PROTECTING YOUR PRACTICE AND PATIENTS FROM PRESCRIPTION DRUG ABUSE RON GASBARRO, PHARM.D. PROTECTING YOUR PRACTICE AND PATIENTS FROM PRESCRIPTION DRUG ABUSE ACTIVITY DESCRIPTION ACCREDITATION Prescription drug abuse is one of the most serious and critical public health concerns in the country. The FDA, DEA, state and local agencies continue to focus assets on reducing prescription drug abuse. As a pharmacist, it often seems that these agencies are targeting pharmacists and pharmacies to ensure controlled substance prescriptions are for legitimate purposes. Since pharmacists are frontline health care providers and the provider that actually fills the prescription, it is imperative that they receive the education and training to proactively work with patients and prescribers to identify, manage, and prevent prescription drug abuse. This knowledge based program will focus on the enormous challenges that prescription drug abuse has in the United States and the pivotal role that pharmacists can play working with both prescribers and patients to identify, reduce and prevent abuse and misuse.

According to the IMS Institute for Healthcare Informatics, a pharmaceutical market intelligence firm, the number one prescribed medication in the United States for 2009, 2010, 2011, 2012, and 2013 was hydrocodone/acetaminophen [Table 1] [IMS, 2014]. That’s over 129 million prescriptions annually. If each prescription were written for 60 tablets, then Americans would be swallowing 7.8 billion tablets a year. To put it in perspective, if you were the only pharmacist in the country and you had to count out 7.8 billion tablets of hydrocodone, day and night, you would be counting for 740 years – goodbye retirement! This exercise will discuss the pathophysiology of opioid addiction, strategies to identify and report individuals who may be abusing opioids, and methods by which healthcare professionals, as well as government agencies can help minimize opioid abuse in every community. Drug dealers are no longer the primary source of illicit drugs. Your pharmacy is. As pharmacists, you know darn well that many patients are abusing drugs, diverting them into the community, and when they graduate to heroin, they are selling them to “narcotic newbies,” often teens, which perpetuates the cycle of addiction. This constitutes a public health crisis. According to the Centers for Disease Control and Prevention (CDC), overdose deaths from prescription painkillers have skyrocketed in the past 10 years [CDC, 2012]. Approximately 16,500 people die each year from overdoses involving these drugs—more than those who die from heroin and cocaine combined – more than the number of deaths from both suicide and motor vehicle crashes [Manchikanti, 2012]. This would be the equivalent to losing an airplane carrying 90 passengers and crew every day for 6 months – clearly unacceptable from a public health and safety standpoint. Overdoses involving prescription painkillers—a drug class that includes hydrocodone as well as methadone, oxycodone, and oxymorphone—are almost becoming commonplace and these medications drugs are widely misused and abused. In 2010, one in 20 people in the United States, ages 12 and older, used prescription painkillers non-medically, without a prescription or just for the "high" they get. A recent CDC analysis discusses this growing epidemic and suggests measures for prevention [CDC, 2012]. 3 Consider that [CDC, 2012a]: Prescription painkiller overdoses in the United States have quadrupled since 1999. Nearly half a million emergency department visits in 2009 were due to people misusing or abusing prescription painkillers. Nonmedical use of prescription painkillers costs health insurers up to $72.5 billion annually in direct health care costs. Figure 1 shows rates of opioid pain reliever (OPR) overdose death, OPR treatment admissions, and kilograms of OPR sold in the United States during 1999-2010. Figure 2 shows rates of OPR overdose death, OPR treatment admissions, and kilograms of OPR sold in the United States during 1999-2010. During 1999-2008, overdose death rates, sales, and substance abuse treatment admissions related to OPR all increased substantially. Groups at greatest risk Certain groups are more likely to abuse or overdose on prescription painkillers: [CDC, 201a2] Many more men than women die of overdoses from prescription painkillers. Middle-aged adults have the highest prescription painkiller overdose rates. People in rural areas are about two-fold as likely to overdose on opioids as urbanites. Whites and American Indian or Alaska Natives are more likely to overdose on opioids. About 1 in 10 American Indian or Alaska Natives age 12 or older used opioids for nonmedical reasons in the past year, compared to 1 in 20 whites and 1 in 30 blacks [Table 3]. Doctors and drug dealers alike A noteworthy relationship exists between sales of opioid pain relievers and deaths. The majority of deaths (60%) occur in patients when they