Bile acids and the gut microbiome are involved in the hyperthermia mediated by 3,4-methylenedioxymethamphetamine (MDMA).

Scientific Reports June 24, 2024 Srishti Rana, Jeremy R Canfield, Christopher S Ward et al. 5 citations

Hyperthermia induced by phenethylamines, such as 3,4-methylenedioxymethamphetamine (MDMA), can lead to life-threatening complications and death. Activation of the sympathetic nervous system and subsequent release of norepinephrine and activation of uncoupling proteins have been demonstrated to be the key mediators of phenethylamine-induced hyperthermia (PIH). Recently, the gut microbiome was...

Influence of adrenalectomy on the gut microbiome and MDMA-induced hyperthermia.

European Journal of Pharmacology April 15, 2023 Amal Aburahma, Srishti Rana, Ray A. Larsen et al. 5 citations

The increased use of the stimulant drug, 3,4-methylenedioxymethamphetamine (MDMA), more commonly known as Ecstasy, Molly or X, has been linked to the development of life-threatening hyperthermia in human and animal models. The current study aimed to investigate the role of the gut-adrenal axis in MDMA-induced hyperthermia by assessing the influence of the acute exogenous supplementation with...

The influence of the host microbiome on 3,4-methylenedioxymethamphetamine (MDMA)-induced hyperthermia and vice versa

Scientific Reports March 13, 2019 Emily Ridge, Sudhan Pachhain, S. Choudhury et al. 25 citations

Hyperthermia induced by 3,4-methylenedioxymethamphetamine (MDMA) can be life-threatening. Here, we investigate the role of the gut microbiome and TGR5 bile acid receptors in MDMA-mediated hyperthermia. Fourteen days prior to treatment with MDMA, male Sprague-Dawley rats were provided water or water treated with antibiotics. Animals that had received antibiotics displayed a reduction in gut...

Effects of ambient temperature on the relative reinforcing strength of MDMA using a choice procedure in monkeys.

Psychopharmacology January 2008 Matthew L Banks, Jon E. Sprague, Paul W Czoty et al.

3,4-Methylenedioxymethamphetamine (MDMA, ecstasy) is frequently used in hot environments, such as rave parties. Studies in laboratory animals have shown that ambient temperature can alter the behavioral and neurochemical effects of MDMA. To examine the influence of ambient temperature on the relative reinforcing strength of MDMA and reinstatement of behavior previously maintained by MDMA is the...

Ambient temperature effects on 3,4-methylenedioxymethamphetamine-induced thermodysregulation and pharmacokinetics in male monkeys.

Drug metabolism and disposition: the biological fate of chemicals October 2007 Matthew L Banks, Jon E. Sprague, David F Kisor et al.

Changes in ambient temperature are known to alter both the hyperthermic and the serotonergic consequences of 3,4-methylenedioxymethamphetamine (MDMA). Metabolism of MDMA has been suggested to be a requisite for these neurotoxic effects, whereas the hyperthermic response is an important contributing variable. The aim of the present study was to investigate the interaction between ambient...

Carvedilol reverses hyperthermia and attenuates rhabdomyolysis induced by 3,4-methylenedioxymethamphetamine (MDMA, Ecstasy) in an animal model*

Critical Care Medicine June 1, 2005 Jon E. Sprague, Petra Moze, David Caden et al. 75 citations

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.

Attenuation of 3,4‐methylenedioxymethamphetamine (MDMA, Ecstasy)‐induced rhabdomyolysis with α1‐ plus β3‐adrenoreceptor antagonists

British Journal of Pharmacology June 1, 2004 Jon E. Sprague, Robert E. Brutcher, Edward Mills et al. 53 citations

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...
