Cholesterol-lowering agents are medications designed to reduce levels of cholesterol in the blood. High cholesterol can lead to serious health issues, including heart disease and stroke. These agents work by various mechanisms, such as blocking the production of cholesterol in the liver or helping the body remove it from the bloodstream. Common types of cholesterol-lowering agents include statins, bile acid sequestrants, and PCSK9 inhibitors. Statins are the most widely prescribed and can significantly lower low-density lipoprotein (LDL) cholesterol, often referred to as "bad" cholesterol. Regular monitoring and lifestyle changes, such as diet and exercise, are also important in managing cholesterol levels.
