SGLT2 Inhibitors


About SGLT2

Sodium-glucose cotransporter-2 (SGLT2) inhibitors are a class of oral (taken by mouth) prescription medicines that are FDA-approved for use with diet and exercise to lower blood sugar in adults with type 2 diabetes. SGLT2 inhibitors, which are also called "flozins", are a class of drugs that lower your blood sugar levels by preventing your kidneys from reabsorbing sugar that is created by your body and the extra sugar leaves through in your urine.


Originally, SGLT2 inhibitors were developed as oral antidiabetic (blood sugar lowering) drugs. Later clinical trial data showed significant improvement in kidney function in people with diabetes who already had diabetic nephropathy.

Medicines in the SGLT2 inhibitor class include Invokana® (canagliflozin), Farxiga® (dapagliflozin), Jardiance® (empagliflozin), and Steglatro® (ertugliflozin).

Dosing & Administration

Available SGLT2 inhibitors work in relatively the same way. Currently, all SGLT2 inhibitors are taken orally (by mouth and some of them are also available in extended release formulas.


SGLT2 inhibitors are effective at slowing the progression of kidney disease, reducing heart failure, and lowering the risk of kidney failure and death in people with kidney disease and type 2 diabetes. SGLT2 inhibitors also protect the kidneys of people with CKD who do not have diabetes.

Studies have shown that some medications in this drug class may also reduce the risk for heart disease in people with a history of heart disease.3 They have also been shown to reduce the need for hospitalization for heart failure.
