3,4-methylenedioxymethamphetamine or MDMA (known as "ecstasy") is a recreational drug of abuse, popular worldwide for its distinctive psychotropic effects. Currently, the therapeutic potential of MDMA in psychotherapy has attracted a lot of interest from the scientific community, despite the multitude of effects that this drug of abuse elicits on the human body. While neuronal effects have been...
Previous preclinical studies have demonstrated that 3,4‐methylenedioxymethamphetamine (MDMA) dose‐dependently increases pro‐social behavior and affiliative vocalizations in male nonhuman primates. As diagnostic criteria for several psychiatric diseases includes deficits in social functioning, examining the conditions under which MDMA selectively increases pro‐social behavior may provide...

3,4‐Methylenedioxymethamphetamine (MDMA) is currently one of the most popular club psychostimulant and hallucinogens. MDMA's primary site of action is in the brain where it produces a “euphoric” feeling, this euphoria comes with a multitude of acute toxicities. In the periphery, MDMA acts as an immunosuppressive agent in the periphery decreasing the robust activity of the adaptive and innate...
BACKGROUND: Synthetic cathinones display overlapping behavioral effects with psychostimulants (e.g., methamphetamine [MA]) and/or entactogens (e.g., 3,4-methylenedioxymethaphetamine [MDMA])-presumably reflecting their dopaminergic and/or serotonergic activity. The discriminative stimulus effects of MDMA thought to be mediated by such activity have been well characterized in rodents but have not...
This review examines the role of trauma in psychiatric morbidity and analogous psychoneurobiological changes. Trauma is a necessary criterion for Post-Traumatic Stress Disorder (PTSD), however, trauma history is highly correlated with a variety of psychiatric conditions. Some evidence suggests that Major Depressive Disorder (MDD) is the most common psychiatric condition that arises following...
Introduction Posttraumatic stress disorder is a prevalent mental health condition with substantial impact on daily functioning that lacks sufficient treatment options. Previous research has led to the designation of 3,4-methylenedioxymethamphetamine (MDMA) as a Breakthrough Therapy for treatment of post-traumatic stress disorder (PTSD) when administered as an adjunct to psychotherapy....

Introduction Post-traumatic stress disorder (PTSD) is often a chronic condition, despite the existence of evidence-based treatment options. Psychotherapy is the designated first line treatment for PTSD, although high rates of psychiatric and medical comorbidity are observed among patients who have undergone treatment. The psychoactive properties of psychedelics may be of particular interest...

Introduction Recently there has been renewal in interest of psychedelic research. Classic psychedelics such as lysergic acid diethylamide (LSD), psilocybin and mescaline act pharmacologically as agonists at the 5-HT2A receptor. The entactogens like methylenedioxymethamphetamine (MDMA), acts as a serotonin, dopamine and noradrenaline agonist. All of these drugs are potential candidates in the...
Background: 3,4-methylenedioxymethamphetamine (MDMA, “ecstasy”) is used both recreationally and therapeutically. Little is known about the factors influencing inter- and intra-individual differences in the acute response to MDMA. Effects of other psychoactive substances have been shown to be critically influenced by personality traits and mood state before intake. Methods: We pooled data from...
Methamphetamine (METH) and 3,4-methylenedioxymethamphetamine (MDMA), amphetamine derivatives widely used as recreational drugs, induce similar neurotoxic effects in mice, including a marked loss of tyrosine hydroxylase (TH) and dopamine transporter (DAT) in the striatum. Although the role of dopamine in these neurotoxic effects is well established and pharmacological studies suggest involvement...
Abstract Aims To determine trends in 3,4 methylenedioxymethamphetamine (MDMA)‐related death rates across Australia, Finland, Portugal and Turkey and to analyse the toxicology and causes of death across countries. Design Analysis of MDMA‐related deaths extracted from a national coronial database in Australia (2001–19) and national forensic toxicology databases in Finland (2001–17), Portugal...
Abstract 3,4-Methylenedioxymethamphetamine (MDMA) is currently being evaluated by the Food and Drug Administration (FDA) for the treatment of post-traumatic stress disorder (PTSD). If MDMA is FDA-approved it will be important to understand what medications may pose a risk of drug–drug interactions. The goal of this study was to evaluate the risks due to MDMA ingestion alone or in combination...
Abstract Methylenedioxymethamphetamine (MDMA) is an amphetamine analogue that preferentially stimulates the release of serotonin (5HT) and results in relatively small increases in synaptic dopamine (DA). The ratio of drug‐stimulated increases in synaptic DA, relative to 5HT, predicts the abuse liability; drugs with higher DA:5HT ratios are more likely to be abused. Nonetheless, MDMA is a drug...
Clinical and preclinical evidence indicates that prenatal exposure to glucocorticoids may induce detrimental effects in the offspring, including reduction in fetal growth and alterations in the CNS. On this basis, the present study investigated whether in utero exposure to high levels of glucocorticoids is a risk factor that may lead to an exacerbation of the central noxious effects induced by...
Nonprofit efforts to develop ±3,4-methylenedioxymethamphetamine (MDMA)-better known as the street drug Ecstasy-as a prescription pharmaceutical provide the opportunity to examine recent theorizations of pharmaceuticals as fluid objects transformed in new informational and material environments. Drawing from ethnographic research, this article interrogates MDMA researchers' own distinction...
P sychedelics have recently gained attention as compounds with therapeutic potential in the treatment of psychiatric disorders.The US Food and Drug Administration (FDA) has granted Breakthrough Therapy Designations for (±)-3,4-methylenedioxymethamphetamine (MDMA) as an adjunct to psychotherapy in severe posttraumatic stress disorder (PTSD) (in 2017) and for the adjunctive use of psilocybin with...
Background: 3,4-methylenedioxymethamphetamine (MDMA) therapy has qualities that make it potentially well suited for patients with addictions, but this has never been explored in a research study. We present data from the Bristol Imperial MDMA in Alcoholism (BIMA) study. This is the first MDMA addiction study, an open-label safety and tolerability proof-of-concept study investigating the...

3,4-Methylenedioxymethamphetamine (MDMA) is an amphetamine derivative that has been shown to produce serotonergic damage in the brains of primates, including humans, and of rats. Tryptophan, the precursor of serotonin, is primarily degraded through the kynurenine (KYN) pathway, producing among others KYN, the main metabolite of this route. KYN has been reported as an endogenous agonist of the...
Prior use of selective serotonin reuptake inhibitors (SSRIs) may reduce the effectiveness of 3,4‐methylenedioxymethamphetamine (MDMA)‐assisted therapy for post‐traumatic stress disorder (PTSD), say researchers of a recent study who noted that MDMA is close to being considered the first psychedelic drug approved to treat PTSD.
Adolescence is a period of profound developmental changes, which run the gamut from behavioral and neural to physiological and hormonal. It is also a time at which there is an increased propensity to engage in risk-taking and impulsive behaviors like drug use. This review examines the human and preclinical literature on adolescent drug use and its consequences, with a focus on dissociatives...
