  • BOXED WARNING (What is this?)

    WARNING: ADDICTION, ABUSE, AND MISUSE; RISK EVALUATION AND MITIGATION STRATEGY (REMS); LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL INGESTION; NEONATAL OPIOID WITHDRAWAL SYNDROME; INTERACTION WITH ALCOHOL; and RISKS FROM CONCOMITANT USE WITH BENZODIAZEPINES OR OTHER CNS DEPRESSANTS

    Addiction, Abuse, and Misuse
    Oxymorphone Hydrochloride Tablets exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Assess each patients risk prior to prescribing Oxymorphone Hydrochloride Tablet, and monitor all patients regularly for the development of these behaviors and conditions     [see Warnings and Precautions (5.1)].

    Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS):
    To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse, and misuse, the Food and Drug Administration (FDA) has required a REMS for these products [see Warnings and Precautions (5.2)]. Under the 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, and
    • consider other tools to improve patient, household, and community safety.

    Life-threatening Respiratory Depression

    Serious, life-threatening, or fatal respiratory depression may occur with use of Oxymorphone Hydrochloride Tablets. Monitor for respiratory depression, especially during initiation of Oxymorphone Hydrochloride Tablets or following a dose increase [see Warnings and Precautions (5.3)].
    Accidental Ingestion
    Accidental ingestion of even one dose of Oxymorphone Hydrochloride Tablets, especially by children, can result in a fatal overdose of oxymorphone     [see Warnings and Precautions (5.3)].
    Neonatal Opioid Withdrawal Syndrome
    Prolonged use of Oxymorphone Hydrochloride Tablets 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. 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     [see Warnings and Precautions (5.4)].
    Interaction with Alcohol
    Instruct patients not to consume alcoholic beverages or use prescription or non-prescription products that contain alcohol while taking Oxymorphone Hydrochloride Tablets. The co-ingestion of alcohol with Oxymorphone Hydrochloride Tablets may result in increased plasma levels and a potentially fatal overdose of oxymorphone     [see Warnings and Precautions (5.5)].
    Risks From Concomitant Use With Benzodiazepines Or Other CNS Depressants
    Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death [see Warnings and Precautions (5.5), Drug Interactions (7)].

    • Reserve concomitant prescribing of Oxymorphone Hydrochloride Tablets and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate.
    • Limit dosages and durations to the minimum required.
    • Follow patients for signs and symptoms of respiratory depression and sedation.

  • 1 INDICATIONS & USAGE


    Oxymorphone Hydrochloride Tablets are indicated for the management of acute pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate.
    Limitations of Use
    Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses [see Warnings and Precautions (5.1)], reserve Oxymorphone Hydrochloride Tablets for use in patients for whom alternative treatment options [e.g., non-opioid analgesics or opioid combination products]:

    • Have not been tolerated, or are not expected to be tolerated,
    • Have not provided adequate analgesia, or are not expected to provide adequate analgesia
  • 2 DOSAGE & ADMINISTRATION

    2.1 Important Dosage and Administration Instructions

    Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and Precautions (5)].

    Initiate the dosing regimen for each patient individually, taking into account the patient's severity of pain, patient response, prior analgesic treatment experience, and risk factors for addiction, abuse, and misuse [see Warnings and Precautions (5.1)].

    Monitor patients closely for respiratory depression, especially within the first 24-72 hours of initiating therapy and following dosage increases with Oxymorphone Hydrochloride Tablets and adjust the dosage accordingly [see Warnings and Precautions (5.3)].

    Oxymorphone Hydrochloride Tablet should be administered on an empty stomach, at least one hour prior to or two hours after eating [see Clinical Pharmacology (12.3)].

    To avoid medication errors, prescribers and pharmacists must be aware that oxymorphone is available as both immediate-release 5 mg and 10 mg tablets and extended-release 5 mg and 10 mg tablets [see Dosage Forms and Strengths (3)].


    2.2 Initial Dosage


    Use of Oxymorphone Hydrochloride Tabletsas the first Opioid Analgesic
    Initiate treatment with Oxymorphone Hydrochloride Tablets in a dosing range of 10 to 20 mg every 4 to 6 hours as needed for pain.

    Do not initiate treatment with doses higher than 20 mg because of the potential serious adverse reactions [see Clinical Studies (14.1)].
    Conversion from Other Opioids to Oxymorphone Hydrochloride Tablets
    There is inter-patient variability in the potency of opioid drugs and opioid formulations. Therefore, a conservative approach is advised when determining the total daily dosage of Oxymorphone Hydrochloride Tablets. It is safer to underestimate a patient’s 24-hour Oxymorphone Hydrochloride Tablets dosage than to overestimate the 24-hour Oxymorphone Hydrochloride Tablets dosage and manage an adverse reaction due to overdose.

    For conversion from other opioids to Oxymorphone Hydrochloride Tablets, physicians and other healthcare professionals are advised to refer to published relative potency information, keeping in mind that conversion ratios are only approximate. In general, it is safest to start Oxymorphone Hydrochloride Tablets therapy by administering half of the calculated total daily dose of Oxymorphone Hydrochloride Tablets in 4 to 6 equally divided doses, every 4-6 hours. The initial dose of Oxymorphone Hydrochloride Tablets can be gradually adjusted until adequate pain relief and acceptable side effects have been achieved.

    Conversion from Parenteral Oxymorphone to Oxymorphone Hydrochloride Tablets
    Given Oxymorphone Hydrochloride tablet’s absolute oral bioavailability of approximately 10%, patients receiving parenteral oxymorphone may be converted to Oxymorphone Hydrochloride Tablets by administering 10 times the patient’s total daily parenteral oxymorphone dose as Oxymorphone Hydrochloride Tablets, in four or six equally divided doses (e.g., [IV dose x 10] divided by 4 or 6). For example, approximately 10 mg of Oxymorphone Hydrochloride Tablets four times daily may be required to provide pain relief equivalent to a total daily IM dose of 4 mg oxymorphone. Due to patient variability with regard to opioid analgesic response, upon conversion patients should be closely monitored to ensure adequate analgesia and to minimize side effects.

    Conversion from Oxymorphone Hydrochloride Tablets to Extended-Release Oxymorphone
    The relative bioavailability of Oxymorphone Hydrochloride Tablets compared to extended-release oxymorphone is unknown, so conversion to extended-release tablets must be accompanied by close observation for signs of excessive sedation and respiratory depression.

    2.3 Dosage Modifications in Patients with Mild Hepatic Impairment

    Oxymorphone Hydrochloride Tablets is contraindicated in patients with moderate or severe hepatic impairment.

