My mission here at CorePsych is simple: Use stimulant medications precisely. If they don't work predictably it's highly likely that your body is influencing the way medications are metabolized.
Prozac and Paxil significantly block the metabolism, the breakdown, the effective use of amphetamine products. The results: crazy but quite predictable drug interactions.
Emerging research also implicates the neurotransmitter glutamate in the development of ADHD, likely due to its interaction with dopamine and norepinephrine.
