Treatment of opioid use disorder (OUD) with buprenorphine helps people curb cravings enough so that they can achieve their goals, including learning how to change their behavior and rebuilding their life. It is very common for someone who has a moderate to severe addiction to be experiencing additional personal, financial, and physical issues. Additionally, there is a high risk of overdose when using opioids. Treatment of OUD with buprenorphine reduces the risk of fatal overdose.
When you take opioids, the opioid receptor is activated in your brain (there are opioid receptors in the cortex, limbic system, and brain stem), resulting in the pleasurable feelings and pain relief associated with these drugs. It also results in a slowing, or depression, of the central nervous system that can cause you to stop breathing, which is what happens during an overdose.
