reformulated extended-release tablet (Opana ER)

  • Opana ER was discontinued from market at the request of FDA owing to a significant shift in route of abuse from nasal to injection following the product’s reformulation Injection abuse of reformulated
  • Opana ER has been associated with a serious outbreak of HIV, hepatitis C, and thrombotic microangiopathy

Moderate-to-Severe Pain

Acute pain

  • Immediate-release tablets are indicated for acute moderate-to-severe pain where pain is severe enough to require an opioid analgesic and for which alternative therapies are inadequate
  • Opioid-naive patients (immediate-release): 10-20 mg PO q4-6 hr PRN initially, then titrated as warranted (may start with 5-mg increments)

Chronic Severe Pain

Extended-release oxymorphone is indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate

Extended-release tablet initial dosing

  • Patients who are opioid-naive or not opioid-tolerant
    • 5 mg PO q12hr initially, then titrated in increments of 5-10 mg q12hr every 3-7 days to level that provides adequate analgesia and minimizes side effects
  • Patients who are opioid-tolerant
    • Opioid-tolerant definition: Patients who are receiving, for 1 week or longer, at least 60 mg/day PO morphine, 25 mcg/hr transdermal fentanyl, 30 mg/day PO oxycodone, 8 mg/day PO hydromorphone, 25 mg/day PO oxymorphone, or an equianalgesic dose of another opioid
    • Conversion from immediate-release to extended-release oxymorphone: Administer one-half of total immediate-release daily dose as extended-release q12hr
    • Conversion from other opioids: Refer to equianalgesic recommendations within the prescribing information

Dosage Modifications

Renal impairment

  • Immediate-release tablet; CrCl <50 mL/min: Initiate therapy at lowest dose (eg, 5 mg); titrate to effect slowly; monitor
  • Extended-release tablet
    • CrCl <50 mL/min (opioid-naïve): Initiate with 5 mg PO q12hr
    • CrCl <50 mL/min (prior opioid therapy): Initiate at 50% lower than the starting dose for a patient with normal hepatic function and titrate slowly

Hepatic impairment

  • Mild; immediate-release or injection: Initiate therapy at lowest dose; titrate to effect slowly; monitor
  • Moderate to severe: Contraindicated
  • Extended-release
    • Mild (opioid-naïve): Initiate with 5 mg PO q12hr
    • Mild (prior opioid therapy): Initiate at 50% lower than the starting dose for a patient with normal hepatic function and titrate slowly
    • Moderate or severe: Contraindicated

Dosing Considerations

Immediate-release tablets

  • Limitations of use
    • Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, reserve use when alternative treatment options (eg, nonopioid analgesics, opioid/opioid antagonist combination products) have not been tolerated, or are not expected to be tolerated, or have not provided adequate analgesia, or are not expected to provide adequate analgesia

Extended-release tablets

  • Limitations of use
    • Because of risks of addiction, abuse, and misuse with opioids, even at recommended doses, and because the greater risks of overdose and death with extended-release formulations, reserve for use in patients for whom alternative treatment options (eg, nonopioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient pain management
    • Extended-release formulations are not indicated as an as-needed (prn) analgesic

Access to naloxone for opioid overdose

  • Assess need for naloxone upon initiating and renewing treatment
  • Consider prescribing naloxone
    • Based on patient’s risk factors for overdose (eg, concomitant use of CNS depressants, a history of opioid use disorder, prior opioid overdose); presence of risk factors should not prevent proper pain management
    • Household members (including children) or other close contacts at risk for accidental ingestion or overdose
  • Consult patients and caregivers on the following:
    • Availability of naloxone for emergency treatment of opioid overdose
    • Ways differ on how to obtain naloxone as permitted by individual state dispensing and prescribing requirements or guidelines (eg, by prescription, directly from a pharmacist, as part of a community-based program)

Safety and efficacy not established

Steady-state plasma concentrations are ~40% higher in elderly individuals

Initiate with lowest dose; consider less frequent dosing

            Warnings

            Black Box Warnings

            Opioid analgesic risk evaluation and mitigation strategy (REMS)

