phenethylamine class that is used in the treatment of attention deficit
hyperactivity disorder and narcolepsy. It is also used as a performance
enhancer and nootropic, and recreationally as an aphrodisiac and
euphoriant. Amphetamine increases neurotransmitter activity in the
brain, with its most pronounced effects on norepinephrine and dopamine.
At therapeutic doses, this causes emotional and cognitive effects such
as euphoria, change in libido, increased wakefulness, and improved
cognitive control. It induces physical effects such as decreased
reaction time, fatigue resistance, and increased muscle strength.
Amphetamine exists as two enantiomers, levoamphetamine and
dextroamphetamine, and normally refers to an equal parts mixture of the
two enantiomers in its free base form. It is a prescription medication
in many countries, and unauthorized possession and distribution of
amphetamine are often tightly controlled due to the significant health
risks associated with uncontrolled or heavy use.
