<prompt> Magaldrate is converted by gastric acid to -Magnesium hydroxideMagnesium hydroxide and calcium carbonateMagnesium hydroxide and Aluminium hydroxideCalcium carbonate and aluminium hydroxide  <response>: Ans. is c i.e., Magnesium hydroxide and Aluminium hydroxide Magaldrate:o Magaldrateis a common antaciddrug that is used for the treatment of duodenal and gastric ulcers, esophagitis from gastroesophageal reflux.o Magaldrate is a hydroxymagnesium aluminate complex that is converted rapidly in gastric acid to MgOH2 and AlOH3, wrhich are absorbed poorly and thus provide a sustained antacid effect.
