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.
