  • BOXED WARNING(What is this?)

    WARNING: ADDICTION, ABUSE, AND MISUSE; LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL EXPOSURE; NEONATAL OPIOID WITHDRAWAL SYNDROME; and HEPATOTOXICITY

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

    Life-threatening Respiratory Depression
    Serious, life-threatening, or fatal respiratory depression may occur with use of XARTEMIS XR. Monitor for respiratory depression, especially during initiation of XARTEMIS XR or following a dose increase. Instruct patients to swallow XARTEMIS XR tablets whole; crushing, chewing, or dissolving XARTEMIS XR can cause rapid release and absorption of a potentially fatal dose of oxycodone [see Warnings and Precautions (5.2)].

    Accidental Exposure
    Accidental ingestion of XARTEMIS XR, especially in children, can result in a fatal overdose of oxycodone [see Warnings and Precautions (5.2)].

    Neonatal Opioid Withdrawal Syndrome
    Prolonged use of XARTEMIS XR during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized 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 (5.3)].

    Hepatotoxicity
    XARTEMIS XR contains acetaminophen. Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death. Most of the cases of liver injury are associated with the use of acetaminophen at doses that exceed the maximum daily limit, and often involve more than one acetaminophen-containing product [see Warnings and Precautions (5.7, 5.11)].

(5.7, 5.11)

    INDICATIONS AND USAGE

    XARTEMIS XR (oxycodone hydrochloride and acetaminophen) Extended-Release Tablets is a combination of oxycodone, an opioid agonist, and acetaminophen, and is indicated for the management of acute pain severe enough to require opioid treatment and for which alternative treatment options are inadequate.

    Limitations of Use:
    Because of the risks of addiction, abuse, misuse, overdose, and death with opioids, even at recommended doses, reserve XARTEMIS XR for use in patients for whom alternative treatment options (e.g., non-opioid analgesics) are ineffective, not tolerated, or would be otherwise inadequate. (1)

    DOSAGE AND ADMINISTRATION

    • The recommended dose of XARTEMIS XR is 2 tablets every 12 hours without regard to food. (2)
    • XARTEMIS XR tablets should be swallowed whole. Do not break, chew, crush, cut, dissolve or split, the tablets. Swallow with enough water to ensure complete swallowing immediately after placing in mouth. (2)

    DOSAGE FORMS AND STRENGTHS

    • Extended-release tablets (oxycodone hydrochloride/ acetaminophen): 7.5 mg/325 mg (3)

    CONTRAINDICATIONS

    • Patients who have known hypersensitivity to oxycodone, acetaminophen or any other components of the product. (4)
    • Patients who have significant respiratory depression. (4)
    • Patients who have acute or severe bronchial asthma or hypercarbia. (4)
    • Patients who have suspected or known paralytic ileus. (4)

    WARNINGS AND PRECAUTIONS

    • XARTEMIS XR is not interchangeable with other oxycodone/ acetaminophen products because of differing pharmacokinetic profiles that affect the frequency of administration. (5)
    • Controlled substance: XARTEMIS XR is a Schedule II controlled substance with an abuse liability similar to other opioids. (5.1)
    • Accidental exposure, especially in children, can result in fatal overdose of oxycodone. (5.2)
    • Interactions with CNS depressants: Concomitant use may cause profound sedation, respiratory depression, and death. If coadministration is required, consider dose reduction of one or both drugs. (5.4)
    • Use with caution in patients who are receiving other CNS depressants. (5.4, 7.1)
    • Elderly, cachectic, debilitated patients, and those with chronic pulmonary disease: Monitor closely because of increased risk for life-threatening respiratory depression. (5.5, 5.6)
    • Use caution when administering in patients with hepatic impairment. (5.7)
    • May cause serious skin reactions. Discontinue use if reaction occurs. (5.8)
    • May worsen increased intracranial pressure and obscure its signs, such as level of consciousness or pupillary signs. (5.9)
    • May cause hypotension. Use with caution in patients at increased risk of hypotension and in patients in circulatory shock. (5.10)
    • Due to the potential for acetaminophen hepatotoxicity at doses higher than 4000 mg/day, XARTEMIS XR should not be used with other acetaminophen-containing products. (5.11)
    • Discontinue XARTEMIS XR immediately if symptoms associated with allergy or hypersensitivity occur. Do not use in patients with acetaminophen allergy. (5.12)
    • Use with caution in patients with biliary tract disease, including acute pancreatitis. (5.14)
    • Concomitant use of CYP3A4 inhibitors may increase opioid effects. (5.15)
    • May impair the mental and physical abilities needed to perform potentially hazardous activities such as driving a car or operating machinery. (5.16)

    ADVERSE REACTIONS

    The most common adverse events with XARTEMIS XR are nausea, dizziness, headache, vomiting, constipation and somnolence. (6.1)

    To report SUSPECTED ADVERSE REACTIONS, contact Mallinckrodt at 1-800-778-7898 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

    DRUG INTERACTIONS

    • Concurrent use of other CNS depressants may cause respiratory depression, hypotension, and profound sedation or coma. (7.1)
    • XARTEMIS XR may enhance the neuromuscular blocking action of skeletal muscle relaxants and produce an increased degree of respiratory depression. (7.2)
    • Monoamine oxidase inhibitors may intensify the effects of opioids causing anxiety, confusion and significant depression of respiration or coma. (7.3)
    • The CYP3A4 isoenzyme plays a major role in the metabolism of XARTEMIS XR; drugs that inhibit CYP3A4 activity may cause decreased clearance of oxycodone which could lead to an increase in oxycodone plasma concentrations. (7.4)
    • Mixed agonist/antagonist analgesics may reduce the analgesic effect of oxycodone and may precipitate withdrawal symptoms in these patients. (7.5)
    • Anticholinergics may increase risk for urinary retention and severe constipation. (7.6)

    USE IN SPECIFIC POPULATIONS

    • Pregnancy: Based on animal data, may cause fetal harm. (8.1)
    • Labor and Delivery: Not recommended for use in women immediately prior to and during labor and delivery. (8.2)
    • Nursing Mothers: Discontinue nursing or discontinue drug. (8.3)
    • Geriatric use: Dose with caution as clearance of oxycodone may be slightly reduced in this population. (8.5)
    • Hepatic impairment: Dose initiation should follow a conservative approach. (8.6)
    • Renal impairment: Dose initiation should follow a conservative approach. (8.7)

  • 1 INDICATIONS AND USAGE

    XARTEMIS XR is indicated for the management of acute pain severe enough to require opioid treatment and for which alternative treatment options are inadequate.

