Overview & Mechanism of Action
- Gaviscon Double Action Mint Chewable Tablets (pack of 32 tablets) combines dual therapeutic mechanisms to address both hyperacidity and mechanical acid reflux:
- Alginate Raft Formation (Sodium Alginate): Reacts with gastric acid to form a resilient, low-density gel (raft) of alginic acid that floats on top of stomach contents. This physical barrier prevents acidic gastric juice from refluxing up into the esophagus during esophageal sphincter relaxation.
- Dual Antacid Acid Neutralization (Calcium Carbonate & Sodium Bicarbonate): Reacts rapidly with hydrochloric acid ($\text{HCl}$) in the gastric lumen to buffer excess stomach acid, raising intragastric $\text{pH}$ and providing fast relief from burning chest pain and epigastric discomfort.
- Dual Protection Against Pepsin & Bile: The structural raft sequesters pepsin and bile acids, protecting esophageal mucosal tissue from enzymatic digestion and chemical erosion.
