Adverse event mining for Breztri and Trelegy Ellipta based on the three international pharmacovigilance databases.
Article in Medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study aimed to identify adverse drug reaction (ADR) risk signals associated with budesonide/glycopyrrolate/formoterol (Breztri) and fluticasone furoate/umeclidinium/vilanterol (Trelegy Ellipta) to support clinical decision-making and risk management. ADR reports related to Breztri and Trelegy Ellipta from the FDA Adverse Event Reporting System (FAERS) database, Japanese Adverse Drug Event Report (JADER) database and Canada Vigilance Adverse Reaction database (Q3 2004 to Q2 2024) were analyzed. After deduplication, reports were categorized using Medical Dictionary for Regulatory Activities (MedDRA) to obtain System Organ Class (SOC) and preferred terms (PTs). Disproportionality analysis was conducted using reporting odds ratio (ROR) and proportional reporting ratio methods. Analysis of 394 Breztri and 18,866 Trelegy Ellipta FAERS reports (predominantly consumer-submitted, U.S.-originated) identified 47 signals across 11 SOCs for Breztri (e.g., "Drug delivery system issue" ROR = 411.16, "Intentional device misuse" ROR = 410.69) and 160 signals across 15 SOCs for Trelegy (e.g., "Chronic eosinophilic rhinosinusitis" ROR = 187.65, "Foreign body in mouth" ROR = 107.67), revealing unlabeled risks like administration errors and packaging confusion. JADER data reinforced respiratory risks (Breztri: Chronic obstructive pulmonary disease (COPD) ROR = 516.8; Trelegy: gastrointestinal fungal infection ROR = 413.11) and device-independent safety signals (e.g., Trelegy urinary retention ROR = 28.81), while CVARD highlighted region-specific concerns including Trelegy-associated vasculitis (pulmonary vasculitis n = 29) and Breztri hypertension (ROR = 7.82). Cross-database convergence confirmed core anticholinergic/cardiopulmonary risks, yet divergent signals, FAERS' device errors, JADER's infection prominence, and CVARD's immunological events, underscore geographic heterogeneity in adverse reaction profiles, necessitating tailored risk management strategies for inhaler therapies. Inhalation device-related ADRs were observed, with Breztri showing higher incidence than Trelegy Ellipta, likely due to its more complex device usage. These findings highlight the need for enhanced patient education by healthcare providers to ensure proper device use in COPD treatment. Although core respiratory and anticholinergic risks are globally relevant, infection profiles, device complications, and rare immunological events exhibit significant geographic heterogeneity, necessitating tailored risk mitigation strategies aligned with regional pharmacovigilance patterns.
