Promising cardiovascular and blood pressure effects of the SGLT2 inhibitors: a new class of antidiabetic drugs

摘要

Patients with type 2 diabetes mellitus (T2DM) exhibit an increased risk of cardiovascular (CV) events. Treatment of these patients with traditional as well as newer glucose-lowering drugs has not demonstrated superiority in CV outcomes compared to placebo, despite effective control of diabetes. However, the recently FDA-approved sodium-glucose cotransporter 2 (SGLT2) inhibitors for the treatment of T2DM have demonstrated promising CV-protecting and blood pressure-lowering effects in addition to their effectiveness in glucose lowering, making them a novel class of drugs for the treatment of T2DM. So far, there are three SGLT2 inhibitors approved by the FDA and EMA for the treatment of T2DM: canagliflozin, dapagliflozin and empagliflozin. They exert their anti-hyperglycemic effect through inhibition of SGLT2 in the kidney and significantly reduce glucose reabsorption from the proximal renal tubule. By blocking glucose reabsorption, they lead to loss of calories, weight, abdominal and total body fat, blood pressure and CV complications. One CV outcomes randomized trial and several short-term studies have shown reductions in CV events and blood pressure in patients with T2DM. It is the hope that large ongoing long-term outcome studies will provide further much-needed information, when they are completed.
