Usually taken once a day glucose-lowering drugs include DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors), SGLT-2 inhibitors (sodium-glucose cotransporter protein 2 inhibitors), and so on. 1.DPP-4 inhibitors. Generally include selegiline, liragliptin and saxagliptin. In patients with type 2 diabetes, they may improve glycemic control by increasing the level of active enteric insulinotropic hormone. 2. SGLT-2 inhibitors. Generally include empagliflozin, dagliflozin and canagliflozin. They can inhibit the reabsorption of glucose in the kidney and lower the renal glucose threshold, thus promoting the excretion of urinary glucose and lowering blood glucose. It is recommended that patients with high blood glucose should consult the endocrinology department of regular hospitals for treatment under the guidance of doctors.
