Oxycodone and Ibuprofen

Dosage Forms

Excipient information presented when available (limited, particularly for generics); consult specific product labeling.

Tablet: Oxycodone hydrochloride 5 mg and ibuprofen 400 mg

Pharmacology

Mechanism of Action

Oxycodone: Binds to opiate receptors in the CNS, causing inhibition of ascending pain pathways, altering the perception of and response to pain; produces generalized CNS depression

Ibuprofen: Reversibly inhibits cyclooxygenase-1 and 2 (COX-1 and 2) enzymes, which result in decreased formation of prostaglandin precursors; has antipyretic, analgesic, and anti-inflammatory properties

Pharmacokinetics/Pharmacodynamics

Absorption

Rapidly absorbed

Time to Peak

Serum: Ibuprofen: 1.6 to 3.1 hours; Oxycodone 1.3 to 2.1 hours

Use: Labeled Indications

Pain: Short-term (≤7 days) management of acute to moderate pain severe enough to require opioid treatment and for which alternative treatments are inadequate.

Limitations of use: Reserve oxycodone/ibuprofen for use in patients for whom alternative treatment options [eg, non-opioid analgesics] have not been tolerated, or are not expected to be tolerated, and have not provided adequate analgesia, or are not expected to provide adequate analgesia.

Contraindications

Hypersensitivity to oxycodone, ibuprofen, other opioids, or any component of the formulation; paralytic ileus (known or suspected); use in the setting of coronary artery bypass graft (CABG) surgery; significant respiratory depression; acute or severe bronchial asthma or hypercarbia (in an unmonitored setting or in the absence of resuscitative equipment); history of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs.

Dosage and Administration

Dosing: Adult

Pain: Oral: Oxycodone 5 mg/ibuprofen 400 mg (1 tablet) every 6 hours as needed (maximum: oxycodone 20 mg/ibuprofen 1,600 mg [4 tablets] per 24 hours); do not take for longer than 7 days.

Discontinuation of therapy: When discontinuing chronic opioid therapy, the dose should be gradually tapered down. An optimal universal tapering schedule for all patients has not been established (CDC [Dowell 2016]). Proposed schedules range from slow (eg, 10% reductions per week) to rapid (eg, 25% to 50% reduction every few days) (CDC 2015). Tapering schedules should be individualized to minimize opioid withdrawal while considering patient-specific goals and concerns as well as the pharmacokinetics of the opioid being tapered. An even slower taper may be appropriate in patients who have been receiving opioids for a long duration (eg, years), particularly in the final stage of tapering, whereas more rapid tapers may be appropriate in patients experiencing severe adverse events (CDC [Dowell 2016]). Monitor carefully for signs/symptoms of withdrawal. If the patient displays withdrawal symptoms, consider slowing the taper schedule; alterations may include increasing the interval between dose reductions, decreasing amount of daily dose reduction, pausing the taper and restarting when the patient is ready, and/or coadministration of an alpha-2 agonist (eg, clonidine) to blunt withdrawal symptoms (Berna 2015; CDC [Dowell 2016]). Continue to offer nonopioid analgesics as needed for pain management during the taper; consider nonopioid adjunctive treatments for withdrawal symptoms (eg, GI complaints, muscle spasm) as needed (Berna 2015; Sevarino 2019).

Warnings/Precautions

Concerns related to adverse effects:

