Pharmacologic and anti-IgE treatment of allergic rhinitis ARIA update (in collaboration with GA2LEN).

The pharmacologic treatment of allergic rhinitis proposed by ARIA is an evidence-based and step-wise approach based on the classification of the symptoms. The ARIA workshop, held in December 1999, published a report in 2001 and new information has subsequently been published. The initial ARIA document lacked some important information on several issues. This document updates the ARIA sections on the pharmacologic and anti-IgE treatments of allergic rhinitis. Literature published between January 2000 and December 2004 has been included. Only a few studies assessing nasal and non-nasal symptoms are presented as these will be discussed in a separate document.

Pill swallowing ability and training in children 6 to 11 years of age.

Despite the widespread view that children have difficulty swallowing pills, data are limited. In an observational cohort study, pill swallowing ability (small oral tablet) was assessed in children age 6 to 11 years. A total of 113 of 124 subjects (91%) swallowed a tablet using an ordinary cup or a patented pill cup. All 57 subjects who initially said they could swallow a pill were capable. Forty-seven learned with an ordinary cup and nine with the pill cup. Eleven did not learn. The majority of children (91%) age 6 to 11 years were able to successfully swallow a small oral tablet.

Nasal allergies and beyond: a clinical review of the pharmacology, efficacy, and safety of mometasone furoate.

Mometasone furoate nasal spray (MFNS; Nasonex, Schering-Plough Corporation, Kenilworth, NJ, USA) is an effective and well-tolerated intranasal corticosteroid approved for the prophylactic treatment of seasonal allergic rhinitis, and the treatment of perennial allergic rhinitis. MFNS is a potent molecule with a rapid onset of action and excellent safety and efficacy profiles. Having recently received approval for the treatment of nasal polyposis, data indicate that MFNS may also be effective in rhinosinusitis.

Montelukast improves symptoms of seasonal allergic rhinitis over a 4-week treatment period.

BACKGROUND: Proinflammatory mediators such as the cysteinyl leukotrienes are important in the pathophysiology of allergic rhinitis. This study evaluated the efficacy and tolerability of montelukast, a cysteinyl leukotriene receptor antagonist, given once daily in the morning for treatment of seasonal (fall) allergic rhinitis for 4 weeks. METHODS: This was a randomized, double-blind trial with a placebo run-in and a 4-week treatment period. Patients (n = 1079) with a history of allergic rhinitis and a positive skin test to seasonal pollen allergens were assigned to placebo, montelukast 10 mg, or loratadine 10 mg. Symptoms were assessed with a daily diary. RESULTS: Montelukast was more effective than placebo in improving scores for the primary endpoint of daytime nasal symptoms (P = 0.003) and the secondary endpoints of night-time, composite, and daytime eye symptoms, patient's and physician's global evaluations of allergic rhinitis, and rhinoconjunctivitis quality-of-life (P </= 0.006). The positive control loratadine also improved scores for the primary endpoint (P </= 0.001) and the majority of the secondary endpoints (P < 0.03). When analyzed by week, the treatment effect of montelukast was more persistent than loratadine over all 4 weeks of treatment. CONCLUSION: Montelukast provided effective relief of seasonal allergic rhinitis symptoms when given once daily in the morning, showed significant and sustained improvement in symptoms of allergic rhinitis over 4 weeks of treatment, and was well-tolerated.

Increasing asthma knowledge and changing home environments for Latino families with asthmatic children.

We tested an asthma education program in 204 underserved Latino families with an asthmatic child. The education program consisted of one or two sessions delivered in each family's home in the targeted participant's preferred language by a bilingual, bicultural educator. We encouraged, but did not require, attendance by the child. The curriculum was culturally-tailored, and all participants received education on understanding asthma, preventing asthma attacks, and managing asthma. Outcomes included change in asthma knowledge and change in home environment asthma management procedures. Asthma knowledge increased significantly (39 to 50% correct from pre- to post-test, P < 0.001) and participants made significant changes to the child's bedroom environment (mean number of triggers decreased from 2.4 to 1.8, P < 0.001; mean number of controllers increased from 0.7 to 0.9, P < 0.001). The results support the value of asthma education and its importance in the national agenda to reduce health disparities among minorities.

