Comparison of the effects of fluticasone propionate aqueous nasal spray and loratadine on daytime alertness and performance in children with seasonal allergic rhinitis.

BACKGROUND: Concern has been directed at the relative sedating properties of lipophilic and lipophobic antihistamines, but few studies have sought to determine the comparative benefit of seasonal allergic rhinitis (SAR) treatments in controlling symptoms and consequently improving alertness.
OBJECTIVE: To compare the relative contributions of fluticasone propionate aqueous nasal spray and loratadine in enhancing daytime performance in 8- to 17-year-old children.
METHODS: All participants had a documented history of SAR, positive response to a skin prick (wheal 3-mm greater than negative control or equal to the positive control) for seasonal aeroallergens, and clinically identifiable symptoms at the time of randomization. Following confirmation during baseline of current SAR symptoms, participants were randomized to 1 of the 2 treatments and returned 2 weeks later for evaluation of symptom control, quality of life, attention, reaction time, and memory.
RESULTS: Children in the fluticasone propionate aqueous nasal spray group but not the loratadine group demonstrated improvement in nasal symptoms, nasal quality of life score, and composite verbal memory. No differences were identified on any scores from the Conners Continuous Performance Test.
CONCLUSIONS: Treatments that most effectively control SAR symptoms are also likely to provide the greatest benefit to children whose daytime functioning, including their capacity to learn at school, is compromised by their illness.
