All About Cholesterol-Lowering Drugs

Making healthy lifestyle changes alone is enough to help some people reach the cholesterol goals prescribed by their doctor. Others, however, need to take a cholesterol-lowering medication, as well.

According to the American Heart Association, there are five main types:

  • Statins (atorvastatin, fluvastatin, lovastatin, pravastatin, rosuvastatin, simvastatin, pitavastatin). These drugs work mainly by lowering LDL ("bad") cholesterol. They typically reduce LDL by around one-third. They can also help raise HDL ("good") cholesterol and lower triglycerides (other blood fats). Statins work by slowing down the body's production of cholesterol. They also increase the liver's ability to remove LDL from the blood. In research involving people who already had heart disease, statins led to significant reductions in heart attacks and heart disease deaths. They may also prevent first heart attacks in people who are at high risk of developing heart disease.

  • Bile acid sequestrants (cholestyramine, colesevelam, colestipol). These drugs also lower LDL, although somewhat less than statins. These medications work by binding with bile acids in the intestines and forcing them to be eliminated in the stool rather than absorbed. The liver needs cholesterol to make bile acids, so as more bile is lost, more cholesterol from your body is used up to make additional bile. 

  • Nicotinic acid (niacin). This B vitamin increases HDL and lowers LDL and triglycerides when taken at levels higher than dietary requirements. Nicotinic acid is sold as both a prescription drug and a dietary supplement, but only the prescription form should be used for cholesterol lowering.

  • Fibrates (gemfibrozil, fenofibrate). These drugs help mainly by lowering triglycerides. They may also lead to modest improvements in LDL and HDL levels.

  • Selective cholesterol absorption inhibitors (ezetimibe). This drug lowers cholesterol by reducing the amount of cholesterol absorbed by the intestines. Ezetimibe, bile acid sequestrants, or nicotinic acid are sometimes combined with a statin to help people reach their LDL cholesterol-lowering goals.
