Bradykinin angioedema mechanism. Plasma and tissue factors such as bradykinin and certain components in the contact system or the fibrinolytic system are also found to play an important role in certain forms of angioedema. It is also a pain mediator. Bradykinin is released by various cell types in response to numerous different stimuli. Bradykinin mediated angioedema ae is a clinical syndrome characterised by episodes of subcutaneous or mucosal oedema extremities throat respiratory and digestive tracts referred to as attacks. Angioedema is a nonitchy pale swelling of subcutaneous or submucosal tissue that tends to recur chronically and can become life threatening if the swelling occurs in the upper airwa. One issue is that anything injected into hereditary angioedema skin will produce bradykinin because of the trauma.

Angioedema due to ace inhibitors acei aag may be life threatening and will probably become more common with expanding use of ace inhibitors. This is not responsive to treatments for allergic angioedema eg epinephrine steroid antihistamines. Bradykinin also plays a crucial role in inflammation. Bradykinin is released from mast cells during asthma attacks from gut walls as a gastrointestinal vasodilator from damaged tissues as a pain signal and may be a neurotransmitter. Using the new test in six angioedema patients investigators confirmed the medicines mechanism of action. The companys leading therapy kvd900 was developed to inhibit plasma kallikrein the protein that helps kininogen cleave onto bradykinin.

Dampening or inhibiting bradykinin has been shown to relieve hae symptoms. Acei aag is due to excessive bradykinin. Various mechanisms that interfere with bradykinin production or degradation can lead to angioedema.