    Use Oxymorphone Hydrochloride Tablets with caution in patients with mild hepatic impairment, starting with the lowest dose (e.g., 5 mg) and titrating slowly while carefully monitoring for signs of respiratory and central nervous system depression [see Warnings and Precautions (5.3) and Clinical Pharmacology (12.3)].


    2.4 Dosage Modifications in Patients with Renal Impairment

    Use Oxymorphone Hydrochloride Tablets with caution in patients with creatinine clearance rates less than 50 mL/min., starting with the lowest dose (e.g., 5 mg) and titrating slowly while carefully monitoring for signs of respiratory and central nervous system depression [see Warnings and Precautions (5.3) and Clinical Pharmacology (12.3)].

    2.5 Dosage Modifications in Geriatric Patients

    Exercise caution in the selection of the starting dose of Oxymorphone Hydrochloride Tablets for an elderly patient by starting with the lowest dose (e.g., 5 mg) and titrate slowly while carefully monitoring for signs of respiratory and central nervous system depression [see Use in Specific Populations (8.5)].

    2.6 Dosage Modifications with Concomitant Use of Central Nervous System Depressants

    Oxymorphone Hydrochloride Tablets, like all opioid analgesics, should be started at one-third to one-half of the usual dose in patients who are concurrently receiving other central nervous system (CNS) depressants including sedatives or hypnotics, general anesthetics, phenothiazines, tranquilizers, and alcohol, because respiratory depression, hypotension and profound sedation, coma or death may result [see Warnings and Precautions (5.5) and Drug Interactions (7)]. When combined therapy with any of the above medications is considered, the dose of one or both agents should be reduced.

    2.7 Titration and Maintenance of Therapy



    Individually titrate Oxymorphone Hydrochloride Tablets to a dose that provides adequate analgesia and minimizes adverse reactions. Continually reevaluate patients receiving Oxymorphone Hydrochloride Tablets to assess the maintenance of pain control and the relative incidence of adverse reactions, as well as monitoring for the development of addiction, abuse, or misuse [see Warnings and Precautions (5.1)]. Frequent communication is important among the prescriber, other members of the healthcare team, the patient, and the caregiver/family during periods of changing analgesic requirements, including initial titration.

    If the level of pain increases after dosage stabilization, attempt to identify the source of increased pain before increasing the Oxymorphone Hydrochloride Tablets dosage. If unacceptable opioid-related adverse reactions are observed, consider reducing the dosage. Adjust the dosage to obtain an appropriate balance between management of pain and opioid-related adverse reactions.

    2.8 Safe Reduction or Discontinuation of Oxymorphone Hydrochloride Tablets

    Do not abruptly discontinue Oxymorphone Hydrochloride Tablets in patients who may be physically dependent on opioids. Rapid discontinuation of opioid analgesics in patients who are physically dependent on opioids has resulted in serious withdrawal symptoms, uncontrolled pain, and suicide. Rapid discontinuation has also been associated with attempts to find other sources of opioid analgesics, which may be confused with drug-seeking for abuse. Patients may also attempt to treat their pain or withdrawal symptoms with illicit opioids, such as heroin, and other substances.

    When a decision has been made to decrease the dose or discontinue therapy in an opioid-dependent patient taking Oxymorphone Hydrochloride Tablets, there are a variety of factors that should be considered, including the dose of Oxymorphone Hydrochloride Tablets the patient has been taking, the duration of treatment, the type of pain being treated, and the physical and psychological attributes of the patient. It is important to ensure ongoing care of the patient and to agree on an appropriate tapering schedule and follow-up plan so that patient and provider goals and expectations are clear and realistic. When opioid analgesics are being discontinued due to a suspected substance use disorder, evaluate and treat the patient, or refer for evaluation and treatment of the substance use disorder. Treatment should include evidence-based approaches, such as medication assisted treatment of opioid use disorder. Complex patients with comorbid pain and substance use disorders may benefit from referral to a specialist.

    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 on Oxymorphone Hydrochloride Tablets who are physically opioid-dependent, initiate the taper by a small enough increment (e.g., no greater than 10% to 25% of the total daily dose) to avoid withdrawal symptoms, and proceed with dose-lowering at an interval of every 2 to 4 weeks. Patients who have been taking opioids for briefer periods of time may tolerate a more rapid taper.

    It may be necessary to provide the patient with lower dosage strengths to accomplish a successful taper. Reassess the patient frequently to manage pain and withdrawal symptoms, should they emerge. Common withdrawal symptoms include 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 the dose of the opioid analgesic to the previous dose, and then proceed with a slower taper. In addition, monitor patients for any changes in mood, emergence of suicidal thoughts, or use of other substances.

    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 prior to initiating an opioid analgesic taper. A multimodal approach to pain management may optimize the treatment of chronic pain, as well as assist with the successful tapering of the opioid analgesic [see Warnings and Precautions (5.13), Drug Abuse and Dependence (9.3)].

    • Moderate or severe hepatic impairment [see Warnings and Precautions (5.15)].
  • 5 WARNINGS AND PRECAUTIONS

    5.1 Addiction, Abuse, and Misuse



    Oxymorphone Hydrochloride Tablets contains oxymorphone, a Schedule II controlled substance. As an opioid, Oxymorphone Hydrochloride Tablets exposes users to the risks of addiction, abuse, and misuse [see Drug Abuse and Dependence (9)].

    Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed Oxymorphone Hydrochloride Tablets . Addiction can occur at recommended dosages and if the drug is misused or abused.

    Assess each patient’s risk for opioid addiction, abuse, or misuse prior to prescribing Oxymorphone Hydrochloride Tablets , and monitor all patients receiving Oxymorphone Hydrochloride Tablets for the development of these behaviors and conditions. Risks are increased in patients with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (e.g., major depression). The potential for these risks should not, however, prevent the proper management of pain in any given patient. Patients at increased risk may be prescribed opioids such as Oxymorphone Hydrochloride Tablets , but use in such patients necessitates intensive counseling about the risks and proper use of Oxymorphone Hydrochloride Tablets along with intensive monitoring for signs of addiction, abuse, and misuse.

    Opioids are sought by drug abusers and people with addiction disorders and are subject to criminal diversion. Consider these risks when prescribing or dispensing Oxymorphone Hydrochloride Tablets. Strategies to reduce these risks include prescribing the drug in the smallest appropriate quantity and advising the patient on the proper disposal of unused drug [see Patient Counseling Information (17)]. Contact local state professional licensing board or state controlled substances authority for information on how to prevent and detect abuse or diversion of this product.

