Abstract:
The ARIA (Allergic Rhinitis and its Impact on Asthma) guidelines proposed a classification for allergic rhinitis based on the duration of symptoms (intermittent or persistent) rather than on the time of allergen exposure (seasonal or perennial). There had been no placebo-controlled, randomized, clinical trial of desloratadine (DL) in patients with persistent allergic rhinitis to date.To assess the efficacy and safety of DL in patients with persistent allergic rhinitis based on the ARIA classification.Patients 12 years of age and older with persistent allergic rhinitis were assessed over 85 days of treatment with DL 5 mg once daily (n = 360) or placebo (n = 356). The primary endpoint was the AM/PM reflective total 5-symptom score (T5SS) averaged over days 1-29. Secondary endpoints included AM/PM instantaneous T5SS and individual symptoms, therapeutic response, symptom severity assessed by a visual analogue scale and quality of life.The mean reduction in AM/PM reflective T5SS was significantly greater with DL than placebo over days 1-29 (-3.76 vs. -2.87, p < 0.001) and on each individual day (p < 0.05). The mean AM instantaneous T5SS was significantly reduced with DL compared with placebo as early as day 2 (-1.90 vs. -1.46; p < 0.001). The therapeutic response and improvement in quality of life were significantly greater with DL than placebo (p < 0.001 for each). The frequency of treatment-related adverse events was low and similar between DL (10.0%) and placebo (8.4%).This study showed DL to be effective and safe in the treatment of persistent allergic rhinitis.
