Can "GAVISCON" really prevent reflux?
Is it just another antacid or does it work differently?
REPLY:
Gaviscon does not "prevent" reflux. It is "just another antacid" with claims that it works differently than other antacids.
Gaviscon is a combination of Aluminum Hydroxide and Magnesium Trisilicate; it comes in two different dose forms and each includes the ingredient alginic acid. The drug is dispensed in chewable tablets.
In the original dose Gaviscon "did not meet the minimal FDA requirements to be called an antacid. Yet the FDA has allowed the use of the term because of Gaviscon's unique action. The tablets contain alginic acid, from seaweed, which turns to a foamy gel inside the stomach. The gel, says Gaviscon's manufacturer, forms a floating barrier - a "raft" of sorts atop the stomach's contents. If those contents do reflux into the esophagus the inert foam is first to make contact."
Gaviscon has those who swear by it and others who feel it does not work.
