Naltrexone is used in a case of opioid dependence to
A. Prevent respiratory depressionB. To treat withdrawal symptom
C. To prevent relapse
D. To treat overdose of opioid
The Answer is. C. (To
prevent relapse)
An overdose of opioid can be
treated with opioid antagonists (e.g., naloxone and naltrexone). Naltrexone is
an orally available opioid antagonist, which block the opioid receptors. When
an opioid-dependent person takes opioids, there are no pleasurable experiences.
Thus, he does not continue to take opioids, thereby preventing relapse.
