Fluticasone propionate 50 micrograms BID versus 100 micrograms BID in the treatment of children with persistent asthma. Fluticasone Propionate Study Group.

The aim of this multicenter, double-masked study was to compare the efficacy and safety of two different doses of inhaled fluticasone propionate dry powder--50 micrograms and 100 micrograms--administered BID via a multidose powder inhaler with those of placebo in the treatment of children with persistent asthma. After a 2-week run-in period, 263 patients were randomized to treatment with twice-daily placebo (n = 92), fluticasone 50 micrograms (n = 85), or fluticasone 100 micrograms (n = 86) for 12 weeks. One hundred sixty-six (63%) patients were male, and 224 (85%) were white, with a mean age of 8 years. Two hundred twenty-one (84%) patients were atopic, and 167 (63%) had been asthmatic for 1 to 5 years. Baseline mean morning peak expiratory flow (PEF) values were 207 L/min, 199 L/min, and 194 L/min, and baseline percentages of predicted normal values were 86%, 80%, and 81% for the groups receiving placebo, fluticasone 50 micrograms, and fluticasone 100 micrograms, respectively. At the end of the first week of treatment, patients in both fluticasone groups had significantly greater improvements in morning PEF than did those receiving placebo. Patients experienced mean increases of 4 L/min, 22 L/min, and 26 L/min with placebo, fluticasone 50 micrograms, and fluticasone 100 micrograms, respectively. At the end point (the last evaluable visit), patients in both fluticasone groups continued to have significantly greater improvements in morning PEF than did patients receiving placebo. Patients experienced mean increases of 17 L/min, 50 L/min, and 57 L/min with placebo, fluticasone 50 micrograms, and fluticasone 100 micrograms, respectively. Changes in the percentage of predicted values by end point were 8%, 20%, and 26% with placebo, fluticasone 50 micrograms, and fluticasone 100 micrograms, respectively. The probability of remaining in the study, according to predefined withdrawal criteria, indicated a significant treatment difference in favor of fluticasone. Withdrawal criteria were met by 63%, 42%, and 29% of patients receiving placebo, fluticasone 50 micrograms, and fluticasone 100 micrograms, respectively. This study clearly demonstrates the superiority of fluticasone 50 and 100 micrograms BID over placebo in the treatment of persistent asthma in children.

Fluticasone propionate aerosol for the treatment of adults with mild to moderate asthma. The Fluticasone Propionate Asthma Study Group.

BACKGROUND: Recent emphasis on the control of airway inflammation in asthma highlights the need for safe and effective antiinflammatory agents. Fluticasone propionate is one of the most potent antiinflammatory corticosteroids developed to date. OBJECTIVE: This study assessed the safety and efficacy of fluticasone propionate aerosol in the treatment of mild to moderate asthma. METHODS: Fluticasone propionate aerosol (25, 100, or 500 micrograms twice daily) or placebo was given for as long as 8 weeks to adults with mild to moderate asthma in a randomized, double-blind, parallel-group study. Patients were removed from the study if they showed predefined signs of worsening asthma. RESULTS: Sixty-three percent of placebo-treated patients and 23%, 13%, and 4% of patients treated with fluticasone propionate 25, 100, and 500 micrograms twice daily, respectively, were removed from the study. Mean forced expiratory volume in 1 second, forced vital capacity, and forced expiratory flow at midexpiratory phase at weekly visits throughout the study demonstrated that fluticasone propionate was more efficacious than placebo in maintaining asthma control. Measurements of peak expiratory flow and symptom scores significantly improved and nighttime awakenings and albuterol use to treat symptoms significantly declined in fluticasone propionate-treated groups relative to the placebo-treated group. Differences among fluticasone propionate groups for these variables were not statistically significant. Incidence and severity of adverse events were similar across groups. Fluticasone propionate did not affect morning or stimulated plasma cortisol concentrations, although slight, transient reductions in urinary free cortisol and urinary 17-hydroxy steroids occurred in the group receiving 500 micrograms fluticasone propionate twice daily. CONCLUSION: These data indicate that fluticasone propionate provides safe and effective treatment for mild to moderate asthma.

Treatment of seasonal allergic rhinitis with once-daily intranasal fluticasone propionate therapy in children. Fluticasone Propionate Collaborative Pediatric Working Group.

