The contribution of exercise to hyperthermia mediated by MDMA is not known. We recently showed that inhibiting the dorsomedial hypothalamus (DMH) attenuated spontaneous locomotion and hyperthermia and prevented deaths in rats given MDMA in a warm environment. The goal of this study was to confirm that restoring locomotion through a treadmill would reverse these effects thereby confirming that...

Acute and chronic complications from the substituted amphetamine 3,4-methylenedioxymethamphetamine (MDMA) are linked to activation of the hypothalamic-pituitary-adrenal (HPA) axis. How MDMA activates the HPA axis is not known. HPA responses to stress are known to be mediated through the paraventricular (PVH) hypothalamus and to involve serotonin-1a (5-HT1A) receptors. We sought to determine if...

When given systemically to rats and humans, the drug of abuse 3,4 methylenedioxymethamphetamine (ecstasy, MDMA) elicits hyperthermia, hyperactivity, tachycardia, and hypertension. Chemically stimulating the dorsomedial hypothalamus (DMH), a brain region known to be involved in thermoregulation and in stress responses, causes similar effects. We therefore tested the hypothesis that neuronal...

These data show that alpha1 and beta3-adrenergic receptors may contribute to the mediation of MDMA-induced hyperthermia and that drugs targeting these receptors, such as carvedilol, warrant further investigation as novel therapies for the treatment of psychostimulant-induced hyperthermia and its sequelae.

Studies were designed to examine the effects of α 1 ( α 1 AR)‐ plus β 3 ‐adrenoreceptor ( β 3 AR) antagonists on 3,4‐methylenedioxymethamphetamine (MDMA, Ecstasy)‐induced hyperthermia and measures of rhabdomyolysis (creatine kinase (CK)) and renal function (blood urea nitrogen (BUN) and serum creatinine (sCr)) in male Sprague–Dawley rats. MDMA (40 mg kg −1 , s.c.) induced a rapid and robust...
