Rankings / Cognitive — Prescription Stimulants
Methylphenidate / phenidate stimulants
Cognitive · Prescription stimulant / dopamine-norepinephrine reuptake inhibitor
Tier C
What this is
WADA coverage: methylphenidate, ethylphenidate, 4-fluoromethylphenidate and methylnaphthidate. Added because this stimulant family was not represented by the existing amphetamine/modafinil rows.
Mechanism
Methylphenidate and analogs increase catecholamine signaling, improving ADHD symptoms and wakeful task focus; healthy-user cognitive enhancement is smaller and context-dependent.
Dose & route
Clinical ADHD dosing varies by formulation; no enhancement dose
