United Kingdom Prospective Diabetes Study: implications for metformin
Clifford J Bailey, Ian W Campbell

One of the purposes of the United Kingdom Prospective Diabetes Study (UKPDS) was to compare the efficacy of different antidiabetic drugs in the long-term treatment of type 2 diabetes. In overweight type 2 patients, use of metformin as the initial antidiabetic drug therapy reduced overall mortality and reduced various long-term complications to a greater extent than other first-line treatments tested (sulphonylureas and insulin) whilst controlling hyperglycaemia to a similar extent. The benefit of early intervention with metformin may be due, at least in part, to its actions against insulin resistance and associated cardiovascular risk factors. Thus the UKPDS has provided evidence that early intensive glucose control with metformin in overweight type 2 diabetic patients is a particularly effective approach to reduce vascular complications and improve survival.
