Type 2 Diabetes Warning Signs

What is dapagliflozin, and how does it work (mechanism of action)?

Dapagliflozin (Farxiga) is an oral medication used to improve glycemia (blood glucose) control in patients with type 2 diabetes. Dapagliflozin is a sodium-glucose cotransporter (SGLT2) inhibitor. It is similar to canagliflozin (Invokana) and empagliflozin (Jardiance). SGLT2 is found in the kidney tubules and is responsible for reabsorbing the majority of glucose filtered out of the blood by the kidneys. By inhibiting SGLT2 dapagliflozin reduces the reabsorption of filtered glucose and consequently increases excretion of glucose in the urine. Dapagliflozin is not recommended for use in patients with moderate to severe kidney disease. Dapagliflozin was approved by the US FDA in January 2014.