PURPOSE: To evaluate the efficacy and tolerability of intranasally administered fluticasone propionate, 200 micrograms or 100 micrograms (half the adult dosage) when administered once daily for 4 weeks to children with seasonal allergic rhinitis. DESIGN AND SETTING: Double-blind, randomized, placebo-controlled, parallel-group clinical study in 10 pediatric outpatient centers. SUBJECTS: Children (n = 249), 4 to 11 years of age, with moderate to severe symptoms of seasonal allergic rhinitis, positive skin test reaction to a local autumn allergen, and a history of seasonal allergic rhinitis. MEASUREMENTS: Clinician- and patient-rated nasal symptom scores (obstruction, rhinorrhea, sneezing, itching), clinician-rated assessment of overall response to treatment, patient-rated nasal obstruction on awakening, and use of rescue medication. Clinicians questioned patients (or parents) regarding symptoms and adverse events. Morning plasma cortisol concentrations and 24-hour urinary excretion of cortisol and 17-ketogenic steroids were evaluated. RESULTS: Intranasal fluticasone propionate, 200 micrograms or 100 micrograms once daily, was significantly more effective than placebo in the treatment of seasonal allergic rhinitis in children. Clinician- and patient-rated symptom scores indicated greater improvement in nasal symptoms, including nasal obstruction on awakening, among patients receiving intranasal fluticasone propionate. Overall response to treatment was also significantly greater in the active treatment groups. The two fluticasone propionate groups were not statistically different. Mean morning plasma cortisol concentrations and 24-hour urinary excretion of free cortisol and 17-ketogenic steroids were similar across all groups both before and after treatment. CONCLUSIONS: Intranasal fluticasone propionate, 100 micrograms (half the adult dose) or 200 micrograms given once daily for 4 weeks is effective and well tolerated in children 4 to 11 years of age with seasonal allergic rhinitis.

Growth in asthmatic children treated with fluticasone propionate. Fluticasone Propionate Asthma Study Group.

OBJECTIVE: To determine whether inhaled fluticasone propionate has long-term effects on growth in children with persistent asthma. STUDY DESIGN: In a double-blind, randomized, parallel-group, multicenter study, 325 prepubescent children with persistent asthma and normal growth rates were treated with placebo or inhaled fluticasone propionate powder 50 microg or 100 microg administered twice daily by a breath-actuated device for 1 year. Growth was evaluated monthly, whereas other safety variables and pulmonary function were evaluated periodically. RESULTS: The prepubescent patients showed no statistically significant differences in mean height, mean growth velocity, or mean skeletal age between any of the treatment groups at any time. Over a period of 1 year, mean height (+/- SE) increased 6.15 +/- 0.17 cm in the placebo group, 5.94 +/- 0.16 cm in the fluticasone propionate 50 microg group, and 5.73 +/- 0.13 cm in the fluticasone propionate 100 microg group (p = 0.308, overall). CONCLUSIONS: Prepubescent children treated with fluticasone propionate 50 microg and 100 microg administered twice daily for 1 year grew at rates similar to placebo-treated control subjects and at rates equal to expected growth velocity for age.

Fluticasone propionate aerosol: efficacy in patients with mild to moderate asthma. Fluticasone Propionate Asthma Study Group.

BACKGROUND: This double-blind, randomized, parallel-group, placebo-controlled study investigated the efficacy and tolerability of fluticasone propionate aerosol (25, 50, or 100 mg bid for 12 weeks) administered as primary maintenance therapy to patients whose mild to moderate asthma was inadequately controlled by as-needed use of an inhaled beta-agonist. RESULTS: At all clinic visits, fluticasone propionate compared with placebo was associated with significant (P<.05) improvement in pulmonary function indexed by forced expiratory volume in 1 second (FEV1) as well as fewer night awakenings and less use of rescue albuterol. Values for patient-measured morning peak expiratory flow rates (PEFR) were significantly (P<.05) higher and the use of rescue albuterol was significantly (P<.05) lower beginning 3 to 5 days after initiation of therapy in the groups treated with fluticasone propionate, compared with the placebo group. Maximal improvement in FEV1 was achieved during the second week of treatment and maintained throughout the course of therapy. Differences among the three fluticasone propionate dosing groups for these efficacy measures were not statistically significant. The incidence of adverse events was similar across groups. CONCLUSIONS: These data indicate that fluticasone propionate aerosol is an effective and well-tolerated treatment for asthma and significantly improves pulmonary function within days of initiation of treatment in patients whose asthma is inadequately controlled with as-needed beta-agonists.

High dose fluticasone propionate, 1 mg daily, versus fluticasone propionate, 2 mg daily, or budesonide, 1.6 mg daily, in patients with chronic severe asthma. International Study Group.

