🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionMagaldrate is minimally absorbed systemically; its action is primarily local in the gastrointestinal tract. Simethicone is not absorbed orally and is excreted unchanged in faeces.
DistributionNot established from the available information.
Protein BindingNot established from the available information.
MetabolismNot established from the available information.
Half-LifeNot established from the available information.
ExcretionSimethicone is excreted unchanged in faeces. Magaldrate's aluminium and magnesium components may be partially absorbed and excreted renally, but this is minimal.
BioavailabilityNot established from the available information.
Onset of ActionOnset of acid neutralisation is rapid, typically within minutes of oral administration.
Peak Plasma TimeNot applicable due to local action.
Duration of ActionSymptomatic relief may last for 1 to 3 hours, depending on gastric emptying and food intake.

How It Works

This medicine combines two active ingredients. Magaldrate is a complex of aluminium and magnesium hydroxides that neutralises gastric acid, raising the pH of the stomach contents and reducing irritation to the oesophageal and gastric mucosa. Simethicone is a silicone-based polymer that lowers surface tension of gas bubbles, causing them to coalesce and be expelled more easily, thereby relieving bloating and flatulence.

Mechanism Steps

1
Acid neutralisation: Magaldrate reacts with hydrochloric acid in the stomach to form water and neutral salts, reducing acidity.
2
Gas bubble breakdown: Simethicone lowers surface tension of gas bubbles, causing them to merge and be expelled.
3
Symptom relief: The combined actions alleviate heartburn, indigestion, and bloating.
