10-20 mL PO between meals & qHS
Pharmacology
This drug is well-balanced combination of essential non-systemic antacids which excel in efficacy and palatability. These are dependable antacid preparations without acid rebound, constipating or cathertic effects. Both the preparations provide symptomatic relief of hyperacidity associated with heartburn, acid ingestion or sour stomach.Aluminium hydroxide gel, a slow acting antacid and an adsorbent with prolonged effect, has high neutralizing power. Magnesium Hydroxide possesses a slow but sustained acid neutralizing property. Antacids of both tablet and suspension possess adsorbent property. They form a protecting coating over the ulcer surface facilitating its healing; thus protecting the sensitive mucosa of stomach and duodenum from further irritation.
Dosage and Administration
Administration:
Aluminium Hydroxide: Enhanced absorption with citrates or ascorbic acid. Decreases absorption of allopurinol, tetracyclines, quinolones, cephalosporins, biphosphonate derivatives, corticosteroids, cyclosporin, delavirdine, Fe salts, imidazole antifungals, isoniazid, mycophenolate, penicillamine, phosphate supplements, phenytoin, phenothiazines, trientine.
Magnesium Hydroxide: Decreases absorption of tetracyclines and biphosphonates. Separate administration of these and other drugs by around 2 hr.
Adult Dose:
Chronic renal impairment; CHF; oedema; cirrhosis and low Na diets; patients with recent GI haemorrhage. Administer 2-3 hrs before/after another medication to minimise drug interactions. Pregnancy and lactation.
Lactation: excretion in milk unknown; use caution
Renal Dose:
Alumunium hydroxide acts on the HCl in the stomach by neutralization, forming aluminium chloride salt and water.
Magnesium hydroxide increases peristaltic activity causing osmotic retention of fluids, thus resulting in bowel evacuation. It also reduces stomach acid by reacting with hydrochloric acid to form Mg chloride.
Interaction
Hypersensitivity to aluminium salts.
Contraindications
This is contraindicated in hypophosphataemia. It is also contraindicated in alkalosis and hypermagnesaemia where abdominal distention may be due to partial or complete intestinal obstruction.
Side Effects
Long term use of any antacid results in alkaluria, which may predispose to nephrolithiasis by forming precipitation of calcium phosphate.
Pregnancy And Lactation
It is advised to avoid antacid preparations in the first trimester of pregnancy.
