Pharmacotherapeutic classification: A02BX13
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 Gaviscon Advance Aniseed flavour Oral Suspension is physical and does not depend on absorption into the systemic circulation.
There are no preclinical findings of relevance to the prescriber, which are additional to those already included in other sections of the SmPC.