    5.2 Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS)

    To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse, and misuse, the Food and Drug Administration (FDA) has required a Risk Evaluation and Mitigation Strategy (REMS) for these products. Under the 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 do all of the following:

    • Complete a REMS-compliant education program offered by an accredited provider of continuing education (CE) or another education program that includes all the elements of the FDA  Education Blueprint for Health Care Providers Involved in the Management or Support of Patients with Pain.
    • 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. The Patient Counseling Guide (PCG) can be obtained at this link: 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 the 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.

    5.3 Life-Threatening Respiratory Depression


    Serious, life-threatening, or fatal respiratory depression has been reported with the use of opioids, even when used as recommended. Respiratory depression, if not immediately recognized and treated, may lead to respiratory arrest and death. Management of respiratory depression may include close observation, supportive measures, and use of opioid antagonists, depending on the patient’s clinical status [see Overdosage (10)]. Carbon dioxide (CO2) retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids.

    While serious, life-threatening, or fatal respiratory depression can occur at any time during the use of Oxymorphone Hydrochloride Tablets, the risk is greatest during the initiation of therapy or following a dosage increase. Monitor patients closely for respiratory depression, especially within the first 24-72 hours of initiating therapy with and following dosage increases of Oxymorphone Hydrochloride Tablets.

    To reduce the risk of respiratory depression, proper dosing and titration of Oxymorphone Hydrochloride Tablets are essential [see Dosage and Administration (2)]. Overestimating the Oxymorphone Hydrochloride Tablets dosage when converting patients from another opioid product can result in a fatal overdose with the first dose.

    Accidental ingestion of even one dose of Oxymorphone Hydrochloride Tablets, especially by children, can result in respiratory depression and death due to an overdose of oxymorphone.

    Opioids can cause sleep-related breathing disorders including central sleep apnea (CSA) and sleep-related hypoxemia. Opioid use increases the risk of CSA in a dose-dependent fashion. In patients who present with CSA, consider decreasing the opioid dosage using best practices for opioid taper [see Dosage and Administration (2.8)]

    5.4 Neonatal Opioid Withdrawal Syndrome


    Prolonged use of Oxymorphone Hydrochloride Tablets during pregnancy can result in withdrawal in the neonate. Neonatal opioid withdrawal syndrome, unlike opioid withdrawal syndrome in adults, may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. Observe newborns for signs of neonatal opioid withdrawal syndrome and manage accordingly. Advise pregnant women using opioids for a prolonged period of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available [see Use in Specific Populations (8.1), Patient Counseling Information (17)].

    5.5 Risks from Concomitant Use with Benzodiazepines or Other CNS Depressants



    Patients must not consume alcoholic beverages or prescription or non-prescription products containing alcohol while on Oxymorphone Hydrochloride Tablets therapy. The co-ingestion of alcohol with Oxymorphone Hydrochloride Tablets may result in increased plasma levels and a potentially fatal overdose of oxymorphone [see Clinical Pharmacology (12.3)].

    Profound sedation, respiratory depression, coma, and death may result from the concomitant use of Oxymorphone Hydrochloride Tablets with benzodiazepines or other CNS depressants (e.g., 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.

    Observational studies have demonstrated that concomitant use of opioid analgesics and benzodiazepines increases the risk of drug-related mortality compared to use of opioid analgesics alone. Because of similar pharmacological properties, it is reasonable to expect similar risk with the concomitant use of other CNS depressant drugs with opioid analgesics [see Drug Interactions (7)].

    If the decision is made to prescribe a benzodiazepine or other CNS depressant concomitantly with an opioid analgesic, prescribe the lowest effective dosages and minimum durations of concomitant use. In patients already receiving an opioid analgesic, prescribe a lower initial dose of the benzodiazepine or other CNS depressant than indicated in the absence of an opioid, and titrate based on clinical response. 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.
     
    Advise both patients and caregivers about the risks of respiratory depression and sedation when Oxymorphone Hydrochloride Tablets is used with benzodiazepines or other CNS depressants (including alcohol and illicit drugs). Advise patients not to drive or operate heavy machinery until the effects of concomitant use of the benzodiazepine or other CNS depressant have been determined. Screen patients for risk of substance use disorders, including opioid abuse and misuse, and warn them of the risk for overdose and death associated with the use of additional CNS depressants including alcohol and illicit drugs [see Drug Interactions (7), Patient Counseling Information (17)].

    5.6 Life-Threatening Respiratory Depression in Patients  with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients

    The use of Oxymorphone Hydrochloride Tablets in patients with acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment is contraindicated.

    Patients with Chronic Pulmonary Disease: Oxymorphone Hydrochloride Tablets -treated patients with significant chronic obstructive pulmonary disease or cor pulmonale, and those with a 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 of Oxymorphone Hydrochloride Tablets [see Warnings and Precautions (5.3)].
    Elderly, Cachectic, or Debilitated Patients: 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 [see Warnings and Precautions (8.5)].

    Monitor such patients closely, particularly when initiating and titrating Oxymorphone Hydrochloride Tablets and when Oxymorphone Hydrochloride Tablets is given concomitantly with other drugs that depress respiration [see Warnings and Precautions (5.3)]. Alternatively, consider the use of non-opioid analgesics in these patients.


    5.7 Anaphylaxis, Angioedema, and Other Hypersensitivity Reactions


    Potentially life-threatening hypersensitivity reactions, including anaphylaxis and angioedema, have occurred in patients treated with Oxymorphone Hydrochloride Tablets in the postmarket setting. The most commonly described clinical features in these reports were swelling of the face, eyes, mouth, lips, tongue, hands, and/or throat; dyspnea; hives, pruritus, and/or rash; and nausea/vomiting. If anaphylaxis or other hypersensitivity occurs, stop administration of Oxymorphone Hydrochloride Tablets immediately, discontinue Oxymorphone Hydrochloride Tablets permanently, and do not rechallenge with any formulation of oxymorphone. Advise patients to seek immediate medical attention if they experience any symptoms of a hypersensitivity reaction [see Patient Counseling Information (17)].

    5.8 Adrenal Insufficiency



    Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. Presentation of adrenal insufficiency may include non-specific symptoms and signs including nausea, vomiting, anorexia, fatigue, weakness, dizziness, and low blood pressure. If adrenal insufficiency is suspected, confirm the diagnosis with diagnostic testing as soon as possible. If adrenal insufficiency is diagnosed, treat with physiologic replacement doses of corticosteroids. Wean the patient off of the 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. The information available does not identify any particular opioids as being more likely to be associated with adrenal insufficiency.

