PHARMACOKINETIC ASSESSMENT

If Manipulated and Used Intranasally, RoxyBond has Lower Plasma Concentrations and Slower Time to Peak1,2

Plasma concentration alone is not sufficient to determine abuse potential.

Study design1,2: The intranasal abuse potential and relative bioavailability of RoxyBond was evaluated in a randomized, double-blind, double-dummy, placebo-controlled, single-dose, 4-way crossover study in 29 nondependent recreational opioid users comparing crushed intranasal RoxyBond 30 mg, crushed intranasal oxycodone IR 30 mg, and intact oral RoxyBond 30 mg.

  • Primary endpoint: mean maximum effect (Emax) for Drug Liking between crushed intranasal RoxyBond and crushed intranasal oxycodone IR
  • Secondary endpoints included Take Drug Again and Ease of Snorting assessments and determining the relative bioavailability of oxycodone in plasma for crushed intranasal and intact oral RoxyBond compared with crushed intranasal oxycodone IR
  • Drug Liking (primary) and Take Drug Again (secondary) endpoints were measured on a 100 mm bipolar visual analog scale (VAS) where 50 represents a neutral response, 0 represents the strongest negative response, and 100 represents the strongest positive response

INDICATION

ROXYBOND is indicated for the management of 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, which can occur any dosage or duration, reserve ROXYBOND 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.
ROXYBOND should not be used for an extended period of time unless the pain remains severe enough to require an opioid analgesic and for which alternative treatment options continue to be inadequate.

IMPORTANT SAFETY INFORMATION

WARNING: SERIOUS AND LIFE-THREATENING RISKS FROM USE OF ROXYBOND


Addiction, Abuse, and Misuse
Because the use of ROXYBOND 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 and reassess all patients regularly for the development of these behaviors and conditions. 

Life-Threatening Respiratory Depression
Serious, life-threatening, or fatal respiratory depression may occur with use of ROXYBOND, especially during initiation or following a dosage increase. To reduce the risk of respiratory depression, proper dosing and titration of ROXYBOND are essential.

Accidental Ingestion
Accidental ingestion of even one dose of ROXYBOND, especially by children, can result in a fatal overdose of oxycodone.

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. Reserve concomitant prescribing of ROXYBOND and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate.

Neonatal Opioid Withdrawal Syndrome (NOWS)
If opioid use is required for an extended period of time in a pregnant woman, advise the patient of the risk of NOWS, which may be life-threatening if not recognized and treated. Ensure that management by neonatology experts will be available at delivery. 


Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS)
Healthcare providers are strongly encouraged to complete a REMS-compliant education program and to counsel patients and caregivers on serious risks, safe use, and the importance of reading the Medication Guide with each prescription.


Cytochrome P450 3A4 Interaction
The concomitant use of ROXYBOND with all cytochrome P450 3A4 inhibitors may result in an increase in oxycodone plasma concentrations, which could increase or prolong adverse reactions and may cause potentially fatal respiratory depression. In addition, discontinuation of a concomitantly used cytochrome P450 3A4 inducer may result in an increase in oxycodone plasma concentration.  Regularly evaluate patients receiving ROXYBOND and any CYP3A4 inhibitor or inducer.

CONTRAINDICATIONS

ROXYBOND is contraindicated in patients with:

  • Significant respiratory depression
  • Acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment or hypercarbia
  • Known or suspected gastrointestinal obstruction, including paralytic ileus
  • Known hypersensitivity (e.g., anaphylaxis) to oxycodone

WARNINGS AND PRECAUTIONS

Addiction, Abuse, and Misuse

ROXYBOND contains oxycodone, a Schedule II controlled substance.  As an opioid, ROXYBOND exposes users to the risks of addiction, abuse, and misuse.

Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed ROXYBOND.  Addiction can occur at recommended dosages, when taken as directed, and if the drug is misused or abused.

