Overview

What is BUNAVAIL?

BUNAVAIL (buprenorphine and naloxone buccal film) is a citrus flavored oral transmucosal form of buprenorphine, an opioid partial agonist, and naloxone, an opioid antagonist, intended for application to the buccal mucosa. Each dose unit is a yellow rectangular film, with ink marking on the mucoadhesive side. The film adheres upon contact with the moist buccal mucosa. BUNAVAIL contains buprenorphine HCl, a mu-opioid receptor partial agonist and a kappa-opioid receptor antagonist, and naloxone HCl dihydrate, an opioid receptor antagonist, at a ratio of ~6:1 (ratio of free bases). It is available in three strengths: 2.1 mg buprenorphine with 0.3 mg naloxone in a 2.2 cm film; 4.2 mg buprenorphine with 0.7 mg naloxone in a 4.4 cm film; and 6.3 mg buprenorphine with 1 mg naloxone in a 6.5 cm film. Each film also contains carboxymethylcellulose sodium, citric acid, citrus blend flavor, dibasic sodium phosphate, blue ink, hydroxyethyl cellulose, hydroxypropyl cellulose, methylparaben, monobasic sodium phosphate, polycarbophil, propylene glycol, propylparaben, yellow iron oxide, sodium benzoate, sodium hydroxide, sodium saccharin, vitamin E acetate, and purified water. The blue ink contains FD&C Blue No.1, ethanol, purified shellac, acetone, ammonium hydroxide and water.

Chemically, buprenorphine HCl, USP is 6,14-Ethenomorphinan-7-methanol, 17-(cyclopropyl-methyl)-α-(1,1-dimethylethyl)-4,5-epoxy-18,19-dihydro-3-hydroxy-6-methoxy-α-methyl-, hydrochloride, [5α,7α()]. It has the following chemical structure:

Buprenorphine HCl has the molecular formula CHNO ∙ HCl and the molecular weight is 504.10. It is a white or off-white crystalline powder, sparingly soluble in water, freely soluble in methanol, soluble in alcohol, and practically insoluble in cyclohexane.

Chemically, naloxone HCl dihydrate, USP is morphinan-6-one, 4,5-epoxy-3,14-dihydroxy-17-(2-propenyl)-, hydrochloride, (5α)-, dihydrate. It has the following chemical structure:

Naloxone hydrochloride dihydrate has the molecular formula CHNO ∙ HCl ∙ 2HO and the molecular weight is 399.87. It is a white to slightly off-white powder, and is freely soluble in water, soluble in alcohol, and practically insoluble in toluene and ether.

Clinical Information

Chemical Structure

Clinical Pharmacology

BUNAVAIL contains buprenorphine and naloxone. Buprenorphine is a partial agonist at the mu-opioid receptor and an antagonist at the kappa-opioid receptor. Naloxone is a potent antagonist at mu-opioid receptors and produces opioid withdrawal signs and symptoms, if administered parenterally, in individuals physically dependent on full opioid agonists.

Non-Clinical Toxicology
BUNAVAIL is contraindicated in patients with a history of hypersensitivity to buprenorphine or naloxone as serious adverse reactions, including anaphylactic shock, have been reported .

Inhibitors of CYP3A4 and CYP2D6

After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, the oxycodone plasma concentration will decrease [see ], resulting in decreased opioid efficacy or a withdrawal syndrome in patients who had developed physical dependence to Oxycodone and Acetaminophen Tablets.

If concomitant use is necessary, consider dosage reduction of Oxycodone and Acetaminophen Tablets 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 Oxycodone and Acetaminophen Tablets dosage until stable drug effects are achieved. Monitor for signs of opioid withdrawal.





After stopping a CYP3A4 inducer, as the effects of the inducer decline, the oxycodone plasma concentration will increase [see ], which could increase or prolong both the therapeutic effects and adverse reactions, and may cause serious respiratory depression.

If concomitant use is necessary, consider increasing the Oxycodone and Acetaminophen Tablets dosage until stable drug effects are achieved. Monitor for signs of opioid withdrawal. If a CYP3A4 inducer is discontinued, consider Oxycodone and Acetaminophen Tablets dosage reduction and monitor for signs of respiratory depression.

Benzodiazepines and Other CNS Depressants

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 ].

Serotonergic Drugs

If concomitant use is warranted, carefully observe the patient, particularly during treatment initiation and dose adjustment. Discontinue Oxycodone and Acetaminophen Tablets if serotonin syndrome is suspected.

Monoamine Oxidase Inhibitors (MAOIs)

The use of Oxycodone and Acetaminophen Tablets 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.

Mixed Agonist/Antagonist and Partial Agonist Opioid Analgesics

Advise patient to avoid concomitant use of these drugs.

Muscle Relaxants

If concomitant use is warranted, monitor patients for signs of respiratory depression that may be greater than otherwise expected and decrease the dosage of Oxycodone and Acetaminophen Tablets and/or the muscle relaxant as necessary.

Diuretics

If concomitant use is warranted, monitor patients for signs of diminished diuresis and/or effects on blood pressure and increase the dosage of the diuretic as needed.

Anticholinergic Drugs

If concomitant use is warranted, monitor patients for signs of urinary retention or reduced gastric motility when Oxycodone and Acetaminophen Tablets are used concomitantly with anticholinergic drugs.

BUNAVAIL contains buprenorphine, a Schedule III controlled substance that can be abused in a manner similar to other opioids, legal or illicit. Prescribe and dispense buprenorphine with appropriate precautions to minimize risk of misuse, abuse, or diversion, and ensure appropriate protection from theft, including in the home. Clinical monitoring appropriate to the patient's level of stability is essential. Multiple refills should not be prescribed early in treatment or without appropriate patient follow-up visits .
