Innovative formulations of N,N-dimethyltryptamine (DMT) and 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) enable parenteral and intranasal delivery, respectively. These delivery systems overcome limitations of poor bioavailability and rapid metabolism, offering rapid-onset, short-duration therapeutic effects. The compositions support controlled psychedelic interventions for psychiatric...
Dissociative symptoms are commonly observed in a substantial minority of patients with Post-Traumatic Stress Disorder (PTSD) and during the first administration of esketamine for the treatment of Treatment-Resistant Depression (TRD). We examine differences in the number and pattern of dissociative symptoms (depersonalization, derealization, dissociative amnesia, identity fragmentation) reported...

Background/Objectives: Depression ranks among the most prevalent mental health conditions globally, marked by a variety of symptoms that frequently cause significant emotional distress and impairment in individuals, alongside a high recurrence rate. The predominant approach to treating depression revolves around monoamine theory, utilizing SSRIs and SNRIs, with Esketamine emerging as a...
According to recent research, esketamine may reduce the incidence of postpartum depression (PPD) risk following cesarean delivery. To further assess this potential benefit, a meta-analysis was conducted. Embase, Web of Science, the Cochrane Library, and PubMed were searched from inception through March 2025. Meta-analysis was performed using random-effects models to calculate risk ratios (RRs)...
ABSTRACT: Introduction: About 30% of depressed patients suffer from a protracted course in which the disorder continues to cause significant burden despite treatment efforts. While originally developed for relapse prevention, Mindfulness-Based Cognitive Therapy (MBCT) has increasingly been investigated in depressed patients with such ‘difficult-to-treat’ courses. This is a protocol for an...
Mental health problems that can appear in women during pregnancy include fear, anxiety, feelings of vulnerability, stress, and depression. Mindfulness (MF) is a specific meditation technique that can help during treatment for prenatal mood disorders, emotional distress, and psychological strains. The aim of this study is to determine the effectiveness of a specific meditation approach in women...
Importance: Psychedelic-assisted therapy (PAT) trials have high levels of functional unblinding. This effect positively biases results when PAT trials are compared against truly blinded trials. Objective: This pre-registered meta-analysis investigated the comparative efficacy of PAT and open-label traditional antidepressants (tAD; such as SSRIs and SNRIs) for the treatment of major depression....
Aim: Estimate the cost-per-remitter with esketamine nasal spray plus an oral antidepressant (ESK NS + OAD) versus quetiapine extended release plus an oral antidepressant (QTP XR + OAD) among adults with treatment-resistant depression (TRD). Materials & methods: An Excel-based model was developed to estimate the cost-per-remitter for ESK NS + OAD and QTP XR + OAD from the perspective of a US...
One-third of Veterans with major depressive disorder suffer from treatment-resistant depression (TRD). This is the first study to evaluate the long-term outcomes of psilocybin in Veterans with severe TRD. This paper presents 12-month results from an open-label pilot study assessing the effects of 25 mg psilocybin in Veterans with severe TRD, defined as a major depressive episode failing to...
Treatment-resistant depression (TRD) remains a challenge, with many patients unresponsive to standard antidepressants. NN-dimethyltryptamine (DMT), a fast-acting psychedelic, offers potential benefits due to its rapid onset and short duration. This review, registered with the Open Science Framework (DOI: 10.17605/OSF.IO/6D9WC), summarizes the safety and tolerability of DMT in early-phase...
The rates of relapse and suicide risk are higher in treatment-resistant depression (TRD) vs non-treatment-resistant major depressive disorder. Even among patients with TRD who initially respond, the majority (70%) relapse within 6 months. To evaluate the long-term safety and efficacy of esketamine nasal spray, combined with an oral antidepressant, in patients with TRD. Phase 3, open-label,...
The N-methyl-D-aspartate receptor antagonist ketamine has found broad application in the field of psychiatry. Due to its rapid antidepressant and anti-suicidal properties, it is used as a treatment for major depressive disorder. Furthermore, ketamine evokes dissociative and psychotropic states, which allows the modeling of schizophrenic symptoms. The thalamus, a main target for ketamine's...
We previously completed a double-blind randomised crossover study assessing intramuscular ketamine for treatment-resistant depression (TR-D), post-traumatic stress disorder (TR-PTSD) and obsessive-compulsive disorder (TR-OCD). Here, we report an extension study to explore the ongoing benefits and tolerability of maintenance oral ketamine. All participants from the original study were eligible...

Psychiatric healthcare workers experience prolonged exposure to psychological trauma and negative emotions, which ultimately predisposes them to mental health issues. The effectiveness of online mindfulness-based stress reduction training on depression and anxiety symptoms among psychiatric healthcare workers (HCWs) and the possible mechanisms that benefit these outcomes remain unclear. This...
This trial aimed to assess the efficacy of lysergic acid diethylamide (LSD)-assisted therapy in patients with moderate-to-severe major depressive disorder. This was a randomized, parallel, double-blind, low-dose controlled trial (Clinicaltrials.gov: NCT03866252). Patients were randomly assigned in a 1:1 ratio to receive supportive psychotherapy and either 100 μg + 200 μg LSD or 25 μg + 25 μg...
Despite affecting millions worldwide, major depressive disorder (MDD) remains a therapeutic challenge, with approximately one-third of patients failing to respond to standard treatments. The need for innovative, molecularly driven therapies has turned attention to ketamine and its enantiomers. While S-ketamine is clinically approved for treatment-resistant depression (TRD), it has various...

Ketamine and esketamine (ESK) offer new treatment options for resistant depression. Unlike traditional antidepressants, they can be used in combination with non-selective monoamine oxidase inhibitors (NS-MAOI) without the risk of serotonergic syndrome. However, potential sympathomimetic synergy may lead to elevated blood pressure (BP). This series investigates whether cardiovascular parameters...
