| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Improvement of nasal congestion and runny nose, after 48 hours of treatment | Improvement is defined as a reduction of at least one point on the rating scale, in both nasal symptoms, after 48 hours of treatment. Participants were evaluated (self-assessment) for pain intensity by using a 4-point rating scale: 0=none, 1=mild, 2=moderate, and 3=severe. | 48 hours after single dose of double-blind treatment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall score of nasal and extranasal symptoms (nasal congestion, runny nose, sneezing, watery eyes and itching) |  | After 2 and 5 (± 1) days of treatment. | 
| Clinical score of upper airway compromise |  | After 2 and 5 (± 1) days of treatment | 
| Proportion of subjects who used at least once the rescue medication |  | Within 2 days and the period of 5 (± 1) days of treatment | 
| Safety descriptive about occurence of adverse events, evaluation of results of general physical examination. | Collection of safety data throughout the whole study period | Will be evaluated during the 5(± 1) days of treatment |
