What is Belbuca? How do Belbuca Strips Work?

By Daisy Duddy

What is Belbuca?

Belbuca is the brand name for buprenorphine-monotherapy buccal film. The term “buccal film” simply refers to the route of administration. Buprenorphine can be taken several different ways including buccal film, sublingual film, sublingual tablet, injection, or implant.

Belbuca strips are placed on the inside of your mouth on the inner wall of your cheek. Buccal films are designed to dissolve directly through your cheek. When administered through buccal film, buprenorphine-monotherapy (Belbuca) is effective for approximately 27 hours

Some MOUD’s, like Suboxone or Zubsolv, combine buprenorphine and naloxone. In contrast, Belbuca is a buprenorphine-monotherapy which means it does not combine ingredients. Belbuca is strictly composed of buprenorphine. To fully understand how Belbuca works, we need to understand how buprenorphine works. 

How does Belbuca work?

Buprenorphine is one of the three FDA-approved medications used to treat OUD. It is available in a variety of forms including as a buccal film, sublingual film or tablet, injection, or implant.

Buprenorphine is known as a partial opioid agonist. A partial opioid agonist helps to reduce opioid cravings and withdrawal symptoms in individuals with OUD. It does this by interacting with the same opioid receptors that are activated by full opioid agonists. Examples of a full opioid agonist include oxycodone, heroin, fentanyl, and methadone.

Unlike a full agonist, buprenorphine does not fully activate the opioid receptors. Buprenorphine has a “ceiling effect” because it only partially activates opioid receptors. It is nearly impossible for those with OUD to get “high” or experience euphoric effects with buprenorphine. Buprenorphine is a maintenance medication that can be used temporarily or as a long-term treatment for patients with OUD. 

What are Medications for Opioid Use Disorder?

Medications for opioid use disorder (MOUD) are a critical tool for individuals struggling with opioids. Research has repeatedly shown the efficacy of this pharmacological component. To date, there are three medications that are recommended by the World Health Organization (WHO) and approved by the US Food and Drug Administration (FDA) to treat opioid use disorder (OUD): methadone, buprenorphine, and naltrexone. All brand name MOUD prescriptions include one, or a combination, of these three medications. Common brand names include Bunavail, Belbuca, Subutex, Suboxone, Naltrexone (Vivitrol), Sublocade, and ZubSolve. There are unique characteristics and side effects associated with each medication. This page focuses specifically on the brand name Belbuca
