This article is based on the education ses-sion, Transforming the Future of Pain Man-agement, presented by Chris Herndon, Phar-mD, BCPS, CPE; and Phyllis Grauer, PharmD, CGP, CPE, at APhA2012, the American Phar-macists Association Annual Meeting & Ex-position.

This publication was prepared by Judy Crespi Lofton, MS, on behalf of the American Pharmacists Association.

Taking a look at pain in the United states Large national surveys have found that chronic pain is a common and serious prob-lem in the United States, and its incidence appears to be increasing (Figure 1).1 Pain can arise from a variety of common causes, including musculoskeletal pain, cancer pain, neuropathic pain, postsurgical pain, and visceral pain. According to the 2009 National Center for Health Statistics survey of noninstitutionalized civilian adults, the percentages of adults who reported experiencing various types of musculoskeletal pain within the previous 3 months was as follows2: severe headache or migraine, 16.1%; low back pain, 28.1%; neck pain, 15.1%; knee pain, 19.5%; shoulder pain, 9.0%; finger pain, 7.6%; and hip pain, 7.1%.

Patients with chronic pain report that it has a substantial impact on their ability to perform activities of daily living (Table 1).1

institute of Medicine report on pain and call to actionTo better assess the impact of pain in the United States, the Department of Health & Human Services directed the Institute of Medicine (IOM) to develop a report “to in-crease recognition of pain as public health problem in US” as required by the Afford-able Care Act of 2010.3 The resulting report, Relieving pain in America: A blueprint for transforming prevention, care, education and research, was released in June 2011.

The IOM report provides a comprehensive review of the growing public health problem of under- and untreated pain and the challenges of pain management. It does not provide clinical recommendations for managing pain. Instead, it describes the scope of the problem of pain and provides an overview of needs for care, education, and research. The IOM report echoes recommendations from the public health ini-tiative, Healthy People 2020, which included an objective to “increase the safe and effective treatment of pain.”4

The IOM report highlighted several facts that illustrate the substantial burden of chronic pain in the United States:

■ A total of 116 million adults experience chronic pain, which is greater than the number of adults with heart disease, diabetes, and all types of cancer combined.

Learning objectivesAt the conclusion of this knowledge-based activity, the pharmacist will be able to:

■ Discuss the findings and recommen-dations of the Institute of Medicine’s report, Relieving pain in America: A blueprint for transforming prevention, care, education and research.

■ Describe opportunities for pharma-cists to support improved pain man-agement for their patients.

■ Explain the components of the REMS (risk evaluation and mitigation strat-egy) for long-acting and extended-release opioids and its impact on pharmacists.

■ Describe the characteristics of medi-cations recently approved for the management of pain.

■ Discuss the clinical impact of recent published data describing the risks and benefits of analgesics.

prehensive, population-level strategy and provides a blueprint for moving forward. Key elements of the blueprint include1:

■ Reducing legal, regulatory, reimbursement, and cultural barriers to access.

■ Educating the public about the prevention, treatment, and self-management of pain.

■ Improving professional education across the spectrum of disciplines and throughout the continuum of undergradu-ate, graduate, and continuing health professions training.

■ Focusing pain research efforts at the National Institutes of Health and coordinating that research with other gov-ernment agencies and the private sector to speed develop-ment of new therapies, foster interdisciplinary approach-es, increase longitudinal research of people in pain, and increase the number of pain researchers.The IOM recommended that continuing education and

training for health professionals address gaps in knowledge and competencies related to pain assessment and manage-ment, cultural attitudes about pain, negative and ill-informed attitudes about people with pain, and stereotyping and biases

The IOM report supported the position that “in many cas-es, chronic pain is a disease in its own right.” Such an under-standing of pain calls for increased attention to the treatment of pain by the health care system and in health professionals’ education. The report calls for pain treatment and research “with the same vigor expended on other serious and disabling chronic conditions.”1

