First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study tested different combinations of diabetes drugs (glimepiride, empagliflozin, or sitagliptin) taken with metformin in 172 adults newly diagnosed with type 2 diabetes. Participants were split into four groups and took their assigned pills once daily for 90 days. Researchers measured blood sugar control (HbA1c), weight, cholesterol, and side effects to see which combination worked best and was safest.
