pharmdee, that's what you get going online before you've had your coffee.
Subutex is
buprenorphine, the kappa agonist. Suboxone is
buprenorphine plus, favorite of every junkie (LOL), nalaxone, a potent opiate antagonist. The nalaxone is there to render Suboxone useless for injection. Suboxone is not the first med to include nalaxone to discourage injection. Talwin NX tabs also contain nalaxone.
I've been told that Suboxone is only available for a 5-day detox, not maintenance.