    5.9 Severe Hypotension

    Oxymorphone Hydrochloride Tablets 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 (e.g., phenothiazines or general anesthetics) [see Warnings and Precautions (5.5) and Drug Interactions (7)]. Monitor these patients for signs of hypotension after initiating or titrating the dosage of Oxymorphone Hydrochloride Tablets. In patients with circulatory shock, Oxymorphone Hydrochloride Tablets may cause vasodilation that can further reduce cardiac output and blood pressure. Avoid the use of Oxymorphone Hydrochloride Tablets in patients with circulatory shock.

    5.10 Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness

    In patients who may be susceptible to the intracranial effects of CO2 retention (e.g., those with evidence of increased intracranial pressure or brain tumors), Oxymorphone Hydrochloride Tablets may reduce respiratory drive, and the resultant CO2 retention can further increase intracranial pressure. Monitor such patients for signs of sedation and respiratory depression, particularly when initiating therapy with Oxymorphone Hydrochloride Tablets.
    Opioids may also obscure the clinical course in a patient with a head injury. Avoid the use of Oxymorphone Hydrochloride Tablets in patients with impaired consciousness or coma.


    5.11 Risks of Use in Patients with Gastrointestinal Conditions


    Oxymorphone Hydrochloride Tablets is contraindicated in patients with known or suspected gastrointestinal obstruction, including paralytic ileus.

    The oxymorphone in Oxymorphone Hydrochloride Tablets may cause spasm of the sphincter of Oddi. Opioids may cause increases in serum amylase. Monitor patients with biliary tract disease, including acute pancreatitis for worsening symptoms.



    5.12 Increased Risk of Seizures in Patients with Seizure Disorders


    The oxymorphone in Oxymorphone Hydrochloride Tablets may increase the frequency of seizures in patients with seizure disorders, and may increase the risk of seizures occurring in other clinical settings associated with seizures. Monitor patients with a history of seizure disorders for worsened seizure control during Oxymorphone Hydrochloride Tablets therapy.

    5.13 Withdrawal


    Do not abruptly discontinue Oxymorphone Hydrochloride Tablets in a patient physically dependent on opioids. When discontinuing Oxymorphone Hydrochloride Tablets in a physically dependent patient, gradually taper the dosage. Rapid tapering of oxymorphone in a patient physically dependent on opioids may lead to a withdrawal syndrome and return of pain [see Dosage and Administration (2.8), Drug Abuse and Dependence (9.3)].

    Additionally, avoid the use of mixed agonist/antagonist (e.g., pentazocine, nalbuphine, and butorphanol) or partial agonist (e.g., buprenorphine) analgesics in patients who are receiving a full opioid agonist analgesic, including Oxymorphone Hydrochloride Tablets. In these patients, mixed agonist/antagonist and partial agonist analgesics may reduce the analgesic effect and/or may precipitate withdrawal symptoms [see Drug Interactions (7)].


    5.14 Risks of Driving and Operating Machinery


    Oxymorphone Hydrochloride Tablets may impair the mental or physical abilities needed to perform potentially hazardous activities such as driving a car or operating machinery. Warn patients not to drive or operate dangerous machinery unless they are tolerant to the effects of Oxymorphone Hydrochloride Tablets and know how they will react to the medication.

    5.15 Hepatic Impairment

    A study of extended-release oxymorphone tablets in patients with hepatic disease indicated greater plasma concentrations than in those with normal hepatic function [see Clinical Pharmacology (12.3)]. Use Oxymorphone Hydrochloride Tablets with caution in patients with mild impairment, starting with the lowest dose and titrating slowly while carefully monitoring for side effects [see Dosage and Administration (2.2, 2.3)]. Oxymorphone Hydrochloride Tablets is contraindicated in patients with moderate or severe hepatic impairment.

    Intervention:
    		Instruct patients not to consume alcoholic beverages or use prescription or non­prescription products containing alcohol while on Oxymorphone Hydrochloride Tablets therapy [see Clinical Pharmacology 12.3)].
    Benzodiazepines and Other Central Nervous System (CNS) Depressants
    Clinical Impact:
    		Due to additive pharmacologic effect, the concomitant use of benzodiazepines and other CNS depressants, including alcohol, can increase the risk of hypotension, respiratory depression, profound sedation, coma, and death.
    Intervention:
    		Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients closely for signs of respiratory depression and sedation [Warnings and Precautions (5.5)].
    Examples:
    		Benzodiazepines and other sedatives/hypnotics, anxiolytics tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids, alcohol.
    Serotonergic Drugs
    Clinical Impact:
    		The concomitant use of opioids with other drugs that affect the serotonergic neurotransmitter system has resulted in serotonin syndrome.
    Intervention:
    		If concomitant use is warranted, carefully observe the patient, particularly during treatment initiation and dose adjustment. Discontinue Oxymorphone Hydrochloride Tablets if serotonin syndrome is suspected.
    Examples:
    		Selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), triptans, 5-HT3 receptor antagonists, drugs that affect the serotonin neurotransmitter system (e.g., mirtazapine, trazodone, tramadol), certain muscle relaxants (i.e., cyclobenzaprine, metaxalone), monoamine oxidase (MAO) inhibitors (those intended to treat psychiatric disorders and also others, such as linezolid and intravenous methylene blue).
    Monoamine Oxidase Inhibitors (MAOIs)
    Clinical Impact:
    		MAOI interactions with opioids may manifest as serotonin syndrome or opioid toxicity (e.g., respiratory depression, coma) [see Warnings and Precautions (5.3)].

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    Prolonged use of opioid analgesics during pregnancy may cause neonatal opioid withdrawal syndrome [see Warnings and Precautions (5.4) and Clinical Considerations]. Data from randomized controlled trials with oxymorphone use in pregnant women during labor and delivery have been conducted. However, these studies were not designed to identify a drug-associated risk for major birth defects and miscarriage because oxymorphone exposure occurred after the first trimester. There are reports of respiratory depression in infants in some of these trials [see Clinical Considerations].

    In animal reproduction studies, reduced postnatal survival of pups and an increased incidence of stillborn pups were observed following oral treatment of pregnant rats with oxymorphone during gestation and through lactation at doses 2.4 and 12 times the human daily dose of 20 mg/day (HDD), respectively. Reduced fetal weights were observed with oral administration of oxymorphone to pregnant rats and rabbits during organogenesis at exposures up to 4.9 and 48.8 times the HDD, respectively [see Data]. Based on animal data, advise pregnant women of the potential risk to a fetus.

    The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

    Clinical Considerations

    Fetal/Neonatal Adverse Reactions

    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.
    Neonatal opioid withdrawal syndrome presents as irritability, hyperactivity and abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea and failure to gain weight. The 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. Observe newborns for symptoms of neonatal opioid withdrawal syndrome and manage accordingly [see Warnings and Precautions (5.4)].

