Intranasal corticosteroids have been shown to decrease ocular symptoms associated with allergic rhinitis as well as nasal symptoms. The primary objective of this retrospective analysis was to evaluate the efficacy of fluticasone propionate (FP) aqueous nasal spray in the treatment of ocular symptoms in patients with seasonal allergic rhinitis (SAR). We pooled efficacy data from seven multicenter, randomized, double-blind, placebo-controlled studies of similar design. Each study evaluated the efficacy of intranasal FP, 200 micrograms, given once daily in the treatment of nasal and ocular symptoms associated with SAR. At baseline and after 7 and 14 days of treatment, clinicians rated the severity of four individual ocular symptoms (itching, tearing, redness, and puffiness) via visual analog scales of 0-100, where 0 = no symptoms and 100 = worst symptoms. The four ratings were added to form the total ocular symptom score (TOSS). Patients rated the overall severity of their ocular symptoms (all symptoms evaluated with a single score) daily on diary cards in a similar fashion. The primary outcome was the mean change from baseline in the clinician-rated TOSS. A between-group difference of 25 points in the mean change from baseline TOSS by day 14 was considered clinically relevant. The FP group had greater mean changes from baseline in the TOSS and in all four individual symptom scores compared with placebo at days 7 and 14. At day 7, mean decreases from baseline in the TOSS were 76.0 points for the FP group and 50.9 points for the placebo group (p < 0.001), a difference between groups of 25.1. At day 14, mean decreases from baseline in the TOSS were 91.8 points for the FP group and 60.2 points for the placebo group (p < 0.001), a difference between groups of 31.6. Consistent with the clinician-rated data, patient-rated data showed a significantly greater reduction in the overall ocular symptom score for the FP group compared with placebo for both weeks 1 and 2 (p < 0.001). Intranasal FP provides safe and effective relief of ocular symptoms associated with SAR. Patients with allergic rhinitis who also have ocular symptoms as a component of their disease may benefit from intranasal FP monotherapy without the addition of topical ophthalmologic agents or oral antihistamines. Such an approach may have advantages regarding compliance and cost-effectiveness of treatment.
OBJECTIVE:To evaluate whether 1 year of continuous treatment with intranasal fluticasone propionate would lead to atrophy in the nasal mucosa compared with an active control, oral terfenadine.DESIGN:Prospective, randomized, multicenter, open-label, parallel-group study.SETTING:Two tertiary care academic institutions.PATIENTS:Seventy-five subjects older than 18 years with perennial allergic rhinitis.INTERVENTIONS:Patients received either fluticasone propionate aqueous nasal spray, 200 microg once daily, or terfenadine, 60 mg twice daily, for 1 year. Nasal biopsy specimens were obtained before and after 1 year of treatment and were evaluated for evidence of atrophy.MAIN OUTCOME MEASURES:Epithelial and collagen layer thickness of the nasal mucosa as assessed by light microscopy and the presence and degree of edema, and regularity of collagen fibrils as assessed by electron microscopy. Analyses were performed without knowledge of subject identity or treatment assignment.RESULTS:Neither fluticasone nor terfenadine treatment led to atrophy in the nasal mucosa by clinical or histologic observation. No significant changes from baseline were observed for any assessment of atrophy. In contrast to what would have been expected if atrophy were to occur, mean epithelial layer thickness in the fluticasone group significantly increased compared with terfenadine treatment (P = .03).CONCLUSIONS:Treatment with intranasal fluticasone for 1 year increases the thickness of the nasal epithelium as compared with a year's treatment with terfenadine and does not lead to atrophy in the nasal mucosa. The increased thickness in the fluticasone treatment may represent repair from epithelial damage caused by chronic allergic inflammation.
BACKGROUND:The effectiveness of fluticasone propionate (FP) aqueous nasal spray in the treatment of rhinitis has been demonstrated in multiple controlled clinical studies. The onset of therapeutic effect of FP in these clinical trials appears to occur within 12 hours after administration of the initial dose. OBJECTIVE:This article presents an analysis from previous clinical trials that examined the efficacy of intranasal FP in patients with rhinitis to ascertain whether the time to onset of the therapeutic effect of this medication could be determined. METHODS:Completed randomized, double-blind, placebo-controlled studies with FP were evaluated to determine whether onset of effect could be evaluated based on the study designs. A study was deemed acceptable for evaluation of onset of effect if at least one evaluation of the intensity of nasal symptoms was completed within 12 hours after the initial dose of study medication and daily evaluations were made thereafter. Adult patients were included in the onset analysis if they received an initial FP dose of 200 microg. Pediatric patients who received an initial FP dose of 100 microg were also included. Onset of effect was evaluated by 1) examining the timepoints at which statistically significant differences were observed between FP and placebo in mean change from baseline for total nasal symptom score (TNSS); and by 2) using a binary probability model of success/failure to determine statistically significant differences from placebo. RESULTS:Twenty-two studies met the criteria to evaluate onset of therapeutic effect; 3,605 patients with rhinitis received FP and 2,271 patients received placebo. This database represents the largest compilation of data ever assembled to determine the onset of therapeutic effect of a corticosteroid nasal spray. Two studies used a "park design" to examine onset of effect; statistically significant differences in TNSS favoring FP were achieved at hours 2 to 4 and at hour 12, respectively. Using a binary probability model of success/failure for analysis of TNSS in the remaining 20 studies not specifically designed to evaluate onset of effect, numerically greater improvements in TNSS for FP compared with placebo were found in 19 of the 20 studies within 12 hours of the administration of the first dose (P < .001). Pairwise comparisons showed statistically significant improvement for TNSS within 12 hours postdose in five of the studies for FP compared with placebo and in none for placebo compared with FP. CONCLUSIONS:Onset of therapeutic effect occurs within 12 hours, and as early as 2 to 4 hours in some patients, after administration of the first dose of FP aqueous nasal spray.
BACKGROUND:Intranasal corticosteroids and oral antihistamines are both effective in the treatment of seasonal allergic rhinitis, although the therapeutic value of administering the two types of agents concurrently has rarely been evaluated. This study was designed to compared the efficacy, safety, and impact on quality of life of fluticasone propionate aqueous nasal spray (FP ANS), loratadine, FP ANS plus loratadine, and placebo (an aqueous nasal spray plus tablet) in the treatment of seasonal allergic rhinitis during the mountain cedar allergy season in south central Texas.METHODS:Six hundred patients with seasonal allergic rhinitis were treated for 2 weeks with either FP ANS 200 microgram once daily, loratadine 10 mg once daily, the FP ANS and loratadine regimens combined, or placebo in a multicenter, randomized, double-blind, double-dummy, parallel-group study.RESULTS:Clinician- and patient-rated total and individual nasal symptom scores after 7 and 14 days of therapy and overall evaluations were significantly lower (P < .001) in the FP ANS and FP ANS plus loratadine groups compared with the loratadine only and placebo groups. Loratadine was not statistically different from placebo in clinician and patient symptom score ratings nor in overall clinician and patient evaluations. FP ANS plus loratadine and FP ANS monotherapy were comparable in efficacy in almost all evaluations; for some patient-rated symptoms the combination was found superior. Mean score changes in the Rhinoconjunctivitis Quality of Life Questionnaire from baseline to day 14 showed significantly greater improvement (P < .001) in quality of life in the FP ANS group than in the group of patients receiving loratadine only or placebo and no significant benefit was demonstrated in the FP ANS plus loratadine group over the FP ANS monotherapy group. No serious or unusual drug-related adverse events were reported. Combining loratadine with FP ANS did not alter the adverse events profile or frequency.