            • To ensure that benefits of opioid analgesics outweigh risks of addiction, abuse, and misuse, the Food and Drug Administration (FDA) has required a REMS for these products; under requirements of the REMS, drug companies with approved opioid analgesic products must make REMS-compliant education programs available to healthcare providers
            • Healthcare providers are strongly encouraged to
              • Complete a REMS-compliant education program
              • Counsel patients and/or their caregivers, with every prescription, on safe use, serious risks, storage, and disposal of these products
              • Emphasize to patients and their caregivers the importance of reading the Medication Guide every time it is provided by their pharmacist
              • Consider other tools to improve patient, household, and community safety

            Addiction, abuse, and misuse

            • Risk of opioid addiction, abuse, and misuse, which can lead to overdose and death
            • Assess each patient’s risk prior to prescribing and monitor all patients regularly for the development of these behaviors or conditions

            Life-threatening respiratory depression

            • Serious, life-threatening, or fatal respiratory depression may occur
            • Monitor for respiratory depression, especially during initiation or following a dose increase
            • Instruct patients to swallow tablet/capsule whole; crushing, chewing, or dissolving can cause rapid release and absorption of a potentially fatal dose

            Accidental exposure

            • Accidental of even 1 dose, especially by children, can result in a fatal overdose

            Neonatal opioid withdrawal syndrome

            • Prolonged use during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts
            • Syndrome presents as irritability, hyperactivity and abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea and failure to gain weight
            • Onset, duration, and severity of neonatal opioid withdrawal syndrome vary based on the specific opioid used, duration of use, timing and amount of last maternal use, and rate of elimination of the drug by the newborn
            • If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available

            Interaction with central nervous system (CNS) depressants

            • Coadministration with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death
            • Reserve concomitant prescribing for use in patients for whom alternative treatment options are inadequate; limit dosages and durations to the minimum required; and follow patients for signs and symptoms of respiratory depression and sedation
            • Instruct patients not to consume alcoholic beverages or use alcohol-containing drug products while taking morphine due to risk of additive sedation and respiratory depression
            • Co-ingestion of alcohol may cause rapid release of opioid content from long-acting tablet/capsule and result in increased plasma levels and a potentially fatal overdose

            Contraindications

            Significant respiratory depression

            Acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment

            Known or suspected GI obstruction, including paralytic ileus

            Hypersensitivity

            Moderate-to-severe hepatic impairment

            Cautions

            Use caution in patients with acute pancreatitis, Addison disease, benign prostatic hyperplasia, cardiac arrhythmias, central nervous system (CNS) depression, drug abuse or dependence, emotional lability, gallbladder disease, gastrointestinal (GI) disorder, pseudomembranous colitis, GI surgery, head injury, hypothyroidism or untreated myxedema, intracranial hypertension, brain tumor, toxic psychosis, urethral stricture, urinary tract surgery, seizures, acute alcoholism, delirium tremens, shock, cor pulmonale, chronic pulmonary disease, emphysema, kyphoscoliosis, severe obesity, renal or hepatic impairment, elderly or debilitated patients

            Thrombocytopenia purpura resulting in kidney failure or death has been reported when extended-release tablets are dissolved and injected IV

            May obscure diagnosis of abdominal conditions

            Therapy may cause severe hypotension including orthostatic hypotension and syncope in ambulatory patients; there is increased risk in patients whose ability to maintain blood pressure has already been compromised by a reduced blood volume or concurrent administration of certain CNS depressant drugs (eg, phenothiazines or general anesthetics); monitor patients for signs of hypotension after initiating or titrating dosage; in patients with circulatory shock, therapy may cause vasodilation that can further reduce cardiac output and blood pressure; avoid therapy in patients with circulatory shock

            In patients who may be susceptible to intracranial effects of CO2 retention (eg, those with evidence of increased intracranial pressure or brain tumors), therapy may reduce respiratory drive, and resultant CO2 retention can further increase intracranial pressure; monitor such patients for signs of sedation and respiratory depression, particularly when initiating therapy; opioids may obscure clinical course in a patient with a head injury; avoid the use in patients with impaired consciousness or coma

