Oxycodone Hcl Drug Information

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 treatment with oxycodone hydrochloride. 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). 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.

Consider prescribing naloxone if the patient has household members (including children) or other close contacts at risk for accidental ingestion or overdose.

Initial Dosage

Although it is not possible to list every condition that is important to the selection of the initial dose of Oxycodone Hydrochloride Tablets, attention must be given to: 1. the daily dose, potency and characteristics of a full agonist or mixed agonist/antagonist the patient has been taking previously. 2. the reliability of the relative potency estimate to calculate the dose of oxycodone HCl needed. 3. the degree of opioid tolerance. 4. the general condition and medical status of the patient, including the patient’s weight and age. 5. the balance between pain management and adverse reactions. 6. the type and severity of the patient’s pain. 7. risk factors for abuse or addiction, including a prior history of abuse or addiction. Use of Oxycodone Hydrochloride Tablets as the First Opioid Analgesic Initiate treatment with oxycodone hydrochloride in a dosing range of 5 to 15 mg every 4 to 6 hours as needed for pain, and at the lowest dose necessary to achieve adequate analgesia. Titrate the dose based upon the individual patient’s response to their initial dose of oxycodone hydrochloride.

Conversion from Other Opioids to Oxycodone Hydrochloride There is inter-patient variability in the potency of opioid drugs and opioid formulations. Therefore, a conservative approach is advised when determining the total daily dosage of oxycodone hydrochloride. It is safer to underestimate a patient’s 24-hour Oxycodone Hydrochloride Tablets dosage than to overestimate the 24-hour oxycodone hydrochloride dosage and manage an adverse reaction due to overdose.

If a patient has been receiving opioid-containing medications prior to taking oxycodone hydrochloride, the potency of the prior opioid relative to oxycodone should be factored into the selection of the total daily dose (TDD) of oxycodone. In converting patients from other opioids to oxycodone hydrochloride close observation and adjustment of dosage based upon the patient’s response to oxycodone hydrochloride is imperative. Administration of supplemental analgesia for breakthrough or incident pain and titration of the total daily dose of oxycodone hydrochloride may be necessary, especially in patients who have disease states that are changing rapidly.

Conversion From Fixed-Ratio Opioid/Acetaminophen, Opioid/Aspirin, or Opioid/Nonsteroidal Combination Drugs When converting patients from fixed ratio opioid/non-opioid drug regimens a decision should be made whether or not to continue the non-opioid analgesic. If a decision is made to discontinue the use of non-opioid analgesic, it may be necessary to titrate the dose of oxycodone hydrochloride in response to the level of analgesia and adverse effects afforded by the dosing regimen. If the non-opioid regimen is continued as a separate single entity agent, the starting dose oxycodone hydrochloride should be based upon the most recent dose of opioid as a baseline for further titration of oxycodone.

Incremental increases should be gauged according to side effects to an acceptable level of analgesia. Conversion from Oxycodone Hydrochloride Tablets to Extended-Release Oxycodone The relative bioavailability of oxycodone hydrochloride tablets compared to extended-release oxycodone is unknown, so conversion to extended-release oxycodone may lead to increased risk of excessive sedation and respiratory depression.

Titration and Maintenance of Therapy Individually titrate oxycodone hydrochloride to a dose

that provides adequate analgesia and minimizes adverse reactions. Continually reevaluate patients receiving oxycodone hydrochloride to assess the maintenance of pain control, sign and symptoms of opioid withdrawal, and other adverse reactions, as well as reassess for the development of addiction, abuse, or misuse. Frequent communication is important among the prescriber, other members of the healthcare team, the patient, and the caregiver/family during periods of changing analgesic requirements, including initial titration.

If the level of pain increases after dosage stabilization, attempt to identify the source of increased pain before increasing the oxycodone hydrochloride dosage. If after increasing the dosage, unacceptable opioid-related adverse reactions are observed (including an increase in pain after a dosage increase), consider reducing the dosage. Adjust the dosage to obtain an appropriate balance between management of pain and opioid-related adverse reactions.

