Statins are a class of drugs commonly used to lower cholesterol levels in the blood. They work by blocking an enzyme in the liver that is responsible for producing cholesterol. Statins are often prescribed to individuals at risk for heart disease or stroke due to high cholesterol levels. Research on statins has focused on their efficacy in reducing the risk of cardiovascular events, such as heart attacks and strokes, as well as potential side effects and interactions with other medications. Additionally, there is ongoing research on the use of statins for other conditions, such as preventing inflammation and improving cognitive function.