Airway inflammation is now regarded as fundamental in the pathogenesis of asthma and treatment with inhaled corticosteroids has proved effective. There is a need for drugs in this category with higher topical potency but fewer side-effects than those presently available. A double-blind, parallel group study was conducted in 671 patients with severe asthma (already taking between 0.8-2.0 mg of inhaled corticosteroid daily) to compare the safety and efficacy of 6 weeks of treatment with inhaled fluticasone propionate (FP), 1 mg daily, to fluticasone propionate, 2 mg daily, and budesonide (BUD), 1.6 mg daily, delivered via a metered-dose inhaler. Peak expiratory flow (PEF), asthma symptoms, and usage of rescue medication were recorded daily by the patient. At each clinic visit (-2, 0, 3 and 6 weeks) morning serum cortisol levels, bone markers and spirometry were assessed. The changes in mean morning PEF from baseline (weeks 1-6) were: FP 2 mg daily +24 l.min-1; FP 1 mg daily +21 l.min-1; BUD 1.6 mg daily +13 l.min-1. A similar rank order for the three treatments was seen for evening PEF, clinic spirometry, reduction of diurnal PEF variation, symptom scores, and requirement for rescue bronchodilators. The mean serum cortisol levels remained well within the normal range in all three groups. Analysis of the geometric mean cortisol ratio (treatment/baseline ratio after 6 weeks treatment) showed a changed rank order, the values being: FP 1 mg daily 1.04; BUD 1.6 mg daily 0.97; FP 2 mg daily 0.88.(ABSTRACT TRUNCATED AT 250 WORDS)

The addition of salmeterol to fluticasone propionate versus increasing the dose of fluticasone propionate in patients with persistent asthma. Salmeterol Study Group.

BACKGROUND: Current treatment guidelines define inhaled corticosteroids such as fluticasone propionate (FP) as the cornerstone of anti-inflammatory therapy for asthma. OBJECTIVE: The objective was to evaluate the efficacy and safety of adding salmeterol therapy to patients who remain symptomatic while receiving FP as compared with increasing the dose of FP. METHODS: In a multicenter, double-blind study conducted over 24-weeks, 437 patients aged 12 years and older and receiving FP 88 microg twice daily for 2 to 4 weeks were randomly assigned to receive either salmeterol (42 microg twice daily) or FP 220 microg twice daily. The primary efficacy endpoint was morning peak expiratory flow. Secondary measures included FEV1, symptom scores, nighttime awakenings, and supplemental albuterol use. Safety was assessed by reported adverse events and asthma exacerbations. RESULTS: The addition of salmeterol resulted in significantly greater improvements in lung function and symptom control as compared with increasing the dose of FP. Over weeks 1 to 24, morning peak expiratory flow was increased by 47 L/min from baseline with salmeterol treatment as compared with 24 L/min with FP 220 microg twice daily (P < .001) while the percent of symptom-free days increased from baseline by 26% of days as compared with 10% of days (P < .001). The adverse event profiles were similar between groups and fewer exacerbations were reported with salmeterol treatment. CONCLUSIONS: The addition of salmeterol therapy to patients who remain symptomatic while using a low dose of FP was clinically and statistically superior to increasing the dose of FP.

Evaluation of the buccal component of systemic absorption with inhaled fluticasone propionate.

BACKGROUND: Inhaled corticosteroids have dose related systemic effects determined by oral (swallowed or oropharyngeal absorption) and lung bioavailability. A study was undertaken to evaluate the significance of oropharyngeal absorption for fluticasone propionate. METHODS: Sixteen healthy volunteers of mean age 29.3 years were studied using an open randomised, placebo controlled, four way crossover design. Treatments were: (a) fluticasone metered dose inhaler (pMDI) 250 microg, 8 puffs; (b) fluticasone pMDI 250 microg, 8 puffs + mouth rinsing/gargling (water); (c) fluticasone pMDI 250 microg, 8 puffs + mouth rinsing/gargling (charcoal); and (d) placebo pMDI, 8 puffs + mouth rinsing/gargling (water). Overnight (ONUC) and early morning (EMUC) urinary cortisol/creatinine ratios and 8 am serum cortisol (SC) levels were measured. RESULTS: Significant (p<0. 05) suppression of ONUC, EMUC, and SC occurred with each active treatment compared with placebo. The mean values (95% CI for difference from placebo) were: (a) ONUC (nmol/mmol): fluticasone (2. 8, 95% CI 3.6 to 7.9), fluticasone + water (3.1, 95% CI 3.3 to 7.7), fluticasone + charcoal (2.3, 95% CI 4.1 to 8.5); placebo (8.6); (b) EMUC (nmol/mmol): fluticasone (5.6, 95% CI 8.4 to 24.5), fluticasone + water (7.6, 95% CI 6.6 to 22.4); fluticasone + charcoal (5.6, 95% CI 8.7 to 24.5); placebo (22.1). There were no significant differences between active treatments. The numbers of subjects with an overnight urinary cortisol of <20 nmol/10 hours were 0 (placebo), 11 (fluticasone), 12 (fluticasone + water), and 13 (fluticasone + charcoal). CONCLUSIONS: Oropharyngeal absorption of fluticasone does not significantly contribute to its overall systemic bioactivity as assessed by sensitive measures of adrenal suppression. In view of almost complete hepatic first pass inactivation with fluticasone, there is no rationale to employ mouth rinsing to reduce its systemic effects although it may be of value for reducing oral candidiasis.