Safe Reduction or Discontinuation of Oxycodone Hydrochloride Tablets Do not abruptly discontinue

oxycodone hydrochloride in patients who may be physically dependent on opioids. Rapid discontinuation of opioid analgesics in patients who are physically dependent on opioids has resulted in serious withdrawal symptoms, uncontrolled pain, and suicide. Rapid discontinuation has also been associated with attempts to find other sources of opioid analgesics, which may be confused with drug-seeking for abuse.

Patients may also attempt to treat their pain or withdrawal symptoms with illicit opioids, such as heroin, and other substances. When a decision has been made to decrease the dose or discontinue therapy in an opioid-dependent patient taking oxycodone hydrochloride, there are a variety of factors that should be considered, including the total daily dose of opioid (including oxycodone hydrochloride) the patient has been taking, the duration of treatment, the type of pain being treated, and the physical and psychological attributes of the patient. It is important to ensure ongoing care of the patient and to agree on an appropriate tapering schedule and follow-up plan so that patient and provider goals and expectations are clear and realistic.

When opioid analgesics are being discontinued due to a suspected substance use disorder, evaluate and treat the patient, or refer for evaluation and treatment of the substance use disorder. Treatment should include evidence-based approaches, such as medication assisted treatment of opioid use disorder. Complex patients with comorbid pain and substance use disorders may benefit from referral to a specialist.

There are no standard opioid tapering schedules that are suitable for all patients. Good clinical practice dictates a patient-specific plan to taper the dose of the opioid gradually. For patients on oxycodone hydrochloride who are physically opioid-dependent, initiate the taper by a small enough increment (e.g., no greater than 10% to 25% of the total daily dose) to avoid withdrawal symptoms, and proceed with dose-lowering at an interval of every 2 to 4 weeks.

Patients who have been taking opioids for briefer periods of time may tolerate a more rapid taper. It may be necessary to provide the patient with lower dosage strengths to accomplish a successful taper. Reassess the patient frequently to manage pain and withdrawal symptoms, should they emerge.

Common withdrawal symptoms include restlessness, lacrimation, rhinorrhea, yawning, perspiration, chills, myalgia, and mydriasis. Other signs and symptoms also may develop, including irritability, anxiety, backache, joint pain, weakness, abdominal cramps, insomnia, nausea, anorexia, vomiting, diarrhea, or increased blood pressure, respiratory rate, or heart rate. If withdrawal symptoms arise, it may be necessary to pause the taper for a period of time or raise the dose of the opioid analgesic to the previous dose, and then proceed with a slower taper.

In addition, evaluate patients for any changes in mood, emergence of suicidal thoughts, or use of other substances. When managing patients taking opioid analgesics, particularly those who have been treated for an extended period of time, and/or with high doses for chronic pain, ensure that a multimodal approach to pain management, including mental health support (if needed), is in place prior to initiating an opioid analgesic taper. A multimodal approach to pain management may optimize the treatment of chronic pain, as well as assist with the successful tapering of the opioid analgesic.

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Oxycodone hydrochloride have been evaluated in open label clinical trials in patients with cancer and nonmalignant pain. Oxycodone hydrochloride are associated with adverse experiences similar to those seen with other opioids.

Serious adverse reactions associated with oxycodone hydrochloride use included: respiratory depression, respiratory arrest, circulatory depression, cardiac arrest, hypotension, and/or shock. The common adverse reactions seen on initiation of therapy with oxycodone hydrochloride are dose-related and are typical opioid-related adverse reactions. The most frequent of these included nausea, constipation, vomiting, headache, pruritus, insomnia, dizziness, asthenia, and somnolence.

The frequency of these reactions depended on several factors, including clinical setting, the patient’s level of opioid tolerance, and host factors specific to the individual. In all patients for whom dosing information was available (n=191) from the open-label and double-blind studies involving oxycodone hydrochloride, the following adverse events were recorded in oxycodone hydrochloride treated patients with an incidence ≥ 3%. In descending order of frequency, they were: nausea, constipation, vomiting, headache, pruritus, insomnia, dizziness, asthenia, and somnolence. Other less frequently observed adverse reactions from opioid analgesics, including oxycodone hydrochloride included: Blood and lymphatic system disorders:anemia, leukopenia Cardiac disorders:cardiac failure, palpitation, tachycardia Gastrointestinal disorders: abdominal pain, dry mouth, diarrhea, dyspepsia, dysphagia, glossitis, nausea, vomiting.

