Acute Efficacy and Safety of Escitalopram Versus Desvenlafaxine and Vortioxetine in the Treatment of Depression With Cognitive Complaint: A Rater-Blinded Randomized Comparative Study

Unveiling potential adverse events associated with escitalopram oxalate: A real-world analysis based FDA adverse event reporting system database

OBJECTIVE

The study aimed to conduct a multidimensional evaluation of potential adverse events (AEs) of escitalopram oxalate based on the FDA adverse event reporting system (FAERS) database.

METHODS

This study utilized the reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian confidence propagation neural network (BCPNN), and multi-item gamma-poisson shrinker (MGPS) to mine and analyze data from the FAERS database from the first quarter of 2004 to the second quarter of 2023.

RESULTS

There was a total of 19,854 AE reports related to escitalopram oxalate, extracting 625 preferred terms (PTs), and covering 27 system organ classes (SOCs). The results showed that the number of reports by females was significantly higher than males, accounting for 57.68%. The reporting number was higher in 2018 and 2019, accounting for 9.50% and 10.18% of the total reports, respectively. The main reporters were consumers and other health professionals, accounting for 26.99% and 26.75% respectively. The majority of the reports were primarily from the United States. Newly emerging AE signals such as intentional overdose (n = 691, ROR 8.51, PRR 8.45, IC 3.05, Empirical Bayesian Geometric Mean (EBGM) 8.35), suicide attempt (n = 665, ROR 8.58, PRR 8.52, IC 3.06, EBGM 8.42), serum serotonin (n = 5, ROR 1044.78, PRR 1044.71, IC 2.56, EBGM 392.39), anti-actin antibody positive (n = 5, ROR 626.87, PRR 626.83, IC 2.56, EBGM 313.91), among others, were not mentioned in the drug's label.

CONCLUSION

While escitalopram oxalate has clear benefits in the treatment of depression and other mental health disorders, the presence of AEs also suggests risks associated with its use. Particularly concerning are risks of suicide and changes in serum serotonin levels.

A Randomized Controlled Trial Comparing Efficacy and Safety of Antidepressant Monotherapy

BACKGROUND AND OBJECTIVES

The majority of mainstream antidepressants lack the promise of complete amelioration of symptoms. Other pitfalls include the latency period and side effects. These issues prompted investigations concerning the various roles of serotonin (5-HT) neurotransmissions in the etiology of depression. In this study, each study participant received vilazodone, vortioxetine, and escitalopram monotherapy for major depressive disorder (MDD) for 16 weeks. After that, the subject's scores on the Hamilton Depression Rating Scale (HDRS)-17 item version and the Montgomery Åsberg Depression Rating Scale (MADRS) were evaluated. In the study population, we kept track of the incidence of adverse events.

METHODS

Ninety-six patients with MDD participated in this open-label, randomized, three-arm study. Participants were allotted into three groups according to a 1:1:1 ratio and given vilazodone (20-40 mg/day), vortioxetine (5-20 mg/day), or escitalopram (10-20 mg/day) for 16 weeks. Vortioxetine and vilazodone are test medications, with escitalopram serving as the control. After the baseline visit, follow-up appointments were scheduled every four weeks. Per-protocol (PP) and intent-to-treat (ITT) populations served as means for efficacy and safety evaluations, respectively. We prospectively registered this research in the Clinical Trial Registry, India (CTRI) (2022/07/043808).

RESULTS

Out of the 134 patients we screened, 109 (81.34%) were eligible. Ninety-six (88.07%) of them completed the 16-week trial. In the PP population (n = 96), we analyzed efficacy. They had a mean age of 46.3 ± 6.2 years. At baseline, each group's median HDRS score was 30.0 (p = 0.964). Following 16 weeks of antidepressant therapy, these scores dropped to 15.0, 14.0, and 13.0 (p = 0.002). Baseline MADRS scores for all groups were 36.0 (p = 0.741). They had corresponding values of 20.0, 18.0, and 17.0 at 16 weeks (p < 0.001). Regarding both efficacy endpoints, the post-hoc analysis with the Bonferroni correction demonstrated statistically significant differences (p < 0.001). We performed the safety assessments within our ITT population (n = 109). Ninety-six adverse events were recorded. Nonetheless, none of them seemed serious. Still, five participants opted out because of their side effects. Vomiting and nausea were the most frequent side effects.

