Levoamphetamine

Levoamphetamine (also levamfetamine, (R)-amphetamine or (−)-amphethamine) is a psychostimulant known to increase wakefulness and focus in association with decreased appetite and fatigue. Levoamphetamine is the levorotatory stereoisomer of the amphetamine molecule. It possesses much weaker dopaminergic activity than the dextrorotary isomer (dextroamphetamine) and acts as a selective releasing agent of norepinephrine, similarly to levomethamphetamine.
