Summary

This study tested whether an ectoine nasal spray works better than a cromoglycic acid spray for easing allergic rhinitis symptoms like a stuffy nose, runny nose, and sneezing. Fifty adults with proven allergies used one of the two sprays for 14 days. Doctors and patients rated how well the treatment worked at day 7 and day 14.
