Fenofibric acid is primarily used in the treatment of hyperlipidemia, a condition characterized by abnormally high levels of lipids in the blood. It works by activating peroxisome proliferator-activated receptor alpha (PPARα), which helps reduce triglycerides and increase high-density lipoprotein (HDL) cholesterol levels. This makes it effective in managing conditions like hypertriglyceridemia and mixed dyslipidemia, often in combination with other lipid-lowering agents such as statins. Additionally, it is used to lower the risk of cardiovascular events in patients with type 2 diabetes and other metabolic disorders. Its ability to improve lipid profiles contributes to better overall cardiovascular health.