Safety of fexofenadine in children treated for seasonal allergic rhinitis.

BACKGROUND: The incidence of allergic rhinitis in children is increasing. OBJECTIVE: To evaluate the safety of fexofenadine HCI in children ages 6 through 11 years for treatment of seasonal allergic rhinitis. METHODS: Two large, double-blind, randomized, placebo-controlled, parallel studies with identical protocols included patients with a positive skin test to fall allergen(s) and allergic rhinitis symptoms. Patients were randomized to receive fexofenadine 15, 30, or 60 mg or placebo twice daily for 2 weeks after a 1-week placebo lead-in. Safety was evaluated through adverse event reporting, electrocardiograms, and pre- and posttreatment laboratory panels and physical examinations. RESULTS: A total of 875 patients from both studies were eligible for safety analyses. Ten patients (5 on placebo, 5 on fexofenadine) discontinued because of an adverse event; no event that resulted in discontinuation was judged to be caused by study medication. Incidence of adverse events was similar in active and placebo groups, and did not increase with increasing fexofenadine dose: 36.2% (83 of 229) in the placebo group versus 35.3% (79 of 224), 36.8% (77 of 209), and 34.7% (74 of 213) in the 15, 30, and 60 mg twice-daily fexofenadine groups, respectively. Headache was the most commonly reported adverse event (6.6%, 8.0%, 7.2%, and 9.4% in the placebo, 15, 30, 60 mg twice-daily fexofenadine groups, respectively). Clinical, vital sign, electrocardiogram, and laboratory measures were similar in active and placebo groups. There was no statistically significant mean change from baseline in any electrocardiogram parameter after fexofenadine treatment. CONCLUSIONS: Fexofenadine, 15, 30, and 60 mg twice daily, was safe and well tolerated in this large pediatric patient population.

Onset of therapeutic effect of fluticasone propionate aqueous nasal spray.

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.

Desloratadine: A new, nonsedating, oral antihistamine.

Desloratadine is a new, selective, H(1)-receptor antagonist that also has anti-inflammatory activity. In vitro studies have shown that desloratadine inhibits the release or generation of multiple inflammatory mediators, including IL-4, IL-6, IL-8, IL-13, PGD(2), leukotriene C(4), tryptase, histamine, and the TNF-alpha-induced chemokine RANTES. Desloratadine also inhibits the induction of cell adhesion molecules, plateletactivating factor-induced eosinophil chemotaxis, TNF-alpha-induced eosinophil adhesion, and spontaneous and phorbol myristate acetate-induced superoxide generation in vitro. In animals desloratadine had no effect on the central nervous, cardiovascular, renal, or gastrointestinal systems. Desloratadine is rapidly absorbed, has dose-proportional pharmacokinetics, and has a half-life of 27 hours. The absorption of desloratadine is not affected by food, and the metabolism and elimination are not significantly affected by the subject's age, race, or sex. There are no clinically relevant interactions between desloratadine and erythromycin, ketoconazole, or grapefruit juice. Desloratadine is not a significant substrate of the P-glycoprotein transport system. Once daily administration of desloratadine rapidly reduces the nasal and nonnasal symptoms of seasonal allergic rhinitis, including congestion. In patients with seasonal allergic rhinitis and concomitant asthma, desloratadine treatment was also associated with significant reductions in total asthma symptom score and use of inhaled beta(2)-agonists. Use of desloratadine in patients with chronic idiopathic urticaria was associated with significant reductions in pruritus, number of hives, size of the largest hive, and interference with sleep and daily activities. Clinical experience in over 2300 patients has shown that the adverse event profile of desloratadine is similar to that of placebo; desloratadine has no clinically relevant effects on electrocardiographic parameters, does not impair wakefulness or psychomotor performance, and does not exacerbate the psychomotor impairment associated with alcohol use.

Quality of life in adults and children with allergic rhinitis.

