Is methadone x5 morphine in potency? If you look at most conversion tables, they give a daily equivalent not dose equivalent. A few nations do the right thing and specify (R) methadone (it's the (S) methadone that is cardiotoxic) AKA L-Polamidon™ and levomethadone. I thought it (the (R) isomer) was around morphine in potency?
I mean, I'm happy to be wrong, but I did look at many closely related compounds (all racemic mixtures) and they were all around ½ morphine in potency.
Although HerbsQuit is happily off methadone (and I think that is a good move), I've noticed some slightly worrying details of methadone. Taken orally it's bioavailability can vary between 30% and 80%. Many sources give slightly different values but they all have a huge range. Now it's supposed to accumulate in the body so that you will over 7-10 days reach a steady state. BUT. People given methadone chronically actually metabolise it faster so you might actually start getting lower and lower plasma levels over the months and indeed years.
I mention this because I am prescribed OxyContin for chronic severe pain but it isn't working out. My own pharmacist suggested that I might do better with methadone (Physeptone tablets) but it seems like most doctors don't know much about methadone. Sorry to hijack thread. Very anxious.
