PRIMARY outcome

Timeframe: 4 hours after dose on Day 4

Population: Pharmacodynamic-Evaluable Population: All participants who presented valid data from all three study periods. One participant was dropped from the Pharmacodynamic-Evaluable Population in the Prilosec OTC Tablets group because of invalid pH tracings at Day 4. Therefore, the number of participants included at Day 4 in this group was 26.

Early effectiveness of treatment is evaluated as the percent time with intragastric pH\>4 during the first 4 hours following administration of respective treatments
