Chemical formula: AlH₃O₃ Molecular mass: 78.004 g/mol PubChem compound: 10176082
In the gut, aluminium hydroxide absorbs phosphate ions. This reduces absorption of phosphate into the body, and thereby reduces serum phosphate levels.
Aluminium hydroxide is a slow-acting antacid. It is used to provide symptomatic relief in gastric hyperacidity. In addition, the antipeptic and demulcent activity of aluminium hydroxide helps to protect inflamed gastric mucosa against further irritation by gastric secretions.
Aluminium hydroxide is slowly but perhaps incompletely converted to aluminium chloride in the stomach. Some absorption of soluble aluminium salts occurs from the gastro-intestinal tract with some excretion in the urine. Some unabsorbed aluminium hydroxide combines with phosphates and some form carbonates and salts of fatty acids, all these salts are excreted in the faeces.
