Ketamine and its derivates (e.g. esketamine) are increasingly used in clinical settings for treatment-resistant depression (TRD). Ketamine can give rise to acute, cumulative and longer-term side effects (SEs) across a treatment course. The Ketamine Side Effect Tool (KSET) examines adverse effects though its length has affected feasibility for use in clinical settings. To estimate the frequency...
Esketamine is an FDA-approved treatment for treatment-resistant depression (TRD) or major depression with acute suicidal ideation or behavior (MDSI). This analysis addressed the lack of data on real-world characteristics of patients with TRD and MDSI or prescribed esketamine. Data were derived from the Adelphi Real World Depression Disease Specific Programme a cross-sectional survey of...

The understanding of the multiple pathophysiological mechanisms involved in TRD may add further value to the effective treatment, contributing to a more personalized approach. Esketamine was approved for the treatment of TRD and novel drugs with rapid antidepressant actions such as psilocybin and buprenorphine have also been investigated as potential therapeutic strategies. Over the past...
AbstractDepression is the leading cause of disability worldwide. Major Depressive Disorder (MDD) is a condition characterized mostly by low or depressed mood as well as difficulty experiencing emotions, whether positive or negative. Poor adherence has sparked the interest from both physicians and patients in these alternative therapeutic approaches. Ketamine and Electroconvulsive Therapy (ECT)...
Objective: This post hoc analysis of the ESCAPE-TRD trial compared work productivity loss (WPL) and related costs among patients with treatment-resistant depression (TRD) receiving esketamine nasal spray or quetiapine extended release in combination with an oral antidepressant. Methods: Adults with TRD randomized to receive esketamine (56/84 mg) or quetiapine (150-300 mg) combined with ongoing...
Background/Objectives: Ketamine/esketamine has a rapid/robust antidepressant effect on treatment-resistant depression (TRD). However, its long-term cognitive effects remain unclear. In this study, we investigated the potential cognitive effects of an esketamine spray on a series of TRD patients. Methods: We evaluated the cognitive performance of eight TRD patients subjected to an esketamine...

Treatment-resistant depression responds quickly to ketamine. As an N-methyl-d-aspartate receptor (NMDAR) antagonist, ketamine may affect prefrontal cortex (PFC) neurons. Recent investigations reveal that the (R)-enantiomer is the most effective and least abuseable antidepressant. The Food and Drug Administration approves only the (S)-enantiomer for medical usage. (2R,6R)-Hydroxynorketamine...
Background and Clinical Significance: Treatment resistant psychiatric disorders affect millions of people across the globe. Ketamine has been employed as a treatment option for those with treatment resistant depression, as well as for chronic pain and alcohol use disorder. However, case presentations and research has been limited on the outcomes, and furthermore there is even less on the...
This study investigates repeated oral esketamine as a substitution strategy for maintenance electroconvulsive therapy (M-ECT) in eight patients with treatment-resistant depression (TRD). In a 6-week dosing phase, esketamine was titrated from 0.5 or 1.0 mg/kg to a maximum of 3.0 mg/kg twice weekly. Outcomes included 6-week change in Inventory of Depressive Symptomatology - Self-rated (IDS-SR),...
Esketamine nasal spray (ESK) is approved in combination with an oral antidepressant (OAD) for the treatment of adults with treatment-resistant depression (TRD); however, direct comparisons with atypical antipsychotics for TRD are limited. This secondary analysis of the ESCAPE-TRD study compared rates of remission and response, and improvements in depressive symptoms over time, between ESK and...
