Indications & Uses

Gastrica is indicated for:

Pharmacology

This medicine combines magaldrate and simethicone. Magaldrate is a magnesium aluminium compound (hydroxymagnesium aluminate). It neutralises gastric acid very quickly, and it does this without raising the pH above 5-6. It also lowers the activity of pepsin in gastric secretion.

The second component, simethicone, helps small gas bubbles join together into larger ones. This gives relief from flatulence.
