Fact Sheet on Methadone
Fact Sheet: Methadone Common Questions about Methadone • What is the typical dose of methadone and how is it taken? • How does someone know methadone is working? • How long does a person take methadone? • Who can prescribe methadone? • Can a person overdose on methadone? What is the typical dose of methadone and how is it taken? • Due to methadone’s slow and steady activation of opioid receptors, a person requires only one methadone dose per day. • Every person is different, and dosing should be individualized, based on a person’s experience of a reduction of withdrawal symptoms and cravings. • Most people start with an initial dose of 30-35 mg. It is then increased by 5mg every 3 days until a person experiences a relief from withdrawal symptoms.1 • Methadone is taken by mouth in a liquid form. • The recommended therapeutic (i.e., effective) dose of methadone is between 60 and 120 mg.1 How does someone know methadone is working? • The person will stop feeling withdrawal symptoms. • The person will also experience fewer cravings to use opioids. The intensity of their cravings will go down, but they may not completely go away.1 o Someone taking methadone may still have cravings to use other substances such as cocaine, benzodiazepines, alcohol, etc. The 3 Dimensions of Cravings: Frequency Duration Severity Number of separate times Once a craving starts, it Cravings range in a person starts to can range in how long it intensity, such as how experience a craving lasts at a high, distracting overwhelming, distracting, during the day. level.

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.

Methadone Hydrochloride Tablets, USP) 5 Mg, 10 Mg Rx Only
ROXANE LABORATORIES, INC. Columbus, OH 43216 DOLOPHINE® HYDROCHLORIDE CII (Methadone Hydrochloride Tablets, USP) 5 mg, 10 mg Rx Only Deaths, cardiac and respiratory, have been reported during initiation and conversion of pain patients to methadone treatment from treatment with other opioid agonists. It is critical to understand the pharmacokinetics of methadone when converting patients from other opioids (see DOSAGE AND ADMINISTRATION). Particular vigilance is necessary during treatment initiation, during conversion from one opioid to another, and during dose titration. Respiratory depression is the chief hazard associated with methadone hydrochloride administration. Methadone's peak respiratory depressant effects typically occur later, and persist longer than its peak analgesic effects, particularly in the early dosing period. These characteristics can contribute to cases of iatrogenic overdose, particularly during treatment initiation and dose titration. In addition, cases of QT interval prolongation and serious arrhythmia (torsades de pointes) have been observed during treatment with methadone. Most cases involve patients being treated for pain with large, multiple daily doses of methadone, although cases have been reported in patients receiving doses commonly used for maintenance treatment of opioid addiction. Methadone treatment for analgesic therapy in patients with acute or chronic pain should only be initiated if the potential analgesic or palliative care benefit of treatment with methadone is considered and outweighs the risks. Conditions For Distribution And Use Of Methadone Products For The Treatment Of Opioid Addiction Code of Federal Regulations, Title 42, Sec 8 Methadone products when used for the treatment of opioid addiction in detoxification or maintenance programs, shall be dispensed only by opioid treatment programs (and agencies, practitioners or institutions by formal agreement with the program sponsor) certified by the Substance Abuse and Mental Health Services Administration and approved by the designated state authority. -
Guidelines for Ketamine Use
St Joseph's Mercy Hospice Auckland NZ Guidelines for Ketamine Use Ketamine is a dissociative anaesthetic agent which has analgesic properties in sub- anaesthetic doses 1 Its principal site of action is in the dorsal horn of the spinal cord where it blocks the N-methyl D-aspartate (NMDA) receptor complex. Ketamine is used in palliative care settings primarily for neuropathic pain which is unresponsive or poorly responsive to first-line analgesics (which may include one or more of opioid drug, NSAID, tricyclic antidepressant, or anticonvusant) It has also been used for phantom limb and ischaemic pain and for intractable incident pain or prior to procedures such as dressing changes. Potential side effects Ketamine Routine use of ketamine is limited by its cost and potential side effects which may occur in up to 40% of patients; These may include: Psychotomimetic phenomena – “feeling strange” - dysphoria, vivid dreams, nightmares, hallucinations, altered body image. These effects may be minimised or treated by concurrent use of haloperidol or a benzodiazepine Delirium Hypertension, tachycardia Diplopia, nystagmus Erythema and pain at injection site Contraindications to ketamine use Ketamine has the potential to increase intra-cranial and intra-ocular pressures. It is contraindicated in patients with a history of hypertension, cerebrovascular disease or epilepsy and should be used with caution in patients with raised intra-cranial pressure and/or known cerebral metastases. Dosage regimens for Ketamine use 1. “Burst ketamine” 2 Ketamine is prescribed as a ‘burst’or ‘pulse’ course for a maximum of 5 days. The dose is titrated up, in a stepwise fashion, and once the lowest effective dose is achieved it is continued for 3 days at that dose then stopped. -
Methadone and the Anti-Medication Bias in Addiction Treatment
White, W. & Coon, B. (2003). Methadone and the anti-medication bias in addiction treatment. Counselor 4(5): 58-63. Methadone and the Anti-medication Bias in Addiction Treatment William L. White, MA and Brian F. Coon, MA, CADC An Introductory Note: This article is long overdue. Like many addiction counselors personally and professionally rooted in the therapeutic community and Minnesota model programs of the 1960s and 1970s, I exhibited a rabid animosity toward methadone and protected these beliefs in a shell of blissful ignorance. That began to change in the late 1970s when a new mentor, Dr. Ed Senay, gently suggested that the great passion I expressed on the subject of methadone seemed to be in inverse proportion to my knowledge about methadone. I hope this article will serve as a form of amends for that ignorance and arrogance. (WLW) There is a deeply entrenched anti-medication bias within the field of addiction treatment. This bias is historically rooted in the iatrogenic insults that have resulted from attempts to treat drug addiction with drugs. The most notorious of these professional practices includes: coaching alcoholics to substitute wine and beer for distilled spirits, treating alcoholism and morphine addiction with cocaine and cannabis, switching alcoholics from alcohol to morphine, failing repeatedly to find an alcoholism vaccine, employing aversive agents that linked alcohol or morphine to the experience of suffocation and treating alcoholism with drugs that later emerged as problems in their own right, e.g., barbiturates, amphetamines, tranquilizers, and LSD. A history of harm done in the name of good culturally and professionally imbedded a deep distrust of drugs in the treatment of alcohol and other drug addiction (White, 1998). -
(Methadone Hydrochloride Oral Concentrate USP) and Methadose
NDA 17-116/S-021 Page 3 Methadose™ Oral Concentrate (methadone hydrochloride oral concentrate USP) and Methadose™ Sugar-Free Oral Concentrate (methadone hydrochloride oral concentrate USP) dye-free, sugar-free, unflavored CII Rx only FOR ORAL USE ONLY Deaths have been reported during initiation of methadone treatment for opioid dependence. In some cases, drug interactions with other drugs, both licit and illicit, have been suspected. However, in other cases, deaths appear to have occurred due to the respiratory or cardiac effects of methadone and too-rapid titration without appreciation for the accumulation of methadone over time. It is critical to understand the pharmacokinetics of methadone and to exercise vigilance during treatment initiation and dose titration (see DOSAGE AND ADMINISTRATION). Patients must also be strongly cautioned against self- medicating with CNS depressants during initiation of methadone treatment. Respiratory depression is the chief hazard associated with methadone hydrochloride administration. Methadone's peak respiratory depressant effects typically occur later, and persist longer than its peak analgesic effects, particularly in the early dosing period. These characteristics can contribute to cases of iatrogenic overdose, particularly during treatment initiation and dose titration. Cases of QT interval prolongation and serious arrhythmia (torsades de pointes) have been observed during treatment with methadone.

