CKD is when your kidneys become damaged over a long period of time. When you he CKD, your kidneys can no longer filter waste out of the blood like they once did. If you he CKD, one treatment goal is to slow its progression or stop it from worsening.
The Food and Drug Administration (FDA) first approved Farxiga to treat type 2 diabetes because of its ability to lower blood sugar. In 2021, it also approved the drug to treat CKD. The drug might help your kidneys even if you don’t he diabetes.
How does it work?
Jier Zayas Photography/Getty ImagesFarxiga, the branded form of the generic drug dapagliflozin, can help the kidneys by reducing hyperglycemia (high blood sugar). It may also work by reducing pressure between some blood vessels called glomeruli, which filter blood in the kidneys. Farxiga may benefit someone with kidney disease whether or not they he diabetes.
High blood sugar over time can lead to CKD. According to the Centers for Disease Control and Prevention (CDC), about 1 in 3 people with diabetes he CKD. CKD can happen whether you he type 1 or type 2 diabetes.
Farxiga reduces the amount of sugar reabsorbed by the kidneys. It increases sugar output in the urine and improves blood glucose management. In this way, it can lower blood glucose levels.
Healthcare professionals originally prescribed Farxiga and other drugs in the same class — called sodium-glucose cotransporter 2 (SGLT2) inhibitors — because they lower blood glucose.
But researchers he found that the drugs might also protect against kidney and heart disease, even if a person doesn’t he diabetes. A 2020 study indicated that Farxiga resulted in a lower risk of decline in people with CKD, regardless of whether they had diabetes.
Farxiga first came on the market in 2014 to help people with type 2 diabetes manage blood sugar.
Note that according to expert guidelines, people who he had a kidney transplant shouldn’t take Farxiga as there isn’t enough research into its effects in this case.
