Two naturalistic studies compared desloratadine and fexofenadine for the treatment of nasal conges- tion in patients with SAR. Berger et al69 conducted a multicenter, randomized, double-blind comparison of desloratadine 5 mg/d, fexofenadine 180 mg/d, and pla- cebo given for 15 days in 722 subjects (66% female, 34% male; mean age, 35 years [range, 12–84 years]) with a ≥2-year history of moderate SAR. By day 15, both active agents were associated with significant re- ductions compared with placebo in morning/evening reflective individual symptom scores (both, P < 0.05), including nasal congestion (both, P = 0.013). Instan- taneous individual symptom scores were also im- proved with both active treatments compared with placebo (P < 0.05), although the improvement in nasal congestion did not reach statistical significance with either drug.