The IOM report issued a call to action for a cultural trans-formation in the manner in which pain is researched and man-aged on a systematic and individual level. Although many of the recommendations must be addressed on a systematic level, pharmacists can engage in many activities to improve the man-agement of patients with pain. The report recommends a com-

most effective analgesics and are also associated with abuse and diversion “a conundrum.”1 The misuse and abuse of opi-oids is a growing and important public health problem with a number of serious consequences. For example, the number of deaths associated with opioid overdoses has risen dramati-cally during the previous decade (Figure 2).5 Thus, the needs of patients in pain must be carefully balanced with the need to prevent inappropriate use of these agents.

Several strategies have been advanced that attempt to ensure that analgesics are available for patients who benefit from them while reducing their risks. A recent systemwide de-velopment has been the action by FDA to create a REMS for all long-acting and extended-release opioids.

Improper use of any opioid can result in serious conse-quences. However, FDA stated that the proposed REMS did not focus on immediate-release products because a long-acting or extended-release opioid product may result in even greater risk than an immediate-release opioid product if used by a per-son for whom it was not prescribed or if used improperly. The increased risk occurs because the amount of opioid contained in an extended-release tablet can be much greater than the amount of opioid contained in an immediate-release product and because long-acting opioids can take much longer to be cleared out of the body.6 The list of opioid products that are

that contribute to disparities in pain care.The report recommends increasing the number of health

professionals with advanced expertise in pain care and spe-cifically calls for pharmacists to receive advanced training. The IOM’s findings and recommendations are grouped by is-sues in Table 2.

New developments in managing painA number of developments occurred in 2011 and early 2012 that affect pain management, including development of a risk evaluation and mitigation strategy (REMS) program for long-acting and extended-release opioid analgesics, new research about the risk versus benefit equation for analgesics, and the entry of several new agents into the market.

ReMs for opioidsA major issue facing the pain management community is that although effective pain-relieving agents exist, their use is limited by their risks. Among the most prominent risks are the cardiovascular and gastrointestinal risks associated with NSAIDs, risk of hepatotoxicity associated with acetamino-phen, and risks of misuse, abuse, and diversion with opioids.

The IOM report calls the fact that opioids are among the

required to have a REMS can be found at www.fda.gov/Drugs/DrugSafety/InformationbyDrugClass/ucm251735.htm.

In April 2011, FDA announced the specific elements that will be required: All manufacturers of long-acting and extend-ed-release opioids must ensure that training is provided to prescribers of these medications and develop information that prescribers can use when counseling patients about the risks and benefits of opioid use. Prescriber education will include information on weighing the risks and benefits of opioid ther-apy, choosing patients appropriately, managing and monitor-ing patients, and counseling patients on the safe use of these drugs. In addition, prescribers will receive training to recog-nize evidence of and potential for opioid misuse, abuse, and addiction.6 According to FDA, the REMS program is focused on prescriber education because it is intended to reduce the potential for serious adverse outcomes resulting from inap-propriate prescribing and misuse, abuse, and diversion while ensuring that patients with legitimate need for these drugs continue to have appropriate access to them.6

The REMS will include educational materials that pre-scribers can provide to patients on how to use and store these products safely. Prescribers will be educated to properly coun-sel patients on safe use and the responsibilities associated with using these products, and patients will receive medica-tion guides when they pick up their prescriptions. (Medication guides are designed to provide information in patient friendly language about the medication’s risks and how to use the med-ication safely.6)

FDA notes that several factors were considered when de-veloping the requirements for the REMS. Designing the REMS in a way that it does not steer prescribers away from the long-acting and extended-release opioids to medications that are less appropriate for patients (such as immediate-release opi-oids that are not covered by the REMS) is important. Ensuring that patient access to needed medications is maintained while the REMS is being implemented is also critical. The REMS is designed so that if properly implemented, it can help improve patient care by improving communication.

