In head-to-head trials, clinicians' ratings favored amphetamines over modafinil, atomoxetine, and methylphenidate
in children, adolescents, and adults.

led to modest improvements in ADHD symptoms, general behaviour, and quality of life.
The Rational Use of Medicines and the Methylphenidate
effectively reduces the amount of MAO degradation of dopamine in the presynaptic terminal by blocking dopamine reuptake - this reduces the amount of H2O2 released (but dopamine can still be degraded in the extracellular synapse and it's unclear if this also does damage).
(13) in 2013 reported that 11.0% of medical students from four medical schools in the Chicago area indicated use of cognitive enhancers of which 41.0% used methylphenidate
. In 2015, Cohen et al.
proved superior to placebo: Those in the groups that received the medication in addition to their psychological intervention had a mean 3-month ADHD Index score that was 1.7 points lower than those on placebo (JAMA Psychiatry.
Because the site of action of methylphenidate
is the DaT, imaging this component of the striatal dopaminergic synapse has been an area of intense investigation in ADHD.
A third study, also from Denmark, identified 240 pregnancies with a prescription dispensed for methylphenidate
in the first trimester and linked them to live birth outcomes between 2005 and 2012.
Prescriptions for methylphenidate
drugs, including Ritalin, have been steadily increasing, according to the Care Quality Commission's (CQC) annual report on controlled drugs.
