Abstract

In a double-blind, crossover study to determine the efficacy of cromolyn sodium in chronic perennial allergic rhinitis five of 12 patients with significant sneezing problems and four of 12 patients with significant rhinorrhea showed major improvement after a four-week course of the drug. Nasal eosinophils disappeared in five of six patients after a course of cromolyn sodium.
