Etilamfetamine, also known as N-ethylamphetamine and formerly sold under the brand names Apetinil and Adiparthrol, is a stimulant drug of the amphetamine family. It was invented in the early 20th century and was subsequently used as an anorectic or appetite suppressant in the 1950s,[2] but was not as commonly used as other amphetamines such as amphetamine, methamphetamine, and benzphetamine, and was largely discontinued once newer drugs such as phenmetrazine were introduced.

Pharmacology

edit

Ethylamphetamine is a potent dopamine releasing agent in vitro, with an EC50Tooltip half-maximal effective concentration of 88.5 nM.[3] This is about 10-fold lower than the EC50 of amphetamine.[3] The EC50 values of ethylamphetamine for induction of norepinephrine and serotonin release were not reported.[3] Ethylamphetamine can also be N-dealkylated into amphetamine (5–18% excreted in urine after 24 hours).[4]

Chemistry

edit

The molecular structure of ethylamphetamine is analogous to methamphetamine, with an ethyl group in place of the methyl group.[Note 1] It can also be considered a substituted amphetamine, with an ethyl group on the amphetamine backbone.[Note 2][Note 3]

Recreational use

edit

Ethylamphetamine can be used as a recreational drug and, while its prevalence is less than amphetamine's, it is still encountered as a substance taken for recreational purposes.

Ethylamphetamine produces effects similar to amphetamine and methamphetamine, though it is of weaker potency.[citation needed] At equipotent dosage, ethylamphetamine is subjectively less euphorigenic.[citation needed]

Notes

edit
  1. ^ Amphetamine is a substituted phenethylamine with a methyl group at RA position.
  2. ^ The ethyl group of ethylamphetamine is at RN position, hence the name N-ethylamphetamine.
  3. ^ Ethylamphetamine is structurally similar to N-methylamphetamine (methamphetamine), the ethyl group being replaced in methamphetamine with a methyl group.
