An overview of rosuvastatin/ezetimibe association for the treatment of hypercholesterolemia and mixed dyslipidemia.

: Although statin therapy is a powerful lipid-lowering strategy, only one-fifth of statin users currently reach their lipid goals. In addition, statin treatment alone has relatively low efficacy in reducing other lipid fractions than low-density lipoprotein-cholesterol (LDL-C). In such cases, most guidelines recommend adding the cholesterol absorption inhibitor ezetimibe.: This paper summarizes the main pharmacological characteristics of rosuvastatin and ezetimibe (mechanism of action, metabolism), their lipid-lowering and pleiotropic effects, with particular attention to the clinical effects of the combined drugs in hypercholesterolemia and mixed dyslipidemia patients (such as the ones affected by diabetes mellitus and Acquired Immune Deficiency Syndrome (AIDS)).: The additive effect of rosuvastatin and ezetimibe helps to reach lipid goals in a large number of high-risk patients, while avoiding some safety issues related to high dosages of intensive statin therapy. Patients with diabetes receive additional benefits from ezetimibe as they seem to absorb cholesterol more effectively than non-diabetic ones, because of increased NPC1L1 gene expression. Ezetimibe augments rosuvastatin triglyceride-lowering and anti-inflammatory effects, as well. Taking into account its excellent safety profile and lack of clinically relevant drug-drug interactions, the rosuvastatin/ezetimibe association is a valuable alternative to statin dose uptitration.
