RESUMO
INTRODUCTION: Vortioxetine is an antidepressant with a multimodal mechanism of action. It is used as a treatment option for patients with major depressive episodes. There have only been two previously reported non-fatal overdoses of vortioxetine; neither of these were analytically confirmed There has also been one case of serotonin syndrome potentially related to vortioxetine and two deaths where vortioxetine was detected. We report here a non-fatal analytically confirmed case of vortioxetine overdose. CASE REPORT: A 32-year-old male presented to the emergency department (ED) 12-13 h after oral ingestion of 1,260 mg of vortioxetine and 350 mg of diazepam. A family member reported that he had been drowsy after the overdose, but his level of consciousness and observations (heart rate, blood pressure and temperature) were normal on review by the pre-hospital emergency services and on arrival to the ED. During a period of observation, he did not develop any features of serotonin syndrome or any other significant toxicity. Toxicological analysis of a blood sample taken in the ED detected vortioxetine (plasma concentration 457 ng/mL 10 h after ingestion) and sub-therapeutic concentrations of diazepam and pregabalin. DISCUSSION: Despite having a plasma vortioxetine concentration nearly 15-times therapeutic vortioxetine concentrations, this patient did not develop any significant toxicity. In particular he did not develop any clinical or biochemical features of serotonin toxicity that would be expected with this class of antidepressant. Additional reporting of analytically confirmed vortioxetine overdoses will allow clinicians and licensing authorities to further understand the safety of this medication in overdose.
RESUMO
OBJECTIVE: Vortioxetine has demonstrated safety and efficacy in improving symptoms of major depressive disorder (MDD), including overall functioning in real-world settings. This is the first study in a real-life clinical setting in India to evaluate effectiveness and safety of vortioxetine in patients with MDD. METHODS: This interventional, open-label study consisted of a 12-week treatment period with flexible doses of vortioxetine (5-20 mg/day) in adult patients (aged 18-65 years) with a confirmed MDD diagnosis. Effectiveness outcomes included change from baseline to week 12 in Patient Health Questionnaire-9 (PHQ-9) and Clinical Global Impression-Severity (CGI-S) scores, along with CGI-Improvement (CGI-I) scores at week 12, using a mixed model for repeated measures. Adverse events (AEs) were recorded for safety outcome assessments. RESULTS: Of 395 patients who received vortioxetine, 42.3% were women mean age 38.9 years; 322 patients completed the study. Significant improvement in depressive symptoms was observed in change from baseline to week 12 least squares (LS) mean (SE) PHQ-9 total score (-9.36 [0.276]; p<.0001) and CGI-S score (-2.14 [0.065]; p<.0001). LS mean (SE) CGI-I score showed significant improvement at week 12 (1.93 [0.067]; p<.0001). Subgroup analysis across age, sex, disease severity, and body mass index showed significant improvements in depression symptoms and severity. A total of 35.4% (n = 140) of patients experienced treatment-emergent AEs (mostly mild-moderate); nausea and pruritus were the most frequent (6.6%, n = 26 each). CONCLUSION: Safety and effectiveness of vortioxetine in improving symptoms of MDD over a 12-week period was demonstrated in a real-life clinical setting in India. CLINICAL TRIAL REGISTRATION INFORMATION: Open-label, flexible-dose study of vortioxetine in patients with major depressive disorder in India; Clinical Trials.gov ID: NCT04288895; https://www.clinicaltrials.gov/study/NCT04288895.
RESUMO
OBJECTIVE: Weight gain is a common side effect of antidepressive treatment, causing distress among patients and caretakers as it can lead to treatment discontinuation and complications such as diabetes type II and cardiovascular disease. Vortioxetine is one of the newer antidepressants and the pharmacodynamics differ from the selective serotonin reuptake inhibitors. It is marketed as being weight neutral; however, there is little evidence as to why. In recent years, there has been an increased focus on the faecal microbiota and its impact on body weight and mental and physical health. In the current work, we examine the effect of vortioxetine on weight gain and faecal microbiota composition. METHODS: Forty male C57BL/6NTac mice were primed for 8 weeks with a high-fat diet (Hfd) or control diet (Cd), followed by a 4-week period on the same diet and additional +/- vortioxetine 10 mg/kg/daily. RESULTS: Vortioxetine reduced Hfd-induced weight gain (Hfd + V: 8.2%, Hfd - V: 12.7%; p = 0.0374) but did not affect weight gain of the control group (Cd + V: 7.54%, Cd - V: 7.56%; p = 0.4944). Significant differences in faecal microbiota were observed in mice who received vortioxetine. CONCLUSION: Vortioxetine caused significant changes to the faecal microbiota composition and appeared to limit Hfd-induced weight gain.
