amfepramone amfepramone amfepramone, also known as diethylpropion, is a stimulant drug of the phenethylamine, amphetamine, and cathinone classes that is used as an appetite suppressant. it is used in the short-term management of obesity, along with dietary and lifestyle changes. amfepramone has a similar chemical structure 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. amfepramoneclinical datatrade namestenuate, tepanil, nobesine, othersother namesdiethylpropion, diethylcathinoneahfs/drugs.commonographmedlineplusa682037license data us dailymed: diethylpropion pregnancycategory au: b2 routes ofadministrationby mouthatc codea08aa03 (who) legal statuslegal status au: s4 (prescription only) ca: schedule g (cdsa iv) de: prescription only (anlage iii for higher doses) uk: class c us: schedule iv eu: rx-only pharmacokinetic dataelimination half-life4-6 hours (metabolites)excretionurine (>75%)identifiers iupac name (rs)-2-diethylamino-1-phenylpropan-1-one cas number134-80-5 ypubchem cid7029iuphar/bps7161drugbankdb00937 ychemspider6762 yunii19v2pl39ngkeggd07444 nchebichebi:4530 ychemblchembl1194666 ncomptox dashboard (epa)dtxsid6022929 echa infocard100.001.836 chemical and physical dataformulac13h19nomolar mass205.301 g·mol−13d model (jsmol)interactive imagechiralityracemic mixture smiles o=c(c1ccccc1)c(n(cc)cc)c inchi inchi=1s/c13h19no/c1-4-14(5-2)11(3)13(15)12-9-7-6-8-10-12/h6-11h,4-5h2,1-3h3 ykey:xxepppiwzficoj-uhfffaoysa-n y ny (what is this?) (verify) pharmacology 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 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. society and culture names another medically-utilized name is diethylpropion (british approved name (ban) and australian approved name (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. legal status amfepramone is classified as a schedule iv controlled substance in the united states. in the uk amfepramone is a class c drug and as a medicine, it is a schedule 3 controlled drug which requires safe custody. as of june 2022, the safety committee of the european medicines agency (ema) recommends the withdrawal of marketing authorizations for amfepramone. recreational use the authors of several studies of amfepramone claim that the substance has a relatively low potential for causing addiction in users.
