Avoid concomitant use of buprenorphine transdermal system with a full opioid agonist analgesic.
Advise patients and their caregivers to avoid exposing the buprenorphine transdermal system application site and surrounding area to direct external heat sources, such as heating pads or electric blankets, heat or tanning lamps, saunas, hot tubs, and heated water beds while wearing the system because an increase in absorption of buprenorphine may occur [see Clinical Pharmacology Advise patients against exposure of the buprenorphine transdermal system application site and surrounding area to hot water or prolonged exposure to direct sunlight.
There is a potential for temperature-dependent increases in buprenorphine released from the system resulting in possible overdose and death [see Patient Counseling Information 17 ].
Monitor patients wearing buprenorphine transdermal systems who develop fever or increased core body temperature due to strenuous exertion for opioid side effects and adjust the buprenorphine transdermal system dose if signs of respiratory or central nervous system depression occur. Buprenorphine transdermal system is contraindicated in patients with known or suspected gastrointestinal obstruction, including paralytic ileus.
The buprenorphine in buprenorphine transdermal system may cause spasm of the sphincter of Oddi. Opioids may cause increases in the serum amylase. Monitor patients with biliary tract disease, including acute pancreatitis, for worsening symptoms.
The buprenorphine in buprenorphine transdermal system may increase the frequency of seizures in patients with seizure disorders, and may increase the risk of seizures in other clinical settings associated with seizures. Monitor patients with a history of seizure disorders for worsened seizure control during buprenorphine transdermal system therapy. Buprenorphine transdermal system may impair the mental and physical abilities needed to perform potentially hazardous activities such as driving a car or operating machinery.
Warn patients not to drive or. Buprenorphine transdermal system has not been studied and is not approved for use in the management of addictive disorders. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
A total of 5, patients were treated with buprenorphine transdermal system in controlled and open-label chronic pain clinical trials. Nine hundred twenty-four subjects were treated for approximately six months and subjects were treated for approximately one year. The clinical trial population consisted of patients with persistent moderate to severe pain. The following table lists adverse reactions that were reported in at least 2. Gastrointestinal disorders : diarrhea, dyspepsia, and upper abdominal pain.
General disorders and administration site conditions : fatigue, peripheral edema, application site irritation, pain, pyrexia, chest pain, and asthenia. Infections and infestations : urinary tract infection, upper respiratory tract infection, nasopharyngitis, influenza, sinusitis, and bronchitis. Musculoskeletal and connective tissue disorders : back pain, arthralgia, pain in extremity, muscle spasms, musculoskeletal pain, joint swelling, neck pain, and myalgia.
Nervous system disorders : hypoesthesia, tremor, migraine, and paresthesia. Respiratory, thoracic and mediastinal disorders : dyspnea, pharyngolaryngeal pain, and cough. Skin and subcutaneous tissue disorders : pruritus, hyperhidrosis, rash, and generalized pruritus.
Abdominal distention, abdominal pain, accidental injury, affect lability, agitation, alanine aminotransferase increased, angina pectoris, angioedema, apathy, application site dermatitis, asthma aggravated, bradycardia, chills, confusional state, contact dermatitis, coordination abnormal, dehydration, depersonalization, depressed level of consciousness, depressed mood, disorientation, disturbance in attention, diverticulitis, drug hypersensitivity, drug withdrawal syndrome, dry eye, dry skin, dysarthria, dysgeusia, dysphagia, euphoric mood, face edema, flatulence, flushing, gait disturbance, hallucination, hiccups, hot flush, hyperventilation,.
The following adverse reactions have been identified during post approval use of buprenorphine. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Serotonin syndrome : Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during concomitant use of opioids with serotonergic drugs.
Adrenal insufficiency : Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. Anaphylaxis : Anaphylaxis has been reported with ingredients contained in buprenorphine transdermal system. Androgen deficiency : Cases of androgen deficiency have occurred with chronic use of opioids [see Clinical Pharmacology Table 5 Includes clinically significant drug interactions with buprenorphine transdermal system.
