Post-marketing safety evaluation of Vortioxetine: A decade-long pharmacovigilance study based on the FAERS database

This study evaluated adverse events (AEs) associated with Vortioxetine by analyzing extensive data from the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS). We collected data from the FAERS database spanning ten years, from the first quarter of 2014 to the second quarter of 2024, focusing on drug-related AEs involving Vortioxetine. A comprehensive analysis was performed using multiple signal detection methods, including reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian Confidence Propagation Neural Network (BCPNN), and Multi-item Gamma Poisson Shrinker (MGPS). Among 13,116 reports where Vortioxetine was identified as the primary suspect drug, AEs were categorized into 27 system organ classes (SOCs) and 146 preferred terms (PTs). The results highlighted significant signals for common AEs, such as psychiatric disorders, gastrointestinal disorders, and nervous system disorders. Notably, feeling guilty exhibited the strongest signal strength; however, its clinical relevance requires cautious interpretation. Additionally, the study identified novel signals not listed in the drug label but potentially of clinical value, such as hyperarousal and alcoholic, which were significantly associated with Vortioxetine. Of particular note, AEs related to sexual dysfunction were the most diverse, while suicidal ideation was the most frequently reported. The study also uncovered rare but noteworthy signals, including hallucination and olfactory disorders, dermatillomania, and bruxism, which warrant further attention. In conclusion, while Vortioxetine demonstrates multifaceted benefits in alleviating symptoms of depression, its clinical use requires a comprehensive evaluation of potential risks. Developing safe and rational treatment strategies is essential to optimize therapeutic outcomes.
