Amfepramone (INN)^{[note 1]} is a stimulant drug of the phenethylamine, amphetamine, and cathinone classes that is used as an appetite suppressant.^[2]^[3] It is used in the short-term management of obesity, along with dietary and lifestyle changes.^[2] Amfepramone is most closely chemically related to the antidepressant and smoking cessation aid bupropion (previously called amfebutamone), which has also been developed as a weight-loss medicine when in a combination product with naltrexone.^[4]

Pharmacology

Amfepramone itself lacks any affinity for the monoamine transporters and instead functions as a prodrug to ethcathinone.^[5] 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.^[5] As a result, ethcathinone and amfepramone can essentially be considered a member of the class of drugs known as norepinephrine releasing agents (NRAs).

Abuse

Amfepramone is believed to have relatively low abuse potential.^[6]^[7]^[8]^[9] but recently there have been reports of teens and adults in the UK abusing this drug, known as "tombstones" to the abusers.

Legality

Amfepramone is classified as a Schedule IV controlled substance in the United States. It is also a Schedule IV controlled substance in Canada. In the UK Amfepramone is a class C drug ^[10] and as a medicine, it is a Schedule 3 Controlled Drug which requires safe custody. It's not US FDA approved.

Chemistry

Propiophenone is brominated to produce α-bromopropiophenone.
This is reacted with diethylamine to yield the product, diethylpropion.^[11]^[12]

Notes

↑ Another medically-utilized name is diethylpropion (BAN and AAN). Chemical names include: α-methyl-β-keto-N,N-diethylphenethylamine, N,N-diethyl-β-ketoamphetamine and N,N-diethylcathinone. Brand names include: Anorex, Linea, Nobesine, Prefamone, Regenon, Tepanil and Tenuate.
