Allowances have been made for your work schedules: Noon – 6 PM. You must be present and participate in all 18 hours of the training to receive certification. There can be no exceptions. Please stay focused. Be on task because we have a lot of material to cover in 3 days. Listening is a key to this training. Listen to new ideas. Listen to what’s coming up inside you in relation to what’s being presented. Try to put your thoughts and feelings into words instead of “shutting down.” Acknowledge and respect differences. You can “agree to disagree” on a contentious point and move on. Participate in role plays. Everyone has permission to pass. Offer feedback constructively not personally. Try to receive feedback as a gift. Learning Environment 9 Try to be okay with taking some learning risks. Stretch past your edge of what you know and what you are comfortable with. Confidentiality. Hold the container. Don’t be leaky. Turn off phones please. No cross talk. Allow one person to speak at a time. Equal time over time. Start and end on time, including breaks. Be alert to tendency to fudge this. Use “I” statements. Can everybody agree to this training contract? Is there anything you absolutely cannot live with? Now we are off. I. The Socio-Pharmacology of Opioid Use and Dependence 10 Heroin/Tidigesic/’Set’ Use= Social Heroin/opiate use, though physiological and experienced in the body, is socially mediated. What does this mean? 11 Initiation– relational, social Learning to use the drug. Administration The experience changes over time Managing the experience Contingencies What else? The production of getting “off” or getting “high”. 12 Brainstorm components of the production. List names of the social actors involved in the production. Identify social interactions. Identify cognitive and learning processes. Identify strategies of the heroin user or addict. What is Opioid dependence? 13 14 “Drug Use is The Root of Their Problems” 15 Substance use may be an expression of a problem rather than its cause. Rather than the cause of erratic or unhealthy behavior, substance use may be an adaptive mechanism or best solution to a range of problems including mental illness, abusive partner, homelessness, sexual abuse, poverty or other difficulties (Springer, 1991) “Bad Drug Using Women” 16 A survey of crack-using women in New York, for example, found that nearly 1/3 had a past history of abuse and prior hospitalization for mental illness (Chavkin, 1993). In another, women who were HIV+, were homeless in the last year, and had experienced combined physical and sexual abuse were also those most likely to report exchanging sex for drugs and money, using injection drugs in the past year, and having sex in crack houses (El Bassel et al, 2001). “An Addict Stays the Same or Gets Worse.” 17 Addiction is cyclic and variable in intensity. While some addicts may follow the pattern, made familiar by alcoholism, of chronic, progressive illness, others may have periods of intense drug use and dysfunction followed by long periods of being drug free or vice versa (Kane, 1999). Compare cocaine bingeing and heroin “It’s Their Choice; it’s Their Own Fault.” 18 Ongoing substance use is rarely a simple question of choice. Much as with people in abusive relationships or those with compulsive disorders, “choice” for substance users is shaped by perceptions of self-efficacy, mental health status, and social conditions. “They stopped growing. They are not themselves. They are addicted.” 19 How do we know they stop growing? Who defines when people are themselves? How do we define these terms? Societal or cultural norms? How does the “planet heroin” story lead us to the disappearance of the person into the drug? How are heroin users accounts of themselves ignored or marginalized when we make these assumptions based on the label addict? “They are manipulative. They lie.” 20 Once a person is labeled a heroin addict, what assumptions do we make about them? How are they treated by health providers? Imagine yourself at your last job interview. “Whose Fault is it Anyway?” 21 Addiction– like hypertension, asthma, or diabetes– is chronic, relapsing condition whose etiology frequently includes a combination of behavioral, genetic, and environmental factors. As with substance users, only a minority of diabetics or hypertensives successfully abstain from the behaviors contributive to these conditions, yet these patients are not stigmatized, blamed for their condition, or denied health services (McLellelan et al, 1995) 1. How Do Drugs Work? Drug Action: Interconnection between neurology, the science of the nervous system, and chemistry Drug Effects represents broader phenomena than drug and living tissue association. Drug Factors, which originate outside the laboratory, in real life practice that shapes effects. 