Inclusion criteria

  • Normal subjects who are 18-65 years of age;
  • Non-childbearing potential females or those using birth control

Treatment and study plan

Zegerid®

Drug

capsule(20 mg omeprazole/sodium bicarbonate), single dose

Prilosec OTC®

Drug

Omeprazole-magnesium 20.6 mg, tablet, single dose

Primary outcomes

  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.
