The purpose of this study is to determine if using Pantoprazole decreases your daytime sleepiness and improves your reaction time when compared to using a placebo (sugar pill).

Condition Intervention Phase
Acid Reflux Disease
Obstructive Sleep Apnea
Drug: Pantoprazole
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double-Blind
Primary Purpose: Treatment
Official Title: Randomized, Placebo-Controlled Trial of Pantoprazole for Sleepiness Associated With Acid Reflux and Obstructive Sleep Disordered Breathing

Further study details as provided by University of Cincinnati:

Primary Outcome Measures:
  • Difference between treatment groups with regard to change in sleepiness score (ESS)

Secondary Outcome Measures:
  • Difference between treatment groups with regard to change in reaction time testing.
  • Difference between treatment groups with regard to change in total reflux symptom scores.
  • Difference between treatment groups with regard to change in sleep related QOL (FOSQ).

Estimated Enrollment: 68
Study Start Date: August 2004
Estimated Study Completion Date: August 2006
Detailed Description:

Half of the patients enrolled in the study will begin the study taking Pantoprazole. The other half will begin the study taking a placebo (sugar pill). There is an equal chance of being placed in either group.

After two weeks, the patients will stop taking their first batch of medication to allow it to completely leave their bodies. Then the patients will begin taking the other medication so that by the end of the study, each patient will have been treated with pantoprazole for two weeks and placebo for two weeks.

At the end of each two weeks, patients will be asked to complete questionnaires regarding their daytime sleepiness and reflux symptoms. Patients will also complete reaction time testing as a measure of daytime sleepiness.
