Suboxone is a medication used to treat opioid addiction. It contains buprenorphine and naloxone, which work together to reduce withdrawal symptoms and cravings. Buprenorphine is a partial opioid agonist, meaning it activates the same receptors in the brain as opioids but to a lesser extent. Naloxone blocks the effects of opioids and reduces the risk of misuse. Together, they help individuals manage their addiction and reduce the risk of relapse.
