Fluticasone propionate was compared with beclomethasone dipropionate for the treatment of allergic rhinitis in a multicenter, double-blind, randomized, placebo-controlled study during the mountain cedar (Juniperus ashei) pollination season in central Texas. Adults (n = 313) with moderate to severe symptoms were treated with fluticasone propionate aqueous nasal spray 200 micrograms once a day or beclomethasone dipropionate aqueous nasal spray 168 micrograms twice a day or placebo for 2 weeks. Fluticasone propionate administered once daily and beclomethasone dipropionate administered twice daily were equally effective as assessed by clinician- and patient-rated scores for nasal obstruction, rhinorrhea, sneezing, and nasal itching throughout the treatment and follow-up periods. Both regimens were more effective than placebo. Adverse events were related to topical administration and were similar in frequency and nature in all three treatment groups. Fluticasone propionate and beclomethasone dipropionate displayed a similar safety profile that did not differ from placebo. We conclude that fluticasone propionate aqueous nasal spray administered as 200 micrograms once daily in the morning is as safe and effective as beclomethasone dipropionate aqueous nasal spray administered as 168 micrograms twice daily for seasonal allergic rhinitis.

Fluticasone propionate aqueous nasal spray (FPANS) contains fluticasone propionate, which is a new topically active glucocorticoid with approximately twice the potency of belcomethasone dipropionate. In this European multicentre study, 143 children with seasonal allergic rhinitis were recruited: 47 received FPANS 100 micrograms once a day (od), 46 received FPANS 200 micrograms od, and 50 patients received placebo od, for 4 weeks. Treatment efficacy was assessed using diary card nasal symptom scores for sneezing, rhinorrhoea, blockage and itching, and eye watering/irritation. Patients receiving FPANS 100 micrograms or FPANS 200 micrograms demonstrated statistically significant improvements in median nasal symptom scores in all the symptoms recorded, when compared with placebo. There were no statistically significant differences between the FPANS 100 micrograms and FPANS 200 micrograms groups in improvement in nasal symptom scores. There was no effect on eye watering/irritation symptoms which could be attributed to either FPANS 100 micrograms or FPANS 200 micrograms when compared with placebo. Use of rescue antihistamine medication was significantly reduced in the FPANS 100 micrograms group when compared with placebo. The adverse events profile was similar in all three treatment groups, and the events reported were generally mild and related to the patients' rhinitis.

The aim of the study was to investigate the effect of short-term treatment with fluticasone propionate on the response to nasal allergen challenge in patients with allergic rhinitis. Responses to nasal allergen challenge were assessed subjectively by recording symptom scores on visual analogue scales, and objectively by measuring histamine, PGD2 and LTC4 in nasal lavage and by measuring nasal inspiratory peak flow following challenge. Nasal allergen challenge resulted in an increase in all symptom scores (P < 0.05); an increase in histamine and PGD2 (P < 0.05), and a decrease in nasal inspiratory peak flow at 1 h, 5 h and 7 h following challenge (P < 0.05). The allergen-induced changes in symptom scores, mediator levels and nasal inspiratory peak flow were attenuated by treatment with fluticasone propionate (P < 0.05 for all parameters measured). Post-challenge nasal obstruction was decreased by 45%; sneezing, itching and rhinorrhoea by 73, 78 and 80% respectively in the group as a whole comparing scores whilst on fluticasone propionate with those on no therapy. Fluticasone propionate, 200 micrograms twice daily for 2 weeks is effective in reducing significantly the early and late response to nasal allergen challenge.

Fluticasone propionate is a potent fluorinated corticosteroid used for the topical therapy of dermatoses and as inhalation therapy for bronchial asthma and allergic rhinitis. This agent has a good safety profile with a low propensity for systemic side effects, such as suppression of the hypothalamic-pituitary-adrenal (HPA) axis, and a low incidence of local side effects such as pruritus, burning, or skin atrophy. The pharmacologic properties of fluticasone propionate-including high lipophilicity, high selectivity and affinity for the glucocorticoid receptor, low systemic absorption, and rapid metabolism and clearance-combine to give fluticasone propionate a high therapeutic index.