are issued prescriptions based on prescribing guidelines by medical boards, with 20% of deaths in low-dose opioid therapy of a morphine 100 mg equivalent dose or less per day and 40% in those receiving morphine of over 100 mg per day [Manchikanti, 2012]. In comparison, the remaining 40% of deaths occur in individuals abusing the drugs obtained through multiple prescriptions, doctor shopping, and drug 4 diversion. The obstacles that must be conquered are inappropriate prescribing patterns by physicians, which are largely based on a lack of knowledge, perceived safety, and an inaccurate belief that pain must be treated with as much drug as possible, rather than starting low, and increasing the doses as needed. The highs and lows of addiction Referring to his narcotics addiction, stand-up comic, social critic and satirist Lenny Bruce once said, "I'll die young, but it's like kissing God." In 1966 at age 40, he did die young via a morphine overdose. His life had been plagued by marital problems, legal woes, and a marginally successful career. In Bruce’s case which is mirrored in countless other cases, initiation of opioid abuse was related to familial and environmental influences such as peer pressure, disrupted family dynamics, and history of availability of opioids in the family [Neaigus, 2001]. Comorbid psychiatric disorders such as attention-deficit/hyperactivity disorder (ADHD), bipolar disorder, major depressive disorder (MDD), anxiety disorders, personality disorders, posttraumatic stress disorder (PTSD), and psychosis heighten the risk of substance abuse, including the abuse of opioids [Milby, 1996; Krausz, 1998; Callaly, 2001]. Chronic non-cancer pain syndromes that are treated with long-term opioid therapy have also been linked to an increase in opioid abuse in the US [Chapman, 2010; Nobel, 2010]. For drug dependence, considerable evidence suggests that genetic factors influence the risk of these disorders, with heritability estimates of 50% to 60%; it is very possible that multiple genes are involved [Dick, 2008]. Recent studies have indicated shared genetic influences that contribute to the risk for substance dependence as well as comorbid psychiatric disorders [Kendler, 2003]. Association with specific genes, such as the mu opioid receptor gene, has been suggested; however, evidence linking it to opioid use has not been fully elucidated [Gelernter, 2006]. More recently, prescription opioid abuse has been associated with a distinct set of demographics: younger age (20 to 29 years), white ethnicity, and better socioeconomic status with fewer comorbid mental illnesses [Mendelson, 2008]. 5 You’ve got opioids on the brain. Your body makes its own opioids when threatened by a noxious stimulus, which is an actually or potentially tissue damaging event. A noxious stimulus can be thermal (hot water), chemical (acid), or mechanical (a good hard pinch) [Loeser, 2008]. Opioid receptors in the brain are activated by a family of endogenous peptides such as the endorphins (endogenous morphine), which are released by neurons. Opioid receptors can also be activated exogenously by alkaloid opiates, such as morphine, which still remains the most valuable painkiller in contemporary medicine. By acting at opioid receptors, opiates such as morphine or heroin are extremely potent painkillers, but are also highly addictive molecules. A critical role in mediating opioid effects is the dopaminergic mesolimbic system (DMS), which originates in the ventral tegmental nucleus (VTN) with a projection to the nucleus accumbens [Spanagel, 1992]. The opioid receptor system includes mu, kappa, sigma, delta, and epsilon receptor subtypes and they tend to balance one another in the brain. Opioid-induced activation of mu and sigma receptors increases the activity of the DMS, thereby releasing dopamine into the nucleus accumbens to produce feelings of euphoria and well-being. Stimulation of the kappa receptors decreases activity of the DMS, which results in dysphoria, that is, the feelings of euphoria “wear off.” Opioid tolerance occurs when there is a decreased response by the opioid receptors in the brain to previous doses of an opioid [Spanagel, 1992]. A higher dose of opioid is then needed to stimulate the DMS and achieve the same release of dopamine in the nucleus accumbens. Enzymatic inhibition occurs at the mu receptors in the locus ceruleus (an area at the base of the brain producing norepinephrine, maintaining normal wakefulness, alertness, and hemodynamic stability) in the presence of opioids initially, and norepinephrine production decreases [Kosten, 2002; Koob, 2001]. However, chronic use of opioids leads to increased enzymatic activity at the mu receptors, thereby resulting in normal or higher levels of norepinephrine. Following opioid deprivation, such as during withdrawal, there is loss of inhibitory effect on enzyme activity 6 leading to an excess release of norepinephrine from these neurons, resulting in symptoms such