Les1ie Says:
where can one find a chart that lists all the opiates and then compares them to the other opiates available, mg. to mg. That is, if I took a 30mg. oxycodone, and wanted to change over to another opiate for pain management, like diaulid, how much of the oxycodone in mg. equals diaulid 8 mg.
Why are the letters I am reading on "Opiate" subject all saying, "just happened four years ago" (or more?) How do I read more current information and exchange comments based on recent formulations and newer released drugs?

Short answer is that Dilaudid 8mg ~ 27mg Oxycodone. I had to do a bit of math for the answer. Of course this is just an estimate. Most conversion charts use Morphine as the baseline so you have to back into the calculations.
Just in case you're interested in the details ... Oxycodone is about 1.5 times the strength of Morphine. Hydromorphone (Dilaudid) is about 5 times the strength of Morphine. So ... 8 (mg Dilaudid) x 5 (times Morphine potency) = 40 (mg Morphine) ... 40 (mg Morphine) / 1.5 (relative Oxycodone potency) = 26.6666...
Of course please don't just try and switch meds on your own based on these calculations, please do so with a doctor's supervision!
As for your 2nd question about recent information I find that the discussion thread lists on the site are a great way to find the most recent postings. You can list threads by drug or category. For example:
/Discuss/Oxycodone
/Discuss/Pain-Relief
Hope this helps! Let me know if you are looking for anything else.
