Whats the difference between Statins and Fibrates?

Statins are also known as HMG-CoA reductase inhibitors. They are the most effective drugs in lowering LDL cholesterol. They inhibit HMG-CoA reductase (3-hydroxy-3-methylglutaryl coenzyme A reductase) an enzyme involved in the synthesis of cholesterol, especially in the liver. Decreased cholesterol production leads to an increase in the number of LDL membrane receptors, which increases clearance of LDL cholesterol from circulation.

Fibrates are regarded as broad-spectrum lipid lowering drugs. Their main action is to decrease triglyceride levels but they also tend to reduce LDL cholesterol and help to raise HDL cholesterol. Mechanism of action is not well established. Apparently it decreases plasma levels of triglycerides by decreasing their synthesis. Also reduces plasma levels of VLDL cholesterol by reducing its release into the circulation and increasing catabolism.
