Aluminium hydroxide is an inorganic compound commonly used as an antacid for the symptomatic relief of heartburn, acid indigestion, and peptic ulcers. It works by neutralizing excess stomach acid. It has also been used as a phosphate binder in patients with chronic kidney disease, though this use has declined due to potential toxicity. It is an approved and widely used over-the-counter medication.
Pharmacokinetics
No formal published pharmacokinetic model parameters are available for aluminium hydroxide in humans, as absorption from the gastrointestinal tract is minimal and it acts locally in the stomach. The following estimates are provided based on general knowledge of the drug's pharmacology and information from non-specific sources.
