This research focuses on the promising use of esketamine in perinatal depression, a widespread disorder impacting postpartum women's mental health. Despite esketamine's known rapid antidepressant effects, its precise mechanisms are not fully understood. This study integrates clinical and preclinical approaches to explore esketamine's efficacy in treating perinatal depression and its actions...
Cortical spreading depolarisation (SD) is a pathological wave of depolarisation in the cortex. SDs occur frequently after severe acute brain injury, and SDs in clusters can contribute to secondary brain damage in patients with severe acute brain injury through hypoperfusion and upregulation of cerebral metabolism in vulnerable brain tissue. Ketamine appears to inhibit SDs both in vitro and in...
INTRODUCTION Anhedonia, defined as the diminished ability to experience or anticipate pleasure, is a core symptom of major depressive disorder (MDD) and bipolar depression (BD), and associated with depression severity, suicidality and poor treatment outcomes. Conventional antidepressants demonstrate limited efficacy against anhedonia. Esketamine nasal spray (ESK-NS) - a novel NMDA receptor...
To investigate the effect of intraoperative low-dose esketamine administered at anesthesia induction on postoperative quality of recovery in total laparoscopic hysterectomy. One-hundred six female patients scheduled for elective total laparoscopic hysterectomy were randomly divided into saline group (group P) and esketamine group (group S). Group P received induction with normal saline,...

Background: Insomnia, as one of the most common sleep disorders, is a significant health problem, especially among patients suffering from drug-resistant depression. Problems related to the quality of sleep in that population can significantly affect the effectiveness of treatment and quality of life, which is why it is necessary to search for effective therapeutic interventions in this area....
Intranasal (IN) esketamine was approved as a therapy for treatment-resistant depression in March 2019. There continues to be interest in the field to better understand factors associated with response to treatment. The aim of the current study is to assess the association between BMI and response to esketamine. A retrospective analysis was conducted on all patients treated with intranasal...
These two cases highlight the utility of a focused, structured clinical phenomenological interview in measuring treatment effectiveness in subjective experience. Two male patients, aged 35 and 27, of Serbian ethnicity with treatment-resistant depression were treated with nasal esketamine, with clinical progress monitored using both the Montgomery-Åsberg Depression Rating Scale (MADRS) and the...
ObjectivesTo review the available evidence, key deliberations, and potential influences behind the Pharmaceutical Benefits Advisory Committee's (PBAC's) conditional recommendation for esketamine to be listed on the Pharmaceutical Benefits Scheme (PBS).ConclusionsThis paper forms part 2 of the esketamine story in Australia-its handling by the Therapeutic Goods Administration (TGA) and,...
We aimed to investigate the relationship between changes in resting-state functional connectivity in a subregion of the hippocampus and the antidepressant effects of esketamine as well as to identify potential neuroimaging markers of the treatment outcomes. Twenty-nine patients with major depressive disorder (MDD) received six intravenous infusions of esketamine. All patients completed the...
The available therapeutic options for post-stroke depression patients are limited. Although SSRIs are the most commonly prescribed antidepressants, their slow onset of action and the higher risk of adverse effects or contraindications have led to an urgent need to develop fast-acting and highly specific antidepressants tailored to the needs of PSD patients. Therefore, ketamine has drawn...
