Treatment of symptoms resulting from the reflux of acid, bile and pepsin into the oesophagus such as acid regurgitation, heartburn, indigestion (occurring due to the reflux of stomach contents), for instance, after gastric surgery, as a result of hiatus hernia, during pregnancy, accompanying reflux oesophagitis, including symptoms of laryngopharyngeal reflux such as hoarseness and other voice disorders, sore throats and cough. Can also be used to treat the symptoms of gastro-oesophageal reflux during concomitant treatment with or following withdrawal of acid suppressing therapy.

Each 10 ml dose contains about 5.1mmol of sodium and 2mmol of potassium. This should be taken into account when a highly restricted salt diet is recommended, e.g in some cases of congestive cardiac failure and renal impairment or when taking drugs which can increase potassium levels.
Each 10ml contains 200 mg (2.0 mmol) of calcium carbonate. Care needs to be taken in treating patients with hypercalcaemia, nephrocalcinosis and recurrent calcium containing renal calculi.
Parahydroxybenzoates (E214, E216) may cause allergic reactions (possibly delayed)

ATC Code: A02BX13
Pharmaceutical group: Other drugs for peptic ulcer and gastro-oesophageal reflux
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 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 it structure, further protecting the oesophagus from these gastric components.
The mode of action of the product is physical and does not depend on absorption into the systemic circulation.
There are no preclinical data of relevance to the prescriber in addition to that included in other sections of the SmPC.
