Evaluation of Tranexamic Acid for Angiotensin-converting Enzyme Inhibitor-induced Angioedema in the Emergency Department

Angiotensin-converting enzyme inhibitor ACEi induced angioedema ACEi-AE is defined as physical swelling of the deep skin layers or mucous membranes due to increased vascular permeability and leakage of fluid into the interstitial space caused while taking an ACEi

Angiotensin-converting enzyme inhibitor ACEi induced angioedema ACEi-AE most commonly affects the lips, mouth, face, upper airway, and less commonly the gastrointestinal tract. This condition may lead to life-threatening airway compromise which would require emergent intubation. Currently, strong evidence is lacking to help guide management of ACEi-AE in the emergency department (ED).

Inclusion Criteria:

•Patients must be ≥ 18 years old, be diagnosed with suspected ACEi-AE (with ACEi use). ACEi use is defined as patient-reported use or evidence indicating use listed in the chart.

Exclusion Criteria:

•Patients will be excluded if they have an allergy to TXA or any components of the formulation, present with an urticaria, have a personal or family history of hereditary angioedema, or received TXA administration in another department besides the ED.
