Asthma and seasonal allergic rhinitis (SAR) are recognized as manifestations of a single airway disease. Desloratadine has demonstrated efficacy in treating SAR symptoms, including nasal obstruction.


Safety and efficacy of desloratadine and montelukast each were assessed in a double-blind, placebo-controlled trial of patients with SAR and symptoms of asthma, who were assigned randomly to once-daily treatment with desloratadine 5 mg, montelukast 10 mg, or placebo for 4 weeks. Change from baseline of AM/PM reflective total asthma symptom severity scores (TASS), FEV(1), individual asthma symptom scores, and beta(2)-agonist usage were assessed.


Desloratadine and montelukast each were associated with statistically significant reductions from baseline in the mean TASS averaged over the 4-week period (p < or =0.022 vs. placebo). Individual asthma symptom scores also improved significantly for both therapies (p < or = 0.05). Patients treated with desloratadine or montelukast demonstrated improvement from baseline in FEV(1) versus placebo; significant improvement was seen in a subset of patients with baseline FEV(1) <80% of predicted normal (both p < 0.05). Both active therapies significantly reduced beta(2)-agonist use (both p < 0.01). Improvements for both therapies were comparable for all efficacy parameters; they were tolerated well with adverse event profiles similar to placebo.


Asthma symptoms and beta(2)-agonist were improved significantly in patients with concomitant SAR and asthma treated with desloratadine 5 mg as well as montelukast 10 mg once daily. Both therapies significantly improved FEV(1) in a subset of patients with FEV(1) <80% of predicted normal at entry. Improvements in asthma symptoms were comparable for both active treatment groups.
