So I just got my hands on some opana 40mg Er they are orange and have G74 on them. according to strengths 5mg of opana iv would be 100 mg of oxycodone, with his normal oxy dose being 50-80mg per session. my dog crushed up 10 mg of the pill which should be 80 mg of oxy snorted because the bioavailibility is 40% and at iv at 100% 10 mg of opana would be 200 mg so 200mgx .40 which is the bioavailibility snorted would be 80 mg of oxy so I snorted the 10mg and doesnt feel nearly as high as 80 mg of oxy. Could someone explain this to me the pill crushed really easy into a powder no gel or anything. Is this because the time release is still active or something if so could someone explain how the time release works exactly? but to my dog it looks like they crush like the old oc's and are fine to snort any help would be appreciated. seen threads so plz don't link me I just want to know about this specific opana the G74 40 mg Er its orange thanks.