General disorders and administration site conditions:chills, edema, edema peripheral, pain, pyrexia Immune system disorders:hypersensitivity Infections and infestations:bronchitis, gingivitis, infection, pharyngitis, rhinitis, sepsis, sinusitis, urinary tract infection Injury, poisoning and procedural complications:injury Metabolism and nutrition disorders:decreased appetite, gout, hyperglycemia Musculoskeletal and connective tissue disorders:arthralgia, arthritis, back pain, bone pain, myalgia, neck pain, pathological fracture Nervous system disorders:hypertonia, hypoesthesia, migraine, neuralgia, tremor, vasodilation Psychiatric disorders:agitation, anxiety, confusional state, nervousness, personality disorder Respiratory, thoracic and mediastinal disorders:cough, dyspnea, epistaxis, laryngospasm, lung disorder Skin and subcutaneous tissue disorders:photosensitivity reaction, rash, hyperhidrosis, urticaria Vascular disorders:thrombophlebitis, hemorrhage, hypotension, vasodilatation

Postmarketing Experience

The following adverse reactions have been identified during post approval use of oxycodone. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. General disorders and administrative site disorders:drug withdrawal syndrome neonatal Respiratory, thoracic and mediastinal disorders:pharyngeal edema Serotonin syndrome:Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during concomitant use of opioids with serotonergic drugs.

Adrenal insufficiency:Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. Anaphylaxis:Anaphylactic reaction has been reported with ingredients contained in oxycodone hydrochloride. Androgen deficiency:Cases of androgen deficiency have occurred with use of opioids for an extended period of time.

Hyperalgesia and Allodynia: Cases of hyperalgesia and allodynia have been reported with opioid therapy of any duration. Hypoglycemia: Cases of hypoglycemia have been reported in patients taking opioids. Most reports were in patients with at least one predisposing risk factor (e.g., diabetes).

Table 1 includes clinically significant drug interactions with oxycodone hydrochloride. Table 1: Clinically Significant Drug Interactions with Oxycodone Hydrochloride Tablets Inhibitors of CYP3A4 and CYP2D6 Clinical Impact: The concomitant use of oxycodone hydrochloride and CYP3A4 inhibitors can increase the plasma concentration of oxycodone, resulting in increased or prolonged opioid effects. These effects could be more pronounced with concomitant use of oxycodone hydrochloride and CYP2D6 and CYP3A4 inhibitors, particularly when an inhibitor is added after a stable dose of oxycodone hydrochloride is achieved.

After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, the oxycodone plasma concentration will decrease, resulting in decreased opioid efficacy or a withdrawal syndrome in patients who had developed physical dependence to oxycodone. Intervention: If concomitant use is necessary, consider dosage reduction of oxycodone hydrochloride until stable drug effects are achieved. Evaluate patients at frequent intervals for respiratory depression and sedation.

If a CYP3A4 inhibitor is discontinued, consider increasing the oxycodone hydrochloride dosage until stable drug effects are achieved. Evaluate for signs of opioid withdrawal. Examples: Macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g., ketoconazole), protease inhibitors (e.g., ritonavir). CYP3A4 Inducers Clinical Impact: The concomitant use of oxycodone hydrochloride and CYP3A4inducers 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.

After stopping a CYP3A4 inducer, as the effects of the inducer decline, the oxycodone plasma concentration will increase, which could increase or prolong both the therapeutic effects and adverse reactions, and may cause serious respiratory depression. Intervention: If concomitant use is necessary, consider increasing the oxycodone hydrochloride dosage until stable drug effects are achieved. Evaluate patients for signs of opioid withdrawal.

If a CYP3A4 inducer is discontinued, consider oxycodone hydrochloride dosage reduction and evaluate patients at frequent intervals for signs of respiratory depression and sedation. Examples: Rifampin, carbamazepine, phenytoin Benzodiazepines and Other Central Nervous System (CNS) Depressants Clinical Impact: Due to additive pharmacologic effect, the concomitant use of benzodiazepines or other CNS depressants, including alcohol, can increases the risk of hypotension, respiratory depression, profound sedation, coma, and death. Intervention: Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate.

