Buprenorphine Addiction | Definition, Symptoms and Effects
Buprenorphine is a medication derived from thebaine, an alkaloid found in the opium poppy. It is primarily used to treat opioid dependence and manage pain, offering a safer alternative to stronger opioids like heroin or methadone. In the UK, buprenorphine is a controlled substance, legally prescribed by healthcare professionals as part of opioid addiction treatment.
How is buprenorphine used to treat opioid addiction?
Buprenorphine is used in opioid addiction treatment as part of a medication-assisted therapy (MAT) approach. It works by reducing cravings and withdrawal symptoms without providing the same high that opioids like heroin or prescription painkillers deliver. Here’s how it helps:
- Partial opioid agonist: Buprenorphine is a partial opioid agonist, meaning it binds to opioid receptors in the brain but activates them less than full agonists like heroin or methadone. This reduces cravings and withdrawal symptoms while limiting the potential for abuse.
- Ceiling effect: Unlike full opioid agonists, buprenorphine has a ceiling effect, meaning that after a certain dose, taking more will not increase its effects. This makes it safer and reduces the risk of overdose.
- Stabilisation: Buprenorphine helps stabilise the patient by reducing opioid cravings and withdrawal symptoms, allowing them to focus on therapy and recovery without the constant struggle of physical dependency.
- Maintenance or detox: Buprenorphine can be used as part of a long-term maintenance plan or to gradually taper the individual off opioids entirely, depending on the treatment plan and individual needs.
