RESUMO

BACKGROUND: Intranasal corticosteroids are effective in controlling allergic rhinitis (AR) symptoms; however, chronic administration of corticosteroids may suppress hypothalamic-pituitary-adrenal (HPA)-axis function. OBJECTIVE: To evaluate the effects of 6 weeks of treatment with beclomethasone dipropionate (BDP) hydrofluoroalkane nasal aerosol on HPA-axis function in subjects with perennial AR (PAR). METHODS: In this randomized, double-blind, placebo- and active-controlled study, subjects aged 12 to 45 years were randomized to receive BDP nasal aerosol 320 µg/day (n = 50), placebo (n = 46), or placebo/prednisone (prednisone 10 mg/day for the last 7 days of the treatment period [n = 11]). The primary end point was change from baseline in 24-hour serum cortisol (SC) weighted mean (expressed as geometric mean ratio [GMR]) in the BDP and placebo group after 6 weeks of treatment. RESULTS: Geometric SC-weighted mean values were similar in the BDP and placebo groups at baseline (9.04 and 8.45 µg/dL, respectively) and after 6 weeks (8.18 and 8.01 µg/dL, respectively). After 6 weeks of treatment, BDP was noninferior to placebo with respect to the ratio from baseline in SC-weighted mean (GMR: 0.96 [95% CI: 0.87, 1.06]). In contrast, 7 days of prednisone treatment substantially reduced geometric SC-weighted mean values from baseline (approximate 3-fold reduction [from 7.33 to 2.31 µg/dL]) compared with placebo. BDP nasal aerosol was well tolerated, and the safety profile was similar to that of placebo. CONCLUSION: Treatment with BDP nasal aerosol, 320 µg once daily, was not associated with HPA-axis suppression in adolescent and adult subjects with PAR. TRIAL REGISTRATION: Clinicaltrials.gov Identifier: NCT01133626.

RESUMO

Intranasal corticosteroids are recommended as first-line therapy for the treatment of the symptoms of persistent allergic rhinitis (AR). Since the phase-out of chlorofluorocarbon nasal aerosols, intranasal corticosteroids have been available only as aqueous nasal sprays. This study was designed to assess the efficacy, safety, and quality-of-life benefits of beclomethasone dipropionate (BDP) hydrofluoroalkane nasal aerosol in subjects with perennial AR (PAR). After a 7- to 21-day placebo run-in period, eligible subjects aged ≥12 years with PAR were randomized to 6 weeks of once-daily treatment with BDP nasal aerosol at 320 µg or placebo. Reflective and instantaneous total nasal symptom scores (rTNSS and iTNSS, respectively), Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) score, and physician-assessed total nasal symptom score were evaluated. The primary end point was change from baseline in average morning (A.M.) and evening (P.M.) subject-reported rTNSS over the 6-week treatment period. Safety and tolerability were also assessed. Treatment with BDP nasal aerosol showed significantly greater improvement in average A.M. and P.M. rTNSS compared with placebo (mean treatment difference, -0.84; 95% confidence interval, -1.2, -0.5; p < 0.001). Greater improvements in rTNSS were reported as early as day 1 and were maintained throughout the 6-week treatment period with the exception of day 2. Greater improvements were seen for all four individual nasal symptoms (nasal congestion, nasal itching, rhinorrhea, and sneezing) with BDP nasal aerosol compared with placebo. Similarly, significant improvements were seen in average A.M. and P.M. iTNSS (p < 0.001) and RQLQ score (p = 0.001) with BDP nasal aerosol compared with placebo. In addition, BDP nasal aerosol treatment was well tolerated, and its safety profile was comparable to that of placebo. This clinical study indicated that treatment with BDP nasal aerosol provides statistically significant and clinically meaningful nasal symptom relief accompanied by improved quality of life in subjects with PAR. Additionally, treatment with BDP nasal aerosol was well tolerated with a safety profile comparable to that of placebo. This study was part of the clinical trial NCT01134705 registered in www.ClinicalTrials.gov.

