RESUMO

Two double-blind, randomized, placebo-controlled, parallel group safety and efficacy studies included evaluation of the hypothalamic-pituitary-adrenal (HPA)-axis effects of concurrent treatment with intranasal and orally inhaled fluticasone propionate (FP). In the first study, patients with asthma who were > or =12 years of age were assigned randomly to receive twice-daily doses (either 88 or 220 microg) of orally inhaled FP delivered from a metered-dose inhaler (MDI). In the second study, patients were assigned randomly to receive either orally inhaled FP 250 microg or orally inhaled FP 250 microg/salmeterol 50 microg delivered via the Diskus device. In both studies, patients with rhinitis were allowed to continue the use of intranasal FP at their usual dosing. Treatment periods were 26 weeks and 12 weeks for the MDI and Diskus studies, respectively. HPA-axis effects were assessed using response to short cosyntropin stimulation testing. The number and percentage of patients with an abnormal cortisol response, defined as a morning plasma cortisol of <5 microg/dL, a poststimulation peak of <18 microg/dL, or a poststimulation rise of <7 microg/dL, were summarized in two subgroups: patients who used intranasal FP and those who did not. The concurrent administration of intranasal FP and orally inhaled FP via an MDI or Diskus or via Diskus with salmeterol was not associated with HPA-axis effects compared with orally inhaled FP alone. The results of these two studies suggest that concurrent use of intranasal FP with orally inhaled FP administered via MDI or Diskus for treatment of comorbid rhinitis and asthma does not increase the risk of HPA-axis abnormalities.

RESUMO

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.

RESUMO

BACKGROUND: Few published clinical trials document the efficacy of intranasal corticosteroids used as needed for treatment of seasonal allergic rhinitis. OBJECTIVE: To evaluate the efficacy and safety of 4 weeks' treatment with fluticasone propionate aqueous nasal spray 200 microg used as needed (FP200PRN) in patients with seasonal allergic rhinitis. METHODS: A randomized, double-blind, placebo-controlled study in 241 patients (> or = 12 years of age) with a positive skin test result to a relevant fall allergen and who were symptomatic at randomization. The primary endpoint was the mean change from baseline in total nasal symptom score (TNSS; the sum of nasal congestion, rhinorrhea, sneezing, and nasal itching, each rated on a 4-point scale from 0 = none to 3 = severe). RESULTS: The mean percentage of days that patients used the study medications in the FP200PRN and placebo groups was 61.8% (SD = 30.4%) and 70.1% (SD = 28.3%), respectively. Patients treated with FP200PRN had a significantly greater reduction from baseline in TNSS compared with those treated with vehicle placebo (mean +/- SE = -2.02 +/- 0.18 vs -1.06 +/- 0.22, P < 0.001), representing a 91% greater improvement with FP200PRN than vehicle placebo. The FP200PRN group also had a significantly greater (P < 0.001) mean reduction in individual nasal symptoms of rhinorrhea, sneezing, nasal itching, and nasal congestion compared with placebo. FP200PRN was well tolerated, with an incidence of adverse events comparable to vehicle placebo. CONCLUSIONS: FP200PRN in patients 12 years and older is effective for treatment of nasal symptoms associated with seasonal allergic rhinitis. It has a lower incidence of adverse events than typically associated with regular once-daily use.

RESUMO

OBJECTIVE: Fluticasone propionate aqueous nasal spray (FP) at the highest recommended doses does not affect hypothalamic-pituitary-adrenal (HPA) axis function in adults or older children, but its potential effects in children younger than 4 years have not been previously studied. This randomized, double-blind, placebo-controlled study evaluated the effects of FP on HPA axis function measured by 12-hour urinary-free cortisol levels in children 2 to 3 years of age. METHODS: Patients ages 2 to 3 years with symptoms of allergic rhinitis were administered FP 200 microg/day (FP200 QD) or vehicle placebo for 6 weeks. RESULTS: The FP200 QD group (n = 33) was equivalent to the placebo group (n = 32) in mean change from baseline in the primary safety measure of 12-hour creatinine-corrected urinary-free cortisol concentration (geometric mean difference [standard error; SE] for placebo-FP200 QD = 0.96 [1.20]; 95% confidence interval 0.66, 1.39) at the end of the treatment period. The adjusted geometric mean change from baseline value was 0.98 for FP200 QD (SE = 1.14) and 0.94 for placebo (SE = 1.15); a value of 1.0 reflects no change from baseline. Cough and fever were the most common adverse events reported in either group. CONCLUSIONS: FP200 QD was equivalent to placebo with respect to effects on HPA axis function measured by 12-hour urinary-free cortisol in 2- and 3-year-old patients. FP200 QD was well-tolerated in these very young children with allergic rhinitis.