Quality of life, when referring to an individual's health, is called health-related quality of life (HRQL). HRQL focuses on patients' perceptions of their disease and measures impairments that have significant impact on the patient. Similar symptoms may vary in their effect on different individuals; the goal of therapy should be to reduce impairments that patients consider important. HRQL can be measured with generic or specific questionnaires. Specific questionnaires may be more sensitive and are much more likely to detect clinically important changes in patients' impairments. Specific questionnaires used to assess HRQL in rhinitis are the Rhinoconjunctivitis Quality of Life Questionnaire, the Adolescent Rhinoconjunctivitis Quality of Life Questionnaire, and the Pediatric Rhinoconjunctivitis Quality of Life Questionnaire. HRQL issues in adult rhinitis patients include fatigue, decrease in energy, general health perception, and social function; impairment of HQRL generally increases with increasing degree of symptoms and severity of disease. In children, HRQL issues include learning impairment, inability to integrate with peers, anxiety, and family dysfunction. Comorbid disorders often associated with rhinitis, including sinusitis, otitis media, and frequent respiratory infections, can further compromise HRQL. Pharmacologic treatments can have both positive and negative effects on HRQL. Agents that have troublesome adverse effects such as sedation can have a negative impact, whereas nonsedating antihistamines and intranasal cortico-steroids can significantly improve HRQL in patients of all ages with rhinitis.

Onset-of-action for antihistamine and decongestant combinations during an outdoor challenge.

BACKGROUND: Medications containing a combination antihistamine-decongestant are commonly used for allergic rhinitis yet onset-of-action comparisons for symptom relief after a single dose have not been performed. OBJECTIVE: To determine the onset of symptom relief and efficacy of antihistamine-decongestant medications (acrivastine-pseudoephedrine and loratadine-pseudoephedrine) compared with placebo in an outdoor park. METHODS: This study was conducted during the spring of 1997 using a double-blind, placebo-controlled design. Patients completed baseline rhinitis symptom diaries from 7:30 to 9:30 AM. Subjects with qualifying symptom scores received one dose of either acrivastine-pseudoephedrine, loratadine-pseudoephedrine, or placebo at 10:00 AM. Symptom diaries were recorded for the next 4 hours. RESULTS: Of 593 patients randomized to treatment, 592 were included in efficacy analysis. Acrivastine-pseudoephedrine and loratadine-pseudoephedrine demonstrated a mean onset-of-action by 45 and 30 minutes respectively for total symptom and rhinitis symptom scores for the five sites. Onset-of-action for nasal congestion scores was 45 minutes for both medications. Sites having higher pollen exposure (>100 pollen grains over 6 hours) demonstrated a difference between the antihistamine combinations: acrivastine-pseudoephedrine had an onset of action at 45 minutes for total symptom and rhinitis symptom scores, and 15 minutes for nasal congestion scores whereas loratadine-pseudoephedrine had onset-of-action for nasal congestion score of 105 minutes but failed to reach significance at any timepoint for total symptom and rhinitis symptom scores. CONCLUSIONS: Both antihistamine-decongestant combinations demonstrate an onset-of-action within 60 minutes of administration but under conditions of higher pollen exposure, the acrivastine combination was more effective for total symptoms, rhinitis symptoms, and nasal congestion with an onset-of-action within 45 minutes for rhinitis symptoms and 15 minutes for congestion.

Quality of life in patients with allergic rhinitis.

LEARNING OBJECTIVES: Reading this article will familiarize the practitioner with ongoing efforts to measure the effects of allergic rhinitis symptoms and its treatments on the health-related quality of life (HRQOL) of patients. The reader will learn about instruments used to collect HRQOL data, results of studies showing the burden of illness and the effects of treatments on HRQOL, and efforts to interpret the clinical relevance of changes in HRQOL status. DATA SOURCES: Information was gleaned from articles listed in MEDLINE regarding HRQOL in allergic rhinitis between 1966 and 2000 (English language only), and from the personal experiences of the authors. STUDY SELECTION: Questionnaire validation studies and representative controlled trials employing measures to assess the effects of allergic rhinitis symptoms and its treatments on HRQOL are described. RESULTS FROM THIS REVIEW: Allergic rhinitis symptoms can have detrimental effects on the physical, psychologic, and social aspects of patients' lives. Clinical trial data suggest a variety of pharmacologic therapies can significantly improve HRQOL in patients with allergic rhinitis. Validated questionnaires are now available that can easily be used in clinical practice to measure the effects of interventions on HRQOL for individual patients. CONCLUSIONS: Evaluating the effects of interventions on HRQOL may be particularly important in a non-life-threatening condition such as rhinitis. Health-related quality of life measures can be used to indicate the risk/benefit and the cost/benefit ratios of competing treatment options. Clinicians and policy makers are already using HRQOL data to evaluate results of medical interventions to guide patient management and reimbursement decisions.

