Pharmacotherapeutic group: Other drugs for peptic ulcer and gastro-oesophageal reflux disease (GORD).
ATC code: A02BX.
On ingestion the suspension reacts with gastric acid to rapidly form a raft of alginic acid gel having a near-neutral pH which floats on the stomach contents quickly and effectively impeding gastro-oesophageal reflux for up to 4 hours, and protecting the oesophagus from acid, pepsin and bile. In severe cases the raft itself may be refluxed into the oesophagus in preference to the stomach contents and exert a demulcent effect. In addition in vitro evidence has shown that the raft has a secondary action and is able to entrap bile and pepsin within its structure, further protecting the oesophagus from these gastric components.
The mechanism of action of the medicinal product is physical and does not depend on absorption into the systemic circulation.
No preclinical findings of relevance to the prescriber have been reported.
Methyl parahydroxybenzoate E218
Propyl parahydroxybenzoate E216
Sodium hydroxide for pH adjustment
