Treatment with azelastine hydrochloride and fluticasone propionate in a single delivery device of young children and adolescents with allergic rhinitis.

Background: Allergic rhinitis (AR) is the most common chronic noncommunicable disease worldwide that affects any age during the human life span but raises particular concerns among the parents and caregivers of the children who are affected. H1-receptor antagonists and corticosteroids provide the most effective way of bringing the condition under control. Intranasal application of these medications has the advantage of a faster onset of action and avoids systemic unwanted adverse effects. The only combination treatment, which comprises azelastine hydrochloride and fluticasone propionate, so far in a single advanced delivery system has proven its efficacy and safety in clinical trials of adult patients with AR. Objective: To critically review and identify gaps in the existing data for children in all different strata of pediatric ages. Methods: We searched the specialized medical literature for publications on the efficacy and safety of the combined formulation of azelastine and fluticasone in a single delivery device in adolescents (ages < 18 years) and children (ages < 12 years). Results: Altogether, 12 peer-reviewed articles have been published about trials that also involved subjects in different strata of the pediatric ages, seven of the articles pooled adolescents and adults. Three articles presented the results of studies in children ages 4 to 11 years specifically designed to overcome the difficulties that children experience in expressing themselves verbally. Conclusion: All the trials with the novel combination product that involved young children and adolescents documented its efficacy, effectiveness, and safety. However, the numbers of the youngest children (ages 4 and 5 years) were low, which suggested that further data about safety and efficacy in this age group are needed.
