Background/Objectives: In this study, we present an analysis of ayahuasca, a psychedelic preparation containing N,N-dimethyltryptamine (DMT) and β-carbolines, such as harmine (HRM), a reversible monoamine oxidase A (MAO-A) inhibitor that enables the oral bioavailability of DMT. CYP2D6 is a highly polymorphic enzyme associated with interindividual variability in drug exposure, but its influence...

Chronic pain is common, costly, and for many, remains inadequately treated by existing pharmacologic and non-pharmacologic approaches. In parallel with growing dissatisfaction with conventional therapies, classic serotonergic psychedelics, such as psilocybin, lysergic acid diethylamide (LSD), ayahuasca, N,N-dimethyltryptamine (DMT), and mescaline, administered alone or within...
Abstract Background Prolonged grief disorder (PGD) is a clinically distinguishable bereavement-related condition characterized by persistent yearning, identity disruption, and impaired functioning, formalized in DSM-5-TR and ICD-11 (6L72) and empirically distinguishable from but frequently co-occurring with major depressive disorder. Approximately 7 to 10 percent of bereaved adults meet...

Introduction Psychedelics are hallucinogenic agents that are awakening scientific interest in recent years, especially in the field of mental health. Psychedelics induce non-ordinary states of consciousness and alterations in the emotions and in cognition and could be beneficial in treating some mental illness. Objectives The objective of the poster is to expand knowledge about emerging...
Abstract The last decade has seen a remarkable resurgence of interest in psychedelic drugs such as psilocybin (from magic mushrooms) LSD and DMT (dimethyl tryptamine – the active ingredient of ayahuasca). This has been driven by the discovery that these psychedelics all act agonists of 5-HT2A receptors plus human imaging studies that reveal this action leads to profound alterations in brain...
Classical psychedelics such as N,N -dimethyltryptamine (DMT) modulate consciousness via serotonergic receptor agonism, and are increasingly investigated for their psychotherapeutic potential. When combined with the monoamine oxidase A (MAO-A) inhibitor harmine—mimicking the pharmacological profile of ayahuasca—oral DMT induces a psychedelic experience lasting 4–5 h. While some neuroimaging...

The impact of classic psychedelics (5-HT2A receptor agonists) on personality traits has been studied for decades, and it has been hypothesized that the mechanisms underlying these changes are linked to agonism at cortical serotonergic 5-HT2A receptors. However, research results are contradictory. Therefore, the present paper aims to systematically evaluate the effects of psychedelics on...
Os transtornos psiquiátricos representam importante problema de saúde pública mundial, frequentemente associados a elevada morbidade, incapacidade funcional e impacto significativo na qualidade de vida. Apesar dos avanços terapêuticos disponíveis, muitos pacientes permanecem refratários aos tratamentos convencionais, estimulando a busca por novas abordagens terapêuticas. Nesse contexto, os...