    Labor or Delivery

    Opioids cross the 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 the neonate. Oxymorphone Hydrochloride Tablets is not recommended for use in pregnant women during or immediately prior to labor, when other analgesic techniques are more appropriate. Opioid analgesics, including Oxymorphone Hydrochloride Tablets, can prolong labor through actions which temporarily reduce the strength, duration, and frequency of uterine contractions. However, this effect is not consistent and may be offset by an increased rate of cervical dilation, which tends to shorten labor. Monitor neonates exposed to opioid analgesics during labor for signs of excess sedation and respiratory depression.

    Data

     Animal Data


    Pregnant rats were treated with oxymorphone hydrochloride from Gestation Day 6 to 17 via oral gavage doses of 5, 10, or 25 mg/kg/day (2.4, 4.9, or 12.2 times the HDD based on body surface   area, respectively). Reduced mean fetal weights were observed at 4.9 times the HDD. Maternal toxicity was noted in all treatment groups (reduced food consumption and body weights in all groups and mortality in the high dose group).

    Pregnant rabbits were treated with oxymorphone hydrochloride from Gestation Day 7 to 20 via oral gavage doses of 10, 25, or 50 mg/kg/day (9.8, 24.4, or 48.8 times the HDD based on body surface area, respectively). Decreased mean fetal weights were noted at 48.8 times the HDD. Maternal toxicity was noted in all treatment groups (reduced food consumption and body weights).
     
    Pregnant rats were treated with oxymorphone hydrochloride from Gestation Day 6 to Lactation Day 20 via oral gavage doses of 1, 5, 10, or 25 mg/kg/day (0.5, 2.4, 4.9, or 12.2 times the HDD based on body surface area, respectively). Increased neonatal death (postnatal day 0-1) was noted at 2.4 times the HDD. Decreased pup survival over the first week of life, reduced pup birth weight, and reduced postnatal weight gain were noted at 4.9 times the HDD. Maternal toxicity was noted in all treatment groups (reduced food consumption and body weights in all groups and mortality in the 10 and 25 mg/kg/day groups).

    In a published study, neural tube defects (exencephaly and cranioschisis) were noted following subcutaneous administration of 153 mg/kg oxymorphone hydrochloride (62.2 times the HDD) on Gestation Day 8 to pregnant hamsters. This dose also produced significant maternal toxicity (20% maternal deaths).

    8.2 Lactation

    Risk Summary
    There is no information regarding the presence of oxymorphone in human milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Oxymorphone Hydrochloride Tablets and any potential adverse effects on the breastfed child from Oxymorphone Hydrochloride Tablets or from the underlying maternal condition.

    Clinical Considerations
    Monitor infants exposed to Oxymorphone Hydrochloride Tablets through breast milk for excess sedation and respiratory depression. Withdrawal symptoms can occur in breast-fed infants when maternal administration of an opioid analgesic is stopped, or when breast-feeding is stopped.

    The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Oxymorphone Hydrochloride Tablets and any potential adverse effects on the breastfed infant from Oxymorphone Hydrochloride Tablets or from the underlying maternal condition.



    8.3 Females and Males of Reproductive Potential

    Infertility
    Chronic use of opioids may cause reduced fertility in females and males of reproductive potential. It is not known whether these effects on fertility are reversible [see Clinical Pharmacology (12.2), Nonclinical Toxicology (13.1)].


    8.4 Pediatric Use

    Safety and effectiveness for pediatric patients, 0 to 17 years, have not been established.

    An open-label study was conducted in 58 pediatric patients 12 years of age and older with postoperative pain using Oxymorphone Hydrochloride Tablets. Efficacy was not demonstrated in this population treated with doses expected to be comparable to effective starting doses in adults. In addition, pharmacokinetic results demonstrated that treatment with Oxymorphone Hydrochloride Tablets resulted in substantially higher systemic exposures to oxymorphone in 2 out of 24 patients.

    Oxymorphone Hydrochloride Tablets are not recommended for use in the pediatric population.


    8.5 Geriatric Use

    Oxymorphone Hydrochloride Tablets should be used with caution in elderly patients [see Clinical Pharmacology (12.3)].

    Of the total number of subjects in clinical studies of Oxymorphone Hydrochloride Tablets, 31% were 65 and over, while 7% were 75 and over. No overall differences in effectiveness were observed between these subjects and younger subjects. There were several adverse events that were more frequently observed in subjects 65 and over compared to younger subjects. These adverse events included dizziness, somnolence, confusion, and nausea. In general, dose selection for elderly patients should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.

    Respiratory depression is the chief risk for elderly patients treated with opioids, and has occurred after large initial doses were administered to patients who were not opioid-tolerant or when opioids were co- administered with other agents that depress respiration. Titrate the dosage of Oxymorphone Hydrochloride Tablets slowly in geriatric patients and monitor closely for signs of central nervous system and respiratory depression [see Warnings and Precautions (5.6)].

    Oxymorphone is known to be substantially excreted by the kidney and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because the elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.


    8.6 Hepatic Impairment

    In a study of extended-release oxymorphone tablets, patients with mild hepatic impairment were shown to have an increase in bioavailability compared to the subjects with normal hepatic function. Oxymorphone Hydrochloride Tablets should be used with caution in patients with mild impairment. These patients should be started with the lowest dose (5 mg) and titrated slowly while carefully monitoring for signs of respiratory and central nervous system depression. Oxymorphone Hydrochloride Tablets is contraindicated for patients with moderate and severe hepatic impairment [see Dosage and Administration (2.3), Contraindications (4), Warnings and Precautions (5.15), and Clinical Pharmacology (12.3)].

    8.7 Renal Impairment


    In a study of extended-release oxymorphone tablets, patients with moderate to severe renal impairment were shown to have an increase in bioavailability compared to the subjects with normal renal function [see Clinical Pharmacology (12.3)]. Such patients should be started be started with the lowest dose (5 mg) and titrated slowly while monitoring for signs of respiratory and central nervous system depression [see Dosage and Administration (2.4) Clinical Pharmacology (12.3)].


  • 9 DRUG ABUSE AND DEPENDENCE

    9.1 Controlled Substance


    Oxymorphone Hydrochloride Tablets contains oxymorphone, a Schedule II controlled substance

    9.2 Abuse

    Oxymorphone Hydrochloride Tablets contains oxymorphone, a substance with a high potential for abuse similar to other opioids including fentanyl, hydrocodone, hydromorphone, methadone, morphine, oxycodone and tapentadol. Oxymorphone Hydrochloride Tablets can be abused and is subject to misuse, addiction, and criminal diversion [see Warnings and Precautions (5.1)].

