Lets not forget that depending on your dose its not necessarily positive that all of your mu receptors are antagonized. Also tramadol is a very tricky drug, it isnt just mu opiod mechanism, it works on seratonin and noradrenalin. So im guessing the empty mu receptors are taken up by the ultram and its enough that a few receptors will be sufficient to fill the ultram. Then the other mechanisms add to the high. I had a bottle of tramadol for two days now and was afraid to take it on my 4 8mg subutex a"
Suboxone is different than subutex, suboxone is buprenorphine and naloxone , and naloxone is used to clear the opiate receptors, to prevent respiratory depression in cases of overdose. And subutex is only buprenorphine. The danger is in suboxone is the naloxone, not buprenorphine.