Assess each patient’s risk for opioid addiction, abuse, or misuse prior to prescribing ROXYBOND, and reassess all patients receiving ROXYBOND 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 ROXYBOND but use in such patients necessitates intensive counseling about the risks and proper use of ROXYBOND along with frequent reevaluation for signs of addiction, abuse, and misuse.  Consider prescribing naloxone for the emergency treatment of opioid overdose.

Opioids are sought for nonmedical use and are subject to diversion from legitimate prescribed use.  Consider these risks when prescribing or dispensing ROXYBOND.  Strategies to reduce these risks include prescribing the drug in the smallest appropriate quantity and advising the patient on careful storage of the drug during the course of treatment and on the proper disposal of unused drugs.  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.

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.  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 ROXYBOND, the risk is greatest during the initiation of therapy or following a dosage increase.

To reduce the risk of respiratory depression, proper dosing and titration of ROXYBOND are essential.  Overestimating the ROXYBOND dosage when converting patients from another opioid product can result in fatal overdose with the first dose.

Accidental ingestion of even one dose of ROXYBOND, especially by children, can result in respiratory depression and death due to an overdose of oxycodone.

Educate patients and caregivers on how to recognize respiratory depression and emphasize on the importance of calling 911 or getting emergency medical help right away in the event of a known or suspected overdose.

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.

Patient Access to Naloxone for the Emergency Treatment of Opioid Overdose

Discuss the availability of naloxone for the emergency treatment of opioid overdose with the patient and caregiver and assess the potential need for access to naloxone, both when initiating and renewing the treatment with ROXYBOND.  Inform patients and caregivers about the various ways to obtain naloxone as permitted by individual state naloxone dispensing and prescribing requirements or guidelines (e.g., by prescription, directly from a pharmacist, or as part of a community-based program).  Educate patients and caregivers on how to recognize respiratory depression and emphasize the importance of calling 911 or getting emergency medical help, even if naloxone is administered.

Consider prescribing naloxone, based on the patient’s risk factors for overdose, such as concomitant use of CNS depressants, a history of opioid use disorder, or prior opioid overdose.  The presence of risk factors for overdose should not prevent the proper management of pain in any given patient.  Also consider prescribing naloxone if the patient has household members (including children) or other close contacts at risk for accidental ingestion or overdose.  If naloxone is prescribed, educate patients and caregivers on how to treat with naloxone.

Risks from Concomitant Use with Benzodiazepines or Other CNS Depressants

Profound sedation, respiratory depression, coma, and death may result from the concomitant use of ROXYBOND with benzodiazepines and/or other CNS depressants, including alcohol (e.g., non-benzodiazepine sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids).  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.

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. Inform patients and caregivers of this potential interaction and educate them on the signs and symptoms of respiratory depression (including sedation).  If concomitant use is warranted, consider prescribing naloxone for the emergency treatment of opioid overdose.

Advise both patients and caregivers about the risks of respiratory depression and sedation when ROXYBOND is used with benzodiazepines or other CNS depressants (including alcohol and illicit drugs).  Advise patients not to drive or operate dangerous 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.

Neonatal Opioid Withdrawal Syndrome (NOWS)

Use of ROXYBOND for an extended period of time 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 an extended period of time of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.

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.

Risks of Concomitant Use or Discontinuation of Cytochrome P450 3A4 Inhibitors and Inducers

Concomitant use of ROXYBOND with a CYP3A4 inhibitor, 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 adverse reactions, which may cause potentially fatal respiratory depression, particularly when an inhibitor is added after a stable dose of ROXYBOND is achieved.  Similarly, discontinuation of a CYP3A4 inducer, such as rifampin, carbamazepine, and phenytoin, in ROXYBOND-treated patients may increase oxycodone plasma concentrations and prolong opioid adverse reactions.  When using ROXYBOND with CYP3A4 inhibitors or discontinuing CYP3A4 inducers in ROXYBOND-treated patients, evaluate patients at frequent intervals and consider dosage reduction of ROXYBOND until stable drugs effects are achieved.