    Limitations of Use
    Because of the risks of addiction, abuse, misuse, overdose, and death with opioids, even at recommended doses, reserve XARTEMIS XR for use in patients for whom alternative treatment options (e.g., non-opioid analgesics) are ineffective, not tolerated, or would be otherwise inadequate.

    Close
  • 2 DOSAGE AND ADMINISTRATION

    XARTEMIS XR is not interchangeable with other oxycodone/acetaminophen products because of differing pharmacokinetic profiles that affect the frequency of administration.

    2.1       Initial Dosage

    Initiate the dosing regimen for each patient individually, taking into account the patient's 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 with XARTEMIS XR [see Warnings and Precautions (5.2)].

    Use of XARTEMIS XR as the First Opioid Analgesic
    The recommended dose of XARTEMIS XR is 2 tablets every 12 hours administered with or without food. The second dose of 2 tablets may be administered as early as 8 hours after the initial dose if patients require analgesia at that time. Subsequent doses are to be administered 2 tablets every 12 hours.

    XARTEMIS XR is given orally. XARTEMIS XR tablets should be swallowed whole, one tablet at a time, with enough water to ensure complete swallowing immediately after placing in mouth [see Patient Counseling Information (17)]. Do not break, chew, crush, cut, dissolve or split the tablets. Breaking, chewing, crushing, cutting, dissolving or splitting XARTEMIS XR tablets will result in uncontrolled delivery of oxycodone and can lead to overdose or death [see Warnings and Precautions (5.1)].

    The total daily dose of acetaminophen from all drug products should not exceed 4000 milligrams.

    2.2       Hepatic Impairment

    In patients with hepatic impairment start with one tablet and adjust dosage as needed. Monitor closely for respiratory depression [see Clinical Pharmacology (12.3)].

    2.3       Renal Impairment

    In patients with renal impairment start with one tablet and adjust dosage as needed. Monitor closely for respiratory depression [see Clinical Pharmacology (12.3)].

    2.4       Cessation of Therapy

    When a patient who has been taking XARTEMIS XR regularly and may be physically dependent no longer requires therapy with XARTEMIS XR use a gradual downward titration of the dose of 50% every 2 to 4 days to prevent signs and symptoms of withdrawal. Do not stop XARTEMIS XR abruptly in patients who may be physically dependent.

    Close
  • 3 DOSAGE FORMS AND STRENGTHS

    XARTEMIS XR is an extended-release tablet for oral administration. Each tablet contains 7.5 mg oxycodone hydrochloride and 325 mg acetaminophen.

    Close
  • 4 CONTRAINDICATIONS

    XARTEMIS XR tablets are contraindicated in patients with

    • Known hypersensitivity to oxycodone, acetaminophen, or any other component of this product [see Warnings and Precautions (5.12)].
    • Significant respiratory depression
    • Acute or severe bronchial asthma or hypercarbia
    • Known or suspected paralytic ileus
    Close
  • 5 WARNINGS AND PRECAUTIONS

    XARTEMIS XR is not interchangeable with other oxycodone/acetaminophen products because of differing pharmacokinetic profiles that affect the frequency of administration.

    5.1       Addiction, Abuse, and Misuse

    XARTEMIS XR contains oxycodone, a Schedule II controlled substance. As an opioid, XARTEMIS XR 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 XARTEMIS XR and in those who obtain the drug illicitly. Addiction can occur at recommended doses and if the drug is misused or abused.

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

    Abuse or misuse of XARTEMIS XR by crushing, chewing, snorting, or injecting the dissolved product will result in the uncontrolled delivery of the oxycodone and can result in overdose and death [see Overdosage (10)].

    5.2       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 from opioid use, 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 XARTEMIS XR, the risk is greatest during the initiation of therapy or following a dose increase. Closely monitor patients for respiratory depression when initiating therapy with XARTEMIS XR and following dose increases.

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

    Accidental consumption of XARTEMIS XR, especially by children, can result in respiratory depression and death due to an overdose of oxycodone.

    5.3       Neonatal Opioid Withdrawal Syndrome

    Prolonged use of XARTEMIS XR during pregnancy can result in withdrawal signs in the neonate. Neonatal opioid withdrawal syndrome, unlike opioid withdrawal syndrome in adults, may be life-threatening if not recognized 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.

    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.

    5.4       Interactions with Central Nervous System Depressants

    Hypotension, profound sedation, coma, respiratory depression, and death may result if XARTEMIS XR is used concomitantly with alcohol or other central nervous system (CNS) depressants (e.g., sedatives, anxiolytics, hypnotics, neuroleptics, other opioids).

    When considering the use of XARTEMIS XR in a patient taking a CNS depressant, assess the duration use of the CNS depressant and the patient’s response, including the degree of tolerance that has developed to CNS depression. Additionally, evaluate the patient’s use of alcohol or illicit drugs that cause CNS depression. If the decision to begin XARTEMIS XR is made, start with XARTEMIS XR 1 tablet every 12 hours, monitor patients for signs of sedation and respiratory depression, and consider using a lower dose of the concomitant CNS depressant [see Drug Interactions (7.1)].

    5.5       Elderly, Cachectic, and Debilitated Patients

    Life-threatening respiratory depression is more likely to occur in elderly, cachectic, or debilitated patients as they may have altered pharmacokinetics or altered clearance compared to younger, healthier patients. Monitor such patients closely, particularly when initiating and titrating XARTEMIS XR and when XARTEMIS XR is given concomitantly with other drugs that depress respiration [see Warnings and Precautions (5.2)].

    5.6       Use in Patients with Chronic Pulmonary Disease

    Monitor patients with significant chronic obstructive pulmonary disease or cor pulmonale, and patients having a substantially decreased respiratory reserve, hypoxia, hypercapnia, or preexisting respiratory depression for respiratory depression, particularly when initiating therapy and titrating with XARTEMIS XR, as in these patients, even usual therapeutic doses of XARTEMIS XR may decrease respiratory drive to the point of apnea [see Warnings and Precautions (5.2)]. Consider the use of alternative non-opioid analgesics in these patients if possible.

