Magaldrate (INN) is a common antacid drug that is used for the treatment of duodenal and gastric ulcers, esophagitis from gastroesophageal reflux.

Available forms[edit]

Magaldrate is available in the form of oral suspension or tablets.

Pharmacology[edit]

Magaldrate is a hydroxymagnesium aluminate complex that is converted rapidly by gastric acid into Mg(OH)2 and Al(OH)3, which are absorbed poorly and thus provide a sustained antacid effect.[1]

Interactions and adverse reactions[edit]

Magaldrate may negatively influence drugs like tetracyclines, benzodiazepines, and indomethacin. High doses or prolonged usage may lead to an increment of defecation and a reduction in feces consistence. In some cases it can alter the functionality of the gastrointestinal tract, occasionally provoking constipation or diarrhea.