Inhaled fluticasone propionate: a review of its therapeutic efficacy at dosages < or = 500 microg/day in adults and adolescents with mild to moderate asthma.

UNLABELLED: Fluticasone propionate is a corticosteroid with comparatively high receptor affinity and topical activity. Inhaled fluticasone propionate < or =500 microg/day provided effective corticosteroid maintenance treatment in patients with mild to moderate asthma in randomised, controlled clinical studies of 4 to 24 weeks in duration. Dosages of 50 to 250 microg twice daily produced consistent improvement in spirometric measures of lung function, reduced the frequency of as-needed beta2-agonist bronchodilator use, asthma symptom scores and night-time wakenings, and prevented asthma exacerbations compared with placebo. Fluticasone propionate < or =250 microg twice daily provided significantly greater improvements in lung function than nedocromil 4 mg 4 times daily, theophylline (5 to 15 mg/L) or zafirlukast 20 mg twice daily. Health-related quality of life improved significantly with fluticasone propionate 88 microg twice daily, but not zafirlukast 20 mg twice daily or placebo. In comparative trials in which fluticasone propionate was given at half the dosage of beclomethasone dipropionate, budesonide or flunisolide, fluticasone propionate < or =250 microg twice daily produced equivalent or greater improvement in spirometric parameters and equivalent reductions in the use of as-needed beta2-agonists than beclomethasone dipropionate, budesonide or flunisolide. Fluticasone propionate 250 microg twice daily was generally more effective than triamcinolone acetonide 200 microg 4 times daily in two 24-week trials. The combination of inhaled fluticasone propionate < or =250 plus salmeterol < or =50 microg twice daily allowed for the use of lower dosages of the inhaled corticosteroid. The incidence of adverse events in patients receiving inhaled fluticasone propionate 50 to 250 microg twice daily was similar to that in beclomethasone dipropionate 168 to 500 microg twice daily and budesonide 100 to 600 microg twice daily recipients and greater than that in recipients of triamcinolone acetonide 200 microg 4 times daily in comparative trials. The incidence of oral candidiasis was < or =8% in patients treated with fluticasone propionate < or =250 microg twice daily or other agents. There was no evidence of clinically significant hypothalamo-pituitary-adrenal (HPA) axis suppression with fluticasone propionate < or =250 microg twice daily in comparative trials. CONCLUSIONS: Inhaled fluticasone propionate < or =500 microg/day is an effective antiinflammatory therapy for mild to moderate asthma in adolescents and adults. The drug is more effective than nedocromil, theophylline or zafirlukast and is at least as effective as other inhaled corticosteroids administered at twice the fluticasone propionate dosage. The addition of inhaled salmeterol allows the use of lower maintenance dosages of fluticasone propionate. The drug is well tolerated and there is no evidence of a clinically significant effect of this dosage on HPA axis function. Hence, fluticasone propionate < or =500 microg/day is a particularly suitable agent for patients with mild to moderate asthma.

The efficacy of fluticasone propionate aqueous nasal spray for allergic rhinitis and its relationship to topical effects.

