Pharmacological therapy using antidiabetic drugs can delay the onset of type 2 diabetes in individuals with impaired glucose tolerance (IGT) (1–3). These drugs lower blood glucose, but each drug class impacts glucose dysregulation by a different mechanism (4). It is unclear whether simply lowering mean blood glucose can reduce the risk of type 2 diabetes or whether it is the drug effect on particular targets of glucose dysregulation or other unknown drug effects that allow for the decreased incidence of type 2 diabetes in IGT.
Metformin decreases the incidence of type 2 diabetes in IGT (3). But whether metformin treatment earlier in the disease process might further delay progression …