FDA is implementing the REMS in a stepwise fashion to minimize the impact and burden on the health care system and patients. At this time, the education program is voluntary for health care providers. FDA is working with lawmakers with the goal of adding an education requirement to the DEA

licensure process. If such a requirement is implemented, it would be mandatory for licensure and would circumvent the need to create a separate registration system.6

Understanding REMSThe Food and Drug Administration Amendments Act of 2007 (FDAAA) authorized FDA to require REMSs for medications or medication classes with known serious risks.7 The law gave FDA the authority to determine whether a REMS is necessary to ensure that the benefits of a drug or biological product outweigh its risks. REMSs replaced the previously existing risk management programs called Risk Minimization Action Plans (RiskMAPs). An important distinction between the two programs is that FDA did not have authority to require or enforce a RiskMAP after product approval. Under FDAAA, FDA has the authority to require a REMS as part of the approval process for a new medication or postapproval if the agency becomes aware of new safety information about serious risks associated with the use of the medication after it is on the market.

As defined by the law, a REMS may include a medication guide, a patient package insert, a communication plan, and other elements to assure safe use (ETASUs). ETASUs, which must include goals to mitigate a specific serious risk listed in the labeling of the drug, may include the following requirements7:

■ Health care providers who prescribe the drug have particular training or experience or are specially certified.

■ Pharmacies, practitioners, or health care settings that dispense the drug are specially trained and/or certified.

■ The drug is dispensed to patients only in certain health care set-tings, such as hospitals (i.e., through a restricted distribution pro-gram).

■ The drug is dispensed to patients with evidence or other documen-tation of safe use conditions, such as laboratory test results.

■ Each patient using the drug is subject to certain monitoring. ■ Each patient using the drug is enrolled in a registry. ■ Physicians who prescribe and/or pharmacists who dispense the

drug are enrolled in a registry.If FDA deems that a REMS is necessary, the agency directs manu-

facturers to create a REMS with specific elements and the manu-facturers are required to comply. REMS programs vary from one another to address the specific issues for each medication, although brand and generic companies generally use a single, shared system. Manufacturers are responsible for implementing the system and working with FDA to assess and monitor outcomes of the system. FDA maintains a list of currently approved REMS at www.fda.gov/Drugs/DrugSafety/PostmarketDrugSafetyInformationforPatient-sandProviders/ucm111350.htm.

Taking another look at the risk: Benefit equation for NsAiDsAlthough NSAIDs are generally well demonstrated to be asso-ciated with risk of gastrointestinal and renal adverse events, evidence surrounding the cardiovascular safety of these agents has been evolving. Selective nonsteroidal agents (i.e., the cyclooxygenase [COX]-2 inhibitors) have been shown to be associated with adverse cardiovascular events, which led to the removal of rofecoxib from the market in 2004 and valdecoxib in 2005. Some but not all studies have found ce-lecoxib to have a slightly elevated risk, but it has remained on the market.8 Questions have remained about the cardio-vascular safety of nonselective NSAIDs such as ibuprofen and naproxen.

A 2011 systematic review looked at controlled studies pub-lished between 1985 and 2010 and reported on the cardiovas-cular risks associated with NSAID use. This review concluded that the impact of NSAIDs on cardiovascular risk varies from medication to medication. Naproxen (all doses) and low-dose ibuprofen were found to have the lowest cardiovascular risk, whereas rofecoxib and diclofenac had the highest risk. The risk associated with ibuprofen rose with increasing dosages. Etori-coxib, etodolac, and indomethacin were also found to have somewhat elevated risk.8 The review found that the level of risk associated with each NSAID remained constant regardless of patient background regarding cardiovascular risk.8

Other research has found that patients with established cardiovascular risk (older patients with hypertension and coronary artery disease) who use NSAIDs chronically for pain are at significantly increased risk of cardiovascular events. For example, one study that followed more than 22,000 patients for 2.7 years found that the risk of cardiovascular death was doubled in patients using NSAIDs chronically (compared with both intermittent users and never users).9