RESUMO

Although allergic rhinitis is commonly associated most with symptoms of nasal congestion, rhinorrhea, sneezing, and itching, the symptom of sinus pain and pressure often prompts the patient to seek medical attention. The effect of fluticasone propionate on this symptom has not been studied. The purpose of this study was to compare the efficacy and safety of fluticasone propionate aqueous nasal spray to placebo vehicle in the treatment of patients with sinus pain and pressure arising from allergic rhinitis. A multicenter, double-blind, parallel-group trial was conducted in 206 symptomatic patients > or = 12 years with seasonal or perennial allergic rhinitis. Patients were treated for 14 days with either fluticasone propionate aqueous nasal spray, 200 mcg once daily, or placebo vehicle. Patients attended clinic visits and kept diary cards rating sinus pain and pressure (measured as one symptom) and nasal congestion symptoms during the study. Treatment with fluticasone propionate provided significantly greater relief of symptoms of sinus pain and pressure compared with placebo over the entire 14-day treatment period. Nasal congestion scores also were significantly reduced compared with placebo at each time point. Treatments were well tolerated, and the incidence of adverse events attributable to study treatments was similar between groups. Our data indicate that symptoms of sinus pain and pressure and nasal congestion can be significantly reduced in patients with allergic rhinitis when treated with fluticasone propionate aqueous nasal spray, 200 mcg once daily.

RESUMO

BACKGROUND: Although response to intranasal corticosteroid therapy has been reported in patients with nonallergic rhinitis with eosinophilic syndrome (NARES), efficacy specifically in non-NARES patients has not been fully characterized. OBJECTIVE: To evaluate the efficacy of intranasal fluticasone propionate (FP) in the treatment of patients with perennial nonallergic rhinitis, with and without nasal eosinophilia. METHODS: Data from 983 patients in three randomized, double-blind, placebo-controlled PNAR trials were integrated. Patients received a total daily dose of FP 200 microg (n = 332), FP 400 microg (n = 325), or placebo (n = 326) for 28 days. Patients were > or =12 years of age with perennial rhinitis and negative skin tests to all allergens relevant to the geographic region. Nasal eosinophils were evaluated using a five-point scale. Patients were classified as non-NARES with a point score of 0 (n = 674; 69%); patients with a point score between I and 4 were classified as NARES (n = 309; 31%). Efficacy of FP was evaluated by the mean change in total nasal symptom score (TNSS), a sum of patient ratings of nasal obstruction, postnasal drip, and rhinorrhea. RESULTS: Patients with either NARES or non-NARES had similar statistically significant improvement with FP 200 microg or 400 microg compared with placebo; thus, the total group comprising both varieties of rhinitis responded to FP. In the total population, both FP treatment groups showed significantly greater improvement in TNSS compared with placebo during each week of treatment (P < or = 0.002), with mean changes in TNSS for day 22 to day 28 ranging from -84 and -85 in the FP 200 microg and FP 400 microg groups, respectively, to -64 in the placebo group. The three study treatment groups had similar proportions of non-NARES (68 to 69%) and NARES (31 to 32%) patients at baseline. In the non-NARES subgroup, mean changes in TNSS for each treatment group were similar to changes seen in the total population. In the NARES subgroup, mean changes in TNSS for the FP 200 microg and placebo groups were similar to changes seen in the total population; mean change in TNSS for the FP 400 microg group was somewhat greater than changes seen in the total population. CONCLUSIONS: Intranasal FP is an effective treatment for perennial nonallergic rhinitis with or without nasal eosinophilia (NARES or non-NARES).
