title: Nasal symptoms in pseudoallergic reactions.
abstract: In a retrospective investigation 469 pseudoallergic reactions (analgesics asthma reactions) that emerged in 197 patients with analgesics intolerance have been analysed. Besides mostly severe asthma-attacks 26.5% of the reactions were sneeze-attacks and in 37.5% nasal secretion was found. 86% of the reactions emerged within a maximum of 45 minutes after oral application of the analgesic. About a third of the analgesics-asthma reactions occurs together with reactions of the nose mucous membrane. So the connection of analgesics-asthma and chronic hyperplastical changes of the mucous membrane of the upper respiratory tract is also reflected in the course of the pseudoallergic intolerance reaction.