CONCLUSION

Compared to escitalopram and vilazodone, vortioxetine demonstrated a statistically significant reduction in HDRS and MADRS scores. It also had fewer and milder side effects. We recommend conducting studies involving a broader population to investigate the antidepressant effects of these medications further.

The Role of Vortioxetine in the Treatment of Depressive Symptoms in General Hospital Psychiatry: A Case-Series and PRISMA-Compliant Systematic Review of the Literature

Depressive symptoms are a customary finding in hospitalized patients, particularly those who are undergoing long hospitalizations, underwent major surgical procedures or suffer from high levels of multimorbidity and frailty. The patients included in this case series shared high degrees of frailty-complexity and were evaluated within the ordinary consultation and liaison psychiatry service of the University Hospital in Pisa, Italy, from September 2021 to June 2023. Patients were administered at least one follow-up evaluation after a week and before discharge. To relate this case series to the extant literature, a comprehensive systematic review of vortioxetine safety and efficacy was performed. None of the six patients included developed serious safety issues, but one patient complained of mild-to-moderate nausea for some days after the vortioxetine introduction. Five out of six patients exhibited at least a slight clinical benefit as measured by the clinical global impression scale. Of the 858 entries screened via Scopus and Medline/PubMed, a total of 134 papers were included in our review. The present case series provides preliminary evidence for vortioxetine's safety in this healthcare domain. The literature reviewed in this paper seems to endorse a promising safety profile and a very peculiar efficacy niche for vortioxetine in consultation and liaison psychiatry.

[Impact of vortioxetine on sexual function compared to other antidepressants]

OBJECTIVE

To analyze the impact of the antidepressant vortioxetine on sexual function, compared to selective serotonin reuptake inhibitors (SSRIs) and mixed selective serotonin and norepinephrine reuptake inhibitors (IRSN or Dual) in patients with depression.

MATERIAL AND METHODS

Analytical, observational, longitudinal and prospective study, which included men and women over 18years of age, with depressive disorder and sexual activity with a partner, separating them into two groups: (i)study, starting treatment with vortioxetine; (2)control, maintaining treatment with SSRIs or Duals. Three visits were made: inclusion, follow-up at 4weeks and final 3months from inclusion. The total follow-up period was 3months.

RESULTS

A total of 87 patients were included (mean age 46.85years). At the end of the study, significant differences (SD) were found in the mean value of the sum of the scores of the evaluative domains of the sexual response of the Women's Sexual Function Questionnaire (FSM-2) between the study group and the control (22.42±4.39 and 16.13±7.76, respectively), with a lower risk of sexual dysfunction in women treated with vortioxetine. Also, lower risk of sexual dysfunction in these same women in the domains of desire, lubrication, orgasm, sexual frequency and sexual satisfaction. These differences were not found when assessing male sexual function.

CONCLUSIONS

Women treated with vortioxetine presented better sexual function than those treated with SSRIs or Duals and a lower risk of sexual dysfunction.

Efficacy and tolerability of desvenlafaxine in the real-world treatment of patients with major depression: a narrative review and an expert opinion paper

INTRODUCTION

Major depressive disorder (MDD) is a common severe mental disorder, requiring a tailored and integrated treatment. Several approaches are available including different classes of antidepressants various psychotherapeutic approaches, and psychosocial interventions. The treatment plan for each patient with MDD should be differentiated on the basis of several clinical, personal, and contextual factors.

AREAS COVERED

Desvenlafaxine - a serotonine-noradrenergic reuptake inhibitor (SNRI) antidepressant - has been approved in the United States in 2008 for the treatment of MDD in adults, and has been recently rediscovered by clinicians due to its good side-effect profile and its clinical effectiveness. A narrative review on efficacy, tolerability and use of desvenlafaxine in clinical practice was carried out. The keywords: 'major depression', 'depression,' 'desvenlafaxine,' 'efficacy,' 'clinical efficacy,' 'side effects', 'tolerability,' 'elderly patients', 'consultation-liaison', 'menopausal', 'young people', 'adolescent' were entered in PubMed, ISI Web of Knowledge, Scopus and Medline. No time limit was fixed, the search strategy was implemented on May 10, 2023.