as muscle cramps, diarrhea, anxiety, and tremors. Dependence on opioids is maintained by the rewarding effect of opioids mediated through the DMS, and avoidance of the aversive opioid withdrawal symptoms mediated through the norepinephrine pathways [Kosten, 2002]. Dysfunction in other brain areas such as the prefrontal cortex, and neurochemicals such as cortisol, also appear to play a role. The differences between opioid abuse, dependence, and addiction Opioids are very important medications in that they can relieve intractable pain. Not every person who takes opioids is a criminal or an addict. Addiction is drug seeking behavior. If you have cancer and your physician prescribes an opioid for you, then you are controlling your pain and improving your quality of life. True, people inadvertently get hooked on opioids in the course of their treatment. However, as a pharmacist, you can educate your patients as to the risks and benefits of using opioids. Is the person who takes an opioid necessarily an addict? To some extent a continuum exists between opioid abuse, opioid dependence, and addiction. Individuals who use narcotics to the degree that they begin to interfere with the person's ability to do routine activities or fulfill regular responsibilities at home, at school, or at work would be considered to be abusing opioids [Zwanger, 2014]. Other signs that individuals are abusing opioids include maladaptive behaviors that negatively impact relationships, worsen interpersonal problems, or involve frequent legal problems related to opioid use. Side effects of oxycodone are illustrated in Figure 3. Individuals who have opioid dependence often will manifest some of the following symptoms: Ingestion of increasingly larger amounts of opioids or for longer periods of time than intended 7 Desire or compulsion to take the drug with significant amount of time spent obtaining opioids Withdrawal symptoms if the drug is stopped or the amount taken is reduced The need for increased amounts of drug to achieve the original effects (tolerance) Social, recreational, occupational, or pleasurable activities are neglected Persistent use of narcotics even when evidence that they are harmful to their body, mood, thinking, or actions. Addiction is elevated narcotic abuse that becomes a craving, with compulsive need to use opioids and often displays self-destructive behavior. Prescription pain killers are the new gateway drugs. As one former addict stated, "I'd rather sell my prescriptions for better things, stronger things, to get as high as I could." A concern exists among treatment providers, policymakers, and others that nonmedical prescription pain reliever use can progress to heroin use [Muhuri, 2013]. Anecdotal reports and small-scale studies have suggested that some individuals who had been abusing OxyContin® switched to heroin after the reformulation in late 2010 that made OxyContin® more difficult to crush. Street price data from the Rocky Mountain Poison Control Center Drug Diversion Monitoring program indicate that the demand for the new formulation was much lower than that for the old formulation, which was more powerful, showed that the street price of the new formulation was 20% to 30% lower than that of the original formulation, indicating a lesser demand for the new formulation [Muhuri, 2013]. However, the reformulation may have led potential abusers of OxyContin® to switch to heroin, which is cheaper than pills. How is heroin linked to opioid abuse? Damaging health consequences resulting from the abuse of prescription opioid medications have radically increased in recent years. For example, unintentional poisoning deaths from prescription opioids quadrupled from 1999 to 2010 and now outnumber those from heroin and cocaine combined [Chen, 2013]. People often assume prescription analgesics are safer than illegal drugs because they are medically prescribed; however, when these drugs are taken for reasons 8 or in ways or amounts not intended by a doctor, or taken by someone other than the person for whom they are prescribed, they can result in severe adverse health effects including addiction, overdose, and death, especially when combined with other drugs or alcohol. Research now suggests that abuse of these medications may actually be a gateway to heroin use. Three recent studies have shown that almost 50% of young people who inject heroin reported abusing prescription opioids before starting to use heroin [National Institute on Drug Abuse, 2014]. Some individuals reported switching to heroin because it is cheaper and easier to obtain than prescription opioids. How much is that oxy in the window? The street value of narcotics depends on where you live, but in most cases, the street value far exceeds the amount actually paid for the prescription. Street prices of diverted prescription opioids can provide an indicator of drug availability, demand, and abuse potential, but these data can be difficult to