Micronized fenofibrate (Tricor - Abbott), a fibric acid derivative structurally similar to clofibrate (Atromid-S, and others) and gemfibrozil (Lopid, and others), has been approved by the FDA for treatment of hypertriglyceridemia. Increased serum triglyceride concentrations have been associated with an increased risk of coronary heart disease (J Jeppesen et al, Circulation, 97:1029, 1998).

Fibrates, niacin and fish oil are promoted for treatment of hypertriglyceridemia. HMG-CoA reductase inhibitors (statins) can lower elevated serum concentrations of triglycerides, but less so than fibrates, niacins or fish oil. Lifestyle changes such as weight reduction, exercise and decreasing alcohol intake can also lower serum triglyceride levels and should be tried first.

Cholesterol management guidelines from the American College of Cardiology/American Heart Association Task Force were last published in 2019.

A highly concentrated omega-3 polyunsaturated fatty acid (PUFA) preparation (Omacor - Reliant) has been approved by the FDA as an adjunct to diet for treatment of very high plasma triglyceride concentrations (>=500 mg/dL). Omacor is a combination of the ethyl esters of icosapentaenoic (EPA) and docosahexaenoic (DHA) acids. It is the first drug derived from omega-3 PUFAs to be sold by prescription.

The FDA recently approved three new drugs for treatment of hyperlipidemia. Ezetimibe (ez et' i mibe; Zetia) is the first in a new class of drugs that inhibit intestinal absorption of cholesterol. Extended-release lovastatin (Altocor) is a new formulation of lovastatin (Mevacor, and others). Extended-release niacin plus (immediate-release) lovastatin (Advicor) is the first fixed-dose combination of lipid-lowering drugs.

Icosapent ethyl (Vascepa [vas EE puh] – Amarin), the ethyl ester of eicosapentaenoic acid (EPA), has been approved by the FDA as an adjunct to diet for treatment of severe hypertriglyceridemia (≥500 mg/dL). Vascepa is the second omega-3 polyunsaturated fatty acid (PUFA) product to become available by prescription for this indication; Lovaza (formerly Omacor), which is a combination of the ethyl esters of EPA and docosahexaenoic acid (DHA), was the first. Many omega-3 PUFA-containing fish oil capsules are sold over the counter as dietary supplements.

The FDA has approved the oral adenosine triphosphate-citrate lyase (ACL) inhibitor bempedoic acid for use alone (Nexletol – Esperion) and in a fixed-dose combination with the cholesterol absorption inhibitor ezetimibe (Nexlizet) as an adjunct to diet and maximally tolerated statin therapy in adults with heterozygous familial hypercholesterolemia (HeFH) or established atherosclerotic cardiovascular disease (ASCVD) who require additional lowering of LDL-cholesterol (LDL-C). Bempedoic acid is the first ACL inhibitor to be approved in the US.

The FDA has approved the marketing of fenofibric acid (Trilipix - Abbott) to reduce triglycerides and increase HDL-C in patients with mixed dyslipidemia on optimal doses of a HMG-CoA reductase inhibitor (statin) who have, or have risk factors for, coronary heart disease. It is the first fibrate approved by the FDA specifically for combined use with a statin. Trilipix is also approved as monotherapy for hypertriglyceridemia, hypercholesterolemia and low HDL-C. The patent for Tricor, Abbott's older formulation of fenofibrate, will expire in 2011.

Full-page newspaper advertisements are urging patients with high cholesterol levels who are stopping Baycol (cerivastatin) to ask their doctors about Pravachol (pravastatin), Lipitor (atorvastatin), Zocor (simvastatin) or Lescol (fluvastatin). Some advertisements come with a coupon for free medication. Lovastatin, which is available generically, has not appeared in similar advertisements. Cerivastatin was withdrawn from the market on August 8 because of post-marketing reports of 31 cases of fatal rhabdomyolysis.

The FDA has announced changes in the labeling of simvastatin to reduce the risk of myopathy. These changes include limiting the use of the 80-mg maximum dose to patients who have been taking it for 12 months or more without evidence of myopathy and new recommendations for use of simvastatin with other drugs. Simvastatin is available alone (Zocor, and others) and in combination with ezetimibe (Vytorin) and with niacin (Simcor).
