What is one of the main functions of Naltrexone?

• A. To enhance the effect of opioids
• B. To block opioids from binding to receptors
• C. To increase craving for alcohol
• D. To act as a sedative

Answer: (B)

Naltrexone serves a crucial function in the treatment of opioid dependence and alcohol use disorders by blocking opioids from binding to their receptors in the brain. This mechanism mitigates the euphoric effects that opioids typically provide, thereby reducing the incentive to use these substances. By occupying the opioid receptors without activating them, Naltrexone effectively prevents the desired effects of opioids, thereby aiding individuals in their recovery efforts. Furthermore, its role extends beyond opioid use disorder; it is also employed in managing alcohol use disorder by diminishing the reinforcing effects of alcohol, thus helping reduce cravings and the likelihood of relapse. This blocking action is central to its use as a therapeutic agent in addiction treatment.
