A 55 year old male was recently started on a new medication for diabetes management. He presents to the Emergency Department with angioedema. What is the likely culprit?
Dipeptidyl Peptidase-4 Inhibitor. Dipeptidyl Peptidase-4 Inhibitors affect the degradation of the vasoactive kinins bradykinin and substance P, both of which can cause angioedema.
