Ethylamphetamine (Apetinil, Adiparthrol), also known as etilamfetamine or N-ethylamphetamine, is a stimulant drug of the phenethylamine and amphetamine chemical classes. It was invented in the early 1900s and was subsequently used as an anorectic or appetite suppressant in the 1950s,[1] 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.



The molecular structure of ethylamphetamine is analogous to amphetamine's.[Note 1] It is a substituted amphetamine, with an ethyl group on the amphetamine backbone.[Note 2][Note 3]

Recreational use

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, its potency being slightly greater than amphetamine's and lesser than methamphetamine's.[Note 4]

  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.
  4. ^ Ethylamphetamine's higher potency may make its risk of causing abuse, dependence and/or addiction greater compared to amphetamine.
