 The compounds used as antacids are: 1. sodium and potassium bicarbonates 2. calcium carbonate 3. aluminium hydroxide 4. magnesium and bismuth salts 5. magnesium–aluminium complexes.  MOA: These are weak bases that dissociate to form alkaline salts, thereby neutralizing gastric acidity.

 MOA: Alginates act as reflux suppressants, they form a sponge-like polymer matrix, forming barrier.  They include: 1. Alginic acid 2. Magnesium alginate 3. Sodium alginate.

 Compounds available are : Famotidine, Ranitidine.  H2-antagonists are more effective treatments than antacids for non-ulcer dyspepsia.  H2 receptor antagonists occupies receptor sites on the parietal cells (H+/K+ ATPase) blocking their activity.
