Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • To compare the maximum acid output during pentagastrin stimulation after 10 days of Nexium dosing administered orally with 10 days dosing via intravenous administration. [ Time Frame: Every 10 days ]

Secondary Outcome Measures:
  • To compare basal acid output at steady state and when switching between Oral and IV administration of Nexium. [ Time Frame: Post Day 10 ]
  • To compare maximum acid output when switching between Oral and IV adminstration of Nexium [ Time Frame: Post Day 10 ]
  • Safety assessment via adverse event recording. [ Time Frame: At each visit ]
