Pharmacotherapeutic classification: A02 BX, Other drugs for peptic ulcer and gastro-oesophageal reflux disease

On ingestion the suspension reacts with gastric acid to form a raft of alginic acid gel having a near-neutral pH and which floats on the stomach contents effectively (up to 4 hours) impeding gastro-oesophageal reflux. In severe cases the raft itself may be refluxed into the oesophagus in preference to the stomach contents and exert a demulcent effect.

The mode of action of this product is physical and does not depend on absorption into the systemic circulation.
