Final answer:
DPP-4 inhibitors are oral antidiabetic drugs used in the treatment of diabetes. They work by blocking the action of the DPP-4 enzyme, which increases the levels of incretin hormones that stimulate insulin secretion and suppress glucagon release. Examples include sitagliptin, saxagliptin, and linagliptin.
Step-by-step explanation:
DPP-4 (dipeptidyl peptidase 4) inhibitor is a type of oral antidiabetic drug used in the treatment of diabetes. It works by blocking the action of the DPP-4 enzyme, which breaks down incretin hormones. By inhibiting this enzyme, DPP-4 inhibitors increase the levels of incretin hormones, such as GLP-1, which stimulate insulin secretion and suppress glucagon release. Some examples of DPP-4 inhibitors include sitagliptin, saxagliptin, and linagliptin.
