Methylphenidate Hydrochloride
Application for Inclusion to the 22nd Expert Committee on the Selection and Use of Essential Medicines: METHYLPHENIDATE HYDROCHLORIDE December 7, 2018 Submitted by: Patricia Moscibrodzki, M.P.H., and Craig L. Katz, M.D. The Icahn School of Medicine at Mount Sinai Graduate Program in Public Health New York NY, United States Contact: [email protected] TABLE OF CONTENTS Page 3 Summary Statement Page 4 Focal Point Person in WHO Page 5 Name of Organizations Consulted Page 6 International Nonproprietary Name Page 7 Formulations Proposed for Inclusion Page 8 International Availability Page 10 Listing Requested Page 11 Public Health Relevance Page 13 Treatment Details Page 19 Comparative Effectiveness Page 29 Comparative Safety Page 41 Comparative Cost and Cost-Effectiveness Page 45 Regulatory Status Page 48 Pharmacoepial Standards Page 49 Text for the WHO Model Formulary Page 52 References Page 61 Appendix – Letters of Support 2 1. Summary Statement of the Proposal for Inclusion of Methylphenidate Methylphenidate (MPH), a central nervous system (CNS) stimulant, of the phenethylamine class, is proposed for inclusion in the WHO Model List of Essential Medications (EML) & the Model List of Essential Medications for Children (EMLc) for treatment of Attention-Deficit/Hyperactivity Disorder (ADHD) under ICD-11, 6C9Z mental, behavioral or neurodevelopmental disorder, disruptive behavior or dissocial disorders. To date, the list of essential medications does not include stimulants, which play a critical role in the treatment of psychotic disorders. Methylphenidate is proposed for inclusion on the complimentary list for both children and adults. This application provides a systematic review of the use, efficacy, safety, availability, and cost-effectiveness of methylphenidate compared with other stimulant (first-line) and non-stimulant (second-line) medications. -

Elsevier Editorial System(tm) for Forensic Science International Manuscript Draft Manuscript Number: FSI-D-16-00226R1 Title: An overview of Emerging and New Psychoactive Substances in the United Kingdom Article Type: Review Article Keywords: New Psychoactive Substances Psychostimulants Lefetamine Hallucinogens LSD Derivatives Benzodiazepines Corresponding Author: Prof. Simon Gibbons, Corresponding Author's Institution: UCL School of Pharmacy First Author: Simon Gibbons Order of Authors: Simon Gibbons; Shruti Beharry Abstract: The purpose of this review is to identify emerging or new psychoactive substances (NPS) by undertaking an online survey of the UK NPS market and to gather any data from online drug fora and published literature. Drugs from four main classes of NPS were identified: psychostimulants, dissociative anaesthetics, hallucinogens (phenylalkylamine-based and lysergamide-based materials) and finally benzodiazepines. For inclusion in the review the 'user reviews' on drugs fora were selected based on whether or not the particular NPS of interest was used alone or in combination. NPS that were use alone were considered. Each of the classes contained drugs that are modelled on existing illegal materials and are now covered by the UK New Psychoactive Substances Bill in 2016.

