CONTROLLED SUBSTANCE SECTION.

9.1 Controlled Substance. Oxycodone Hydrochloride Oral Solution, USP contains oxycodone, Schedule II controlled substance.

ABUSE SECTION.

9.2 Abuse. Oxycodone Hydrochloride Oral Solution, USP contains oxycodone, substance with high potential for abuse similar to other opioids including fentanyl, hydrocodone, hydromorphone, methadone, morphine, oxymorphone, and tapentadol. Oxycodone Hydrochloride Oral Solution, USP can be abused and is subject to misuse, addiction, and criminal diversion [see Warnings and Precautions (5.2)] All patients treated with opioids require careful monitoring for signs of abuse and addiction, because use of opioid analgesic products carries the risk of addiction even under appropriate medical use.Prescription drug abuse is the intentional non-therapeutic use of prescription drug, even once, for its rewarding psychological or physiological effects.Drug addiction is cluster of behavioral, cognitive, and physiological phenomena that develop after repeated substance use and includes: strong desire to take the drug, difficulties in controlling its use, persisting in its use despite harmful consequences, higher priority given to drug use than to other activities and obligations, increased tolerance, and sometimes physical withdrawal.Drug-seeking behavior is very common in persons with substance use disorders. Drug-seeking tactics include emergency calls or visits near the end of office hours, refusal to undergo appropriate examination, testing, or referral, repeated loss of prescriptions, tampering with prescriptions, and reluctance to provide prior medical records or contact information for other treating health care provider(s). Doctor shopping (visiting multiple prescribers to obtain additional prescriptions) is common among drug abusers and people suffering from untreated addiction. Preoccupation with achieving adequate pain relief can be appropriate behavior in patient with poor pain control.Abuse and addiction are separate and distinct from physical dependence and tolerance. Health care providers should be aware that addiction may not be accompanied by concurrent tolerance and symptoms of physical dependence in all addicts. In addition, abuse of opioids can occur in the absence of true addiction. Oxycodone Hydrochloride Oral Solution, USP, like other opioids, can be diverted for non-medical use into illicit channels of distribution. Careful record-keeping of prescribing information, including quantity, frequency, and renewal requests, as required by state and federal law, is strongly advised. Proper assessment of the patient, proper prescribing practices, periodic re-evaluation of therapy, and proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs.. Risks Specific to Abuse of Oxycodone Hydrochloride Oral SolutionOxycodone Hydrochloride Oral Solution, USP is for oral use only. Abuse of oxycodone poses risk of overdose and death. The risk is increased with concurrent abuse of alcohol and other central nervous system depressants. Parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and HIV.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. CarcinogenesisLong-term studies in animals to evaluate the carcinogenic potential of oxycodone have not been conducted.. MutagenesisOxycodone hydrochloride was genotoxic in an in vitro mouse lymphoma assay in the presence of metabolic activation. There was no evidence of genotoxic potential in an in vitro bacterial reverse mutation assay (Salmonella typhimurium and Escherichia coli) or in an assay for chromosomal aberrations in vivo mouse bone marrow micronucleus assay). Impairment of FertilityStudies in animals to evaluate the potential impact of oxycodone on fertility have not been conducted.

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Oxycodone is full opioid agonist and is relatively selective for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of oxycodone is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with oxycodone. Clinically, dosage is titrated to provide adequate analgesia and may be limited by adverse reactions, including respiratory and CNS depression.The precise mechanism of the analgesic action is unknown. However, specific CNS opioid receptors for endogenous compounds with opioid-like activity have been identified throughout the brain and spinal cord and are thought to play role in the analgesic effects of this drug.. 12.2 Pharmacodynamics. Effects on Central Nervous System (CNS)Oxycodone produces respiratory depression by direct action on brain stem respiratory centers. The respiratory depression involves reduction in the responsiveness of the brain stem respiratory centers to both increases in carbon dioxide tension and to electrical stimulation.Oxycodone causes miosis, even in total darkness. Pinpoint pupils are sign of opioid overdose but are not pathognomonic (e.g., pontine lesions of hemorrhagic or ischemic origins may produce similar findings). Marked mydriasis rather than miosis may be seen due to hypoxia in overdose situations. Effects on the Gastrointestinal Tract and Other Smooth MuscleOxycodone causes reduction in motility associated with an increase in smooth muscle tone in the antrum of the stomach and duodenum. Digestion of food in the small intestine is delayed and propulsive contractions are decreased. Propulsive peristaltic waves in the colon are decreased, while tone may be increased to the point of spasm resulting in constipation. Other-opioid induced effects may include reduction in biliary and pancreatic secretions, spasm of sphincter of Oddi, and transient elevations in serum amylase.. Effects on the Cardiovascular SystemOxycodone produces peripheral vasodilation which may result in orthostatic hypotension or syncope. Manifestations of histamine release and/or peripheral vasodilation may include pruritus, flushing, red eyes and sweating and/or orthostatic hypotension.. Effects on the Endocrine SystemOpioids inhibit the secretion of adrenocorticotropic hormone (ACTH), cortisol, and luteinizing hormone (LH) in humans [see Adverse Reactions (6)]. They also stimulate prolactin, growth hormone (GH) secretion, and pancreatic secretion of insulin and glucagon. Chronic use of opioids may influence the hypothalamic-pituitary-gonadal axis, leading to androgen deficiency that may manifest as low libido, impotence, erectile dysfunction, amenorrhea, or infertility. The causal role of opioids in the clinical syndrome of hypogonadism is unknown because the various medical, physical, lifestyle, and psychological stressors that may influence gonadal hormone levels have not been adequately controlled for in studies conducted to date [see Adverse Reactions (6)]. Effects on the Immune SystemOpioids have been shown to have variety of effects on components of the immune system in in vitro and animal models. The clinical significance of these findings is unknown. Overall, the effects of opioids appear to be modestly immunosuppressive.. Concentration-Efficacy RelationshipsThe minimum effective analgesic concentration will vary widely among patients, especially among patients who have been previously treated with potent agonist opioids. The minimum effective analgesic concentration of oxycodone for any individual patient may increase over time due to an increase in pain, the development of new pain syndrome and/or the development of analgesic tolerance [see Dosage and Administration (2.1, 2.2)]. Concentration-Adverse Reaction RelationshipsThere is relationship between increasing oxycodone plasma concentration and increasing frequency of dose-related opioid adverse reactions such as nausea, vomiting, CNS effects, and respiratory depression. In opioid-tolerant patients, the situation may be altered by the development of tolerance to opioid-related adverse reactions [see Dosage and Administration (2.1, 2.2, 2.3)]. 12.3 Pharmacokinetics. The activity of Oxycodone Hydrochloride Oral Solution, USP is primarily due to the parent drug oxycodone.. AbsorptionThe oral bioavailability of oxycodone is 60 to 87%. This high oral bioavailability (compared to other oral opioids) is due to lower pre-systemic and/or first-pass metabolism of oxycodone.. Food EffectPresence of food may slightly delay the rate (C max and max) and enhance the extent of absorption (AUC) of oxycodone from Oxycodone Hydrochloride Oral Solution, USP. Overall, food is not expected to have clinically significant impact on the absorption of Oxycodone Hydrochloride Oral Solution, USP. DistributionFollowing intravenous administration, the volume of distribution (Vss) for oxycodone was 2.6 L/kg. Plasma protein binding of oxycodone at 37C and pH of 7.4 was about 45%. Oxycodone has been found in breast milk [see Use in Specific Populations (8.2) ]. Elimination. MetabolismOxycodone hydrochloride is extensively metabolized to noroxycodone, oxymorphone, noroxymorphone, which are subsequently glucuronidated. CYP3A4 mediated N-demethylation to noroxycodone is the primary metabolic pathway of oxycodone with less contribution from CYP2D6 mediated O-demethylation to oxymorphone. Therefore, the formation of these and related metabolites can, in theory, be affected by other drugs. The major circulating metabolite is noroxycodone with an AUC ratio of 0.6 relative to that of oxycodone. Noroxycodone is reported to be considerably weaker analgesic than oxycodone. Oxymorphone, although possessing analgesic activity, is present in the plasma only in low concentrations. The correlation between oxymorphone concentrations and opioid effects was much less than that seen with oxycodone plasma concentrations. The analgesic activity profile of other metabolites is not known.. ExcretionOxycodone and its metabolites are excreted primarily via the kidney. The amounts measured in the urine have been reported as follows: free oxycodone up to 19%; conjugated oxycodone up to 50%; free oxymorphone 0%; conjugated oxymorphone <= 14%; both free and conjugated noroxycodone have been found in the urine but not quantified. The total plasma clearance was 0.8 L/min for adults. Apparent elimination half-life of oxycodone following the administration of Oxycodone Hydrochloride Oral Solution, USP was approximately 3.5 hours.. Special Populations. Age: Geriatric PopulationInformation obtained from oxycodone tablets indicate that the plasma concentrations of oxycodone did not appear to be increased in patients over of the age of 65.. Hepatic ImpairmentBecause oxycodone is extensively metabolized in the liver, its clearance may decrease in hepatic-impaired patients. dose adjustment is recommended in these patients [see Use in Special Populations (8.6)]. Renal ImpairmentBecause this drug is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function, dose reduction is recommended for renal impaired patients [see Use in Special Populations (8.7)]. Drug Interactions Studies. CYP3A4 InhibitorsCYP3A4 is the major enzyme involved in noroxycodone formation. published study showed that the co-administration of voriconazole, CYP3A4 inhibitor, increased oxycodone AUC and max by 3.6 and 1.7 fold, respectively. CYP3A4 InducersA published study showed that the co-administration of rifampin, drug metabolizing enzyme inducer, decreased oxycodone AUC and max values by 86% and 63%, respectively. CYP2D6 InhibitorsOxycodone is metabolized in part to oxymorphone via the cytochrome p450 isoenzyme CYP2D6. While this pathway may be blocked by variety of drugs (e.g., certain cardiovascular drugs and antidepressants), such blockade has not yet been shown to be of clinical significance with this agent.

