Amfepramone 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. 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. As a result, ethcathinone and amfepramone can essentially be considered norepinephrine releasing agents (NRAs). Amfepramone is believed to have relatively low abuse potential. 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.
