The metabolic syndrome leads to cardiovascular disease and type 2 diabetes mellitus, through multiple risks, such as insulin resistance, dyslipidemia, hyperinsulinemia, and hypertension. It also represents a disorder of partial genetic background as mutations of the peroxisome proliferator-activated receptor-gamma (PPAR-γ). Thiazolidinedione agonists for the PPAR-γ system are effective in control of insulin resistance and diabetes. Telmisartan has a molecular structure that imparts partial agonist properties with the PPAR-γ molecule, which results in reductions in glucose and lipid metabolism. Administration of telmisartan to rats on a high-fat, high-carbohydrate diet leads to reductions in glucose, insulin, and triglyceride levels. The results imply that the ARB agent, telmisartan, could treat both the hemodynamic and metabolic aberrations seen in subjects with the metabolic syndrome, such as insulin resistance, glucose intolerance, and hypertension.
