Oral Sodium Cromoglycate in Chronic Urticaria

Abstract
Fifteen patients were included in a double-blind cross-over trial to investigate the efficacy of oral sodium cromoglycate in the treatment of chronic urticaria. Only patients with positive oral provocation tests were entered into the study. The challenging agents were food additives or antirheumatic agents. Treatments were taken for 4 wk and the dose of sodium cromoglycate was 200 mg 4 times daily. No significant differences were found between active and placebo treatment periods for diary card symptom scores. Six patients preferred active treatment, 2 preferred placebo and 7 had no preference. The clinician showed no preference for either treatment.
