Interaction Details
Amphetamine is classified as belonging to the following category: Monoamine Oxidase Inhibitors (Maois)
Theoretically, taking phenethylamine concomitantly with MAOIs may increase adverse effects.
In humans, phenethylamine is oxidized by MAO-B to form the inactive metabolite phenylacetic acid. Animal research shows that administering an MAOI prior to phenethylamine increases the amphetamine-like effects of phenethylamine. However, low-quality clinical research has used phenethylamine with selegiline, an MAOI, with apparent safety.

Phenethylamine (pea) Overview
Phenethylamine (PEA) is a monoamine alkaloid present in various sources, including plants, bacteria, fungi, and animals, including humans. It is also found in certain foods like chocolate and eggs. This compound is synthesized in the body through the decarboxylation of the amino acid L-phenylalanine. Within the central nervous system, PEA serves as both a neuromodulator and neurotransmitter, playing a crucial role in neuronal signaling. Phenethylamine is available as a dietary supplement and is used for potential cognitive and mood-enhancing effects, although further research is needed to fully understand its effects in these regards.
Amphetamine Overview
-
Amphetamine (Adzenys ER, Adzenys XR, Dyanavel XR, Evekeo, Evekeo ODT, others) is used as part of a treatment program to control symptoms of attention deficit hyperactivity disorder (ADHD; more difficulty focusing, controlling actions, and remaining still or quiet than other people who are the same age) in adults and children. Amphetamine (Evekeo, others) is also used to treat narcolepsy (a sleep disorder that causes excessive daytime sleepiness and sudden attacks of sleep). Amphetamine (Evekeo, others) is also used for a limited period of time (a few weeks) along with a reduced calorie diet and an exercise plan for weight loss in obese people unable to lose weight. Amphetamine is in a class of medications called central nervous system stimulants. It works by changing the amounts of certain natural substances in the brain.
