It is hypothesized that using methylnaltrexone in addition to pain killer narcotics (opiates) in patients will result in increased tube feeding rates with more frequent nutrition at goal calorie rate.

Primary Outcome Measures:
  • Hydrogen breath test measure of bowel transit [ Time Frame: 2 days ] [ Designated as safety issue: No ]
    On day 1 Hydrogen Breath Test (HBT) measures will occur 30 minutes before test meal, immediately after test meal every 15 minutes until a rise of 5ppm is detected or until 4 hours have passed. On day 2 Hydrogen Breath test measures will occur 30 minutes before test meal, immediately after test meal and every 15 minutes until a rise of 5ppm is detected or until 4 hours have passed.

Secondary Outcome Measures:
  • Gastric residual volume measurement [ Time Frame: 3 days ] [ Designated as safety issue: No ]
    Gastric residual volumes will be measured at baseline study entry and then every 4 hours throughout the study until 24 hours post study drug administration.

Enrollment: 0
Study Start Date: October 2010
Study Completion Date: May 2012
Primary Completion Date: May 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Methylnaltrexone Drug: Methylnaltrexone
Methylnaltrexone 8 mg IV for subjects 38 to 62 kg body weight, Methylnaltrexone12 mg IV for subjects 62.1 to 114 kg body weight
Placebo Comparator: saline placebo injection Drug: Saline injection
Saline 0.4 to 0.8 ml injection

Detailed Description:
Tube feeding rates and tube feeding residual volumes will be measured and followed blinded to the treatment arm (methylnaltrexone vs. placebo) to evaluate if patients (who prior to study entry did not tolerate goal rates tube feeds) can get closer to tube feeding goal with the treatment arm.

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Inadequate tube feeding rate of greater than equal to 40% below goal rate.
  • Prescribed opiate therapy for pain or sedation, stable dose for minimum 48 hours
  • Stable dose or no dose laxative for minimum 72 hours

Exclusion Criteria:

  • Unstable Hemodynamics (eg. vasopressor medication)
  • Pregnancy
  • End stage Renal Disease on Dialysis
  • Plan to wean opiates in next 48 hours
  • Known or suspected mechanical gastrointestinal obstruction
  • Initial expired hydrogen breath level greater than 20
