Opioid/naloxone prolonged release combinations for opioid induced constipation

扫码查看
I read with great interest the recent article by Chen et a/in a recent issue of your esteemed journal.The article is highly thought provoking.One emerging therapeutic alternative for opioid induced constipation is the emergence of opioid/naloxone prolonged release combinations.For instance,naloxone when administered in a 1∶2 ratio with oxycodone reverses the inhibitory effect of oxycodone on the gastrointestinal tract.The advantage of oxycodone/naloxone prolonged release (OXN) is that while its anti-nociceptive efficacy is equivalent to that of oxycodone prolonged release (OXC),it significantly decreases the "Bowel Function Index" thereby ameliorating symptoms of opioid induced constipation to a large extent.Schutter et al in a recent study have reported a decrease in the bowel function index from 38.2 to 15.1.Similarly,L(o)wenstein et al in another recent study have reported that following a month of therapy,complete spontaneous bowel movements per week is increased from one in OXC therapy to three in OXN therapy.