There have been a number of reports regarding coma and death associated with the misuse and abuse of the combination of buprenorphine and benzodiazepines. In many, but not all of these cases, buprenorphine was misused by self-injection of crushed buprenorphine tablets.
Preclinical studies have shown that the combination of benzodiazepines and buprenorphine altered the usual ceiling effect on buprenorphine-induced respiratory depression, making the respiratory effects of buprenorphine appear similar to those of full opioid agonists. Closely monitor patients with concurrent use of buprenorphine transdermal system and benzodiazepines. Warn patients that it is extremely dangerous to self-administer benzodiazepines while taking buprenorphine transdermal system, and warn patients to use benzodiazepines concurrently with buprenorphine transdermal system only as directed by their physician.
Due to additive pharmacologic effects, the concomitant use of benzodiazepines or other CNS depressants, including alcohol, can increase the risk of hypotension, respiratory depression, profound sedation, coma, and death.
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. The concomitant use of buprenorphine and CYP3A4 inhibitors can increase the plasma concentration of buprenorphine, resulting in increased or prolonged opioid effects, particularly when an inhibitor is added after a stable dose of buprenorphine transdermal system is achieved.
After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, the buprenorphine plasma concentration will decrease [see Clinical Pharmacology If concomitant use is necessary, consider dosage reduction of buprenorphine transdermal system until stable drug effects are achieved. Monitor patients for respiratory depression and sedation at frequent intervals.
If a CYP3A4 inhibitor is discontinued, consider increasing the buprenorphine transdermal system dosage until stable drug effects are achieved.
Monitor for signs of opioid withdrawal. The concomitant use of buprenorphine and CYP3A4 inducers can decrease the plasma concentration of buprenorphine [see Clinical Pharmacology After stopping a CYP3A4 inducer, as the effects of the inducer decline, the buprenorphine plasma concentration will increase [see Clinical Pharmacology If concomitant use is necessary, consider increasing the buprenorphine transdermal system dosage until stable drug effects are achieved.
If a CYP3A4 inducer is discontinued, consider buprenorphine transdermal system dosage reduction and monitor for signs of respiratory depression. The concomitant use of opioids with other drugs that affect the serotonergic neurotransmitter system has resulted in serotonin syndrome.
If concomitant use is warranted, carefully observe the patient, particularly during treatment initiation and dose adjustment. MAOI interactions with opioids may manifest as serotonin syndrome or opioid toxicity e. The use of buprenorphine transdermal system is not recommended for patients taking MAOIs or within 14 days of stopping such treatment.
Due to the risk of respiratory depression with concomitant use of skeletal muscle relaxants and opioids, consider prescribing naloxone for the emergency treatment of opioid overdose [see Dosage and Administration 2. Monitor patients for signs of urinary retention or reduced gastric motility when buprenorphine transdermal system is used concomitantly with anticholinergic drugs.
Prolonged use of opioid analgesics during pregnancy may cause neonatal opioid withdrawal syndrome [see Warnings and Precautions 5. Available data with buprenorphine transdermal system in pregnant women are insufficient to inform a drug-associated risk for major birth defects and miscarriage. Based on animal data, advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.
In the U. Prolonged 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. Opioids cross the placenta and may produce respiratory depression in neonates. An opioid antagonist such as naloxone must be available for reversal of opioid-induced respiratory depression in the neonate.
Buprenorphine transdermal system is not recommended for use in women immediately prior to labor, when shorter acting analgesics or other analgesic techniques are more appropriate. Opioid analgesics, including buprenorphine transdermal system, can prolong labor through actions that 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.
Studies in rats and rabbits demonstrated no evidence of teratogenicity following buprenorphine transdermal system or subcutaneous SC administration of buprenorphine during the period of organogenesis.
