Question

Quizplus · Accepted Answer

Naltrexone is an opiate antagonist that works by binding to the same receptors in the brain that heroin binds to, thereby blocking the effects of heroin and reducing cravings. Methadone and morphine are both opioid agonists, which means they activate the same receptors in the brain as heroin and can lead to dependence and addiction. Percodan is a combination of oxycodone (an opioid) and aspirin, and is also not an opiate antagonist.