Concomitant use of ROXYBOND with CYP3A4 inducers or discontinuation of a CYP3A4 inhibitor could decrease oxycodone plasma concentrations, decrease opioid efficacy or, possibly, lead to a withdrawal syndrome in a patient who had developed physical dependence to oxycodone.  When using ROXYBOND with CYP3A4 inducers or discontinuing CYP3A4 inhibitors, evaluate patients at frequent intervals and consider increasing the opioid dosage if needed to maintain adequate analgesia or if symptoms of opioid withdrawal occur.

Opioid-Induced Hyperalgesia and Allodynia
Opioid-Induced Hyperalgesia (OIH) occurs when an opioid analgesic paradoxically causes an increase in pain, or an increase in sensitivity to pain.  This condition differs from tolerance, which is the need for increasing doses of opioids to maintain a defined effect. Symptoms of OIH include (but may not be limited to) increased levels of pain upon opioid dosage increase, decreased levels of pain upon opioid dosage decrease, or pain from ordinarily non-painful stimuli (allodynia).  These symptoms may suggest OIH only if there is no evidence of underlying disease progression, opioid tolerance, opioid withdrawal, or addictive behavior. 
Cases of OIH have been reported, both with short-term and longer-term use of opioid analgesics. Though the mechanism of OIH is not fully understood, multiple biochemical pathways have been implicated. Medical literature suggests a strong biologic plausibility between opioid analgesics and OIH and allodynia. If a patient is suspected to be experiencing OIH, carefully consider appropriately decreasing the dose of the current opioid analgesic or opioid rotation (safely switching the patient to a different opioid moiety).

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

The use of ROXYBOND 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: ROXYBOND-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 ROXYBOND.

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.

Regularly evaluate patients, particularly when initiating and titrating ROXYBOND and when ROXYBOND is given concomitantly with other drugs that depress respiration. Alternatively, consider the use of non-opioid analgesics in these patients.

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.

Severe Hypotension

ROXYBOND 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).  Regularly evaluate these patients for signs of hypotension after initiating or titrating the dosage of ROXYBOND.  In patients with circulatory shock, use of ROXYBOND may cause vasodilation that can further reduce cardiac output and blood pressure.  Avoid use of ROXYBOND in patients with circulatory shock.

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), ROXYBOND may reduce the 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 ROXYBOND.

Opioids may obscure the clinical course in a patient with a head injury.  Avoid the use of ROXYBOND in patients with impaired consciousness or coma.

Risks of Use in Patients with Gastrointestinal Conditions

ROXYBOND is contraindicated in patients with gastrointestinal obstruction, including paralytic ileus.

The oxycodone in ROXYBOND may cause spasm of the sphincter of Oddi.  Opioids may cause increases in serum amylase.  Regularly evaluate patients with biliary tract disease, including acute pancreatitis, for worsening symptoms.

Increased Risk of Seizures in Patients with Seizure Disorders

The oxycodone in ROXYBOND 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.  Regularly evaluate patients with a history of seizure disorders for worsened seizure control during ROXYBOND therapy.

Withdrawal

Do not abruptly discontinue ROXYBOND in a patient physically dependent on opioids.  When discontinuing ROXYBOND in a physically-dependent patient, gradually taper the dosage.  Rapid tapering of oxycodone in a patient physically dependent on opioids may lead to a withdrawal syndrome and return of pain.

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 ROXYBOND.  In these patients, mixed agonist/antagonist and partial agonist analgesics may reduce the analgesic effect and/or precipitate withdrawal symptoms.

Risks of Driving and Operating Machinery

ROXYBOND 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 ROXYBOND and know how they will react to the medication.

ADVERSE REACTIONS

The common adverse reactions seen on initiation of therapy with oxycodone hydrochloride tablets are dose related and are opioid related adverse reactions. The most frequent of these included nausea, constipation, vomiting, headache, pruritus, insomnia, dizziness, asthenia, and somnolence.