Comparison of the Inhibitory and Excitatory Effects of ADHD Medications Methylphenidate and Atomoxetine on Motor Cortex
Neuropsychopharmacology (2006) 31, 442–449 & 2006 Nature Publishing Group All rights reserved 0893-133X/06 $30.00 www.neuropsychopharmacology.org Comparison of the Inhibitory and Excitatory Effects of ADHD Medications Methylphenidate and Atomoxetine on Motor Cortex ,1 2 3 1 1 4 Donald L Gilbert* , Keith R Ridel , Floyd R Sallee , Jie Zhang , Tara D Lipps and Eric M Wassermann 1 2 Division of Neurology, Cincinnati Children’s Hospital Medical Center, University of Cincinnati, Cincinnati, OH, USA; University of Cincinnati 3 4 School of Medicine, Cincinnati, OH, USA; Division of Psychiatry, University of Cincinnati, Cincinnati, OH, USA; Brain Stimulation Unit, National Institute of Neurological Disorders and Stroke, Bethesda, MD, USA Stimulant and norepinephrine (NE) reuptake inhibitor medications have different effects at the neuronal level, but both reduce symptoms of attention deficit hyperactivity disorder (ADHD). To understand their common physiologic effects and thereby gain insight into the neurobiology of ADHD treatment, we compared the effects of the stimulant methylphenidate (MPH) and NE uptake inhibitor atomoxetine (ATX) on inhibitory and excitatory processes in human cortex. Nine healthy, right-handed adults were given a single, oral dose of 30 mg MPH and 60 mg ATX at visits separated by 1 week in a randomized, double-blind crossover trial. We used paired and single transcranial magnetic stimulation (TMS) of motor cortex to measure conditioned and unconditioned motor-evoked potential amplitudes at inhibitory (3 ms) and facilitatory (10 ms) interstimulus intervals (ISI) before and after drug administration. Data were analyzed with repeated measures, mixed model regression. We also analyzed our findings and the published literature with meta-analysis software to estimate treatment effects of stimulants and NE reuptake inhibitors on these TMS measures. -
Methylphenidate Amplifies the Potency and Reinforcing Effects Of
ARTICLE Received 1 Aug 2013 | Accepted 7 Oct 2013 | Published 5 Nov 2013 DOI: 10.1038/ncomms3720 Methylphenidate amplifies the potency and reinforcing effects of amphetamines by increasing dopamine transporter expression Erin S. Calipari1, Mark J. Ferris1, Ali Salahpour2, Marc G. Caron3 & Sara R. Jones1 Methylphenidate (MPH) is commonly diverted for recreational use, but the neurobiological consequences of exposure to MPH at high, abused doses are not well defined. Here we show that MPH self-administration in rats increases dopamine transporter (DAT) levels and enhances the potency of MPH and amphetamine on dopamine responses and drug-seeking behaviours, without altering cocaine effects. Genetic overexpression of the DAT in mice mimics these effects, confirming that MPH self-administration-induced increases in DAT levels are sufficient to induce the changes. Further, this work outlines a basic mechanism by which increases in DAT levels, regardless of how they occur, are capable of increasing the rewarding and reinforcing effects of select psychostimulant drugs, and suggests that indivi- duals with elevated DAT levels, such as ADHD sufferers, may be more susceptible to the addictive effects of amphetamine-like drugs. 1 Department of Physiology and Pharmacology, Wake Forest University School of Medicine, Winston-Salem, North Carolina 27157, USA. 2 Department of Pharmacology and Toxicology, University of Toronto, Toronto, Ontario, Canada M5S1A8. 3 Department of Cell Biology, Medicine and Neurobiology, Duke University Medical Center, Durham, North Carolina 27710, USA.

Synthetic Cathinones ("Bath Salts")
Synthetic Cathinones ("Bath Salts") What are synthetic cathinones? Synthetic cathinones, more commonly known as "bath salts," are synthetic (human- made) drugs chemically related to cathinone, a stimulant found in the khat plant. Khat is a shrub grown in East Africa and southern Arabia, and people sometimes chew its leaves for their mild stimulant effects. Synthetic variants of cathinone can be much stronger than the natural product and, in some cases, very dangerous (Baumann, 2014). In Name Only Synthetic cathinone products Synthetic cathinones are marketed as cheap marketed as "bath salts" should substitutes for other stimulants such as not be confused with products methamphetamine and cocaine, and products such as Epsom salts that people sold as Molly (MDMA) often contain synthetic use during bathing. These cathinones instead (s ee "Synthetic Cathinones bathing products have no mind- and Molly" on page 3). altering ingredients. Synthetic cathinones usually take the form of a white or brown crystal-like powder and are sold in small plastic or foil packages labeled "not for human consumption." Also sometimes labeled as "plant food," "jewelry cleaner," or "phone screen cleaner," people can buy them online and in drug paraphernalia stores under a variety of brand names, which include: Flakka Bloom Cloud Nine Lunar Wave Vanilla Sky White Lightning Scarface Image courtesy of www.dea.gov/pr/multimedia- library/image-gallery/bath-salts/bath-salts04.jpg Synthetic Cathinones • January 2016 • Page 1 How do people use synthetic cathinones? People typically swallow, snort, smoke, or inject synthetic cathinones. How do synthetic cathinones affect the brain? Much is still unknown about how synthetic cathinones affect the human brain. -