RESUMO
Background: The multinational, open-label COMPLETE study (NCT03835715) investigated the effectiveness of vortioxetine in alleviating emotional blunting in patients with major depressive disorder (MDD) experiencing inadequate response and emotional blunting while being treated with a selective serotonin reuptake inhibitor (SSRI) or serotonin-noradrenaline reuptake inhibitor (SNRI). This paper presents results for the subgroup of patients enrolled in Spain. Methods: Patients with MDD (n = 67) experiencing partial response and emotional blunting during monotherapy with an SSRI or SNRI were switched to vortioxetine (10-20 mg/day) for 8 weeks. The primary study outcome was emotional blunting, assessed by the Oxford Depression Questionnaire (ODQ). Results: After 8 weeks of vortioxetine, the mean (SE) change in ODQ total score from baseline was -26.0 (2.9) (P < 0.001). Respective changes in Montgomery-Åsberg Depression Rating Scale (MADRS), Motivation and Energy Inventory, Digit Symbol Substitution Test, and Sheehan Disability Scale (SDS) total scores were -14.9 (0.8), +34.2 (4.5), +6.3 (1.6), and â9.0 (1.3) (all P < 0.001 vs baseline). At week 8, 70.4% of patients no longer reported emotional blunting and 53.7% had achieved remission from their depressive symptoms (defined as a MADRS total score ≤10). Mediation analysis showed 77.1% of the change in SDS total score to be a direct effect of the improvement in ODQ total score after switching to vortioxetine. Adverse events were reported by 35 patients (52.2%), most commonly nausea (14 patients, 20.9%). At week 8, 33/54 patients (61.1%) were receiving vortioxetine 20 mg/day. Conclusion: In this study investigating the effectiveness of vortioxetine in Spanish patients with MDD who experienced inadequate response and emotional blunting on SSRI/SNRI monotherapy, significant improvements in emotional blunting, core depressive symptoms (including anhedonia), sleep duration, motivation and energy, cognitive performance, and overall patient functioning were observed during the 8 weeks of treatment. Two-thirds of patients no longer reported emotional blunting and over half were in remission from their depressive symptoms at week 8.
RESUMO
BACKGROUND: Several studies provide clear evidence that exposure to various infections during pregnancy are linked with an increased risk for schizophrenia. In preclinical studies, administration of polyinosinic-polycytidylic acid (Poly I:C) in pregnant rodents can induce maternal immune activation leading to impairments in brain function in the offspring. OBJECTIVES: The aim of this study was to investigate the effect of vortioxetine, a multimodal selective serotonin reuptake inhibitor (SSRI), in the pathophysiology of Poly I:C-induced schizophrenia-like model in rats. METHODS: For this purpose, Poly I:C (8 mg/kg, ip) was injected into pregnant animals 14 days after mating, and tail blood was taken for determination of IL-6 levels after 2 h. At postnatal days 83-86, behavioral tests were performed. RESULTS: Our results revealed that Poly I:C caused impairments in prepulse inhibition, novel object recognition, social interaction, and open-field tests. Chronic administration of vortioxetine (2.5, 5, and 10 mg/kg, ip, postnatal days 69-83) caused significant improvements in these deficits. CONCLUSION: Overall, our findings indicate that vortioxetine may provide new therapeutic approaches for the treatment of schizophrenia. We think that increased serotonergic activity in frontal brain regions may provide the ameliorative effect of vortioxetine, especially on negative and cognitive symptoms. Therefore, it will be useful to determine the efficacy of vortioxetine with combined drugs with further studies.
