oxycodone hydrochloride capsule
FULL PRESCRIBING INFORMATION
1 INDICATIONS AND USAGE
Oxycodone hydrochloride capsule is an opioid analgesic, indicated for the management of moderate to severe acute and chronic pain where use of an opioid analgesic is appropriate.
2 DOSAGE AND ADMINISTRATION
Selection of patients for treatment with oxycodone hydrochloride should be governed by the same principles that apply to the use of similar opioid analgesics. Individualize treatment in every case, using non-opioid analgesics, opioids on an as needed basis and/or combination products, and chronic opioid therapy in a progressive plan of pain management such as outlined by the World Health Organization, the Agency for Healthcare Research and Quality, and the American Pain Society.
2.1 Individualization of DosageAs with any opioid drug product, adjust the dosing regimen for each patient individually, taking into account the patient's prior analgesic treatment experience. In the selection of the initial dose of oxycodone hydrochloride, give attention to the following:
The following dosing recommendations, therefore, can only be considered
suggested approaches to what is actually a series of clinical decisions over time
in the management of the pain of each individual patient.
Continual re-evaluation of the patient receiving oxycodone hydrochloride is important, with special attention to the maintenance of pain control and the relative incidence of side effects associated with therapy. During chronic therapy, especially for non-cancer-related pain, periodically re-assess the continued need for the use of opioid analgesics.
During periods of changing analgesic requirements, including initial titration, frequent contact is recommended between physician, other members of the healthcare team, the patient, and the caregiver/family.
2.2 Initiation of Therapy in Opioid-Naive PatientsStart patients who have not been receiving opioid analgesics on oxycodone hydrochloride in the following dosing range using Oxycodone Hydrochloride Capsules, 5 mg strength:
Oxycodone Hydrochloride Capsules: 5 to 15 mg every 4 to 6 hours as needed for pain.
Titrate the dose based upon the individual patient's response to their initial dose of oxycodone hydrochloride. Adjust the dose to an acceptable level of analgesia taking into account the improvement in pain intensity and the tolerability of the oxycodone by the patient.
2.3 Conversion to Oral Oxycodone HydrochlorideThere is inter-patient variability in the potency of opioid drugs and opioid formulations. Therefore, a conservative approach is advised when determining the total daily dose of oxycodone hydrochloride. It is better to underestimate a patient's 24-hour oral oxycodone hydrochloride dose and make available rescue medication than to overestimate the 24-hour oral oxycodone hydrochloride dose and manage an adverse experience of overdose.
Consider the following general points regarding opioid conversions.
Conversion From other Non-Oxycodone Opioids to Oral Oxycodone Hydrochloride.
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. Physicians and other healthcare professionals are advised to refer to published relative potency information, keeping in mind that conversion ratios are only approximate.
Conversion From Controlled-Release Oral Oxycodone to Oral Oxycodone Hydrochloride.
The relative bioavailability of Oxycodone Hydrochloride Capsule compared to controlled-release oxycodone is unknown. The extended duration of release of oxycodone hydrochloride from controlled-release tablets results in reduced maximum and increased minimum plasma oxycodone hydrochloride concentrations than with shorter acting oxycodone hydrochloride products. Conversion from controlled-release tablets could lead to excessive sedation at peak serum levels. Therefore, dose adjustment with close observation is necessary.
Conversion From Oral Oxycodone Hydrochloride to Controlled-Release Oral Oxycodone.
The relative bioavailability of Oxycodone Hydrochloride Capsules compared to controlled-release oxycodone is unknown, so conversion to controlled-release tablets must be accompanied by close observation for signs of excessive sedation.
2.4 Maintenance of TherapyContinual re-evaluation of the patient receiving oxycodone hydrochloride is important, with special attention to the maintenance of pain management and the relative incidence of side effects associated with therapy. If the level of pain increases, effort should be made to identify the source of increased pain, while adjusting the dose as described above to decrease the level of pain. During chronic therapy, especially for non-cancer-related pain (or pain associated with other terminal illnesses), periodically reassess the continued need for the use of opioid analgesics.