CONTRAINDICATIONS SECTION.

4 CONTRAINDICATIONS. Oxycodone Hydrochloride Oral Solution, USP is contraindicated in patients with:Significant respiratory depression [see Warnings and Precautions (5.4)] Acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment [see Warnings and Precautions (5.4)] Known or suspected gastrointestinal obstruction, including paralytic ileus [see Warnings and Precautions (5.12)] Hypersensitivity to oxycodone [see Warnings and Precautions (5.1), Adverse Reactions (6)] Significant respiratory depression [see Warnings and Precautions (5.4)] Acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment [see Warnings and Precautions (5.4)] Known or suspected gastrointestinal obstruction, including paralytic ileus [see Warnings and Precautions (5.12)] Hypersensitivity to oxycodone [see Warnings and Precautions (5.1), Adverse Reactions (6)] Acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment [see Warnings and Precautions (5.4)] Known or suspected gastrointestinal obstruction, including paralytic ileus [see Warnings and Precautions (5.12)] Hypersensitivity to oxycodone [see Warnings and Precautions (5.1), Adverse Reactions (6)] Significant respiratory depression. 4) Acute or severe bronchial asthma in an unmonitored setting or in absence of resuscitative equipment. 4) Known or suspected gastrointestinal obstruction, including paralytic ileus. 4) Hypersensitivity to oxycodone. 4) Significant respiratory depression. 4) Acute or severe bronchial asthma in an unmonitored setting or in absence of resuscitative equipment. 4) Known or suspected gastrointestinal obstruction, including paralytic ileus. 4) Hypersensitivity to oxycodone. 4).

DEPENDENCE SECTION.

9.3 Dependence. Both tolerance and physical dependence can develop during chronic opioid therapy. Tolerance is the need for increasing doses of opioids to maintain defined effect such as analgesia (in the absence of disease progression or other external factors). Tolerance may occur to both the desired and undesired effects of drugs, and may develop at different rates for different effects.Physical dependence results in withdrawal symptoms after abrupt discontinuation or significant dosage reduction of drug. Withdrawal also may be precipitated through the administration of drugs with opioid antagonist activity (e.g., naloxone, nalmefene), mixed agonist/antagonist analgesics (e.g.,pentazocine, butorphanol, nalbuphine), or partial agonists (e.g., buprenorphine).Physical dependence may not occur to clinically significant degree until after several days to weeks of continued opioid usage.Oxycodone Hydrochloride Oral Solution, USP should not be abruptly discontinued in physically dependent patient [see Dosage and Administration (2.4)] If Oxycodone Hydrochloride Oral Solution, USP is abruptly discontinued in physically-dependent patient, withdrawal syndrome may occur. Some or all of the following can characterize this syndrome: 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. Infants born to mothers physically dependent on opioids will also be physically dependent and may exhibit respiratory difficulties and withdrawal signs [see Use in Specific Populations (8.1)].

Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and Precautions (5)]. Initiate the dosing regimen for each patient individually, taking into account the patients severity of pain, patient response, prior analgesic treatment experience, and risk factors for addiction, abuse, and misuse [see Warnings and Precautions (5.2)]. Monitor patients closely for respiratory depression, especially within the first 24-72 hours of initiating therapy and following dosage increases with oxycodone hydrochloride solution and adjust the dosage accordingly [see ]. Monitor patients closely for respiratory depression, especially within the first 24 to 72 hours of initiating therapy and following dosage increases with oxycodone hydrochloride solution and adjust the dosage accordingly [see Warnings and Precautions (5.4)]. 2.2Initial Dosage. Use of Oxycodone Hydrochloride Oral Solution as the First Opioid AnalgesicInitiate treatment with Oxycodone Hydrochloride Oral Solution, USP: to 15 mg every to hours as needed for pain.For control of severe chronic pain, Oxycodone Hydrochloride Oral Solution, USP should be administered on regularly scheduled basis, every to hours, at the lowest dosage level that will achieve adequate analgesia.As with any opioid drug product, adjust the dosing regimen for each patient individually, taking into account the patients prior analgesic treatment experience. In the selection of the initial dose of oxycodone hydrochloride, give attention to the following:the total daily dose, potency and specific characteristics of the opioid the patient has been taking previously;the reliability of the relative potency estimate used to calculate the equivalent oxycodone hydrochloride dose needed;the patients degree of opioid tolerance;the general condition and medical status of the patient;concurrent medications;the type and severity of the patients pain;risk factors for abuse, addiction or diversion, including prior history of abuse, addiction or diversion.The following dosing recommendations, therefore, can only be considered as suggested approaches to what is actually 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 management 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.. the total daily dose, potency and specific characteristics of the opioid the patient has been taking previously;. the reliability of the relative potency estimate used to calculate the equivalent oxycodone hydrochloride dose needed;. the patients degree of opioid tolerance;. the general condition and medical status of the patient;. concurrent medications;. the type and severity of the patients pain;. risk factors for abuse, addiction or diversion, including prior history of abuse, addiction or diversion.. Conversion from Other Opioids to Oxycodone Hydrochloride Oral SolutionThere is inter-patient variability in the potency of opioid drugs and opioid formulations. Therefore, conservative approach is advised when determining the total daily dosage of Oxycodone Hydrochloride Oral Solution, USP. It is safer to underestimate patients 24-hour Oxycodone Hydrochloride Oral Solution, USP than to overestimate the 24-hour Oxycodone Hydrochloride Oral Solution, USP dosage and manage an adverse reaction due to overdose.Consider the following general points regarding opioid conversions.In converting patients from other opioids to Oxycodone Hydrochloride Oral Solution, USP, close observation and adjustment of dosage based upon the patients response to Oxycodone Hydrochloride Oral Solution, USP 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 Oxycodone Hydrochloride Oral Solution to Extended-Release OxycodoneThe relative bioavailability of Oxycodone Hydrochloride Oral Solution, USP compounds to extended-release oxycodone is unknown, so conversion to extended-release tablets/capsules must be accompanied by close observation for signs of excessive sedation and respiratory depression.. 2.3Titration and Maintenance of Therapy. Individually titrate Oxycodone Hydrochloride Oral Solution, USP to dose that provides adequate analgesia and minimizes adverse reactions. Continually reevaluate patients receiving Oxycodone Hydrochloride Oral Solution, USP to assess the maintenance of pain control and the relative incidence of adverse reactions, as well as monitoring for the development of addiction, abuse, or misuse [see Warnings and Precautions (5.2)]. 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 Oral Solution, USP dosage. If unacceptable opioid-related adverse reactions are observed, consider reducing the dosage. Adjust the dosage to obtain an appropriate balance between management of pain and opioid-related adverse reactions.. 2.4Discontinuation of Oxycodone Hydrochloride Oral Solution. When patient who has been taking Oxycodone Hydrochloride Oral Solution regularly and may be physically dependent no longer requires therapy with oxycodone hydrochloride oral solution, taper the dose gradually, by 25% to 50% every to days, while monitoring carefully for signs and symptoms of withdrawal. If the patient develops these signs or symptoms, raise the dose to the previous level and taper more slowly, either by increasing the interval between decreases, decreasing the amount of change in dose, or both. Do not abruptly discontinue Oxycodone Hydrochloride Oral Solution, USP in physically-dependent patient [see Warnings and Precautions (5.14), Drug Abuse and Dependence (9.3)].

DRUG ABUSE AND DEPENDENCE SECTION.

9 DRUG ABUSE AND DEPENDENCE. 9.1 Controlled Substance. Oxycodone Hydrochloride Oral Solution, USP contains oxycodone, Schedule II controlled substance.. 9.2 Abuse. Oxycodone Hydrochloride Oral Solution, USP contains oxycodone, substance with high potential for abuse similar to other opioids including fentanyl, hydrocodone, hydromorphone, methadone, morphine, oxymorphone, and tapentadol. Oxycodone Hydrochloride Oral Solution, USP can be abused and is subject to misuse, addiction, and criminal diversion [see Warnings and Precautions (5.2)] All patients treated with opioids require careful monitoring for signs of abuse and addiction, because use of opioid analgesic products carries the risk of addiction even under appropriate medical use.Prescription drug abuse is the intentional non-therapeutic use of prescription drug, even once, for its rewarding psychological or physiological effects.Drug addiction is cluster of behavioral, cognitive, and physiological phenomena that develop after repeated substance use and includes: strong desire to take the drug, difficulties in controlling its use, persisting in its use despite harmful consequences, higher priority given to drug use than to other activities and obligations, increased tolerance, and sometimes physical withdrawal.Drug-seeking behavior is very common in persons with substance use disorders. Drug-seeking tactics include emergency calls or visits near the end of office hours, refusal to undergo appropriate examination, testing, or referral, repeated loss of prescriptions, tampering with prescriptions, and reluctance to provide prior medical records or contact information for other treating health care provider(s). Doctor shopping (visiting multiple prescribers to obtain additional prescriptions) is common among drug abusers and people suffering from untreated addiction. Preoccupation with achieving adequate pain relief can be appropriate behavior in patient with poor pain control.Abuse and addiction are separate and distinct from physical dependence and tolerance. Health care providers should be aware that addiction may not be accompanied by concurrent tolerance and symptoms of physical dependence in all addicts. In addition, abuse of opioids can occur in the absence of true addiction. Oxycodone Hydrochloride Oral Solution, USP, like other opioids, can be diverted for non-medical use into illicit channels of distribution. Careful record-keeping of prescribing information, including quantity, frequency, and renewal requests, as required by state and federal law, is strongly advised. Proper assessment of the patient, proper prescribing practices, periodic re-evaluation of therapy, and proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs.. Risks Specific to Abuse of Oxycodone Hydrochloride Oral SolutionOxycodone Hydrochloride Oral Solution, USP is for oral use only. Abuse of oxycodone poses risk of overdose and death. The risk is increased with concurrent abuse of alcohol and other central nervous system depressants. Parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and HIV.. 9.3 Dependence. Both tolerance and physical dependence can develop during chronic opioid therapy. Tolerance is the need for increasing doses of opioids to maintain defined effect such as analgesia (in the absence of disease progression or other external factors). Tolerance may occur to both the desired and undesired effects of drugs, and may develop at different rates for different effects.Physical dependence results in withdrawal symptoms after abrupt discontinuation or significant dosage reduction of drug. Withdrawal also may be precipitated through the administration of drugs with opioid antagonist activity (e.g., naloxone, nalmefene), mixed agonist/antagonist analgesics (e.g.,pentazocine, butorphanol, nalbuphine), or partial agonists (e.g., buprenorphine).Physical dependence may not occur to clinically significant degree until after several days to weeks of continued opioid usage.Oxycodone Hydrochloride Oral Solution, USP should not be abruptly discontinued in physically dependent patient [see Dosage and Administration (2.4)] If Oxycodone Hydrochloride Oral Solution, USP is abruptly discontinued in physically-dependent patient, withdrawal syndrome may occur. Some or all of the following can characterize this syndrome: 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. Infants born to mothers physically dependent on opioids will also be physically dependent and may exhibit respiratory difficulties and withdrawal signs [see Use in Specific Populations (8.1)].