    5.7       Hepatotoxicity

    XARTEMIS XR contains oxycodone and acetaminophen. Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death. Most of the cases of liver injury are associated with the use of acetaminophen at doses that exceed 4000 milligrams per day, and often involve more than one acetaminophen-containing product. The excessive intake of acetaminophen may be intentional to cause self-harm or unintentional as patients attempt to obtain more pain relief or unknowingly take other acetaminophen-containing products. The typical daily acetaminophen contribution from XARTEMIS XR is 1300 mg.

    The risk of acute liver failure is higher in individuals with underlying liver disease and in individuals who ingest alcohol while taking acetaminophen.

    Instruct patients to look for acetaminophen or APAP on package labels and not to use more than one product that contains acetaminophen. Instruct patients to seek medical attention immediately upon ingestion of more than 4000 milligrams of acetaminophen per day, even if they feel well.

    5.8       Serious Skin Reactions

    Rarely, acetaminophen may cause serious skin reactions such as acute generalized exanthematous pustulosis (AGEP), Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. Inform patients about the signs of serious skin reactions, and use of the drug should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity.

    5.9       Head Injury and Increased Intracranial Pressure

    The respiratory depressant effects of narcotics and their capacity to elevate cerebrospinal fluid pressure may be markedly exaggerated in the presence of head injury, other intracranial lesions, or a pre-existing increase in intracranial pressure. Furthermore, narcotics produce adverse reactions which may obscure the clinical course of patients with head injuries.

    5.10    Hypotensive Effect

    Oxycodone may cause severe hypotension particularly in individuals whose ability to maintain blood pressure has been compromised by a depleted blood volume, or after concurrent administration with drugs which compromise vasomotor tone such as phenothiazines. Administer XARTEMIS XR with caution to patients in circulatory shock, since vasodilation produced by the drug may further reduce cardiac output and blood pressure. XARTEMIS XR may produce orthostatic hypotension in ambulatory patients [see Drug Interactions (7.1)].

    5.11     Use With Other Acetaminophen-containing Products

    The typical daily acetaminophen-contribution from XARTEMIS XR is 1300 mg. Due to the potential for acetaminophen hepatotoxicity at doses higher than 4000 milligrams/day, XARTEMIS XR should not be used concomitantly with other acetaminophen-containing products.

    5.12    Hypersensitivity/Anaphylaxis

    There have been post-marketing reports of hypersensitivity and anaphylaxis associated with use of acetaminophen. Clinical signs included swelling of the face, mouth, and throat, respiratory distress, urticaria, rash, pruritus, and vomiting. There were infrequent reports of life-threatening anaphylaxis requiring emergency medical attention. Instruct patients to discontinue XARTEMIS XR immediately and seek medical care if they experience these symptoms. Do not prescribe XARTEMIS XR for patients with acetaminophen allergy.

    5.13    Difficulty Swallowing

    Due to characteristics of the formulation that cause the tablets to swell and become sticky when wet, consider use of an alternative analgesic in patients who have difficulty swallowing and patients at risk for underlying GI disorders resulting in a small gastrointestinal lumen. Instruct patients not to pre-soak, lick or otherwise wet XARTEMIS XR tablets prior to placing in the mouth, and to take one tablet at a time with enough water to ensure complete swallowing immediately after placing in mouth.

    5.14    Gastrointestinal Effects

    XARTEMIS XR is contraindicated in patients with known or suspected paralytic ileus. Opioids diminish propulsive peristaltic waves in the gastrointestinal tract and decrease bowel motility. Monitor for decreased bowel motility in post-operative patients receiving opioids. The administration of XARTEMIS XR may obscure the diagnosis or clinical course in patients with acute abdominal conditions. Oxycodone may cause spasm of the Sphincter of Oddi. Monitor patients with biliary tract disease, including acute pancreatitis.

    5.15    Cytochrome P450 3A4 Inhibitors and Inducers

    Since the CYP3A4 isoenzyme plays a major role in the metabolism of XARTEMIS XR, drugs that alter CYP3A4 activity may cause changes in clearance of oxycodone which could lead to changes in oxycodone plasma concentrations.

    Inhibition of CYP3A4 activity by its inhibitors, such as macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g., ketoconazole), and protease inhibitors (e.g., ritonavir), may increase plasma concentrations of oxycodone and prolong opioid effects. These effects could be more pronounced with concomitant use of CYP 2D6 and 3A4 inhibitors.

    Cytochrome P450 inducers, such as rifampin, carbamazepine, and phenytoin, may induce the metabolism of oxycodone and, therefore, may cause increased clearance of the drug which could lead to a decrease in oxycodone plasma concentrations, resulting in a potential lack of efficacy.

    If co-administration is necessary, caution is advised when initiating XARTEMIS XR treatment in patients currently taking, or discontinuing CYP3A4 inhibitors or inducers. Evaluate these patients at frequent intervals and consider dose adjustments until stable drug effects are achieved [see Drug Interactions (7.4)].

    5.16    Driving and Operating Machinery

    XARTEMIS XR may impair the mental and/or physical abilities required for the performance of potentially hazardous tasks such as driving a car or operating machinery. The patient using this drug should be cautioned accordingly.

  • 6 ADVERSE REACTIONS

    The following treatment-emergent adverse reactions are discussed in more detail in other sections of the labeling:

    • Respiratory Depression [see Contraindications (4), Warnings and Precautions (5.2), and Overdosage (10)]
    • Hepatotoxicity [see Warnings and Precautions (5.7)]
    • Use With Other Acetaminophen-containing Products [see Warnings and Precautions (5.11)]
    • Interactions with Other CNS Depressants [see Warnings and Precautions (5.4)]

    6.1       Clinical Studies Experience

    Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in clinical practice.

    In safety data from two Phase 3 (one placebo-controlled, one open-label) trials where multiple doses of XARTEMIS XR were administered for up to 42 days, the most common adverse reactions (reported by ≥10% in any XARTEMIS XR dose group) were: nausea, dizziness and vomiting. The most common reasons for discontinuation due to AEs in these 2 studies (reported by ≥1% in any XARTEMIS XR dose group) were vomiting (4.8%) and nausea (4.1%); there were no reports of these adverse reactions in the placebo-treated patients.

    A total of 1028 subjects in 14 clinical studies were treated with XARTEMIS XR during the clinical development program, including 892 subjects treated with 15 mg oxycodone and 650 mg acetaminophen. This dosage regimen of XARTEMIS XR was administered to 607 patients in two Phase 3 studies (one placebo-controlled and one open-label).

