Farxiga is a medication belonging to a class of drugs known as sodium-glucose cotransporter 2 (SGLT2) inhibitors. It contains the active ingredient dapagliflozin and is primarily used for the treatment of type 2 diabetes mellitus. Farxiga works by inhibiting the SGLT2 protein in the kidneys, which normally reabsorbs glucose from the urine back into the bloodstream. By blocking this protein, Farxiga prevents glucose reabsorption and increases its excretion through urine. As a result, blood sugar levels are reduced, leading to improved glycemic control. Additionally, Farxiga promotes mild diuretic effects, which can help lower blood pressure and reduce fluid retention in some patients. This mechanism helps lower blood sugar levels and improves glycemic control in individuals with diabetes.

Farxiga is primarily prescribed to individuals with type 2 diabetes. It is used as an adjunct to diet and exercise to help improve glycemic control. By inhibiting glucose reabsorption in the kidneys, Farxiga helps lower blood sugar levels and reduces the risk of diabetes-related complications.

In recent years, Farxiga has also been approved to treat heart failure with reduced ejection fraction (HFrEF). This condition occurs when the heart fails to pump blood effectively, leading to fluid retention and other symptoms. Farxiga has shown significant benefits in reducing the risk of cardiovascular death or hospitalization due to heart failure.

Farxiga is commonly prescribed to individuals diagnosed with type 2 diabetes. This medication is intended for adult patients, including those who may have additional cardiovascular risks. It may be suitable for individuals who have not achieved adequate glycemic control through lifestyle modifications, such as diet and exercise, alone. It is important to note that Farxiga is not approved for the treatment of type 1 diabetes or diabetic ketoacidosis.
