Significant: Hypophosphataemia (prolonged use); hypermagnesaemia and aluminium accumulation (which may lead to osteomalacia or encephalopathy), particularly with prolonged use in patients with renal impairment. Gastrointestinal disorders: Diarrhoea, constipation, abdominal pain.
Quá liều
Symptoms: Diarrhoea, abdominal pain, vomiting, hypomotility of the bowel; may cause or aggravate intestinal obstruction and ileus in patients at risk. Management: Symptomatic and supportive treatment. Correct fluid deficiency as necessary. Treatment consists of administration of IV Ca gluconate, rehydration, and forced diuresis. Haemodialysis or peritoneal dialysis may be done as necessary in cases of renal impairment.

Tác dụng
Description: Mechanism of Action: Aluminium hydroxide and magnesium hydroxide are antacids that neutralise the secreted gastric acid, resulting in increased gastric pH and inhibition of pepsin activity.
Aluminium hydroxide, a slow-acting antacid, reacts with hydrochloric acid in the stomach to form aluminium chloride and water.
Magnesium hydroxide, a fast-acting antacid, reacts with hydrochloric acid in the stomach to form magnesium chloride and water. Duration: Aluminium hydroxide: Up to 3 hours (60 minutes after meals); 20-60 minutes (fasting state). Pharmacokinetics: Absorption: Aluminium hydroxide: Not well absorbed from the gastrointestinal tract.
Magnesium hydroxide: Bioavailability: Approx 15%. Distribution: Magnesium hydroxide: Volume of distribution: 60.2 L. Excretion: Aluminium hydroxide: Via urine (17-30%); faeces (when combined with dietary phosphate in the intestine).
Magnesium hydroxide: Via urine (up to approx 20%); faeces (as unabsorbed drug). Elimination half-life: 8.3 hours.