collect. Crowdsourcing is the process of obtaining needed services, ideas, or content by soliciting contributions from a large group of people, and especially from an online community, rather than from traditional employees or suppliers, or in this case, people who abuse drugs. It is a rapid and cost-effective way to gather information about sales transactions. The crowdsourcing research website, StreetRx.com, displays user-submitted information on the latest street prices for prescription drugs. StreetRx relies on user-submitted information and therefore data should be interpreted accordingly. All submissions are anonymous. StreetRx is not affiliated with any government or law enforcement agency. See Table 4. According to one study, StreetRx revealed the mean prices per milligram were $3.29 for hydromorphone, $2.13 for buprenorphine, $1.57 for oxymorphone, $0.97 for oxycodone, $0.96 for methadone, $0.81 for hydrocodone, $0.52 for morphine, and $0.05 for tramadol [Dasgupta, 2013]. Street prices generally followed clinical equianalgesic potency. Therefore, if your patient is on medical assistance and has gotten 120 tablets of oxycodone 10mg for a $2 co-pay, that prescription has a street value of $1,164 – a 58,500% mark-up and a $1,162 profit. 9 Clinical scenarios Dishonesty, violence and risk-taking are survival skills in active addiction. Certainly, most patients who come into your pharmacy with regular prescriptions for opioids have a legitimate medical reason for taking them. One could even argue that the person who you suspect is addicted to opioids continues to receive the medication if that person plays by the rules, goes to the same doctor, and does not ask for early fillings. Nevertheless, be cautious when questioning the validity of a narcotic prescription. You can go into the back and phone the prescriber. When informing the patient that the prescription cannot be filled, keep your distance from the person. For example, do not go from the counter into the main part of the pharmacy as active addicts can be desperate and therefore prone to violence. Call the police at the first obscenity or threat. The following are scenarios in which the pharmacist is put on the spot when a person comes in with a narcotic prescription. Scenario 1 – No identification A person comes into your pharmacy that you have never seen before. He presents you with a prescription for oxycodone/acetaminophen and his insurance card. You take his birth date, address, phone number and ask if he has any notable allergies. You ask for a picture ID and he replies that his insurance card is his ID. You explain that there is no picture on the card and that you would need a picture ID. He hands you his VISA card which he says confirms his identity. What do you do next? It depends in which state you are practicing pharmacy. According to the CDC, as of August 31, 2010, 22 states now have laws requiring an ID prior to dispensing [Figure 4] [CDC, 2012b]. Typically, asking for ID is at the discretion of the pharmacist or in certain circumstances, e.g., the person has similar prescriptions from multiple practitioners, the patient wants to pay in cash, the prescription was written in another state, or the prescription was not covered at least in part by a health plan. In some states, if a person bringing in the prescription does not have ID, pharmacist may still dispense if the pharmacist can confirm ID and/or the validity of the 10 prescription by other means, or the pharmacist determines that a detriment to the patient will result if the prescription is not filled. Scenario 2 – Interstate dispensing You are working in a pharmacy in Maryland and a patient presents a prescription for hydrocodone bitartrate/acetaminophen 5mg/500mg #30. It contains all the necessary elements for a prescription, but you notice that the doctor’s address is Florida and the patient’s address is Delaware. What should you consider when determining whether to dispense the prescription? Can you legally dispense a prescription from an out of state prescriber? Yes, a pharmacist may dispense a controlled substance pursuant to a prescription of an out-of-state practitioner of medicine, osteopathy, podiatry, dentistry or veterinary medicine authorized to issue such prescription if the prescription complies with the requirements of that state. Next, is there a valid practitioner-patient relationship? Maybe, but you may need to obtain more information from the patient or the prescriber to determine this. Ask the patient “Was this prescription given to you in the doctor’s office in Florida? If not, how did you obtain this prescription? Have you ever been seen by this prescriber or one of his colleagues?” The patient stated that the prescription was not received in the doctor’s office, but was mailed to him, after completing an online questionnaire. Thus, the prescription lacks a bona fide physician-patient relationship. Decline to fill the prescription. It is not acceptable for a patient