Quizplus · Accepted Answer

Methadone is used in maintenance therapy as a substitute for opioids to prevent withdrawal symptoms and reduce cravings. Its effectiveness in reducing the urge to take drugs is due to its ability to occupy the same brain receptors as other opioids, without producing the same high, effectively blocking the effects of other opioids. This is known as a blocking dose of methadone.
