Safety pharmacology of acute MDMA administration in healthy subjects

Journal of Psychopharmacology February 21, 2017 Patrick Vizeli, Matthias E. Liechti 142 citations

3,4-Methylenedioxymethamphetamine (MDMA; ecstasy) is being investigated in MDMA-assisted psychotherapy. The present study characterized the safety pharmacology of single-dose administrations of MDMA (75 or 125 mg) using data from nine double-blind, placebo-controlled, crossover studies performed in the same laboratory in a total of 166 healthy subjects. The duration of the subjective effects...

The combined effects of 3,4-methylenedioxymethamphetamine (MDMA) and selected substituted methcathinones on measures of neurotoxicity

Neurotoxicology and Teratology February 16, 2017 N. Miner, J. O'Callaghan, T. Phillips et al. 25 citations

The rise in popularity of substituted methcathinones (aka “bath salts”) has increased the focus on their neurotoxic effects. Two commonly abused methcathinones, 3,4-methylenedioxymethcathinone (methylone, MDMC) and 3,4-methylenedioxypyrovalerone (MDPV), are often concomitantly ingested with the illicit drug 3,4-methylenedioxymethamphetamine (MDMA). To examine potential neurotoxic effects of...

Cognitive and behavioural effects induced by social stress plus MDMA administration in mice.

Behavioural Brain Research February 15, 2017 María P García-Pardo, Concepción Roger-Sánchez, Marta Rodríguez‐arias et al.

Adverse life experiences such as social stress may make an individual more vulnerable to drug addiction and mental disorders associated with drug consumption. The present work aimed to evaluate the effects of stress induced by acute social defeat combined with the administration of 3,4-methylenedioxymethamphetamine (MDMA) on depression-like behaviour, memory function and motor response to drug...

Altered Insula Connectivity under MDMA.

Neuropsychopharmacology February 14, 2017 Ishan C Walpola, Timothy Nest, Leor Roseman et al. 50 citations

Recent work with noninvasive human brain imaging has started to investigate the effects of 3,4-methylenedioxymethamphetamine (MDMA) on large-scale patterns of brain activity. MDMA, a potent monoamine-releaser with particularly pronounced serotonin- releasing properties, has unique subjective effects that include: marked positive mood, pleasant/unusual bodily sensations and pro-social, empathic...

Repeated MDMA administration increases MDMA-produced locomotor activity and facilitates the acquisition of MDMA self-administration: role of dopamine D2 receptor mechanisms.

Psychopharmacology February 10, 2017 Ross Van de Wetering, Susan Schenk

Rationale: Repeated exposure to ±3, 4-methylenedioxymethamphetamine (MDMA) produces sensitization to MDMA-produced hyperactivity, but the mechanisms underlying the development of this sensitized response or the relationship to the reinforcing effects of MDMA is unknown. Objectives: This study determined the effect of a sensitizing regimen of MDMA exposure on the acquisition of MDMA...

Evaluation of the Ecstasy influence on tramadol and its main metabolite plasma concentration in rats

Drug Metabolism and Personalized Therapy January 26, 2017 Bardia Jamali, Behjat Sheikholeslami, Yalda Hosseinzadeh Ardakani et al. 6 citations

AbstractBackground:Tramadol is prone to be abused alone, or in combination with 3,4-methylenedioxymethamphetamine (MDMA, Ecstasy). It was reported that 95% of people with a history of substance abuse in the United States used tramadol in 2004. According to the WHO report in 2016, there was a growing number of tramadol abusers alone or in combination with psychoactive substances such as MDMA in...

Interspecies In Vitro Evaluation of Stereoselective Protein Binding for 3,4-Methylenedioxymethamphetamine

Journal of Chemistry 2017 Wan Raihana Wan Aasim, Soo Choon Tan, Siew Hua Gan

Abuse of 3,4-methylenedioxymethamphetamine (MDMA) is becoming more common worldwide. To date, there is no information available on stereoselectivity of MDMA protein binding in humans, rats, and mice. Since stereoselectivity plays an important role in MDMA’s pharmacokinetics and pharmacodynamics, in this study we investigated its stereoselectivity in protein binding. The stereoselective protein...

Navigating intimacy with ecstasy: The emotional, spatial and boundaried dynamics of couples’ MDMA experiences

Research Open 2017 Katie Anderson

MDMA (3,4-methylenedioxy-methamphetamine or ‘ecstasy’) is well-known for its empathic and sociable effects (Bogt, Engels, Hibbel & Van Wel, 2002). Indeed, there is a body of work that discusses the role the drug plays in social bonding (Beck & Rosenbaum, 1998; Duff, 2008; Farrugia, 2015; Hinchliff, 2001; Solowij, Hall & Lee, 1992). However, there has been extremely limited research looking at...

Potential use of cerebrospinal fluid serotonin level as a marker of neuronal injury after exposure to 3 , 4-Methylenedioxymethamphetamine

2017 F. H. Zakaria, Norhafidah Abu, Nasir Mohamad

he trend of drug use has changed tremendously in this millennium (Adnan et al., 2014). Over the past decade, opioids are among the primary drug of abuse in worldwide. However the trend towards using amphetamine-type stimulant (ATS) is notably increasing lately. Amphetamine-type stimulants are a group of drugs consisting mainly of amphetamine and metamphetamine; these include methcathinone,...

There's something about Molly: The underresearched yet popular powder form of ecstasy in the United States.

Substance Abuse 2017 Joseph J Palamar

Molly has been the street name for powder or crystalline ecstasy (3,4-methylenedioxymethamphetamine [MDMA]) in the United States since the early 2000s; however, few studies have examined Molly use or included Molly in the definition of ecstasy/MDMA. Prevalence of self-reported ecstasy use is being underreported on surveys due to the lack of inclusion of "Molly," although Molly is often so...
