In Japan, the landscape of clinical practice for substance use disorder is changing significantly, primarily due to an increase in patients using over-the-counter drugs. A major concern is the rising number of patients misusing dextromethorphan (DXM). These patients with DXM use disorders often have severe trauma-related and mood symptoms, and therefore try to cope with those symptoms by...
For depression, ketamine is more conveniently administered by oral than by intravenous (iv) routes. The relative antidepressant efficacy of oral vs iv ketamine is unknown. To assess the acute efficacy and the persistence of improvement with open-label oral versus iv ketamine in outpatients with treatment-resistant depression (TRD). Adults with TRD were randomized to oral (N=30) or IV (N=31)...
Catatonia, documented since the 19th century, remains a significant challenge in terms of recognition and treatment. Over the last two decades, ketamine has brought new perspectives to psychiatry, sparking widespread interest. Concurrently, catatonia has attracted heightened scientific attention. Preliminary evidence suggests the therapeutic potential of ketamine for catatonia. We...

Esketamine, the s(+) enantiomer of ketamine, was approved in 2019 as the first rapid-acting intranasal spray medication for treatment-resistant depression; the drug is given in combination with an antidepressant. The treatment is self-administered in a clinical setting under the supervision of a healthcare provider and usually is well tolerated. Many of its adverse reactions are mild,...
The aim of this study was to explore the use of perinatal ketamine to see if it can be used for the reduction of postpartum depression (PPD) following cesarean section (C-section). PubMed, Cochrane, and Web of Science were the primary databases used for this review. Search terms used on January 5, 2024 incorporated "ketamine," "C-section," "postpartum depression," and related synonyms. The...
Glutamic acid decarboxylase 67 (GAD67) is a gamma-aminobutyric acid (GABA) synthesis enzyme associated with the function of other neurotransmitter receptors, such as the N-methyl-D-aspartate (NMDA) receptor and cannabinoid receptor 1. However, the role of GAD67 in the development of different abused drug-induced reward behaviors remains unknown. In order to elucidate the mechanisms of substance...

Ketamine, a dissociative anesthetic primarily recognized for its antagonism of N-methyl-D-aspartate (NMDA) receptors, has gained significant attention for its rapid antidepressant effects and potential in treating mood disorders. However, recent research indicates that ketamine's influence extends beyond NMDA receptor inhibition, affecting α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid...
Serotonergic psychedelics and ketamine produce rapid and long-lasting symptomatic relief in multiple psychiatric disorders. Evidence suggests that despite having distinct molecular targets, both drugs may exert therapeutic benefit via their pro-neuroplastic effects. Following treatment with ketamine or serotonergic psychedelics, patients are reported to be more open to behavioral change, which...
Ketamine therapy can reduce the risk of suicide and depression in the treatment resistant patient. Adverse effects of ketamine infusion include blurred vision, nausea and vomiting, hepatotoxicity, headache, and cystitis. However, the effect of ketamine infusion on blood glucose remains unclear. This report describes several episodes of hypoglycemia in a 36-year-old man with type 1 diabetes...

Aim: In this review, we assessed the state of available knowledge regarding the antidepressant action of intravenous ketamine versus electroconvulsive therapy (ECT) in randomized clinical trials and clinical trials. Methods: To search for the eligible articles, the PubMed database was used. Five studies were selected using the inclusion criteria, and their findings are presented in our review....
