Abstract


Background: Nasal congestion is the main symptom of common cold. Symptomatic treatment with nasal decongestant seems to be the only treatment option. We managed a study to assess the efficacy of Narlisim, a developed nasal spray, on nasal congestions in common cold. Materials and methods: In this study, sixty adult patients with common cold were included. Thirty patients were treated with Narlisim nasal spray, and 30 patients with isotonic nasal spray. The primary outcome was the assessment of the speed of relief of nasal congestion; the secondary outcome was the assessment of nasal congestion and nasal secretion symptoms by a 0–100% rating Visual analog score (VAS) scale on 5 items at baseline and after 5, 10, 15, 20, 25 and 30 minutes from treatment. Results: VAS score progressively reduced for all investigated symptoms in both groups; a statistically significant higher mean reduction at each time point was recorded in the study group compared to controls (p<0.001). Conclusions: Our results suggest that Narlisim may be a promising medical device to control nasal congestion and rhinitis in common cold thanks to its nasal washing, hypertonic city, and low pH and osmo protection properties.
