Pharmacology: Unique formulation produces soothing foam which floats on stomach contents. The magnesium carbonate contained in Algycon is converted to carbon dioxide which becomes entrapped within the gel formed by alginates in the presence of gastric acid then converting it into foam which floats on the surface of the gastric contents thus providing a relatively pH-neutral barrier.
Algycon have rapid onset, similar to other antacids with the added longer duration of action up to 4 hr compared to 30-40 min for conventional antacid.