RESUMO
Introduction and objective: Several studies revealed the therapeutic potential of vortioxetine (Vo) for pain. In this context, we aimed to evaluate the efficacy of Vo as a safe and tolerable novel pharmacologic agent in treating neuropathic pain (NP) in patients with major depressive disorder (MDD). Materials and methods: The population of this cross-sectional prospective study consisted of all consecutive patients who were newly diagnosed with MDD by a neurology doctor at a psychiatric clinic and had NP for at least 6 months. All patients included in the sample were started on Vo treatment at 10 mg/day. They were assessed with Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Self-Reported Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS), Douleur Neuropathique 4 Questions (DN4), Montreal Cognitive Assessment (MoCA), and Neuropathic Pain Impact on Quality of Life (NePIQoL) at the beginning of treatment and during the follow visits conducted at the end of the first, second and third months of the treatment. During these follow-up visits, patients were also queried about any side effects of Vo. Results: The mean age of 50 patients included in the sample, 76% of whom were female, was 45.8 ± 11.2 years. There was a significant reduction in patients' NP complaints based on DN4 and S-LANNS, the subscales of NePIQoL, and significant improvement in MoCA. There was a significant reduction in patients' NP complaints based on DN4 and S-LANNS scores and a significant improvement in scores of the subscales of NePIQoL and MoCA. Conclusion: The study's findings indicate that Vo, with its multiple mechanisms of action, can effectively treat NP independently of its mood-stabilizing effect. Future indication studies for Vo are needed to establish Vo's efficacy in treating NP.
RESUMO
BACKGROUND: Inflammasome overactivation, multiprotein complexes that trigger inflammatory responses, plays a critical role in Major Depressive Disorder (MDD) pathogenesis and treatment responses. Indeed, different antidepressants alleviate depression-related behaviours by specifically counteracting the NLRP3 inflammasome signalling pathway. The immunomodulatory effects of vortioxetine (VTX), a multimodal antidepressant with cognitive benefits, were recently revealed to counter memory impairment induced by a peripheral lipopolysaccharide (LPS) injection 24 hours (h) postchallenge. METHODS: The potential link between VTX and NLRP3, along with other inflammasomes, remains unexplored. Hence, adult C57BL/6J male mice (n = 73) were fed with a standard or VTX-enriched diet (600 mg/kg of food, 28 days), injected with LPS (830 µg/kg) or saline, and sacrificed 6/24 h post-LPS. At these time-points, transcriptional effects of LPS and VTX's on NLRP3, NLRP1, NLRC4, AIM2 (inflammasomes), ASC and CASP1 (related subunits) and NEK7 mediator (NLRP3 regulator) were assessed in dorsal and ventral hippocampal subregions, frontal-prefrontal cortex and hypothalamus, brain regions serving behavioural-cognitive functions impaired in MDD. RESULTS: Varied expression patterns of inflammasomes were revealed, with long-term NLRP3 and ASC transcriptional changes observed in response to LPS. It was discovered that VTX counteracted the LPS-mediated NLRP3 and ASC upregulation in memory-related brain areas like the dorsal hippocampus at 24 h time-point, potentially via regulating NEK7 expression. No VTX-mediated transcriptional effects were observed on other inflammasomes, reinforcing a potentially specific modulation on the NLRP3 inflammasome signalling pathway. CONCLUSION: Thus, a novel VTX's molecular mechanism in modulating the NLRP3 inflammasome in a time- and area-specific manner in the brain was highlighted, with significant clinical implications in treating depression and cognitive impairments.
