Action
Description:
Mechanism of Action: Aluminium hydroxide is an inorganic salt. It neutralises hydrochloride in the stomach, thereby causing elevated gastric pH and inhibition of pepsin activity. Additionally, it binds phosphate in the gastrointestinal tract, forming insoluble complexes, thus preventing the absorption of phosphate. As a topical agent, it provides temporary relief and protection for certain skin conditions.
Duration: 20-60 minutes (fasting state); up to 3 hours (1 hour after meals).
Pharmacokinetics:
Excretion: Via urine (17-30%); forms a combination with dietary phosphate in the intestine and is excreted in the faeces.
