Traditional antidepressants are limited by delayed onset, creating a need for rapidly acting therapies. In this Palliative Care Rounds, we examine the evidence for ketamine/esketamine's efficacy as a …
"Preliminary evidence demonstrates that Ketamine-Assisted Psychotherapy (KAP) can significantly improve depression, demoralization and existential distress in seriously ill people"

Managing acute pain in older adults is a complex challenge in emergency care, influenced by age-related physiological changes, multimorbidity and altered pharmacokinetics. Inadequate treatment contributes to frailty, delirium, functional decline and reduced quality of life, yet oligoanalgesia remain …

BackgroundKetamine has demonstrated efficacy in treatment-resistant depression, primarily in psychiatric or outpatient populations. Its use in ICU patients remains underexplored, with limited data beyond case reports and small series. This study evaluated the association between subanesthetic ketami …

Esketamine demonstrates efficacy in achieving rapid relief of depressive symptoms in TRD, but findings must be interpreted with caution, given the heterogeneity and adverse event profile. Further high-quality, long-term studies are warranted to establish sustained efficacy and safety.

Ketamine's rapid antidepressant actions are commonly attributed to glutamatergic mechanisms. In a recent study, Luo and colleagues have shown that ketamine inhibits the serotonin transporter and that prefrontal serotonergic signaling synergizes with NMDA receptor blockade to recruit vasoactive intes …
