-
Cassipa
- Used after induction and stabilization of the patient, and after buprenorphine dose titrated to 16 mg using another marketed product
- If dose needs adjustment in order to maintain treatment and suppress opioid withdrawal signs and symptoms, a different product will be needed; Cassipa comes in a single dose and cannot be adjusted (ie, SL film available only as 16 mg buprenorphine/4 mg naloxone)

- Renal failure: Unknown
Dosing Considerations
Prior to induction, consideration should be given to the type of opioid dependence (ie, long- or short-acting opioid products, the time since last opioid use, and the degree or level of opioid dependence
To avoid precipitating an opioid withdrawal syndrome, the first dose of buprenorphine/naloxone should be administered only when objective and clear signs of moderate withdrawal are evident, and divided doses should be used
It is recommended that an adequate treatment dose, titrated to clinical effectiveness, be achieved as rapidly as possible
Patients dependent on methadone or long-acting opioid products may be more susceptible to precipitated and prolonged withdrawal during induction than those on short-acting opioid products; buprenorphine monotherapy is recommended in patients taking long-acting opioids instead of buprenorphine/naloxone, which may worsen withdrawal symptoms
Patients dependent on heroin or other short-acting opioid products may be induced with buprenorphine/naloxone or with SL buprenorphine monotherapy

Access to naloxone for opioid overdose
- Assess need for naloxone upon initiating and renewing treatment
-
Consider prescribing naloxone
- Based on patient’s risk factors for overdose (eg, concomitant use of CNS depressants, a history of opioid use disorder, prior opioid overdose); presence of risk factors should not prevent proper pain management
- Household members (including children) or other close contacts at risk for accidental ingestion or overdose
-
Consult patients and caregivers on the following:
- Availability of naloxone for emergency treatment of opioid overdose
- Ways differ on how to obtain naloxone as permitted by individual state dispensing and prescribing requirements or guidelines (eg, by prescription, directly from a pharmacist, as part of a community-based program)

Cautions
Significant respiratory depression may occur with therapeutic doses
Use with caution in hypothyroidism, preexisting respiratory compromise, obstructive pulmonary disease, cor pulmonale, decreased respiratory reserve and kyphoscoliosis, myxedema, adrenocortical insufficiency, alcohol intoxication, alcohol withdrawal syndrome, coma, severe renal impairment, geriatric or debilitated patients, delirium tremens, toxic psychoses, kyphoscoliosis, prostatic hypertrophy, urethral stricture, comatose patients, central nervous system (CNS) depression, biliary tract dysfunction, severe hepatic impairment, head injury, intracranial lesions, and intracranial hypertension or conditions in which intracranial pressure (ICP) may be increased
Use caution with concurrent use of other CNS depressants
Respiratory sedation is dose-dependent; usual doses may depress respiration to same degree as 10 mg of parenteral morphine
Opioids can cause sleep-related breathing disorders including central sleep apnea (CSA) and sleep-related hypoxemia; opioid use increases risk of CSA in a dose-dependent fashion; in patients who present with CSA, consider decreasing opioid dosage using best practices for opioid taper
Use caution in patients with history of ileus or bowel obstruction
May cause orthostatic hypotension; use caution in patients with hypovolemia, cardiovascular disease, or drugs that may worsen hypertension
Effects in CNS depression may impair ability to perform tasks that require mental alertness
Life-threatening neonatal syndrome may occur in newborns following maternal exposure to opioids; treat according to protocols developed by neonatology experts; prescribers should discuss with patients importance and benefits of management of opioid addiction throughout pregnancy
Chronic use of opioids may cause reduced fertility in females and males of reproductive potential; unknown whether effects on fertility are reversible
Use caution when switching between formulations; certain sublingual film strengths may have greater bioavailability compared to the same strength of sublingual tablet; monitor for overdosing or underdosing when switching formulations
Buprenorphine may precipitate acute narcotic withdrawal in opioid-dependent patients upon rapid discontinuation or rapid taper; taper dose gradually when discontinuing therapy
Because it contains naloxone, drug is highly likely to produce marked and intense withdrawal signs and symptoms if misused parenterally by individual dependent on full opioid agonists such as heroin, morphine, or methadone
May obscure diagnosis or clinical course of patients with acute abdominal conditions
Cases of adrenal insufficiency reported with opioid use, more often following greater than one month of use; symptoms may include nausea, vomiting, anorexia, fatigue, weakness, dizziness, and low blood pressure; if adrenal insufficiency is diagnosed, treat with physiologic replacement doses of corticosteroids; wean patient off of 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 a different opioid without recurrence of adrenal insufficiency
Advise pregnant women receiving opioid addiction treatment with sublingual film of risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available
