5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic classification: A02BX13. Other drugs for peptic ulcer and gastro-oesophageal reflux disease.

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

5.2 Pharmacokinetic properties

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

No pre-clinical findings of any relevance to the prescriber have been reported.
