How about Roxanol for pain relief?

Some time ago I posted the question about why Demerol tablets do nothing to ease pain. The answer was it works best in the IV route.

What about Roxanol? I’ve read that this is given in cases of cancer and also for the pain after having one’s tonsils removed.

Those seem rather far apart.

Anyway, would Roxanol be any better than Demerol?

Did you try the Dr Koop site? I don’t know if Roxanol has been in general use enough to get many comments from from SDMB.
