Which of the following drugs is classified as a fibrate for treating hyperlipidemia?

1. TriCor

2. Colestid

3. Pravachol

4. Zocor

The correct answer is: TriCor

The drug classified as a fibrate for treating hyperlipidemia is TriCor. Fibrates are a group of medications that primarily lower triglyceride levels and can also increase high-density lipoprotein (HDL) cholesterol. They work by activating peroxisome proliferator-activated receptors (PPARs), which leads to increased lipolysis and reduced production of triglyceride-rich lipoproteins. TriCor, specifically, is used to treat high cholesterol and triglyceride levels, often used in conjunction with lifestyle changes. It is distinct in its action compared to other options listed. Colestid is a bile acid sequestrant, which works differently by binding bile acids in the intestines, thus preventing their reabsorption and promoting cholesterol elimination through the feces. Pravachol and Zocor are statins, a class of drugs that inhibit cholesterol synthesis in the liver, primarily lowering low-density lipoprotein (LDL) cholesterol. Each of these alternatives operates through different mechanisms and classifications, which sets TriCor apart as a fibrate for hyperlipidemia treatment.