Fluticasone propionate aqueous nasal spray is an intranasal corticosteroid for the treatment of patients with allergic rhinitis. This double-masked, double-dummy, parallel-group study was conducted to confirm that the efficacy of fluticasone propionate nasal spray is attributable to topical rather than systemic effects. A total of 304 patients with documented seasonal allergic rhinitis were randomly assigned to receive fluticasone propionate nasal spray 200 micrograms once daily (n = 77), oral fluticasone propionate 5 mg once daily (n = 73), oral fluticasone propionate 10 mg once daily (n = 77), or placebo (n = 77) for 14 days. Plasma fluticasone propionate concentrations were determined at baseline and after 14 days of treatment (day 15). Nasal symptoms were recorded daily by patients and assessed weekly by clinicians. On day 15, more patients in the oral fluticasone propionate 5-mg or 10-mg groups, compared with patients in the fluticasone propionate nasal spray group or the placebo group, had detectable plasma fluticasone propionate concentrations, and mean concentrations were higher in the oral fluticasone propionate groups. Both clinician- and patient-rated total and individual nasal symptom scores for obstruction, rhinorrhea, sneezing, and itching were significantly lower in the fluticasone propionate nasal spray group compared with either of the oral fluticasone propionate groups or the placebo group. With few exceptions, oral fluticasone propionate (5 mg or 10 mg) was not significantly different from placebo on any measures of efficacy. These findings indicate that the efficacy of fluticasone propionate nasal spray (200 micrograms once daily) in the treatment of allergic rhinitis results from direct topical effects rather than from indirect effects after systemic absorption.

Comparative adrenal suppression with inhaled budesonide and fluticasone propionate in adult asthmatic patients.

BACKGROUND: A study was performed to compare the adrenal suppression caused by inhaled fluticasone propionate and budesonide on a microgram equivalent basis, each given by metered dose inhaler to asthmatic patients. METHODS: Twelve asthmatic patients of mean age 29.9 years, with a forced expiratory volume in one second (FEV1) 92.9% predicted and forced expiratory flow 25-75% (FEF25-75) 69.5% predicted, on less than or equal to 400 micrograms/day inhaled corticosteroid, were studied in a double blind placebo controlled crossover design comparing single doses of inhaled budesonide 400, 1000, 1600, 2000 micrograms and fluticasone propionate 500, 1000, 1500, 2000 micrograms. Doses were administered at 22.00 hours by metered dose inhaler with mouth rinsing and measurements were made in the laboratory 10 hours later. RESULTS: Serum cortisol levels compared with placebo (mean 325.2 nmol/l) were suppressed by fluticasone at doses of 1500 micrograms (211.6 nmol/l) and 2000 micrograms (112.3 nmol/l) and by budesonide at 2000 micrograms (243.4 nmol/l). Fluticasone propionate 2000 micrograms produced lower absolute serum cortisol levels than budesonide 2000 micrograms (95% CI for difference 42.9 to 219.2). The dose ratio (geometric mean) for the relative potency was 2.89 fold (95% CI 1.19 to 7.07). In terms of percentage suppression versus placebo, fluticasone propionate also produced greater effects (means and 95% CI for difference): budesonide 1600 micrograms (16.0) versus fluticasone propionate 1500 micrograms (40.9) (95% CI -0.6 to 50.6), budesonide 2000 micrograms (26.0) versus fluticasone 2000 micrograms (65.2) (95% CI 10.5 to 67.8). Individual serum cortisol levels at the two highest doses showed 15 of 24 patients below the normal limit of the reference range (150 nmol/l) for fluticasone and five of 24 for budesonide. Fluticasone propionate also caused greater ACTH suppression than budesonide (as % versus placebo): budesonide 1600 micrograms (12.0) versus fluticasone propionate 1500 micrograms (31.9) (95% CI 7.6 to 32.1), budesonide 2000 micrograms (13.5) versus fluticasone propionate 2000 micrograms (44.4) (95% CI 13.2 to 48.7). For overnight 10 hour urinary cortisol (nmol/10 hours) there was a difference between the lowest doses of the two drugs: budesonide 400 micrograms (37.2) versus fluticasone propionate 500 micrograms (19.9) (95% CI 6.9 to 27.8). CONCLUSIONS: Like budesonide the systemic bioactivity of fluticasone propionate is mainly due to lung vascular absorption. Fluticasone propionate exhibited at least twofold greater adrenal suppression than budesonide on a microgram equivalent basis in asthmatic patients.

Comparison of the efficacy and safety of inhaled fluticasone propionate 200 micrograms/day with inhaled beclomethasone dipropionate 400 micrograms/day in mild and moderate asthma.

