The study will test whether the nasal spray containing sodium sulfide nonahydrate and Saccharomyces cerevisiae extract can help reduce symptoms like nasal congestion, runny nose, and thick mucus.

The purpose of this research is to evaluate how well Actisoufre nasal spray works compared to placebo when used three times daily in each nostril for seven days. The study involves both adults and children over 6 years old who have developed sudden symptoms of nose and throat inflammation within the previous 48 hours.

During the study, participants will use either Actisoufre nasal spray or placebo. They will need to report their symptoms, including how well they sleep and their overall quality of life. The researchers will track any changes in symptoms, particularly focusing on improvements in nasal congestion, runny nose, and other related symptoms over the course of treatment.
