This study was designed to determine whether post-operative pain following a tonsillectomy can be reduced by adding an antacid-like medication to the medications taken after surgery. It is hypothesised that even a small amount of stomach acid backing up and entering the mouth can increase post-tonsillectomy pain. Therefore, the use of an antacid-like medication should help to decrease pain and reduce the amount of narcotic medication required for pain control.

Further Details

Primary Outcome Measures:

  • The primary outcome is the number of days to become free of narcotic pain medication.
    [Time Frame: 2 weeks]
    [Designated as safety issue: No]

Secondary Outcome Measures:

  • The secondary outcomes are the number of days to be free of pain, the number od days to return to normal activity levels and the number of days to return to normal fluid intake.
    [Time Frame: 2 weeks]
    [Designated as safety issue: No]

This study has been limited to children and adolescents ages 5-18 who are undergoing tonsillectomy for an indication of obstructive sleep disturbance (snoring, choking/gasping or pauses in breathing during sleep.)

Study participants will be randomised to two groups: study medication (Lansoprazole) or an inactive substance(placebo).

Participants will be asked to do all of the following:

  1. Take the study medication twice a day for 14 days.
  2. Keep a log book which will include:
    • Record the medications and amount of each medication taken each day for 14 days. This includes pain medication and the study drug.
    • Record your child’s activity level daily for 14 days.
    • Collect your child’s urine one time daily and test it using special medicated strips to monitor their daily liquid intake for 14 days.
  3. Meet with a Research Assistant or Study Physician 14-21 days after the study to collect the log book and perform a post-operative examination.
