In which way do cholesterol-lowering medications primarily work?

Cholesterol-lowering medications primarily work by lowering low-density lipoprotein (LDL) levels, which is crucial for managing and reducing the risk of cardiovascular diseases. LDL is often referred to as "bad cholesterol" because high levels of it can lead to plaque buildup in the arteries, increasing the risk of heart attack and stroke.

Medications such as statins specifically target and inhibit an enzyme involved in cholesterol production in the liver, leading to a decrease in LDL cholesterol levels in the blood. This reduction helps to prevent the progression of atherosclerosis and improves overall cardiovascular health.

While other mechanisms such as inhibiting cholesterol absorption, increasing bile acid excretion, or raising high-density lipoprotein (HDL) levels are also aspects of some cholesterol-lowering therapies, the primary and most well-studied impact of these medications is their ability to significantly lower LDL cholesterol levels. This action is central to the therapeutic goals in treating dyslipidemia and preventing cardiovascular events.
