Usually Subutex is given first, then the Suboxone for maintenance and further
treatment. There is no
Naloxone in Subutex.
Naloxone is an opioid antagonist and it works by blocking (or competing) with the receptor sites the opioid would use. Both Subutex and Suboxone are narcotics in the Schedule III Class I believe, which are considered to be less addictive than the drugs in the Schedule II Class, like oxycontin, fentanyl, etc. Naloxone is in Suboxone, as someone said, to prevent abuse by I.
