AI Article Synopsis
- This study compared the effectiveness of two asthma medications, fluticasone furoate (FF) and fluticasone propionate (FP), in adolescents and adults by analyzing 14 placebo-controlled trials with a total of 6640 participants.
- The results showed that both medications reached their maximum efficacy within two weeks, with FF showing slightly better improvement in lung function (measured as FEV) compared to FP at evaluated doses.
- Additionally, while both drugs had similar effects on asthma symptoms and quality of life when compared to placebo, FP reached its maximum effect at the highest dose, whereas FF did not, indicating potential differences in how these medications work.
Article Abstract
This study aimed to quantitatively compare the efficacy of fluticasone furoate (FF) and fluticasone propionate (FP) in adolescents and adults with asthma. We searched the PubMed and EMBASE databases for placebo-controlled trials that met the inclusion criteria. Pharmacodynamic models were established to describe the time-course of the primary outcome (trough forced expiratory volume in the first second [FEV ]). Secondary outcomes (asthma symptoms, quality of life and exacerbations) were also compared via a meta-analysis. A total of 14 articles were included in the analysis, involving 6640 subjects. The efficacy plateau of the two drugs could be reached in 2 weeks. The changes from the baseline in trough FEV (95% CI) at week 2 of FF at 200 and 100 μg/day were 0.168 L (0.064-0.199) and 0.127 L (0.048-0.163), respectively. The changes from the baseline in trough FEV (95% CI) at week 2 of FP at 1000, 500, 250 and 100 μg/day were 0.133 L (0.049-0.171), 0.127 L (0.043-0.163), 0.117 L (0.039-0.150) and 0.093 L (0.032-0.129), respectively. The efficacy of FP had reached a plateau at the maximum evaluated dose (1000 μg/day), while a plateau effect was not seen at the maximum evaluated dose of FF (200 μg/day). In terms of secondary outcomes, the relative effects of the two drugs relative to the placebo were similar and did not show obvious dose-effect relationships. In this study, the time-course and dose-effect characteristics of FP, FF and placebo were quantitatively evaluated, providing necessary quantitative information for asthma-related guidelines.

Persistent cough bothers many patients with asthma because it worsens their quality of life; therefore, it must be remedied immediately. The efficacy of triple therapy as a first-line treatment for cough remains unclear. To evaluate the effectiveness and safety of the triple therapy againts persistent cough, the clinical effect of regular treatment with fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) or placebo in adult patients with asthma was investigated.

Introduction: Escalation to single- or multiple-inhaler triple therapy (SITT; MITT) is a recommended option for patients with asthma who remain uncontrolled by medium-dose inhaled corticosteroid/long-acting β-agonist; however, characterization of elderly users of triple therapy is limited. This real-world cohort study describes demographics and clinical characteristics of elderly patients with asthma with and without comorbid chronic obstructive pulmonary disease (COPD) who are new users of triple therapy, and asthma treatment patterns preceding triple therapy initiation.
Methods: This retrospective cohort study used administrative claims data from the Optum Clinformatics Data Mart database.

Objective: Single inhaler triple therapy is widely used in Chronic Obstructive Pulmonary Disease (COPD) and asthma. This research aimed to analyze adverse events (AEs) associated with Budesonide/Glycopyrronium/Formoterol Fumarate (BUD/GLY/FOR) and Fluticasone Furoate/Umeclidinium/Vilanterol (FF/UMEC/VI).
Methods: This is a cross-sectional study.

Current in vitro cell-based methods, relying on single cell types, have structural and functional limitations in determining lung drug permeability, which is a contributing factor affecting both local and systemic drug levels. To address this issue, we investigated a 3D human lung airway model generated using a cell culture insert, wherein primary human lung epithelial and endothelial cells were cocultured at an air-liquid interface (ALI). To ensure that the cell culture mimics the physiological and functional characteristics of airway tissue, the model was characterized by evaluating several parameters such as cellular confluency, ciliation, tight junctions, mucus-layer formation, transepithelial electrical resistance, and barrier function through assaying fluorescein isothiocyanate-dextran permeability.

Introduction: Chronic obstructive pulmonary disease (COPD) is associated with exacerbations which can reduce quality of life and increase mortality. Single-inhaler triple therapy (SITT) is recommended for maintenance treatment of COPD among patients experiencing exacerbations despite dual-therapy use. This real-world comparative effectiveness study compared the impact of SITTs, fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI), and budesonide/glycopyrrolate/formoterol fumarate (BUD/GLY/FORM), on COPD exacerbations and mortality.
