Bunavail

Generic Name: buprenorphine and naloxone
Date of Approval: June 6, 2014
Company: BioDelivery Sciences International, Inc.

Treatment for: Opioid Dependence

FDA Approves Bunavail

The U.S. Food and Drug Administration (FDA) has approved Bunavail (buprenorphine and naloxone) buccal film (CIII) for the maintenance treatment of opioid dependence as part of a complete treatment plan with counselling and psychosocial support.

Buprenorphine is a narcotic analgesic similar to morphine, and has the potential for being abused and misused. Always keep opioid medicines in a safe place to protect from theft, and out of the sight and reach of children. Naloxone is an opioid antagonist (marketed as Narcan and Evzio) used for the emergency treatment of known or suspected opioid overdose.

There are a number of buprenorphine/naloxone formulations currently available including Suboxone (tablets and sublingual film) and Zubsolv (sublingual tablets). Bunavail is a buccal formulation which sticks to the inside of the cheek, and unlike sublingual formulations which need to be kept in place until dissolved, patients can talk, swallow and go about normal daily activities while the medication is being consistently absorbed.

Bunavail can cause serious life‐threatening breathing problems, overdose and death, particularly when misused and administered via the intravenous (IV) route, or in combination with benzodiazepines, sedatives, tranquilizers or alcohol. Injecting this medicine may also cause serious withdrawal symptoms such as pain, cramps, vomiting, diarrhea, anxiety, sleep problems, and cravings.

Common side effects of Bunavail include headache, drug withdrawal syndrome, lethargy (lack of energy), sweating, constipation, decrease in sleep (insomnia), fatigue and sleepiness.

Bunavail is manufactured for BioDelivery Sciences International, Inc. in Raleigh, North Carolina.