Questions remain regarding the comparative risks of vari-ous NSAIDs in different populations. The ongoing trial PRECI-SION (Prospective Randomized Evaluation of Celecoxib Inte-grated Safety versus Ibuprofen Or Naproxen) will hopefully provide more information on this issue.10 The study is designed to assess cardiovascular risk in patients at high risk who re-ceive chronic treatment with a COX-2 inhibitor or a nonselec-tive NSAID.10

New drug products for pain management Several new pain management medications were approved in 2011 and early 2012.

Two nonoral formulations of NSAIDs that were previously on the market were approved in 2011. Ketorolac trometh-amine nasal spray (Sprix—Luitpold) was approved for short-term treatment of moderate to moderately severe pain. It is the first intranasal NSAID to be approved in the United States. Sprix should not be used concomitantly with intramuscular/in-travenous or oral ketorolac, aspirin, or other NSAIDs or with probenecid or pentoxifylline. The dosage is 31.5 mg (one spray in each nostril) every 6 to 8 hours, up to 126 mg/day, for the shortest duration possible, up to 5 days total.11 (If other dos-age forms of ketorolac are used sequentially, the total length of treatment with ketorolac should not exceed 5 days.11)

Diclofenac sodium 1.5% topical solution (Pennsaid—Mallinckrodt) was approved for the treatment of signs and symptoms of osteoarthritis of the knees. The dosage is 40 drops per knee four times per day.12 This topical formulation of diclofenac is associated with a lower risk of gastrointestinal adverse events and abnormal laboratory parameters than oral diclofenac.13

Two long-acting gabapentin products were recently ap-proved. Gabapentin enacarbil extended-release 600 mg (Hori-zant—GlaxoSmithKline) was approved for treating restless leg syndrome in 2011 and received approval for the treatment of postherpetic neuralgia in June 2012. This medication should

be taken in the evening with food. Gabapentin extended re-lease (Gralise—Depomed) 300 and 600 mg was approved for the treatment of postherpetic neuralgia. It is the first once-dai-ly medication approved for this indication. This medication can be titrated upward as needed.14

Tapentadol extended release (Nucynta ER—Janssen) was approved for moderate to severe chronic pain.15 Tapentadol is the second combination mu-opioid receptor agonist and mono-amine reuptake inhibitor to be approved.16 (Tramadol was the first drug in this class.) This medication is administered twice daily and is available in several dosages: 50, 100, 150, 200, and 250 mg.17

The morphine product Embeda (King), which included a naltrexone core that would be released if the product was crushed, chewed or dissolved, was voluntarily recalled from the market in 2011 as a result of stability issues.18 It remains uncertain if or when the product will be marketed again.18

Two new formulations of fentanyl were approved in 2011, fentanyl sublingual tablets (Abstral—ProStrakan) and fentan-yl nasal spray (Lazanda—Archimedes), and in January 2012, a sublingual spray formulation of fentanyl (Subsys—INSYS Therapeutics) was approved.19 All three products are used to manage breakthrough cancer pain in patients who are already using another opioid around the clock. None of these products should be used by patients who are not opioid tolerant.

Reformulated versions of immediate-release oxycodone (Oxecta—King) and extended-release oxycodone (OxyCon-tin—Purdue) were released. The reformulated versions form a gelatinous mass if crushed, which prevents injection and snorting of the product. Available data indicate that abuse of these products has decreased significantly following the re-lease of the reformulations.20

An extended-release formulation of hydromorphone (Exal-go—Mallinckrodt) was released. This product fills the void left by the withdrawal of Palladone (extended-release hydromor-phone; Purdue), which was removed from the market because coadministration with alcohol resulted in immediate release of the entire hydromorphone dose.21 Exalgo is available in 8, 12, and 16 mg tablets and is administered once daily.22