to complete an online questionnaire or to simply provide medical records to the prescriber. The prescriber must have a record on file of the patient and must have performed an in-office physical evaluation at some point. Scenario 3 – The patient asks a favor A patient presents a prescription for oxycodone/acetaminophen 5mg/325mg, 1 tab q6h prn pain, #150. Her insurance will only cover 120 tablets. She states that she would like the 11 remaining 30 tablets and that she will pay cash for them. Is this acceptable? Probably not. The pharmacy’s official dispensing records must show only one transaction which accurately indicates the total number of tablets dispensed pursuant to this prescription. The dispensing record may not appear as two transactions since a Schedule II may not be refilled and this does not comply with the provisions for allowable partial dispensing of Schedule II drugs. Scenario 4 – The Canadian quandary You receive a call from a pharmacist in Canada who is requesting a prescription transfer. Additionally, you learn that the patient has been communicating with the Canadian pharmacist and prompted him to call you for the transfer. Should you transfer the prescription to accommodate the patient’s request? No. It is illegal for a pharmacy located in Canada to ship prescription drugs into the United States, therefore, this prescription cannot be legally filled or refilled in this instance. The ABCs of starting over – Withdrawal and relapses According to the National Institute on Drug Abuse, the severity of opioid withdrawal may be placed into 1 of 4 categories [Trachtenberg, 2014]. Grade 0 opiate withdrawal is characterized by drug craving, anxiety and intense drug-seeking behavior; grade 1 by yawning, sweating, lacrimation and rhinorrhea; grade 2 by mydriasis, gooseflesh, muscle twitching and anorexia; and grade 3 by insomnia, increased pulse, respiratory rate and blood pressure, abdominal cramps, vomiting, diarrhea and weakness. If an opioid agonist is to be used, the preferred drug in the treatment of opiate withdrawal is methadone [Somogyi, 2014]. Methadone is mainly used in the treatment of opioid dependence. It has a cross-tolerance with other opioids including heroin and morphine, and offers very similar effects but a longer duration of effect. Oral doses of methadone can stabilize patients by mitigating opioid withdrawal syndrome or making it more tolerable. Higher doses of methadone can block the euphoric effects of heroin, morphine, and similar drugs. As a result, 12 properly dosed methadone patients can reduce or stop altogether their use of these substances. Some symptomatic relief may be obtained with clonidine as well [Trachtenberg, 2014]. Clonidine is a centrally acting alpha-adrenergic agonist and usually used an antihypertensive medication. As an agent for opiate withdrawal, clonidine suppresses restlessness, lacrimation, rhinorrhea and sweating. Because of the ease with which clonidine tablets can be sold on the street by patients to others seeking a self-treatment of opiate withdrawal, many physicians prefer to use transdermal clonidine for this indication. Because clonidine does not treat some of the symptoms associated with severe withdrawal, other non-controlled medications may be indicated when attempting to manage opiate withdrawal without the benefit of methadone. These include promethazine or hydroxyzine for nausea and vomiting, loperamide for diarrhea, and methocarbamol for muscle cramps and joint pain. Buprenorphine/naloxone (Bup/nx) is a partial μ-opioid agonist combined with the opioid antagonist naloxone in a 4:1 ratio [Mauger, 2014]. Its abuse potential is lower, and carries less stigma, allowing for more flexibility than methadone. Bup/nx is indicated for both inpatient and ambulatory medically assisted withdrawal (acute detoxification) and long-term substitution treatment (maintenance) of patients who have a mild-to-moderate physical dependence. A stepwise long-term substitution treatment with regular monitoring and follow-up assessment is usually preferred, as it has better outcomes in reducing illicit opioid use, minimizing concomitant risks such as human immunodeficiency virus and hepatitis C transmission, retaining patients in treatment and improving global functioning. A formulation of only buprenorphine is also available. It is given during the first few days of treatment, while Bup/nx is used during the maintenance phase of treatment. 