Question: what is the difference between dextroamphetamine and levoamphetamine?
Answer: Levoamphetamine is more biased toward promoting norepinephrine release than Dexedrine (dextroamphetamine). Norepinephrine activates the sympathetic nervous system or the fight-or-flight response. ... Because Adderall contains both levo and dextro, Dexedrine is considered more potent overall.
