EVALUATION OF THE EFFECTIVENESS AND SAFETY OF DOSPRAY® NAZAL SPRAY IN THE SYMPTOMATIC TREATMENT OF PERSISTENT ALLERGIC RHINITIS: A POST-REGISTRATION OBSERVATION STUDY

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).

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.
