Metamfepramone (INN, also known as dimethylcathinone, dimethylpropion, and dimepropion (BAN)) is a stimulant drug of the phenethylamine, and cathinone chemical classes.

Dimethylcathinone was evaluated as an appetite suppressant and for the treatment of hypotension, but was never widely marketed.

[4] It has also been found to be about 1.6 times less potent than methcathinone, making it roughly equipotent to cathinone itself.

[5] In the United States, metamfepramone (N,N-Dimethyl-cathinone) is considered a Schedule I controlled substance as a positional isomer of mephedrone.