DRUG INTERACTIONS

  • Concomitant use of ROXYBOND with a CYP3A4 and CYP2D6 inhibitor, 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 adverse reactions, which may cause potentially fatal respiratory depression, particularly when an inhibitor is added after a stable dose of ROXYBOND is achieved.
  • Concomitant use of ROXYBOND and CYP3A4 inducers can decrease the plasma concentration of oxycodone, resulting in decreased efficacy or onset of a withdrawal syndrome in patients who have developed physical dependence to oxycodone.
  • Due to additive pharmacologic effect, the concomitant use of benzodiazepines or other CNS depressants, including alcohol, can increase the risk of hypotension, respiratory depression, profound sedation, coma, and death.
  • The concomitant use of opioids with other drugs that affect the serotonergic neurotransmitter system has resulted in serotonin syndrome.
  • MAOI interactions with opioids may manifest as serotonin syndrome or opioid toxicity.
  • Mixed agonist/antagonist and partial agonist opioid analgesics may reduce the analgesic effect of ROXYBOND and/or may precipitate withdrawal symptoms.
  • Oxycodone may enhance the neuromuscular blocking action of skeletal muscle relaxants and produce an increased degree of respiratory depression.
  • Opioids can reduce the efficacy of diuretics by inducing the release of antidiuretic hormone.
  • The concomitant use of anticholinergic drugs may increase risk of urinary retention and/or severe constipation, which may lead to paralytic ileus.

Risks from Concomitant Use with Benzodiazepines or Other CNS Depressants

Profound sedation, respiratory depression, coma, and death may result from the concomitant use of ROXYBOND with benzodiazepines and/or other CNS depressants, including alcohol (e.g., non-benzodiazepine sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids).  Because of these risks, reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate.

Risks of Concomitant Use or Discontinuation of Cytochrome P450 3A4 Inhibitors and Inducers

Concomitant use of ROXYBOND with a CYP3A4 inhibitor, 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 adverse reactions, which may cause potentially fatal respiratory depression, particularly when an inhibitor is added after a stable dose of ROXYBOND is achieved.  Similarly, discontinuation of a CYP3A4 inducer, such as rifampin, carbamazepine, and phenytoin, in ROXYBOND-treated patients may increase oxycodone plasma concentrations and prolong opioid adverse reactions.  When using ROXYBOND with CYP3A4 inhibitors or discontinuing CYP3A4 inducers in ROXYBOND-treated patients, evaluate patients at frequent intervals and consider dosage reduction of ROXYBOND until stable drugs effects are achieved.

Concomitant use of ROXYBOND with CYP3A4 inducers or discontinuation of a CYP3A4 inhibitor could decrease oxycodone plasma concentrations, decrease opioid efficacy or, possibly, lead to a withdrawal syndrome in a patient who had developed physical dependence to oxycodone.  When using ROXYBOND with CYP3A4 inducers or discontinuing CYP3A4 inhibitors, evaluate patients at frequent intervals and consider increasing the opioid dosage if needed to maintain adequate analgesia or if symptoms of opioid withdrawal occur.

Opioid-Induced Hyperalgesia and Allodynia
Opioid-Induced Hyperalgesia (OIH) occurs when an opioid analgesic paradoxically causes an increase in pain, or an increase in sensitivity to pain.  This condition differs from tolerance, which is the need for increasing doses of opioids to maintain a defined effect. Symptoms of OIH include (but may not be limited to) increased levels of pain upon opioid dosage increase, decreased levels of pain upon opioid dosage decrease, or pain from ordinarily non-painful stimuli (allodynia).  These symptoms may suggest OIH only if there is no evidence of underlying disease progression, opioid tolerance, opioid withdrawal, or addictive behavior. 
Cases of OIH have been reported, both with short-term and longer-term use of opioid analgesics. Though the mechanism of OIH is not fully understood, multiple biochemical pathways have been implicated. Medical literature suggests a strong biologic plausibility between opioid analgesics and OIH and allodynia. If a patient is suspected to be experiencing OIH, carefully consider appropriately decreasing the dose of the current opioid analgesic or opioid rotation (safely switching the patient to a different opioid moiety).

