Description
Buprenorphine sublingual tablet is uncoated, round, biconvex, white to off-white tablet. It contains buprenorphine hydrochloride USP, a partial agonist at the mu-opioid receptor, and is available in two dosage strengths, 2 mg buprenorphine and 8 mg buprenorphine (as the free base, equivalent to 2.16 mg buprenorphine hydrochloride USP and 8.64 mg buprenorphine hydrochloride USP). Each tablet also contains lactose monohydrate, mannitol, povidone, anhydrous citric acid, sodium citrate, butylated hydroxyanisole, corn starch, pregelatinized starch, and magnesium stearate. Chemically, buprenorphine hydrochloride is (2S)-2-[17-Cyclopropylmethyl-4,5α-epoxy-3-hydroxy-6-methoxy-6α,14-ethano-14α-morphinan-7α-yl]-3,3-dimethylbutan-2-ol hydrochloride. It has the following chemical structure: [buprenorphine-str] Buprenorphine hydrochloride, USP has the molecular formula C29H41NO4
What Is Buprenorphine Sublingual Used For?
Buprenorphine sublingual tablet is indicated for the treatment of opioid dependence and is preferred for induction. Buprenorphine sublingual tablet should be used as part of a complete treatment plan to include counseling and psychosocial support.
Dosage and Administration
2.1 Important Dosage and Administration Instructions Buprenorphine sublingual tablet is administered sublingually as a single daily dose. Buprenorphine sublingual tablet does not contain naloxone and is preferred for use only during induction. Following induction, buprenorphine and naloxone sublingual film or buprenorphine and naloxone sublingual tablet is preferred due to the presence of naloxone when clinical use includes unsupervised administration. The use of buprenorphine sublingual tablet for unsupervised administration should be limited to those patients who cannot tolerate buprenorphine and naloxone sublingual film or buprenorphine and naloxone sublingual tablet; for example, those patients who have been shown to be hypersensitive to naloxone. Medication should be prescribed in consideration of the frequency of visits. Provision of multiple refills is not advised early in treatment or without appropriate patient follow-up visits. 2.2 Patient Access to Naloxone for the Emergency Treatment of Opioid Overdose Discuss the availability of naloxone for the emergency treatment of opioid overdose with the patient and caregiver. Because patients being treated for opioid use disorder have the potential for relapse, putting them at risk for opioid overdose, strongly consider prescribing naloxone for the emergency treatment of opioid overdose, both when initiating and renewing treatment with buprenorphine sublingual tablet. Also consider prescribing naloxone if the patient has household members (including children) or other close contacts at risk for accidental ingestion or opioid overdose [see Warnings and Precautions (5.2)]. Advise patients and caregivers that naloxone may also be administered for a known or suspected overdose with buprenorphine sublingual tablet itself. Higher than normal doses and repeated administration of naloxone may be necessary due to the long duration of action of buprenorphine sublingual tablet and its affinity for the mu-opioid receptor [see Overdosage (10)]. Inform patients and caregivers of their options for obtaining naloxone as permitted by individual state naloxone dispensing and prescribing requirements or guidelines (e.g., by prescription, directly from a pharmacist, or as part of a community-based program) [see Patient Counseling Information (17)]. 2.3 Induction Prior to induction, consideration should be given to the type of opioid dependence (i.e., long- or short-acting opioid products), the time since last opioid use, and the degree or level of opioid dependence. Patients dependent on heroin or other short-acting opioid products: At treatment initiation, the first dose of buprenorphine sublingual tablet should be administered only when objective and clear signs of moderate opioid withdrawal appear, and not less than 4 hours after the patient last used an opioid. It is recommended that an adequate treatment dose, titrated to clinical effectiveness, should be achieved as rapidly as possible. The dosing on the...
Side Effects (Adverse Reactions)
The following serious adverse reactions are described elsewhere in the labeling:
Drug Interactions
Table 3 includes clinically significant drug interactions with buprenorphine. Table 3. Clinically Significant Drug Interactions Benzodiazepines or other Central Nervous System (CNS) Depressants Clinical Impact: Due to additive pharmacologic effects, the concomitant use of benzodiazepines or other CNS depressants, including alcohol, increases the risk of respiratory depression, profound sedation, coma, and death. Intervention: 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 CNS depressant or decreasing to the lowest effective dose may be appropriate. Before co-prescribing benzodiazepines for anxiety or insomnia, ensure that patients are appropriately diagnosed and consider alternative medications and non-pharmacologic treatments [see Warnings and Precautions (5.2, 5.3)]. If concomitant use is warranted, strongly consider prescribing naloxone for the emergency treatment of opioid overdose, as is recommended for all patients in treatment for opioid use disorder [see Warnings and Precautions (5.2)]. Examples: Alcohol, benzodiazepines and other sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, and other opioids. Inhibitors of CYP3A4 Clinical Impact: 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 is achieved. After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, the buprenorphine plasma concentration will decrease [see Clinical Pharmacology (12.3)], potentially resulting in decreased opioid efficacy or a withdrawal syndrome in patients who had developed physical dependence to buprenorphine. Intervention: If concomitant use is necessary, consider dosage reduction of buprenorphine 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 dosage until stable drug effects are achieved. Monitor for signs of opioid withdrawal. Examples: Macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g. ketoconazole), protease inhibitors (e.g., ritonavir) CYP3A4 Inducers Clinical Impact: The concomitant use of buprenorphine and CYP3A4 inducers can decrease the plasma concentration of buprenorphine [see Clinical Pharmacology (12.3)], potentially resulting in decreased efficacy or onset of a withdrawal syndrome in patients who have developed physical dependence to buprenorphine. After stopping a CYP3A4 inducer, as the effects of the inducer decline, the buprenorphine plasma concentration will increase [see Clinical Pharmacology (12.3)],...
Contraindications
Buprenorphine sublingual tablet is contraindicated in patients with a history of hypersensitivity to buprenorphine, as serious adverse reactions, including anaphylactic shock, have been reported [see Warnings and Precautions (5.9)].
Overdosage
Clinical Presentation The manifestations of acute overdose include pinpoint pupils, sedation, hypotension, hypoglycemia, respiratory depression, and death. Treatment of Overdose In the event of overdose, the respiratory and cardiac status of the patient should be monitored carefully. When respiratory or cardiac functions are depressed, primary attention should be given to the re-establishment of adequate respiratory exchange through provision of a patent airway and institution of assisted or controlled ventilation. Oxygen, IV fluids, vasopressors, and other supportive measures should be employed as indicated. In the case of overdose, the primary management should be the re-establishment of adequate ventilation with mechanical assistance of respiration, if required. Naloxone may be of value for the management of buprenorphine overdose. Higher than normal doses and repeated administration may be necessary. The long duration of action of buprenorphine sublingual tablet should be taken into consideration when determining the length of treatment and medical surveillance needed to reverse the effects of an overdose. Insufficient duration of monitoring may put patients at risk.
