| E.5 End points | 
| E.5.1 | Primary end point(s) | 
To compare the efficiency of the treatment between fixed combination of xylometazoline and dexpanthenol (Septanazal®), nasal spray, and xylometazoline, nasal spray, on nasal congestion in the two groups of patients:
 • Group 1 - patients after nasal surgery or nasal cavities surgery (CRSwNP and CRSsNP patients)
 • Group 2 - patients diagnosed with acute rhinitis
 
 | 
 
 
 | 
| E.5.1.1 | Timepoint(s) of evaluation of this end point | 
| After 7 days of treatment | 
 
 
 | 
| E.5.2 | Secondary end point(s) | 
To compare the efficiency of the treatment between fixed combination of xylometazoline and dexpanthenol (Septanazal®), nasal spray, and xylometazoline, nasal spray, in the Group 1 and Group 2 in the following parameters:
 • swelling of the nasal mucosa
 • dryness of the nasal mucosa
 • burning feeling in the nose
 • crust formation
 • bleeding from nasal mucosa
 • redness of the nasal mucosa and skin at nasal entrance
 • sneezing
 • nasal exudate

 To compare the treatment duration and occurrence of rebound effect between fixed combination of xylometazoline and dexpanthenol (Septanazal®), nasal spray, and xylometazoline, nasal spray, in the Group 1 and Group 2.
 
 To compare the onset of action between fixed combination of xylometazoline and dexpanthenol (Septanazal®), nasal spray, and xylometazoline, nasal spray, in the Group 1 and Group 2.