    In a placebo-controlled post-bunionectomy acute pain trial, 329 patients were dosed with 15 mg oxycodone and 650 mg acetaminophen XARTEMIS XR or placebo orally every 12 hours, for approximately 48 hours (blinded period) [see Clinical Studies (14)]. Table 1 lists the adverse reactions reported by ≥1% of XARTEMIS XR-treated patients and more frequently in XARTEMIS XR-treated patients compared with placebo.

  • 7 DRUG INTERACTIONS

    7.1   CNS Depressants

    The concomitant use of XARTEMIS XR with other CNS depressants including sedatives, hypnotics, tranquilizers, general anesthetics, phenothiazines, other opioids, and alcohol can increase the risk of respiratory depression, profound sedation, coma and death. Monitor patients receiving CNS depressants and XARTEMIS XR for signs of respiratory depression, sedation and hypotension.

    When combined therapy with any of the above medications is considered, the dose of one or both agents should be reduced [see Dosage and Administration (2.2) and Warnings and Precautions (5.4)].

    7.2    Neuromuscular Blocking Agents

    Oxycodone, as well as other opioid analgesics, may enhance the neuromuscular blocking action of skeletal muscle relaxants and produce an increased degree of respiratory depression.

    7.3       Monoamine Oxidase Inhibitors

    Monoamine Oxidase Inhibitors (MAOIs) have been reported to intensify the effects of at least one opioid drug causing anxiety, confusion, and significant depression of respiration or coma. The use of XARTEMIS XR is not recommended for patients taking MAOIs or within 14 days of stopping such treatment.

    7.4       Agents Affecting Cytochrome P450 Enzymes

    CYP3A4 Inhibitors
    Because the CYP3A4 isoenzyme plays a major role in the metabolism of oxycodone, drugs that inhibit CYP3A4 activity may cause decreased clearance of oxycodone which could lead to an increase in oxycodone plasma concentrations and result in increased or prolonged opioid effects. These effects could be more pronounced with concomitant use of CYP2D6 and 3A4 inhibitors. If co-administration with XARTEMIS XR is necessary, monitor patients for respiratory depression and sedation at frequent intervals and consider dose adjustments until stable drug effects are achieved [see Clinical Pharmacology (12.3)].

    CYP3A4 Inducers
    CYP450 3A4 inducers may induce the metabolism of oxycodone and, therefore, may cause increased clearance of the drug which could lead to a decrease in oxycodone plasma concentrations, lack of efficacy or, possibly, development of a withdrawal syndrome in a patient who had developed physical dependence to oxycodone. If co-administration with XARTEMIS XR is necessary, monitor for signs of opioid withdrawal and consider dose adjustments until stable drug effects are achieved [see Clinical Pharmacology (12.3)].

    CYP2D6 Inhibitors
    Oxycodone is metabolized in part to oxymorphone via the Cytochrome P450 isoenzyme CYP2D6. While this pathway may be blocked by a variety of drugs (e.g., certain cardiovascular drugs, including amiodarone and quinidine, and antidepressants), such blockade has not yet been shown to be of clinical significance with this agent. However, clinicians should be aware of this possible interaction [see Clinical Pharmacology (12.3)].

    7.5       Mixed Agonist/Antagonist Opioid Analgesics

    Agonist/antagonist analgesics (i.e., pentazocine, nalbuphine, butorphanol, and buprenorphine) should be administered with caution to patients who have received or are receiving a course of therapy with an opioid agonist analgesic such as XARTEMIS XR. In this situation, mixed agonist/antagonist analgesics may reduce the analgesic effect of XARTEMIS XR and/or may precipitate withdrawal symptoms in these patients.

    7.6       Anticholinergics

    Anticholinergics or other medications with anticholinergic activity when used concurrently with opioid analgesics may result in increased risk of urinary retention and/or severe constipation, which may lead to paralytic ileus.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Pregnancy Category C
    Risk Summary
    There are no adequate and well-controlled studies of XARTEMIS XR tablets or oxycodone/acetaminophen in pregnant women. Epidemiological data on oral acetaminophen use in pregnant women show no increased risk of major congenital malformations. The incidence of malformations in human pregnancies has not been established for oxycodone as the data are limited. All pregnancies, regardless of drug exposure, have a background risk of 2 to 4% for major birth defects, and 15 to 20% for pregnancy loss.

    No animal reproductive or developmental studies were conducted with the combination of oxycodone and acetaminophen, the components of XARTEMIS XR. The following data are based on findings from studies performed with the individual components. Reproductive and developmental studies in rats and mice from the published literature identified adverse events at clinically relevant doses with acetaminophen. Treatment of pregnant rats with doses of acetaminophen approximately equal to the maximum human daily dose (MHDD) showed evidence of fetotoxicity and increases in bone variations in the fetuses. In another study, necrosis was observed in the liver and kidney of both pregnant rats and fetuses at doses approximately equal to the MHDD. In mice treated with acetaminophen at doses within the clinical dosing range, a reduction in number of litters of the parental mating pair was observed as well as retarded growth and abnormal sperm in their offspring and reduced birth weight in the next generation. Reproductive studies in rats and rabbits with doses of oxycodone greater than clinical doses did not show any teratogenic or embryo-fetal toxic effects. XARTEMIS XR should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

    Clinical Considerations
    Fetal/Neonatal Adverse Reactions
    Prolonged maternal 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. Observe newborns for symptoms of neonatal opioid withdrawal syndrome, such as poor feeding, diarrhea, irritability, tremor, rigidity, and seizures, and manage accordingly [see Warnings and Precautions (5.3)].

    8.2 Labor and Delivery

    Opioids cross the placenta and may produce respiratory depression and psycho-physiologic effects in neonates. XARTEMIS XR is not recommended for use in women during or immediately prior to labor. Neonates, whose mothers received opioid analgesics during labor, must be observed closely for signs of respiratory depression. An opioid antagonist such as naloxone, must be available for reversal of opioid-induced respiratory depression in the neonate.

    Data
    Human Data
    Two large population based studies have evaluated the safety of acetaminophen in pregnant women during the first trimester; neither study showed an increased risk of congenital malformations. Available published data on oxycodone exposure during pregnancy and risk for malformations are limited and do not allow conclusions regarding a possible association.

    Animal Data
    No reproductive or developmental studies were conducted with the combination of oxycodone and acetaminophen, the components of XARTEMIS XR. The following data are based on findings from studies performed with the individual components.

