Laropiprant, aslo known as MK-0524, was a drug used in combination with niacin to reduce blood cholesterol (LDL and VLDL) that is no longer sold, due to increases in side-effects with no cardiovascular benefit. Laropiprant itself has no cholesterol lowering effect, but it reduces facial flushes induced by niacin. Laropiprant acts as a selective DP1 antagonist, reducing the vasodilation.
