UKPDS and DCCT studies have demonstrated the critical role of tight glycaemic control to reduce the micro- and macro-vascular damage linked to diabetes. Unfortunately, the insulin requirement of type 2 diabetic patients remains elevated since 5 to 7% of these patients will required, yearly, a change from oral antidiabetic drug to insulin treatment to maintain a good glycaemic control. This manuscript is intended to review the currently available oral antidiabetic drugs, their benefits as well as potential arms and to propose a simplified therapeutic strategy in presence of type 2 diabetes.