Methamphetamine (Canadian Drug Summary)
www.ccsa.ca • www.ccdus.ca March 2020 Canadian Drug Summary Methamphetamine Key Points • The prevalence of methamphetamine use in the Canadian population is low (~0.2%). • Several jurisdictions report at least a three-fold increase in the use of methamphetamine over the past five years among individuals accessing treatment or harm reduction services. • Notable increases for rates of criminal violations involving methamphetamine have been observed in the last five years (2013–2018). Introduction Methamphetamine is a synthetic drug classified as a central nervous system (CNS) stimulant or psychostimulant. CNS stimulants cover a wide range of substances that act on the body by increasing the level of activity of the CNS and include caffeine, nicotine, amphetamine (e.g., Adderall®), methylphenidate (e.g., Ritalin®), MDMA (“ecstasy”), cocaine (including crack cocaine) and methamphetamine (including crystal meth).1,2 While both methamphetamine and amphetamine are psychostimulants and often grouped together, they are different drugs. A slight chemical modification of amphetamine produces methamphetamine, which has a different pharmacological profile that results in a larger release of certain neurochemicals in the brain and a stronger and more rapid physiological response. Some amphetamines are prescribed in Canada for attention-deficit hyperactivity disorder (ADHD) and narcolepsy (e.g., Adderall and Vyvanse®), but methamphetamine use is currently illegal. Methamphetamine is often made in illegal, clandestine laboratories with commonly available, inexpensive chemicals, such as ephedrine and pseudoephedrine, found in medications, among other sources. The use of these medications as precursor chemicals for methamphetamine led to stricter regulations introduced in Canada in 2006, limiting access to them by requiring they be kept behind the counter of pharmacies.3 Illegal production can be dangerous due to the toxicity of the chemicals used and the high risk of explosions. -

WHO Expert Committee on Drug Dependence
WHO Technical Report Series 1034 This report presents the recommendations of the forty-third Expert Committee on Drug Dependence (ECDD). The ECDD is responsible for the assessment of psychoactive substances for possible scheduling under the International Drug Control Conventions. The ECDD reviews the therapeutic usefulness, the liability for abuse and dependence, and the public health and social harm of each substance. The ECDD advises the Director-General of WHO to reschedule or to amend the scheduling status of a substance. The Director-General will, as appropriate, communicate the recommendations to the Secretary-General of the United Nations, who will in turn communicate the advice to the Commission on Narcotic Drugs. This report summarizes the findings of the forty-third meeting at which the Committee reviewed 11 psychoactive substances: – 5-Methoxy-N,N-diallyltryptamine (5-MeO-DALT) WHO Expert Committee – 3-Fluorophenmetrazine (3-FPM) – 3-Methoxyphencyclidine (3-MeO-PCP) on Drug Dependence – Diphenidine – 2-Methoxydiphenidine (2-MeO-DIPHENIDINE) Forty-third report – Isotonitazene – MDMB-4en-PINACA – CUMYL-PEGACLONE – Flubromazolam – Clonazolam – Diclazepam The report also contains the critical review documents that informed recommendations made by the ECDD regarding international control of those substances. The World Health Organization was established in 1948 as a specialized agency of the United Nations serving as the directing and coordinating authority for international health matters and public health. One of WHO’s constitutional functions is to provide objective, reliable information and advice in the field of human health, a responsibility that it fulfils in part through its extensive programme of publications. The Organization seeks through its publications to support national health strategies and address the most pressing public health concerns of populations around the world. -
