Pharmacological interventions in the prevention of type 2 diabetes

Abstract

(1) Diabetes is a chronic disease whose incidence is increasing worldwide. The long-term complications of diabetes place a large health and economic burden onto individuals, their families and communities as a whole.(2) Guidelines on the prevention of diabetes recommend lifestyle changes such as smoking cessation and weight loss to decrease type 2 diabetes incidence in patients with impaired glucose tolerance or impaired fasting glucose.(3) The role of lifestyle changes and weight loss in preventing diabetes has been proven in large, randomized, controlled clinical trials. To date, the evidence in favor of pharmacological methods is less robust; however, encouraging results obtained so far suggest a promising future role for these agents.(4) Several oral hypoglycemic agents and the antiobesity drug orlistat have been shown to significantly decrease progression to diabetes. The role of other agents such as statins, oestrogen and antihypertensive agents remains to be clarified in additional well-designed studies of diabetes prevention.
