🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary actions. Magaldrate is a balanced mixture of aluminium and magnesium hydroxides that neutralises gastric acid, raising gastric pH and reducing pepsin activity. Simethicone is a non-absorbed surfactant that lowers surface tension of gas bubbles in the gastrointestinal tract, causing them to merge into larger bubbles that are more easily passed. Together, they provide rapid relief from acid-related symptoms and bloating.
