Summary Nineteen patients with perennial rhinitis were studied in a double blind crossover trial of 8 weeks duration using a 2% solution of sodium cromoglycate and placebo. Nasal smears, blood counts and serum IgE levels were carried out to determine whether any changes occurred with either the active or placebo formulations. Clinically, thirteen patients were greatly improved with the active solution, four showed no change and two became worse. Eosinophils in the nasal secretions were generally reduced during the administration of active solution but remained unchanged with the placebo.