Role for cysteinyl leukotriene receptor antagonist therapy in asthma and their potential role in allergic rhinitis based on the concept of "one linked airway disease".

OBJECTIVE: This review focuses on the shared pathophysiology of asthma and allergic rhinitis. The similarities illustrate the "one linked airway disease" concept, a unifying theory of these upper and lower airway inflammatory disorders. Since leukotrienes are mediators in both conditions, studies have been performed to assess the potential therapeutic role of cysteinyl leukotriene antagonists. The purpose of this paper is to provide an overview of the accumulating data concerning these agents in treating asthma and allergic rhinitis. DATA SOURCES: Relevant publications obtained from a literature review. STUDY SELECTION: Relevant publications on the topics of leukotrienes, leukotriene receptor antagonists, asthma, and allergic rhinitis were critically evaluated. RESULTS AND CONCLUSIONS: Studies to date have documented the efficacy of cysteinyl leukotriene receptor antagonists for asthma. The pathophysiology of allergic rhinitis and its similarities to asthma suggest that these agents could play a significant therapeutic role in managing this upper airway disorder. Because the leukotriene antagonists are oral agents, they may be valuable in treating not only either condition but also both at the same time when they coexist. They appear to be beneficial when prescribed as the initial medicine and when used in conjunction with other therapies.

Concomitant montelukast and loratadine as treatment for seasonal allergic rhinitis: a randomized, placebo-controlled clinical trial.

BACKGROUND: Nasal challenge studies have suggested histamine and cysteinyl leukotrienes are important proinflammatory mediators in allergic rhinitis. This study was designed to determine the efficacy of montelukast, a cysteinyl leukotriene receptor antagonist, administered alone or concomitantly with loratadine, an H(1)-receptor antagonist, in seasonal allergic rhinitis. OBJECTIVE: The purpose of this study was to determine the effect of concomitant use of montelukast and loratadine in the treatment of seasonal allergic rhinitis. METHODS: In this multicenter (N = 12) double-blind, randomized, parallel-group, placebo-controlled 2-week trial, 460 men and women, aged 15 to 75 years, with spring seasonal allergic rhinitis were randomly allocated to receive 1 of the following 5 treatments: montelukast 10 or 20 mg, loratadine 10 mg, montelukast 10 mg with loratadine 10 mg, or placebo, once daily in the evening. The primary end point was daytime nasal symptoms score (average of congestion, rhinorrhea, itching, and sneezing). Other end points were eye symptoms, nighttime symptoms, individual daytime nasal symptoms, global evaluations (patient's and physician's), and rhinoconjunctivitis quality-of-life scores. RESULTS: Concomitant montelukast with loratadine improved the primary end point significantly (P <.001) compared with placebo and each agent alone. Compared with placebo, montelukast with loratadine also significantly improved eye symptoms, nighttime symptoms, individual daytime nasal symptoms, global evaluations, and quality of life. Montelukast alone and loratadine alone caused modest improvements in rhinitis end points. All treatments were similarly well tolerated. CONCLUSIONS: Concomitant montelukast with loratadine provided effective treatment for seasonal allergic rhinitis and associated eye symptoms with a safety profile comparable with placebo.

Added relief in the treatment of acute recurrent sinusitis with adjunctive mometasone furoate nasal spray. The Nasonex Sinusitis Group.

