What is the pathophysiology of angioedema?
Pathogenesis. Angioedema is caused by a rapid increase in permeability of submucosal or subcutaneous capillaries and post-capillary venules with localized plasma extravasation. Most causes of angioedema are dependent upon the release of either histamine or bradykinin; other vasoactive substances may be contributory.
What antibiotics can cause angioedema?
