In recent years, new antidiabetic drug classes, such as glucagon-like peptide 1 (GLP-1) receptor agonists (RAs), sodium-glucose co-transporter-2 (SGLT-2) inhibitors, and dipeptidyl peptidase-4 (DPP-4) inhibitors, with low risk of hypoglycaemia and weight gain, have become available and are now widely used as add-on therapies after metformin [3, 4, 8]. Here, DPP4 is linked to Hypoglycemia.