No teratogenicity was observed at any dose. In a pre- and post-natal study conducted in pregnant and lactating rats, administration of buprenorphine either as buprenorphine transdermal system or SC buprenorphine was associated with toxicity to offspring. Buprenorphine was present in maternal milk. Administration of buprenorphine transdermal system or SC buprenorphine at 0. Because of the potential for serious adverse reactions, including excess sedation and respiratory depression in a breastfed infant, advise patients that breastfeeding is not recommended during treatment with buprenorphine transdermal system.
Monitor infants exposed to buprenorphine transdermal system through breast milk for excess sedation and respiratory depression. Withdrawal symptoms can occur in breastfed infants when maternal administration of buprenorphine is stopped or when breast-feeding is stopped.
Chronic 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. The safety and efficacy of buprenorphine transdermal system in patients under 18 years of age has not been established. Buprenorphine transdermal system has been evaluated in an open-label clinical trial in pediatric patients. However, definitive conclusions are not possible because of the small sample size.
Of the total number of subjects in the clinical trials 5, , buprenorphine transdermal system was administered to 1, patients aged 65 years and older. Of those, patients were 75 years of age and older. In the clinical program, the incidences of selected buprenorphine transdermal system-related AEs were higher in older subjects.
In a separate dose-escalation safety study, the pharmacokinetics in the healthy elderly and hypertensive elderly subjects taking thiazide diuretics were similar to those in the healthy young adults. In the elderly groups evaluated, adverse event rates were similar to or lower than rates in healthy young adult subjects, except for constipation and urinary retention, which were more common in the elderly.
Although specific dose adjustments on the basis of advanced age are not required for pharmacokinetic reasons, use caution in the elderly population to ensure safe use [see Clinical Pharmacology 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 buprenorphine transdermal system slowly in geriatric patients and monitor closely for signs of central nervous system and respiratory depression [see Warnings and Precautions 5.
In a study utilizing intravenous buprenorphine, peak plasma levels C max and exposure AUC of buprenorphine in patients with mild and moderate hepatic impairment did not increase as compared to those observed in subjects with normal hepatic function.
As buprenorphine transdermal system is intended for 7-day dosing, consider the use of alternate analgesic therapy in patients with severe hepatic impairment [see Dosage and Administration 2. Buprenorphine transdermal system contains buprenorphine, a Schedule III controlled substance with an abuse potential similar to other Schedule III opioids. Buprenorphine transdermal system can be abused and is subject to misuse, addiction and criminal diversion [see Warnings and Precautions 5.
The high drug content in extended-release formulations adds to the risk of adverse outcomes from abuse and misuse. All patients treated with opioids, including buprenorphine transdermal system, require careful monitoring for signs of abuse and addiction, since 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 a prescription drug, even once, for its rewarding psychological or physiological effects.
Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that develop after repeated substance use and includes: a strong desire to take the drug, difficulties in controlling its use, persisting in its use despite harmful consequences, a higher priority given to drug use than to other activities and obligations, increased tolerance, and sometimes a physical withdrawal.
Preoccupation with achieving adequate pain relief can be appropriate behavior in a patient with poor pain control. Abuse and addiction are separate and distinct from physical dependence and tolerance. Healthcare 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. Buprenorphine transdermal system, 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. Buprenorphine transdermal system is intended for transdermal use only. Abuse of buprenorphine transdermal system poses a risk of overdose and death.
This risk is increased with concurrent abuse of buprenorphine transdermal system with alcohol and other substances including other opioids and benzodiazepines [see Warnings and Precautions 5. Intentional compromise of the transdermal delivery system will result in the uncontrolled delivery of buprenorphine and pose a significant risk to the abuser that could result in overdose and death [see Warnings and Precautions 5.
Abuse may occur by applying the transdermal system in the absence of legitimate purpose, or by chewing, swallowing, snorting, or injecting buprenorphine extracted from the transdermal system. Parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and HIV.
Both tolerance and physical dependence can develop during chronic opioid therapy. Tolerance 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. Tolerance may occur to both the desired and undesired effects of drugs, and may develop at different rates for different effects. Physical dependence is a physiological state in which the body adapts to the drug after a period of regular exposure, resulting in withdrawal symptoms after abrupt discontinuation or a significant dosage reduction of a drug.
