Clinical Trial Summary

The purpose of this study is to compare the efficacy of subcutaneous versus oral mu-opioid receptor antagonist therapy in opioid induced constipation that is refractory to other bowel regimens.

Description:

Opioid-induced constipation can lead to serious complications, including small bowel obstruction, fecal impaction, and bowel perforation. Not only are the medical complications potentially severe, patient quality of life can also be impacted. Two agents are currently available for opioid-induced constipation - oral and subcutaneous methylnaltrexone and oral naloxegol. Mechanistically, both agents antagonize the peripheral mu-opioid receptor in the gastrointestinal tract to decrease constipation without reversing the systemic analgesic effects of opiates. The literature currently available has evaluated the effectiveness of each agent, not the comparative effectiveness of these agents.
