buprenorphine

Buprenorphine is a prescription opioid medication used primarily to treat opioid use disorder (OUD), acute pain, and chronic pain. It functions as a partial mu-opioid receptor agonist and a kappa-opioid receptor antagonist. This unique pharmacology allows it to satisfy opioid cravings and prevent withdrawal symptoms without producing the intense euphoria or dangerous respiratory depression associated with full opioids like heroin, fentanyl, or oxycodone • Sublingual Tablets / Buccal Films: Dissolved completely under the tongue or inside the cheek. For OUD, it is frequently combined with naloxone—an opioid antagonist—under brand names like Suboxone or Zubsolv. Naloxone remains inactive if taken as directed but triggers severe withdrawal if crushed and injected, which directly discourages misuse.

• Long-Acting Injections: Subcutaneous injections given weekly or monthly under brand names like Sublocade or Brixadi.

• Transdermal Patches: Extended-release skin patches, such as Butrans, which provide continuous pain relief over a seven-day period
