4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction

Antacids are known to reduce the absorption of certain medicines including tetracyclines and iron salts.

Animal studies are insufficient with respect to effects on pregnancy/embryonal/foetal development/parturition and postnatal development.

Caution should be exercised when prescribing to pregnant women.

No side effects associated with sodium bicarbonate except when taken in excess.

Rebound hyperacidity may occur with prolonged dosage.

4.9 Overdose

Hypermagnesaemia – intravenous administration of calcium salts.

Hypernatraemia – give plenty of salt free fluids.

Hypercalcaemia – remove source of calcium.

5. Pharmacological Properties

5.1 Pharmacodynamic Properties

Sodium bicarbonate, calcium carbonate and magnesium carbonate are antacids. They act by neutralising the hydrochloric acid produced by the stomach and thus reducing gastric and duodenal irritation.

5.2 Pharmacokinetic Properties

Calcium Carbonate

Calcium carbonate is converted to calcium chloride by gastric acid. Some of the calcium is absorbed from the intestines but about 85% is reconverted to insoluble calcium salts, such as the carbonate and is excreted in the faeces.

Magnesium Carbonate

Magnesium carbonate reacts with gastric acid to form soluble magnesium chloride and carbon dioxide in the stomach. Some magnesium is absorbed but is usually excreted rapidly in the urine.

Sodium Bicarbonate

Administration of sodium bicarbonate by mouth causes neutralisation of gastric acid with the production of carbon dioxide. Bicarbonate not involved in that reaction is absorbed and in the absence of a deficit of bicarbonate in the plasma, bicarbonate ions are excreted in the urine that is rendered alkaline with an accompanying diuresis.

5.3 Preclinical Safety Data

The active ingredients in Bisodol Indigestion Relief Tablets have a well documented safety record.
