A comparison of azelastine nasal spray and cetirizine tablets in the treatment of allergic rhinitis.

A total of 40 patients with perennial allergic rhinitis were treated with either azelastine nasal spray 0.14 mg/nostril twice daily (0.56 mg/day) or cetirizine tablets 10 mg once daily. Treatment was for a period of eight weeks. The rhinitis symptoms were evaluated according to a four-point scale (0 = absent, 3 = severe). The Total Rhinitis Symptom Score (TRSS) was derived from the sum of the individual symptom scores. Symptoms were assessed at baseline prior to treatment and at weeks 2, 4 and 8. Compared baseline, TRSS for both the azelastine and cetirizine groups were less at each assessment during treatment, a slight non-significant advantage was seen in the azelastine group. At the end of the study, physicians rated global efficacy as being "good" or "excellent" in 73.7% of azelastine patients and 55.5% of cetirizine patients. Both treatments were well tolerated and no serious adverse events were reported, however, two cetirizine patients withdrew from the study because of somnolence. In conclusion, azelastine has been shown to be at least as effective as cetirizine in the relief of the symptoms of perennial allergic rhinitis.
