Clinical Trial Summary

The combined use of dexamethasone and oxymetazoline has a vasoconstrictive, anti-inflammatory and anti-allergic effect when applied topically in diseases of the upper respiratory tract. The main goal of this research is Evaluation of the effectiveness of Dospray® nasal spray in the treatment of persistent allergic rhinitis. The study will involve 126 patients diagnosed with allergic rhinitis: 1. Patients taking Dospray = 63 2. Patients on other alternative treatment = 63 Duration of Patient Participation - 7-10 days (duration of treatment for an individual patient).

Description:

Primary task: Overall assessment of the effectiveness of Dospray® nasal spray in the treatment of persistent allergic rhinitis. Secondary Tasks: - Symptomatic evaluation of the effectiveness of Dospray® nasal spray in the treatment of persistent allergic rhinitis; - Evaluation of the effect of Dospray® nasal spray on conjunctive symptoms in the treatment of persistent allergic rhinitis; - Evaluation of the effect of Dospray® nasal spray on the severity and frequency of nasal symptoms in the treatment of persistent allergic rhinitis; - Assessment of the quality of life before and after the use of Dospray® nasal spray in the treatment of persistent allergic rhinitis; - Safety assessment of the use of nasal spray Dospray®. Study Endpoints: 1. Dynamics of scores on the scale of the reflective Total nasal symptoms score (TNSS) [Time: 7 days] 2. Dynamics of scores on the scale of the individual reflective Total nasal symptoms score (iTNSS) [Time: 7 days] 3. Dynamics of scores on the scale of the reflective Total ocular symptom score (rTOSS) 4. Changes in Visual Analogue Scale (VAS) scores for the severity and frequency of nasal symptoms [Time: 7 days]. 5. Dynamics of scores on the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) scores [Time: 7 days] 6. Adverse reactions [Time: 7 days] Number of yellow cards.
