More than 280 million individuals worldwide suffer from depression, which is one of the main causes of mental disability. It has multiple subtypes, and conventional treatments have limitations such as slow onset of action, high non-response rate, and numerous side effects. For instance, it takes two to six weeks for selective serotonin reuptake inhibitors (SSRIs) to start working, and about 30%...

Depression, projected to be the leading cause of global disability by 2030, affects up to 19.62% of Pakistan's population. Treatment-resistant depression (TRD), characterized by poor response to at least two antidepressants, poses a major clinical challenge. Although interventions like ECT exist, their use is limited by systemic barriers. Esketamine, an NMDA receptor antagonist, offers a...

Esketamine rapidly improved suicidality and depression in TRD, with preliminary evidence suggesting gender-specific responses, and highlighting the importance of tailored interventions to maximize outcomes. Further research is needed to confirm these differences, explore the long-term effects, and understand the underlying mechanisms.

This case report discusses a 62-year-old male with treatment-resistant bipolar II depression and hypertension. After poor responses to multiple treatments, an add-on esketamine nasal spray (ESK-NS) was introduced in October 2022. Improvement was seen, and the patient's depressive episode was nearly remitted during the maintenance phase. However, recurrence was noted when ESK-NS frequency was...

Clinical response and remission may not fully reflect patient priorities in treatment-resistant depression (TRD). Health-related quality-of-life (HRQoL) outcomes should be assessed to comprehensively capture treatment benefits. ESCAPE-TRD (NCT04338321) was a 32-week randomized, phase IIIb trial comparing esketamine nasal spray (NS) versus quetiapine extended release (XR), both alongside an...

Major depressive disorder (MDD) frequently co-occurs with substance use disorders (SUDs), leading to poorer outcomes and limited options. Esketamine is approved for treatment-resistant depression (TRD); its effects on craving and abstinence in SUD are less explored. A 41-year-old man with recurrent MDD (suicidal ideation) and polysubstance use (daily morphine/prescription opioids; intermittent...

Abstract Background: Intranasal esketamine has gained attention as a rapidly acting intervention for treatment-resistant depression, and there is growing interest in its potential anti-obsessional effects. To our knowledge, no published case series has focused on intranasal esketamine in patients with both treatment-resistant obsessive–compulsive disorder (TR‑OCD) and comorbid major depression...