A buprenorphine transdermal patch (Butrans—Purdue) was recently approved for managing moderate to severe chron-ic pain in patients requiring a continuous, around-the-clock opioid analgesic for an extended period of time. This agent is a partial mu agonist, weak kappa antagonist, agonist at delta opioid receptors, and a partial agonist at nociceptin (ORL-1) receptors. This receptor binding profile may help prevent the development of hyperalgesia.23 Butrans patches are available in 5, 10, and 20 mcg/hour formulations and are applied once every 7 days. Dosages above 20 mcg/hour have been associ-ated with increased risk of QT prolongation. It takes 3 days for the medication to reach steady state; thus, a gap of at least 3 days should be allowed between dosage adjustments.24

Communicating with patientsBecause medications are widely used in pain management and proper care requires consistent monitoring of analgesic

efficacy balanced with monitoring for potential for adverse events, it is natural that pharmacists, the “medication ex-perts” on the health care team, should be involved in pain management. Regardless of practice setting, informed phar-macists who understand how to assess pain, are familiar with the treatment options for pain, and are adept at monitoring response to treatment can play a critical role in managing pain.

Pharmacists can play an active role in implementing rec-ommendations from the IOM, including the following1:

■ Promote and enable self-management of pain: Pharma-cists can work with and educate their patients to empow-er them to be informed health care consumers.

■ Develop strategies for reducing barriers to pain care: Pharmacists can assess their practices to identify pain care barriers and devise and implement strategies to ad-dress these barriers.

■ Support collaboration between pain specialists and pri-mary care clinicians, including referral to pain centers when appropriate: For patients whose pain care team includes both primary care providers and specialists, pharmacists can work to facilitate communication among the providers and share information so that all members of the team have information about the patient’s current prescription regimen. In addition, pharmacists can iden-tify patients whose pain is not being adequately managed and provide recommendations to current prescribers or make referrals when appropriate.

■ Provide consistent and complete pain assessments: Pharmacists can include regular assessments of patients’ responses to therapy as part of the ongoing monitoring that they perform when patients present at the pharmacy for their prescriptions.Pharmacists can play an important role in ongoing mon-

itoring of patients with chronic pain because they typically see patients face to face on a monthly basis. Current research suggests that pharmacists could take a more proactive role in managing patients receiving medications for pain. A recent survey of patients with chronic pain in a community pharma-cy found that although patients often do not discuss issues related to the use of analgesics with their pharmacists, they would like to. In addition, they reported that they would like the pharmacist to have more communication with their pre-scribers (Figure 3).25

Although few pharmacists currently have advanced train-ing in pain care, open-ended questions can be used to briefly assess patients and uncover issues that require further inter-vention. (Open-ended questions are those that cannot be an-swered with “yes” or “no.”) Such questions can include26 How well are you doing with your pain medications?, Are you having any problems with constipation or sleepiness?, How is your pain right now?, Where do you hurt?, What makes the pain bet-ter?, What makes the pain worse?, What drugs have worked in the past?, and How often do you think you need pain medica-tion?

Although pain rating scales (e.g., asking patients to rate their pain on a scale from 0 to 10) can have a role in assess-

ing pain, questions that assess a patient’s function are likely to yield greater insight regarding the value of a treatment for the patient. If a patient’s functionality and ability to perform activities of daily living does not improve as a result of treat-ment, then other interventions should be explored. Consider-ing a number of possible explanations for the poor response to treatment, including the need to switch medications, the need to increase dosage, the possibility that the patient is misusing/abusing the medication, and the possibility that the patient has developed opioid-induced hyperalgesia is important.

