AstraZeneca Announces Results From Long-Term Safety Trial Of Naloxegol In Patients With Opioid-Induced Constipation

About Opioid-Induced Constipation Opioids attach to specific proteins called opioid receptors. When the opioids attach to certain opioid receptors in the gastrointestinal tract, constipation may occur. Opioid-induced constipation is a result of decreased fluid absorption and lower gastrointestinal motility due to opioid receptor binding in the gastrointestinal tract.

Globally, approximately 40–50% (28-35 million) of patients taking opioids for long-term pain develop constipation. About 40–50% (11-18 million) of those OIC sufferers achieve the desired treatment outcomes with current options that include over-the-counter and prescription laxatives.
