Long-Term Safety and Efficacy of Triamcinolone Acetonide Aqueous Nasal Spray for the Treatment of Perennial Allergic Rhinitis
This 12-month, multicenter, open-label study to assess the long-term safety and efficacy of triamcinolone acetonide (TAA) aqueous nasal spray for perennial allergic rhinitis (PAR) symptom relief was a continuation of a 4-week, double-blind study. Patients who received TAA Aqueous (220 g/day) during the 4-week, double-blind study continued with the same treatment for the open label study; those randomized to placebo during the 4-week, double-blind study received TAA Aqueous (220 g/day) for the open-label study. Dose reduction to 110 g/day was allowed if it was felt that symptom relief would be maintained. Safety was assessed by daily diary entries and clinical laboratory results. Long-term efficacy was assessed by visual analog scale (VAS). Of the 172 patients who began the open-label study, 94.2 percent completed 3 months of treatment, 83.6 percent completed 6 months, and 62 percent completed 12 months. PAR symptom relief improved progressively throughout the study. Adverse events were generally mild or moderate and consistent with long-term use and winter symptoms. The most common adverse events were pharyngitis (32 percent of patients), rhinitis (28.5 percent), headache (22.1 percent), and epistaxis (18 percent). Adverse events related to the local effects of the study medication were similar to those observed in long-term studies with TAA aerosol. The aqueous nasal spray formulation of triamcinolone acetonide was well tolerated and continued to relieve nasal symptoms with long-term use in adolescent and adult patients with PAR.
