I work in a residential hospice and am comfortable with opioid dosing and most equianalgesic conversions. Lately, I am seeing more oxycodone/Oxycontin prescribed as opposed to when I started with hospice and the gold standard opioids for pain and dyspnea were morphine and MSContin. Of course, we see a fair share of Dilaudid, Fentanyl, Methadone, hydrocodone, etc.
Does anyone know of any information out there about the relative efficacy of morphine vs. oxycodone for pain and dyspnea? Anecdotal reports would be fine, but I'm looking for some solid research as well, including the differences in the method of action of the two drugs.
