Opiate Fact Sheet 1 Learning Plan 8: Scoring Guide - Fact Sheet on Narcotic Analgesics (Opiates) Jennifer Dohl Physiological Complications and Psychopharmacology Jerry Van Kirk April 10, 2012 Opiate Fact Sheet 2 Definition of Opiates Opiates are central nervous system (CNS) depressants. Opioid narcotics activate opioid receptors in the brain and have high abuse potential. Their pharmacological features include pain-relieving effects (analgesic), cough suppressants (antitussive), and reduction of intestinal movement (Hanson, Venturelli and Fleckenstein, 2012). Types of Opiates Opioids are defined by their ability to bind to and influence opiate receptors on cell membranes. They are divided into 3 classes: Naturally occurring opioids: The classic natural opioids are opium and morphine. Semi-synthetic opioids: These include heroin, oxycodone, oxymorphone, and hydrocodone. Synthetic opioids: Synthetic opioids are made using total synthesis; they include buprenorphine, methadone, fentanyl, alfentanil, levorphanol, meperidine, codeine, and propoxyphene (Preda, 2012).

Potent analgesia Opiate Fact Sheet 4 Therapeutic Uses for Prescription Opiates Prescription opiates are used mostly to relieve various types of pain including; visceral (Internal organs) and somatic (skeletal muscles, bones, skin, and teeth). In high doses opiates can relieve pain associated with certain types of cancer. Opiates are also used as antitussives (relieve coughing), as an antidiarrheal and to treat narcotic dependence (Hanson, Venturelli and Fleckenstein, 2012). Physiological Effects from the Abuse of Opiates Any narcotic drugs that activate opioid receptors in the brain have abuse potential. Patients who are using opioid analgesics develop tolerance after 2-3 weeks of use and may develop physical dependence to them even if they are not abusing the drugs. Psychological dependence can develop with sustained use due to the euphoric and stress relieving effects of opiates. There are two major stages in the development of a psychological dependence and addiction to opiates, whether it’s a prescribed opioid analgesic or heroin. The first stage is the rewarding stage where the effects are positive feelings that are increased with continued use. In the next stage the user must keep using the drug to avoid unpleasant withdrawal symptoms. The side effects of using opioids are constipation, drowsiness, mental fogginess, respiratory depression (which can be fatal in cases of overdose), nausea, vomiting, dry mouth, pruritus, anuria, hypotension, pupil constriction (Hanson, Venturelli and Fleckenstein, 2012). Withdrawal Effects of Heroin and Opiate Abuse Withdrawal effects from opiate abuse include craving within 6 hours of last dose, followed by exaggerated pain responses, agitation, anxiety, stomach cramps, and vomiting, insomnia and an overall flu-like feeling. Withdrawal symptoms from heroin may start 4-6 hours after the last dose. The symptoms start with a runny nose, tears, mild stomach cramps, Opiate Fact Sheet 5 alternating chills and fever, and goose pimples. Within 2-4 days the previous symptoms continue along with aching bones and muscles, and powerful muscle spasms. After 4-5 days the withdrawal symptoms start to decrease for both opiates and heroin and the user will start to regain his/her appetite. Even after the initial withdrawal effects have stopped, the urge to use stays strong (Hanson, Venturelli and Fleckenstein, 2012). (Opioid Drug Abuse and Dependence, 2005) Health Risks of Opiate Abuse With the exception of overdose, usually through respiratory depression, and physical dependence, most effects from opiates are reversible. The biggest danger comes from the use of contaminated needles by intravenous users. The user is at risk for hepatitis B and C, bacterial endocarditis, and HIV. The ingredients added to street drugs may contribute to nervous system damage, including peripheral neuropathy, vision problems, myelopathy, and leukoencephalopathy (disease of the white matter of the brain). Opioid use may lead to decreased Opiate Fact Sheet 6 sex drive and problems in dealing with stress. Other hormonal changes include a decrease in the release of thyrotropin (hormone produced by the thyroid gland) and increases in prolactin (hormone that stimulates lactation) and possibly growth hormone (Lynch, McJunkin, Maloney, 2010). The potential effects of Heroin abuse include Hepatitis B and C, HIV, collapsed veins, bacterial infections, abscesses, infection of the heart lining and valves, arthritis and other rheumatologic problems (Focus Adolescent Services). Treatment Approaches to Opiate Abuse and Dependence There are a variety of treatment options for opiate narcotics and heroin addiction. Treatments include medications and behavioral therapies. Treatment usually starts with medically assisted detoxification so the patient withdraws from the drug safely. Clonidine (an oral antihypertensive also used as anti-emetic) and buprenorphine can be used to help minimize symptoms of withdrawal. To prevent relapse long term, treatment needs to include behavioral therapy as well. Medications to help prevent relapse consist of the following: Methadone-Taken orally, it has a gradual onset of action and prolonged effects, decreasing the craving for other opioid drugs and preventing withdrawal symptoms. When taken appropriately methadone is not intoxicating or sedating, and its effects do not interfere with normal day-to-day activities. Methadone maintenance treatment is usually given through specialized opiate treatment programs. Methadone can also be appropriate for addicted pregnant women when combined with prenatal care and a drug treatment program. Opiate Fact Sheet 7 Buprenorphine is also taken orally for the treatment of opiate and heroin addiction. Buprenorphine has less risk for overdose and withdrawal effects and produces a lower level of physical dependence than oral methadone. Buprenorphine can be prescribed in a doctor’s office which gives patients easier access and may be an incentive to some addicts to get help sooner. Naltrexone is appropriate for treating heroin addiction but has not been extensively used due to poor patient compliance. Naltrexone blocks opioids from binding to their receptors and stops the effects of the drug from being felt. For opioid addiction, naltrexone is usually prescribed in outpatient settings after detox in an inpatient facility. To prevent withdrawal symptoms, patients must be medically detoxified and opioid-free for several days before taking naltrexone. Naloxone is a shorter-acting opioid receptor blocker, used to treat cases of overdose (Infofacts Heroin, 2010). Another method of treatment is with ultra-rapid or anesthesia-assisted opioid detoxification which involves giving an opioid antagonist drug to neutralize the effects of heroin while the patient is under general anesthesia. This treatment is expensive, not covered by insurance, and lacks good evidence to prove its effectiveness. There are also concerns about potential health risks. The detoxification procedure is usually followed by longer term treatment with an antagonist drug such as naltrexone ("Study says rapid-detox," 2005). The best result of treatment for opiate or heroin addiction is for the individual to be able to live a well-adjusted, productive life free from drugs. However, realistically, treatment is deemed successful when the individual; Is no longer using heroin Opiate Fact Sheet 8 Ceases to associate with dealers or users Stays away from situations that put him/her at risk for temptation to use Maintains employment Avoids illegal activity Is capable of appreciating and participating in normal family and social relationships (Hanson, Venturelli, Fleckenstein, 2012).
