An Open, Randomized, Two Way Crossover Study Comparing the Effect of 20mg Esomeprazole Administered Orally and Intravenously as a 15 Minute Infusion on Basal and Pentagastrin-Stimulated Acid Output in Subjects With Symptoms of Gastroesophageal Reflux Disease (GERD)

Study Overview
=================
Brief Summary
-----------------
This study looks at the effect on basal and pentagastrin-stimulated acid output of 40 mg Esomeprazole (Nexium) administered orally and intravenously as a 15-minute infusion to people with symptoms of Gastroesophageal Reflux Disease (GERD)

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The maximal acid output (MAO) during pentagastrin stimulation after 10 days administration of 40 mg esomeprazole for both study periods. |  | MAO will be assessed after 10 days of treatment (Day 11 or Day 20) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Basal acid output (BAO) after 10 days administration of 40 mg esomeprazole for both study periods. (Day 11 or Day 20) |  | BAO will be assessed after 10 days of treatment | 
| To compare MAO when switching (after Day 2 in the second study period versus after Day 10 in the first study period) from oral to intravenous dosing and from intravenous to oral dosing. |  | Assessments at Day 2 and after Day 10 (Day 11 or Day 20) | 
| To evaluate the safety of intravenous esomeprazole in subjects with symptoms of GERD. |  | Safety assessments throughout the study |
