action of methadone1
Action of Methadone
  • There are two major affects from blocking these receptors:
  • 1. Methadone will block these receptors for up to 24 hours and even if a person addicted to heroin takes heroin after taking methadone, the person will not feel the same effects of the heroin that he or she has felt before.
