3,4-Ethylenedioxy-N-methylamphetamine (EDMA) is a psychoactive drug of the phenethylamine, amphetamine, and EDxx families. [1] [2] It is an analogue of MDMA where the methylenedioxy ring has been replaced by an ethylenedioxy ring. [1] [2] EDMA was first synthesized by Alexander Shulgin. [1] In his book PiHKAL , the dose is listed as 150 to 250 mg and the duration as 3 to 5 hours. [1] According to Shulgin, EDMA produces only mild effects that included paresthesia, nystagmus, a dozing state, hypnogogic imagery, and colored letters in the peripheral visual field. [1]
It has been found that EDMA acts as a non-neurotoxic serotonin releasing agent with moderately diminished potency relative to MDMA, and with negligible effects on dopamine release. [2] However, subsequent research found that EMDA is a serotonin–norepinephrine–dopamine releasing agent (SNDRA) with EC50 values of 117 nM for serotonin release, 325 nM for norepinephrine release, and 597 nM for dopamine release in rat brain synaptosomes. [3] Compared to MDMA, EDMA was about half as potent as a serotonin releaser, 4.5-fold less potent as a norepinephrine releaser, and 8-fold less potent as a dopamine releaser. [3] The activities of the individual enantiomers of EDMA have also been assessed. [3]
