Research findings suggest opioids, with varying efficacy at the μ and κ receptors, produce independent effects on unique pain mechanisms and individual responsiveness for some is dependent on pain mechanism and opioid type, according to an article published in The Journal of Pain.
Participants included 139 patients who underwent thermal, pressure and ischemic experimental pain testing before and after administration of morphine and butorphanol. Based on the results, researchers established four distinct drug response profiles. Three drug profiles showed excellent analgesic efficacy produced by one type of opioid on one pain stimulus modality. However, the fourth drug response profile only showed average analgesic efficacy across all pain modalities for both opioids.
