Documented Uses

• So far only one cholesterol absorption inhibitor has reached the market: Ezetimibe. Although the detailed mechanism of action is not yet quite clear, /Ezetimibe/ inhibits the intestinal absorption of cholesterol and as a consequence lowers total plasma cholesterol.
• Use (kg; approx.) in Germany (2009): >1000
• Consumption (g per capita; approx.) in Germany (2009): 0.0122
• Preparation: S.B. Rosenblum et al., WO 9508532; eidem US 5767115 (1995, 1998 both to Schering)
• Ezetimibe is a dyslipidemic agent used to treat people with hyperlipidemia. It was FDA-approved in 2002. Ezetimibe is the most commonly used nonstatin agent, which lowers LDL-C levels by 13% to 20%. Ezetimibe is an inhibitor of intestinal cholesterol absorption. It is indicated to reduce total cholesterol, low-density lipoprotein (LDL), apolipoprotein B (apo B), and non-high-density lipoprotein (HDL) in patients with primary hyperlipidemia, mixed hyperlipidemia, familial hypercholesterolemia (HoFH), and homozygous
• Ezetimibe is an inhibitor of intestinal cholesterol absorption that is widely used in the therapy of hypercholesterolemia, usually in combination with other agents. Ezetimibe therapy is associated with a low rate of serum aminotransferase elevations and clinically apparent liver injury due to ezetimibe occurs, but is rare.
