Abstract Psilocybin is a classic psychedelic and a novel treatment for mood disorders. Psilocybin induces dose-dependent transient (4-6 hours) usually pleasant changes in perception, cognition, and emotion by non-selectively agonizing the 5-HT 2A receptors and negatively regulating serotonin reuptake, and long-term positive antidepressant effect on mood and well-being. Long-term effects are...
The potent hallucinogen N,N-dimethyltryptamine (DMT) has garnered significant interest in recent years due to its profound effects on consciousness and its therapeutic psychopotential. DMT is an integral (but not exclusive) psychoactive alkaloid in the Amazonian plant-based brew ayahuasca, in which admixture of several β-carboline monoamine oxidase A (MAO-A) inhibitors potentiate the activity...
BACKGROUND: Rapid-acting antidepressants (RAADs), including dissociative anesthetics, psychedelics, and empathogens, elicit rapid and sustained therapeutic improvements in psychiatric disorders by purportedly modulating neuroplasticity, neurotransmission, and immunity. These outcomes may be mediated by, or result in, an acute and/or sustained entrainment of epigenetic processes, which remodel...
One of the main causes of misery and incapacity is chronic pain, which is frequently linked to psychological issues. Psychedelic substances are drugs that can exert a psychological effect on patients. Psychedelic drugs like lysergic acid diethylamide (LSD) and psilocybin, exert their action mainly via activation of the serotonin-2A (5-HT2A).1 In a trial to understand the actual mode of action...
Differentiate between classic psychedelics and their mechanisms of action. Describe how psychedelics influence brain networks, particularly the default mode network, and explain the potential therapeutic implications of these effects on conditions like depression. Outline the key components of psychedelic-assisted therapy, including preparation, support during the psychedelic session, and...
Major Depressive Disorder (MDD) is a common mental health disorder marked by sadness, hopelessness, and anhedonia. Various therapies exist, but their effectiveness is limited. Dextromethorphan hydrobromide combined with bupropion hydrochloride (Auvelity®) is a recently approved alternative for treating this condition in adults. This review summarizes the neurobiology of major depression and...
Rationale: N-methyl-D-aspartate receptor-mediated dissociatives and serotonergic hallucinogens are being increasingly used in therapeutic interventions that involve nonordinary states of consciousness and may represent a unique mental health paradigm wherein pharmacologically induced experiences are conducive to psychological well-being. Objective: The aim of this study was to further...
For more than 20 years, the mainstay of pharmacologic treatment for depression and anxiety disorders has been serotonin reuptake inhibitors and selective serotonin and norepinephrine reuptake inhibitors. There are newer medications, many with novel mechanisms of action, that have come to market; however, first-line treatments remain the same. There are now more robust data on the use of various...
3,4-Methylenedioxymethamphetamine (MDMA, 'ecstasy') is re-emerging in clinical settings as a candidate for the treatment of specific neuropsychiatric disorders (e.g. post-traumatic stress disorder) in combination with psychotherapy. MDMA is a psychoactive drug, typically regarded as an empathogen or entactogen, which leads to transporter-mediated monoamine release. Despite its therapeutic...
SSRIs may not block the subjective or therapeutic effects of psychedelics, but more research is needed. MDMA is completely blocked by SSRIs and SNRIs, while ibogaine has strong QT prolonging effects and should not be combined with other QT prolonging drugs. Ayahuasca contains an MAOI and may cause serotonin syndrome if combined with antidepressants. Lithium and psychedelics may increase seizure...