This study was designed to compare the efficacy and safety of a new inhaled corticosteroid, fluticasone propionate at a total daily dose of 200 micrograms, with beclomethasone dipropionate 400 micrograms/day in childhood asthma. A total of 398 asthmatic children (aged 4-19 years) were randomised to receive either fluticasone propionate 200 micrograms daily or beclomethasone dipropionate 400 micrograms daily for six weeks inhaled via a spacer device from a metered dose inhaler. During the study the patients recorded morning and evening peak expiratory flow rate (PEFR), symptom scores, and use of beta 2 agonist rescue medication. In addition, clinic visit PEFR and forced expiratory volume in one second were measured. Safety was assessed by recording all adverse events and by performing routine biochemistry and haematology screens including plasma cortisol concentration before and after treatment. For the purposes of analysis the diary card data were grouped into three periods: week 3 (days 15-21), week 6 (days 36-42), and weeks 1-6 (days 1-42). The results showed no significant difference between treatments on most efficacy parameters. However, there were significant differences in changes from baseline in favour of fluticasone propionate for % predicted morning PEFR both at week 3 (fluticasone propionate 6.1%, beclomethasone dipropionate 3.9%) and at week 6 (fluticasone propionate 8.3%, beclomethasone dipropionate 5. 9%) and % predicted evening PEFR at week 6 (fluticasone propionate 7.3%, beclomethasone dipropionate 4.9% and over weeks 1-6 (fluticasone propionate 5.5%, beclomethasone dipropionate 3.6%. Comparison between groups showed that the group receiving fluticasone propionate had a lower % of days with symptom-free exercise at week 6 (fluticasone propionate 87%, beclomethasone dipropionate 81%) and % days without rescue medication at week 6 (fluticasone propionate 87%, beclomethasone dipropionate 80%) and over weeks 1-6 (fluticasone propionate 80%, beclomethasone dipropionate 73%). Except for a higher incidence of sore throat in the fluticasone propionate group, the two treatments did not differ with regard to safety. There was no evidence of adrenal suppression with either treatment. In conclusion, fluticasone propionate 200 microgram daily ws at least as effective and as well tolerated as beclomethasone dipropionate 400 microgram daily in childhood asthma.

Fluticasone propionate compared with theophylline for mild-to-moderate asthma.

BACKGROUND: The inhaled corticosteroid, fluticasone propionate, was compared with the oral bronchodilator theophylline in the maintenance treatment of asthma. OBJECTIVE: The objective of the present study was to compare the efficacy and safety of twice-daily inhaled fluticasone propionate, 50 micrograms, and fluticasone propionate, 100 micrograms, with that of theophylline in the maintenance treatment of mild-to-moderate asthma. METHODS: In this randomized, double-blind, placebo-controlled, parallel-group study, 353 adult and adolescent patients with asthma inadequately controlled with inhaled beta-agonist therapy alone received fluticasone propionate, 50 micrograms, or fluticasone propionate, 100 micrograms, by metered-dose inhaler; theophylline capsules; or placebo twice daily for 12 weeks. Only inhaled albuterol was permitted as needed for acute symptoms. RESULTS: Both fluticasone propionate groups had a significantly greater probability of remaining in the study (ie, meeting asthma stability criteria) than did either the theophylline or placebo group (P < or = .008); 39% and 51% in the theophylline and placebo groups, respectively, were withdrawn due to lack of treatment efficacy compared with 14% and 21% in the fluticasone propionate, 50 micrograms, and fluticasone propionate, 100 micrograms, groups. Both fluticasone propionate groups experienced significantly greater improvement in FEV1 and PEF compared with patients in the theophylline or placebo group (P < or = .004). The incidence of potentially drug-related adverse events was significantly greater in the theophylline group (25%) than in the placebo group (11%) (P = .031), while there were no differences between placebo and fluticasone propionate, 50 micrograms, (18%) or fluticasone propionate 100 micrograms, (22%). CONCLUSION: Twice daily treatment with inhaled fluticasone propionate 50 micrograms or 100 micrograms was significantly more effective than theophylline in the treatment of mild-to-moderate asthma.

Efficacy of inhaled fluticasone propionate in asthma results from topical and not from systemic activity.

