How do other lipid-lowering agents work?

Lipid-lowering agents are medications used to reduce the risk of heart attacks, by lowering abnormally high levels of blood fats (lipids) including cholesterol and triglycerides, which can build up in the arterial walls, obstructing free blood flow. Other lipid-lowering agents are medications that are not categorized into any specific class of lipid-lowering agents.

Other lipid-lowering agents work in different ways to reduce lipid levels, and include the following:

  • Icosapent: Icosapent is a synthetic derivative of eicosapentaenoic acid (EPA), one of the three main omega-3 fatty acids. Icosapent reduces blood fat levels by reducing the synthesis and/or secretion of very-low-density lipoprotein triglycerides (VLDL-TG) in the liver and enhances the clearance of triglycerides from circulating VLDL particles.
  • Icosapent inhibits acyl-CoA:1,2-diacylglycerol acyltransferase (DGAT), a protein essential for triglyceride synthesis in the liver, and enhances the activity of lipoprotein lipase, an enzyme that degrades triglycerides in the bloodstream. Icosapent may also increase the breakdown of fats in a process known as beta-oxidation in the liver, to produce energy.
  • Niacin (vitamin B3): Niacin is a water-soluble vitamin and a component essential for lipid metabolism, in addition to other functions. Niacin lowers blood lipid levels by inhibiting the release of free fatty acids from fat tissue, increasing the activity of lipoprotein lipase, and decreasing the hepatic synthesis of VLDL and LDL.
  • Omega-3 fatty acids: Omega 3 fatty acids are ethyl esters containing two types of fatty acids, eicosapentaenoic acid and docosahexaenoic acid (DHA). Omega-3 fatty acids reduce the synthesis of triglycerides in the liver, increase beta-oxidation in the liver and increase the activity of lipoprotein lipase and degradation of triglycerides in the bloodstream.
  • Omega-3 carboxylic acids: Omega 3 carboxylic acids are free fatty acids containing EPA and DHA, and work similarly to omega-3 fatty acid ethyl esters. Both forms of omega-3 fatty acids are derived from fish oil. Currently, Omega-3 carboxylic acids production has been discontinued by the manufacturer and the product is not available in the US.