    Studies in pregnant rats that received oral acetaminophen during organogenesis at doses up to 0.85 times the maximum human daily dose (MHDD = 4 grams/day, based on a body surface area comparison) showed evidence of fetotoxicity (reduced fetal weight and length) and a dose-related increase in bone variations (reduced ossification and rudimentary rib changes). Offspring had no evidence of external, visceral, or skeletal malformations. When pregnant rats received oral acetaminophen throughout gestation at doses of 1.2-times the MHDD (based on a body surface area comparison), areas of necrosis occurred in both the liver and kidney of pregnant rats and fetuses. These effects did not occur in animals that received oral acetaminophen at doses 0.3-times the MHDD, based on a body surface area comparison. In a continuous breeding study, pregnant mice received 0.25, 0.5, or 1.0% acetaminophen via the diet (357, 715, or 1430 mg/kg/day). These doses are approximately 0.43, 0.87, and 1.7 times the MHDD, respectively, based on a body surface area comparison. A dose-related reduction in body weights of fourth and fifth litter offspring of the treated mating pair occurred during lactation and post-weaning at all doses. Animals in the high dose group had a reduced number of litters per mating pair, male offspring with an increased percentage of abnormal sperm, and reduced birth weights in the next generation pups. Reproduction studies in Sprague-Dawley rats and New Zealand rabbits revealed that when oxycodone was administered orally at doses up to 16 mg/kg (approximately 2 times the daily oral dose of 90 mg for adults based on a body surface area comparison) and 25 mg/kg (approximately 5 times the daily oral dose of 90 mg based on body surface area comparison), it was non teratogenic or embryo-fetal toxic.

    8.3 Nursing Mothers

    Oxycodone is present in human milk and may result in accumulation and toxicities such as sedation and respiratory depression in some infants. Acetaminophen is present in human milk in small quantities. Based on data from more than 15 nursing mothers, the calculated infant daily dose of acetaminophen is approximately 1 to 2% of the maternal dose. There is one well-documented report of a rash in a breast-fed infant that resolved when the mother stopped acetaminophen use and recurred when she resumed acetaminophen use. Because of the potential for serious adverse reactions in nursing infants from XARTEMIS XR, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

    8.4 Pediatric Use

    Safety and effectiveness of XARTEMIS XR in pediatric patients under the age of 18 years have not been established.

    8.5 Geriatric Use

    Of the 607 subjects in the Phase 3 studies treated with XARTEMIS XR, 63 (10.3%) were older than age 65, of which 10 (1.6%) were older than age 75. No untoward or unexpected adverse reactions were seen in the elderly patients who received oxycodone hydrochloride/acetaminophen extended-release tablets. However, special precaution should be given when determining the dosing amount and frequency of XARTEMIS XR for geriatric patients, since a greater sensitivity to oxycodone may be observed in this patient population when compared to younger patients.

    8.6 Hepatic Impairment

    XARTEMIS XR contains oxycodone and acetaminophen, which are extensively metabolized in the liver. Their clearance may be decreased in patients with hepatic impairment. In patients with hepatic impairment start with one tablet and adjust the dosage as needed. Monitor closely for respiratory depression [see Clinical Pharmacology (12.3)].

    8.7 Renal Impairment

    Information from oxycodone HCl indicates that patients with renal impairment (defined as a creatinine clearance <60 mL/min) had higher plasma concentrations of oxycodone than subjects with normal renal function.

    In patients with renal impairment start with one tablet and adjust the dosage as needed. Monitor closely for respiratory depression [see Clinical Pharmacology (12.3)].

  • 9 DRUG ABUSE AND DEPENDENCE

    9.1    Controlled Substance

    XARTEMIS XR contains oxycodone, a mu-opioid agonist of the morphine type and is a Schedule II controlled substance. XARTEMIS XR is subject to misuse, abuse, addiction and criminal diversion [see Warnings and Precautions (5.1)].

    9.2    Abuse

    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.

    Drug abuse is the intentional non-therapeutic use of an over-the-counter or prescription drug, even once, for its rewarding psychological or physiological effects. Drug abuse includes, but is not limited to the following examples: the use of a prescription or over-the-counter drug to get “high,” or the use of steroids for performance enhancement and muscle build-up.

    Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that develop after repeated substance use and include: 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 abuse 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” to obtain additional prescriptions is common among drug abusers and people suffering from untreated addiction.

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

    XARTEMIS XR, 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 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 the Abuse of XARTEMIS XR
    XARTEMIS XR is intended for oral use only. Abuse of XARTEMIS XR poses a risk of overdose and death. Abuse may occur by taking intact tablets in quantities greater than prescribed or without legitimate purpose, by crushing and chewing, or snorting the crushed formulation, or by injecting a solution made from the crushed formulation. The risk of overdose and death is increased with concurrent abuse of alcohol or other central nervous system depressants.

    With intravenous abuse, the inactive ingredients in XARTEMIS XR can result in death, local tissue necrosis, infection, pulmonary granulomas, and increased risk of endocarditis and valvular heart injury. Parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and HIV.

    9.3    Dependence

    Patients may exhibit tolerance to some of the effects of oxycodone. 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 symptoms after abrupt discontinuation or a significant dose reduction of a drug. Withdrawal also may be precipitated through the administration of drugs with opioid antagonist activity, e.g., naloxone or mixed agonist/antagonist analgesics (pentazocine, butorphanol, buprenorphine, nalbuphine). Physical dependence may not occur to a clinically significant degree until after several days to weeks of continued opioid usage.

    The opioid abstinence or withdrawal syndrome is characterized by some or all of the following: restlessness, lacrimation, rhinorrhea, yawning, perspiration, chills, myalgia, and mydriasis. Other 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. In patients suspected of having significant physical dependence, withdrawal symptoms may be reduced by tapering therapy.

    Infants born to mothers physically dependent on opioids will also be physically dependent and may exhibit respiratory difficulties and withdrawal symptoms [see Use in Specific Populations (8.1, 8.2)].

  • 10 OVERDOSAGE

    10.1      Signs and Symptoms

    Following an acute overdosage, toxicity may result from the oxycodone or the acetaminophen.

    Oxycodone
    Acute overdosage with opioids is often characterized by respiratory depression, somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and, sometimes, pulmonary edema, bradycardia, hypotension, and death. Marked mydriasis rather than miosis may be seen due to severe hypoxia in overdose situations [see Clinical Pharmacology (12.2)].

    Acetaminophen
    In acetaminophen overdosage, dose-dependent potentially fatal hepatic necrosis is the most serious adverse effect. Renal tubular necrosis, hypoglycemic coma, and coagulation defects may also occur.