            Contraindicated in patients with known or suspected gastrointestinal obstruction, including paralytic ileus; may cause spasm of sphincter of Oddi; opioids may cause increases in serum amylase; monitor patients with biliary tract disease, including acute pancreatitis, for worsening symptoms

            Therapy may increase frequency of seizures in patients with seizure disorders and in other clinical settings associated with seizures; monitor patients for worsened seizure control during therapy

            Warn patients not to drive or operate dangerous machinery unless they are tolerant to effects of drug and know how they will react to medication

            While serious, life-threatening, or fatal respiratory depression can occur at any time during therapy, risk is greatest during initiation of therapy or following dosage increase; monitor patients closely for respiratory depression, especially within first 24 to 72 hr of initiating therapy with and following dosage increases; accidental ingestion of even one dose, especially by children, can result in respiratory depression and death due to overdose of opioid

            Opioids can cause sleep-related breathing disorders including central sleep apnea (CSA) and sleep-related hypoxemia; opioid use increases risk of CSA in a dose-dependent fashion; in patients who present with CSA, consider decreasing opioid dosage using best practices for opioid taper

            Use in patients with acute or severe bronchial asthma in an unmonitored setting or in absence of resuscitative equipment is contraindicated; patients with significant chronic obstructive pulmonary disease or cor pulmonale, and with substantially decreased respiratory reserve, hypoxia, hypercapnia, or pre-existing respiratory depression are at increased risk of decreased respiratory drive including apnea, even at recommended dosages

            Life-threatening respiratory depression is more likely to occur in elderly, cachectic, or debilitated patients because they may have altered pharmacokinetics or altered clearance compared to younger, healthier patients; monitor closely

            Do not abruptly discontinue therapy in a patient physically dependent on opioids; when discontinuing therapy, in a physically dependent patient, gradually taper the dosage; rapid tapering in a patient physically dependent on opioids may lead to a withdrawal syndrome and return of pain

            Cases of adrenal insufficiency reported with opioid use, more often following greater than one month of use; symptoms may include nausea, vomiting, anorexia, fatigue, weakness, dizziness, and low blood pressure; if adrenal insufficiency is diagnosed, treat with physiologic replacement doses of corticosteroids; wean patient off of opioid to allow adrenal function to recover and continue corticosteroid treatment until adrenal function recovers; other opioids may be tried as some cases reported use of a different opioid without recurrence of adrenal insufficiency

            Use caution when selecting dosage for an elderly patient, usually starting at low end of dosing range, reflecting greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy; because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and may be useful to monitor renal function

            Opioid pharmacokinetics may be altered in patients with renal failure; clearance may be decreased and metabolites may accumulate much higher plasma levels in patients with renal failure as compared to patients with normal renal function; start with a lower than normal dosage or with longer dosing intervals and titrate slowly while monitoring for signs of respiratory depression, sedation, and hypotension

            Schedule II opioid analgesics expose users to the risks of addiction, abuse, and misuse; there is a greater risk for overdose and death with extended-release opioids due to the larger amount of active opioid present

            Addiction, abuse, and misuse risks are increased in patients with a personal or family history of substance abuse or mental illness (eg, major depression); the potential for these risks should not, however, prevent the prescribing of proper pain management in any given patient; intensive monitoring is necessary

