Xigduo XR (dapagliflozin/metformin) is a combination blood glucose lowering medication that is manufactured by AstraZeneca. It is FDA-approved to be used in combination with diet and exercise to lower blood sugar levels in adults with type 2 diabetes mellitus (T2DM).
Xigduo XR can be used to reduce the risk of complications from heart failure in adults with type 2 diabetes and cardiovascular disease.
In adult patients with chronic kidney dysfunction, Xigduo is used to reduce the risk of end-stage renal disease, hospitalization, and death from heart failure. Xigduo XR is not indicated to treat type 1 diabetes mellitus (T1DM) and can increase the risk of diabetic ketoacidosis in these patients.
How does Xigduo XR work?
Xigduo XR is the combination of 2 classes of medications that are used to improve glycemic control in patients with T2DM. It contains a biguanide medication (metformin) and a sodium-glucose co-transporter 2 inhibitor (dapagliflozin).
Biguanides such as metformin work by reducing the amount of sugar your liver produces. They also decrease the amount of sugar your body absorbs and improves how your body responds to insulin.
SGLT-2 inhibitors such as dapagliflozin work in your kidneys to increase the amount of glucose that is removed by your urine, which lowers your blood sugar levels.
