Inclusion criteria applicable to Screening period:
1. Recorded at least 1 evaluable episode of heartburn on 2 separate days at level 4 or higher on the 9-point Likert severity scale (point 3 on a 0-8 point scale) prior to randomisation.
2. Competence in the use and completion of the e-diary.

8. Known hypersensitivity to omeprazole.
9. Concurrent participation in a study with an investigational drug or participation within 30 days of study entry.
10. Females who are pregnant, or planning a pregnancy. Females of child bearing potential not using reliable methods of birth control (the use of the combined oral pill, progestogen only pill, combined contraceptive patches, depot contraceptives or double barrier method all are acceptable as a reliable form of contraception).
11. Clinically significant laboratory abnormality or disease which, in the opinion of the Investigator, will create a risk for the patient, obscure the effects of study treatment or interfere with study results.
12.

Exclusion criteria applicable to Screening period:

Name Time Method Main Objective: The objective of this study is to compare Zegerid 20 mg suspension to<br>Losec 20 mg capsule in terms of the median time to sustained reduction of severity of heartburn associated with GERD, which is sustained for 45 minutes or more.;Secondary Objective: Key secondary objetives:<br>1. Determine the median time to sustained partial response<br>2. Determine the median time to sustained total relief from heartburn, which is<br>sustained for 45 minutes or more.<br>3. Determine the proportion of patients who have achieved sustained<br>response, sustained partial response or sustained total relief by 45, 60<br>and 90 minutes.;Primary end point(s): The primary efficacy parameter is the time to sustained response, which is defined as a reduction of 3 or more points on the 9-point Likert severity scale which is sustained for 45 minutes or more. This will be defined using the median heartburn severity at each time point.
