Drug treatment of patients with hyperlipoproteinaemia is indicated to reduce the risk of atherosclerosis in patients with increased concentrations of atherogenic lipoproteins, and to lower the plasma concentrations of triglyceride-rich lipoproteins in patients with severe hypertriglyceridaemia who are at risk of abdominal pain and pancreatitis. Such therapy should be initiated only after satisfactory exclusion of secondary causes of hyperlipoproteinaemia, and should be regarded as an adjunct to rather than a substitute for appropriate dietary therapy. Drug therapy should be strongly considered in those patients with concentrations of atherogenic lipoproteins which exceed the 90th to 95th percentile for age. In patients with increased plasma concentrations of low density lipoproteins (LDL), agents which enhance the rate of LDL catabolism (cholestyramine and colestipol) or reduce the rate of LDL synthesis [e.g. nicotinic acid (niacin)] are the 'drugs of choice'. For those patients with concurrent hypertriglyceridaemia, nicotinic acid is the preferred initial drug, and in both patient groups combined drug therapy is often necessary to attain optimal reductions in LDL cholesterol concentrations. Clofibrate remains the 'drug of choice' for the rare patient with type III hyperlipoproteinaemia, whereas the newer agent gemfibrozil should be used in patients with plasma triglyceride concentrations above 1000 mg/dl who are at increased risk of abdominal pain and pancreatitis. Although currently limited to investigational use, mevinolin and related compounds, which are specific inhibitors of the rate-limiting enzyme in cholesterol biosynthesis (HMG Co-A reductase), offer considerable promise in the therapy of patients with primary hypercholesterolaemia due to elevated levels of LDL cholesterol.

Endpoint studies have been performed with fibrates in coronary heart disease since 1971. The results have been confusing - starting with initial benefits in small studies, but contradicted by either minimal benefits in the Coronary Drug Project or adverse noncardiovascular (non-CV) effects in the World Health Organization Clofibrate Study. Fibrates returned for patients with low HDL-C and low LDL-C after a 25% event reduction were seen in the Veterans Affairs HDL Intervention Trial. The greater prominence ascribed to the lipid triad of the metabolic syndrome and the increasing prevalence of diabetes increased the topicality of fibrates given their main action of converting small dense to light buoyant LDL. The Fenofibrate Intervention in Event Lowering in Diabetes (FIELD) Study has carried on the tradition. Fenofibrate therapy in 9795 patients comprising a mixed low-risk primary and a medium-risk secondary prevention cohort resulted in an 11% reduction in coronary events (p = 0.16), a similar but significant reduction in CV events (p = 0.04; number needed to treat = 70). The benefits were concentrated in primary prevention and on nonfatal myocardial events, but the study was confounded by asymmetrical statin drop-in due to the LDL-C-lowering effect of fenofibrate. Safety was generally good, including in combination with statins, but old concerns about sudden death, pancreatitis and venous thrombosis returned. Unexpected benefits were seen with fenofibrate on microvascular endpoints including microalbuminuria and retinopathy. Fenofibrate is a reasonable second-line therapy for dyslipidaemia in diabetes and safe in combination therapy. Its benefits on microvascular disease and in combination therapy require further confirmation.
