Durable efficacy of metformin/glibenclamide combination tablets (Glucovance) during 52 weeks of open-label treatment in type 2 diabetic patients with hyperglycaemia despite previous sulphonylurea monotherapy.
Oral anti-diabetic combinations that address insulin resistance and beta-cell dysfunction (e.g. metformin and glibenclamide) represent a rational therapeutic option for patients uncontrolled on monotherapy. A 52-week, open-label extension to a double-blind study evaluated metformin-glibenclamide combination tablets (Glucovance) in 477 patients with hyperglycaemia despite sulphonylurea therapy. Reductions in HbA1C were maintained, with a mean reduction of -1.7% after 52 weeks, compared with the baseline value for the double-blind trial. Eighty-five patients receiving 4 x 500 mg/2.5 mg tablets daily displayed a marked improvement in HbA1c following up-titration to a regimen of 2 x 500 mg/2.5 mg + 3 x 500 mg/5 mg tablets. Lipid profiles improved significantly. The combination tablets were well tolerated: 11.1% of patients reported hypoglycaemic symptoms (all either mild or moderate severity). No patient withdrew or required pharmacologic intervention for hypoglycaemia. Metformin-glibenclamide combination tablets are an effective and well-tolerated therapeutic option for intensifying oral anti-diabetic therapy.
