Recruiting
Conditions
Allergic Rhinitis
Interventions
Other: non-interventional study
Registration Number
NCT05896241
Lead Sponsor
LeKos LLP
Brief 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).

Detailed 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.
