What exactly are the premeds given?  Bupenorphine, methadone, or something else?

Also what medications are used to achieve this balance while sedated?

Does this only work for accute drug dependency on shorter acting opioids like heroin, fentanyl, oxycodone etc... Or would this treatment work with someone who is currently trapped in the cycle of taking methadone from a clinic, scared to experience withdrawals.

Thanks for your time,
