They take a lot longer to kick in, and as the naloxone, is out competed to the mu-opioid receptor anyway, I figured the different ratio, would be less naloxone, because if 4.2/0.7mgs is equal to an 8/2mg suboxone film. Then obviously 4.2 from 8, has a difference of 3.8mgs, which is over half left still of what it originally was in the suboxone. Where as the naloxone is less than half of its original dose its 0.7mgs from 2mgs. So unless naloxone bioavailability is higher than buprenorphine buccally, then I could see why. I fined the bunavail to dissolve frustratingly slow, but I think that is part of its design, its is double layered, to hold the medicine against the buccal glands, while it fully dissolves, and there is left over gunk from the extra layer, that you can either swallow or spit out, after about 1hr 30mins, which how long bunavail dissolves from me. Personally I like subocone better, it has a much more rapid release, and dissolves quickly, and fully. The suboxone has a horrible orange taste, that if you've been taking them as long as me, you don't even taste them anymore, However the bunavail has a great fruit taste, its almost like a fruit role up flavor. So there are pros and cons, but personally I'd stick with the suboxone, though I have found the bunavail brand to be cheaper.
