PHARMACOLOGICAL PROPERTIES

5.1
Pharmacodynamic properties
On ingestion the 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 Gaviscon Cool Liquid is physical and does not depend
on absorption into the systemic circulation.

5.3.

Preclinical safety data
No preclinical findings of relevance to the prescriber have been reported