.RESUMO
Background and objectives The quality of life declines with the growing severity of major depressive disorder (MDD). In depressed people, medication adherence and the quality of life are mutually corrosive. These concerns spurred the investigation of relationships between treatment outcomes and adherence levels. Limited studies are looking at how vortioxetine, escitalopram, and vilazodone affect these parameters. We aimed to detect how the Short Form-36 (SF-36) had changed 16 weeks after the baseline. The connection between treatment results (as expressed by the Hamilton Depression Rating Scale or HDRS) and medication adherence (as reflected by the Morisky Medication Adherence Scale-8 or MMAS-8) was also explored. Methods An open-label, randomized, three-arm trial with 96 MDD patients was conducted. For 16 weeks, the participants were put into three groups per a 1:1:1 ratio and administered tablets of vilazodone (20-40 mg/day), escitalopram (10-20 mg/day), or vortioxetine (5-20 mg/day). There were two test drugs: vilazodone and vortioxetine; the control was escitalopram. Four weeks apart, follow-up appointments were set after the baseline visit. The HDRS, mental and physical components of SF-36, and MMAS-8 scores were evaluated in the per-protocol (PP) population. Reduced HDRS scores were indicative of improved depression symptoms. Higher MMAS-8 and SF-36 scores indicated high drug adherence and enhanced quality of life. Our analysis used the Kruskal-Wallis test, the Bonferroni correction, and the Sankey diagram. In the Clinical Trial Registry-India (CTRI), we recorded this study prospectively (2022/07/043808). Results One hundred nine (81.34%) of the 134 individuals we examined were eligible. The PP population consisted of 96 (88.07%) of them who wrapped up the 16-week study. The mean age of the group was 46.3 ± 6.2 years. For each of the three groups, the SF-36 physical component scores revealed a median difference of 24.5 (23.8-26.0), 24.0 (22.8-25.3), and 27.0 (25.0-29.0) (p = 0.001). Accordingly, the mental components of their SF-36 scores showed a median difference of 32.0 (31.0-33.3), 31.0 (29.8-34.3), and 36.0 (33.0-38.0) (p = 0.001). A median difference of -15.0 (-16.0 to -14.0), -16.0 (-17.0 to -15.0), and -16.0 (-17.0 to -15.8) was observed in the HDRS scores after 16 weeks, with respect to the baseline (p < 0.001). The median MMAS-8 scores at 16 weeks were 6.0 (6.0-7.0), 6.8 (6.0-7.0), and 7.5 (6.5-8.0) (p = 0.031). The Sankey diagram illustrated the connection between better treatment results, increased medication compliance, and decreased symptoms of depression. Conclusion In comparison to vilazodone and escitalopram, vortioxetine demonstrated a statistically significant decrease in HDRS scores and an improvement in the physical and mental component scores of the SF-36. Clinical improvements were evident in the individuals' drug adherence levels. Larger-scale studies are advised to investigate the effects of these medications on the quality of life, medication adherence, and treatment outcomes.
RESUMO
BACKGROUND: It is previously reported that the Montgomery-Åsberg Depression Rating Scale (MADRS) anhedonia factor score is correlated with scales assessing function in patients with major depressive disorder (MDD). METHODS: This was an analysis of a database including 5 long-term, extension studies of prior controlled trials, which evaluated the effects of open-label, maintenance treatment with vortioxetine (5-20 mg/day over 1-year) in adults with MDD. We assessed the association of changes in MADRS anhedonia factor scores with changes in the Clinical Global Impression of Severity (CGI-S), Sheehan Disability scale (SDS), and the SF-36. A minimal clinically important change (MCIC) for MADRS anhedonia factor scores was determined using the CGI-S as anchor. RESULTS: In patients who had completed the prior controlled studies, MADRS anhedonia factor scores continued to improve over 1-year of maintenance treatment (mean ± SE change from baseline of -6.2 ± 0.2 at Month 12). Change in MADRS anhedonia factors score correlated with change in CGI-S (Week 4, r = 0.71), SDS (Week 24 r = 0.60) and SF-36 domains (Week 24 r = -0.19 to -0.61) scores. Using a 1 level improvement on CGI-S as anchor, the MCIC for MADRS anhedonia factor scores versus baseline were - 4.6 at Week 4, -5.5 at Week 24, and - 5.3 at Week 52. LIMITATIONS: Neither the MADRS scale, nor the primary studies, were specifically designed to assess anhedonia. CONCLUSIONS: These open-label data suggest that patients treated with vortioxetine continued to show clinically relevant improvements in their anhedonia over 1-year of maintenance therapy. Improvements in anhedonia correlated with improvements in measures of functioning and quality of life.

