Real-world study of adverse events associated with triptan use in migraine treatment based on the U.S. Food and Drug Administration (FDA) adverse event reporting system (FAERS) database

Abstract

Abstract Background Triptans selectively agoniste 5-Hydroxytryptamine(5-HT) receptors and are widely used in the treatment of migraine. Nevertheless, there is a dearth of comprehensive real-world clinical research on the safety of triptans. In light of the growing prevalence of migraine, it is imperative to gain a deeper understanding of the true extent of adverse events (AEs) associated with triptans in the clinical management of migraine. Methods A database query of AEs reported to the U.S. Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) database for triptans was performed using the online platform Open Vigil 2.1. The query spanned the period from 1 January 2018 to 31 December 2023 and extracted all AEs for ‘sumatriptan’, ‘zolmitriptan’, ‘rizatriptan’, and ‘naratriptan’ from the 15–49 years old population and retrospective quantitative analyses. A proportional reporting ratio (PRR), reporting odds ratio (ROR), and Bayesian Confidence Propagation Neural Network (BCPNN) methodology were utilized to contrast AEs across the four triptans. Results A total of 1.272 AEs reports for sumatriptan, 114 for zolmitriptan, 162 for rizatriptan, and 15 for naratriptan were identified. The ratio of females to males was approximately three times higher in all cases, with the highest number of reports originating from the Americas. A review of the FAERS database revealed that nervous system disorders were the primary SOC category for four drugs, with all four drugs exhibiting the AE indicative of reversible cerebral vasoconstriction syndrome, also classified as Nervous system disorders. The most frequently reported AE signal for sumatriptan was dyspnea, which is classified as respiratory, thoracic and mediastinal disorders. The most frequently reported AEs signals for the remaining three drugs were nausea, vomiting and terminal ileitis, all of which are classified as gastrointestinal disorders. Conclusion Analyses have demonstrated that AEs are present in a range of systems, including cardiac, nervous, gastrointestinal, and musculoskeletal disorders. It should be noted, however, that the incidence and signal intensity of these AEs vary depending on the specific drug in question. In clinical practice, the selection of an appropriate drug and the monitoring of AEs should be tailored to the individual patient’s and specific characteristics.