DRUG INTERACTIONS SECTION.

7 DRUG INTERACTIONS. Table includes clinically significant drug interactions with Oxycodone Hydrochloride Oral Solution, USP.Table 1: Clinically Significant Drug Interactions with Oxycodone Hydrochloride Oral Solution, USPInhibitors of CYP3A4 and CYP2D6Clinical Impact:The concomitant use of Oxycodone Hydrochloride Oral Solution, USP 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 Oral Solution, USP and CYP2D6 and CYP3A4 inhibitors, particularly when an inhibitor is added after stable dose of Oxycodone Hydrochloride Oral Solution, USP is achieved [see Warnings and Precautions (5.6)]. After stopping CYP3A4 inhibitor, as the effects of the inhibitor decline, the oxycodone plasma concentration will decrease [see Clinical Pharmacology (12.3)], resulting in decreased opioid efficacy or withdrawal syndrome in patients who had developed physical dependence to oxycodone. Intervention:If concomitant use is necessary, consider dosage reduction of Oxycodone Hydrochloride Oral Solution, USP until stable drug effects are achieved. Monitor patients for respiratory depression and sedation at frequent intervals. If CYP3A4 inhibitor is discontinued, consider increasing the Oxycodone Hydrochloride Oral Solution, USP dosage until stable drug effects are achieved [see Dosage and Administration (2.2)]. Monitor for signs of opioid withdrawal. Examples:Macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g. ketoconazole), protease inhibitors (e.g. ritonavir)CYP3A4 InducersClinical Impact:The concomitant use of Oxycodone Hydrochloride Oral Solution, USP and CYP3A4 inducers can decrease the plasma concentration of oxycodone [see Clinical Pharmacology (12.3)], resulting in decreased efficacy or onset of withdrawal syndrome in patients who have developed physical dependence to oxycodone [see Warnings and Precautions (5.6)]. After stopping CYP3A4 inducer, as the effects of the inducer decline, the oxycodone plasma concentration will increase [see Clinical Pharmacology (12.3)], 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 Oral Solution, USP dosage until stable drug effects are achieved. Monitor for signs of opioid withdrawal. If CYP3A4 inducer is discontinued, consider Oxycodone Hydrochloride Oral Solution, USP dosage reduction and monitor for signs of respiratory depression.Examples:Rifampin, carbamazepine, phenytoinBenzodiazepines and other Central Nervous System (CNS) DepressantsClinical Impact:Due to additive pharmacologic effect, the concomitant use of benzodiazepines or other CNS depressants including alcohol, increases the risk of 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. Follow patients closely for signs of respiratory depression and sedation [see Warnings and Precautions (5.7)]. Examples:Benzodiazepines and other sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids, alcoholSerotonergic DrugsClinical Impact:The concomitant use of opioids with other drugs that affect the serotonergic neurotransmitter system has resulted in serotonin syndrome see Warnings and Precautions (5.9) ]. Intervention:If concomitant use is warranted, carefully observe the patient, particularly during treatment initiation and dose adjustment. Discontinue Oxycodone Hydrochloride Oral Solution, USP 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), 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) [see Warnings and Precautions (5.4)]. Intervention:The use of Oxycodone Hydrochloride Oral Solution, USP 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, linezolidMixed Agonist/Antagonist and Partial Agonist Opioid AnalgesicsClinical Impact:May reduce the analgesic effect of Oxycodone Hydrochloride Oral Solution, USP and/or precipitate withdrawal symptoms.Intervention:Avoid concomitant use.Examples:butorphanol, nalbuphine, pentazocine, buprenorphineMuscle RelaxantsClinical Impact:Oxycodone may enhance the neuromuscular blocking action of skeletal muscle relaxants and produce an increased degree of respiratory depression.Intervention:Monitor patients for signs of respiratory depression that may be greater than otherwise expected and decrease the dosage of Oxycodone Hydrochloride Oral Solution, USP and/or the muscle relaxant as necessary.DiureticsClinical Impact:Opioids can reduce the efficacy of diuretics by inducing the release of antidiuretic hormone.Intervention:Monitor patients for signs of diminished diuresis and/or effects on blood pressure and increase the dosage of the diuretic as needed.Anticholinergic DrugsClinical Impact:The concomitant use of anticholinergic drugs may increase risk of urinary retention and/or severe constipation, which may lead to paralytic ileus.Intervention:Monitor patients for signs of urinary retention or reduced gastric motility when Oxycodone Hydrochloride Oral Solution, USP is used concomitantly with anticholinergic drugs.. Serotonergic Drugs: Concomitant use may result in serotonin syndrome. Discontinue Oxycodone Hydrochloride Oral Solution, USP if serotonin syndrome is suspected. 7) Monoamine Oxidase Inhibitors (MAOIs): Can potentiate the effects of oxycodone. Avoid concomitant use in patients receiving MAOIs or within 14 days of stopping treatment with an MAOI. 7) Mixed Agonist/Antagonist and Partial Agonist Opioid Analgesics: Avoid use with Oxycodone Hydrochloride Oral Solution, USP because they may reduce analgesic effect of Oxycodone Hydrochloride Oral Solution, USP or precipitate withdrawal symptoms. 7) Serotonergic Drugs: Concomitant use may result in serotonin syndrome. Discontinue Oxycodone Hydrochloride Oral Solution, USP if serotonin syndrome is suspected. 7) Monoamine Oxidase Inhibitors (MAOIs): Can potentiate the effects of oxycodone. Avoid concomitant use in patients receiving MAOIs or within 14 days of stopping treatment with an MAOI. 7) Mixed Agonist/Antagonist and Partial Agonist Opioid Analgesics: Avoid use with Oxycodone Hydrochloride Oral Solution, USP because they may reduce analgesic effect of Oxycodone Hydrochloride Oral Solution, USP or precipitate withdrawal symptoms. 7).

