SGLT2 Inhibitors

SGLT2 inhibitors are a newer drug class with a less certain long-term safety profile. SGLT2 is a low-affinity, high capacity glucose transporter located in the proximal tubule in the kidneys. It is responsible for 90% of glucose reabsorption. Inhibition of SGLT2 leads to the decrease in blood glucose due to the increase in renal glucose excretion. The mechanism of action of these drugs gives further glucose control by allowing increased insulin sensitivity and uptake of glucose in the muscle cells, decreased gluconeogenesis and improved first phase insulin release from the beta cells.

 

empagliflozin was shown in one trial to reduce cardiovascular risk in people with CVD and type 2 diabetes. Adverse effects for SGLT2 inhibitors included a higher rate of genital infections, DKA, acute kidney injury, fracture, and/or amputation. inhibits sodium-glucose cotransporter 2 (SGLT2), reducing glucose reabsorption and increasing urinary glucose excretion. SGLT2 inhibitors control blood sugar levels by excreating of glucose by the kidneys. SGLT2 inhibitors are not used in the treatment of Type 1 DM.
