Major depressive disorder (MDD) continues to pose a major therapeutic challenge due to its clinical heterogeneity. This chapter looks at the development of antidepressant treatments, starting with early interventions such as electroconvulsive therapy (ECT), monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants (TCAs). Although these treatments t...
The study looks into whether administering psychedelic substances that stimulate the serotonin system influences pro-social behavior when compared to administering substances that stimulate the dopamine system in healthy individuals. Psychedelic substances have been shown to be powerful modulators of social perception and behavior during the acute experience...
Anhedonia is a transdiagnostic domain that leads to poor disorder outcome and low remission rates. This narrative review describes a broad range of interventions targeting anhedonia, including pharmacological, neuromodulatory, behavioral, and lifestyle-based approaches. Drugs such as vortioxetine, agomelatine, bupropion, ketamine, and brexpiprazole show prom...
4-bromo-2,5-dimethoxyphenethylamine (2C-B) is a psychoactive substance with reportedly similar acute effects to both the prototypical empathogen 3,4-methylenedioxymethamphetamine (MDMA, Ecstasy) and the classic psychedelic substance psilocybin (contained in "magic, hallucinogenic mushrooms"). Pharmacologically, MDMA mainly releases serotonin (5-HT) via the s...
Brain aging (BA) processes are complex, often affect multiple systems, and frequently lead to cognitive decline and increased susceptibility to insults. BA appears to be a primary risk for the development of many prominent neurodegenerative pathologies. The US Census Bureau predicts that the aging population (65+) will represent a greater proportion of the U...
In the contemporary landscape of psychiatric medicine, critical advancements have been noted in the utilization of psychoactive substances such as hallucinogens, 3,4-methylenedioxymethamphetamine (MDMA), and ketamine for the treatment of severe mental health disorders. This review provides a detailed evaluation of these substances, focusing on their mechanis...
Introduction Since the last edition of the Black Book, several innovative agents have been approved or are poised to be approved in the coming year. These include novel antidepressants, the first muscarine agonist for the treatment of schizophrenia, the first psychedelic which may be approved for the treatment of PTSD (Post Traumatic Stress Disorder), and th...
Data on medication interactions with psychedelics are limited. Here we present what may be the first published report of a hypertensive emergency following the combination of psilocybin mushrooms with a monoamine oxidase inhibitor (MAOI). A42-year-old man with treatment-resistant major depressive disorder took 1 g of Psilocybe cubensis mushrooms, while presc...
BACKGROUND: There is growing evidence for the therapeutic effects of the psychedelic drug psilocybin for major depression. However, due to the lack of safety data on combining psilocybin with selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) and concerns that there may be a negative interaction on effica...
Background: Psilocybin is being studied for depression, but little is known about how it interacts with common antidepressants. Limited data suggest that psilocybin’s effects may be diminished by serotonergic antidepressants acutely and even after a medication washout period. Aims: To learn the extent to which antidepressants may diminish the effects of psil...
Major Depression Disease is a common mental illness that affects more than 322 million people worldwide and it is one of the leading causes of mental and physical disability. The etiology of depression is a complex interplay of psychological, social, and biological factors. Currently, psychopharmacotherapy is based mainly on the monoamine theory, which state...
Purpose of reviewThis review examines recent evidence that informs the treatment of anxiety-related disorders.Recent findingsIn addition to selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), and benzodiazepines, agomelatine has demonstrated efficacy in treating generalized anxiety disorder (GAD). Other ...

Opinion statementPreventing depression in cancer patients on long-term opioid therapy should begin with depression screening before opioid initiation and repeated screening during treatment. In weighing the high morbidity of depression and opioid use disorder in patients with chronic cancer pain against a dearth of evidence-based therapies studied in this po...
Many psychoactive compounds have been shown to primarily interact with high-affinity and low-capacity solute carrier 6 (SLC6) monoamine transporters for norepinephrine (NET; norepinephrine transporter), dopamine (DAT; dopamine transporter) and serotonin (SERT; serotonin transporter). Previous studies indicate an overlap between the inhibitory capacities of s...
It is well established that a wide range of drugs of abuse acutely boost the signaling of the sympathetic nervous system and the hypothalamic-pituitary-adrenal (HPA) axis, where norepinephrine and epinephrine are major output molecules. This stimulatory effect is accompanied by such symptoms as elevated heart rate and blood pressure, more rapid breathing, in...
Treatment of major depressive disorder (MDD) including treatment-resistant depression (TRD) remains a major unmet need. Although there are several classes of dissimilar antidepressant drugs approved for MDD, the current drugs have either limited efficacy or are associated with undesirable side effects and withdrawal symptoms. The efficacy and side effects of...
Hallucinogens constitute a unique class of substances that cause changes in the user's thoughts, perceptions, and mood through various mechanisms of action. Although the serotonergic hallucinogens such as lysergic acid diethylamide, psilocybin, and N,N-dimethyltryptamine have been termed the classical hallucinogens, many hallucinogens elicit their actions th...
The present study investigated interactions between the novel psychoactive tryptamines DiPT, 4-OH-DiPT, 4-OH-MET, 5-MeO-AMT, and 5-MeO-MiPT at monoamine receptors and transporters compared with the classic hallucinogens lysergic acid diethylamide (LSD), psilocin, N,N-dimethyltryptamine (DMT), and mescaline. We investigated binding affinities at human monoami...
