Canagliflozin is an inhibitor of sodium-glucose-co-transporter 2 (SGLT2), which is expressed in the proximal renal tubules and is responsible for the majority of the reabsorption of filtered glucose from the tubular lumen. Patients with diabetes have been shown to have elevated renal glucose reabsorption which can contribute to elevated blood glucose concentrations. Canagliflozin increases urinary glucose excretion and directly lowers plasma glucose independent of insulin.