FEMALES & MALES OF REPRODUCTIVE POTENTIAL SECTION.

8.3 Females and Males of Reproductive Potential. InfertilityChronic use of opioids may cause reduced fertility in females and males of reproductive potential. It is not known whether these effects on fertility are reversible [see Adverse Reactions (6), Clinical Pharmacology (12.2)].

GERIATRIC USE SECTION.

8.5 Geriatric Use. Elderly patients (aged 65 years or older) may have increased sensitivity to oxycodone. In general, use caution when selecting 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.Respiratory depression is the chief risk for elderly patients treated with opioids, and has occurred after large initial doses were administered to patients who were not opioid-tolerant or when opioids were co-administered with other agents that depress respiration. Titrate the dosage of Oxycodone Hydrochloride Oral Solution, USP slowly in geriatric patients and monitor closely for signs of central nervous system and respiratory depression [see Warnings and Precautions (5.7)]. Oxycodone is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

LACTATION SECTION.

8.2 Lactation. Risk SummaryOxycodone is present in breast milk. Published lactation studies report variable concentrations of oxycodone in breast milk with administration of immediate-release oxycodone to nursing mothers in the early postpartum period. The lactation studies did not assess breastfed infants for potential adverse reactions. Lactation studies have not been conducted with Oxycodone Hydrochloride Oral Solution, USP, and no information is available on the effects of the drug on the breastfed infant or the effects of the drug on milk production.The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for Oxycodone Hydrochloride Oral Solution, USP and any potential adverse effects on the breastfed infant from Oxycodone Hydrochloride Oral Solution, USP or from the underlying maternal condition.. Clinical ConsiderationsMonitor infants exposed to Oxycodone Hydrochloride Oral Solution, USP through breast milk for excess sedation and respiratory depression. Withdrawal symptoms can occur in breastfed infants when maternal administration of an opioid analgesic is stopped, or when breast-feeding is stopped.

MECHANISM OF ACTION SECTION.

12.1 Mechanism of Action. Oxycodone is full opioid agonist and is relatively selective for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of oxycodone is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with oxycodone. Clinically, dosage is titrated to provide adequate analgesia and may be limited by adverse reactions, including respiratory and CNS depression.The precise mechanism of the analgesic action is unknown. However, specific CNS opioid receptors for endogenous compounds with opioid-like activity have been identified throughout the brain and spinal cord and are thought to play role in the analgesic effects of this drug.

NONCLINICAL TOXICOLOGY SECTION.

13 NONCLINICAL TOXICOLOGY. 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. CarcinogenesisLong-term studies in animals to evaluate the carcinogenic potential of oxycodone have not been conducted.. MutagenesisOxycodone hydrochloride was genotoxic in an in vitro mouse lymphoma assay in the presence of metabolic activation. There was no evidence of genotoxic potential in an in vitro bacterial reverse mutation assay (Salmonella typhimurium and Escherichia coli) or in an assay for chromosomal aberrations in vivo mouse bone marrow micronucleus assay). Impairment of FertilityStudies in animals to evaluate the potential impact of oxycodone on fertility have not been conducted.

OVERDOSAGE SECTION.

10 OVERDOSAGE. Clinical PresentationAcute overdose with Oxycodone Hydrochloride Oral Solution, USP 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, partial or complete airway obstruction, atypical snoring, and death. Marked mydriasis rather than miosis may be seen with hypoxia in overdose situations [see Clinical Pharmacology (12.2)]. Treatment of OverdoseIn case of overdose, priorities are the reestablishment of 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 techniques. The opioid antagonists, naloxone or nalmefene, are specific antidotes to respiratory depression resulting from opioid overdose. For clinically significant respiratory or circulatory depression secondary to oxycodone overdose, administer an opioid antagonist. Opioid antagonists should not be administered in the absence of clinically significant respiratory or circulatory depression secondary to oxycodone overdose.Because the duration of opioid reversal is expected to be less than the duration of action of oxycodone in Oxycodone Hydrochloride Oral Solution, USP, carefully monitor the patient until spontaneous respiration is reliably re-established. If the response to an opioid antagonist is suboptimal or only brief in nature, administer additional antagonist as directed by the products 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 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.

8.4 Pediatric Use. The safety and efficacy of Oxycodone Hydrochloride Oral Solution, USP in pediatric patients below the age of 18 have not been established.

PHARMACODYNAMICS SECTION.

12.2 Pharmacodynamics. Effects on Central Nervous System (CNS)Oxycodone produces respiratory depression by direct action on brain stem respiratory centers. The respiratory depression involves reduction in the responsiveness of the brain stem respiratory centers to both increases in carbon dioxide tension and to electrical stimulation.Oxycodone causes miosis, even in total darkness. Pinpoint pupils are sign of opioid overdose but are not pathognomonic (e.g., pontine lesions of hemorrhagic or ischemic origins may produce similar findings). Marked mydriasis rather than miosis may be seen due to hypoxia in overdose situations. Effects on the Gastrointestinal Tract and Other Smooth MuscleOxycodone causes reduction in motility associated with an increase in smooth muscle tone in the antrum of the stomach and duodenum. Digestion of food in the small intestine is delayed and propulsive contractions are decreased. Propulsive peristaltic waves in the colon are decreased, while tone may be increased to the point of spasm resulting in constipation. Other-opioid induced effects may include reduction in biliary and pancreatic secretions, spasm of sphincter of Oddi, and transient elevations in serum amylase.. Effects on the Cardiovascular SystemOxycodone produces peripheral vasodilation which may result in orthostatic hypotension or syncope. Manifestations of histamine release and/or peripheral vasodilation may include pruritus, flushing, red eyes and sweating and/or orthostatic hypotension.. Effects on the Endocrine SystemOpioids inhibit the secretion of adrenocorticotropic hormone (ACTH), cortisol, and luteinizing hormone (LH) in humans [see Adverse Reactions (6)]. They also stimulate prolactin, growth hormone (GH) secretion, and pancreatic secretion of insulin and glucagon. Chronic use of opioids may influence the hypothalamic-pituitary-gonadal axis, leading to androgen deficiency that may manifest as low libido, impotence, erectile dysfunction, amenorrhea, or infertility. The causal role of opioids in the clinical syndrome of hypogonadism is unknown because the various medical, physical, lifestyle, and psychological stressors that may influence gonadal hormone levels have not been adequately controlled for in studies conducted to date [see Adverse Reactions (6)]. Effects on the Immune SystemOpioids have been shown to have variety of effects on components of the immune system in in vitro and animal models. The clinical significance of these findings is unknown. Overall, the effects of opioids appear to be modestly immunosuppressive.. Concentration-Efficacy RelationshipsThe minimum effective analgesic concentration will vary widely among patients, especially among patients who have been previously treated with potent agonist opioids. The minimum effective analgesic concentration of oxycodone for any individual patient may increase over time due to an increase in pain, the development of new pain syndrome and/or the development of analgesic tolerance [see Dosage and Administration (2.1, 2.2)]. Concentration-Adverse Reaction RelationshipsThere is relationship between increasing oxycodone plasma concentration and increasing frequency of dose-related opioid adverse reactions such as nausea, vomiting, CNS effects, and respiratory depression. In opioid-tolerant patients, the situation may be altered by the development of tolerance to opioid-related adverse reactions [see Dosage and Administration (2.1, 2.2, 2.3)].

PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics. The activity of Oxycodone Hydrochloride Oral Solution, USP is primarily due to the parent drug oxycodone.. AbsorptionThe oral bioavailability of oxycodone is 60 to 87%. This high oral bioavailability (compared to other oral opioids) is due to lower pre-systemic and/or first-pass metabolism of oxycodone.. Food EffectPresence of food may slightly delay the rate (C max and max) and enhance the extent of absorption (AUC) of oxycodone from Oxycodone Hydrochloride Oral Solution, USP. Overall, food is not expected to have clinically significant impact on the absorption of Oxycodone Hydrochloride Oral Solution, USP. DistributionFollowing intravenous administration, the volume of distribution (Vss) for oxycodone was 2.6 L/kg. Plasma protein binding of oxycodone at 37C and pH of 7.4 was about 45%. Oxycodone has been found in breast milk [see Use in Specific Populations (8.2) ]. Elimination. MetabolismOxycodone hydrochloride is extensively metabolized to noroxycodone, oxymorphone, noroxymorphone, which are subsequently glucuronidated. CYP3A4 mediated N-demethylation to noroxycodone is the primary metabolic pathway of oxycodone with less contribution from CYP2D6 mediated O-demethylation to oxymorphone. Therefore, the formation of these and related metabolites can, in theory, be affected by other drugs. The major circulating metabolite is noroxycodone with an AUC ratio of 0.6 relative to that of oxycodone. Noroxycodone is reported to be considerably weaker analgesic than oxycodone. Oxymorphone, although possessing analgesic activity, is present in the plasma only in low concentrations. The correlation between oxymorphone concentrations and opioid effects was much less than that seen with oxycodone plasma concentrations. The analgesic activity profile of other metabolites is not known.. ExcretionOxycodone and its metabolites are excreted primarily via the kidney. The amounts measured in the urine have been reported as follows: free oxycodone up to 19%; conjugated oxycodone up to 50%; free oxymorphone 0%; conjugated oxymorphone <= 14%; both free and conjugated noroxycodone have been found in the urine but not quantified. The total plasma clearance was 0.8 L/min for adults. Apparent elimination half-life of oxycodone following the administration of Oxycodone Hydrochloride Oral Solution, USP was approximately 3.5 hours.. Special Populations. Age: Geriatric PopulationInformation obtained from oxycodone tablets indicate that the plasma concentrations of oxycodone did not appear to be increased in patients over of the age of 65.. Hepatic ImpairmentBecause oxycodone is extensively metabolized in the liver, its clearance may decrease in hepatic-impaired patients. dose adjustment is recommended in these patients [see Use in Special Populations (8.6)]. Renal ImpairmentBecause this drug is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function, dose reduction is recommended for renal impaired patients [see Use in Special Populations (8.7)]. Drug Interactions Studies. CYP3A4 InhibitorsCYP3A4 is the major enzyme involved in noroxycodone formation. published study showed that the co-administration of voriconazole, CYP3A4 inhibitor, increased oxycodone AUC and max by 3.6 and 1.7 fold, respectively. CYP3A4 InducersA published study showed that the co-administration of rifampin, drug metabolizing enzyme inducer, decreased oxycodone AUC and max values by 86% and 63%, respectively. CYP2D6 InhibitorsOxycodone is metabolized in part to oxymorphone via the cytochrome p450 isoenzyme CYP2D6. While this pathway may be blocked by variety of drugs (e.g., certain cardiovascular drugs and antidepressants), such blockade has not yet been shown to be of clinical significance with this agent.

8.1 Pregnancy. Risk SummaryProlonged use of opioid analgesics during pregnancy may cause neonatal opioid withdrawal syndrome [see Warnings and Precautions (5.4)]. Available data with Oxycodone Hydrochloride Oral Solution, USP are insufficient to inform drug-associated risk for major birth defects and miscarriage. Animal reproduction studies with oral administrations of oxycodone hydrochloride in rats and rabbits during the period of organogenesis at doses 2.6 and 8.1 times, respectively, the human dose of 60 mg/day did not reveal evidence of teratogenicity or embryo-fetal toxicity. In several published studies, treatment of pregnant rats with oxycodone at clinically relevant doses and below, resulted in neurobehavioral effects in offspring [see Data] Based on animal data, advise pregnant women of the potential risk to fetus. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is to 4% and 15 to 20%, respectively.. Clinical Considerations. Fetal/Neonatal Adverse ReactionsProlonged use of opioid analgesics during pregnancy for medical or nonmedical purposes can result in physical dependence in the neonate and neonatal opioid withdrawal syndrome shortly after birth. Neonatal opioid withdrawal syndrome presents as irritability, hyperactivity and abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea, and failure to gain weight. The onset, duration, and severity of neonatal opioid withdrawal syndrome vary based on the specific opioid used, duration of use, timing and amount of last maternal use, and rate of elimination of the drug by the newborn. Observe newborns for symptoms of neonatal opioid withdrawal syndrome and manage accordingly [see Warnings and Precautions (5.5)]. Labor or DeliveryOpioids cross the placenta and may produce respiratory depression and psycho-physiologic effects in neonates. An opioid antagonist, such as naloxone, must be available for reversal of opioid-induced respiratory depression in the neonate. Oxycodone Hydrochloride Oral Solution, USP is not recommended for use in pregnant women during or immediately prior to labor, when other analgesic techniques are more appropriate. Opioid analgesics, including Oxycodone Hydrochloride Oral Solution, USP, can 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 dilation, which tends to shorten labor. Monitor neonates exposed to opioid analgesics during labor for signs of excess sedation and respiratory depression.. Data. Animal DataIn embryo-fetal development studies in rats and rabbits, pregnant animals received oral doses of oxycodone hydrochloride administered during the period of organogenesis up to 16 mg/kg/day and up 25 mg/kg/day, respectively. These studies revealed no evidence of teratogenicity or embryo-fetal toxicity due to oxycodone. The highest doses tested in rats and rabbits were equivalent to approximately 2.6 and 8.1 times an adult human dose of 60 mg/day, respectively, on mg/m basis. In published studies, offspring of pregnant rats administered oxycodone during gestation have been reported to exhibit neurobehavioral effects including altered stress responses, increased anxiety-like behavior (2 mg/kg/day IV from Gestation Day to 21 and Postnatal Day 1, 3, and 5; 0.3-times an adult human dose of 60 mg/day, on mg/m basis) and altered learning and memory (15 mg/kg/day orally from breeding through parturition; 2.4 times an adult human dose of 60 mg/day, on mg/m basis).