The clinical efficacy and safety of fluticasone propionate ointment, 0.005%, were compared with those of its vehicle in the treatment of moderate-to-severe eczema of long duration in two multicenter, double-blind, vehicle-controlled, randomized studies. One of the two study medications (up to 100 gm/week) was applied topically to the affected areas of the body twice daily for up to four consecutive weeks. Drug efficacy was measured in terms of three variables: the physician's gross assessment of clinical response of the target lesion, severity scores of individual signs and symptoms, and the patient's subjective assessment of treatment effects. Efficacy and safety were evaluated after seven, fourteen, twenty-one, and twenty-eight days of treatment. The total number of patients in the two studies was 372 (203 in study 1 and 169 in study 2). Fluticasone propionate ointment, 0.005%, was more effective than vehicle at all postbaseline visits in both studies (study 1 P < or = 0.015, study 2 P < or = 0.018). In study 1, approximately 80% of the patients on fluticasone were rated as cleared, excellent, or good by the investigators at treatment endpoint, compared with 38% of those receiving vehicle. In study 2, the sum of 80% of the fluticasone-treated patients was rated as cleared, excellent, or good by the investigators at the end of the study, compared with 34% of those receiving vehicle. The beneficial effect of fluticasone ointment, 0.005%, was early and sustained and was particularly noticeable for pruritus, erythema, and skin thickening. In study 1, no drug-related adverse events were reported in the fluticasone group. Four patients (4.3%) in the vehicle group experienced a total of four drug-related adverse events. The most common was burning/stinging, reported by two patients. In study 2, two patients (2.4%) in the fluticasone-treated group and three (4.1%) in the vehicle group reported a total of five drug-related adverse events, the most common event being pruritus (fluticasone group one patient, vehicle group two patients). These findings show that fluticasone propionate ointment, 0.005%, applied twice daily, is therapeutically superior to the vehicle and is well tolerated.

Intranasal corticosteroids have been shown to be more effective than oral antihistamines for the treatment of seasonal allergic rhinitis. However, there are some who question whether intranasally administered corticosteroids should be used due to potential systemic effects. Fluticasone propionate, a potent corticosteroid with high specificity for the glucocorticoid receptor, is available as an aqueous nasal spray for the treatment of allergic rhinitis. To determine whether the efficacy of fluticasone propionate aqueous nasal spray (FPANS) was due to direct topical effects on the nasal mucosa or to indirect systemic effects following absorption from the nasal mucosa or from the swallowed portion of an intranasal dose, FPANS 200 micrograms once daily was compared with oral fluticasone propionate 5 mg or 10 mg once daily or placebo for 2 weeks in patients with seasonal allergic rhinitis. These oral dosages were chosen to yield low but consistent plasma fluticasone propionate concentrations. Both clinician- and patient-rated scores for nasal obstruction, rhinorrhoea, sneezing, and nasal itching were significantly lower in the intranasal fluticasone propionate group compared with both oral fluticasone propionate groups. A separate placebo-controlled study was conducted in patients with perennial rhinitis to determine if administration of FPANS 200 micrograms once daily for 1 year was associated with adverse systemic effects. At the 1-year assessment, there were no significant effects on bone mineral density or on biochemical markers of bone turnover. Similarly, there was no evidence of posterior subcapsular cataracts nor of glaucoma. Furthermore, there were no significant effects on hypothalamic-pituitary adrenal axis function as assessed by plasma cortisol and 24-h urinary cortisol response to the 6-h cosyntropin stimulation test. These data confirm that the efficacy of FPANS for the treatment of allergic rhinitis results from direct topical effects, thus reducing the likelihood of adverse systemic 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.

