UTILIZAÇÃO DE PSICODÉLICOS NO TRANSTORNO DEPRESSIVO REFRATÁRIO: UMA REVISÃO DE LITERATURA

Revista CPAQV - Centro de Pesquisas Avançadas em Qualidade de Vida October 4, 2024 Claudio Mateus Gnoatto, Keyla Liana Bezerra Machado, Rian Ricardo Henrique da Silva et al.

Introdução: O Transtorno Depressivo Maior (TDM) é altamente prevalente e incapacitante, ocupando um alto ônus globalmente. No Brasil, afeta 15,5% da população. A fisiopatologia da depressão envolve teorias, incluindo a monoaminérgica e a dos receptores monoaminérgicos, embora nenhuma seja conclusiva. Tratamentos farmacológicos baseiam-se na teoria monoaminérgica, apesar de suas limitações. Além...

Chemistry/structural biology of psychedelic drugs and their receptor(s).

British Journal of Pharmacology October 2, 2024 Ryan H. Gumpper, David E Nichols 9 citations

This brief review highlights some of the structure-activity relationships of classic serotonergic psychedelics. In particular, we discuss structural features of three chemotypes: phenethylamines, ergolines and certain tryptamines, which possess psychedelic activity in humans. Where they are known, we point out the underlying molecular mechanisms utilized by each of the three chemotypes of...

Evaluation of potential punishing effects of 2,5-dimethoxy-4-methylamphetamine (DOM) in rhesus monkeys responding under a choice procedure.

Behavioural Pharmacology October 1, 2024 David R Maguire 2 citations

There has been substantial and growing interest in the therapeutic utility of drugs acting at serotonin 2A subtype (5-HT 2A ) receptors, increasing the need for characterization of potential beneficial and adverse effects of such compounds. Although numerous studies have evaluated the possible rewarding and reinforcing effects of 5-HT 2A receptor agonists, there have been relatively few studies...

Autism, youth suicide, and psychedelics: A review of the 21st century evidence.

Journal of the Chinese Medical Association : JCMA October 1, 2024 Mu-Hong Chen, Tung-Ping Su, Ju-Wei Hsu et al. 14 citations

The concurrent rise in the prevalence of autism and youth suicide has drawn public health and professional attention. The renaissance of psychedelics in psychiatry occurred in the early 21st century and may suggest a hope for the therapeutic effect of psychedelics in autism and suicide. The psychedelics' molecular entities are the compounds that modulate the serotoninergic and glutamatergic...

Defined radio wave frequencies attenuate the head-twitch response in mice elicited by (±)-2,5-dimethoxy-4-iodoamphetamine.

Electromagnetic biology and medicine October 1, 2024 Mary O Vu, B Michael Butters, Clinton E. Canal et al. 1 citation

Results from clinical trials show that serotonergic psychedelics have efficacy in treating psychiatric disorders, where currently approved pharmacotherapies are inadequate. Developing psychedelic medicines, however, comes with unique challenges, such as tempering heightened anxiety associated with the psychedelic experience. We conceived a new strategy to potentially mitigate psychedelic...

Psilocybin and 2C-B at Encoding Distort Episodic Familiarity.

Biological Psychiatry: Cognitive Neuroscience and Neuroimaging October 1, 2024 Manoj K. Doss, Pablo Mallaroni, Natasha L. Mason et al. 7 citations

As research on psychedelics (hallucinogenic serotonin receptor 2A agonists) progresses, it is important to delineate the reliability of supposedly unique effects across this drug class. One such effect is how psychedelics impair the formation (i.e., encoding) of hippocampal-dependent recollections (retrieval of specific details) while potentially enhancing the encoding of cortical-dependent...

Acute dose-dependent effects of mescaline in a double-blind placebo-controlled study in healthy subjects.

Translational Psychiatry September 30, 2024 Aaron Klaiber, Yasmin Schmid, Anna M Becker et al. 27 citations

Classic psychedelics have regained interest in research and therapy. Despite the long tradition of the human use of mescaline, modern data on its dose-dependent acute effects and pharmacokinetics are lacking. Additionally, its mechanism of action has not been investigated in humans. We used a randomized, double-blind, placebo-controlled, crossover design in 16 healthy subjects (8 women) who...

The Action on Psilocybin in Neural Plasticity, Brain Reorganization and Cognitive Enhancement

Middle East Research Journal of Biological Sciences September 28, 2024 Carlos Henrique Marchiori, Marco Vinícios de Oliveira Santana, Klebert de Paula Malheiros

Psilocybin and psilocin do not cause addiction or dependence, as they do not interact with the dopaminergic reward system. New pharmacological treatment strategies for substance abuse disorders have targeted craving, which is characterized, in a simplified way, by an intense desire to use the substance. Psilocybin is an indole alkaloid of the hallucinogenic tryptamine group whose molecular...

The Effectiveness of Ketamine Treatment on Depression

Communications in Humanities Research September 27, 2024 Yichen Liu

As the diagnosis rate of depression continues to rise, effective treatment options for this condition have become one of the most researched areas in the field. Earlier antidepressants were primarily developed based on mechanisms that involve regulating imbalanced neurotransmitters. For example, the widely known Selective Serotonin Reuptake Inhibitors (SSRIs) and various tricyclic...

How to make psychedelic-assisted therapy safer

Cambridge Quarterly of Healthcare Ethics September 27, 2024 Daniel Villiger 10 citations

Classic serotonergic psychedelics are experiencing a clinical revival, which has also revived ethical debates about psychedelic-assisted therapy. A particular issue here is how to prepare and protect patients from the vulnerability that the psychedelic state creates. This paper first examines how this vulnerability manifests itself, revealing that it results from an impairment of autonomy:...
