(HealthDay News) — For patients with type 2 diabetes mellitus (T2DM), inadequately controlled with alpha-glucosidase inhibitors (AGIs), the addition of a dipeptidyl peptidase-4 (DPP4) inhibitor (DPP4i) is associated with a greater reduction in hemoglobin A1c (HbA1c), according to a review published online in the Journal of Diabetes Investigation.
Se Hee Min, MD, from the Seoul National University College of Medicine in South Korea, and colleagues conducted a literature review to examine the efficacy and safety of the addition of a DPP4i to patients with T2DM inadequately controlled with an AGI. Data were included from five studies with 845 patients randomized to DPP4i/AGI and 832 randomized to placebo plus AGI (PCB/AGI).
The researchers found that DPP4i/AGI correlated with a greater reduction in HbA1c than PCB/AGI (weighted mean difference, −1.2%), fasting plasma glucose, and two-hour postprandial plasma glucose levels; no increase was seen in body weight. DPP4i/AGI and PCB/AGI had similar risks of hypoglycemia and gastrointestinal adverse events.
“Addition of a DPP4 inhibitor to patients with T2DM inadequately controlled with an AGI achieved better glycemic control without further increasing the risk of weight gain and hypoglycemia,” the authors write.
