Study Arms:
- Zegerid (Type: EXPERIMENTAL): Participants receiving Zegerid (omeprazole/sodium bicarbonate) in Periods 1, 2 or 3. All participants were randomized to a 3-way crossover design and received Zegerid Capsules (20 mg omeprazole/ 1100 mg sodium bicarbonate), Prevacid Capsules (15 mg lansoprazole), or no treatment in a random order. All participants also took approximately 2 oz of water with their medication.
- Prevacid® (Type: ACTIVE_COMPARATOR): Participants receiving Prevacid® (lansoprazole) in Periods 1, 2 or 3. All participants were randomized to a 3-way crossover design and received Zegerid Capsules (20 mg omeprazole/ 1100 mg sodium bicarbonate), Prevacid Capsules (15 mg lansoprazole), or no treatment in a random order. All participants also took approximately 2 oz of water with their medication.
- No treatment (Type: NO_INTERVENTION): Participants receiving No treatment in Periods 1, 2 or 3. All participants were randomized to a 3-way crossover design and received Zegerid Capsules (20 mg omeprazole/ 1100 mg sodium bicarbonate), Prevacid Capsules (15 mg lansoprazole), or no treatment in a random order. All participants took approximately 2 oz of water once daily for 7 days.

Based on this trial design, predict the completion outcome and termination type (if applicable).
