Background: MP-AzeFlu (Dymista; Meda Pharma GmbH & Co., KG), a formulation combining azelastine hydrochloride and fluticasone propionate in a single spray, is superior to fluticasone propionate alone in relieving symptoms and improving the quality of life of patients with allergic rhinitis.
Objectives: In this study, we evaluated whether the effect of AzeFlu, a generic drug manufactured from China, is equivalent to that of MP-AzeFlu.
Methods: In total, 679 patients were recruited for a multicentre, randomized, double-blind, original drug-controlled, and parallel-group clinical trial. Overall, 339 and 340 patients were administered with AzeFlu and MP-AzeFlu, respectively. Efficacy was assessed by changes in the reflective total nasal symptom score, the area under the curve of reflective total nasal symptom score changes over time, changes from baseline in individual nasal symptom scores, and the Rhinoconjunctivitis Quality of Life Questionnaire. In addition, a safety evaluation was simultaneously performed.
Results: AzeFlu and MP-AzeFlu reduced the reflective total nasal symptom score from baseline (AzeFlu -6.7 [standard deviation, 2.59]; MP-AzeFlu -6.7 [standard deviation, 2.76]; = 0.905) and improved nasal symptoms and quality of life (AzeFlu -62.3 [standard deviation, 33.59]; MP-AzeFlu -64.7 [standard deviation, 33.73]; = 0.394) in patients with allergic rhinitis. Significant differences were not observed between groups.
Conclusion: AzeFlu showed effects equivalent to those of MP-AzeFlu in this clinical trial and may benefit Chinese patients with allergic rhinitis. CTR20190189 (chinadrugtrials.org.cn/index.html).

Purpose: This study aims to identify anatomical variations inside and outside the maxillary sinus (MS), determine their prevalence and coexistence, and investigate their relationship with MS volume in individuals without MS pathology, using ImFusion Suite software.
Methods: Analysis of 330 paranasal CT scans obtained from the radiology archive (2018-2021) was performed using the ImFusion Suite program. Anatomical variations, including accessory ostium, Haller cells, ethmomaxillary sinus, concha anomalies, septa, and impacted teeth, were identified and their frequency of coexistence was determined.
A mixed-methods pilot study of domiciliary nasal high-flow therapy for breathlessness in people with chronic obstructive pulmonary disease who do not qualify for domiciliary long-term oxygen therapy.
Ther Adv Respir Dis
March 2025
Faculty of Medicine and Health Sciences, University of Melbourne, Parkville, VIC, Australia.
Background: High-flow nasal oxygen (HFNO) therapy delivers humidified, heated air with flow rates of up to 60 L/min with oxygen entrained. HFNO has advantages over conventional oxygen therapy, including precise and reliable fraction of inspired oxygen delivery, therefore is recommended as first-line treatment for people with acute hypoxaemic respiratory failure.
Objectives: This pilot study aimed to determine the feasibility and acceptability of domiciliary nasal high flow (NHF) without entrained oxygen for people with chronic obstructive pulmonary disease (COPD) and severe breathlessness.