The effectiveness and safety of fluticasone propionate aqueous nasal spray (200 micrograms once daily for 4 weeks) were compared with those of loratadine (10 mg once daily for 4 weeks) in 114 adults and adolescents with seasonal allergic rhinitis in this multicenter, double-blind, double-dummy, randomized, parallel-group study. Patients recorded their nasal symptoms (nighttime and daytime obstruction, sneezing, itching, rhinorrhea, and overall discomfort) using a 4-point scale (0 = no symptoms, 3 = very frequent symptoms) in daily diaries. Clinicians assessed patients' nasal symptoms (nighttime and daytime obstruction, sneezing, itching, and rhinorrhea) using a 4-point scale at every scheduled visit. Clinicians and patients assessed the overall effectiveness of treatment at the end of the study. Fluticasone propionate improved clinician-rated total nasal symptom scores (defined as the sum of five nasal symptoms) more than loratadine at the 2-week and 4-week assessments (P < or = 0.008). Clinicians give fluticasone propionate better global ratings than loratadine (P = 0.04). After 4 weeks of treatment, between-group differences in clinician-rated individual nasal symptoms favored fluticasone propionate (P < 0.05), with the exception of nasal itching (P = 0.11). These findings were confirmed by between-group differences in the percentages of symptom-free days calculated from patient-recorded daily diary-card data. Both treatments were well tolerated. The incidence of adverse events between groups was similar. Fluticasone propionate aqueous nasal spray 200 micrograms administered once daily in the morning was more effective than loratadine 10 mg administered once daily for the treatment of seasonal allergic rhinitis.

The currently available respiratory topical corticosteroids are all effective at reducing the nasal symptoms of itch, sneezing, rhinorrhoea and obstruction associated with allergic rhinitis. The mechanism of action of corticosteroids is related to their anti-inflammatory activities. They have been documented to prevent fluid exudation and reduce the number of circulating inflammatory cells, including lymphocytes, mast cells, basophils, eosinophils, macrophages, and neutrophils. This occurs through multiple mechanisms, e.g. eosinophil infiltration is suppressed by preventing cytokine production, reducing local mechanisms of tissue infiltration, and decreasing eosinophil survival. Furthermore, corticosteroids also reduce preformed and newly-generated mediators (e.g. histamine, tryptase, prostanoids, leukotrienes), and inhibit production of cytokines and chemokines by inflammatory cells (e.g. IL-1 through IL-6, IL-8, RANTES, TNF-alpha, IFN-gamma and GM-CSF). The currently available corticosteroids differ pharmacologically. Fluticasone propionate appears to have the greatest affinity for the glucocorticoid receptor, and binds more quickly and dissociates more slowly from the receptor compared with other corticosteroids, suggesting a more prolonged duration of action. Its increased specificity for respiratory tissue may lead to greater potency with less potential for systemic adverse effects. Fluticasone propionate has been compared with other corticosteroids in animal models for relative topical and systemic potency, and according to these data, it has the most favourable risk-benefit ratio.

Fluticasone propionate aqueous nasal spray (FPANS) is a topically active glucocorticoid which has been successfully used for the treatment of seasonal allergic rhinitis (SAR). Topical levocabastine is a highly selective H1 antagonist which has been proposed as an alternative treatment of SAR. The purpose of this study was to compare the clinical efficacy of two topical nasal treatments, FPANS and levocabastine, in the treatment of SAR. Additionally, the effect of treatments on nasal inflammation was examined during natural pollen exposure. A group of 288 adolescent and adult patients with at least a 2-year history of SAR to seasonal pollens participated in a multicenter, doubleblind, double-dummy, and placebo-controlled study. Patients were treated with either FPANS 200 microg, once daily (n = 97), or topical levocabastine, 200 microg, given twice daily (n = 96), or matched placebo (n = 95) for a period of 6 weeks, starting from the expected beginning of the pollen season. Clinically relevant pollens included Parietaria, olive, and grass. Assessment of efficacy was based on scores of daily nasal symptoms and on nasal cytology of nasal lavage. Nasal lavage was performed immediately before, during, and at the end of treatment in 39 patients. FPANS significantly increased the percentage of symptom-free days for nasal obstruction on waking and during the day, rhinorrhea, sneezing, and itching. FPANS provided a better control for night and day nasal obstruction (P<0.02 and P<0.01) and rhinorrhea (P<0.01) than levocabas tine. In addition, fewer patients treated with FPANS used rescue medication (P<0.025). The percentage of eosinophils in nasal lavage was reduced only during treatment with FPANS. The results of this study indicate that FPANS 200 microg, once daily, provides a better clinical effect than levocabastine 200 microg, twice daily, in patients with SAR. Unlike levocabastine, FPANS significantly attenuates nasal eosinophilia during pollen exposure, a feature which may explain its therapeutic efficacy.
