Developing therapies for the metabolic syndrome: challenges, opportunities, and… the unknown.

Metabolic syndrome refers to a clustering of established and emerging cardiovascular disease risk factors within a single individual. The established risk factors, such as obesity, diabetes, dyslipidaemia and hypertension, and other emerging risk factors are closely related to central obesity (especially intra-abdominal adiposity) and insulin resistance. However, debate continues about the very existence of the metabolic syndrome. Despite the controversies, many existing and new therapies are targeting the metabolic syndrome and component risk factors. To date, no therapies have been approved specifically for treating the metabolic syndrome. In this article some of the challenges and opportunities in developing therapies for the metabolic syndrome are discussed.
