How does bradykinin cause cough
WebBradykinin-mediated angioedema is a rare disease, due to vasodilation and increased vascular permeability resulting from bradykinin. This kind of angioedema affects abdominal and/or upper airways. It differs clinically from histamine-mediated angioedema by the absence of urticaria or skin rash. How does bradykinin cause dry cough? Bradykinin is also thought to be the cause of the dry cough in some patients on widely prescribed angiotensin-converting enzyme (ACE) inhibitor drugs. It is thought that bradykinin is converted to inactive metabolites by ACE, therefore inhibition of this enzyme leads to increased levels of bradykinin; increased bradykinin sensitizes somatosensory fibers and thus causes hyperalgesia. Bradykinin may mediate this via pro-inflammatory peptides (e.g. substance P, neuropeptide Y) a…
