Omarigliptin
Omarigliptin is a potent, long-acting oral antidiabetic drug of the DPP-4 inhibitor class used for once-weekly treatment of type 2 diabetes and currently under development by Merck & [Co.] It inhibits DPP-4 to increase incretin levels, which inhibit glucagon release, which in turn increases insulin secretion, decreases gastric emptying and decreases blood glucose levels.
