How does Naltrexone aid in treating opioid addiction?

Naltrexone plays a crucial role in treating opioid addiction by blocking the opioid receptors in the brain. This action prevents opioids from exerting their effects, effectively reducing cravings for these substances. When an individual is on Naltrexone, if they attempt to use opioids, they will not experience the euphoric effects that may have contributed to their addiction, thus helping to deter relapse. By reducing both the subjective high from opioids and the cravings that accompany opioid dependence, Naltrexone can support individuals in maintaining sobriety and aid in their recovery process.

The other options do not accurately describe the function of Naltrexone. For instance, enhancing opioid effects contradicts the medication’s purpose of blocking receptors. Similarly, increasing the risk of overdose is not characteristic of Naltrexone, as it is designed to protect against the sedative effects of opioids and mitigate the potential for misuse. Lastly, Naltrexone does not act as a sedative; instead, it maintains non-sedative effects that support individuals in their treatment journey.
