Conditions

Rhinitis Sicca

Brief summary

A chronic irritation of the nasal mucosa can be painful and unpleasant for the individual. Dry nasal mucosa with scabs is a common problem but not everyone seeks care. The causes can be several such as staying for long periods in dry and dusty air, hot rooms or hot environments, tobacco smoke, side effects of drugs and mechanical irritation (nasal congestion). The nasal spray contains salic acid (neuraminic acid). This substance is found naturally in humans in the nasal mucosa which keeps it moist. Salic acid is also found, for example, in breast milk and is also found in food production. Previous studies have shown that treatment with salic acid is gentle, relieves symptoms and has a soothing and moisturising effect. The purpose of the study is to evaluate whether the symptoms of dry nose can be improved with treatment with Viiral®Nasal spray and have a soothing and moisturising effect. The treatment also aims to prevent colds caused by viruses. As a control product in the study, a nasal spray with isotonic saline solution will be used. In this study, a total of 78 women and men who have been diagnosed with dry nose / rhinitis sicca will be included in the study. After the participants have given their consent to participate in the study, treatment with the study product or control product will begin. The treatment is started by the study participants themselves at home. Two thirds will be treated with the study product and one third will be treated with a control product. Clinic visits will be performed at three occasions after the screening/baseline visit, at day 14, day 28 and on day 56.

Design outcomes

Primary

MeasureTime frameDescription
Rhinitis Sicca Symptom Score (RSSS)Up to 8 weeks.RSSS score constitutes of the sum of ten (10) individual symptoms. Each symptom assessed on 5-point scale (0 = none, 1 = mild, 2 = moderated, 3 = strong, 4 = very strong). 1. Sensation of dry nose 2. Impairment of nasal breathing/nasal obstruction 3. Crusting 4. Itching/ sneezing attacks 5. Pain in the nose 6. Nasal discharge anterior/runny nose 7. Thick nasal discharge 8. Desire to clear one's throat /dry throat 9. Impairment of smell 10. Impairment of sleep

Secondary

MeasureTime frameDescription
Nasal spray sensory scale (NSSS)Up to 8 weeks.Tolerability examination, sensory perception of the spray. Parameters to be answered using visual analog scale (VAS 0 = worst grading - 100 = best grading) 1. Did product have any taste? 2. Did product run out of nose? (amount) 3. Did product run down throat? (amount) 4. Did you feel discomfort when nozzle was inserted to your nose? 5. Did product induce the urgency to sneeze?
Short Form 12 (SF-12)Up to 8 weeks.SF-12 is a health-related quality of life questionnaire consisting of twelve questions that measure functional health and well-being form the subject's point of view.
Endoscopy score of the nasal cavity (ES)Up to 8 weeks.Changes of the nasal mucosa using a 3-point scale (0 = no, 1 = mild, 2 = severe). 1. Classification of crusting 2. Dryness of mucosa 3. Redness and oedema of nasal mucosa 4. Atrophy
Episodes of common cold/sick daysUp to 8 weeks.The total number of common cold episodes and episodes days.
