The inhibitors of 3-hydroxy-3-methylglutaryl-CoA reductase (or statins) are the most powerful drugs affecting lipid and lipoprotein levels in plasma. Results obtained from large controlled trials using simvastatin, pravastatin and lovastatin for the primary or secondary prevention of coronary heart disease have demonstrated that treatment with statins is associated with a significant reduction in coronary morbidity and mortality and in total mortality. This is probably due to a more general anti-atherogenic effect of these drugs beyond their lipid-lowering activity. Meta-analysis of data from these large trials indicates that statins have an impact also on the incidence of cerebrovascular events. Currently, six statins have been approved for therapeutic use in different countries. In spite of the similarities in their chemical structure and mechanisms of action, statins may differ in many aspects such as pharmacological properties (hydrophilic vs lipophilic, elimination half-life, cytochrome P450 metabolism, etc.), effects on lipid and other biochemical variables, or pleiotropic effects on different metabolic processes related to atherosclerosis (endothelial function, platelet aggregation, immune function, etc.). In general, the safety and tolerability profile for all statins currently in use is good with a < 2% incidence of undesirable effects.