BACKGROUND: Data demonstrating the real-world, long-term effectiveness of vortioxetine in elderly patients with major depressive disorder (MDD) are clinically useful to confirm findings from randomized trials. METHODS: RELIEVE was a multinational, 24-week, observational, prospective study in outpatients with MDD initiating vortioxetine treatment in routine care settings (NCT03555136). Here, we report data from a subgroup of 130 patients aged ⩾ 65 years. The primary study outcome was changed from baseline in patient functioning assessed using the Sheehan Disability Scale (SDS). Other clinical outcomes included depression severity (Patient Health Questionnaire-9 [PHQ-9] and Clinical Global Impressions-Severity [CGI-S]), cognitive performance (Digit Symbol Substitution Test [DSST]) and symptoms (Perceived Deficits Questionnaire - Depression-5 item [PDQ-D-5]), and health-related quality of life (HRQoL) (EuroQoL 5 Dimensions 5 Levels [EQ-5D-5L]). RESULTS: Clinically meaningful and statistically significant improvements in patient functioning, depressive symptoms, cognitive function, and HRQoL were observed at week 24. Least squares mean SDS, PHQ-9, CGI-S, PDQ-D-5, DSST, and EQ-5D-5L scores improved from baseline by 6.5, 5.7, 1.2, 3.2, 4.4, and 0.11 points, respectively (p < 0.01 for all). Adverse events were observed in 23.1% of patients. CONCLUSIONS: Consistent with previous clinical studies of vortioxetine, this study supports the effectiveness and safety of vortioxetine in treating elderly patients with MDD in a real-world setting over a 6-month period. Patients showed clinically relevant and sustained improvements in psychosocial functioning, depressive symptoms, and cognitive function after receiving vortioxetine, which was generally well tolerated. Main study limitations include the open-label study design and lack of a placebo or comparator group.

AIM: Major depressive disorder (MDD) is a prevalent psychiatric condition and vortioxetine offers promising antidepressant effects due to its unique pharmacological profile. However, the dose-response relationships of vortioxetine for MDD is not well established. We aimed to conduct dose-response meta-analyses to fill this gap. METHODS: We systematically searched multiple electronic databases for randomized controlled trials of vortioxetine for MDD, with the last search conducted on 08 February, 2024. The dose-response relationship was evaluated using a one-stage random-effects dose-response meta-analysis with restricted cubic spline model. The primary outcome was efficacy (mean change in depression scale score), with secondary outcomes including response, dropout for any reasons (acceptability), dropout for adverse events (tolerability), and any adverse events (safety). RESULTS: The dose-response meta-analysis comprised 16 studies, with 4,294 participants allocated to the vortioxetine group and 2,299 participants allocated to the placebo group. The estimated 50% effective dose was 4.37 mg/day, and the near-maximal effective dose (95% effective dose) was 17.93 mg/day. Visual inspection of the dose-efficacy curve suggests that a plateau possibly had not been reached yet at 20 mg/day. Acceptability, tolerability and safety decreased as the dose increased. Subgroup analysis indicated that no significant differences were observed in acceptability, tolerability and safety among the dosage groups. CONCLUSIONS: Vortioxetine may potentially provide additional therapeutic benefits when exceeding the current licensed dosage without significantly impacting safety. Conducting clinical trials exceeding the current approved dosage appears necessary to fully comprehend its efficacy and risk.
RESUMO
BACKGROUND: Age at first onset of depression as a clinical factor affecting cognitive improvement in late life depression was investigated. METHODS: This is a secondary analysis of an eight-week randomized controlled trial involving 452 elderly patients treated by vortioxetine, duloxetine or placebo (1:1:1). Patients were subcategorized into early-onset (LLD-EO) and late-onset (LLD-LO) groups divided by onset age of 50. Cognitive performance was assessed by composite score of Digit Symbol Substitution Test (DSST) and the Rey Auditory Verbal Learning Test (RAVLT) tasks, while depressive symptoms were assessed by Montgomery-Åsberg Depression Rating Scale (MADRS). RESULTS: Vortioxetine and duloxetine exhibited advantages versus placebo in improving cognitive performance in the LLD-LO group, yet not in the LLD-EO group after eight weeks. Patients in the LLD-EO group showed overall advantage to placebo in depressive symptoms before endpoint (week 8) of treatment, while patients in the LLO-LO group showed no advantage until endpoint. Path analysis suggested a direct effect of vortioxetine (B = 0.656, p = .036) and duloxetine (B = 0.726, p = .028) on improving cognition in the LLD-LO group, yet in all-patients treated set both medications improved cognition indirectly through changes of depressive symptoms. LIMITATION: Reliability of clinical history could raise caution as it was collected by subjective recall of patients. CONCLUSION: Age at first onset might affect cognitive improvement as well as change in depressive symptoms and its mediation towards cognitive improvement in late life depression treated with vortioxetine and duloxetine.

