The effect of disodium cromoglycate in perennial allergic rhinitis. A controlled clinical study

The clinical effect of disodium cromoglycate was compared with placebo in patients with perennial allergic rhinitis. The results of a double-blind cross-over trial in 17 patients suggest that insufflation with 10 mg disodium cromoglycate four times a day has no better effect than placebo. No significant differences between the side effect of disodium cromoglycate and placebo were noted.
