Impact of time to treatment intensification on glycemic goal attainment among patients with type 2 diabetes failing metformin monotherapy.

Background: Patients with type 2 diabetes on metformin monotherapy frequently require treatment intensification with another anti-hyperglycemic medication over time. Previous studies have indicated that a high proportion of patients with diabetes have a significant delay in the initiation of oral add-on therapy after metformin alone fails to achieve targeted glycemic control. In this study, we evaluated the impact of the timing of treatment intensification with oral add-on drug on glycemic goal attainment among diabetic patients failing metformin monotherapy.