3 DOSAGE FORMS AND STRENGTHS
Each oxycodone hydrochloride capsule has an opaque yellow cap imprinted in black ink with "LV" and an opaque white body imprinted in black ink with "901" containing 5 mg of oxycodone hydrochloride, USP.
Oxycodone hydrochloride is contraindicated in patients with respiratory depression in the absence of resuscitative equipment.
Oxycodone hydrochloride is contraindicated in any patient who has or is suspected of having paralytic ileus.
Oxycodone hydrochloride is contraindicated in patients with acute or severe bronchial asthma or hypercarbia.
Oxycodone hydrochloride is contraindicated in patients with known hypersensitivity to oxycodone, oxycodone salts, or any components of the product.
5 WARNINGS AND PRECAUTIONS
5.1 Respiratory DepressionRespiratory depression is the primary risk of oxycodone hydrochloride. Respiratory depression occurs more frequently in elderly or debilitated patients and in those suffering from conditions accompanied by hypoxia, hypercapnia, or upper airway obstruction, in whom even moderate therapeutic doses may significantly decrease pulmonary ventilation.
Use oxycodone hydrochloride with extreme caution in patients with chronic obstructive pulmonary disease or cor pulmonale and in patients having a substantially decreased respiratory reserve (e.g., severe kyphoscoliosis), hypoxia, hypercapnia, or preexisting respiratory depression. In such patients, even usual therapeutic doses of oxycodone hydrochloride may increase airway resistance and decrease respiratory drive to the point of apnea. Consider alternative non-opioid analgesics, and use oxycodone hydrochloride only under careful medical supervision at the lowest effective dose in such patients.
5.2 Misuse, Abuse and Diversion of OpioidsOxycodone hydrochloride is an opioid agonist and a Schedule II controlled substance. Such drugs are sought by drug abusers and people with addiction disorders. Diversion of Schedule II products is an act subject to criminal penalty.
Oxycodone hydrochloride can be abused in a manner similar to other opioid agonists, legal or illicit. This should be considered when prescribing or dispensing oxycodone hydrochloride in situations where the physician or pharmacist is concerned about an increased risk of misuse, abuse, or diversion.
Oxycodone hydrochloride may be abused by crushing, chewing, snorting or injecting the product. These practices pose a significant risk to the abuser that could result in overdose and death. [See DRUG ABUSE AND DEPENDENCE (9)]
Concerns about abuse, addiction, and diversion should not prevent the proper management of pain. Healthcare professionals should contact their State Professional Licensing Board or State Controlled Substances Authority for information on how to prevent and detect abuse or diversion of this product.
5.3 Interactions with Alcohol and Drugs of AbuseOxycodone hydrochloride may be expected to have additive effects when used in conjunction with alcohol, other opioids, or illicit drugs that cause central nervous system depression because respiratory depression, hypotension, profound sedation, coma or death may result.
5.4 Use In Head Injury and Increased Intracranial PressureIn the presence of head injury, intracranial lesions or a preexisting increase in intracranial pressure, the possible respiratory depressant effects of oxycodone hydrochloride and its potential to elevate cerebrospinal fluid pressure (resulting from vasodilation following CO2 retention) may be markedly exaggerated. Furthermore, oxycodone hydrochloride can produce effects on pupillary response and consciousness, which may obscure neurologic signs of further increases in intracranial pressure in patients with head injuries.
5.5 Hypotensive EffectOxycodone hydrochloride may cause severe hypotension in an individual whose ability to maintain blood pressure has already been compromised by a depleted blood volume or concurrent administration of drugs such as phenothiazines or general anesthetics. Oxycodone hydrochloride may produce orthostatic hypotension and syncope in ambulatory patients.
Administer oxycodone hydrochloride with caution to patients in circulatory shock, as vasodilation produced by the drug may further reduce cardiac output and blood pressure.
5.6 Gastrointestinal EffectsDo not administer oxycodone hydrochloride to patients with gastrointestinal obstruction, especially paralytic ileus because oxycodone hydrochloride diminishes propulsive peristaltic waves in the gastrointestinal tract and may prolong the obstruction.
The administration of oxycodone hydrochloride may obscure the diagnosis or clinical course in patients with acute abdominal condition.
