Diethylpropion is a sympathomimetic stimulant drug marketed as an appetite suppressant. Chemically, it is the N,N-diethyl analog of cathinone. Its mechanism of action is similar to other appetite suppressants such as sibutramine, phentermine and dextroamphetamine.
- Mechanism of action
Diethylpropion is an amphetamine that stimulates neurons to release or maintain high levels of a particular group of neurotransmitters known as catecholamines; these include dopamine and norepinephrine. High levels of these catecholamines tend to suppress hunger signals and appetite. Diethylpropion (through catecholamine elevation) may also indirectly affect leptin levels in the brain. It is theorized that diethylpropion can raise levels of leptin which signal satiety. It is also theorized that increased levels of the catecholamines are partially responsible for halting another chemical messenger known as neuropeptide Y. This peptide initiates eating, decreases energy expenditure, and increases fat storage.
Target Actions Organism ASodium-dependent noradrenaline transporter inhibitorHumans ASodium-dependent dopamine transporter inhibitorHumans - Absorption
Diethylpropion is rapidly absorbed from the GI tract after oral administration.

Not Available
- Protein binding

- Metabolism
Extensively metabolized through a complex pathway of biotransformation involving N-dealkylation and reduction. Many of these metabolites are biologically active and may participate in the therapeutic action of diethylpropion.
- Route of elimination
Diethylpropion is rapidly absorbed from the GI tract after oral administration and is extensively metabolized through a complex pathway of biotransformation involving N-dealkylation and reduction. Diethylpropion and/or its active metabolites are believed to cross the blood-brain barrier and the placenta. Diethylpropion and its metabolites are excreted mainly by the kidney.
- Half-life
Using a phosphorescence assay that is specific for basic compounds containing benzoyl group, the plasma half-life of the aminoketone metabolites is estimated to be between 4 to 6 hours.

interactions in your software1,2-Benzodiazepine The risk or severity of adverse effects can be increased when Diethylpropion is combined with 1,2-Benzodiazepine. Abaloparatide The risk or severity of adverse effects can be increased when Diethylpropion is combined with Abaloparatide. Acebutolol The therapeutic efficacy of Acebutolol can be decreased when used in combination with Diethylpropion. Aceclofenac The risk or severity of hypertension can be increased when Diethylpropion is combined with Aceclofenac. Acemetacin The risk or severity of hypertension can be increased when Diethylpropion is combined with Acemetacin. Acetazolamide Acetazolamide may decrease the excretion rate of Diethylpropion which could result in a higher serum level. Acetophenazine Acetophenazine may decrease the stimulatory activities of Diethylpropion. Acetylsalicylic acid The risk or severity of hypertension can be increased when Diethylpropion is combined with Acetylsalicylic acid. Aclidinium Diethylpropion may increase the central nervous system depressant (CNS depressant) activities of Aclidinium.