BACKGROUND: Intranasal glucocorticoids are effective in the treatment of allergic rhinitis. Their effectiveness as an anti-inflammatory adjunct in the treatment of acute recurrent sinusitis has not been adequately established in a controlled clinical study. OBJECTIVE: The purpose of this study was to test the hypothesis that intranasal corticosteroid treatment produces additional relief in the treatment of acute sinusitis with oral antibiotics. METHODS: Patients who were 12 years old and older with a history of recurrent sinusitis were treated while experiencing a new episode of acute sinusitis, which was diagnosed by symptoms and confirmed by computed tomography scan of the paranasal sinuses. Patients were treated for 21 days with amoxicillin clavulanate potassium and randomized to receive concurrent mometasone furoate nasal spray (MFNS; Nasonex [400 microg, twice daily]; n = 200 patients) or placebo spray (twice daily; n = 207 patients). Symptom scores for headache, facial pain, congestion, purulent rhinorrhea, postnasal drip, and cough were recorded at baseline and throughout treatment. RESULTS: Baseline symptom scores showed a moderate level of symptom severity comparable in both groups. Patient-recorded twice daily symptom scores showed that adjunctive treatment with MFNS caused a significantly greater decrease in total symptom score (primary efficacy variable) and in individual scores of inflammatory symptoms associated with the obstruction process (headache, congestion, and facial pain) compared with placebo. Symptoms associated with the secretory processes were improved to a lesser degree. Therapy-related local adverse events were not significantly different between groups. CONCLUSION: The addition of intranasal corticosteroid, MFNS 400 microg twice daily, to antibiotics significantly reduces symptoms of acute sinusitis compared with antibiotic treatment alone.

Involuntary smoking and asthma.

Involuntary smoking is the third leading preventable cause of death, and among children it causes lower respiratory infections, middle ear disease, sudden infant death syndrome, and asthma. Half the world's children may be exposed to environmental tobacco smoke (ETS), exacerbating symptoms in 20% of children with asthma. Recent studies have reinforced previous conclusions that ETS exposure causes onset of childhood asthma and exacerbation of symptoms throughout life. The exact mechanisms by which this is accomplished are still unclear, as are the relative contributions of prenatal versus postnatal exposure. However, favorable health outcomes can be attained with reduced exposure. Among the few studies of ETS exposure reduction interventions, low-intensity advice methods appeared ineffective, and counseling parent smokers appeared successful. Direct counseling of school-aged children to avoid ETS has yet to be tested. Community norms may need to shift further in favor of protecting children and others from ETS before minimal interventions can be successful. This will require combined and ongoing efforts of the medical and public health establishments, in concert with legislation mandating tobacco-free public places and with ETS-related media campaigns.

Detection of growth suppression in children during treatment with intranasal beclomethasone dipropionate.