            Drug interaction overview

            • Monoamine oxidase inhibitors (MAOIs) may potentiate effects of opioid, opioid’s active metabolite, including respiratory depression, coma, and confusion; therapy should not be administered within 14 days of initiating or stopping MAOIs
            • Profound sedation, respiratory depression, coma, and death may result from concomitant administration with benzodiazepines or other CNS depressants (eg, non-benzodiazepine sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids, alcohol); because of these risks, reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate; if concomitant use with benzodiazepine or muscle relaxant is warranted, consider prescribing naloxone for the emergency treatment of opioid overdose
            • If an opioid analgesic is initiated in a patient already taking a benzodiazepine or other CNS depressant, prescribe a lower initial dose of the opioid analgesic, and titrate based on clinical response; follow patients closely for signs and symptoms of respiratory depression and sedation
            • Avoid use of mixed agonist/antagonist (eg, pentazocine, nalbuphine, and butorphanol) or partial agonist (eg, buprenorphine) analgesics in patients who are receiving a full opioid agonist analgesic; mixed agonist/antagonist and partial agonist analgesics may reduce analgesic effect and/or precipitate withdrawal symptoms; when discontinuing therapy in physically-dependent patient, gradually taper dosage; do not abruptly discontinue therapy in these patients
            • Cases of serotonin syndrome, a potentially life-threatening condition, reported with concomitant use of serotonergic drugs; this may occur within the recommended dosage range; the onset of symptoms generally occur within several hours to a few days of concomitant use, but may occur later than that; discontinue therapy immediately if serotonin syndrome is suspected
            • Coadministration with anticholinergic drugs may increase risk of urinary retention
            • Opioids may reduce efficacy of diuretics by inducing antidiuretic hormone release
            • Cimetidine can potentiate opioid-induced respiratory depression

            Opioid analgesic risk evaluation and mitigation strategy (REMS)

            • To ensure that benefits of opioid analgesics outweigh risks of addiction, abuse, and misuse, the Food and Drug Administration (FDA) has required a Risk Evaluation and Mitigation Strategy (REMS) for these products
            • Discuss the safe use, serious risks, and proper storage and disposal of opioid analgesics with patients and/or their caregivers every time these medicines are prescribed; use the following link to obtain the Patient Counseling Guide (PCG): www.fda.gov/OpioidAnalgesicREMSPCG
            • Emphasize to patients and their caregivers the importance of reading the Medication Guide that they will receive from their pharmacist every time an opioid analgesic is dispensed to them
            • Consider using other tools to improve patient, household, and community safety, such as patient-prescriber agreements that reinforce patient-prescriber responsibilities
            • To obtain further information on opioid analgesic REMS and for a list of accredited REMS CME/CE, call 1-800-503-0784, or log on to www.opioidanalgesicrems.com; the FDA Blueprint can be found at www.fda.gov/OpioidAnalgesicREMSBlueprint

            Patient access to naloxone for emergency treatment of opioid overdose

            • Assess potential need for naloxone; consider prescribing for emergency treatment of opioid overdose
            • Consult on availability and ways to obtain naloxone as permitted by individual state naloxone dispensing and prescribing requirements or guidelines
            • Educate patients regarding the signs and symptoms of respiratory depression and to call 911 or seek immediate emergency medical help in the event of a known or suspected overdose

            Pregnancy & Lactation

            Pregnancy

            Prolonged use of opioid analgesics during pregnancy can cause neonatal opioid withdrawal syndrome; there are no available data in pregnant women to inform a drug associated risk for major birth defects and miscarriage; published studies with morphine use during pregnancy have not reported a clear association with morphine and major birth defects

            Prolonged use of opioid analgesics during pregnancy for medical or nonmedical purposes can result in physical dependence in the neonate and neonatal opioid withdrawal syndrome shortly after birth; the onset, duration, and severity of neonatal opioid withdrawal syndrome vary based on specific opioid used, duration of use, timing and amount of last maternal use, and rate of elimination of drug by newborn; observe newborns for symptoms of neonatal opioid withdrawal syndrome and manage accordingly

            Observe newborns for symptoms of neonatal opioid withdrawal syndrome (eg, poor feeding, diarrhea, irritability, tremor, rigidity, and seizures), and manage accordingly

            Labor or delivery

            • Opioids cross placenta and may produce respiratory depression and psycho-physiologic effects in neonates; an opioid antagonist, such as naloxone, must be available for reversal of opioid induced respiratory depression in neonate; drug is not recommended for use in women during and immediately prior to labor, when use of shorter-acting analgesics or other analgesic techniques are more appropriate; opioid analgesics can prolong labor through actions that temporarily reduce strength, duration, and frequency of uterine contractions; however, this effect is not consistent and may be offset by an increased rate of cervical dilatation, which tends to shorten labor; monitor neonates exposed to opioid analgesics during labor for signs of excess sedation and respiratory depression

            Infertility

            • Due to effects of androgen deficiency, chronic use of opioids may cause reduced fertility in females and males of reproductive potential; it is not known whether effects on fertility are reversible

            Lactation

            Unknown if excreted in breast milk; many drugs, including some opioids, are excreted in human milk

            If opioid must be used; monitor infant closely for excess sedation and respiratory depression; withdrawal symptoms can occur when breastfeeding or maternal opioid is stopped

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA: Information not available.