The objective of this study was to determine whether the therapeutic benefits of inhaled fluticasone propionate are mediated through topical or systemic effects. Two hundred seventy-four patients with asthma receiving beclomethasone dipropionate or triamcinolone acetonide during a 2-wk, single-blind, run-in period were randomized to inhaled fluticasone propionate powder 100 or 500 micrograms twice daily, oral fluticasone propionate 20 mg once daily, or placebo during a 6-wk treatment period. Patients receiving inhaled fluticasone propionate had a significantly greater probability of remaining in the study over time compared with patients receiving oral fluticasone propionate or placebo (p = 0.001). FEV1 and PEF rates at end point were significantly higher with inhaled fluticasone propionate treatment regimens than with oral fluticasone propionate (with the exception of PEF rates for inhaled fluticasone propionate 100 micrograms) or placebo treatments (p < or = 0.004). Systemic exposure to fluticasone propionate as assessed by trough plasma concentrations and/or 12-hr plasma concentration area under the curve analyses (AUC12) was higher with the oral fluticasone propionate than with the two inhaled fluticasone propionate treatment groups. The results of this study suggest that the therapeutic benefits of inhaled fluticasone propionate are mediated through topical effects in the lungs and not through systemic effects.

Effectiveness of fluticasone propionate in patients with moderate asthma: a dose-ranging study.

This study was undertaken to evaluate the efficacy and safety of fluticasone propionate, an inhaled corticosteroid, in adolescents and adults with moderate asthma who were previously taking inhaled corticosteroids. After a 2-week, open-label screening period, a double-masked, randomized, parallel-group, dose-ranging study was conducted over 12 weeks in 21 outpatient centers throughout the United States. Patients (N = 304) > or = 12 years of age with moderate asthma previously treated with inhaled corticosteroids and beta-sympathomimetic bronchodilators were enrolled. Patients were assigned to receive placebo or fluticasone propionate 100, 250, or 500 micrograms twice daily via a metered-dose inhaler without a spacer device. These doses refer to the amount of fluticasone propionate released from the valve of the metered-dose inhaler; the corresponding doses released from the activator of the metered-dose inhaler are 88 micrograms, 220 micrograms, and 440 micrograms, respectively. Between baseline and end point, mean values of forced expiratory volume in 1 second decreased 0.31 L in the placebo group and improved 0.39 L, 0.30 L, and 0.43 L in patients receiving 100-micrograms, 250-micrograms, and 500-micrograms fluticasone propionate, respectively. The differences between placebo and all treatment groups were statistically significant. More patients were withdrawn from placebo (72%) than from fluticasone propionate (13% to 16%) because of failure to meet predetermined asthma stability criteria. Differences in baseline-to-end point changes in morning peak expiratory flow rate, physician overall assessments and patient-rated assessment of symptoms, and albuterol use for symptom control also significantly favored each fluticasone propionate group over placebo. There were essentially no differences in efficacy among the three fluticasone propionate groups. Treatment-related adverse events occurred in 8% of placebo-treated patients and 13% to 15% of fluticasone propionate-treated patients; these events were mainly localized to the oropharynx/ larynx. A 12-week course of fluticasone propionate (100, 250, and 500 micrograms twice daily) was well tolerated and more effective than placebo based on maintenance of asthma stability, pulmonary function tests, physician and patient assessments, and rescue bronchodilator use. No dose-related effects were observed with the dosages of fluticasone propionate used in this study.

Inhaled salmeterol and fluticasone: a study comparing monotherapy and combination therapy in asthma.

BACKGROUND: The current stepwise approach to pharmacotherapy in the treatment of asthma includes the initiation of an inhaled corticosteroid with the addition of a long-acting inhaled bronchodilator if low dose inhaled corticosteroid fails to control asthma symptoms. OBJECTIVE: To determine whether initiation of salmeterol and fluticasone propionate treatment together improves asthma control greater than initiation of monotherapy with the individual agents alone with no additional safety risk in patients with asthma who had not previously been treated with inhaled corticosteroids. METHODS: A total of 136 male and female patients at least 12 years of age with asthma [forced expiratory volume in 1 second (FEV) between 50% and 80% of predicted] were randomized to twice daily salmeterol 42 microg, fluticasone propionate 88 microg, fluticasone propionate 220 microg, salmeterol 42 microg plus fluticasone propionate 88 microg, salmeterol 42 microg plus fluticasone propionate 220 microg, or placebo for 4 weeks. RESULTS: Patients treated with salmeterol combined with fluticasone propionate had improvements over baseline in FEV at endpoint that were at least twice as great (0.6 to 0.7 L) as improvements in patients treated with salmeterol (0.3 L) or fluticasone propionate alone (0.3 L) (P < .05). Patient-rated data (peak expiratory flow, asthma symptom scores, percent of days with no asthma symptoms) confirmed greater (P < .05) mean change from baseline improvements after combined treatment compared with fluticasone propionate alone. No clinically significant differences were noted between treatment groups in any safety measurement. CONCLUSION: Initiation of maintenance therapy with salmeterol and fluticasone propionate in patients with asthma treated with short-acting beta2-agonists alone provides greater improvements in pulmonary function and symptom control than initiation of maintenance therapy with fluticasone propionate alone.

