Outcome Measures
Primary Outcomes (1)
The total nasal symptom score (TNSS)
Primary objective: Demonstrate the superiority of the experimental drug (FDC desloratadine 0.5 mg/mL/prednisolone 4 mg/mL from Eurofarma Laboratórios SA) compared to desloratadine 0.5 mg/mL in alleviating symptoms of moderate/severe allergic rhinitis in children through the absolute variation of the total nasal symptom score (TNSS) five (05) days after the treatment start. The TNSS is determined by the sum of the intensity scores attributed to the symptoms of nasal obstruction, runny nose, nasal itching and sneezing in the last 24 hours. Each symptom is assessed using a 4-point categorical scale (0=absent symptom, 1=mild symptom, 2=moderate symptom, 3=intense symptom).

- Total nasal symptom score (TNSS ) ≥ 8 points.
- Symptom intensity score "nasal obstruction" ≥ 2 points.
- Signing of the Informed Consent Form (ICF) by the legal guardian and the Informed Assent Form (IAF) before performing any study procedure.
You may not qualify if:
- Being using or having an indication for antibiotic therapy upon selection for the study.

- Presence of any serious or uncontrolled diseases, at the investigator's discretion.
- Presence of pregnancy or lactation.
- At the discretion of the investigator, female participants who are already of childbearing age must confirm the use of contraception or expressly declare that they are not at risk of pregnancy because they do not engage in sexual practices or do so in a non-reproductive manner.
- Participation in a clinical research protocol in the last 6 months, unless, according to the investigator's criteria, their participation in the study could imply a direct benefit for the participant.
- Presence of any condition that, at the investigator's discretion, renders the patient unfit to participate in the study.
