Diethylpropion
Home >> Diethylpropion >> Drug Details
Diethylcathinone (also called Diethylpropion and Amfepramone), is a sympathomimetic stimulant drug marketed as an appetite suppressant. It is sold under the brand name Tenuate or Tenuate Dospan, and may also be known as Amfepramone. The popular antidepressant, bupropion (Wellbutrin) is an analogue of this chemical. Both diethylpropion and bupropion have a stimulant effect on the central nervous system.
Pharmacology
Diethylpropion is a prodrug.[1] It does not become bioactive until one of the N-ethyl groups in the chemical structure has become dealkylated in vivo.[1]
(Di)ethylpropion is quite a weak dopaminergic this is in contrast to other monoaminergic based appetite suppressants such as sibutramine, phentermine and dextroamphetamine.
Apparently, it has been found to be potentially neurotoxic in that it causes long-term depletions of 5-HT similar to MDMA.[2] This is somewhat unexpected since neither diethylpropion nor ethylpropion are serotonin releasers.[1] Additionally, ethylpropion only weakly interacts with the SERT (Ki >2000nM) whereas diethypropion is completely active at this transporter.[1]

Chemically, it is the N,N-diethyl homologue of cathinone and dimethylcathinone.
Diethylpropion is manufactured in 25 mg tablets and 75 mg controlled-release tablets (Tenuate, Tepanil Ten-Tab).
Diethylpropion is classified as a Schedule IV controlled substance in the United States.
It is also used in the treatment of migraine (off-label).
