Pharmacology/ Kinetics

MDMAcausesthereleaseofseveralneurotransmitters,primarilyserotonin(5HT),butalsodopamine(DA),andnorepinephrine(NE).Itinhibitsthereuptakeofserotoninandhasthepotential,withchronicuse,todestroyserotoninnerveterminals.Theseneurotransmittersareinvolvedinmoodregulation,thermoregulation,sleepcontrol,appetite,reward,andtheautonomicnervoussystem. MDMAisusuallyformulatedasatabletfor

ingestion,althoughitcanbesnorted,smoked,orinjected.Serumhalf-livesgenerallyrangefrom7to10hoursinacidurineto16to31hoursinalkalineurine.2Thetypicalhalf-lifeis8hoursandatypical“high”lasts3to5hours.

Adverse Effects Adverseeffectsincludejawclenching,lossofappetite,trismus,bruxism,nausea,drymouth,confusion,sweating,headache,fatigue,insomnia,constantrestlessmovementsofthelegsandmuscleaches.Majoradverseeffectsincludehypertension,tachycardia, (cont. on pg. 2)