            Oral Administration

            Take on empty stomach, at least 1 hr before or 2 hr after eating

            Do not stop abruptly if opioid tolerant; taper gradually to stop treatment

            Extended-release tablets

            • Swallow tablet whole; do not crush, chew, or dissolve
            • Altering tablet (ie, crushing, chewing, or dissolving) will result in uncontrolled delivery of oxymorphone and can lead to overdose or death

            Safe reduction or discontinuation

            • Do not abruptly discontinue in patients who may be physically dependent on opioids; rapid discontinuation in physically dependent patients has resulted in serious withdrawal symptoms, uncontrolled pain, and suicide; also associated with attempts treat their pain or withdrawal symptoms with illicit opioids
            • Consider all factors when decreasing dose or discontinuing therapy (eg, dose, duration of treatment, type of pain, patient’s physical and psychological profile)
            • Gradual tapering
              • There are no standard opioid tapering schedules that are suitable for all patients
              • Good clinical practice dictates a patient-specific plan to taper the dose of the opioid gradually
              • For patients who are physically opioid-dependent, initiate taper by small increment (eg, no greater than 10-25% of total daily dose) to avoid withdrawal symptoms, and proceed with dose-lowering at q2-4week interval
              • It may be necessary to provide lower dosage strengths to accomplish successful tapering
              • Reassess frequently to manage pain and withdrawal symptoms
              • When managing patients taking opioid analgesics, particularly those who have been treated for a long duration and/or with high doses for chronic pain, ensure that a multimodal approach to pain management, including mental health support (if needed), is in place before initiating tapering
              • Multimodal approach to pain management may optimize the treatment of chronic pain, and assist with successful tapering
            • Withdrawal symptoms
              • Restlessness, lacrimation, rhinorrhea, yawning, perspiration, chills, myalgia, and mydriasis
              • Other signs and symptoms also may develop, including irritability, anxiety, backache, joint pain, weakness, abdominal cramps, insomnia, nausea, anorexia, vomiting, diarrhea, or increased blood pressure, respiratory rate, or heart rate
              • If withdrawal symptoms arise, it may be necessary to pause the taper for a period of time or raise analgesic opioid dose, and then proceed with a slower taper
              • Monitor patients for any changes in mood, emergence of suicidal thoughts, or use of other substances

            WARNING: Oxymorphone has a risk for abuse and addiction, which can lead to overdose and death. Oxymorphone may also cause severe, possibly fatal, breathing problems. To lower your risk, your doctor should have you take the smallest dose of oxymorphone that works, and take it for the shortest possible time. See also How to Use section for more information about addiction.Ask your doctor or pharmacist if you should have naloxone available to treat opioid overdose. Teach your family or household members about the signs of an opioid overdose and how to treat it.The risk for severe breathing problems is higher when you start this medication and after a dose increase, or if you take the wrong dose/strength. Taking this medication with alcohol or other drugs that can cause drowsiness or breathing problems may cause very serious side effects, including death. Be sure you know how to take oxymorphone and what other drugs you should avoid taking with it. See also Drug Interactions section. Get medical help right away if any of these very serious side effects occur: slow/shallow breathing, unusual lightheadedness, severe drowsiness/dizziness, difficulty waking up.Do not drink alcohol or take any products that contain alcohol while taking this medication.

To prevent withdrawal, your doctor may lower your dose slowly. Tell your doctor or pharmacist right away if you have any withdrawal symptoms such as restlessness, mental/mood changes (including anxiety, trouble sleeping, thoughts of suicide), watering eyes, runny nose, nausea, diarrhea, sweating, muscle aches, or sudden changes in behavior.When this medication is used for a long time, it may not work as well. Talk with your doctor if this medication stops working well.Though it helps many people, this medication may sometimes cause addiction.
