Targets / mechanism

• dopamine transporter inhibition
• norepinephrine transporter inhibition
• ADHD stimulant therapy

Optimization domains

• ADHD
• narcolepsy
• wakefulness
• stimulant
• cognition
• cardiovascular

Research basis

• Methylphenidate is a labelled ADHD/narcolepsy stimulant and a common comparator to amphetamine-class agents in adult ADHD evidence reviews.
• It is mechanistically distinct from amphetamine releasers, making it useful for stimulant rotation/comparison discussions.

Limits, risks, and missing evidence

• It still carries stimulant risks: misuse/addiction, insomnia, anxiety, appetite/weight effects, BP/HR increases, and rare serious cardiovascular or psychiatric reactions.
• Individual response differences do not make unsupervised rotation or stacking benign.

Risk flags

• controlled substance
• misuse addiction
• stimulant
• blood pressure
• tachycardia
• insomnia
• anxiety panic
• psychosis mania
• cardiac screening