    All patients treated with opioids require careful monitoring for signs of abuse and addiction, because use of opioid analgesic products carries the risk of addiction even under appropriate medical use.

    Prescription drug abuse is the intentional non-therapeutic use of a prescription drug, even once, for its rewarding psychological or physiological effects.

    Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that develop after repeated substance use and includes: a strong desire to take the drug, difficulties in controlling its use, persisting in its use despite harmful consequences, a higher priority given to drug use than to other activities and obligations, increased tolerance, and sometimes a physical withdrawal.

    "Drug-seeking" behavior is very common in persons with substance use disorders. Drug-seeking tactics include emergency calls or visits near the end of office hours, refusal to undergo appropriate examination, testing, or referral, repeated "loss" of prescriptions, tampering with prescriptions, and reluctance to provide prior medical records or contact information for other treating healthcare provider(s). "Doctor shopping" (visiting multiple prescribers to obtain additional prescriptions) is common among drug abusers and people suffering from untreated addiction. Preoccupation with achieving adequate pain relief can be appropriate behavior in a patient with poor pain control.

    Abuse and addiction are separate and distinct from physical dependence and tolerance. Health care providers should be aware that addiction may not be accompanied by concurrent tolerance and symptoms of physical dependence in all addicts. In addition, abuse of opioids can occur in the absence of true addiction.

    Oxymorphone Hydrochloride Tablets, like other opioids, can be diverted for non-medical use into illicit channels of distribution. Careful record-keeping of prescribing information, including quantity, frequency, and renewal requests, as required by state and federal law, is strongly advised.

    Proper assessment of the patient, proper prescribing practices, periodic re-evaluation of therapy, and proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs.
     
    Risks Specific to Abuse of Oxymorphone Hydrochloride Tablets
    Oxymorphone Hydrochloride Tablets is for oral use only. Abuse of Oxymorphone Hydrochloride Tablets poses a risk of overdose and death. This risk is increased with concurrent abuse of Oxymorphone Hydrochloride Tablets with alcohol and other central nervous system depressants.

    Parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and HIV.


    9.3 Dependence

    Both tolerance and physical dependence can develop during chronic opioid therapy. Tolerance is the need for increasing doses of opioids to maintain a defined effect such as analgesia (in the absence of disease progression or other external factors). Tolerance may occur to both the desired and undesired effects of drugs, and may develop at different rates for different effects.

    Physical dependence results in withdrawal symptoms after abrupt discontinuation or a significant dosage reduction of a drug. Withdrawal also may be precipitated through the administration of drugs with opioid antagonist activity (e.g., naloxone, nalmefene), mixed agonist/antagonist analgesics (e.g., pentazocine, butorphanol, nalbuphine), or partial agonists (e.g., buprenorphine). Physical dependence may not occur to a clinically significant degree until after several days to weeks of continued opioid usage.

    Do not abruptly discontinue Oxymorphone Hydrochloride Tablets in a patient physically dependent on opioids. Rapid tapering of Oxymorphone Hydrochloride Tablets in a patient physically dependent on opioids may lead to serious withdrawal symptoms, uncontrolled pain, and suicide. Rapid discontinuation has also been associated with attempts to find other sources of opioid analgesics, which may be confused with drug-seeking for abuse.

    When discontinuing Oxymorphone Hydrochloride Tablets, gradually taper the dosage using a patient-specific plan that considers the following: the dose of Oxymorphone Hydrochloride Tablets the patient has been taking, the duration of treatment, and the physical and psychological attributes of the patient. To improve the likelihood of a successful taper and minimize withdrawal symptoms, it is important that the opioid tapering schedule is agreed upon by the patient. In patients taking opioids for a long duration at high doses, ensure that a multimodal approach to pain management, including mental health support (if needed), is in place prior to initiating an opioid analgesic taper [see Dosage and Administration (2.8), Warnings and Precautions (5.13)].

    Infants born to mothers physically dependent on opioids will also be physically dependent and may exhibit respiratory difficulties and withdrawal signs [see Warnings and Precautions (5.4), Use in Specific Populations (8.1)].


  • 10 OVERDOSAGE

    Clinical Presentation
    Acute overdose with Oxymorphone Hydrochloride Tablets can be manifested by respiratory depression, somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and, in some cases, pulmonary edema, bradycardia, hypotension, partial or complete airway obstruction, atypical snoring, and death. Marked mydriasis rather than miosis may be seen with hypoxia in overdose situations [see Clinical Pharmacology (12.2)].

    Treatment of Overdose
    In case of overdose, priorities are the reestablishment of a patent and protected airway and institution of assisted or controlled ventilation, if needed. Employ other supportive measures (including oxygen and vasopressors) in the management of circulatory shock and pulmonary edema as indicated. Cardiac arrest or arrhythmias will require advanced life-support techniques.

    The opioid antagonists, naloxone or nalmefene, are specific antidotes to respiratory depression resulting from opioid overdose. For clinically significant respiratory or circulatory depression secondary to oxymorphone overdose, administer an opioid antagonist. Opioid antagonists should not be administered in the absence of clinically significant respiratory or circulatory depression secondary to oxymorphone overdose.

    Because the duration of opioid reversal is expected to be less than the duration of action of oxymorphone in Oxymorphone Hydrochloride Tablets, carefully monitor the patient until spontaneous respiration is reliably reestablished. If the response to an opioid antagonist is suboptimal or only brief in nature, administer additional antagonist as directed by the products prescribing information.

    In an individual physically dependent on opioids, administration of the recommended usual dosage of the antagonist will precipitate an acute withdrawal syndrome. The severity of the withdrawal symptoms experienced will depend on the degree of physical dependence and the dose of the antagonist administered. If a decision is made to treat serious respiratory depression in the physically dependent patient, administration of the antagonist should be initiated with care and by titration with smaller than usual doses of the antagonist.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action


    Oxymorphone is a full opioid agonist and is relatively selective for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of oxymorphone is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with oxymorphone.

    Clinically, dosage is titrated to provide adequate analgesia and may be limited by adverse reactions, including respiratory and CNS depression.

    The precise mechanism of the analgesic action is unknown. However, specific CNS opioid receptors for endogenous compounds with opioid-like activity have been identified throughout the brain and spinal cord and are thought to play a role in the analgesic effects of this drug.

    12.2 Pharmacodynamics

    Effects on the Central Nervous System
    Oxymorphone produces respiratory depression by direct action on brain stem respiratory centers. The respiratory depression involves a reduction in the responsiveness of the brain stem respiratory centers to both increases in carbon dioxide tension and electrical stimulation.