Due to risk of respiratory depression with concomitant use of skeletal muscle relaxants and opioids, consider prescribing naloxone for the emergency treatment of opioid overdose
Drug can be abused in a manner similar to other opioids; consider this when prescribing or dispensing buprenorphine in situations when clinician is concerned about increased risk of misuse, abuse, or diversion
QTc prolongation
- Thorough QT studies with buprenorphine products have demonstrated QT prolongation less than or equal to 15 msec; this QTc prolongation effect does not appear to be mediated by hERG channels; based on these two findings, buprenorphine is unlikely to be pro-arrhythmic when used alone in patients without risk factors; the risk of combining buprenorphine with other QT-prolonging agents is not known
- Consider these observations in clinical decisions when prescribing this medication to patients with risk factors such as hypokalemia, bradycardia, recent conversion from atrial fibrillation, congestive heart failure, digitalis therapy, baseline QT prolongation, subclinical long-QT syndrome, or severe hypomagnesemia
Increased risk of dental problems
- On January 12, 2022, FDA warned of potential dental problems associated with transmucosal buprenorphine-containing products (eg, buccal, sublingual)
- Cases of dental caries, some severe (eg, tooth fracture, tooth loss), reported following use of transmucosal buprenorphine-containing products; reported events include cavities, tooth decay, dental abscesses/infection, rampant caries, tooth erosion, fillings falling out, and, in some cases, total tooth loss
- Treatment for these events included tooth extraction, root canal, dental surgery, as well as other restorative procedures (eg, fillings, crowns, implants, dentures); multiple cases were reported in individuals without any prior history of dental problems
- Despite these risks, buprenorphine is an important treatment option for opioid use disorder and pain, and the benefits of these medicines clearly outweigh the risks
- Review patient’s health before initiating with transmucosal buprenorphine
- Refer patients to dental care services and encourage them to have regular dental checkups while receiving therapy; educate patients to seek dental care and strategies to maintain or improve oral health while being treated with transmucosal buprenorphine-containing products
- Strategies include, but are not limited to, gently rinsing teeth and gums with water and then swallowing after completely dissolved in oral mucosa; advise patients to wait for at least one hour after taking drug before brushing teeth
- Counsel patients regarding potential for dental problems and importance of taking extra steps after the medicine has completely dissolved, including gently rinsing teeth and gums with water and then swallow; advise to wait at least 1 hour before brushing their teeth
- Dentists treating patients taking transmucosal buprenorphine should perform a baseline dental evaluation and caries risk assessment, establish a dental caries preventive plan, and encourage regular dental checkups
Coadministration with benzodiazepines
- Life-threating respiratory depression and death may occur; many, but not all, postmarketing reports regarding coma and death involved misuses by self-injection or were associated with concomitant use of benzodiazepines or other CNS depressants, including alcohol; warn patients of potential danger of self-administration of benzodiazepines or other CNS depressants while under treatment
- Concomitant use of buprenorphine and benzodiazepines or other CNS depressants increases risk of adverse reactions including overdose and death; medication-assisted treatment of opioid use disorder, however, should not be categorically denied to patients taking these drugs; prohibiting or creating barriers to treatment can pose an even greater risk of morbidity and mortality due to the opioid use disorder alone
- If an opioid analgesic is initiated in a patient already taking a benzodiazepine or other CNS depressant, prescribe a 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
- Develop strategies to manage use of prescribed or illicit benzodiazepines or other CNS depressants at initiation of buprenorphine treatment, or if it emerges as a concern during treatment; adjustments to induction procedures and additional monitoring may be required; there is no evidence to support dose limitations or arbitrary caps of buprenorphine as a strategy to address benzodiazepine use in buprenorphine-treated patients; however, if a patient is sedated at the time of buprenorphine dosing, delay or omit the buprenorphine dose if appropriate
- Cessation of benzodiazepines or other CNS depressants is preferred in most cases of concomitant use. In some cases, monitoring in a higher level of care for taper may be appropriate. In others, gradually tapering a patient off of a prescribed benzodiazepine or other CNS depressant or decreasing to the lowest effective dose may be appropriate
- Ensure that other healthcare providers prescribing benzodiazepines or other CNS depressants are aware of the patient’s buprenorphine treatment and coordinate care to minimize the risks associated with concomitant use
- If concomitant use with benzodiazepine is warranted, consider prescribing naloxone for the emergency treatment of opioid overdose
- Confirm patients are taking their medications as prescribed and are not diverting or supplementing with illicit drugs; toxicology screening should test for prescribed and illicit benzodiazepines
