mpvt are you saying that every Opioid (meaning synthetic as well as natural opiates) are metabolized into
morphine, if you are saying this than you are incorrect. The true opiates we use (codiene and morpine, as well as herion which may be considered an opioid too) are metabolized into morphine, but other than that morphine is not a main metabolite of any other painkiller. Only morphine, codiene and herion all cause morphine to present in the body. The rest of the painkillers have their own metabolization routes, with their own active metabolites (metabolites that are psychoactive). For instance,
hydrocodone (vicodin) metabolizes into hydromorphone and a few other things (not morphine like you said), while
oxycodone metabolizes into oxymorphone and a few other things. Both hydromorphone and oxymorphone are active metabolites (we use both of these as medicines on their own Dilaudid and
Opana respectively). But every opioid has its own route to metabolize. There is a lot more to this, as well as to how opioids work, but it is extremely complex and after doing A LOT of reading I stil only have an elemtary grasp of it.
I hope that everybody has a pain-free day,
