From Motley Fool:
Campbell: Amarin markets a drug called Vascepa. Vascepa is a purified omega three fatty acid. We'll call it EPA. It's been on the market since 2012 for use in reducing triglycerides, fat in the blood, in patients that have very high triglyceride readings, greater than 500 milligrams per deciliter. The approval in the very high population, however, only scratches the surface of the addressable market. There are literally tens of millions of patients that have elevated triglyceride levels.
