Gaviscon

From Wikipedia, the free encyclopedia

This is a non-prescription medication for the treatment of heartburn. It is produced under patent by GlaxoSmithKline

The active antacid ingredients in Gaviscon are aluminum hydroxide and either magnesium carbonate or magnesium trisillicate

In addition to the acid-neutralizing ingredients, Gaviscon contains "alginate" (alginic acid + sodium bicarbonate). When taken by mouth the combination of the alginic acid and bicarbonate creates a foam barrier or "raft" which floats on the stomach acid.

This raft foam barrier helps reduce the number of reflux episodes and provides longer lasting action against heartburn. If reflux occurs, this raft foam barrier is the first to contact the esophageal mucosa, and thus provides protection against the gastric contents. This barrier can be expected to last up to 4 hours. This is a longer duration than traditional antacids, which last approximately 30-60 minutes.