5.7 Use In Pancreatic/Biliary Tract DiseaseUse oxycodone hydrochloride with caution in patients with biliary tract disease, including acute pancreatitis, as oxycodone hydrochloride may cause spasm of the sphincter of Oddi and diminish biliary and pancreatic secretions.
5.8 Special Risk GroupsUse oxycodone hydrochloride with caution and in reduced dosages in patients with severe renal or hepatic impairment, Addison's disease, hypothyroidism, prostatic hypertrophy, or urethral stricture, and in elderly or debilitated patients. [See USE IN SPECIFIC POPULATIONS (8.5)]
Exercise caution in the administration of oxycodone hydrochloride to patients with CNS depression, toxic psychosis, acute alcoholism and delirium tremens. All opioids may aggravate convulsions in patients with convulsive disorders, and all opioids may induce or aggravate seizures in some clinical settings.
Keep Oxycodone Hydrochloride capsules out of the reach of children. In case of accidental ingestion, seek emergency medical help immediately.
5.9 Driving and Operating MachineryCaution patients that oxycodone hydrochloride could impair the mental and/or physical abilities needed to perform potentially hazardous activities such as driving a car or operating machinery. Caution patients about the potential combined effects of oxycodone hydrochloride with other CNS depressants, including other opioids, phenothiazines, sedative/hypnotics and alcohol. [See DRUG INTERACTIONS (7)]
5.10 Cytochrome P450 3A4 Inhibitors and InducersSince the CYP3A4 isoenzyme plays a major role in the metabolism of oxycodone, drugs that alter CYP3A4 activity may cause changes in clearance of oxycodone which could lead to changes in oxycodone plasma concentrations. The expected clinical results with CYP3A4 inhibitors would be an increase in oxycodone plasma concentrations and possibly increased or prolonged opioid effects. The expected clinical results with CYP3A4 inducers would be a decrease in oxycodone plasma concentrations, lack of efficacy or, possibly, development of an abstinence syndrome in a patient who had developed physical dependence to oxycodone.
If co-administration is necessary, caution is advised when initiating oxycodone 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) and Clinical Pharmacology (12.3)]
6 ADVERSE REACTIONS
Serious adverse reactions that may be associated with oxycodone therapy in clinical use are those observed with other opioid analgesics and include: respiratory depression, respiratory arrest, circulatory depression, cardiac arrest, hypotension, and/or shock.
The common adverse events seen on initiation of therapy with oxycodone are also typical opioid side effects. These events are dose dependent, and their frequency depends on the clinical setting, the patient's level of opioid tolerance, and host factors specific to the individual. They should be expected and managed as a part of opioid therapy. The most frequent of adverse events include nausea, constipation, vomiting, headache, and pruritus.
The frequency of adverse events during initiation of opioid therapy may be minimized by careful individualization of starting dosage, slow titration and the avoidance of large rapid swings in plasma concentration of the opioid. Many of these common adverse events may abate as therapy is continued and some degree of tolerance is developed, but others may be expected to remain throughout therapy.
In all patients for whom dosing information was available (n=191) from the open-label and double-blind studies involving immediate-release oxycodone, the following adverse events were recorded in oxycodone treated patients with an incidence greater than or equal to 3%. In descending order of frequency they were: nausea, constipation, vomiting, headache, pruritus, insomnia, dizziness, asthenia, and somnolence.
The following adverse experiences occurred in less than 3% of patients involved in clinical trials with oxycodone:

7 DRUG INTERACTIONS
7.1 CNS DepressantsOther central nervous system (CNS) depressants including sedatives, hypnotics, general anesthetics, antiemetics, phenothiazines, or other tranquilizers or alcohol increases the risk of respiratory depression, hypotension, profound sedation, or coma. Use oxycodone hydrochloride with caution and in reduced dosages in patients taking these agents.
7.2 Muscle RelaxantsOxycodone hydrochloride may enhance the neuromuscular blocking action of skeletal muscle relaxants and produce an increased degree of respiratory depression.
