Laropiprant
Laropiprant ( INN) 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.
Merck & Co. planned to market this combination under the trade names Cordaptive in the US and Tredaptive in Europe. Both brands contained 1000 mg of niacin and 20 mg of laropiprant in each tablet.