Animal DataIn embryo-fetal development studies in rats and rabbits, pregnant animals received oral doses of oxycodone hydrochloride administered during the period of organogenesis up to 16 mg/kg/day and up 25 mg/kg/day, respectively. These studies revealed no evidence of teratogenicity or embryo-fetal toxicity due to oxycodone. The highest doses tested in rats and rabbits were equivalent to approximately 2.6 and 8.1 times an adult human dose of 60 mg/day, respectively, on mg/m basis. In published studies, offspring of pregnant rats administered oxycodone during gestation have been reported to exhibit neurobehavioral effects including altered stress responses, increased anxiety-like behavior (2 mg/kg/day IV from Gestation Day to 21 and Postnatal Day 1, 3, and 5; 0.3-times an adult human dose of 60 mg/day, on mg/m basis) and altered learning and memory (15 mg/kg/day orally from breeding through parturition; 2.4 times an adult human dose of 60 mg/day, on mg/m basis). 8.2 Lactation. Risk SummaryOxycodone is present in breast milk. Published lactation studies report variable concentrations of oxycodone in breast milk with administration of immediate-release oxycodone to nursing mothers in the early postpartum period. The lactation studies did not assess breastfed infants for potential adverse reactions. Lactation studies have not been conducted with Oxycodone Hydrochloride Oral Solution, USP, and no information is available on the effects of the drug on the breastfed infant or the effects of the drug on milk production.The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for Oxycodone Hydrochloride Oral Solution, USP and any potential adverse effects on the breastfed infant from Oxycodone Hydrochloride Oral Solution, USP or from the underlying maternal condition.. Clinical ConsiderationsMonitor infants exposed to Oxycodone Hydrochloride Oral Solution, USP through breast milk for excess sedation and respiratory depression. Withdrawal symptoms can occur in breastfed infants when maternal administration of an opioid analgesic is stopped, or when breast-feeding is stopped.. 8.3 Females and Males of Reproductive Potential. InfertilityChronic use of opioids may cause reduced fertility in females and males of reproductive potential. It is not known whether these effects on fertility are reversible [see Adverse Reactions (6), Clinical Pharmacology (12.2)] . 8.4 Pediatric Use. The safety and efficacy of Oxycodone Hydrochloride Oral Solution, USP in pediatric patients below the age of 18 have not been established.. 8.5 Geriatric Use. Elderly patients (aged 65 years or older) may have increased sensitivity to oxycodone. In general, use caution when selecting 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.Respiratory depression is the chief risk for elderly patients treated with opioids, and has occurred after large initial doses were administered to patients who were not opioid-tolerant or when opioids were co-administered with other agents that depress respiration. Titrate the dosage of Oxycodone Hydrochloride Oral Solution, USP slowly in geriatric patients and monitor closely for signs of central nervous system and respiratory depression [see Warnings and Precautions (5.7)]. Oxycodone is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. 8.6Hepatic Impairment. Since oxycodone is extensively metabolized in the liver, its clearance may decrease in patients with hepatic impairment. Initiate therapy in these patients with lower than usual dosage of Oxycodone Hydrochloride Oral Solution, USP and titrate carefully. Monitor closely for adverse events such as respiratory depression, sedation, and hypotension [see Clinical Pharmacology (12.3)]. 8.7Renal Impairment. Information from oxycodone tablets indicate that patients with renal impairment had higher plasma concentrations of oxycodone than subjects with normal renal function.Initiate therapy with lower than usual dosage of Oxycodone Hydrochloride Oral Solution, USP and titrate carefully. Monitor closely for adverse events such as respiratory depression, sedation, and hypotension [see Clinical Pharmacology (12.3)].

WARNINGS AND PRECAUTIONS SECTION.