    Early symptoms following a potentially hepatotoxic overdose may include: nausea, vomiting, diaphoresis, and general malaise. Clinical and laboratory evidence of hepatic toxicity may not be apparent until 48 to 72 hours post-ingestion.

    10.2      Treatment

    A single or multiple drug overdose with oxycodone and acetaminophen is a potentially lethal polydrug overdose, and consultation with a regional poison control center is recommended. Immediate treatment includes support of cardiorespiratory function and measures to reduce drug absorption. Oxygen, intravenous fluids, vasopressors, assisted ventilation, and other supportive measures should be employed as indicated.

    Oxycodone
    Primary attention should be given to the reestablishment of adequate respiratory exchange through provision of a patent airway and the institution of assisted or controlled ventilation. The opioid antagonist naloxone hydrochloride is a specific antidote against respiratory depression which may result from overdose or unusual sensitivity to opioids, including oxycodone. Since the duration of action of oxycodone may exceed that of the antagonist, the patient should be kept under continued surveillance, and repeated doses of the antagonist should be administered as needed to maintain adequate respiration.

    Opioid antagonists should not be administered in the absence of clinically significant respiratory or circulatory depression. Administer opioid antagonists cautiously to persons who are known, or suspected to be, physically dependent on XARTEMIS XR. In such cases, an abrupt or complete reversal of opioid effects may precipitate an acute abstinence syndrome. In an individual physically dependent on opioids, administration of the usual dose of the antagonist will precipitate an acute withdrawal syndrome. The severity of the withdrawal syndrome produced 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 agonist should be begun with care and by titration with smaller than usual doses of the agonist.

    Acetaminophen
    Gastric decontamination with activated charcoal should be administered just prior to N‑acetylcysteine (NAC) to decrease systemic absorption if acetaminophen ingestion is known or suspected to have occurred within a few hours of presentation. Serum acetaminophen levels should be obtained immediately if the patient presents 4 hours or more after ingestion to assess potential risk of hepatotoxicity; acetaminophen levels drawn less than 4 hours post-ingestion may be misleading. To obtain the best possible outcome, NAC should be administered as soon as possible where impending or evolving liver injury is suspected. Intravenous NAC may be administered when circumstances preclude oral administration.

    Vigorous supportive therapy is required in severe intoxication. Procedures to limit the continuing absorption of the drug must be readily performed since the hepatic injury is dose-dependent and occurs early in the course of intoxication.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Oxycodone HCl is an opioid agonist and is relatively selective for the mu receptor, although it can interact with other opioid receptors at higher doses. The principal therapeutic action of oxycodone is analgesia. Like all opioid agonists, there is no ceiling effect to analgesia.

    Acetaminophen is a non-opioid, non-salicylate analgesic, and antipyretic. The site and mechanism for the analgesic effect of acetaminophen has not been determined. The antipyretic effect of acetaminophen is accomplished through the inhibition of endogenous pyrogen action on the hypothalamic heat-regulating centers.

    12.2 Pharmacodynamics

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

    Oxycodone depresses the cough reflex by direct effect on the cough center in the medulla. Oxycodone 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 Gastrointestinal Tract and Other Smooth Muscle
    Gastric, biliary, and pancreatic secretions are decreased by oxycodone HCl. Oxycodone, like other opioid analgesics, produces some degree of nausea and vomiting which is caused by direct stimulation of the chemoreceptor trigger zone located in the medulla. The frequency and severity of emesis gradually diminishes with time.

    Oxycodone may cause a decrease in the secretion of hydrochloric acid in the stomach that reduces motility while increasing the tone of 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 Cardiovascular System
    Oxycodone, in therapeutic doses, produces peripheral vasodilation (arterial and venous), decreased peripheral resistance, and inhibits baroreceptor reflexes. Manifestations of histamine release and/or peripheral vasodilation may include pruritus, flushing, red eyes, sweating, and/or orthostatic hypotension.

    Caution must be used in hypovolemic patients, such as those suffering acute myocardial infarction, because oxycodone may cause or further aggravate their hypotension. Caution must also be used in patients with cor pulmonale who have received therapeutic doses of opioids.

    Endocrine System
    Opioid agonists have been shown to have a variety of effects on the secretion of hormones. Opioids inhibit the secretion of ACTH, cortisol, and luteinizing hormone (LH) in humans. They also stimulate prolactin, growth hormone (GH) secretion, and pancreatic secretion of insulin and glucagon in humans and other species, rats, and dogs. Thyroid stimulating hormone (TSH) has been shown to be both inhibited and stimulated by opioids.

    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.

    12.3 Pharmacokinetics

    XARTEMIS XR is an extended-release bilayer formulation of oxycodone and acetaminophen (immediate- and extended-release layers) which is not interchangeable with other oxycodone/acetaminophen products because of differing pharmacokinetic profiles that affect the frequency of administration. The activity of oxycodone hydrochloride is primarily due to the parent drug oxycodone.

    Absorption

    The oral bioavailability of oxycodone is 60 to 87%. Bioavailability (dose-normalized AUC and Cmax) of oxycodone and acetaminophen following single- and multiple-doses of XARTEMIS XR tablets is comparable to immediate-release products containing oxycodone or acetaminophen.

    Oxycodone plasma concentrations from this bilayer product are detectable within 30 minutes and reach a maximum concentration (Cmax) in 3 to 4 hours after XARTEMIS XR administration. Maximum plasma concentrations of acetaminophen occur in 0.75 to 1 hour after XARTEMIS XR administration.

    Steady-state plasma concentrations of oxycodone and acetaminophen are achieved within 24 hours of initiation of dosing of XARTEMIS XR (prior to the third dose of two XARTEMIS XR tablets administered every 12 hours). XARTEMIS XR produces steady-state maximum plasma concentrations of oxycodone that are greater than those following the first dose, while concentrations of acetaminophen are comparable to the first dose (Table 2).

    Food Effect

    When administered with a high- or low-fat meal, median Tmax values of oxycodone were delayed by 2 hours and 1 hour, respectively. Mean AUC values are increased by 15 to 16% and peak concentrations are 12 to 25% higher for oxycodone. Food delayed median acetaminophen Tmax by 1.5 hours. There is no change in mean acetaminophen AUC values and peak concentrations are 23 to 24% lower with food. XARTEMIS XR may be administered with or without food.

