RT Journal Article SR Electronic T1 An update on the ‘gliptins’ JF Drug and Therapeutics Bulletin JO Drug Ther Bull FD BMJ Publishing Group Ltd SP 138 OP 141 DO 10.1136/dtb.2016.12.0442 VO 54 IS 12 YR 2016 UL http://dtb.bmj.com/content/54/12/138.abstract AB Progressive impairment of insulin secretion in people with type 2 diabetes leads to blood glucose concentrations worsening over time, often resulting in escalation of blood glucose lowering therapy.1 In 2015/2016, more money was spent on dipeptidyl peptidase-4 (DPP-4) inhibitors (‘gliptins’) than on any other class of antidiabetic drug except for insulins.2 In 2008, we reviewed sitagliptin and vildagliptin.3 Here, we briefly review three other DPP-4 inhibitors, saxagliptin (Onglyza—AstraZeneca), linagliptin (Trajenta—Boehringer Ingelheim) and ▼alogliptin (Vipidia—Takeda), and consider data from recent cardiovascular outcomes studies.
