Arm Intervention/treatment
Active Comparator: 1
Zegerid®
Drug: Zegerid®
capsule(20 mg omeprazole/sodium bicarbonate), single dose

Experimental: 2
Prilosec OTC®
Drug: Prilosec OTC®
Omeprazole-magnesium 20.6 mg, tablet, single dose




Primary Outcome Measures :
  1. The Mean Percent Time Gastric pH > 4.0 on Day 1 [ Time Frame: continuously over a 24 hour period ]
    In this study, there was evidence of gastric pH probe failure and a high incidence of biologically improbable pH measurements (sustained pH < 1.0) that bring the validity of the results into question. The results of this study are, therefore, inconclusive.
