Suboxone is a medication that combines two active ingredients: buprenorphine and naloxone. Buprenorphine is a partial opioid agonist, which means it binds to the same receptors in the brain as opioids but produces less of a euphoric effect. Naloxone is an opioid antagonist, which helps to block the effects of opioids and prevent misuse. Together, these two ingredients work to reduce cravings and withdrawal symptoms, making it easier for individuals to abstain from opioid use.
