Summary The efficacy and safety of metformin in the treatment of obese, non-insulin-dependent, diabetic subjects poorly controlled by insulin after secondary failure to respond to sulphonylureas has been investigated. Fifty insulin-treated, obese diabetics participated in this prospective, randomised double-blind six-month trial. After a four-week run-in period, during which all patients were given placebo (single-blind), patients were randomly assigned to continue to receive placebo or to active treatment with metformin. At six months, there was a relevant and significant improvement in glycaemic control in diabetics receiving the combined insulin-metformin treatment (decrease in glucose −4.1 mmol·l−1; glycosylated haemoglobin A1 decrease −1.84%). No significant changes were seen in diabetics receiving insulin and placebo. There was a significant decrease in blood lipids (trygliceride and cholesterol), an increase in HDL-cholesterol and a reduction in blood pressure in diabetics taking metformin. These postive findings were most marked in the 14 diabetics who experienced a good response to metformin (glucose profile 〈10 mmol·l−1), and were less marked but still significant in the remaining 13 diabetics, whose response to therapy was not so good (glucose profile 〉10 mmol·l−1). The fasting insulin level was significantly lower after six months of combined insulin-metformin treatment as shown by a 25% reduction in the daily dose of insulin (−21.6 U/day). Metformin was well tolerated by all diabetics. Combining metforming with insulin in obese, insulin-treated and poorly controlled diabetics may represent a safe strategy to achieve better glycaemic control with a reduction in certain metabolic risk factors associated with the increased incidence of cardiovascular disease in diabetes mellitus.