RESUMO

An aerosol formulation may be preferred by some allergic rhinitis (AR) patients, to avoid the "wet feeling" and nasal runoff associated with aqueous nasal corticosteroid sprays. Beclomethasone dipropionate (BDP) hydrofluoroalkane nasal aerosol is a recently developed, nonaqueous, nonchlorofluorocarbon formulation of BDP for the treatment of AR. This study was designed to evaluate the efficacy, safety, and quality-of-life benefits of BDP nasal aerosol in subjects with seasonal AR (SAR). Eligible subjects (≥12 years of age) enrolled in this 2-week study were randomized to either BDP nasal aerosol at 320 µg/day (n = 169) or placebo (n = 171). Efficacy assessments included reflective and instantaneous total nasal symptom scores (rTNSS and iTNSS, respectively), Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) score, reflective and instantaneous total ocular symptom scores (rTOSS and iTOSS, respectively), and physician-assessed total nasal symptom score (PNSS). Safety and tolerability were also assessed. Subjects receiving BDP nasal aerosol showed a significantly greater improvement from baseline in average A.M. and P.M. rTNSS versus placebo (treatment difference, -0.91; 95% confidence interval, -1.3, -0.5; p < 0.001) over 2 weeks of treatment. Greater improvements in rTNSS with BDP nasal aerosol compared with placebo were evident by day 2 and were maintained throughout the treatment period. Similarly, significant improvements were seen with BDP nasal aerosol in iTNSS (p < 0.001) and RQLQ score (p = 0.005) compared with placebo. Treatment with BDP nasal aerosol also resulted in greater improvements in rTOSS (p = 0.002), iTOSS (p = 0.003), and PNSS (p < 0.001) relative to placebo. BDP nasal aerosol was well tolerated and the overall safety profile was similar to placebo. Results from this clinical study indicated that BDP nasal aerosol provided significant AR symptom relief and was well tolerated in patients with SAR with an overall safety profile similar to placebo.

RESUMO

There is no standard meal plan or eating pattern that works universally for all people with diabetes. In order to be effective, nutrition therapy should be individualized for each patient/client based on his or her individual health goals; personal and cultural preferences; health literacy and numeracy; access to healthful choices; and readiness, willingness, and ability to change. Nutrition interventions should emphasize a variety of minimally processed nutrient dense foods in appropriate portion sizes as part of a healthful eating pattern and provide the individual with diabetes with practical tools for day-to-day food plan and behavior change that can be maintained over the long term.

RESUMO

BACKGROUND: Beclomethasone dipropionate (BDP) is an anti-inflammatory corticosteroid that is rapidly metabolized to the pharmacologically active monoester, beclomethasone-17-monopropionate (17-BMP). Recently, a hydrofluoroalkane (HFA)-propelled nasal aerosol formulation of BDP was developed to treat allergic rhinitis. However, the pharmacokinetic profile of BDP HFA nasal aerosol has not been previously investigated. OBJECTIVE: This study evaluated and compared the systemic levels of 17-BMP and BDP after a single dose of intranasally administered or orally inhaled BDP HFA in healthy subjects. METHODS: In this single-center, randomized, open-label, 3-period crossover study, healthy subjects received single doses of intranasal BDP HFA (80 and 320 µg) and orally inhaled BDP HFA (320 µg). The primary pharmacokinetic parameters assessed were area under the concentration-time curve until the last measurable value (AUC(last)) and C(max) for 17-BMP. For AUC(last) and C(max), point estimates for treatment differences and CIs were calculated on the log scale and then exponentiated to provide estimates of the geometric mean ratios (GMRs) and associated CIs. RESULTS: Thirty subjects were randomized to receive study medication (aged 18-45 years, 66.7% male). Mean plasma concentrations of 17-BMP after intranasal administration of BDP HFA (for both 80- and 320-µg doses) were substantially lower than that of orally inhaled BDP HFA (320 µg) across all time points. Mean AUC(last) values of 17-BMP for intranasal 80 µg, intranasal 320 µg, and orally inhaled 320 µg were 295.8, 1139.7, and 4140.3 pg·hr/mL, respectively. Mean C(max) values were 92.1, 262.7, and 1343.7 pg/mL, respectively. The GMR of AUC(last) for 17-BMP with intranasal BDP HFA 320 µg versus orally inhaled BDP HFA 320 µg was 0.275, indicating substantially lower systemic bioavailability with intranasal administration than with oral inhalation. Similarly, the GMR of AUC(last) for 17-BMP with intranasal BDP HFA 80 µg versus 320 µg was 0.260, suggesting approximate dose proportionality (4-fold difference). Pharmacokinetic results for BDP were similar to those seen for 17-BMP. All doses of intranasal and orally inhaled BDP HFA were well tolerated, and no treatment-related adverse events were reported. CONCLUSIONS: The results of this study suggest that 80 and 320 µg BDP HFA nasal aerosols have substantially lower systemic bioavailability than 320 µg orally inhaled BDP HFA in healthy subjects. All treatments were well tolerated. ClinicalTrials.gov identifier: NCT01537692.
