Asthma, caused by
analgesics, a relatively frequent phenomenon in
bronchial asthma conditioned by
infection, often remains unrecognized and is then sometimes a danger of high degree for these patients. Pathogenetically, the
asthma caused by
analgesics perhaps does not underlie an immunological mechanism, but an induced by
analgesics prostaglandin-E-synthesis inhibition. For this speak the results of skin tests, of the LTT with
analgesics and of
IgE concentration measurements. Concomitant phenomena of the
asthma caused by
analgesics are: initial rhinirrhoe, alcohol intolerance, polyposis nasi and NNH affections. Among the evoking
noxae the
pyrazolones (regard:
pyrazolone containing
asthma mixed preparations!) are of greatest importance. Since already the smallest doses of
analgesics may evoke considerable asthmatic reactions the indication to the exposition test should be made cautiously. In an anamnestic suspicion on
asthma caused by
analgesics a strict avoidance of
analgesics,
antirheumatic drugs and
antipyretic drugs is necessary. Salicyl
amide does not cause in vitro a
prostaglandin synthesis inhibition. Still further clinical examinations are necessary, whether it amy generally be recommended as a possible alternative of
analgesics in
asthma caused by
analgesics.
