Methylphenidate (Ritalin®) is an increasingly used medication in the treatment of attention-deficit hyperactivity disorder (ADHD). Cardiovascular adverse effects like vasospasm or myocardial infarction are described as very rare adverse effects. We present the case of a 21-year-old man diagnosed with ADHD who recently started therapy with Ritalin® Adult 20 mg for at least 3 days. Afterwards he ...

OBJECTIVE Evaluate nonmedical use (NMU) of ADHD prescription stimulants (Ritalin(®), Adderall(®), Adderall(®) XR, Concerta(®), and Vyvanse(®)) in a U.S. adult general population sample. METHOD In all, 10,000 adults (aged 18-49) from an online, opt-in panel, proximity matched to U.S. Census demographics, were surveyed to assess NMU prevalence, routes of administration (ROA), reasons for NMU, a...

objective: attention deficit hyperactivity disorder (adhd) is a fixed pattern of disregard and hyperactivity that is much more severe than what is normal in children of the same age. multiple drugs are used for the treatment of children with adhd however, their side effects and efficacy are not clearly known. this study was designed to evaluate and compare the therapeutic effects of two drugs, ...

Matched combinations of Brønsted or Lewis acids with suitable pro-electrophiles and secondary amine organocatalysts enable the novel enantioselective syntheses of carbamoyl dihydroquinoline and tetrahydropyridine derivatives with concomitant formation of two stereocenters. A short formal asymmetric synthesis of (2R,2'R)-threo-methylphenidate (Ritalin) is also described.

WASHINGTON—Advanced imaging research has answered a 40-year-old question about methylphenidate (Ritalin), which is taken daily by 4 million to 6 million children in the United States: how does it work? The answer may unsettle many parents, because the drug acts much like cocaine, albeit cocaine dripped through molasses ( J Neurosci. 2001;21:RC121). Taken orally in pill form, methylphenidate rar...
