1.Should be based upon known pathogenic abnormalities, and NOT simply on the reduction in HbA 1c 2.Will require multiple drugs in combination to correct multiple pathophysiologic defects 3.Must be started early in the natural history of T2DM, if progressive -cell dysfunction is to be prevented Treatment of Type 2 Diabetes
