Gaviscon Peppermint Liquid has been specifically formulated for the treatment of gastro-oesophageal reflux. These symptoms include acid regurgitation, heartburn, and indigestion which may occur following meals or during pregnancy, and in those who display symptoms of oesophagitis. Gaviscon Peppermint Liquid suspension contains the active ingredients, sodium alginate, sodium bicarbonate, and calcium carbonate, which belong to a group of medicines called reflux suppressants. They work together to form a protective 'raft' on top of the stomach contents to prevent stomach acid from escaping into the oesophagus (food pipe) which causes pain and discomfort.
