Combination therapy with half-dose rosiglitazone and metformin significantly reduces the incidence of type 2 diabetes in patients with impaired glucose tolerance compared to placebo.

If you have impaired glucose tolerance, combining half-dose rosiglitazone (2mg) and metformin (500mg) twice daily significantly reduces your risk of developing type 2 diabetes (66% relative risk reduction) compared to placebo. This regimen is effective and appears safe with few side effects.

Significantly fewer patients in the treatment group (n = 14 [14%]) than in the placebo group (n = 41 [39%]) developed incident diabetes (P < 0.0001). The relative risk reduction was 66%, with a 95% confidence interval (CI) of 41 to 80.