5 WARNINGS AND PRECAUTIONS. Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients: Monitor closely, particularly during initiation and titration. 5.8) Adrenal Insufficiency: If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off of the opioid. 5.9) Severe Hypotension: Monitor during dosage initiation and titration. Avoid use of Oxycodone Hydrochloride Oral Solution, USP in patients with circulatory shock. 5.10) Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness: Monitor for sedation and respiratory depression. Avoid use of Oxycodone Hydrochloride Oral Solution in patients with impaired consciousness or coma. 5.11) Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients: Monitor closely, particularly during initiation and titration. 5.8) Adrenal Insufficiency: If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off of the opioid. 5.9) Severe Hypotension: Monitor during dosage initiation and titration. Avoid use of Oxycodone Hydrochloride Oral Solution, USP in patients with circulatory shock. 5.10) Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness: Monitor for sedation and respiratory depression. Avoid use of Oxycodone Hydrochloride Oral Solution in patients with impaired consciousness or coma. 5.11) 5.1Risk of Accidental Overdose and Death due to Medication Errors. Dosing errors can result in accidental overdose and death. Avoid dosing errors that may result from confusion between mg and mL and confusion with oxycodone solutions of different concentrations, when prescribing, dispensing, and administering Oxycodone Hydrochloride Oral Solution, USP. Ensure that the dose is communicated clearly and dispensed accurately. Always dispense in the mL unit dose cup when administering Oxycodone Hydrochloride Oral Solution, USP to ensure the dose is measured and administered accurately. Do not use teaspoon or tablespoon to measure dose. household teaspoon or tablespoon is not an adequate measuring device. Given the inexactitude of the household spoon measure and the possibility of using tablespoon instead of teaspoon, which could lead to overdosage, it is strongly recommended that, if the enclosed calibrated measuring cup becomes lost, caregivers obtain and use calibrated measuring device. Health care providers should recommend calibrated device that can measure and deliver the prescribed dose accurately, and instruct caregivers to use extreme caution in measuring the dosage.. 5.2Addiction, Abuse and Misuse. Oxycodone Hydrochloride Oral Solution, USP contains oxycodone, Schedule II controlled substance. As an opioid, Oxycodone Hydrochloride Oral Solution, USP exposes users to the risks of addiction, abuse, and misuse [see Drug Abuse and Dependence (9)]. Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed Oxycodone Hydrochloride Oral Solution, USP. Addiction can occur at recommended dosages and if the drug is misused or abused.Assess each patients risk for opioid addiction, abuse, or misuse prior to prescribing Oxycodone Hydrochloride Oral Solution, USP, and monitor all patients receiving Oxycodone Hydrochloride Oral Solution, USP for the development of these behaviors and conditions. Risks are increased in patients with 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 Oxycodone Hydrochloride Oral Solution, USP, but use in such patients necessitates intensive counseling about the risks and proper use of Oxycodone Hydrochloride Oral Solution, USP along with intensive monitoring for signs of addiction, abuse, and misuse.Opioids are sought by drug abusers and people with addiction disorders and are subject to criminal diversion. Consider these risks when prescribing or dispensing Oxycodone Hydrochloride Oral Solution, USP. Strategies to reduce these risks include prescribing the drug in the smallest appropriate quantity and advising the patient on the proper disposal of unused drug [see Patient Counseling Information (17)]. 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. 5.3Opioid 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 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 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 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.To obtain further information on the opioid analgesic REMS and for 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.. Complete 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.. 5.4Life-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 patients clinical status [see Overdosage (10)]. Carbon dioxide (CO 2) 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 Oxycodone Hydrochloride Oral Solution, USP, the risk is greatest during the initiation of therapy or following dosage increase. Monitor patients closely for respiratory depression, especially within the first 24 to 72 hours of initiating therapy with and following dosage increases of Oxycodone Hydrochloride Oral Solution, USP.To reduce the risk of respiratory depression, proper dosing and titration of Oxycodone Hydrochloride Oral Solution, USP are essential [see Dosage and Administration (2)]. Overestimating the Oxycodone Hydrochloride Oral Solution, USP dosage when converting patients from another opioid product can result in fatal overdose with the first dose. Accidental ingestion of even one dose of Oxycodone Hydrochloride Oral Solution, USP, especially by (in) children, can result in respiratory depression and death due to an overdose of oxycodone.. 5.5Neonatal Opioid Withdrawal Syndrome. Prolonged use of Oxycodone Hydrochloride Oral Solution, USP 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 prolonged period of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available [see Use in Specific Populations (8.1), Patient Counseling Information (17)]. 5.6Risks of Concomitant Use or Discontinuation of Cytochrome P450 3A4 Inhibitors and Inducers. Concomitant use of Oxycodone Hydrochloride Oral Solution, USP with 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 [see Warnings and Precautions (5.4)], particularly when an inhibitor is added after stable dose of Oxycodone Hydrochloride Oral Solution, USP is achieved. Similarly, discontinuation of CYP3A4 inducer, such as rifampin, carbamazepine, and phenytoin, in Oxycodone Hydrochloride Oral Solution-treated patients may increase oxycodone plasma concentrations and prolong opioid adverse reactions. When using Oxycodone Hydrochloride Oral Solution, USP with CYP3A4 inhibitors or discontinuing CYP3A4 inducers in Oxycodone Hydrochloride Oral Solution-treated patients, monitor patients closely at frequent intervals and consider dosage reduction of Oxycodone Hydrochloride Oral Solution, USP until stable drug effects are achieved [see Dosage and Administration (2.1), Drug Interactions (7)]. Concomitant use of Oxycodone Hydrochloride Oral Solution, USP with CYP3A4 inducers or discontinuation of an CYP3A4 inhibitor could decrease oxycodone plasma concentrations, decrease opioid efficacy or, possibly, lead to withdrawal syndrome in patient who had developed physical dependence to oxycodone. When using Oxycodone Hydrochloride Oral Solution, USP with CYP3A4 inducers or discontinuing CYP3A4 inhibitors, monitor patients closely at frequent intervals and consider increasing the opioid dosage if needed to maintain adequate analgesia or if symptoms of opioid withdrawal occur [see Dosage and Administration (2.1), Drug Interactions (7)]. 5.7Risks from Concomitant Use with Benzodiazepines or Other CNS Depressants. Profound sedation, respiratory depression, coma, and death may result from the concomitant use of Oxycodone Hydrochloride Oral Solution with benzodiazepines or other CNS depressants (e.g., non-benzodiazepine sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids, alcohol). 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 [see Drug Interactions (7)]. If the decision is made to prescribe 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 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 patient already taking benzodiazepine or other CNS depressant, prescribe lower initial dose of the opioid analgesic, and titrate based on clinical response. Follow patients closely for signs and symptoms of respiratory depression and sedation.Advise both patients and caregivers about the risks of respiratory depression and sedation when Oxycodone Hydrochloride Oral Solution, USP is used with benzodiazepines or other CNS depressants (including alcohol and illicit drugs). Advise patients not to drive or operate heavy 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 [see Drug Interactions (7) and Patient Counseling Information (17) ]. 5.8Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients. The use of Oxycodone Hydrochloride Oral Solution, USP 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: Oxycodone Hydrochloride Oral Solution-treated patients with significant chronic obstructive pulmonary disease or cor pulmonale, and those with 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 Oxycodone Hydrochloride Oral Solution, USP [see Warnings and Precautions (5.4)]. Elderly, Cachetic, 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 [see Warnings and Precautions (5.4)]. Monitor such patients closely, particularly when initiating and titrating Oxycodone Hydrochloride Oral Solution, USP and when Oxycodone Hydrochloride Oral Solution, USP is given concomitantly with other drugs that depress respiration [see Warnings and Precautions (5.4)]. Alternatively, consider the use of non-opioid analgesics in these patients. 5.9Adrenal 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 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.. 5.10Severe Hypotension. Oxycodone Hydrochloride Oral Solution, USP 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 reduced blood volume or concurrent administration of certain CNS depressant drugs (e.g. phenothiazines or general anesthetics) [see Drug Interactions (7)]. Monitor these patients for signs of hypotension after initiating or titrating the dosage of Oxycodone Hydrochloride Oral Solution, USP. In patients with circulatory shock, Oxycodone Hydrochloride Oral Solution, USP may cause vasodilation that can further reduce cardiac output and blood pressure. Avoid the use of Oxycodone Hydrochloride Oral Solution, USP in patients with circulatory shock. 5.11Risks 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 CO retention (e.g., those with evidence of increased intracranial pressure or brain tumors), Oxycodone Hydrochloride Oral Solution, USP may reduce respiratory drive, and the resultant CO retention can further increase intracranial pressure. Monitor such patients for signs of sedation and respiratory depression, particularly when initiating therapy with Oxycodone Hydrochloride Oral Solution, USP.
