    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.

  • The Stimulants and Hallucinogens Under Consideration: a Brief Overview of Their Chemistry and Pharmacology
    Drug and Alcohol Dependence, 17 (1986) 107-118 107 Elsevier Scientific Publishers Ireland Ltd. THE STIMULANTS AND HALLUCINOGENS UNDER CONSIDERATION: A BRIEF OVERVIEW OF THEIR CHEMISTRY AND PHARMACOLOGY LOUIS S. HARRIS Dcparlmcnl of Pharmacology, Medical College of Virginia, Virginia Commonwealth Unwersity, Richmond, VA 23298 (U.S.A.) SUMMARY The substances under review are a heterogenous set of compounds from a pharmacological point of view, though many have a common phenylethyl- amine structure. Variations in structure lead to marked changes in potency and characteristic action. The introductory material presented here is meant to provide a set of chemical and pharmacological highlights of the 28 substances under con- sideration. The most commonly used names or INN names, Chemical Abstract (CA) names and numbers, and elemental formulae are provided in the accompanying figures. This provides both some basic information on the substances and a starting point for the more detailed information that follows in the individual papers by contributors to the symposium. Key words: Stimulants, their chemistry and pharmacology - Hallucinogens, their chemistry and pharmacology INTRODUCTION Cathine (Fig. 1) is one of the active principles of khat (Catha edulis). The structure has two asymmetric centers and exists as two geometric isomers, each of which has been resolved into its optical isomers. In the plant it exists as d-nor-pseudoephedrine. It is a typical sympathomimetic amine with a strong component of amphetamine-like activity. The racemic mixture is known generically in this country and others as phenylpropanolamine (dl- norephedrine). It is widely available as an over-the-counter (OTC) anti- appetite agent and nasal decongestant.

Woelfel, Ph.D., FASCP, R.Ph., Assistant Editor Health care professionals are frequently asked questions about false-positive drug testing results. Testing is a common practice in work settings, rehabilitation programs, the military, and legal and judicial venues. Home testing is popular with the availability of test kits to alleviate parental or job-seeker concerns. Federally regulated workplace drug testing and most private sector workplace programs specify urine testing as their initial standard test. Other expanded tests may be required in some settings.

  • Alcohol and Drug Abuse Subchapter 9
    Chapter 8 – Alcohol and Drug Abuse Subchapter 9 Regulated Drug Rule 1.0 Authority This rule is established under the authority of 18 V.S.A. §§ 4201 and 4202 which authorizes the Vermont Board of Health to designate regulated drugs for the protection of public health and safety. 2.0 Purpose This rule designates drugs and other chemical substances that are illegal or judged to be potentially fatal or harmful for human consumption unless prescribed and dispensed by a professional licensed to prescribe or dispense them and used in accordance with the prescription. The rule restricts the possession of certain drugs above a specified quantity. The rule also establishes benchmark unlawful dosages for certain drugs to provide a baseline for use by prosecutors to seek enhanced penalties for possession of higher quantities of the drug in accordance with multipliers found at 18 V.S.A. § 4234. 3.0 Definitions 3.1 “Analog” means one of a group of chemical components similar in structure but different with respect to elemental composition. It can differ in one or more atoms, functional groups or substructures, which are replaced with other atoms, groups or substructures. 3.2 “Benchmark Unlawful Dosage” means the quantity of a drug commonly consumed over a twenty-four-hour period for any therapeutic purpose, as established by the manufacturer of the drug. Benchmark Unlawful dosage is not a medical or pharmacologic concept with any implication for medical practice. Instead, it is a legal concept established only for the purpose of calculating penalties for improper sale, possession, or dispensing of drugs pursuant to 18 V.S.A.