13 The potential for relapse in alcohol and drug addiction appears to persist indefinitely [Trachtenberg, 2014]. The addicted person and the physician must be aware of this enduring risk. The acute craving may disappear after several weeks or months, but the relapse trigger may occur spontaneously at any time. Triggers may be purely internal or may be environmental, as in turning a corner and seeing a place or a person associated with addictive behavior in the past. Taking great pains to address the problem The intent of this information is not to discourage or prohibit the use of controlled substances where medically indicated. Having stated that, people at every level of society can take steps to help prevent overdoses involving prescription painkillers, while making sure patients have access to safe, effective treatment. Currently, the Federal government is a) tracking overdose trends to better understand the epidemic, b) working with stakeholder organizations to educate health care providers and the public about prescription drug abuse and overdose, and c) evaluating and promoting programs and policies shown to prevent prescription drug overdose, while making sure patients have access to pain treatment [CDC, 2014]. What can other groups do? States can: [CDC, 2014] Start or improve prescription drug monitoring programs (PDMPs), which are electronic databases that track all prescriptions for narcotics in the state. Use PDMP, Medicaid, and workers' compensation data to identify improper prescribing of controlled substances. Set up programs for Medicaid, workers' compensation programs, and state-run health plans that identify and address improper patient use of opiates. Pass, enforce and evaluate pill mill, doctor shopping and other laws to reduce prescription painkiller abuse. Encourage professional licensing boards to take action against inappropriate prescribing. Increase access to substance abuse treatment. 14 Citizens can: [CDC, 2014] Use prescription opioids only as directed by a health care provider. Make sure the patient for whom the drug is prescribed is the only one to use that drug; not selling or sharing them with others helps prevent misuse and abuse. Store all prescriptions in a secure place and dispose of them properly. Get help for substance abuse problems if needed (1-800-662-HELP). Health insurers can: [CDC, 2014] Set up prescription claims review programs to identify and address improper prescribing and use of narcotics. Increase coverage for other treatments to reduce pain, such as physical therapy, and for substance abuse treatment. Health care providers can: [CDC, 2014] Follow guidelines for responsible narcotic prescribing Screen and monitor for substance abuse and psychiatric problems. Prescribe painkillers only when other treatments have not been effective for pain. Write for only the quantity of pills needed, based on the expected length of pain. Use patient-provider agreements combined with urine drug tests for people using prescription controlled substances long term. Talk with patients about safely using, storing and disposing of prescription opioids. Use PDMPs to identify patients who are improperly using schedules 2 and 3 analgesics. Pharmacists can! As pharmacists, we have a personal responsibility to protect our practice from becoming an easy target for drug diversion. We need to know of the potential situations where drug diversion can occur, and establish safeguards to prevent drug diversion. In addition, the dispensing pharmacist must maintain a constant vigilance against forged or altered prescriptions. According to the Drug Enforcement Agency (DEA) which is under the aegis of the 15 U. S. Department of Justice, the 1970 Controlled Substance Act (CSA) holds the pharmacist responsible when he or she knowingly dispenses a prescription that was not issued in the usual course of professional treatment [USDOJ, 2014]. Look at any of the state’s board of pharmacy newsletters and you will see they are replete with reprimands, including fines and suspensions, against pharmacists for not following such laws. A controlled substance means just that Everyone has been hit up for early refills and often we must be the objects of their wrath when they do not get what they want. Dispensing procedures without control and professional caution are an invitation to the drug abuser. As the pharmacist, you control the drug’s trip out of the pharmacy. Proper management of controlled substances can be accomplished by following common sense, sound professional practice, and appropriate dispensing procedures. In addition, pharmacy technicians also should have knowledge of these mechanisms, as it will help prevent and protect the pharmacy from becoming a source of diversion [USDOJ, 2014]. Most drug abusers hunt for areas where communication and cooperation between health care professionals are minimal [USDOJ, 2014]. This makes the work of drug abusers less complicated. Therefore, a pharmacist should encourage other local pharmacists and physicians to develop a working relationship which will promote teamwork and solidarity. Additionally, we should become familiar with those controlled substances that are popular for abuse and resale on the streets in our areas and should discuss those findings with other pharmacists and practitioners in the community. 16 Table 1 – Top medicines by prescription count [IMS, 2014] Dispensed prescriptions* 2009 2010 2011 2012 2013 Total US market 3,953 3,995 4,022 4,139 4,208 1.
