Seawater formulations
Saline nasal sprays may improve mucosal function through several physiological effects
The nasal sprays of the Otrivin Natural range may be used as an adjunct treatment.2
Both hypertonic and isotonic formulations:1,3
- Remove inflammatory mediators
- Improve mucociliary clearance
- Moisturise the area
Hypertonic saline solutions decongest the nasal mucosa through the action of osmosis,4 while isotonic saline solutions aid decongestion through mechanical cleansing.1
A clinical study demonstrates that the administration of natural saline nasal solutions improves symptoms of nasal obstruction7
In a randomised double-blind trial, both hypertonic and isotonic saline nasal solutions were found to improve mucociliary clearance after administration, improving symptoms of nasal stuffiness and obstruction. In this study, isotonic saline was also found to improve nasal airway patency while the hypertonic solution had no effect.7
Seawater and natural saline nasal sprays are indicated for those who prefer a natural alternative for the relief of nasal dryness and irritation2