Withdrawal also may be precipitated through the administration of drugs with opioid antagonist activity e. Physical dependence may not occur to a clinically significant degree until after several days to weeks of continued opioid usage. Do not abruptly discontinue buprenorphine transdermal system in a patient physically dependent on opioids.
Rapid tapering of buprenorphine transdermal system in a patient physically dependent on opioids may lead to serious withdrawal symptoms, uncontrolled pain, and suicide. When discontinuing buprenorphine transdermal system, gradually taper the dosage using a patient-specific plan that considers the following: the dose of buprenorphine transdermal system the patient has been taking, the duration of treatment, and the physical and psychological attributes of the patient. To improve the likelihood of a successful taper and minimize withdrawal symptoms, it is important that the opioid tapering schedule is agreed upon by the patient.
In patients taking opioids for a long duration at high doses, ensure that a multimodal approach to pain management, including mental health support if needed , is in place prior to initiating an opioid analgesic taper [see Dosage and Administration 2.
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. Acute overdosage with buprenorphine transdermal system is 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 due to severe hypoxia in overdose situations [see Clinical Pharmacology In case of overdose, priorities are the re-establishment of a patent and protected airway and institution of assisted or controlled ventilation, if needed. Employ other supportive measures including oxygen, vasopressors in the management of circulatory shock and pulmonary edema as indicated.
Cardiac arrest or arrhythmias will require advanced life support techniques. Opioid antagonists, such as naloxone, are specific antidotes to respiratory depression resulting from opioid overdose. However, naloxone may not be effective in reversing any respiratory depression produced by buprenorphine.
The onset of naloxone effect may be delayed by 30 minutes or more. Doxapram hydrochloride a respiratory stimulant has also been used. Remove buprenorphine transdermal system immediately. Because the duration of reversal would be expected to be less than the duration of action of buprenorphine from buprenorphine transdermal system, carefully monitor the patient until spontaneous respiration is reliably re-established.
Even in the face of improvement, continued medical monitoring is required because of the possibility of extended effects as buprenorphine continues to be absorbed from the skin. Due to this long apparent terminal half-life, patients may require monitoring and treatment for at least 24 hours. In an individual physically dependent on opioids, administration of an opioid receptor antagonist may precipitate an acute withdrawal syndrome. The severity of the withdrawal symptoms experienced will depend on the degree of physical dependence and the dose of the antagonist administered.
If a decision is made to treat serious respiratory depression in the physically dependent patient, administration of the antagonist should be begun with care and by titration with smaller than usual doses of the antagonist. Buprenorphine transdermal system is a transdermal system providing systemic delivery of buprenorphine, a mu opioid partial agonist analgesic, continuously for 7 days.
The structural formula is:. The molecular weight of buprenorphine is Buprenorphine occurs as a white or almost white powder and is very slightly soluble in water, freely soluble in acetone, soluble in methanol and ether, and slightly soluble in cyclohexane.
The pKa is 8. Five different strengths of buprenorphine transdermal system are available: 5, 7. The proportion of buprenorphine mixed in the adhesive matrix is the same in each of the five strengths. The amount of buprenorphine released from each system per hour is proportional to the active surface area of the system.
The skin is the limiting barrier to diffusion from the system into the bloodstream. Proceeding from the outer surface toward the surface adhering to the skin, the layers are 1 a beige-colored web backing layer; 2 an adhesive rim without buprenorphine; 3 a separating layer over the buprenorphine-containing adhesive matrix; 4 the buprenorphine-containing adhesive matrix; and 5 a peel-off release liner.
Before use, the release liner covering the adhesive layer is removed and discarded. The active ingredient in buprenorphine transdermal system is buprenorphine. The inactive ingredients in each system are: acrylic adhesive, levulinic acid, oleyl oleate, and povidone.