• Anaphylactoid reactions: Even in patients without prior exposure anaphylactoid reactions may occur; patients with "aspirin triad" (bronchial asthma, aspirin intolerance, rhinitis) may be at increased risk. Contraindicated in patients who experience bronchospasm, asthma, rhinitis, or urticaria with NSAID or aspirin therapy.
• Cardiovascular events: [US Boxed Warning]: NSAIDs cause an increased risk of serious (and potentially fatal) adverse cardiovascular thrombotic events, including fatal MI and stroke. Risk may occur early during treatment and may increase with duration of use. Relative risk appears to be similar in those with and without known cardiovascular disease or risk factors for cardiovascular disease; however, absolute incidence of serious cardiovascular thrombotic events (which may occur early during treatment) was higher in patients with known cardiovascular disease or risk factors and in those receiving higher doses. New onset hypertension or exacerbation of hypertension may occur (NSAIDs may also impair response to ACE inhibitors, thiazide diuretics, or loop diuretics); may contribute to cardiovascular events; monitor blood pressure; use with caution in patients with hypertension. May cause sodium and fluid retention; use with caution in patients with edema. Avoid use in heart failure (ACCF/AHA [Yancy, 2013]). Avoid use in patients with a recent MI unless benefits outweigh risk of cardiovascular thrombotic events. Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals, to reduce risk of cardiovascular events; alternate therapies should be considered for patients at high risk.
• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks that require mental alertness (eg, operating machinery, driving).
• Constipation: Oxycodone may cause constipation which may be problematic in patients with unstable angina and patients post-myocardial infarction. Consider preventive measures (eg, stool softener, increased fiber) to reduce the potential for constipation.
• GI events: [US Boxed Warning]: NSAIDs cause an increased risk of serious GI inflammation, ulceration, bleeding, and perforation (may be fatal); elderly patients and patients with history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events. These events may occur at any time during therapy and without warning. Avoid use in patients with active GI bleeding. In patients with a history of acute lower GI bleeding, avoid use of non-aspirin NSAIDs, especially if due to angioectasia or diverticulosis (Strate 2016). Use caution with a history of GI ulcers, concurrent therapy known to increase the risk of GI bleeding (eg, aspirin, anticoagulants and/or corticosteroids, selective serotonin reuptake inhibitors), advanced hepatic disease, coagulopathy, smoking, use of alcohol, or in elderly or debilitated patients. Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals, to reduce risk of GI adverse events; alternate therapies should be considered for patients at high risk. When used concomitantly with aspirin, a substantial increase in the risk of GI complications (eg, ulcer) occurs; concomitant gastroprotective therapy (eg, proton pump inhibitors) is recommended (Bhatt 2008).
• Hematologic effects: Platelet adhesion and aggregation may be decreased with NSAID use; may prolong bleeding time; patients with coagulation disorders or who are receiving anticoagulants should be monitored closely. Anemia may occur; patients on long-term NSAID therapy should be monitored for anemia. Rarely, NSAID use has been associated with potentially severe blood dyscrasias (eg, agranulocytosis, thrombocytopenia, aplastic anemia).
• Hepatic effects: Transaminase elevations have been reported with NSAID use; closely monitor patients with any abnormal LFT. Rare (sometimes fatal) severe hepatic reactions (eg, fulminant hepatitis, liver necrosis, hepatic failure) have occurred; discontinue immediately if signs or symptoms of hepatic disease develop or if systemic manifestations occur.
• Hyperkalemia: NSAID use may increase the risk of hyperkalemia, particularly in elderly patients, diabetic patients, those with renal disease, and with concomitant use of other agents capable of inducing hyperkalemia (eg, ACE inhibitors). Monitor potassium closely.
• Hypotension: Oxycodone may cause severe hypotension (including orthostatic hypotension and syncope); use with caution in patients with hypovolemia, cardiovascular disease (including acute MI), or drugs that may exaggerate hypotensive effects (including phenothiazines or general anesthetics). Monitor for symptoms of hypotension following initiation or dose titration. Use caution in patients with circulatory shock.
• Phenanthrene hypersensitivity: Use oxycodone with caution in patients with hypersensitivity reactions to other phenanthrene-derivative opioid agonists (codeine, hydrocodone, hydromorphone, levorphanol, oxymorphone).
• Renal effects: NSAID use may compromise existing renal function; dose-dependent decreases in prostaglandin synthesis may result from NSAID use, reducing renal blood flow which may cause renal decompensation (usually reversible). Patients with impaired renal function, dehydration, hypovolemia, heart failure, hepatic impairment, those taking diuretics, and ACE inhibitors, and elderly patients are at greater risk of renal toxicity. Rehydrate patient before starting therapy; monitor renal function closely. Long-term NSAID use may result in renal papillary necrosis and other renal injury.
• Respiratory depression: [US Boxed Warning]: Serious, life-threatening, or fatal respiratory depression may occur with the use of oxycodone/ibuprofen. Monitor for respiratory depression, especially during initiation of therapy or following a dose increase. Carbon dioxide retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids.
• Skin reactions: NSAIDs may cause potentially fatal serious skin adverse events including exfoliative dermatitis, Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN); may occur without warning; discontinue use at first appearance of skin rash (or any other sign of hypersensitivity).

