What class of medications is primarily used to lower cholesterol levels?

The class of medications primarily used to lower cholesterol levels is antihyperlipidemics. These medications work by various mechanisms to reduce lipid levels in the blood, particularly low-density lipoprotein (LDL) cholesterol, which is often referred to as "bad" cholesterol due to its association with an increased risk of cardiovascular disease.

Antihyperlipidemics encompass several different subclasses, including statins, fibrates, niacin, and bile acid sequestrants. Statins, for instance, inhibit an enzyme involved in cholesterol production in the liver, leading to decreased cholesterol levels in the bloodstream. This class of drugs is central in managing dyslipidemia and preventing complications such as heart attacks and strokes.

Understanding this mechanism helps to highlight the role of antihyperlipidemics in clinical practice, as they not only aim to normalize cholesterol levels but also contribute to overall cardiovascular health management. Other classes of medications listed, such as antihistamines, anticoagulants, and antidepressants, serve different purposes and are not focused on cholesterol management.
