How Does Buprenorphine Act at Opioid Receptors?

Buprenorphine is a partial agonist at mu-opioid receptors and an antagonist at kappa-opioid receptors. Mu-receptor activity reduces opioid withdrawal symptoms and craving during opioid use disorder treatment and also produces analgesia. Its high receptor affinity and long receptor binding contribute to prolonged opioid effects and can precipitate withdrawal when started too soon after a full opioid agonist.

Which Conditions Are Treated With Buprenorphine?

Indications depend on formulation. Sublingual tablets treat opioid dependence and are preferred for induction. Extended-release subcutaneous buprenorphine treats opioid use disorder under product-specific criteria. Transdermal systems and buccal film treat severe and persistent pain requiring extended opioid therapy, while buprenorphine injection treats severe pain when alternate treatments are inadequate.

How Is Buprenorphine Used?

Administration depends on the product. Sublingual tablets are dissolved under the tongue once daily during opioid dependence treatment. Extended-release products are injected under the skin by healthcare professionals on product-specific schedules. Pain formulations include skin patches, buccal film, and intramuscular or intravenous injection. These products are not interchangeable on a dose-for-dose basis.

What Serious Risks Are Linked to Buprenorphine?

Buprenorphine can cause addiction, misuse, overdose, life-threatening respiratory depression, neonatal opioid withdrawal syndrome, low blood pressure, adrenal insufficiency, serotonin syndrome, and physical dependence. Benzodiazepines, alcohol, and other central nervous system depressants raise overdose risk. Buprenorphine products dissolved in the mouth are also linked to tooth decay, dental abscesses, tooth erosion, and tooth loss.
