	(what is this?)

Amfepramone, also known as diethylpropion, is a stimulant drug of the phenethylamine, amphetamine, and cathinone classes that is used as an appetite suppressant.^[4]^[5] It is used in the short-term management of obesity, along with dietary and lifestyle changes.^[4] 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.^[6]

Pharmacology[]

Amfepramone itself lacks any affinity for the monoamine transporters and instead functions as a prodrug to ethcathinone.^[7] 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.^[7] As a result, ethcathinone and amfepramone can essentially be considered a member of the class of drugs known as norepinephrine releasing agents (NRAs).

Chemistry[]

Amfepramone can be synthesized from propiophenone by bromination, followed by reaction with diethylamine.^[8]^[9]

Society and culture[]

Names[]

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.

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.

Recreational use[]

The authors of several studies of amfepramone claim that the substance has a relatively low potential for causing addiction in users.^[11]^[12]^[13]^[14] However, there have been reports of people using this drug recreationally in the UK^{[citation needed]}. Allegedly, recreational users of amfepramone in the UK refer to amfepramone tablets as "tombstones"^{[citation needed]}.