Patient access to naloxone for emergency treatment of opioid overdose
- Assess potential need for naloxone; consider prescribing for emergency treatment of opioid overdose
- Consult on availability and ways to obtain naloxone as permitted by individual state naloxone dispensing and prescribing requirements or guidelines
- Educate patients regarding the signs and symptoms of respiratory depression and to call 911 or seek immediate emergency medical help in the event of a known or suspected overdose
Pregnancy & Lactation
Pregnancy
Data on use of buprenorphine, one of the active ingredients are limited; however, these data do not indicate an increased risk of major malformations specifically due to buprenorphine exposure; there are limited data from randomized clinical trials in women maintained on buprenorphine that were not designed appropriately to assess the risk of major malformations; the extremely limited data on sublingual naloxone exposure in pregnancy are not sufficient to evaluate a drug associated risk; dosage adjustments of buprenorphine may be required during pregnancy, even if patient was maintained on stable dose prior to pregnancy; withdrawal signs and symptoms should be monitored closely and dose adjusted as necessary
Neonates whose mothers have been taking opioids long term may exhibit withdrawal signs, either at birth and/or in the nursery, because they have developed physical dependence; neonatal opioid withdrawal syndrome, unlike opioid withdrawal syndrome in adults, may be life-threatening and should be treated according to protocols developed by neonatology experts
Lactation
Caution should be exercised when therapy is administered to nursing women; the developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed child from drug or from underlying maternal condition; advise breastfeeding women taking buprenorphine products to monitor infant for increased drowsiness and breathing difficulties
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Buprenorphine: Semisynthetic narcotic mixed agonist-antagonist analgesic; exerts agonistic effects at mu and delta opioid receptors in CNS, as well as antagonistic effects at kappa opioid receptor
Naloxone: Potent antagonist at mu opioid receptors and produces opioid withdrawal signs and symptoms in individuals physically dependent on full opioid agonists when administered parenterally
Absorption
Suboxone
- Peak plasma time: Buprenorphine, 1.53-1.72 hr; naloxone, 0.77-0.81 hr
- Peak plasma concentration: Buprenorphine, 0.947-3.37 ng/mL; naloxone, 54.1-193 pg/mL
Zubsolv
- Bioavailability differs from that of Suboxone
- Compared with Suboxone 8/2 mg, Zubsolv 5.7/1.4 mg provides equivalent buprenorphine exposure and 12% lower naloxone exposure
Bunavail
- Bioavailability differs from that of Suboxone
- Compared with Suboxone 8/2 mg, Bunavail 4.2/0.7 mg provides equivalent buprenorphine exposure and 33% lower naloxone exposure
- Coadministration of liquids reduced the systemic exposure up to 59% for buprenorphine and up to 76% for naloxone (depending on the pH of the liquid)
Distribution
Protein bound: Buprenorphine, 96% (primarily alpha and beta globulin); naloxone, 45% (primarily albumin)
Metabolism
Buprenorphine: Metabolized by N-dealkylation via CYP3A4 to norbuprenorphine (active metabolite) and by glucuronidation
Naloxone: Metabolized by direct glucuronidation to naloxone-3-glucuronide, as well as by N-dealkylation and reduction of 6-oxo group
Elimination
Excretion: Buprenorphine, urine (30%) and feces (69%)
Half-life
- Suboxone, Zubsolv: 24-42 hr (buprenorphine); 2-12 hr (naloxone)
- Cassipa: 35-37 hr (buprenorphine); 5.6-6.6 hr (naloxone)
- Bunavail: 16.4-27.5 hr (buprenorphine); 1.9-2.4 hr (naloxone)
Administration
Sublingual Administration
Switching between SL tablet and SL film: Potential for greater bioavailability with SL film than with generic SL tablets (monitor for over- or underdosing)
Instruct patient to rinse mouth with small volume of room-temperature water before placement of the SL film strip or tablet under their tongue
High pH beverages should be avoided prior to dosing
Place film/tablet under the tongue, close to the base on the left or right side; keep in place until completely dissolved
Advise patients not to eat or drink anything until the film is completely dissolved
Use entire tablet/film; do not chew, cut, or swallow SL or buccal preparations
Bunavail Buccal Film Application
Use the tongue to wet the inside of the cheek or rinse mouth with water to moisten the area immediately before placement
Open package immediately prior to use
Hold the buccal film with clean, dry fingers with the text (BN2, BN4, or BN6) facing up, THEN
Place the side of the film with the text (BN2, BN4, or BN6) against the inside of the cheek
Press and hold the film in place for 5 seconds
Buccal film completely dissolves after applicationInstruct the patient to avoid manipulating the film(s) with the tongue or finger(s) and avoid drinking or eating food until the film(s) dissolve
Multiple Bunavail films
- If multiple films are needed, the patient should immediately apply the next film according to the steps above
- When 2 films are required for one dose, the patient should place one film on the inside of one cheek and the other film on the inside of the other cheek
- For doses requiring multiple films, no more than 2 films should be applied to the inside of one cheek at a time