Pharmacists are encouraged to educate patients so that they understand risks associated with pain management medi-cations and how to use these products safely. In a 2008 sur-vey of individuals reporting nonmedical use of pain relievers, 56% reported receiving the medication free from a friend or relative. Another 9% bought the medication from a friend or relative, and 5% took it from a friend or relative without ask-ing.27 Patients who receive controlled substances should be instructed to never share the medication and to store the medi-cation in a place where others will not have access to it. Many experts recommend storing the medications in a safe or lock box. Pharmacists should also review the risks of the medica-tion, including the potential for addiction, and requirements for safe use of the medication.

Finally, pharmacists can investigate and work to resolve pain-related medication problems when providing medication therapy management (MTM). They can be active participants on interdisciplinary pain care teams, by sharing drug therapy knowledge and providing recommendations and support to re-solve problems identified during MTM services.

1. Change ibuprofen to celecoxib2. Start immediate release hydromorphone for breakthrough

pain3. Reassess appropriateness of regimen for diabetic neuropa-

thy4. Increase dosage of controlled-release hydromorphone

The correct answer is choice 3. The appropriateness of the current treatment should be reassessed. Although patients with diabetic neuropathy may respond to opioid therapy, mechanis-tically, NSAIDs will likely provide little benefit. An adjuvant an-algesic that is indicated for the treatment of neuropathic pain should be considered. Treatment guidelines released in 2011 state that pregabalin is established as effective for the treat-ment of painful diabetic neuropathy. Other agents considered “probably effective” include venlafaxine, duloxetine, amitrip-tyline, gabapentin, valproate, capsaicin, and the opioids mor-phine, tramadol, and controlled-release oxycodone.28

While choice 3 is the most correct answer, the other op-tions should also receive consideration. Because of the pa-tient’s age, she is at risk for gastrointestinal adverse events from ibuprofen. Potential appropriate changes to the regimen would be to replace the ibuprofen with celecoxib and/or add an immediate-release version of hydromorphone for breakthrough pain. However, because the patient reports pain that appears to be neuropathic in nature, adding an agent such as a gabapenti-noid that is effective for neuropathic pain may be more appro-priate before increasing the dosage of the controlled-release hydromorphone.

Case 2A 37-year-old man reporting low back pain routinely brings in a new prescription for controlled-release oxycodone 5 to 6 days before his previous prescription should be finished. What is the best strategy for addressing this situation?1. Refill the prescription2. Call the prescriber3. Call police4. Assess pain

The correct answer is choice 4, although choice 2 could also be considered, depending on the relationship with the pa-tient. Many pharmacists report that their initial concern when presented with an early refill request for a controlled substance is that the patient is abusing or diverting the medication, and pharmacists may question the legitimacy of the prescription. However, the underlying reasons for the early refill request should be explored with the patient before proceeding with another course of action. Managing early refills for controlled substances can be challenging and time consuming. However, discussing the situation with the patient is important; each patient’s situation is unique, and exploring the issue with the patient can help uncover the underlying issue, whether it re-lates to uncontrolled pain, misuse abuse or diversion of the substance, or some other issue (e.g., a patient taking the medi-cation too quickly because of a misunderstanding of dosing in-structions).29

ConclusionThe 2011 IOM report, Relieving pain in America: A blueprint for transforming prevention, care, education, and research, issued a call to action for a cultural transformation to improve pain management in the United States. Many of the report’s recommendations included activities that pharmacists can implement in their current practice settings.

One of the primary challenges that pharmacists must ad-dress in their pain management activities is balancing the need to effectively relieve pain with the need to manage the risks of analgesic medications. New tools and information to manage these risks continually become available. In addition to familiarizing themselves with the latest data regarding the risks associated with analgesic medications, pharmacists can partake in the provider education program through the class-wide REMS for long-acting and extended-release opioids.

Finally, several new analgesic agents were approved in 2011. Pharmacists can familiarize themselves with the char-acteristics of these agents so that they are prepared to edu-cate both patients and other members of the health care team regarding appropriate use. By taking these steps and working to inform and educate themselves, their patients, and other health care providers, pharmacists can play a critical role in driving the transformation of pain care called for by the IOM.
