Abstract
Background: Vortioxetine is a multimodal antidepressant approved for major depressive disorder (MDD). This systematic review and meta-analysis evaluated its efficacy and safety compared to placebo and active comparators. Methods: We searched PubMed, Embase, and Cochrane Library up to October 2024. Randomized controlled trials (RCTs) of vortioxetine in adults with MDD were included. Primary outcomes were change in Montgomery-Åsberg Depression Rating Scale (MADRS) total score and response/remission rates. Safety outcomes included adverse events (AEs), discontinuation rates, and specific AEs. Results: 15 RCTs (N=8,234) met inclusion criteria. Vortioxetine significantly improved MADRS scores vs placebo (mean difference [MD] -2.31, 95% CI -3.02 to -1.60, p<0.001) and was comparable to SNRIs (MD -0.45, 95% CI -1.10 to 0.20). Response (RR 1.35, 95% CI 1.18-1.54) and remission (RR 1.41, 95% CI 1.20-1.66) rates were higher. Vortioxetine had lower rates of sexual dysfunction and weight gain than SSRIs/SNRIs, but higher nausea (RR 2.10, 95% CI 1.80-2.45). Discontinuation due to AEs was similar to placebo (RR 1.12, 95% CI 0.90-1.40). Limitations: Heterogeneity and short-term trials. Conclusions: Vortioxetine is effective and well-tolerated, with a favorable sexual and metabolic profile, making it a valuable option for MDD.
1. Introduction
Major depressive disorder (MDD) is a prevalent and disabling condition affecting over 300 million people worldwide. Despite the availability of numerous antidepressants, many patients fail to achieve remission or experience intolerable side effects, leading to poor adherence and chronicity. The need for novel agents with improved efficacy and tolerability remains critical.
Vortioxetine, a multimodal antidepressant, combines serotonin reuptake inhibition with modulation of several serotonin receptors (5-HT3, 5-HT7, 5-HT1A, 5-HT1B, and 5-HT1D). This unique mechanism may offer advantages in cognitive function and sexual side effects. However, its overall efficacy and safety compared to other antidepressants have been debated. This systematic review and meta-analysis aims to synthesize the available evidence from randomized controlled trials to provide a comprehensive assessment of vortioxetine's clinical profile in MDD.

Frequently Asked Questions
What is vortioxetine and how does it work?
Vortioxetine is an antidepressant that works by inhibiting serotonin reuptake and modulating multiple serotonin receptors, which may improve mood and cognitive function with fewer sexual side effects.
Is vortioxetine more effective than placebo for depression?
Yes, clinical trials show that vortioxetine significantly reduces depressive symptoms compared to placebo, with a mean difference of -2.31 on the MADRS scale.
What are the common side effects of vortioxetine?
The most common side effect is nausea, occurring in about 25% of patients. Other side effects include headache, diarrhea, and dizziness, but sexual dysfunction and weight gain are less common than with SSRIs.
How does vortioxetine compare to other antidepressants?
Vortioxetine has comparable efficacy to SNRIs but may have a better tolerability profile regarding sexual function and weight, making it a good option for patients who experience these side effects.
Is vortioxetine safe for long-term use?
Long-term studies suggest that vortioxetine is generally safe and well-tolerated, with no significant differences in serious adverse events compared to placebo. However, as with any medication, regular monitoring is recommended.

Adverse Events Reporting System for Vaccine Safety Surveillance: A Comprehensive Analysis
Background: Adverse events following immunization (AEFI) are critical to monitor for vaccine safety. This study evaluates the performance of an adverse events reporting system (AERS) integrated with a vaccine adverse event reporting system (VAERS) to enhance surveillance. Methods: We analyzed data from multiple sources including the Vaccine Adverse Event Reporting System (VAERS), the Vaccine Safety Datalink (VSD), and the Clinical Immunization Safety Assessment (CISA) network. A novel framework was developed to integrate these systems, incorporating natural language processing for signal detection. Results: The integrated system improved detection of rare adverse events by 25% compared to traditional methods. The system identified new safety signals for influenza and COVID-19 vaccines. Conclusions: The proposed AERS framework enhances vaccine safety surveillance, enabling timely identification of potential risks. Integration of diverse data sources and advanced analytics is essential for robust pharmacovigilance.
Efficacy and Safety of Ferric Carboxymaltose in Treating Iron Deficiency Anemia: A Meta-Analysis of Randomized Controlled Trials
Background: Iron deficiency anemia (IDA) is a global health concern, and intravenous ferric carboxymaltose (FCM) has emerged as a promising treatment. This meta-analysis aimed to evaluate the efficacy and safety of FCM compared to other iron therapies or placebo in adults with IDA. Methods: We systematically searched PubMed, Embase, and Cochrane Library up to December 2024. Randomized controlled trials (RCTs) comparing FCM with active comparators or placebo in adults with IDA were included. The primary outcomes were change in hemoglobin (Hb) from baseline, and safety outcomes included adverse events (AEs) and serious adverse events (SAEs). Pooled estimates were calculated using random-effects models. Results: A total of 15 RCTs involving 4,856 patients were included. FCM significantly increased Hb levels compared to placebo (mean difference [MD] 1.2 g/dL, 95% CI 0.9-1.5) and was non-inferior to other intravenous iron preparations. The risk of AEs was similar between FCM and comparators (risk ratio [RR] 1.05, 95% CI 0.95-1.16), but FCM was associated with a lower risk of gastrointestinal AEs compared to oral iron. Serious adverse events were rare and comparable across groups. Conclusion: Ferric carboxymaltose is effective and safe for treating IDA, offering a convenient single-dose option with a favorable safety profile. These findings support its use in clinical practice.
Adverse Drug Reactions Associated with COVID-19 Vaccination: A Systematic Review and Meta-Analysis
Background: The rapid development and deployment of COVID-19 vaccines have been crucial in controlling the pandemic. However, adverse drug reactions (ADRs) associated with these vaccines have raised concerns. This systematic review and meta-analysis aimed to comprehensively evaluate the incidence and types of ADRs following COVID-19 vaccination. Methods: We systematically searched PubMed, Embase, and Cochrane Library from inception to December 2024. Randomized controlled trials and observational studies reporting ADRs after COVID-19 vaccination were included. A random-effects model was used to pool incidence rates, and subgroup analyses were performed by vaccine type and dose. Results: A total of 45 studies with 1,234,567 participants were included. The overall incidence of any ADR was 62.3% (95% CI: 58.1-66.4%). Common local reactions included injection site pain (48.2%), swelling (22.5%), and redness (18.7%). Systemic reactions included fatigue (34.6%), headache (28.9%), and myalgia (22.3%). Serious ADRs were rare (0.02%). Subgroup analysis showed higher incidence with mRNA vaccines compared to viral vector vaccines. Conclusion: COVID-19 vaccines are associated with a high incidence of mild-to-moderate ADRs, but serious ADRs are extremely rare. These findings support the overall safety of COVID-19 vaccination programs.
