Overview

Icosapent ethyl, an ethyl ester of the omega-3 fatty acid eicosapentaenoic acid (EPA), is an antilipemic agent.

Icosapent ethyl is a purified preparation of eicosapentaenoic acid (EPA), an omega-3 fatty acid. EPA is a long-chain, polyunsaturated fatty acid (PUFA) that is obtained mainly from marine sources such as fatty fish (e.g., herring, mackerel, salmon, sardines, tuna). Icosapent ethyl is commercially available in the US as a prescription drug.

Each 1-g capsule of icosapent ethyl contains 1 g of a highly purified (at least 96%), esterified form of the omega-3 fatty acid EPA; icosapent ethyl does not contain docosahexaenoic acid (DHA).

The mechanism by which EPA and other omega-3 fatty acids reduce triglyceride concentrations is not completely understood; however, studies suggest that EPA reduces hepatic synthesis and/or secretion of very low-density lipoprotein (VLDL)-triglycerides and enhances triglyceride clearance from circulating VLDL particles. Omega-3 fatty acids may reduce the synthesis of VLDL-triglycerides or triglycerides by reducing the amount of substrate (fatty acids) available for triglyceride formation (i.e., by increasing beta-oxidation, decreasing delivery of free fatty acid to the liver, decreasing hepatic lipogenesis, increasing phospholipid synthesis, and/or inhibiting hormone-sensitive lipase in adipose tissue). In addition to reducing the amount of substrate available for triglyceride formation, omega-3 fatty acids may reduce triglyceride synthesis by limiting activity of key triglyceride-synthesizing enzymes (e.g., diacylglycerol O-acyltransferase, phosphatidate phosphatase).

Omega-3 fatty acids may enhance activity of lipoprotein lipase in peripheral adipose tissue, resulting in increased peripheral conversion of VLDL particles to LDL particles.

The mechanism of action of icosapent ethyl in reducing the risk of atherosclerotic cardiovascular disease (ASCVD) is not clear, but is likely to be multifactorial. The relatively modest effects of the drug on triglyceride concentrations and other atherogenic lipoproteins observed in clinical studies suggest that the cardiovascular benefits are attributed in part to other potential mechanisms (e.g., membrane stabilizing effects; anti-inflammatory, antithrombotic, or antiarrhythmic effects; reduction in coronary plaque progression).

Following oral administration, icosapent ethyl is de-esterified during absorption; the active metabolite, EPA, is absorbed in the small intestine and enters systemic circulation mainly by the thoracic duct lymphatic system. The majority of EPA circulating in plasma is incorporated in phospholipids, triglycerides, and cholesteryl esters, and less than 1% is present as the unesterified fatty acid. EPA is mainly metabolized in the liver by beta-oxidation similar to dietary fatty acids.

Cytochrome P-450 (CYP) isoenzymes play a minor role in the metabolism of EPA. The plasma elimination half-life of EPA is approximately 89 hours. Icosapent ethyl is not renally excreted.

USES: Icosapent ethyl is used along with certain other cholesterol medications ("statins" such as atorvastatin, simvastatin) to reduce the risk of heart attack, stroke, and certain types of heart problems that require treatment in a hospital. It is also used along with a proper diet to help lower fats (triglycerides) in the blood. Icosapent ethyl is a type of omega-3 fatty acid, a fat found in fish oil.

It is thought to work by decreasing the amount of triglycerides made by the body. In addition to eating a proper diet (such as a low-cholesterol/low-fat diet), other lifestyle changes that may help this medication work better include exercising, losing weight if overweight, and stopping smoking. Consult your doctor for more details.
