Episode 84: MDMA: Why Does Toxicity Differ Between People?

This week on The Tox Lab, we’re discussing MDMA, examining its pharmacology, toxicity, and the factors that influence individual susceptibility to harm.We begin by exploring how MDMA works, focusing on its effects on serotonin release, reuptake, and signalling, and the pharmacological mechanisms responsible for its desired effects and adverse reactions.We then examine a case of severe MDMA toxicity resulting in hyperthermia and multi-organ failure, discussing the clinical features, management, and the toxicological mechanisms underlying these life-threatening complications.Finally, we turn to the role of the polymorphic enzyme CYP2D6 in MDMA metabolism, examining how genetic variation and MDMA-induced inhibition of CYP2D6 can influence drug concentrations, toxicity, and the risks associated with repeat dosing and drug interactions.Join us as we examine the pharmacology, clinical toxicology, and pharmacogenetics of MDMA, and consider what these findings mean for understanding both its desired effects and its potential harms.Hope you enjoy!Links to the papers we discussed:https://pmc.ncbi.nlm.nih.gov/articles/PMC11470468/pdf/main.pdfhttps://pmc.ncbi.nlm.nih.gov/articles/PMC3495276/pdf/fgene-03-00235.pdfhttps://analyticalsciencejournals.onlinelibrary.wiley.com/doi/10.1002/dta.2605 Disclaimer: All opinions are our own.Find us on instagram: @the_tox_labEmail us here: [email protected] out our new website: https://thetoxlab.co.uk/ Support us here: https://buymeacoffee.com/thetoxlab