Once daily intranasal fluticasone propionate is effective for perennial allergic rhinitis.

The efficacy of intranasal fluticasone propionate 200 micrograms once daily or 100 micrograms twice daily in treating perennial allergic rhinitis was evaluated in a randomized, double-blind, placebo-controlled study of 24 weeks' duration in 365 patients. Clinician-rated and patient-rated total nasal symptom severity scores were improved within 1 week of treatment with either regimen of fluticasone propionate and improvement was maintained over the 24-week treatment period. Clinician-rated overall evaluation indicated a significantly better response in the two fluticasone propionate groups compared with the placebo group. All efficacy evaluations indicated no difference in response between the fluticasone propionate 200 micrograms once-daily and 100 micrograms twice-daily groups. Patients in both fluticasone propionate groups had significantly less nasal obstruction upon awakening than the placebo group at all assessment periods. Fewer patients in either fluticasone propionate group used antihistamine rescue medication compared with the placebo group. The percentage of patients with nasal eosinophils and basophils at the end of the 24-week treatment period was significantly lower in both fluticasone propionate groups compared with the placebo group. Safety evaluations indicated that intranasal fluticasone propionate was as safe as placebo when given as 200 micrograms once daily or 100 micrograms twice daily. The incidence of drug-related adverse events was similar among the fluticasone propionate and placebo groups except for the incidence of epistaxis and blood in nasal mucus which was somewhat higher in the fluticasone propionate twice-daily group. There was no changes in the opthalmic examinations to suggest corticosteriod-induced posterior subcapsular cataract formation.(ABSTRACT TRUNCATED AT 250 WORDS)

Adrenal suppression with high doses of inhaled fluticasone propionate and triamcinolone acetonide in healthy volunteers.

STUDY OBJECTIVE: This study was conducted to compare the adrenal suppression of inhaled fluticasone propionate and triamcinolone acetonide in healthy volunteers, both given via their respective pressurised metered dose inhaler (pMDI) devices at high doses within the manufacturers recommended dose range. DESIGN: We used a single (investigator) blind, randomised, crossover design comparing a total daily dose of 1.625 mg fluticasone propionate delivered via a pMDI, 1.60 mg daily of triamcinolone acetonide delivered via a pMDI with integrated spacer, or placebo pMDI; each drug was given in two divided doses at 0800 hours and 2200 hours over a 24-h period. Each drug treatment was separated by a 1-week washout. PATIENTS: Twelve normal subjects mean age 27.5 years were studied. MEASUREMENTS: Blood samples were taken for 0800 hours plasma cortisol, i.e. 10 h following the second dose. Ten hour urine collections (2200 hours until 0800 hours) were taken for urinary cortisol and creatinine excretion. RESULTS: For the 0800 hours plasma cortisol (geometric mean, nmol.1(-1) compared with placebo (353) fluticasone propionate (138) produced significant (P < 0.05) suppression (2.57-fold difference), whereas triamcinolone acetonide (263) did not (1.34-fold difference). Fluticasone propionate produced a 1.91-fold greater adrenal suppression than triamcinolone acetonide (95% CI 1.10 to 3.33). Individual subjects with abnormally low 0800 hours cortisol values < 150 nmol.1(-1) (< 5.4 micrograms/dl) were n = 4 for fluticasone propionate and n = 0 for triamcinolone acetonide. Overnight urinary cortisol/creatinine ratio (geometric mean, nmol/mmol) did not show any difference between fluticasone propionate (1.48) and triamcinolone acetonide (1.60), with both producing significant suppression versus placebo (4.01): triamcinolone acetonide 2.50-fold difference (95% CI 1.45-4.24); fluticasone propionate 2.71-fold difference (95% CI 1.57-4.69). CONCLUSION: Fluticasone propionate 1.625 mg/day (pMDI) produced an approximately two-fold greater adrenal suppression of 0800 hours plasma cortisol than triamcinolone acetonide 1.60 mg per day (Oral Inhaler) when given twice daily, and one third of subjects with fluticasone had abnormally low 0800 hours cortisol values < 150 nmol.1(-1) (< 5.4 micrograms.dl-1. There were no differences between the drugs for urinary cortisol excretion. Further dose-ranging studies are required at steady-state in asthmatic subjects in order to see whether differences occur at lower doses on the steep part of the dose-response curve for both plasma and urinary cortisol suppression.
