MDMA has properties that may make it attractive for psychotherapy, although many of its effects are potentially problematic. These contrasting effects will be critically reviewed in order to assess whether MDMA could be safe for clinical usage. Early studies from the 1980s noted that MDMA was an entactogen, engendering feelings of love and warmth. However, negative experiences can also occur with MDMA since it is not selective in the thoughts or emotions it releases. This unpredictability in the psychological material released is similar to another serotonergic drug, LSD. Acute MDMA has powerful neurohormonal effects, increasing cortisol, oxytocin, testosterone, and other hormone levels. The release of oxytocin may facilitate psychotherapy, whereas cortisol may increase stress and be counterproductive. MDMA administration is followed by a period of neurochemical recovery, when low serotonin levels are often accompanied by lethargy and depression. Regular usage can also lead to serotonergic neurotoxicity, memory problems, and other psychobiological problems. Proponents of MDMA-assisted therapy state that it should only be used for reactive disorders (such as PTSD) since it can exacerbate distress in those with a prior psychiatric history. Overall, many issues need to be considered when debating the relative benefits and dangers of using MDMA for psychotherapy.

Besides the well-known roles of oxytocin on birth, maternal bonding, and lactation, recent evidence shows that this hypothalamic hormone possesses cardioprotective, anti-inflammatory and parasympathetic neuromodulation properties. In this study, we explore the heart rate fluctuations (HRF) in an endotoxemic rodent model that was accompanied by the administration of exogenous oxytocin. The assessment of HRF has been widely used as an indirect measure of the cardiac autonomic function. In this context, adult male Dark Agouti rats were equipped with a telemetric transmitter to continuously and remotely measure the electrocardiogram, temperature, and locomotion. In a between-subjects experimental design, rats received the following peripheral treatment: saline solution as a vehicle (V); lipopolysaccharide (LPS); oxytocin (Ox); lipopolysaccharide + oxytocin (LPS+Ox). Linear and non-linear parameters of HRF were estimated starting 3h before to 24h after treatments. Our results showed that exogenous oxytocin does not modify by itself the HRF of oxytocin-treated rats in comparison to vehicle-treated rats. However, in animals undergoing endotoxemia it: a) provokes a less anticorrelated pattern in HRF, b) decreased mean heart rate, c) moderated the magnitude and duration of the LPS-induced hyperthermia, and d) increased locomotion, up to 6h after the LPS injection. The less anticorrelated pattern in the HRF and decreased mean heart rate may reflect a cardiac pacemaker coupling with cholinergic influences mediated by oxytocin during LPS-induced endotoxemia. Finally, the anti-lethargic and long-term temperature moderating effects of the administration of oxytocin during endotoxemia could be a consequence of the systemic anti-inflammatory properties of oxytocin.
