| アブストラクト | BACKGROUND: Asthma and chronic obstructive pulmonary disease are common respiratory disorders with significant global health implications. Budesonide/formoterol (Symbicort) is a fixed-dose inhaler combining budesonide and formoterol fumarate dihydrate, widely used for disease management. While its clinical efficacy is well established, there is an increasing number of adverse drug event (ADE) reports, highlighting the need for thorough real-world safety evaluations. METHODS: We performed a retrospective pharmacovigilance study using three major spontaneous reporting systems: the US Food and Drug Administration Adverse Event Reporting System (FAERS), the Japanese Adverse Drug Event Report (JADER), and the Canada Vigilance Adverse Reaction Database (CVARD). We used multiple disproportionality algorithms, including reporting odds ratio, proportional reporting ratio, Bayesian confidence propagation neural network, and multi-item gamma Poisson shrinker for signal detection. Additionally, subgroup and sensitivity, along with logistic regression, were performed. Weibull distribution and log-rank testing were used to assess event timing. RESULTS: A total of 30,689 ADEs were identified in FAERS, spanning 27 system organ classes. Expected signals such as cough, dysphonia, and bronchitis were confirmed. Unexpected events included dyspnea, visual and memory impairment, coronary artery embolism, and asthmatic crisis. Sex-stratified analysis revealed female-specific risks (eg, malaise, bronchitis, alopecia, weight gain) and male-specific risks (eg, dysuria, myocardial infarction). Younger patients (<18 years) were at higher risk for asthmatic crisis, whereas older patients (>65 years) showed a protective effect. The median onset of ADEs was 55 days. Distinctive signals emerged from JADER (eg, pneumonia, liver injury) and CVARD (eg, hemoptysis, hypothyroidism). CONCLUSIONS: This multi-database analysis highlights the need for continuous pharmacovigilance for budesonide/formoterol. The identification of novel ADE signals emphasizes the importance of vigilant monitoring, especially during early treatment, to enhance safety and therapeutic outcomes. |
