• History of peptic ulcer disease or other acid related gastrointestinal symptoms or heartburn with a frequency of more than one/month.
• Positive H. pylori breath test at screening.
• Participation in any study of an investigational treatment in the 30 days before Screening or participation in another study at any time during the period of this study
• Any significant medical illness that would contraindicate participation in the study
• Gastrointestinal disorder or surgery leading to impaired drug absorption
• Any significant mental illness, such as schizophrenia or bipolar disorder
• History (in the past year) suggestive of alcohol or drug abuse or dependence, or excessive alcohol use (>2 units per day on average; for example >2 bottles of beer, >2 glasses of wine, >2 ounces of liquor/spirits), or excessive alcohol use during the study
• Any abnormal Screening laboratory value that is clinically significant in the investigator's opinion
• Currently using or use of any prescription or over the counter (OTC) medications that affect gastrointestinal function, including first generation antihistamines (e.g. diphenhydramine) and anticholinergic agents within 7 days prior to 1st treatment administration.
• Currently using, or use within 14 days of first treatment administration, or having a history of frequent use of antacids, OTC or Prescription (Rx) H2 receptor antagonists, or OTC or Rx use of proton pump inhibitors.
• Positive urine drug/alcohol test at Screening.
