SPRA: Efficacy of ADW S-100 Ionized Water Nasal Spray in Decreasing Symptoms of Allergic Rhinitis
Study Details
Study Description
Brief Summary
A nasal spray based on Advanced Water S-100 ionized water would clean the nasal cavities, reduce the viscosity of mucus and facilitate its elimination and decongestion of the nose and the prevention of the bridging of the allergen to the epithelial cells of the cavity nose at the origin of the onset of symptoms.
Indeed, a water-based nasal spray ionized Advanced Water S-100 would modify the electrostatic environment of all the interactions ensuring this bridging. Negative ions (OH-) contained in water ionized Advanced Water S-100 competes with negative ions from acids negatively charged amino acids and also neutralize basic amino acids positively charged. The destabilization of all the links governing the process of epitope/IgE association would prevent the bridging of the FcɛRI receptors of the mast cell and thus the cascade of cellular responses that cause symptoms.
The purpose of this study is to assess whether the use of ionized water nasal spray ADW S-100 allows to sufficiently reduce the intensity of the symptoms of allergic rhinitis and thus improve the quality of life of people with allergies.

Outcome Measures
Primary Outcome Measures
- percentage of patients with a change of at least 23 mm VAS (Visual Analogue Scale) at D4 [14 days]
minimum 0 and maximum 100 (higher scores mean a worse outcome)
Secondary Outcome Measures
- percentage of change on D4 and D14 compared to D0 of symptoms (nasal obstruction, sneezing, rhinorrhea, sore throat) [14 days]
- percentage of change on D4 and D14 compared to D0 of eye symptoms (itching, tearing, redness) [14 days]
- VAS from D0 to D14 [14 days]
minimum 0 and maximum 100 (higher scores mean a worse outcome)
- Allergic rhinitis control test on D0 and D14 [14 days]
- percentage of patients without symptoms at D4 and D14 [14 days]
- percentage of patients who used antihistamines [14 days]
- Proportion of premature discontinuations of the study or discontinuations of the product under study [14 days]
- Proportion of attendees presenting events adverse events (AE), serious adverse events (SUE), AEs related to the product of the study, AEs of interest particular: respiratory infections [14 days]
- Proportion of participants - satisfied or very satisfied - judging the use easy or very easy [14 days]