Background: We present a case report on the efficacy of the short-term application of vortioxetine in managing winter depression in patients with seasonal bipolar disorder (BP). Standard treatment strategies for BP may not adequately address seasonal depressive symptoms during winter in patients with seasonal BP patterns. Depressive symptoms during winter may be linked to seasonal changes in serotonin transporter binding, such as a decrease in synaptic serotonin levels, necessitating alternative approaches. Although antidepressants, including vortioxetine, are effective in treating seasonal monopolar depression, their efficacy and safety in treating depression in patients with seasonal BP patterns remain unclear. Case Presentation: This case report focuses on a 44-year-old male patient diagnosed with seasonal BP who had recurrent depressive episodes, specifically during winter. Notably, the patient had a significant decrease in recurrent episodes after short-term seasonal vortioxetine use without inducing mania or rapid cycling. Conclusion: Our study highlights the potential effectiveness of a seasonal, short-term treatment strategy with antidepressants, including vortioxetine, for winter depression in individuals with BP.
RESUMO
Background: Major depressive disorder (MDD) causes significant functional impairments that impact on all aspects of patients' daily lives, including their ability to work, work productivity, and social life. Purpose: To assess the real-world effectiveness of the multimodal antidepressant vortioxetine in working patients with MDD in China. Patients and methods: RELIEVE China was an observational, prospective cohort study. Patients (aged ≥18 years) with MDD initiating treatment with vortioxetine in routine clinical practice settings were followed for 24 weeks. In this subgroup analysis, functioning was assessed using the Sheehan Disability Scale (SDS) in patients in full- or part-time work or education at baseline who remained on treatment at all follow-up visits (n=424). Depressive, cognitive, and anxiety symptoms were also assessed. For all endpoints, mean change from baseline at weeks 8 and 24 was analyzed using mixed models for repeated measures. Results: Clinically relevant and sustained improvements in patient functioning and measures of work productivity were observed over the 24 weeks of vortioxetine treatment. The adjusted mean (standard error) reduction in SDS total score from baseline was 5.4 (0.3) points at week 8 and 8.7 (0.3) points at week 24 (both P<0.001 vs baseline). Significant improvements were observed across all SDS domains and in levels of absenteeism and presenteeism (P<0.001 vs baseline for all endpoints at both time points). Significant improvements in depressive, cognitive, and anxiety symptoms were also observed over the study period (all P<0.001 vs baseline). The proportion of patients in remission (ie, 17-item Hamilton Depression Rating Scale score ≤7) after 24 weeks of vortioxetine treatment was 65.4%. Vortioxetine was well tolerated; nausea was the most common adverse event, reported by 18.6% of patients. Conclusion: These findings support the effectiveness and tolerability of vortioxetine in working patients with MDD receiving treatment in routine clinical practice settings in China.
RESUMO
Major depressive disorder (MDD) affects millions of people worldwide, with women at a higher risk during the childbearing age. Vortioxetine (VOX) and Vilazodone (VLZ) are newer antidepressants with improved therapeutic profile commonly used, but their safety during pregnancy and long-term effects on offspring are poorly understood due to paucity of literature in preclinical and clinical studies. This study aimed to investigate whether prenatal exposure to VOX and VLZ impacts depressive- and anxiety-like neurobehavioral alterations in offspring, focusing on neurotransmitter-mediated mechanisms. Pregnant Wistar dams received either VOX or VLZ, 1â¯mg/day and 2â¯mg/day of the drug orally from gestation day (GD) 6-21. The dams naturally delivered their offspring and reared until they reached postnatal day (PND) 21. Offspring of both sexes were tested for display of depressive-and anxiety-like behaviors from PND 56-70. After PND 70, offspring were sacrificed, and their brains were collected to estimate neurotransmitter levels. As per protocol, controls were maintained simultaneously for each experimental design. Prenatal exposure to VOX or VLZ induced an increased state of depressive- and anxiety-like behaviors in both male and female offspring. Additionally, neurotransmitter (serotonin, dopamine, and nor-epinephrine) levels in the prefrontal cortex region of the brain were substantially reduced in exposed offspring. No sex specific neurobehavioral and neurochemical implications were observed in the present study. Our findings suggest that prenatal exposure to VOX and VLZ disrupts neurochemical balance in the fetal brain, leading to long-lasting neurobehavioral impairments in offspring of both sexes.