Disease-related concerns:

• Abdominal conditions: Oxycodone may obscure diagnosis or clinical course of patients with acute abdominal conditions.
• Adrenocortical insufficiency: Use oxycodone with caution in patients with adrenocortical insufficiency, including Addison disease. Long-term opioid use may cause secondary hypogonadism, which may lead to sexual dysfunction, infertility, mood disorders, and osteoporosis (Brennan 2013).
• Aseptic meningitis: NSAIDs increase the risk of aseptic meningitis, especially in patients with systemic lupus erythematosus (SLE) and mixed connective tissue disorders.
• Asthma: NSAIDs are contraindicated in patients with aspirin-sensitive asthma; severe and potentially fatal bronchospasm may occur. Use with caution in patients with other forms of asthma.
• Bariatric surgery: Gastric ulceration: Avoid chronic use of oral nonselective NSAIDs after bariatric surgery; development of anastomotic ulcerations/perforations may occur (Bhangu 2014; Mechanick 2013). Short-term use of celecoxib or IV ketorolac are recommended as part of a multimodal pain management strategy for postoperative pain (Chou 2016; Horsley 2019; Thorell 2016).
• Biliary tract impairment: Use oxycodone with caution in patients with biliary tract dysfunction, including acute pancreatitis; may cause constriction of sphincter of Oddi diminishing biliary and pancreatic secretions.
• CNS depression/coma: Avoid the use of oxycodone in patients with CNS depression or coma as these patients are susceptible to intracranial effects of CO₂ retention.
• Coronary artery bypass graft surgery: [US Boxed Warning]: Use is contraindicated in the setting of coronary artery bypass graft (CABG) surgery. Risk of MI and stroke may be increased with use following CABG surgery.
• Delirium tremens: Use oxycodone with caution in patients with delirium tremens.
• Head trauma: Use oxycodone with extreme caution in patients with head injury, intracranial lesions, or elevated intracranial pressure (ICP); exaggerated elevation of ICP may occur.
• Hepatic impairment: Use with caution in patients with severe hepatic impairment; patients with advanced hepatic disease are at an increased risk of GI bleeding with NSAIDs.
• Obesity: Use oxycodone with caution in patients who are morbidly obese (APS 2008).
• Prostatic hyperplasia/urinary stricture: Use oxycodone with caution in patients with prostatic hyperplasia and/or urinary stricture.
• Psychosis: Use oxycodone with caution in patients with toxic psychosis.
• Renal impairment: Avoid use of NSAIDs in patients with advanced renal disease.
• Respiratory disease: Use oxycodone with caution and monitor for respiratory depression in patients with significant chronic obstructive pulmonary disease or cor pulmonale, and patients having a substantially decreased respiratory reserve, hypoxia, or preexisting respiratory depression, particularly when initiating therapy and titrating dose; even therapeutic doses may decrease respiratory drive to the point of apnea. Consider the use of alternative nonopioid analgesics in these patients.
• Seizures: Use oxycodone with caution in patients with a history of seizure disorders; may cause or exacerbate preexisting seizures.
• Sleep-related disorders: Opioid use increases the risk for sleep-related disorders (eg, central sleep apnea [CSA], hypoxemia) in a dose-dependent fashion. Use with caution for chronic pain and titrate dosage cautiously in patients with risk factors for sleep-disordered breathing (eg, heart failure, obesity). Consider dose reduction in patients presenting with CSA. Avoid opioids in patients with moderate to severe sleep-disordered breathing (CDC [Dowell 2016]).
• Thyroid dysfunction: Use oxycodone with caution in patients with thyroid dysfunction.