22 Drug Action I 23 In passing through the brain, a given drug (the “key”) will be attracted to, and will bind to a specific site in the brain (the lock). The sites in the brain that control certain organs are rich in receptors into which specific drugs “fit” much like a key into a lock; these same sites may lack receptors for other drugs. Drug Action II 24 For instance, after heroin turns into morphine in the body, morphine “fits into” the receptors in the brain that control breathing and heartbeat rate, and hence, a sufficiently large dose of this drug can shut down these two functions and cause death by overdose. Opiates: Duration of action 25 Methadone Oxycontin Heroin Dilaudid Codeine Demerol Fentanyl 24 hours 12 hours 6-8 hours 4-6 hours 3-4 hours 2-4 hours 1-2 hours Heroin In The Brain 26 Short-term Effects Of Heroin Use 27 Soon after injection (or inhalation), heroin crosses the blood-brain barrier. In the brain, heroin is converted to morphine and binds rapidly to opioid receptors. Abusers typically report feeling a surge of pleasurable sensation, a "rush." Short-term Effects Of Heroin Use 28 The intensity of the rush is a function of how much drug is taken and how rapidly the drug enters the brain and binds to the natural opioid receptors. Heroin is particularly addictive because it enters the brain so rapidly. Short-term Effects Of Heroin Use With heroin, the rush is usually accompanied by The rush may also be accompanied by 29 A warm flushing of the skin, Dry mouth, and A heavy feeling in the extremities, Nausea, Vomiting, and Severe itching. Short-term Effects Of Heroin Use 30 After initial effects, drowsy for several hours. Mental function clouded by effect on CNS. Cardiac function slows. Breathing severely slowed, sometimes to the point of death. Overdose is a particular risk on the street, where the amount and purity of the drug cannot be accurately known. Short-term Effects Of Heroin Use 31 “Rush” Depressed Respiration Clouded Mental Functioning Nausea and Vomiting Suppression of pain Spontaneous abortion Heroin Intoxication 32 Pupil size (pinned pupils) Voice (slower, lower in tone) Conversations (talkative) Being high (feeling warm, euphoric, content) Scratching Droopy eyes Itchiness? Blood spots (needle marks bleed) Expansive mood Nodding out (sleep-like state) Drug Action and Drug Effects 33 It is crucial to make a distinction between the specific pharmacological action of a drug, which is the product of a biological and chemical process, and drug effects. Drug Effects 34 Drug effects is far more than the chemistry of a drug placed in the setting of living tissue. They represent the nonspecific factors that influence drug effects. Six more or less pharmacological dimensions: (1) identity and half-life in the body; (2) dose; (3) potency and purity; (4) drug mixing; (5) route of administration; (6) habituation. Five additional factors that originate outside the laboratory setting in real life practice 35 Set Setting Script Schedule (раскумарчтвся or morning shot) Structure Tolerance Need for increased amounts of the drug to achieve desired effect Markedly diminished effect with continued use of the same amount of the drug Withdrawal 36 Characteristic withdrawal syndrome The same (or closely related) drug is taken to relieve or avoid withdrawal symptoms The drug is taken in larger amounts or over a longer period than was intended There is a persistent desire or unsuccessful efforts to cut down or control drug use A great deal of time is spent in activities necessary to obtain the drug Important social, occupational or recreational activities are given up or reduced Drug use is continued despite knowledge of having a persistent or recurrent problem that is likely to have been caused or exacerbated by the drug use What is Substance Dependence 37 As the DSM IV explains, the term “addiction” is no longer widespread in the medical community, and has been widely replaced by the term “drug {or substance} dependence. They also note that the term “drug {or substance abuse} abuse” is: “a highly complex, value-laden and often excessively vague term that does not lend itself completely to any single definition.” Furthermore, because the term has different meanings for different groups of people– and their definition of the term reflects their different perspectives– there is often difficulty in drawing a line between use of substances and abuse of substances (Brands et al., 1998, 45). Dependence Syndrome 38 Dependence syndrome consists of the particular behavioral, cognitive and physiological effects that may arise through repeated substance use. Psychological characteristics include a strong desire to take the drug (craving), impaired control over its use, persistent use despite harmful consequences, and the prioritization of drug use over other activities and obligations. Physical dependence comprises increased tolerance and a physical withdrawal reaction that occurs when drug use is discontinued (WHO 1984) The DSM-IV* Specifies Criteria for Opioid Dependence: “A maladaptive pattern of substance use, leading to clinically significant impairment or distress, as manifested by three (or more) of the following, occurring any time in the same 12-month period: tolerance, as defined by either of the following: a) b) A need for markedly increased amounts of the substance to achieve intoxication or desired effect Markedly