ObjectiveTo determine the efficacy of psilocybin as an antidepressant compared with placebo or non-psychoactive drugs.DesignSystematic review and meta-analysis.Data sourcesFive electronic databases of published literature (Cochrane Central Register of Controlled Trials, Medline, Embase, Science Citation Index and Conference Proceedings Citation Index, and Ps...
Recent years have seen a resurgence in randomized, placebo controlled trials (RCTs) utilizing non-classical psychedelics (e.g. 3,4-methyl enedioxy methamphetamine [MDMA]), and classical psychedelics (e.g. psilocybin, lysergic acid diethylamide [LSD], and N,N-dimethyltryptamine [DMT/ayahuasca]) in conjunction with assisted therapy (AT) for psychiatric disorde...
IntroductionAlcohol Use Disorder (AUD) poses an ongoing significant global health burden. AUD is highly prevalent and affects not only the individuals with AUD, but also their communities and society at large. Even though pharmacotherapy is an integral part of AUD treatment, the few available substances show limited efficacy and limited clinical impact. Thus...
ImportancePsilocybin has been studied in the treatment of depression and anxiety disorders. Clinical studies have mainly focused on efficacy, with systematic reviews showing favorable efficacy; however, none have primarily focused on psilocybin safety.ObjectiveTo evaluate the acute adverse effects of psilocybin at therapeutic doses in the treatment of depres...
BackgroundGrowing clinical interest in psychedelic-assisted therapies has led to a second wave of research involving psilocybin, lysergic acid diethylamide (LSD), 3,4-methylenedioxymethamphetamine (MDMA) and other substances. Data suggests that these compounds have the potential to treat mental health conditions that are especially prevalent in older adults ...
BackgroundInadequate outcomes with monoamine-based treatments in depressive disorders are common and provide the impetus for mechanistically-novel treatments. Esketamine is a proven treatment recently approved for adults with Treatment-Resistant Depression (TRD) while psilocybin is an investigational treatment. Translation of the clinical meaningfulness for ...
IntroductionDepression is a common disabling psychiatric disorder, which - in extreme cases - may lead to suicide if untreated or inadequately treated. Despite the availability of various treatments for depression, including pharmacotherapy, there is still a need to search for new agents with higher effectiveness and faster onset of action, especially for pa...
BackgroundThe classical psychedelics, psilocybin, peyote, ayahuasca/N,N-dimethyltryptamine, and lysergic acid diethylamide are considered promising new treatments for psychiatric illnesses, such as depression, anxiety, addiction, and obsessive-compulsive disorders. However, their profound and characteristic subjective effects raise concern for distinctive bi...
The potential benefits and deficits of the chemical compound psilocybin, particularly when paired with psychotherapeutic interventions, have been increasingly apparent topics of interest in social, academic, and scientific circles. The unusual nature of psilocybin poses many questions in Western culture. Three of them, which will be discussed in the followi...
ObjectiveTo assess the role of psychedelics in the treatment of anxiety or depression among patients with cancer.Data sourcesPubMed search from inception to March 11, 2022, using the terms anxiety, depression, psychedelics, psilocybin, lysergic acid, methylenedioxymethamphetamine, or ayahuasca.Study selection and data extractionStudies assessing patients wit...
Several lines of evidence suggest that classic psychedelics (5-HT2A receptor agonists or partial agonists) such as psilocybin might facilitate behavior change in individuals with substance use disorders. We conducted a multi-site, double-blind, randomized controlled trial (RCT) to assess the effects of psilocybin-assisted psychotherapy in alcohol-dependent v...
IntroductionAlcohol use disorder is a difficult-to-treat psychiatric disorder and a major burden on public health. Existing treatment efficacy is moderate, and relapse rates are high. Preliminary findings suggest that psilocybin, a psychedelic compound, can safely and reliably occasion highly meaningful experiences that may spur a positive change in drinking...
Background: The use of psychedelic compounds to treat psychiatric disorders has become a very significant topic of research over the past several years. Psilocybin has risen to prominence as one of the most studied among these psychedelic compounds. Multiple trials have already shown that it can be a safe and efficacious treatment for various medical conditi...
IntroductionA limited number of preliminary open-label (n = 3) and placebo-controlled clinical trials (n = 5) have suggested psilocybin and LSD as potential rapid antidepressants. In this context, there is a growing need to verify and document their safety and tolerability as therapeutic agents, discuss the challenges associated with their administration, an...
IntroductionPsychedelic drugs were used quite extensively before their prohibition in 1968 which delayed research. However, since the 1990s, studies on the potential therapeutic benefits of psychedelics have rapidly increased.Areas coveredThis systematic review provides an overview of the clinical effects of psilocybin in the treatment of a variety of mental...
IntroductionThere is an imminent need for faster-acting and more effective antidepressants beyond the monoaminergic hypothesis.MethodsWe systematically searched the US Clinical Trials registry for antidepressant compounds with completed phase II and III trials. Compounds that demonstrated significant superiority over placebo in the primary outcome measure in...
Depression is highly prevalent and represents the leading cause of global disability and primary contributor to overall global burden of disease. Several lines of evidence from early-phase experimental trials suggest that serotonergic psychedelics, particularly psilocybin, with therapeutic support show great promise in the treatment of depression with large ...
BackgroundThe therapeutic options for neurobehavioral disorders are still limited, and in many cases, they lack a satisfactory balance between efficacy and side effects.ObjectivesThis work aims to review current evidence regarding the potential contribution of psychedelics and hallucinogens to the discovery of new drugs for treating different psychiatric dis...
BackgroundIboga and its primary alkaloids, ibogaine and noribogaine, have been of interest to researchers and practitioners, mainly due to their putative efficacy in treating substance use disorders (SUDs). For many SUDs, still no effective pharmacotherapies exist. Distinct psychoactive and somatic effects of the iboga alkaloids set them apart from classic h...
Introduction: There is increasing interest in the potential for psychedelic drugs such as psilocybin, LSD and ketamine to treat several mental health disorders, with a growing number of randomized controlled trials (RCTs) being conducted to investigate the therapeutic effectiveness of psychedelics.Areas covered: We review previous literature on expectancy ef...