    Oxymorphone causes miosis, even in total darkness. Pinpoint pupils are a sign of opioid overdose but are not pathognomonic (e.g., pontine lesions of hemorrhagic or ischemic origins may produce similar findings). Marked mydriasis rather than miosis may be seen due to hypoxia in overdose situations.

    Effects on the Gastrointestinal Tract and Other Smooth Muscle
    Oxymorphone causes a reduction in motility associated with an increase in smooth muscle tone in the antrum of the stomach and duodenum. Digestion of food in the small intestine is delayed and propulsive contractions are decreased. Propulsive peristaltic waves in the colon are decreased, while tone may be increased to the point of spasm, resulting in constipation. Other opioid-induced effects may include a reduction in biliary and pancreatic secretions, spasm of sphincter of Oddi, and transient elevations in serum amylase.

    Effects on the Cardiovascular System
    Oxymorphone produces peripheral vasodilation which may result in orthostatic hypotension or syncope. Manifestations of histamine release and/or peripheral vasodilation may include pruritus, flushing, red eyes and sweating and/or orthostatic hypotension.

    Effects on the Endocrine System
    Opioids inhibit the secretion of adrenocorticotropic hormone (ACTH), cortisol, and luteinizing hormone (LH) in humans [see Adverse Reactions (6.2)]. They also stimulate prolactin, growth hormone (GH) secretion, and pancreatic secretion of insulin and glucagon.

    Chronic use of opioids may influence the hypothalamic-pituitary-gonadal axis, leading to androgen deficiency that may manifest as low libido, impotence, erectile dysfunction, amenorrhea, or infertility. The causal role of opioids in the clinical syndrome of hypogonadism is unknown because the various medical, physical, lifestyle, and psychological stressors that may influence gonadal hormone levels have not been adequately controlled for in studies conducted to date [see Adverse Reactions (6.2)].

    Effects on the Immune System
    Opioids have been shown to have a variety of effects on components of the immune system in in vitro and animal models. The clinical significance of these findings is unknown. Overall, the effects of opioids appear to be modestly immunosuppressive.

    Concentration–Efficacy Relationships
    The minimum effective analgesic concentration varies widely among patients, especially among patients who have been previously treated with potent agonist opioids The minimum effective analgesic concentration of oxymorphone for any individual patient may increase over time due to an increase in pain, the development of a new pain syndrome and/or the development of analgesic tolerance [see Dosage and Administration (2.1, 2.2)].

    Concentration–Adverse Reaction Relationships
    There is a relationship between increasing oxymorphone plasma concentration and increasing frequency of dose-related opioid adverse reactions such as nausea, vomiting, CNS effects, and respiratory depression. In opioid-tolerant patients, the situation may be altered by the development of tolerance to opioid-related adverse reactions [see Dosage and Administration (2.1, 2.2, 2.6)].


    12.3 Pharmacokinetics

    Absorption
    The absolute oral bioavailability of oxymorphone is approximately 10%. Studies in healthy volunteers reveal predictable relationships between oxymorphone hydrochloride tablet dosage and plasma oxymorphone concentrations.

    Steady-state levels were achieved after three days of multiple dose administration. Under both single-dose and steady-state conditions, dose proportionality has been established for 5 mg, 10 mg and 20 mg doses of oxymorphone hydrochloride tablets, for both peak plasma levels (Cmax) and extent of absorption (AUC) (see Table 3).

    After oral dosing with 40 mg of Oxymorphone Hydrochloride Tablets in healthy volunteers under fasting conditions or with a high-fat meal, the Cmax and AUC were increased by approximately 38% in fed subjects relative to fasted subjects.

    As a result, Oxymorphone Hydrochloride Tablets should be dosed at least one hour prior to or two hours after eating [see Dosage and Administration (2.2)].
     Distribution
    Formal studies on the distribution of oxymorphone in various tissues have not been conducted. Oxymorphone is not extensively bound to human plasma proteins; binding is in the range of 10% to 12%.
     Elimination
    Oxymorphone Hydrochloride Tablets half-life ranges from approximately 9-11 hours after a single oral dose (5-40 mg).

    Metabolism
    Oxymorphone is highly metabolized, principally in the liver, and undergoes reduction or conjugation with glucuronic acid to form both active and inactive products. The two major metabolites of oxymorphone are oxymorphone-3-glucuronide and 6-OH-oxymorphone. The mean plasma AUC for oxymorphone-3- glucuronide is approximately 90-fold higher than the parent compound. The pharmacologic activity of the glucuronide metabolite has not been evaluated. 6-OH-oxymorphone has been shown in animal studies to have analgesic bioactivity. The mean plasma 6-OH-oxymorphone AUC is approximately 70% of the oxymorphone AUC following single oral doses but is essentially equivalent to the parent compound at steady-state.

    Excretion
    Because oxymorphone is extensively metabolized, <1% of the administered dose is excreted unchanged in the urine. On average, 33% to 38% of the administered dose is excreted in the urine as oxymorphone-3-glucuronide and 0.25% to 0.62% is excreted as 6-OH-oxymorphone in subjects with normal hepatic and renal function. In animals given radiolabeled oxymorphone, approximately 90% of the administered radioactivity was recovered within 5 days of dosing. The majority of oxymorphone-derived radioactivity was found in the urine and feces.

    Specific Populations

    Age: Geriatric Population
    The plasma levels of oxymorphone administered as an extended-release tablet were about 40% higher in elderly (≥65 years of age) than in younger subjects [see Use in Specific Populations (8.5)].

    Sex:
    The effect of sex on the pharmacokinetics of Oxymorphone Hydrochloride Tablets have not been studied. In a study with an extended-release formulation of oxymorphone, there was a consistent tendency for female subjects to have slightly higher AUCss and Cmax values than male subjects. However, sex differences were not observed when AUCss and Cmax were adjusted by body weight.
     

    Hepatic Impairment
    The liver plays an important role in the pre-systemic clearance of orally administered oxymorphone. Accordingly, the bioavailability of orally administered oxymorphone may be markedly increased in patients with moderate to severe liver disease. The effect of hepatic impairment on the pharmacokinetics of Oxymorphone Hydrochloride Tablets have not been studied. However, in a study with an extended-release formulation of oxymorphone, the disposition of oxymorphone was compared in 6 patients with mild, 5 patients with moderate, and one patient with severe hepatic impairment, and 12 subjects with normal hepatic function. The bioavailability of oxymorphone was increased by 1.6-fold in patients with mild hepatic impairment and by 3.7-fold in patients with moderate hepatic impairment. In one patient with severe hepatic impairment, the bioavailability was increased by 12.2-fold. The half-life of oxymorphone was not significantly affected by hepatic impairment.