EXPERT OPINION

Desvenlafaxine should be listed among the optimal treatment strategies for managing people with MDD, whose main strengths are: 1) ease of dosing; 2) favorable safety and tolerability profile, 3) absence of sexual dysfunctions, weight gain and low rate of discontinuation symptoms; 4) low risk of drug-drug interactions.

An Interim Analysis of a Randomized, Open-Label Study of Vilazodone, Escitalopram, or Vortioxetine for Major Depressive Disorder

INTRODUCTION

The troubling issues of conventional antidepressants are inadequate disease remission and potential adverse effects. There is a dearth of research findings comparing vilazodone, escitalopram, and vortioxetine. The objective of this analysis is to determinechanges in the Hamilton Depression Rating Scale (HDRS) and Montgomery-Åsberg Depression Rating Scale (MADRS) scoresand the incidence of adverse events at 12 weeks.

METHODS

This is an exploratory interim analysis of a randomized, three-arm, open-label ongoing study. The participants were randomly assigned in a 1:1:1 ratio to receive either vilazodone (20-40 mg/d), escitalopram (10-20 mg/d), or vortioxetine (5-20 mg/d). Efficacy and safety assessments were done at baseline, four weeks, eight weeks, and 12 weeks.

RESULTS

Forty-nine(69%) of the 71 enrolled participants (mean age 43.9±12.2 years; 37 men (52%)) completed the 12-week follow-up. At baseline, the three groups' median HDRS scores were 30.0, 29.5, and 29.0 (p=0.76), respectively, and at 12 weeks, they amounted to 19.5, 19.5, and 18.0 (p=0.18), respectively. At baseline, group-wise median MADRS scores were 36, 36, and 36, respectively (p=0.79); at 12 weeks, they were 24, 24, and 23, respectively (p=0.03). In the post-hoc analysis, the inter-group comparison of the change in HDRS (p = 0.02) and MADRS (p = 0.06) scores from baseline did not reach statistical significance. No participants experienced serious adverse events.

CONCLUSION

In this initial assessment of a continuing study, vortioxetine exhibited a clinically (not statistically) significant drop in HDRS and MADRS scores, compared to vilazodone and escitalopram. The antidepressant effects need to be investigated further.

Agomelatine, Ketamine and Vortioxetine Attenuate Energy Cell Metabolism-In Vitro Study

This determination of the mitochondrial effect of pharmacologically different antidepressants (agomelatine, ketamine and vortioxetine) was evaluated and quantified in vitro in pig brain-isolated mitochondria. We measured the activity of mitochondrial complexes, citrate synthase, malate dehydrogenase and monoamine oxidase, and the mitochondrial respiratory rate. Total hydrogen peroxide production and ATP production were assayed. The most potent inhibitor of all mitochondrial complexes and complex I-linked respiration was vortioxetine. Agomelatine and ketamine inhibited only complex IV activity. None of the drugs affected complex II-linked respiration, citrate synthase or malate dehydrogenase activity. Hydrogen peroxide production was mildly increased by agomelatine, which might contribute to increased oxidative damage and adverse effects at high drug concentrations. Vortioxetine significantly reduced hydrogen peroxide concentrations, which might suggest antioxidant mechanism activation. All tested antidepressants were partial MAO-A inhibitors, which might contribute to their antidepressant effect. We observed vortioxetine-induced MAO-B inhibition, which might be linked to decreased hydrogen peroxide formation and contribute to its procognitive and neuroprotective effects. Mitochondrial dysfunction could be linked to the adverse effects of vortioxetine, as vortioxetine is the most potent inhibitor of mitochondrial complexes and complex I-linked respiration. Clarifying the molecular interaction between drugs and mitochondria is important to fully understand their mechanism of action and the connection between their mechanisms and their therapeutic and/or adverse effects.
