SGLT2 inhibitor / biguanide combinations are used to treat Type 2 diabetes and reduce the risk of cardiovascular events in certain adults with Type 2 diabetes. These medications work by combining two actions: SGLT2 inhibitors which help your kidneys remove excess glucose (sugar) through urine and biguanides which reduce glucose production in your liver and improve your body's sensitivity to your natural insulin. These combinations are available as oral tablets. Examples include dapagliflozin / metformin (Xigduo XR), empagliflozin / metformin (Synjardy, Synjardy XR), and canagliflozin / metformin (Invokamet, Invokamet XR).
