Abstract
The onset of increased airways obstruction after analgesic ingestion by asthmatics with analgesic idiosyncrasy suggests type 1 allergic response. The effect of sodium cromoglycate (DSCG) on this response was assessed in 19 patients with this syndrome, DSCG prevented asthmatic attacks in only 3 patients, all non-atopic, suggesting that analgesic idiosyncrasy is not an allergic disorder. The effectiveness of DSCG in preventing asthmatic attacks in some patients with analgesic idiosyncrasy suggests that a trial of this preparation should be undertaken before commencing continuous corticosteroid therapy.
