Download or read book Ketamine written by Kenji Hashimoto and published by Springer Nature. This book was released on 2020-03-05 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest data from basic research and clinical trials supporting the effectiveness of ketamine as a treatment for depression, bipolar disorder, and suicidal behavior, setting these positive findings within the context of the serious problem of ketamine abuse. The first part of the book focuses on the evidence regarding ketamine abuse, with specific reference to Asian countries, and discusses countermeasures and complication management. It then addresses the mechanisms underlying the antidepressant and side effects of ketamine, which have remained elusive, describing and discussing important new research findings. Further, it explains insights gained from whole brain imaging in rodents and from behavioral pharmacology, and presents evidence regarding the role of gut microbiota, the NMDA receptor GluN2D subunit, and the lateral habenula in the actions of ketamine. These advances form the basis for the safer use of ketamine in patients with treatment-resistant depression and are expected to lead to the development of new antidepressants.
Download or read book Ketamine for Treatment Resistant Depression written by Sanjay J. Mathew and published by Springer. This book was released on 2016-11-25 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together an international group of clinicians and researchers from a broad swath of inter-related disciplines to offer the most up-to-date information about clinical and preclinical research into ketamine and second-generation “ketamine-like” fast-acting antidepressants. Currently available antidepressant medications act through monoaminergic systems, are ineffective for many individuals suffering from depression, and are associated with a delayed onset of peak efficacy of several months. The unexpected emergence of ketamine, an anesthetic N-methyl-D-aspartate (NMDA) receptor antagonist, as a rapid-acting antidepressant has reinvigorated CNS drug discovery research and catalyzed investigation in patient populations historically ignored in antidepressant drug development programs, particularly treatment-resistant patients and those with suicidality. Recent industry and academic research efforts have coalesced to explore NMDA receptor and glutamatergic molecular targets that lack ketamine’s psychotomimetic side effects and abuse liability but retain its rapid onset of efficacy. However, many fundamental questions remain regarding the neurobiological mechanisms underlying ketamine’s rapid antidepressant effects and the puzzling persistence of benefits observed in some patients following a single dose. This book examines how insights from these studies are forging new conceptual models of the neurobiology of stress-related affective, anxiety, and addictive disorders and the nature of treatment resistance. It also discusses how ketamine’s rapid antidepressant effects provide a scientific platform to facilitate innovation in clinical trial designs pertaining to patient selection, choice of control group, outcome measures, and dose-optimization. This book brings together data and insights from this rapidly expanding and extraordinarily promising field of study. Readers will be able to extract integrated themes and useful insights from the material contained in these diverse chapters and appreciate the paradigm-shifting contributions of ketamine to modern psychiatry and clinical neuroscience research.
Download or read book Emergence of Ketamine as a Rapid Acting Antidepressant written by Preet Mohinder Singh Bedi and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ketamine is a phencyclidine derivative and N-methyl-D-aspartate receptor antagonist, widely popular as a dissociative anesthetic. Its use as an anesthetic in humans was progressively fallen out due to its associated adverse effects and the emergence of newer and safer anesthetics. In recent few decades, various reports related to its efficacy in the treatment of resistant depression with anti-suicidal potential draw significant attention from researchers around the globe. The rapid clinical effect of ketamine within hours as compared to traditional antidepressants that take several weeks makes it a hot topic in antidepressant research. Studies conducted in the recent past suggest its mechanism of action through glutamate modulation via receptors like NMDA, AMPA as well as downregulation of BDNF etc. This chapter will shed light on the various mechanisms of ketamine related to antidepressant activity. Along with that its pharmacokinetics, toxicology and ongoing clinical trials will also be discussed.

Download or read book New Rapid acting Antidepressants written by Kenji Hashimoto and published by Springer Nature. This book was released on 2021-10-22 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses new candidates for rapid-acting antidepressants, such as (R)-ketamine, (2R,6R)-hydroxynorketamine, scopolamine, mGluR2/3 antagonists and AMPA receptor agonists. There are serious limitations to currently available antidepressants, such as delayed onset and low rates of efficacy. The discovery that a single dose of ketamine, an NMDAR antagonist, can produce rapid antidepressant effects that are sustained has led to new research in this area. In this volume, a variety of novel pharmaceutical treatments are examined. This volume would be useful to both researchers and clinicians who work in the field of pharmacology, specifically CNS drug treatments.

