What role does naltrexone play in substance use treatment?

Naltrexone is an opioid antagonist, meaning its primary role in substance use treatment is to block the effects of opioids by binding to the same receptors in the brain that opioids would typically activate. This property helps to reduce cravings and the pleasurable effects associated with opioid use, thereby supporting individuals in their recovery from addiction.

By inhibiting the euphoric effects of opioids, naltrexone can be particularly effective in preventing relapse among individuals who are recovering from opioid use disorder. This medication is often used as part of a comprehensive treatment plan that can include counseling and other therapeutic approaches.

The other options do not accurately reflect naltrexone's role. It does not enhance the effects of opioids, serve specifically as a pain management solution, or encourage opioid use, which aligns with the understanding of naltrexone as a medication focused on promoting recovery and reducing the potential for drug misuse.
