Pharmacotherapeutic classification: A02BX 13. Other drugs for peptic ulcer and
gastro-oesophageal reflux disease.
On ingestion the tablet 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 its structure, further protecting the oesophagus from
these gastric components.
The mode of action of Gaviscon Advance Tablets is physical and does not
depend on absorption into the systemic circulation.
Preclinical safety data
No pre-clinical findings of any relevance to the prescriber have been reported.