Concurrent drug therapy issues:

• Benzodiazepines or other CNS depressants: [US Boxed Warning]: Concomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of oxycodone/ibuprofen and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate. Limit dosage and durations to the minimum required and follow patients for signs and symptoms of respiratory depression and sedation.
• CYP 3A4 interactions: [US Boxed Warning]: The concomitant use of oxycodone/ibuprofen with all cytochrome P450 (CYP-450) 3A4 inhibitors may result in an increase in oxycodone/ibuprofen plasma concentrations, which could increase or prolong adverse reactions and may cause potentially fatal respiratory depression. In addition, discontinuation of a concomitant CYP 3A4 inducer may result in increased oxycodone/ibuprofen plasma concentration. Monitor patients receiving oxycodone/ibuprofen and any CYP 3A4 inhibitor or inducer.
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Special populations:

• Cachectic or debilitated patients: Use oxycodone with caution in debilitated or cachectic patients; there is a greater potential for critical respiratory depression, even at therapeutic dosages. Consider the use of alternative nonopioid analgesics in these patients.
• Elderly: Elderly patients are at greater risk for serious GI, cardiovascular, renal adverse events, and/or life-threatening respiratory depression; use with caution. Consider the use of alternative nonopioid analgesics in these patients.
• Neonates: Neonatal withdrawal syndrome: [US Boxed Warning]: Prolonged maternal use of opioids during pregnancy can cause neonatal withdrawal syndrome in the newborn which may be life-threatening if not recognized and treated according to protocols developed by neonatology experts. If prolonged opioid therapy is required in a pregnant woman, ensure treatment is available and warn patient of risk to the neonate. Signs and symptoms include irritability, hyperactivity and abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea and failure to gain weight. Onset, duration and severity depend on the drug used, duration of use, maternal dose, and rate of drug elimination by the newborn.

Other warnings/precautions:

• Abrupt discontinuation/withdrawal: Abrupt discontinuation in patients who are physically dependent on opioids has been associated with serious withdrawal symptoms, uncontrolled pain, attempts to find other opioids (including illicit), and suicide. Use a collaborative, patient-specific taper schedule that minimizes the risk of withdrawal, considering factors such as current opioid dose, duration of use, type of pain, and physical and psychological factors. Monitor pain control, withdrawal symptoms, mood changes, suicidal ideation, and for use of other substances; provide care as needed. Concurrent use of mixed agonist/antagonist (eg, pentazocine, nalbuphine, butorphanol) or partial agonist (eg, buprenorphine) analgesics may also precipitate withdrawal symptoms and/or reduced analgesic efficacy in patients following prolonged therapy with mu opioid agonists.
• Abuse/misuse/diversion: [US Boxed Warning]: Oxycodone/ibuprofen exposes patients and other users to the risks of opioid addiction, abuse, and misuse, potentially leading to overdose and death. Assess each patient's risk prior to prescribing; monitor all patients regularly for development of these behaviors or conditions. Use with caution in patients with a history of drug abuse or acute alcoholism; potential for drug dependency exists. Other factors associated with increased risk for misuse include younger age, concomitant depression (major), and psychotropic medication use.
• Accidental exposure: [US Boxed Warning]: Accidental ingestion of even one oxycodone/ibuprofen dose, especially in children, can result in a fatal overdose of oxycodone.
• REMS program: [US Boxed Warning]: To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse, and misuse, a REMS is required. Drug companies with approved opioid analgesic products must make REMS-compliant education programs available to health care providers. Health care providers are encouraged to complete a REMS-compliant education program; counsel patients and/or their caregivers, with every prescription, on safe use, serious risks, storage, and disposal of these products; emphasize to patients and their caregivers the importance of reading the Medication Guide every time it is provided by their pharmacist; and consider other tools to improve patient, household, and community safety.
• Surgical/dental procedures: Withhold NSAIDs for at least 4 to 6 half-lives prior to surgical or dental procedures.
