Which medication is identified as a fibric acid derivative (fibrate)?

• A. Gemfibrozil
• B. Ezetimibe
• C. Niacin
• D. Colesevelam

Answer: (A)

Gemfibrozil is recognized as a fibric acid derivative, commonly referred to as a fibrate. Fibrates primarily work by activating peroxisome proliferator-activated receptors (PPARs), leading to a reduction in triglyceride levels and an increase in high-density lipoprotein (HDL) cholesterol. They are particularly effective in treating hypertriglyceridemia and can also modestly lower low-density lipoprotein (LDL) cholesterol levels. In contrast, the other options represent different classes of lipid-lowering agents. Ezetimibe works by inhibiting the absorption of cholesterol in the intestines, which helps to lower LDL cholesterol. Niacin, also known as vitamin B3, may increase HDL cholesterol and lower triglyceride levels, but it does not belong to the fibrate class. Colesevelam is a bile acid sequestrant that works by binding bile acids in the intestine and reducing cholesterol levels, but again, it is not a fibric acid derivative. Therefore, the classification of Gemfibrozil as a fibrate is firmly established based on its mechanism of action and clinical use in managing lipid profiles.
