Newer pharmaceutical agents to treat lipid disorders.
The National Cholesterol Education Program Adult Treatment Panel III guidelines and the results of the Heart Protection Study have provided a stronger rationale to more aggressively treat high-risk patients to a low-density (LDL) cholesterol goal of less than 100 mL/dL. Two new therapies, ezetimibe and rosuvastatin, have recently been added to the lipid-lowering armamentarium to improve guideline adherence. Ezetimibe, a novel cholesterol absorption inhibitor, lowers LDL by 18% to 20% and can be used safely in combination with statins. Adding ezetimibe to a statin is comparable with the LDL-lowering efficacy of tripling the dose of the statin. Rosuvastatin is a highly efficacious statin providing 8% greater LDL reduction than equivalent doses of atorvastatin, and the starting dose of 10 mg/d provides nearly a 50% reduction in LDL cholesterol. There are several investigational drugs in development for the prevention and treatment of atherosclerosis. Of these investigational drugs, the most promising are the cholesterol ester transfer protein inhibitors, which have the potential to significantly raise high-density lipoprotein cholesterol and acetyl-coenzyme A: cholesterol acyltransferase inhibitors, which may directly inhibit the progression of atherosclerosis.
