Demonstration of a Decongestant Effect of “Coldamaris Akut” Compared to Saline Nasal Spray in Participants Suffering from Seasonal Allergic Rhinitis

Abstract

Purpose Carrageenan-containing nasal sprays are known to alleviate symptoms of common cold and allergic symptoms by building a barrier against airborne intruders. The objective of this study was to develop a hyperosmolar nasal spray with barrier-forming properties and to demonstrate its decongestant effect in the context of allergic rhinitis.
