Indicated for the management of gastric reflux, reflux oesophagitis, hiatus hernia, heartburn (including heartburn of pregnancy) and similar gastric distress.
Alginic acid reduces reflux via its floating, foaming, and viscous properties. Alginic acid precipitates upon contact with gastric acid to create a mechanical barrier, or a "raft", that displaces the postprandial acid pocket. The formation of a raft is thought to occur rapidly, often within a few seconds of dosing. In clinical trials, alginic acid was effective in reducing the symptoms of gastroesophageal reflux disease (GERD). In healthy volunteers, alginic acid in combination with an antacid was effective in decreasing postprandial reflux in the upright position. Alginic acid is able to bind to cations when ingested.
Absorption
The absorption into the systemic circulation from oral formulations of alginic acid is reported to be minimal, as the mode of action of alginic acid is physical.
Route of Elimination
This pharmacokinetic parameter is unlikely to apply for alginic acid.
Volume of Distribution
This pharmacokinetic parameter is unlikely to apply for alginic acid.

Once orally administered, alginic acid reacts with gastric acid to form a floating "raft" of alginic acid gel on the gastric acid pool. Alginate-based raft-forming formulations commonly contain sodium or bicarbonate; bicarbonate ions are converted to carbon dioxide in presence of gastric acid and get entrapped within the gel precipitate, converting it into a foam which floats on the surface of the gastric contents, much like a raft on water. The "raft" has a near neutral pH due to carbon dioxide and floats on the stomach contents and potentially functions as a barrier to impede gastroesophageal reflux. In severe cases, the raft itself may be refluxed into the oesophagus in preference to the stomach contents and exert a demulcent effect.