Download or read book The Molecular Mechanisms Underlying Ketamine s Rapid Antidepressant Responses written by Ke Zhang and published by . This book was released on 2015 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Major depressive disorder (MDD) is a serious public health problem that is prevalent in the United States and all over the world. Despite the high incidence of MDD and its socioeconomic impact, the etiology of MDD remains largely unknown. Current traditional antidepressants used in clinical treatment are far from ideal. They usually take weeks to months to produce efficiency. And high risk of suicide is another factor to limit their application. Moreover, nearly 30% of the patients with depression are resistant to traditional antidepressant treatment. Recent evidence from clinical trials shows that a single subanesthesia dose (0.5-20 mg/kg) of ketamine, a noncompetitive ionotropic glutamatergic NMDA receptor antagonist, produces rapid antidepressant responses in patients suffering from MDD. However, recent studies on the mechanism underlying ketamine's fast-acting antidepressant effect are controversial. Moreover, the psychotomimetic properties and abuse potential of ketamine necessitate caution in promoting this compound as a general treatment for depression. Understanding the underlying mechanism of action of ketamine linked to behavioral improvement is of significant importance for developing novel, safe and fast-acting antidepressants. In the current study, we provide evidence to support a new hypothesis on how NMDA receptor blockage induces fast antidepressant effect, which is quite different from the prevalent theories about fast antidepressant action of ketamine.In this study we observed that ketamine potentiates the excitatory synaptic transmission by recording fEPSP and whole-cell EPSC, which is dependent on PKA activation. More AMPA GluR1 receptors expressed on membrane surface by ketamine-enhanced phosphorylation of GluR1 at site Ser845. Additionally for the upstream signaling of ketamine-induced potentiation of synaptic transmission, we found that ketamine blocks presynaptic NMDA receptors and decrease presynaptic HCN channel expressions which leads to an increase of presynaptic glutamate release, and thus enhanced postsynaptic responses by PKA activation pathways.

Download or read book Modern Anesthetics written by Jürgen Schüttler and published by Springer Science & Business Media. This book was released on 2008-01-08 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some important constraints of anesthesia must be taken into consideration when the pharmacological properties of modern anesthetics are discussed. The most imp- tant of these could be that the target effect be achieved preferably within seconds, at most within a few minutes. Similarly, offset of drug action should be achieved within minutes rather hours. The target effects, such as unconsciousness, are pot- tially life-threatening, as are the side effects of modern anesthetics, such as respi- tory and cardiovascular depression. Finally, the patient’s purposeful responses are not available to guide drug dosage, because, either the patient is unconscious, or more problematically, the patient is aware but unable to communicate pain because of neuromuscular blockade. These constraints were already recognised 35 years ago, when in 1972 Volume XXX entitled “Modern Inhalation Anesthetics” appeared in this Handbook Series. The present volume is meant as a follow up and extension of that volume. At the beginning of the 1970’s anesthesia was commonly delivered by inhalation, with only very few exceptions. The clinical understanding of that time considered anesthesia as a unique state achieved by any of the inhalation anesthetics, in- pendent of their specific molecular structure. “The very mechanism of anesthetic action at the biophase” was discussed within the theoretical framework of the “u- tary theory of narcosis”.
Download or read book Statistical Methods in Psychiatry and Related Fields written by Ralitza Gueorguieva and published by CRC Press. This book was released on 2017-11-20 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data collected in psychiatry and related fields are complex because outcomes are rarely directly observed, there are multiple correlated repeated measures within individuals, there is natural heterogeneity in treatment responses and in other characteristics in the populations. Simple statistical methods do not work well with such data. More advanced statistical methods capture the data complexity better, but are difficult to apply appropriately and correctly by investigators who do not have advanced training in statistics. This book presents, at a non-technical level, several approaches for the analysis of correlated data: mixed models for continuous and categorical outcomes, nonparametric methods for repeated measures and growth mixture models for heterogeneous trajectories over time. Separate chapters are devoted to techniques for multiple comparison correction, analysis in the presence of missing data, adjustment for covariates, assessment of mediator and moderator effects, study design and sample size considerations. The focus is on the assumptions of each method, applicability and interpretation rather than on technical details. Features Provides an overview of intermediate to advanced statistical methods applied to psychiatry. Takes a non-technical approach with mathematical details kept to a minimum. Includes lots of detailed examples from published studies in psychiatry and related fields. Software programs, data sets and output are available on a supplementary website. The intended audience are applied researchers with minimal knowledge of statistics, although the book could also benefit collaborating statisticians. The book, together with the online materials, is a valuable resource aimed at promoting the use of appropriate statistical methods for the analysis of repeated measures data. Ralitza Gueorguieva is a Senior Research Scientist at the Department of Biostatistics, Yale School of Public Health. She has more than 20 years experience in statistical methodology development and collaborations with psychiatrists and other researchers, and is the author of over 130 peer-reviewed publications.
