OMEGA-3-ACID ETHYL ESTERS

Cardiovascular Approved 2014-04-07

Omega-3-acid ethyl esters are indicated as an adjunct to diet to reduce triglyceride (TG) levels in adult patients with severe hypertriglyceridemia (≥500 mg/dL). Clinical management should first include a specialized lipid-lowering diet, exercise, and weight loss, as well as the management of contributing factors such as diabetes, hypothyroidism, or medications known to exacerbate hypertriglyceridemia (e.g., beta-blockers, thiazides, estrogens). **Limitations of Use:** The effect of this medication on the risk of pancreatitis and its impact on cardiovascular mortality and morbidity have not been determined.

How OMEGA-3-ACID ETHYL ESTERS Works

The exact mechanism of action is not completely understood but involves several hepatic pathways to reduce triglyceride synthesis. Key mechanisms include the inhibition of acyl-CoA:1,2-diacylglycerol acyltransferase, increased mitochondrial and peroxisomal β-oxidation, and decreased hepatic lipogenesis. Additionally, EPA and DHA serve as poor substrates for the enzymes responsible for triglyceride synthesis and inhibit the esterification of other fatty acids, while potentially increasing plasma lipoprotein lipase (LPL) activity. These combined effects result in a reduction of VLDL-TG secretion into the blood.
