Why
  1. The study's title name Opioid-Induced Constipation, a narrower term within Constipation.
Confidence
High: the new condition is named in the study's own title. Of 46 hand-checked studies reclassified this way, 72% were exactly right and 89% in the right disease family; the registry's first term was right for 4% (measured 2026-10-21). How we classify →

Study summary

This is a double-blind, randomized, placebo-controlled trial to examine the effectiveness of adding one 25mg dose of naloxegol to the cardiac surgery pre-operative regimen.

Read the detailed description

This is a double-blind, randomized, placebo-controlled trial to examine the effectiveness of adding one 25mg dose of naloxegol to the cardiac surgery pre-op regimen. There will be 140 subjects per study group. The patient and treating physician/nurse will be blinded as to which group the subject is assigned. On the day of surgery, subjects in both groups will complete a questionnaire to assess compliance with prescribed pre-operative regimen. Subjects in both groups will receive post-operative bowel regimen in the cardiovascular intensive care unit (CVICU) according to current standard of care, including procedures for rescue medications for constipation prevention and induction of a bowel movement.