diminished effect with continued use of the same amount of the substance. *American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorder (DSM-IV) 39 The DSM-IV Specifies Criteria for Opioid Dependence: Withdrawal, as manifested by either of the following: a) b) 40 The characteristic withdrawal syndrome for the substance The same (or a closely related) substance is taken to relieve or avoid withdrawal symptoms The substance is often taken in larger amounts or over a longer period than was intended There is a persistent desire or unsuccessful efforts to cut down or control substance use The DSM-IV Specifies Criteria for Opioid Dependence: 41 A great deal of time is spent in activities necessary to obtain the substance, use the substance, or recover from its effects Important social, occupational, or recreational activities are given up or reduced because of substance use The substance use is continued despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by the substance Perspectives on Drug Dependence 42 The unfolding nature of heroin dependence Different types of dependencies and patterns of practices. Drug dependence is complex and variable but literature speaks in absolutes Fluid phenomenon: movable famine Drug users are thinking, strategizing Range of different therapies/services for multiple and incremental outcomes Tolerance and Habituation 43 When a person uses heroin regularly, they develop a tolerance– they have to use more heroin to get the same effects. The greater the amount and frequency of their use, the faster they become tolerant. Some people try to “chip” or use only occasionally, avoiding two days in a row. Others try to “manage their habits” by using a little less for a day or two to lower their tolerance, allowing them to decrease the amount needed to get high-- or well. Overdose 44 Overdose is a serious health risk for heroin users. Heroin slows down the heart rate and breathing; someone who overdoses may eventually stop breathing altogether. Mixing heroin with other drugs (valium, alcohol, cocaine) significantly increases risk of overdosing, especially alcohol. Active Drug users can be approached about overdosing: 45 Avoid mixing heroin with other drugs, especially “benzos” (Xanax, Clonopin, Ativan, Valium), other “downs” (Seconal, Elavil, Placidyl) or alcohol. Many drug users overdose after coming out of jail because their tolerance has fallen. Users should do a tester shot if it is from a new source or they have not used in a while. Overdose are very serious but do not have to be fatal: 46 Drug users should talk with using partners and make a plan for dealing with ODs. If they have thought it through, they are less likely to panic or freeze up in the event of an actual OD. Drug users should know about Naloxone, what paramedics use, and can call 1 866 STOP ODS for more information. Drug users can learn rescue (mouth to mouth) breathing, which is the most important thing they can do to help someone survive an overdose. Heroin Withdrawal (1 of 2) 47 Elevated Blood Pressure & Pulse Insomnia (can last for days or weeks) Restlessness Anxiety (confusion, exaggerated startle reflex) Irritability Body aches Lacrimation Sneezing Heroin Withdrawal (2 of 2) 48 Runny nose Piloerection (body hair stands up) Nausea and vomiting (can lead to dehydration) Sweating Diarrhea Deep muscle twitch Spontaneous erection or ejaculation (due to hypersensitivity) Pupil dilation (enlarged pupils) Long-term Effects Of Heroin Use 49 Dependence Infectious Diseases: HIV/AIDS, Hepatitis B & C Collapsed veins Bacterial Infections Abscesses Infection of heart lining and valves Arthritis and other rheumatologic problems Long-term Effects Of Heroin Use Physical dependence develops with higher doses of the drug. 50 The body adapts to the presence of the drug and withdrawal symptoms occur if use is reduced abruptly. Withdrawal may occur within a few hours after the last time the drug is taken. Long-term Effects Of Heroin Use Symptoms of withdrawal include: 51 Restlessness Muscle and bone pain Insomnia Diarrhea Vomiting Cold flashes with goose bumps ("cold turkey") Leg movements. Long-term Effects Of Heroin Use 52 Major withdrawal symptoms peak 24 - 48 hours after the last dose of heroin and subside after about a week. Some people have shown persistent withdrawal signs for many months. Heroin withdrawal is never fatal to otherwise healthy adults, but it can cause death to the fetus of a pregnant addict. Chronic Use: Medical Complications 53 Scarred and/or collapsed veins Bacterial infections of blood vessels and heart valves Abscesses (boils) and other soft-tissue infections Liver or kidney disease Lung complications (e.g., pneumonia, TB) may result from the poor health condition of the abuser as well as from heroin's depressing effects on respiration. Sources of Skin Infections 54 User’s skin and mouth (most common) Syringe Cooker Dissolving water Filter Drugs and contaminants Danger Signs Fever and chills Increased pulse Difficulty breathing Altered mental status/confusion Can progress to 55 Sepsis Necrotizing fascitis (gangrene, streptococcus) Wound