🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAluminium and magnesium salts are minimally absorbed from the gastrointestinal tract. Small amounts of aluminium and magnesium may be absorbed, especially in patients with renal impairment, but systemic absorption is generally negligible in healthy individuals.
DistributionAbsorbed aluminium and magnesium are distributed in the body, but because absorption is minimal, distribution is not clinically significant in normal renal function. Aluminium can accumulate in bone and brain tissue in renal failure.
Protein BindingNot established from the available information.
MetabolismAluminium and magnesium are not metabolised; they are excreted unchanged.
Half-LifeNot established from the available information.
ExcretionAbsorbed aluminium and magnesium are primarily excreted by the kidneys. Unabsorbed portions are excreted in the faeces.
BioavailabilityNot established from the available information.
Onset of ActionOnset of acid neutralisation is rapid, typically within 5 to 15 minutes after ingestion.
Peak Plasma TimeNot applicable, as systemic absorption is minimal.
Duration of ActionThe duration of acid-neutralising effect is approximately 30 to 60 minutes when taken on an empty stomach, and up to 3 hours when taken after a meal.

How It Works

This medicine works by direct chemical neutralisation of gastric hydrochloric acid. Aluminium hydroxide reacts with hydrochloric acid to form aluminium chloride and water, while magnesium hydroxide reacts to form magnesium chloride and water. This reaction raises the pH of the stomach contents, reducing the irritant effect of acid on the oesophageal and gastric mucosa. The combination also inhibits the proteolytic activity of pepsin, which is pH-dependent, further reducing mucosal injury. Unlike proton pump inhibitors or H2 blockers, this medicine does not suppress acid secretion; it only neutralises acid that is already present.

Mechanism Steps

1
Ingestion and dispersion: The suspension is swallowed and disperses throughout the stomach contents.
2
Acid neutralisation: Aluminium hydroxide and magnesium hydroxide react with hydrochloric acid to form corresponding chlorides and water, raising gastric pH.
3
Pepsin inhibition: The increase in pH reduces the activity of pepsin, an enzyme that can damage the stomach lining.
4
Symptom relief: Reduced acidity and pepsin activity lead to relief of heartburn, indigestion, and associated discomfort.
