The World Health Organization's ATC classification organizes medical drugs based on therapeutic properties, chemical composition, and anatomy. It helps make essential medicines readily available globally and is widely used in the pharmaceutical industry.
Almagate is an aluminium- and magnesium-containing antacid.
Almasilate is an antacid compound, consisting of a crystalline aluminum/magnesium silicate polymer. It guffers gastric acid by binding hydrogen ions within the polymer.
Hydrotalcite is a layered double hydroxide of general formula Mg6Al2CO3(OH)16·4(H2O), whose name is derived from its resemblance with talc and its high water content. The carbonate anions that lie between the structural layers are weakly bound, so hydrotalcite has anion exchange capabilities. Hydrotalcite is also used as an antacid.
Magaldrate is a common antacid drug that is used for the treatment of duodenal and gastric ulcers, esophagitis from gastroesophageal reflux.
