Sitagliptin phosphate is the world's first approved oral dipeptidyl peptidase-4 (DPP-4) inhibitor, which increases insulin secretion and inhibits glucagon secretion by increasing incretin (GLP-1, GIP) levels. Sitagliptin phosphate slows gastric emptying and lowers blood glucose levels. It can also be used in conjunction with diet and exercise to improve blood glucose control in patients with type 2 diabetes1. Clinical studies have confirmed that sitagliptin phosphate tablets only need to be taken orally once a day to control blood glucose and delay the progression of diabetes effectively. In addition, sitagliptin phosphate has a low incidence of hypoglycemia. It is listed in authoritative clinical guidelines in various countries by virtue of its excellent safety and efficacy¹.

Therefore, sitagliptin phosphate tablets have a broad market prospect².
