| Measure | Time frame |
|---|---|
| Main Objective: Primary objective: - To compare the proportion of time with intragastric pH>4 during the first 12 hours after study drug administration on Day 1, between treatment with a fixed combination of famotidine 10 mg and omeprazole 20 mg (OX17) and with mono-treatment with omeprazole 20 mg. The primary variable is the proportion of time with intragastric pH>4 during the first 12 hours after study drug administration on Day 1;Secondary Objective: Secondary objectives: - To compare time to pH>4 on Day 1 between treatment with a fixed combination of famotidine 10 mg and omeprazole 20 mg (OX17) and with mono-treatment with omeprazole 20 mg. The variable is pH>4. - To compare the 24-hour intragastric pH profile (acid-suppressive effect) between treatment with a fixed combination of famotidine 10 mg and omeprazole 20 mg (OX17), mono-treatment with famotidine 10 mg and omeprazole 20 mg. The pH profile of the treatments will be evaluated, tested and compared using variables derived from the 24-hour pH-metry. - To assess and compare the efficacy of each study treatment with regard to the need for antacid rescue medication during the treatment periods. - To assess tolerability and safety of treatments - To assess symptoms during treatment (patient diary 2) and baseline (patient diary 1);Primary end point(s): Primary endpoint: pH registration samples every 4 seconds after drug administration and for 24 hours. | — |