Background: Information about influences of vortioxetine on pregnant women and neonates during perinatal period is almost unknown. Case Presentation: The case was a 28-year-old Japanese woman in her first pregnancy, treated for depression with vortioxetine (20 mg daily) among other medications. At 36 weeks of gestation, she was admitted for premature rupture of the membranes and delivered a girl with no apparent congenital anomalies. Immediately after birth, the neonate required brief respiratory support due to her dyspnea and poor muscle tone. Her respiratory condition improved in 6 days after delivery, and she demonstrated normal developmental progress afterward. Maternal plasma and breast milk samples, collected 4 days postpartum, revealed vortioxetine concentrations of 11.4 ng/mL and 9.3 ng/mL, respectively. The calculated relative infant dose (RID) was estimated at 0.32%. After discharge from hospital, the infant presented no detectable drug-related adverse effects, with over 50% of nutrition derived from breastfeeding. Conclusion: This case showed minimal transfer of vortioxetine into breast milk, reflected in a low RID. The findings suggest limited neonatal exposure to the drug, with no adverse developmental effects observed in the infant. However, the case also indicated the potential for vortioxetine use during pregnancy to contribute to the onset of severe neonatal asphyxia. Further research is needed for a comprehensive understanding of its impact on neonatal health.
RESUMO
Psychotic depression (PD) is a severe mental disorder leading to functional disability and high risk of suicide, but very little is known about the comparative effectiveness of medications used in its maintenance treatment. The objective of this study was to investigate the comparative effectiveness of specific antipsychotics and antidepressants, and their combinations, on the risk of psychiatric hospitalization among persons with PD in routine care. Persons aged 16-65 years with a first-time diagnosis of PD were identified from Finnish (years 2000-2018) and Swedish (years 2006-2021) nationwide registers of inpatient care, specialized outpatient care, sickness absence, and disability pension. The main exposures were specific antipsychotics and antidepressants, and the main outcome measure was psychiatric hospitalization as a marker of severe relapse. The risk of hospitalization associated with periods of use vs. non-use of medications (expressed as adjusted hazard ratio, aHR) was assessed by a within-individual design, using each individual as his/her own control, and analyzed with stratified Cox models. The two national cohorts were first analyzed separately, and then combined using a fixed-effect meta-analysis. The Finnish cohort included 19,330 persons (mean age: 39.8±14.7 years; 57.9% women) and the Swedish cohort 13,684 persons (mean age: 41.3±14.0 years; 53.5% women). Individual antidepressants associated with a decreased risk of relapse vs. non-use of antidepressants were bupropion (aHR=0.73, 95% CI: 0.63-0.85), vortioxetine (aHR=0.78, 95% CI: 0.63-0.96) and venlafaxine (aHR=0.92, 95% CI: 0.86-0.98). Any long-acting injectable antipsychotic (LAI) (aHR=0.60, 95% CI: 0.45-0.80) and clozapine (aHR=0.72, 95% CI: 0.57-0.91) were associated with a decreased risk of relapse vs. non-use of antipsychotics. Among monotherapies, only vortioxetine (aHR=0.67, 95% CI: 0.47-0.95) and bupropion (aHR=0.71, 95% CI: 0.56-0.89) were associated with a significantly decreased risk of relapse vs. non-use of both antidepressants and antipsychotics. In an exploratory analysis of antidepressant-antipsychotic combinations, a decreased relapse risk was found for amitriptyline-olanzapine (aHR=0.45, 95% CI: 0.28-0.71), sertraline-quetiapine (aHR=0.79, 95% CI: 0.67-0.93) and venlafaxine-quetiapine (aHR=0.82, 95% CI: 0.73-0.91) vs. non-use of antidepressants and antipsychotics. Benzodiazepines and related drugs (aHR=1.29, 95% CI: 1.24-1.34) and mirtazapine (aHR=1.17, 95% CI: 1.07-1.29) were associated with an increased risk of relapse. These data indicate that, in the maintenance treatment of PD, bupropion, vortioxetine, venlafaxine, any LAI, clozapine, and only few specific antidepressant-antipsychotic combinations are associated with a decreased risk of relapse. These findings challenge the current recommendation by treatment guidelines to combine an antipsychotic with an antidepressant (without further specification) as standard treatment in PD.
