Quizplus · Accepted Answer

Naltrexone and naloxone are opioid antagonists that block the effects of opioids on the brain. They have been used to reduce the reinforcing effects of alcohol and heroin, as they bind to opioid receptors in the brain and prevent the release of dopamine, which is the neurotransmitter that contributes to the rewarding effects of substance use. Naltrexone has also been used to reduce alcohol cravings, while naloxone is used as an emergency treatment for opioid overdose.
