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)

Condition Intervention Phase
GERD Drug: Esomeprazole Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open, Randomized, Two-way Crossover Study Comparing the Effect of 40mg 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).

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • The maximal acid output (MAO) during pentagastrin stimulation after 10 days administration of 40 mg esomeprazole for both study periods. [ Time Frame: MAO will be assessed after 10 days of treatment (Day 11 or Day 20) ]

Secondary Outcome Measures:
  • Basal acid output (BAO) after 10 days administration of 40 mg esomeprazole for both study periods. (Day 11 or Day 20) [ Time Frame: 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. [ Time Frame: 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. [ Time Frame: Safety assessments throughout the study ]