RESUMO
BACKGROUND: Depression is a highly heterogeneous disorder, often resulting in suboptimal response and remission rates. This underscores the need for more nuanced clinical characterization of patients to tailor individualized treatment plans. Emerging evidence highlights the critical role of cognitive and emotional dysfunction in major depression, prompting the exploration of novel therapeutic interventions that target these specific symptom domains. MAIN TEXT: Vortioxetine, a multimodal antidepressant, enhances serotonergic activity while also modulating several other neurotransmitter systems involved in depressive symptoms such as emotional blunting, anhedonia, and cognitive dysfunction. Numerous randomized, placebo-controlled trials have demonstrated vortioxetine's efficacy and safety in treating depression, particularly in specific subgroups of depressed patients, including those with cognitive deficits and comorbid anxiety symptoms or disorders. Although not randomized or placebo-controlled, studies have also shown vortioxetine's efficacy in depressed patients with emotional blunting or anhedonia. Vortioxetine's ability to effectively treat a range of depressive symptoms, including anhedonia, emotional blunting, anxiety, and cognitive dysfunction, provides an individualized treatment solution for depressed individuals suffering from these symptoms. The purpose of this paper is to identify clinical profiles of patients who may benefit from vortioxetine, with the goal of optimizing therapeutic outcomes. CONCLUSION: Vortioxetine has been shown to be effective for patients with depression and symptoms such as anhedonia, emotional blunting, anxiety, and cognitive dysfunction. Tailoring treatment plans to individual needs and personalizing treatment choices based on the specific symptoms presented by depressed patients improve treatment outcomes.
RESUMO
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.
RESUMO
INTRODUCTION: Chronic pain (CP) and depression/anxiety often coexist, worsening each other's symptoms. Treating this comorbidity is challenging. Tricyclic antidepressants and serotonin noradrenaline reuptake inhibitors are the first-line treatment options for this comorbidity, although sometimes they are not effective and/or well tolerated by patients, and there is little clinical evidence that selective serotonin reuptake inhibitors are useful for controlling CP. The antidepressant vortioxetine, with a multimodal mechanism that may help reduce pain, has proven clinical efficacy in patients with major depressive disorder (MDD). This study investigated vortioxetine's effectiveness for MDD and CP in clinical practice. METHODS: This was a 3-month, multicenter, prospective, open-label, non-interventional pharmacoepidemiologic study. Patients (n = 64) with MDD (9-item Patient Health Questionnaire [PHQ-9] score ≥ 15) and CP (visual analogue scale [VAS] score ≥ 4) were treated with vortioxetine for 3 months (initiated with 10 mg/day, with flexible dosing thereafter [5-20 mg/day]). VAS, Clinical Global Impression (CGI), and Patient Global Impression (PGI) scales were used at baseline and at 1 and 3 months. Brief Pain Inventory (BPI), PHQ-9 scale, and Satisfaction with Medicines Questionnaire (SATMED-Q) were used at baseline and at 3 months. Adverse Events (AEs) were recorded. Descriptive statistics, chi-square tests, and Student's t-tests were used for paired data. RESULTS: MDD patients showed a statistically significant improvement in VAS from baseline (mean [standard deviation (SD)]: 7.42 [0.69]) to 1 month (mean [SD]: 6.1 [0.81], P < 0.001) and 3 months (mean [SD]: 5.09 [1.26], P < 0.0001). Similarly, BPI and PHQ-9 scores showed significant improvement from baseline (mean [SD]: 6.20 [0.80] and 16.63 [1.47], respectively) to 3 months (mean [SD]: 4.73 [0.98] and 7.30 [2.60], P < 0.0001, respectively). Patients showed clinical improvement with CGI and PGI scales and reported being satisfied with the treatment in the SATMED-Q. A few mild EAs were registered. CONCLUSION: Vortioxetine can relieve depressive and pain symptoms, with a good safety profile, in patients with MDD and CP.
