how does gaviscon work?


ATC Code: A02BX.

The physico-chemical characteristics of the GAVISCON gel, formed in contact with acidic gastric fluid, give it the following 3 properties:

  1. Its lightness allows it to float above the gastric contents at the level of the gastro-oesophageal junction,
  2. Its viscosity and coherence form a physical barrier that opposes the reflux (decrease in the number of reflux). In case of severe reflux, the gel regurgitates first in the esophagus and interposes between the esophageal wall and irritating gastric fluid,
  3.  Its alkaline pH replaces the acidic pH of the reflux liquid. Gastric pH shows that administration of GAVISCON increases the pH of 2 units in the cardia but does not change the pH in the rest of the stomach.

Its pharmacological efficacy is confirmed by studies of esophageal pH-metrics that show that GAVISCON significantly reduces the percentage of total time spent at acid pH in the esophagus (pH <4), as well as the number and the average duration of episodes of reflux.

In particular, the efficacy of GAVISCON on reflux symptoms has been established in patients with previously scarred grade I or II esophagitis.

does gaviscon have side effects?
