diseases, including heart attacks and stroke. Statins work by inhibiting an enzyme in the liver that is crucial for the production of cholesterol, thereby reducing the overall cholesterol levels in the bloodstream.

By effectively lowering cholesterol, statins can help decrease the risk of cardiovascular events by improving endothelial function and stabilizing atherosclerotic plaques. This positive impact on cardiovascular health is why statins are commonly prescribed for individuals with high cholesterol or those at risk for cardiovascular disease.