botulism or tetanus Prevention of Infection 56 New needle for each injection or reduction in reuse Site rotation Alcohol wipes or soap and water for at least one minute Cook heroin until it bubbles Plan for missing the vein Chronic Use: Medical Complications 57 Clogging of blood vessels that lead to the lungs, liver, kidneys, or brain (due to the many additives in street heroin which may not readily dissolve) resulting in infection or even death of small patches of cells in vital organs. Immune reactions to these or other contaminants can cause arthritis or other rheumatologic problems. Chronic Use: Medical Complications 58 Sharing “works” or fluids can lead to some of the most severe consequences of heroin abuse-infections with hepatitis B and C, HIV, and a host of other blood-borne viruses, which drug abusers can then pass on to their sexual partners and children. Heroin Abuse & Pregnancy 59 Heroin abuse can cause serious complications during pregnancy, including miscarriage and premature delivery. Children born to addicted mothers are at greater risk of SIDS (Sudden Infant Death Syndrome), as well. Heroin Abuse & Pregnancy 60 Pregnant women should not be detoxified from opiates because of the increased risk of spontaneous abortion or premature delivery; rather, treatment with methadone is strongly advised. Infants born to mothers taking prescribed methadone may show signs of physical dependence but they can be treated easily and safely in the nursery. Research has demonstrated also that the effects of in utero exposure to methadone are relatively benign. Heroin Use & Blood-borne Diseases 61 At risk for contracting HIV, hepatitis C, and other infectious diseases through sharing and reusing syringes and injection paraphernalia that have been used by infected individuals. They may also become infected with HIV and, although less often, to hepatitis C through unprotected sexual contact with an infected person. Injection drug use has been a factor in an estimated one-third of all HIV and more than half of all hepatitis C cases in the Nation. Heroin Use & Blood-borne Diseases Users can change the behaviors that put them at risk for contracting HIV, through drug abuse treatment, prevention, and community-based outreach programs, including harm reduction. Users can reduce or eliminate the risk of exposure to HIV/AIDS and other infectious diseases by decreasing/eliminating: 62 drug use Injection drug use drug-related risk behaviors such as needle sharing unsafe sexual practices II. Introduction and background of oral substitution treatment 63 What is Oral Substitution Therapy (OST)? How does Methadone Work? Rationale for and Uses of OST What types of OST are Most Effective? Increasing Access to OST in Nepal: Identifying and Overcoming Barriers Developing a Continuum of MMT Program Delivery Vernacular Formulations of Substitution Therapies 64 Irregular supply, fluctuations in price and purity mean dangers for drug users and others Drug users are already creating their own forms of replacement therapy Although we call it ‘methadone maintenance,’ it is a form of drug treatment 65 66 67 68 69 70 The Basic Orientation 71 THE PATIENT: like all other patients THE CONDITION: like all other chronic medical conditions THE MEDICATION: like all others used in medicine CHINA VISIT APRIL 7-14, 2005 The Baron Edmond de Rothschild Chemical Dependency Institute 72 73 74 75 76 77 78 79 80 81 What is Methadone? Formulation: Oral solution, liquid concentrate, tablet/diskette, and powder Receptor Pharmacology: Full mu, opioid agonist Regulation: Proscriptive regulations fail to leave room for treatment flexibility and innovation (SAMSHA, U.S. Department of Health and Human Services: Treatment Improvement Protocol 43: 22) 82 How Does Methadone Work? 1 83 Opiate agonists bind to the mu opiate receptors on the surfaces of brain cells, which mediate the analgesic and other effects of opioids. Methadone produces a range of mu agonist effects similar to those of shortacting opioids. How Does Methadone Work? 2 84 Therapeutically appropriate doses of this agonist medication produce cross-tolerance for short acting opioids such as morphine and heroin, thereby suppressing withdrawal symptoms and opioid craving as a short-acting opioid is eliminated from the body. The dose needed to produce cross-tolerance depends on the individual patient’s level of tolerance for shortacting opioids. How Does Methadone Work? 3 85 When given intramuscularly or orally, methadone suppresses pain for 4 to 6 hours. Intramuscular is used only for patients who cannot take oral methadone, for example, patients in medicationassisted treatment for opioid dependence who are admitted to a hospital for emergency medical procedures. How Does Methadone Work? 4 86 Methadone is metabolized chiefly by the cytochrome P3A4 (CYP3A4) enzyme system (Oda and Kharasch 2001), which is significant when methadone is coadministered with other medication that also operate along this metabolic pathway. How Does Methadone Work? 5 87 After patient induction into methadone pharmacotherapy, a steady-state concentration (i.e., the level at which the amount of drug entering the body equals the amount being excreted) of methadone usually is achieved in 5 to 7.5 days (four to five half-lives of the drug). How Does Methadone Work? 6 88 Methadone’s pharmacological profile supports sustained activity at the mu opiate receptors, which allows substantial normalization of many physiological disturbances resulting from the repeated cycles of intoxication and withdrawal associated with dependence on shortacting opioids. How Does Methadone Work? 7 89 Therapeutically appropriate doses of methadone also attenuate or block the euphoric of heroin and other opioids. When opiate medication dosage must be adjusted to compensate for the effects of interacting drugs (e.g., Rifampin for TB), observe patients for signs or symptoms of opioid withdrawal or sedation to determine whether they are under medicated or overmedicated. How Does Methadone Work? 8 90 Methadone is up to 80% orally bioavailable, and its elimination half-life ranges from 24 to 36 hours. When methadone is administered daily in steady oral doses, its level in blood should maintain a 24-hour asymptomatic state, without episodes of overmedication or withdrawal (Payte and Zweben 1998). How Does Methadone Work? 9 91 Methadone’s body clearance rate varies considerably between individuals. The serum methadone level (SML) and elimination half-life are influenced by several factors including pregnancy and a patient’s absorption, metabolism and protein binding, changes in urinary pH, use of other medications, diet, physical conditions, age, and use of vitamin and herbal products (Payte and Zweben 1998). Early Research Findings Vincent P. Dole 1980, 1988 Patients do not experience euphoric, tranquilizing, or analgesic effects. Their affect and consciousness were normal. Therefore, they could socialize and work normally without the incapacitating effects of short-acting opioids such as morphine or heroin (SAMSHA, U.S. Department of Health and Human Services: Treatment Improvement Protocol 43: 17-18) 92 Early Research Findings Vincent P. Dole 1980, 1988 A therapeutic, appropriate dose of methadone reduced or blocked the euphoric and tranquilizing effects of all opioid drugs examined, regardless of whether a patient injected or smoked the drugs (e.g., morphine, heroin, opium, etc.) (SAMSHA, U.S. Department of Health and Human Services: Treatment Improvement Protocol 43: 17-18) 93 Early Research Findings Vincent P. Dole 1980, 1988 No change usually occurred in tolerance levels for methadone over time, unlike for morphine and other opioids; therefore, a dose could be held constant for extended periods (more than 20 years in some cases.) Methadone was effective when administered orally. Because it has a half-life of 24-36 hours, patients could take it once a day without a syringe. (SAMSHA, U.S. Department of Health and Human Services: Treatment Improvement Protocol 43: 17-18) 94 Early Research Findings Vincent P. Dole 1980, 1988 Methadone relieved the opioid craving or hunger that patients with addiction described as a major factor in relapse and continued illegal use Methadone, like most-opioid class drugs, caused what were considered minimal side effects, and research indicated that methadone was medically safe and nontoxic. (SAMSHA, U.S. Department of Health and Human Services: Treatment Improvement Protocol 43: 22) 95 Expansion of Methadone from Research to Public Health Program 96 Most patients were stabilized on methadone doses of 80 to 120 mg/day. Most patients who remained in treatment subsequently eliminated illicit-opioid use. In general, the team found that patients’ social functioning improved with time in treatment, as measured by elimination of illicit-opioid use and better outcomes in employment, school attendance, and domestic relations. Columbia University School of Public Health, Dr. Frances Rowe Gearing, 1974 Poly Substance Use and Abuse 97 However, 20 percent of more of these patients also had entered treatment with alcohol and poly substance abuse problems., despite intake screening that attempted to eliminate these patients from treatment. (Gearing and Schweitzer 1974) Methadone treatment was continued for these patients, along with attempts to treat their alcoholism and polysubstance abuse. MMTP Becomes A Major Public Health Initiative in the U.S. 98 Methadone maintenance became a major public health initiative to treat opioid dependence under the leadership of Dr. Jerome Jaffe, who headed the special Action Office for Drug Abuse Prevention in the Executive Office of the White House in the early 1970s. Dr. Jaffe’s office oversaw the creation of a nationwide , publicly funded system of treatment programs for opioid dependence The pharmacotherapy of opiate dependence Robert Newman, MD, Director, Baron Edmond de Rothschild Chemical Dependency Institute Beth Israel Medical Center, NYC Presented @ the 15th INTERNATIONAL CONFERENCE ON THE REDUCTION OF DRUG RELATED HARM, Melbourne, Australia, 20-24 April, 2004 99 The Baron Edmond de Rothschild Chemical Dependency Institute Methadone Maintenance (MMT).
