The purpose of this study is to evaluate the non-inferiority clinical efficacy of two different drug associations in the treatment of Moderate - Severe Persistent Allergic Rhinitis.

Condition Intervention Phase
Allergic Rhinitis Drug: Dexchlorpheniramine + Betamethasone Drug: Desloratadine + Prednisolone Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Double-blind, Randomized, Multicenter Parallel-group Study on Efficacy of Desloratadine and Prednisolone Association Compared to Dexchlorpheniramine and Betamethasone Association in Children (2-12 Years) With Moderate - Severe Persistent Allergic Rhinitis

Further study details as provided by EMS:

Primary Outcome Measures:
  • Efficacy of treatment in persistent allergic rhinitis based on nasal symptoms score [ Time Frame: 7 days ]
    The mean variability of nasal symptoms score observed between visit 1 and visit 2 will be used as the primary endpoint of clinical efficacy.

Secondary Outcome Measures:
  • Safety will be evaluated by the adverse events occurrences [ Time Frame: 7 days ]
    Adverse events will be collected and followed in order to evaluate safety and tolerability

Enrollment: 210
Study Start Date: November 2013
Study Completion Date: October 2014
Primary Completion Date: October 2014 (Final data collection date for primary outcome measure)
