Efficacy and Speed of Action of a Product to Control Gastric Hydration and Gastroesophageal Reflux

Study Off Efficacy and Rapidity of Action of a Product With Sodium Alginate, Calcium and Magnesium Salts, Hyaluronic Acid and Aloe Vera to Control Oesophageal-Gastric Acidity (pH), Symptoms of Gastric Reflux and Hyperacidity

A Randomised, Placebo-Controlled Clinical Trial off the Efficacy and Rapidity of Action of a Product Containing Sodium Alginate, Calcium and Magnesium Salts, Hyaluronic Acid and Aloe Vera to Control Oesophageal-Gastric pH and Reduce Symptoms of Gastric Reflux and Hyperacidity.

The investigators will include patients with gastroesophageal reflux disease and heartburn (more than 3 weekly episodes of heartburn for at least 4 consecutive weeks) not related to medication intake and don't use proton pump blockers or H2-receptor antagonists.

This is a multicentre clinical trial with two-phase design:

Phase I: A double-blind, randomised, placebo-controlled clinical trial to assess the efficacy and rapidity of action of the medical device to reduce clinical symptoms of gastric reflux and hyperacidity under normal conditions of use. This phase I will be performed in primary care clinics.

Phase II: A non-comparative, non-controlled clinical trial to objectively assess, using continuous pH monitoring, the magnitude and rapidity to control gastric and oesophageal pH after taking the product. This phase II will be performed at the Department of Gastroenterology of Medic Center.

The study will begin with the baseline visit (day 0) in which the inclusion and exclusion criteria will be confirmed, the signing of informed consent will be obtained, GERD-Q Questionnaire will be done and treatment will be prescribed, followed by a home recording where patients will record data on episodes of acidity and heartburn occuring during the follow-up week. A face-to-face visit will be at 7 days after to recollect information about total number of daytime and nighttime episodes of acidity/heartburn since the previous visit and repeat the GERD-Q Questionnaire.

Inclusion Criteria:

• Patients of both sexes over 18 years of age
• Patients with gastroesophageal reflux disease and heartburn (more than 3 weekly episodes of heartburn for at least 4 consecutive weeks) not related to medication intake
• Patients not on proton pump blockers or H2-receptor antagonists
• Patients able to understand the study implications and who sign the informed consent.

Exclusion Criteria:

• Pregnant or nursing women
• Patients who are currently using or have used other medications or antacid products for the treatment of reflux and hyperacidity symptoms within 7 days prior to enrolment in this study.
• Patients treated with antihypertensive drugs, calcium channel blockers or non-steroidal anti-inflammatory drugs (NSAIDs)
• Patients with hypercalcaemia, hypertension, renal failure or other conditions in which the use of the components of the investigational product is not recommended.
• Patients with serious diseases that, in the physician's opinion, could interfere with the results of the study or prevent their participation in it.
