Ascending‐Dose Study of Controlled‐Release Ketamine Tablets in Healthy Volunteers: Pharmacokinetics, Pharmacodynamics, Safety, and Tolerability

The Journal of Clinical Pharmacology February 17, 2020 Paul Glue, Natalie J. Medlicott, Peter Surman et al. 44 citations

Parenteral ketamine has fast‐onset antidepressant and antianxiety effects; however, it causes dissociation, hypertension, and tachycardia shortly after dosing. Ketamine's antidepressant effects may be due to active metabolites rather than to ketamine itself. We hypothesized that oral controlled‐release ketamine tablets would improve safety and tolerability compared with injected ketamine by...

Overlap in the neural circuitry and molecular mechanisms underlying ketamine abuse and its use as an antidepressant.

Behavioural Brain Research February 13, 2020 S. Kokane, Ross J. Armant, Carlos A. Bolaños-Guzmán et al.

Ketamine, a dissociative anesthetic and psychedelic compound, has revolutionized the field of psychopharmacology by showing robust, and rapid-acting antidepressant activity in patients suffering from major depressive disorder (MDD), suicidal tendencies, and treatment-resistant depression (TRD). Ketamine’s efficacy, however, is transient, and patients must return to the clinic for repeated...

Antidepressant-like effects of ketamine in a mouse model of serotonergic dysfunction.

Neuropharmacology February 12, 2020 C. Wilson, Shanshan Li, Anthony J. Hannan et al.

Traditional monoaminergic treatments of depression frequently exhibit suboptimal tolerability and effectiveness. The 'short' (s) allele variant of 5-HTTLPR is known to compromise transcriptional efficacy of the serotonin transporter (5-HTT) and can reduce treatment response to traditional antidepressants (e.g. selective serotonin reuptake inhibitors or SSRIs). This study sought to establish the...

Safety and Tolerability of Ketamine Use in Treatment-Resistant Bipolar Depression Patients with Regard to Central Nervous System Symptomatology: Literature Review and Analysis

Medicina February 9, 2020 Adam Włodarczyk, Wiesław Jerzy Cubała 22 citations

The current psychopharmacological treatment approaches for major depression focus on monoaminergic interventions, which are ineffective in a large proportion of patients. Globally, treatment-resistant bipolar depression (TRBD) affects up to 33% of depressive patients receiving treatment. Certain needs are still unmet and require new approaches. Many studies are in favor of treatments with...

Ketamine Alleviates Postoperative Depression-Like Symptoms in Susceptible Mice: The Role of BDNF-TrkB Signaling

Frontiers in Pharmacology February 6, 2020 Shan Li, Xiaoxiao Luo, Dongyu Hua et al.

Patients are more likely to suffer from central nervous system (CNS) complications after anesthesia and surgery. However, postoperative depression (POD) has not yet received sufficient attentions, and its pathogenesis and therapeutic strategies remain poorly understood. We here aimed to investigate whether brain derived neurotrophic factor (BDNF)-tropomyosin-related kinase B (TrkB) signaling...

A historical review of antidepressant effects of ketamine and its enantiomers.

Pharmacology, Biochemistry, and Behavior February 5, 2020 Yan Wei, Lijia Chang, Kenji Hashimoto 157 citations

The robust antidepressant effects of (R,S)-ketamine are among the most important discoveries in mood research over the last half century. Off-label use of (R,S)-ketamine, which is an equal mixture of (R)-ketamine and (S)-ketamine, has become especially popular in the United States (US) for treatment-resistant depression. On March 5, 2019, the US Food and Drug Administration approved an...

Low-dose ketamine improves LPS-induced depression-like behavior in rats by activating cholinergic anti-inflammatory pathways.

ACS Chemical Neuroscience February 3, 2020 Jinghua Zhao, XueJie Liu, Daiyue Chang et al.

About 16% of the world's population has major depressive disorder. Traditional antidepressants have slow effect rates and low response rates. Many studies have shown that low doses of ketamine can produce rapid and effective antidepressant effects. However, its mechanism of action needs further exploration. Lipopolysaccharide (LPS) was used to establish a depression model in rats and PC12 nerve...

Ketamine, Esketamine, and A New Generation of Antidepressants

Psychiatric Annals February 1, 2020 Samuel T. Wilkinson, Brandon Kitay

Since the discovery of its rapid-acting antidepressant properties, ketamine has helped stimulate a new line of research in the development of rapid-acting antidepressants based on the glutamate and gamma-aminobutyric acid neurotransmitter systems. An intranasal version of the S-enantiomer of ketamine (esketamine) recently received regulatory approval as a therapy for treatment-resistant...

Comparative Efficacy of Ketamine in Treatment-Resistant Depression

Psychiatric Annals February 1, 2020 Hatice Guncu Kurt, Murat Altinay, Amit Anand

Patients who have not responded to two antidepressant trials in their current depressive episode are usually considered to have treatment-resistant depression (TRD). A detailed search on PubMed was conducted for reported response and remission rates for non-ketamine and ketamine treatments for TRD. From a variety of pharmacological and brain stimulation open-label studies, the treatments were...

Neurobiological Mechanisms of Ketamine: Depression, Suicide, Trauma, and Chronic Stress Pathologies

Psychiatric Annals February 1, 2020 Lynnette A. Averill, Christopher L. Averill, Chadi G. Abdallah 6 citations

The serendipitous discovery of ketamine's robust antidepressant effects has served as a major catalyst to usher in new era of drug development and a paradigm shift in our understanding of the neurobiology of chronic stress pathology (CSP). This review provides a selective synthesis of (1) the historical foundations of N-methyl-D-aspartate receptor modulators and the path to discovering...