7.3 Mixed Agonist/Antagonist Opioid AnalgesicsDo not administer mixed agonist/antagonist analgesics (i.e., pentazocine, nalbuphine, butorphanol and buprenorphine) to patients who have received or are receiving a course of therapy with a pure opioid agonist analgesic such as oxycodone hydrochloride. In these patients, mixed agonist/antagonist analgesics may reduce the analgesic effect and/or may precipitate withdrawal symptoms.
7.4 Agents Affecting Cytochrome P450 Enzymes
7.5 Monoamine Oxidase Inhibitors (MAOIs)
No specific interaction between oxycodone and monoamine oxidase inhibitors has been observed, but caution in the use of any opioid in patients taking this class of drugs is appropriate.
8 USE IN SPECIFIC POPULATIONS
8.1 PregnancyPregnancy Category B: There are no adequate and well-controlled studies of oxycodone use during pregnancy. Based on limited human data in the literature, oxycodone does not appear to increase the risk of congenital malformations. Because animal reproduction studies are not always predictive of human response, oxycodone should be used during pregnancy only if clearly needed.
8.2 Labor and DeliveryOpioids cross the placenta and may produce respiratory depression and psycho-physiologic effects in neonates. Oxycodone hydrochloride is not recommended for use in women during and immediately prior to labor. Occasionally, opioid analgesics may prolong labor through actions which temporarily reduce the strength, duration and frequency of uterine contractions. However this effect is not consistent and may be offset by an increased rate of cervical dilatation, which tends to shorten labor. Closely observe neonates whose mothers received opioid analgesics during labor for signs of respiratory depression. Have a specific opioid antagonist, such as naloxone or nalmefene, available for reversal of opioid-induced respiratory depression in the neonate.
8.3 Nursing MothersLow levels of oxycodone have been detected in maternal milk. The amount of oxycodone hydrochloride delivered to the infant depends on the plasma concentration of the mother, the amount of milk ingested by the infant, and the extent of first-pass metabolism. Because of the potential for serious adverse reactions in nursing infants from oxycodone hydrochloride including respiratory depression, sedation and possibly withdrawal symptoms, upon cessation of oxycodone hydrochloride administration to the mother, decide whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
8.4 Pediatric UseThe safety and effectiveness and the pharmacokinetics of Oxycodone Hydrochloride Capsule in pediatric patients below the age of 18 have not been established.
8.5 Geriatric UseElderly patients (aged 65 years or older) may have increased sensitivity to oxycodone hydrochloride. In general, use caution when selecting a dose for an elderly patient, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy.
8.6 Hepatic ImpairmentSince oxycodone is extensively metabolized, its clearance may be decreased in patients with hepatic impairment. Follow a conservative approach to dose initiation in patients with hepatic impairment, monitor patients closely and adjust the dose based on clinical response.
8.7 Renal ImpairmentInformation from oxycodone tablets indicate 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. Use a conservative approach to dose initiation in patients with renal impairment, monitor patients closely and adjust the dose based on clinical response.
9 DRUG ABUSE AND DEPENDENCE
9.1 Controlled SubstanceOxycodone hydrochloride is a mu-agonist opioid and is a Schedule II controlled substance. Oxycodone hydrochloride, like other opioids used in analgesia, can be abused and is subject to criminal diversion.
9.2 AbuseDrug addiction is characterized by compulsive use, use for non-medical purposes, and continued use despite harm or risk of harm. Drug addiction is a treatable disease, utilizing a multi-disciplinary approach, but relapse is common.
"Drug-seeking" behavior is very common in addicts and drug abusers. 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 physician(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. Physicians should be aware that addiction may not be accompanied by concurrent tolerance and symptoms of physical dependence. The converse is also true. In addition, abuse of opioids can occur in the absence of true addiction and is characterized by misuse for nonmedical purposes, often in combination with other psychoactive substances. Careful record-keeping of prescribing information, including quantity, frequency, and renewal requests is strongly advised.
Oxycodone hydrochloride is intended for oral use only. Abuse of oxycodone hydrochloride poses a risk of overdose and death. The risk is increased with concurrent abuse of alcohol and other substances. Parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and HIV.
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.
