Examining the role of oxytocin in the interoceptive effects of 3,4‐methylenedioxymethamphetamine (MDMA, ‘ecstasy’) using a drug discrimination paradigm in the rat

TLDR
The results of this study implicate oxytocin receptor activation as a key MDMA‐specific interoceptive cue in male and female rats and support the conclusion that this is one of the features of MDMA's subjective effects that distinguishes it from AMP.

Acute Prosocial Effects of Oxytocin and Vasopressin When Given Alone or in Combination with 3,4-Methylenedioxymethamphetamine in Rats: Involvement of the V1A Receptor

TLDR
Results show for the first time acute prosocial effects of peripherally injected OT and AVP in laboratory rats, and suggest a commonality of action of OT, AVP, and MDMA in stimulating social behavior that involves V1ARs.

Aromatic Bromination Abolishes the Psychomotor Features and Pro-social Responses of MDMA (“Ecstasy”) in Rats and Preserves Affinity for the Serotonin Transporter (SERT)

TLDR
2-Br-4,5-MDMA lacks all key MDMA-like behavioral responses in rats, including hyperlocomotion, enhanced active avoidance conditioning responses and increased social interaction, indicating that aromatic bromination at C(2) modulates the pharmacodynamic properties of the substrate MDMA, yielding a citalopram-like compound.

Effects of ±3,4-Methylenedioxymethamphetamine (MDMA) Administration on Social Emotional Processing in Humans

TLDR
The effects of MDMA on the identification of others’ emotional expressions, and on feelings associated with the ‘empathogenic’ profile are examined.

3,4-Methylenedioxymethamphetamine Increases Affiliative Behaviors in Squirrel Monkeys in a Serotonin 2A Receptor-Dependent Manner

TLDR
Nonhuman primates show MDMA-specific increases in affiliative social behaviors following MDMA administration, in concordance with human and rodent studies, and MDMA-induced increases in social behaviors are 5-HT2A, but not 5- HT1A, receptor dependent.

Increased oxytocin concentrations and prosocial feelings in humans after ecstasy (3,4-methylenedioxymethamphetamine) administration

TLDR
MDMA induces oxytocin release in humans, which may be involved in the characteristic prosocial effects of ecstasy, in a double blind, randomized, crossover, and placebo-controlled study in 15 healthy volunteers.

Investigation of serotonin-1A receptor function in the human psychopharmacology of MDMA

TLDR
The findings suggest that MDMA differentially affects higher cognitive functions, but does not support the hypothesis from animal studies, that some of the MDMA effects are causally mediated through action at the 5-HT1A receptor system.

Residual social, memory and oxytocin-related changes in rats following repeated exposure to γ-hydroxybutyrate (GHB), 3,4-methylenedioxymethamphetamine (MDMA) or their combination

TLDR
GHB treatment caused residual impairments in memory and social behaviour and increases in anxiety, paralleling the lasting adverse effects of MDMA and this may be related to the long-term social interaction deficiencies caused by both drugs.

The effect of 3,4‐methylenedioxymethamphetamine (MDMA, ?ecstasy?) and its metabolites on neurohypophysial hormone release from the isolated rat hypothalamus

TLDR
MDMA and its metabolites can stimulate both oxytocin and vasopressin release in vitro, the response being dose dependent for each drug with HMMA being the most potent.
