Indications & Uses

Pharmacology

Aluminium Hydroxide, Magnesium Hydroxide, and Simethicone are combined here as a reliable, long-acting antacid with antiflatulent action. The Aluminium Hydroxide and Magnesium Hydroxide neutralize gastric acid released by the stomach's parietal cells, easing the discomfort of ulcers, since they do not act systemically.

Simethicone works differently, through its antifoam action. It spreads across the surface of liquids in the gut as a thin, low-tension film that breaks down foam bubbles. In doing so, it repeatedly lets gas bubbles trapped in mucus merge together so the gas can be passed more easily. This makes it useful for relieving flatulence, bloating, and abdominal distension, for easing dyspepsia, and for clearing gas, air, or foam from the gastrointestinal tract before radiographic imaging.

Simethicone itself is physiologically inert. It is not absorbed from the gastrointestinal tract, so it does not interfere with gastric secretion or nutrient absorption, and after oral use it passes out unchanged in the feces.