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 (8.2)]
9.3 DependenceTolerance 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). Physical dependence is manifested by withdrawal symptoms after abrupt discontinuation of a drug or upon administration of an antagonist. Physical dependence and tolerance are not unusual during chronic opioid therapy.
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 general, taper opioids rather than abruptly discontinue. [See DOSAGE AND ADMINISTRATION (2.5)]
10.1 SymptomsAcute overdosage with oxycodone hydrochloride is manifested by respiratory depression (a decrease in respiratory rate and/or tidal volume, Cheyne-Stokes respiration, cyanosis), extreme somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and, in some cases, pulmonary edema, bradycardia, hypotension, cardiac arrest and death.
Oxycodone hydrochloride may cause 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 origin may produce similar findings). Marked mydriasis rather than miosis may be seen with hypoxia in overdose situations. [See CLINICAL PHARMACOLOGY (12)]
10.2 TreatmentGive primary attention to re-establishment of a patent airway and institution of assisted or controlled ventilation. Employ supportive measures (including oxygen and vasopressors) in the management of circulatory shock and pulmonary edema accompanying overdose as indicated. Cardiac arrest or arrhythmias may require cardiac massage or defibrillation.
The pure opioid antagonists, naloxone or nalmefene, are specific antidotes to respiratory depression resulting from opioid overdose. Since the duration of reversal is expected to be less than the duration of action of oxycodone hydrochloride, carefully monitor the patient until spontaneous respiration is reliably re-established. If the response to opioid antagonists is suboptimal or only brief in nature, administer additional antagonist as directed by the manufacturer of the product.
Do not administer opioid antagonists in the absence of clinically significant respiratory or circulatory depression secondary to oxycodone overdose. Administer such agents cautiously to persons who are known, or suspected to be physically dependent on oxycodone. 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 symptoms experienced will depend on the degree of physical dependence and the dose of the antagonist administered. Reserve use of an opioid antagonist for cases where such treatment is clearly needed. If it is necessary to treat serious respiratory depression in the physically dependent patient, initiate administration of the antagonist with care and titrate with smaller than usual doses.
Oxycodone hydrochloride is a white, odorless crystalline powder derived from the opium alkaloid, thebaine. It is soluble in water and slightly soluble in alcohol.
Chemically, oxycodone hydrochloride is (5R,9R,13S,14S)-4, 5α-epoxy-14-hydroxy-3-methoxy-17-methylmorphinan-6-one, hydrochloride (salt) with a molecular mass of 351.82.
Each hard gelatin capsule contains 5 mg of oxycodone hydrochloride, USP and the following inactive ingredients: colloidal silicon dioxide, FD&C Yellow #6, gelatin, lactose anhydrous, magnesium stearate, microcrystalline cellulose, pregelatinized starch, sodium lauryl sulfate, sodium starch glycolate, titanium dioxide and yellow iron oxide.
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of ActionOxycodone hydrochloride, a pure opioid agonist, is relatively selective for the mu receptor, although it can interact with other opioid receptors at higher doses. In addition to analgesia, the widely diverse effects of oxycodone hydrochloride include drowsiness, changes in mood, respiratory depression, decreased gastrointestinal motility, nausea, vomiting, and alterations of the endocrine and autonomic nervous system.
Effects on the
Central Nervous System (CNS)
Effects on the Gastrointestinal Tract And
Other Smooth Muscle
Effects on the Cardiovascular
12.3 PharmacokineticsThe activity of oxycodone hydrochloride capsules is primarily due to the parent drug oxycodone.
The oral bioavailability of oxycodone is 60% to 87%. Oxycodone is extensively metabolized and eliminated primarily in the urine as both conjugated and unconjugated parent and its metabolites. The apparent elimination half-life of oxycodone is approximately 4 hours.
Gender: Information obtained from oxycodone tablets support the lack of gender effect on the pharmacokinetics of oxycodone.
Renal Impairment: Information obtained from oxycodone tablets indicate that patients with renal impairment (defined as creatinine clearance <60 mL/min) had higher plasma concentrations of oxycodone than subjects with normal renal function.
Hepatic Impairment: Since oxycodone is extensively metabolized, its clearance may decrease in patients with hepatic impairment.