    Renal Impairment
    The effect of renal impairment on the pharmacokinetics of Oxymorphone Hydrochloride Tablets have not been studied. However, in a study with an extended-release formulation of oxymorphone, an increase of 26%, 57%, and 65% in oxymorphone bioavailability was observed in mild (creatinine clearance 51-80 mL/min; n=8), moderate (creatinine clearance 30-50 mL/min; n=8), and severe (creatinine clearance <30 mL/min; n=8) patients, respectively, compared to healthy controls.

    Drug Interactions Studies
    In vitro studies revealed little to no biotransformation of oxymorphone to 6-OH-oxymorphone by any of the major cytochrome P450 (CYP P450) isoforms at therapeutically relevant oxymorphone plasma concentrations.
    No inhibition of any of the major CYP P450 isoforms was observed when oxymorphone was incubated with human liver microsomes at concentrations of ≤50 j.tM. An inhibition of CYP 3A4 activity occurred at oxymorphone concentrations ≥150 j.tM. Therefore, it is not expected that oxymorphone, or its metabolites will act as inhibitors of any of the major CYP P450 enzymes in vivo.
    Increases in the activity of the CYP 2C9 and CYP 3A4 isoforms occurred when oxymorphone was incubated with human hepatocytes. However, clinical drug interaction studies with Oxymorphone Hydrochloride Tablets ER showed no induction of CYP450 3A4 or 2C9 enzyme activity, indicating that no dose adjustment for CYP 3A4-or 2C9-mediated drug-drug interactions is required.

    Alcohol Interaction
    The effect of co-ingestion of alcohol with Oxymorphone Hydrochloride Tablets have not been evaluated. However, an in vivo study was performed to evaluate the effect of alcohol (40%, 20%, 4% and 0%) on the bioavailability of a single dose of 40 mg of extended-release oxymorphone tablets in healthy, fasted volunteers. Following concomitant administration of 240 mL of 40% ethanol the Cmax increased on average by 70% and up to 270% in individual subjects. Following the concomitant administration of 240 mL of 20% ethanol, the Cmax increased on average by 31% and up to 260% in individual subjects. In some individuals there was also a decrease in oxymorphone peak plasma concentrations. No effect on the release of oxymorphone from the extended-release tablet was noted in an in vitro alcohol interaction study. The mechanism of the in vivo interaction is unknown. Therefore, avoid co-administration of oxymorphone and ethanol.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis & Mutagenesis & Impairment Of Fertility




    Carcinogenesis
    No evidence of carcinogenic potential was observed in long-term animal studies in mice and rats. Oxymorphone hydrochloride was administered to Sprague Dawley rats (2.5, 5, and 10 mg/kg/day in males and 5, 10, and 25 mg/kg/day in females) for 2 years by oral gavage. Systemic drug exposure (AUC) at the highest doses tested in male and female rats was 4.8 times and 21.2 times the human exposure at a dose of 20 mg/day, respectively. Oxymorphone hydrochloride was administered to male and female CD-1 mice (10, 25, 75 and 150 mg/kg/day) for 2 years by oral gavage. Systemic drug exposure (AUC) at 150 mg/kg/day in male and female mice was 205 times and 243 times the human exposure at a dose of 20 mg/day, respectively.

    Mutagenesis
    Oxymorphone hydrochloride was not mutagenic when tested in the in vitro bacterial reverse mutation assay (Ames test), or in an in vitro mammalian cell chromosome aberration assay performed with human peripheral blood lymphocytes. Oxymorphone hydrochloride tested positive in both the rat and mouse in vivo micronucleus assays. An increase in micronucleated polychromatic erythrocytes occurred in mice given doses of ≥250 mg/kg and in rats given doses of 20 and 40 mg/kg. A subsequent study demonstrated that oxymorphone hydrochloride was not aneugenic in mice following administration of up to 500 mg/kg.

    Additional studies indicate that the increased incidence of micronucleated polychromatic erythrocytes in rats may be secondary to increased body temperature following oxymorphone administration. Doses associated with increased micronucleated polychromatic erythrocytes also produce a marked, rapid increase in body temperature. Pretreatment of animals with sodium salicylate minimized the increase in body temperature and prevented the increase in micronucleated polychromatic erythrocytes after administration of 40 mg/kg oxymorphone.

    Impairment of fertility
    Female rats were treated with oxymorphone hydrochloride beginning 14 days prior to mating through Gestation Day 7 via oral gavage doses of 5, 10, or 25 mg/kg/day (2.4, 4.9, or 12.2 times the human daily dose of 20 mg/day based on body surface area, respectively). Male rats were treated via oral gavage with the same oxymorphone hydrochloride doses beginning 28 days prior to and throughout mating. In female rats, an increase in the length of the estrus cycle and decrease in the mean number of viable embryos, implantation sites and corpora lutea were observed at 4.9 times the human dose of 20 mg/day. No adverse effects of oxymorphone on male reproductive function or sperm parameters were observed.


  • 14 CLINICAL STUDIES


    The analgesic efficacy of oxymorphone hydrochloride tablets has been evaluated in acute pain following orthopedic and abdominal surgeries.

    14.1 Orthopedic Surgery


    Two double-blind, placebo-controlled, dose-ranging studies in patients with acute moderate to severe pain following orthopedic surgery evaluated the doses of oxymorphone hydrochloride tablets 10 mg and 20 mg, and 30 mg was included in one study. Both studies demonstrated that oxymorphone hydrochloride tablets 20 mg provided greater analgesia as measured by total pain relief based on a weighted analysis over 8 hours using a 0 to 4 categorical, compared to placebo. Oxymorphone hydrochloride tablets 10 mg provided greater analgesia as compared to placebo in one of the two studies. There was no evidence of superiority of the 30 mg dose over the 20 mg dose. However, there was a high rate of naloxone use in patients receiving the oxymorphone hydrochloride tablets 30 mg dose in the post-operative period [see Dosage and Administration (2.2)].

    14.2 Abdominal Surgery


    In a randomized, double-blind, placebo-controlled, multiple-dose study, the efficacy of oxymorphone hydrochloride tablets 10 mg and 20 mg was assessed in patients with moderate to severe acute pain following abdominal surgery. In this study, patients were dosed every 4 to 6 hours over a 48-hour treatment period. Oxymorphone hydrochloride tablets 10 and 20 mg provided greater analgesia, as measured by the mean average pain intensity on a 0 to 100 mm visual analog scale, over 48 hours, compared to placebo [see Dosage and Administration (2.2)].
