Pharmacotherapy of dyslipidemia.
Reducing elevated levels of low-density-lipoprotein cholesterol (LDL-C) significantly reduces the incidence of coronary heart disease (CHD) events and mortality in hypercholesterolemic patients. CHD risk reduction is proportional to LDL-C reduction. Despite this knowledge, many physicians are not applying existing treatment guidelines to the extent required to achieve target LDL-C levels. Target LDL-C levels are not achievable for most patients without drug therapy. Based on their lipid-lowering abilities, safety, and tolerability profiles, the HMG-CoA reductase inhibitors (statins) are the first-line pharmacotherapeutic agents for hypercholesterolemia. The ability of statins to reduce CHD events and total mortality in primary- and secondary-prevention patients also supports this assertion. For combined dyslipidemia, statin monotherapy is a reasonable initial approach in patients with moderate hypertriglyceridemia because statins effectively lower both LDL-C and triglycerides. Fibrates or niacin are effective therapies for severe hypertriglyceridemia. Resins are moderately effective in isolated hypercholesterolemia, and are a useful alternative to statins in pregnant women or patients with liver disease. For severe hyperlipidemia that does not respond to single drug therapy, combination drug therapy may be required. This article reviews the various manifestations of dyslipidemia and assesses the most efficacious treatments.
