Trial summary

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 hypothesized that even a small amount of stomach acid backing up and entering the mouth can increase post-tonsillectomy pain. Read more about this study

About this study

Official title: The Effects of Gastro-esophageal Acid Suppression on Post-tonsillectomy Pain

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 hypothesized 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.

Read the detailed description

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 randomized 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.
  1. 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

    Also called Prevacid

    If weight is less than 30 kg, 15 mg of Lansoprazole twice daily will be administered. If weight is greater than or equal to 30 kg, 30 mg of Lansoprazole twice daily will be administered.

  • PlaceboDrug

    Placebo will also be administered based on weight.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Primary Outcome is the Number of Days to Become Free of Narcotic Pain Medication.

    Measured: 2 weeks

Secondary outcomes (1)
  1. The Secondary Outcomes Are the Number of Days to be Free of Pain, the Number of Days to Return to Normal Activity Levels and the Number of Days to Return to Normal Fluid Intake.

    Measured: 2 weeks

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

A Phase 4 study testing Lansoprazole in people with Post-tonsillectomy Pain and Post-tonsillectomy Activity, run by Boston Children's Hospital at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 6 Dec 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Yes. Results are posted in the registry (first posted 6 Dec 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Primary Outcome is the Number of Days to Become Free of Narcotic Pain Medication. (time frame: 2 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
