Exclusion Criteria

-A history of gastro-oesophageal reflux or active gastrointestinal disease (gastroduodenal ulcer, gastrointestinal haemorrhage, mechanical obstruction or perforation) within the last year.
-Clinically significant diseases of the body system.
-A medical history that is associated with an increased risk in study procedures (e.g. basal skull fracture or those who have undergone trans-sphenoidal surgery).
-Hospitalisation within the previous three months for major surgery or medical illness.
-A clinically significant illness within the 4 weeks prior to screening.
-Ingestion of any prescription medication or non-prescription medication within the seven days, prior to the screening visit, which the Principal Investigator considers may interfere with the study.
-Ingestion of antacids, H2 antagonists, motility stimulants (e.g. prokinetics, macrolide antibiotics such as erythromycin and azithromycin, and 5-hydroxytryptamine [5HT] agonists such as sumatriptan) or other medicines for relief of symptoms of acid reflux disease 2 weeks prior to enrolment in the study and during the study and/or have taken proton pump inhibitors in the 4 weeks prior to enrolment into the study and during the study. Enrolment is defined as the date of informed consent signature.
-Those who are currently taking any of the following medications: antihistamines, tetracyclines, digoxin, quinolones including fluoroquinolone, iron salts, neuroleptics, thyroxine and levothyroxine, penicillamine, beta-blockers (e.g. atenolol, metoprolol, propranolol), glucocorticoid, chloroquine, biphosphonates, ketoconazole, eltrombopag and Thiazide diuretics.
-A history of drug hypersensitivity, which in the opinion of the Principal Investigator might interfere with the study.
-A history of allergy or intolerance to either IMP or the following formulation constituents: e.g. sodium alginate, parabens (methyl and propyl), glucose syrup, carbomer, xanthan gum.
-A current or recent history (within one year of the screening visit) of alcohol abuse or significant abuse/misuse of any legal or illegal drugs, substances and solvents.

-Those who regularly (weekly) consume excessive amounts of alcohol (> 8 units for men and > 6 units for women in one consumption, excessive amounts as defined by the UK National Office of Statistics).
-Those who have consumed more than 2 units of alcohol per day in the 7 days prior to the screening visit and from the screening visit up to 48 hours before admission to the Clinical Unit for Treatment Period 1.
-Those who have consumed alcohol within the 48 hours before admission to the Clinical Unit for Treatment Period 1 and there is insufficient time for the visit to be rescheduled.
-Those who regularly consume excessive quantities of caffeine (> 6 cups of tea, coffee or cola per day), according to the Investigator’s judgement.

Primary Outcome Measures

Name	Time	Method
Secondary Objective: The secondary objective of this study is to assess the safety of the test formulation.;Primary end point(s): The primary endpoint will be the mean percentage of time that pH = 4 over 0-30 minutes post-dose across electrodes 5 to 10. The primary analysis will be the comparison of this endpoint between Gaviscon Double Action Liquid and placebo liquid, within ;Timepoint(s) of evaluation of this end point: Over a minimum of 30 minutes post-dose;Main Objective: The primary objective of this confirmatory study is to confirm the acid neutralisation action of Gaviscon Double Action Liquid versus placebo liquid, within the stomach.
