| アブストラクト | Background Medications exhibiting serotonergic properties, such as selective serotonin reuptake inhibitors (SSRI) antidepressants, opioids, and other antidepressants can induce as adverse reaction serotonin syndrome, a rare but potentially life-threatening adverse event. Aim This study aims to investigate the risks of serotonin syndrome among different SSRIs and assess the influence of drug-drug interactions with other medications. Methods We analyzed the suspected adverse events in the US Food and Drug Administration Adverse Event Reporting System (FAERS) database. Results We identified 13,312 reports of serotonin syndrome, 52% of which involved SSRIs (n=6,921), with ROR of 24.19. Among the safety reports involving SSRIs, 4,851 cases reported at least one severe outcome. All active substances of the SSRI group were associated with serotonin syndrome, sertraline and fluoxetine had the most reports, while fluvoxamine had the highest ROR and risk compared to all other SSRIs (ROR: 2.66, 95% confidence interval: 2.33-3.05). The combinations of SSRIs with other drugs with the most reported cases were SSRIs-antidepressants (n=2395) and SSRIs-opioids (n=2252). The combinations of SSRIs with SNRIs (ROR 25.42, omega 0.11) and 'other antidepressants' (ROR 22.74, omega 0.16) were associated with a signal for serotonin syndrome. The combination SSRIs-opioids was associated with a safety signal, particularly those with higher risk for serotonin syndrome, like tramadol and fentanyl (ROR 41.95, omega 1.25). Conclusion Close monitoring for symptoms of serotonin syndrome should be considered in patients with depression with a combination of antidepressants, and in those on SSRIs who also require linezolid, MAO inhibitors or high-risk opioids, like tramadol, or fentanyl. |
