title: Tesaglitazar: a promising approach in type 2 diabetes.
abstract: While glycemic control remains the cornerstone of clinical management for patients with type 2 diabetes, the importance of a more comprehensive approach that addresses the multiple metabolic abnormalities seen in this population is now widely recognized. Abnormal lipid metabolism resulting in dyslipidemia contributes greatly to the markedly increased risks of cardiovascular disease observed in diabetic patients and in prediabetic patients with signs of insulin resistance. The peroxisome proliferator-activated receptors (PPARs) play a key role in the regulation of energy homeostasis and the coordination of inflammatory responses. As such, they are interesting targets for addressing both the glucose and lipid abnormalities associated with insulin resistance. The thiazolidinediones (TZDs), which activate PPARgamma, appear to improve glycemic control primarily by increasing peripheral insulin sensitivity and reducing hepatic glucose production, thereby helping to preserve beta-cell function. They have also demonstrated modest beneficial effects on some lipid parameters. The fibrate drugs, which activate PPARalpha, produce robust improvements in dyslipidemia, decrease atherosclerotic lesions and may have an effect on cardiovascular events, but do not affect glycemia. Theoretically, a compound targeting both the alpha and gamma PPARs simultaneously might combine the benefits of TZDs and fibrates. Tesaglitazar is a dual-acting PPARalpha/gamma agonist currently being investigated in phase III clinical trials as an alternative treatment for insulin resistance and the characteristic dyslypidemia of type 2 diabetes. This article reviews the available data on the clinical efficacy and safety of tesaglitazar in patients with type 2 diabetes and in individuals without diabetes but with insulin resistance.