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

The use of ROXYBOND 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: ROXYBOND-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 ROXYBOND.

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.

Regularly evaluate patients, particularly when initiating and titrating ROXYBOND and when ROXYBOND is given concomitantly with other drugs that depress respiration. Alternatively, consider the use of non-opioid analgesics in these patients.

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.

Severe Hypotension

ROXYBOND 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).  Regularly evaluate these patients for signs of hypotension after initiating or titrating the dosage of ROXYBOND.  In patients with circulatory shock, use of ROXYBOND may cause vasodilation that can further reduce cardiac output and blood pressure.  Avoid use of ROXYBOND in patients with circulatory shock.

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), ROXYBOND may reduce the 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 ROXYBOND.

Opioids may obscure the clinical course in a patient with a head injury.  Avoid the use of ROXYBOND in patients with impaired consciousness or coma.

Risks of Use in Patients with Gastrointestinal Conditions

ROXYBOND is contraindicated in patients with gastrointestinal obstruction, including paralytic ileus.

The oxycodone in ROXYBOND may cause spasm of the sphincter of Oddi.  Opioids may cause increases in serum amylase.  Regularly evaluate patients with biliary tract disease, including acute pancreatitis, for worsening symptoms.

Increased Risk of Seizures in Patients with Seizure Disorders

The oxycodone in ROXYBOND 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.  Regularly evaluate patients with a history of seizure disorders for worsened seizure control during ROXYBOND therapy.

Withdrawal

Do not abruptly discontinue ROXYBOND in a patient physically dependent on opioids.  When discontinuing ROXYBOND in a physically-dependent patient, gradually taper the dosage.  Rapid tapering of oxycodone in a patient physically dependent on opioids may lead to a withdrawal syndrome and return of pain.

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 ROXYBOND.  In these patients, mixed agonist/antagonist and partial agonist analgesics may reduce the analgesic effect and/or precipitate withdrawal symptoms.

Risks of Driving and Operating Machinery

ROXYBOND 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 ROXYBOND and know how they will react to the medication.

ADVERSE REACTIONS

The common adverse reactions seen on initiation of therapy with oxycodone hydrochloride tablets are dose related and are opioid related adverse reactions. The most frequent of these included nausea, constipation, vomiting, headache, pruritus, insomnia, dizziness, asthenia, and somnolence.

DRUG INTERACTIONS

  • Concomitant use of ROXYBOND with a CYP3A4 and CYP2D6 inhibitor, 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 adverse reactions, which may cause potentially fatal respiratory depression, particularly when an inhibitor is added after a stable dose of ROXYBOND is achieved.
  • Concomitant use of ROXYBOND and CYP3A4 inducers can decrease the plasma concentration of oxycodone, resulting in decreased efficacy or onset of a withdrawal syndrome in patients who have developed physical dependence to oxycodone.
  • Due to additive pharmacologic effect, the concomitant use of benzodiazepines or other CNS depressants, including alcohol, can increase the risk of hypotension, respiratory depression, profound sedation, coma, and death.
  • The concomitant use of opioids with other drugs that affect the serotonergic neurotransmitter system has resulted in serotonin syndrome.
  • MAOI interactions with opioids may manifest as serotonin syndrome or opioid toxicity.
  • Mixed agonist/antagonist and partial agonist opioid analgesics may reduce the analgesic effect of ROXYBOND and/or may precipitate withdrawal symptoms.
  • Oxycodone may enhance the neuromuscular blocking action of skeletal muscle relaxants and produce an increased degree of respiratory depression.
  • Opioids can reduce the efficacy of diuretics by inducing the release of antidiuretic hormone.
  • The concomitant use of anticholinergic drugs may increase risk of urinary retention and/or severe constipation, which may lead to paralytic ileus.