    Distribution

    Following intravenous administration, the volume of distribution (Vss) for oxycodone was 2.6 L/kg. Oxycodone was approximately 45% bound to plasma protein at 37°C and a pH of 7.4. Oxycodone has been found in breast milk [see Use in Specific Populations (8.3)].

    Acetaminophen appears to be widely distributed throughout most body tissues except fat. Its apparent volume of distribution is about 0.9 L/kg. A relative small portion (~20%) of acetaminophen is bound to plasma protein.

    Metabolism

    Oxycodone hydrochloride is extensively metabolized to noroxycodone, oxymorphone, and their glucuronides. The major circulating metabolite is noroxycodone with an AUC ratio of 0.6 relative to that of oxycodone. Oxymorphone is present in the plasma only in low concentrations. The analgesic activity profile of other metabolites is not known at present.

    The formation of oxymorphone, but not noroxycodone, is mediated by CYP2D6 and as such its formation can, in theory, be affected by other drugs [see Warnings and Precautions (5.4, 5.15)].

    Acetaminophen is primarily metabolized in the liver by first-order kinetics and involves three principal separate pathways:

    a) conjugation with glucuronide;

    b) conjugation with sulfate; and

    c) oxidation via the cytochrome, P450-dependent, mixed-function oxidase enzyme pathway to
        form a reactive intermediate metabolite, which conjugates with glutathione and is then
        further metabolized to form cysteine and mercapturic acid conjugates.

    The principal cytochrome P450 isoenzyme involved appears to be CYP2E1, with CYP1A2 and CYP3A4 as additional pathways.

    In adults, the majority of acetaminophen is conjugated with glucuronic acid and, to a lesser extent, with sulfate. These glucuronide-, sulfate-, and glutathione-derived metabolites lack biologic activity. In premature infants, newborns, and young infants, the sulfate conjugate predominates.

    Elimination

    Oxycodone and its metabolites are eliminated primarily via the kidney. The amounts measured in the urine have been reported as follows: free oxycodone up to 19%; conjugated oxycodone up to 50%; free oxymorphone 0%; and conjugated oxymorphone ≤14%. Both free and conjugated noroxycodone have been found in urine but not quantified. The total plasma clearance was 0.8 L/min for adults. Apparent elimination half-life (mean ± SD) of oxycodone following administration of XARTEMIS XR was 4.5 ± 0.6 hours as compared to 3.9 ± 0.3 hours for immediate-release oxycodone.

    Acetaminophen is eliminated from the body primarily by formation of glucuronide and sulfate conjugates in a dose-dependent manner Less than 9% of acetaminophen is excreted unchanged in urine. Following administration of XARTEMIS XR, the apparent elimination half-life is 5.8 ± 2.1 hours as compared to 4.1 ± 1.1 hours for immediate-release acetaminophen.

    Special Populations

    Elderly: Population pharmacokinetic studies indicate that the plasma concentrations of oxycodone did not appear to be increased in patients over the age of 65. A population pharmacokinetic analysis of data obtained from a clinical trial in patients with chronic pain which included 55 patients between 65 and 75 years of age and 19 patients over 75 years of age, showed no significant changes in the pharmacokinetics of acetaminophen in elderly patients with normal renal and hepatic function.

    Gender: Population pharmacokinetic analyses performed in a clinical study support the lack of gender effect on the pharmacokinetics of oxycodone.

    Hepatic Impairment: The pharmacokinetics of XARTEMIS XR in patients with impaired hepatic function has not been studied. Oxycodone and acetaminophen are extensively metabolized, resulting in decreased clearance in patients with hepatic impairment [see Use in Specific Populations (8.6)].

    Renal Impairment: The pharmacokinetics of XARTEMIS XR in patients with renal impairment has not been studied. Patients with renal impairment (defined as creatinine clearance <60 mL/min) have higher plasma concentrations of oxycodone than subjects with normal renal function [see Use in Specific Populations (8.7)].

  • 13 NONCLINICAL TOXICOLOGY

    13.1      Carcinogenesis, Mutagenesis, Impairment of Fertility

    No carcinogenicity, mutagenicity, or fertility studies were conducted with the combination of oxycodone and APAP, the components of XARTEMIS XR. The following data are based on findings from studies performed with the individual components.

    Carcinogenesis

    No animal studies to evaluate the carcinogenic potential of oxycodone have been conducted. Long-term studies in mice and rats have been completed by the National Toxicology Program to evaluate the carcinogenic potential of acetaminophen. In 2-year feeding studies, F344/N rats and B6C3F1 mice were fed a diet containing acetaminophen up to 6000 ppm. Female rats demonstrated equivocal evidence of carcinogenic activity based on increased incidences of mononuclear cell leukemia at 0.8 times the maximum human daily dose (MHDD) of 4 grams/day, based on a body surface area comparison. In contrast, there was no evidence of carcinogenic activity in male rats that received up to 0.7 times or mice at up to 1.2-1.4 times the MHDD, on a body surface area comparison.

    Mutagenesis

    Oxycodone hydrochloride was genotoxic in an in vitro mouse lymphoma assay in the presence of metabolic activation. There was no evidence of genotoxic potential in an in vitro bacterial reverse mutation assay (Salmonella typhimurium and Escherichia coli) or in an assay for chromosomal aberrations (in vivo mouse bone marrow micronucleus assay).

    Acetaminophen was not mutagenic in the bacterial reverse mutation assay (Ames test). In contrast, acetaminophen tested positive for induction of sister chromatid exchanges and chromosomal aberrations in in vitro assays using Chinese hamster ovary cells. In the published literature, acetaminophen has been reported to be clastogenic when administered a dose of 1500 mg/kg/day to the rat model (3.6-times the MHDD, based on a body surface area comparison). In contrast, no clastogenicity was noted at a dose of 750 mg/kg/day (1.8-times the MHDD, based on a body surface area comparison), suggesting a threshold effect.

    Impairment of Fertility

    No animal studies to evaluate the effect of oxycodone on male or female fertility have been conducted.

    In studies conducted by the National Toxicology Program, fertility assessments have been completed in Swiss CD-1 mice via a continuous breeding study. There were no effects on fertility parameters in mice consuming up to 1.7 times the MHDD of acetaminophen, based on a body surface area comparison. Although there was no effect on sperm motility or sperm density in the epididymis, there was a significant increase in the percentage of abnormal sperm in mice consuming 1.7 times the MHDD (based on a body surface area comparison) and there was a reduction in the number of mating pairs producing a fifth litter at this dose, suggesting the potential for cumulative toxicity with chronic administration of acetaminophen near the upper limit of daily dosing.

