Amfepramone (INN, other names diethylcathinone and diethylpropion, trade names Anorex, Linea, Nobesine, Prefamone, Regenon, Tepanil, Tenuate), is a stimulant drug of the phenethylamine, amphetamine, and cathinone chemical classes that is used as an appetite suppressant.


Amfepramone itself lacks any affinity for the monoamine transporters and instead functions as a prodrug to ethcathinone.[1] Ethcathinone (and therefore amfepramone as well) is a very weak dopaminergic and serotonergic, and is approximately 10x and 20x stronger on norepinephrine in comparison, respectively.[1] As a result, ethcathinone and amfepramone can essentially be considered norepinephrine releasing agents (NRAs).


Amfepramone is believed to have relatively low abuse potential.,[2][3][4][5] but recently there have been reports of teens and adults in the UK abusing this drug, known as "tombstones" to the abusers.


Amfepramone is classified as a Schedule IV controlled substance in the United States. In the UK Amfepramone is a class C drug [6] and as a medicine, it is a Schedule 3 Controlled Drug which requires safe custody.


  1. Propiophenone is brominated to produce α-bromopropiophenone.
  2. This is reacted with diethylamine to yield the product, diethylpropion.[7][8]
