Sublocade doesn't have naloxone in it.
I think its a wonderful idea, I was really excited about probuphine as well when it was in the tunnel, but probuphines doses were much, much lower. Meaning it would essentially only be useful to use after tapering down to a very low dose, and using as a bridge to sobriety(which don't get me wrong, is the hardest part). This seems more geared toward actual maintenance, I'd like to see more doses though, so you could easily taper just by changing the strength of your depot without supplementing it with SL bupe, and then weak doses that you could jump off from. As is they only offer 300mg and 100mg depots, which last for 30 days, which means you are still talking about 2mg+ a day for the smaller depot.
And since we all know bupe works the best when dosing less than 2mg per day(with lower effective doses due to BA) even the 100mg is higher than I think most of us would want to use, it would cause all the negative side effects associated with high dose suboxone such as severe emotional numbing, sexual side effects, etc.
In its current form I think its best for people NEW to suboxone, who would switch to strips after the first month. This would ensure compliance without all the pain and suffering of vivitrol.
Probuphines delivery system was much more complex, I don't think this system is really suitable for use as a bridge to sobriety. Even if they lowered the depot down to say ~15mg I don't believe the delivery is consistent enough for such low doses, toward the end of month of such a small depot some parts of some days you would WD and other days you wouldn't, the landing wouldn't be smooth enough to go from depot to nothing, this is where probuphine could come in. But as is, just changing from the 300mg to 100mg depot would still need to be supplemented with suboxone.