    Published studies in rodents report that oral acetaminophen treatment of male animals at doses that are 1.2 times the MHDD and greater (based on a body surface area comparison) result in decreased testicular weights, reduced spermatogenesis, reduced fertility, and reduced implantation sites in females given the same doses. These effects appear to increase with the duration of treatment. The clinical significance of these findings is not known.

  • 14 CLINICAL STUDIES

    Post-Operative Bunionectomy Pain Study

    Efficacy was demonstrated in one multicenter, randomized, double-blind, placebo-controlled, parallel-arm, multiple-dose clinical trial comparing XARTEMIS XR and placebo in patients with acute pain following a unilateral first metatarsal bunionectomy. A total of 303 patients with a mean age of 43 (range 18 to 73) years, meeting criteria for randomization (pain intensity ≥4 on a 0 to 10 numerical pain rating scale) and receiving a fixed-dose of 2 tablets of XARTEMIS XR 7.5 mg oxycodone hydrochloride and 325 mg acetaminophen tablets or placebo every 12 hours over 48 hours were randomized. There were 36 early discontinuations (9% from XARTEMIS XR, 13% from placebo). Ibuprofen 400 mg every 4 hours as needed was allowed as rescue medication.

    Mean baseline pain intensity scores were 6.2 in the XARTEMIS XR group (range: 4 to 10) and 6.0 in the placebo group (range: 1 to 10). Approximately 85% of the 150 subjects treated with XARTEMIS XR and 98% of the 153 subjects treated with placebo took rescue medication at least once for pain management during the 48 hours after the first dose. Median rescue medication use was 2 doses for XARTEMIS XR-treated subjects and 4 doses for placebo-treated subjects over the 48 hours; rescue medication was used by less than 50% of the XARTEMIS XR-treated patients after the first dose interval. Pain intensity was recorded at 2, 4, 8, and 12 hours after each dose, with additional recordings at 15, 30, 45, 60, and 90 minutes after the first dose. The median time to onset of pain relief was less than one hour for XARTEMIS XR. The primary endpoint was the summed pain intensity difference (change in pain from baseline) over 48 hours (SPID48), which demonstrated improvement in pain from baseline for the XARTEMIS XR treatment group compared to placebo.

  • Medication Guide

    XARTEMIS™ XR (ZAR-tem-iss) (oxycodone hydrochloride and acetaminophen) Extended-Release Tablets, CII

    XARTEMIS XR is:

    • A strong prescription pain medicine that contains an opioid (narcotic) and the medicine acetaminophen. XARTEMIS XR is used to treat certain types of short term (acute) pain.
    • A long-acting (extended-release) opioid pain medicine that can put you at risk for overdose and death. Even if you take your dose correctly as prescribed you are at risk for opioid addiction, abuse, and misuse that can lead to death.

    Important information about XARTEMIS XR:

    • Get emergency help right away if you take too much XARTEMIS XR (overdose). When you first start taking XARTEMIS XR, when your dose is changed, or if you take too much (overdose), serious or life-threatening breathing problems that can lead to death may occur.
    • Never give anyone else your XARTEMIS XR. They could die from taking it. Store XARTEMIS XR away from children and in a safe place to prevent stealing or abuse. Selling or giving away XARTEMIS XR is against the law.
    • Get emergency help right away if you take more than 4,000 mg of acetaminophen in 1 day. Taking XARTEMIS XR with other products that contain acetaminophen can lead to serious liver problems and death.

    Do not take XARTEMIS XR if you have:

    • severe asthma, trouble breathing, or other lung problems.
    • allergy to acetaminophen or oxycodone.
    • a bowel blockage or have narrowing of the stomach or intestines.

    Before taking XARTEMIS XR, tell your healthcare provider if you have a history of:

    • head injury, seizures 
    • problems urinating
    • abuse of street or prescription drugs, alcohol addiction, or mental health problems.
    • liver, kidney, thyroid problems       
    • pancreas or gallbladder problems

    Tell your healthcare provider if you are:

    • pregnant or planning to become pregnant. Prolonged use during pregnancy can cause life-threatening withdrawal symptoms in your newborn baby if not recognized and treated.
    • breastfeeding. XARTEMIS XR passes into breast milk and may harm your baby.
    • taking prescription or over-the-counter medicines, vitamins, or herbal supplements. Taking XARTEMIS XR with certain other medicines can cause serious side effects.

    When taking XARTEMIS XR:

    • Do not change your dose. Take XARTEMIS XR exactly as prescribed by your healthcare provider.
    • Take your prescribed dose every 12 hours, at the same time every day. If you miss a dose, take XARTEMIS XR as soon as possible, then take your next dose 12 hours later. If it is almost time for your next dose, skip the missed dose. Take your next dose at the regular time. Do not take more than your prescribed daily dose in 24 hours.
    • Swallow XARTEMIS XR whole. Do not cut, break, chew, crush, dissolve, snort or inject XARTEMIS XR because this may cause you to overdose and die. You should not receive XARTEMIS XR through a nasogastric tube or gastric tube (stomach tube).
    • Take XARTEMIS XR 1 tablet at a time. Do not pre-soak, lick, or wet the tablet before placing in your mouth. Take each XARTEMIS XR tablet with enough water to be sure that you swallow it completely as soon as you place it in your mouth.
    • Call your healthcare provider if XARTEMIS XR does not control your pain.
    • If you have been taking XARTEMIS XR for more than a few days, do not stop taking it without talking to your healthcare provider.
    • After you stop taking XARTEMIS XR, flush any unused tablets down the toilet.

    While taking XARTEMIS XR:

    • Do not drive or operate heavy machinery, until you know how XARTEMIS XR affects you. XARTEMIS XR can make you sleepy, dizzy, or lightheaded.
    • Do not drink alcohol.
    • Do not take other products that contain acetaminophen while taking XARTEMIS XR.

    The possible side effects of XARTEMIS XR are:

    • nausea, dizziness, headache, vomiting, constipation, sleepiness. Call your healthcare provider if you have any of these symptoms and they are severe.

    Get emergency medical help if you have:

    • trouble breathing, shortness of breath, fast heartbeat, chest pain, swelling of your face, tongue or throat, extreme drowsiness, low blood pressure when changing positions, or you are feeling faint.
    • rash with hives, sores in your mouth or eyes, or your skin blisters and peels.
