<p>Omega-3-acid ethyl esters reduce triglyceride production by the liver but this mechanism is not well understood. Omega-3-acid ethyl esters inhibit acyl-CoA: 1,2-diacylglycerol acyltransferase, reducing triglyceride synthesis and increasing paroxysmal beta-oxidation, which increases fatty aside metabolism. Omega-3-acid ethyl esters also inhibit the release of fatty acids by competing for enzymes involved in the synthesis of triglycerides, increase triglyceride clearance by increasing the activity of lipoprotein lipase, and decrease production of VLDL-C.</p>
