A trial of disodium cromoglycate in perennial rhinitis

In this investigation, a double-blind, cross-over trial of sodium cromoglycate in 23 patients with perennial rhinitis was carried out. An improvement in symptoms was found in actively-treated patients, and a greater preference was expressed for active treatment. There was no relationship between response to sodium cromoglycate and the results of allergological investigation. It is conclcuded that therapeutic trial of sodium cromoglycate is worth considering in patients with perennial rhinitis, irrespective of the results of RAST and intracutaneous skin tests.
