A neurotransmitter whose extracellular availability is influenced by dopamine transporters. Increased signaling is not a universal benefit.
Each relationship keeps its participants and their roles together. Source details explain what the connection supports.
Acute exposure in healthy volunteers
Limitation Mechanistic imaging does not measure clinical response.
Methylphenidate · Sourced draftHealthy male participants in an acute PET experiment
Limitation Target occupancy is not a clinical outcome and the selected sample limits generalization.
Modafinil · Sourced draftOral administration produced transporter occupancy in a human PET study.
Acute PET findings in healthy men; target occupancy is distinct from a clinical outcome.
Tagged articles and participants in the relationships above. A shared tag alone does not establish a causal effect.
A stimulant medicine with formulation-dependent delivery. ADHD treatment findings and attention-task results should retain their population and exposure context.
Sourced draftWake-promoting medicineA wake-promoting medicine studied in diagnosed sleep disorders. Measured wakefulness, felt alertness and everyday performance are different outcomes.
Sourced draftSupporting reading for this original editorial definition. Independent editorial review has not been recorded.
Directly measured dopamine transporter occupancy after oral methylphenidate.
Limitation Small selected sample and a mechanistic endpoint.
Funding / disclosures Not assessed in this draft.
Source in MethylphenidateMeasured dopamine transporter occupancy and changes in extracellular dopamine.
Limitation Small male-only mechanistic study; cannot establish general cognitive efficacy.
Funding / disclosures NIH and other research support listed in the publication record.