Limit dosages and durations to the minimum required. 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. Examples: Benzodiazepines and other sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids, alcohol.

Serotonergic Drugs Clinical Impact: The concomitant use of opioids with other drugs that affect the serotonergic neurotransmitter system has resulted in serotonin syndrome. Intervention: If concomitant use is warranted, frequently evaluate the patient, particularly during treatment initiation and dose adjustment. Discontinue oxycodone hydrochloride if serotonin syndrome is suspected.

Examples: Selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), triptans, 5-HT3 receptor antagonists, drugs that affect the serotonin neurotransmitter system (e.g., mirtazapine, trazodone, tramadol),certain muscle relaxants (i.e., cyclobenzaprine, metaxalone),monoamine oxidase (MAO) inhibitors (those intended to treat psychiatric disorders and also others, such as linezolid and intravenous methylene blue). Monoamine Oxidase Inhibitors (MAOIs) Clinical Impact: MAOI interactions with opioids may manifest as serotonin syndrome or opioid toxicity (e.g., respiratory depression, coma). Intervention: The use of oxycodone hydrochloride is not recommended for patients taking MAOIs or within 14 days of stopping such treatment. If urgent use of an opioid is necessary, use test doses and frequent titration of small doses to treat pain while closely monitoring blood pressure and signs and symptoms of CNS and respiratory depression. Examples: phenelzine, tranylcypromine, linezolid Mixed Agonist/Antagonist Opioid Analgesics Clinical Impact: May reduce the analgesic effect of oxycodone hydrochloride and/or may precipitate withdrawal symptoms.

Intervention: Avoid concomitant use Examples Butorphanol, nalbuphine, pentazocine, buprenorphine Muscle Relaxants Clinical Impact: Oxycodone may enhance the neuromuscular blocking action of skeletal muscle relaxants and produce an increased degree of respiratory depression. Intervention: Because respiratory depression may be greater than otherwise expected, decrease the dosage of oxycodone hydrochloride and/or the muscle relaxant as necessary. Due to the risk of respiratory depression with concomitant use of skeletal muscle relaxants and opioids, consider prescribing naloxone for the emergency treatment of opioid overdose.

Diuretics Clinical Impact: Opioids can reduce the efficacy of diuretics by inducing the release of antidiuretic hormone. Intervention: Evaluate patients for signs of dismissed diuresis and/or effects on blood pressure and increase the dosage of the diuretic as needed. Anticholinergic Drugs Clinical Impact: The concomitant risk of anticholinergic drugs may result in increased risk of urinary retention and/or severe constipation, which may lead to paralytic ileus.

Intervention: Evaluate patients for signs of urinary retention or reduced gastric motility when oxycodone hydrochloride are used concurrently with anticholinergic drugs.

Oxycodone hydrochloride tablets are 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

Clinical Presentation Acute overdose with oxycodone can be manifested by respiratory depression, somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and in some cases, pulmonary edema, bradycardia, hypotension, hypoglycemia, partial or complete airway obstruction, atypical snoring, and death. Marked mydriasis rather than miosis may be seen with hypoxia in overdose situations. Treatment of Overdose In case of overdose, priorities are the re-establishment of a patent and protected airway and institution of assisted or controlled ventilation, if needed.

Employ other supportive measures (including oxygen and vasopressors) in the management of circulatory shock and pulmonary edema as indicated. Cardiac arrest or arrhythmias will require advanced life-support measures. Opioid antagonists, such as naloxone, are specific antidotes to respiratory depression resulting from opioid overdose.

For clinically significant respiratory or circulatory depression secondary to opioid overdose, administer an opioid antagonist. Because the duration of opioid reversal is expected to be less than the duration of action of oxycodone in oxycodone hydrochloride, carefully monitor the patient until spontaneous respiration is reliably reestablished. If the response to an opioid antagonist is suboptimal or only brief in nature, administer additional antagonist as directed by the product’s prescribing information.

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