Primary Outcome Measures:

To compare the pharmacodynamic efficacy in controlling intragastric pH (percent time pH > 4.0) following administration of esomeprazole 40 mg, lansoprazole 30 mg and pantoprazole 40 mg taken orally, once daily in pat [ Time Frame: Screening, assessments every 2 weeks. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

To compare nocturnal intragastric acid control in NSAID-using patients taking esomeprazole 40 mg, lansoprazole 30 mg or pantoprazole 40 mg once daily. [ Time Frame: Patients will be an in-patient beginning the AM of Day 5 through the AM of Day 6 during all three treatment periods. ] [ Designated as safety issue: No ]
To compare intragastric acid control utilizing thresholds other than pH 4.0 among NSAID-using patients taking esomeprazole 40 mg, lansoprazole 30 mg and pantoprazole 40 mg once daily. [ Time Frame: Patients will be an in-patient beginning the AM of Day 5 through the AM of Day 6 during all three treatment periods. ] [ Designated as safety issue: No ]
To compare the mean hourly cumulative integrated gastric acidity during the 24-hour monitoring period on Day 5 among NSAID-using patients taking esomeprazole 40 mg, lansoprazole 30mg and pantoprazole 40 mg once daily. [ Time Frame: 24-hour monitoring period ] [ Designated as safety issue: No ]
