Mexedrone (also known as 4-MMC-MeO) is a stimulant and an entactogen drug of the cathinone class that has been sold online as a designer drug.[1][2][3][4] It is the alpha-methoxy derivative of Mephedrone.


Mexedrone acts as a weak serotonin–norepinephrine–dopamine reuptake inhibitor (SNDRI) with IC50 values of 5289 nM, 8869 nM and 6844 nM, respectively, as well as a weak serotonin releasing agent (SRA) with an EC50 value of 2525 nM.[5]

Legal status

Mexedrone is illegal in Sweden as of January 26, 2016[6] as well as Japan as of August 24, 2016.[7]