OBJECTIVE: Intranasal beclomethasone dipropionate (BDP) has generally been considered to have no systemic activity at recommended doses, but the potential for long-term effects on growth has not previously been evaluated. This study was undertaken to assess the effects of 1 year of treatment with intranasal BDP on growth in children. STUDY DESIGN: In this double-blind, randomized, parallel-group study, 100 prepubertal children 6 to 9 years old with perennial allergic rhinitis were treated with aqueous BDP 168 microg twice daily (n = 51) or placebo (n = 49) for 1 year. Subjects' baseline heights were required to be between the 5th and 95th percentile, and skeletal age as determined by left wrist radiograph was required to be within 2 years of chronological age. Washout periods for medications known to affect growth, including other forms of corticosteroids, were established, and these medications were prohibited during the study. However, short courses of oral prednisolone lasting no more than 7 days, and short courses of dermatologic corticosteroids lasting no more than 10 days, were allowed. Height was measured with a stadiometer after 1, 2, 4, 6, 8, 10, and 12 months of treatment. The hypothalamic-pituitary-adrenocortical axis was assessed by measurements of 8 AM basal cortisol concentrations and response to. 25 mg cosyntropin stimulation. The primary safety parameter was the rate of change in standing height. Statistical analyses were based on all randomized subjects who received at least 1 dose of medication (intent-to-treat principle). The rate of change in standing height was analyzed for all subjects who entered the study and for those completing the full 12 months of treatment (n = 80). The rate of change in standing height over the 1-year study was calculated as the slope of a linear regression line fitted to each subject's height measurements over time. Because there was a statistically significant between-group difference in standing height at baseline, an analysis of covariance was performed for all analyses of standing height data. RESULTS: Of the 100 subjects enrolled, 90 completed the study. The 2 treatment groups were generally comparable at baseline; however, at baseline, mean age and mean height were significantly greater in the BDP treatment group that the in placebo treatment group. In both analyses, overall growth rate was significantly slower in BDP-treated subjects than placebo-treated subjects. The mean change in standing height after 1 year was 5.0 cm in the BDP-treated subjects compared with 5.9 cm in the placebo-treated subjects. The difference in growth rates was evident as early as the 1-month treatment visit, suggesting that the effect on growth occurred initially. The growth-suppressive effect of BDP remained consistent across all age and gender subgroups, and among subjects with and without a previous history of corticosteroid use. Use of additional exogenous corticosteroids during the study was similar in both groups and did not affect the results. Because there was a baseline imbalance in height, a supplemental analysis of the differences in prestudy growth rates was performed. This analysis found no baseline imbalance in prestudy growth rates. To determine whether the difference in growth rates during the study could be attributed to preexisting growth rates, a z score analysis was performed. The heights of both groups were normalized at baseline and at the end of the study using the US National Center for Health Statistics data for mean and standard deviations of height. This analysis confirmed that the difference in growth rates between the 2 groups was primarily attributable to the treatment rather than to any preexisting difference in growth. Additional analyses confirmed that the results were not influenced by outlier values. No significant between-group difference were found in the hypothalamic-pituitary-adrenocortical axis assessments. No unusual adverse events were observed. (ABSTRACT

A dose-ranging study of mometasone furoate aqueous nasal spray in children with seasonal allergic rhinitis.

BACKGROUND: The efficacy and safety of mometasone furoate aqueous nasal spray (MFNS; Nasonex) 200 microg once daily for the treatment and prophylaxis of seasonal allergic rhinitis (SAR) and treatment of perennial rhinitis have been demonstrated in adults. However, the dose response of MFNS in pediatric patients has not yet been characterized. OBJECTIVE: This study was conducted to determine the dose-response relationship of 3 different doses of MFNS in a pediatric population. METHODS: This was a multicenter, double-blind, active- and placebo-controlled study of 679 children 6 to 11 years of age with histories of SAR and documented positive skin test responses. Patients were randomized to one of the following treatment groups for 4 weeks: MFNS 25 microgram once daily, MFNS 100 microgram once daily, MFNS 200 microgram once daily, beclomethasone dipropionate 84 microgram twice daily (168 microgram/day), or placebo. Physician evaluations were performed at days 4, 8, 15, and 29, and patient evaluations were analyzed for days 1 to 15 and 16 to 29. RESULTS: The mean reduction from baseline in physician-evaluated total nasal symptom scores at day 8 (the primary efficacy variable) was significantly greater in the MFNS and beclomethasone dipropionate groups than in the placebo group (P </=.02). No significant differences were observed among the 3 MFNS groups. However, as treatment continued, symptoms in patients treated with MFNS 100 or 200 microgram once daily continued to improve, whereas those treated with MFNS 25 microgram once daily demonstrated little further improvement. By day 29, MFNS 100 and 200 microgram once daily both were significantly more effective than MFNS 25 microgram once daily in relieving symptoms of SAR, but MFNS 200 microgram provided no additional benefit over MFNS 100 microgram. All doses of MFNS were well tolerated, and cosyntropin stimulation tests performed before and after treatment found no evidence of hypothalamic-pituitary-adrenal axis suppression. CONCLUSION: These results indicate that the most appropriate therapeutic dosage of MFNS in the treatment of SAR in children 6 to 11 years of age is 100 microgram once daily. In addition, MFNS at doses up to 200 microgram once daily for 4 weeks was well tolerated and had no detectable effects on hypothalamic-pituitary-adrenal axis function.
